2011 YUKON AND YUKON XL FAMILY OFFERS EXCEPTIONAL CAPABILITY, COMFORT AND
REFINEMENT

The Yukon and Yukon XL family of full-size SUVs continues to offer an uncompromising package of
capability, comfort and refinement. They offer distinctive styling, spacious and refined interiors,
exceptional driving characteristics and segment-leading safety features – including standard head
curtain side air bags for all seating rows on all models.


Yukon Denali and Yukon XL Denali return for 2011, equipped with style, technologies and luxury
features that have made these models so popular. Changes for 2011 include OnStar 9.0, with
Automatic Crash Response, and two new exterior colours: Mocha Steel Metallic and Carbon Black
Metallic.


Yukon provides a smooth, confident and secure driving experience, with its 2,946 mm (116 in.)
wheelbase, overall length of 5,130 mm (202 in.) and wide track that complements the long wheelbase.
Yukon XL models have exterior dimensions similar to the regular models, but are about 35 cm (14 in.)
longer in wheelbase and 50 cm (20 in.) more in overall length. Both Yukon and Yukon XL are available
in SLE (cloth trim) and SLT trim (leather appointments), as well as 2WD and 4WD configurations.
Yukon XL offers a three-quarter-ton model. A third-row seat is standard on all Yukon models.
For improved fuel economy, Yukon and Yukon XL models feature a 5.3L V-8 with GM’s fuel-saving
Active Fuel Management technology. The 5.3L and 6.2L engines are capable of running on E85; in fact,
all Yukon 4WD and Yukon XL half-ton models come standard with the E85-capable version of the 5.3L
V-8. GM vehicles with E85 capability can run on 100-percent gasoline, E85 or any combination of the
two.


Technologies


The Yukon family packs a lengthy roster of standard and available technologies, designed to enhance
safety and make the driving experience more enjoyable. They include:
      Bluetooth connectivity, enabling hands-free calling with controls on the steering wheel
      XM Satellite Radio
      A power-assisted tailgate, designed to open or close itself via a switch inside the tailgate door,
       on the overhead console or the key fob
      Side blind zone alert system available on SLT and Denali models. It uses radar sensors behind
       the rear fascia on both sides of the vehicle that signal an audible and visual alert if objects are
       detected in “blind zones”
      Rearview camera system – available with or without the navigation system – provides a remote
       view directly behind the vehicle via a 3.5-inch screen inside the rearview mirror or the navigation
       screen (if equipped)
      Remote start, (optional) enables the climate system to heat or cool the vehicle’s interior prior to
       occupant use
      Power-adjustable steering wheel. It’s offered exclusively on Denali models and delivers steering
       wheel position adjustability with an easy entry/exit feature
      Third-row DVD entertainment system is available and includes a flip-down screen and system
       controls for third-row passengers (Yukon XL and Yukon XL Denali only)
      USB connectivity in the centre console, enabling stored audio files to play through the audio
       system and battery charging for some handheld devices
      Heated/cooled seats available on SLT and standard on Denali models. These leather-trimmed
       front seats incorporate both heating and cooling features that increase comfort in all climates
      Integrated brake controller works with the ABS system to provide immediate and measured
       brake force signalling to electric-controlled trailer brake systems. With it, there is no requirement
       for external and/or aftermarket brake control systems (Yukon and Yukon XL models only).
Interior refinement and versatility


The Yukon and Yukon XL are available in two trim levels: SLE (cloth) and SLT (leather). Both feature a
spacious and refined environment, thanks to a premium tone-on-tone colour scheme and a lower-
positioned instrument panel. A third-row seat is standard on all Yukon models.


Sculpted seat designs and detailed trim affirm the vehicles’ craftsmanship, which is bolstered by
optional amenities such as heated seats for first- and second-row passengers. Also, the front seats
offer plenty of fore/aft and recline travel, and the second-row seats have a comfortable angle for the
seatback recline.


Craftsmanship is seen in unexpected areas, such as distinctive sill plates that greet occupants when
the doors are opened, and there are no exposed fasteners or hardware on the pillars, seats or seat
tracks. The seats have “close-outs” that surround the seat bottoms and seat tracks, creating a more
finished appearance. The undersides of the seats are covered, too, when folded.


The Yukon and Yukon XL also offer an industry-exclusive power fold-and-tumble second-row seat
feature that eases access to the third-row seat. The power fold-and-tumble second-row seats feature
release buttons accessible by the driver on the overhead console or on the interior C-pillar to provide
an easy, immediate release of the seat and an access path to the third-row seat or cargo area.


Yukon and Yukon XL interiors are versatile, too. The third-row seats fold flat and are easily tumbled
forward or removed for maximum cargo area. Also, the centre console storage compartment, at 20.1
litres of capacity, is the segment’s largest. The glove box offers significant storage space, too, and
features damped opening operation that bolsters quietness and refinement.


Yukon Denali models


GMC’s unique Yukon Denali models are available in standard and extended-length versions, and are
instantly identifiable by their signature chrome honeycomb grille and monochromatic exterior
appointments.


Standard features include 20-inch wheels, power liftgate, power release second-row fold-and-tumble
bucket seats, head curtain side air bags, power-adjustable pedals, electrochromic (auto-dimming)
inside mirror, remote start system, rearview camera system and ultrasonic rear parking assist. From an
entertainment standpoint, the vehicles come standard with an AM/FM MP3-capable radio with a six-
disc in-dash CD changer, Bose 10-speaker Centerpoint Surround Sound audio system and XM Satellite
Radio.


The interiors of the Yukon Denali and Yukon XL Denali offer style and luxury, including standard
Nuance leather-covered seating with heated first- and second-row captain’s seats, as well as leather
trim throughout – including a Denali-exclusive leather-wrapped steering wheel with a host of auxiliary
controls. A power and heated steering wheel with Easy Entry/Exit is standard on all Denali models.
Soft, low-gloss materials for the instrument panel and other trim pieces complement the upscale styling.
The harmonious colour and grain of the materials were carefully selected to provide a premium feel as
well as durability. Flush-mounted HVAC controls and radios, with almost imperceptible gaps, convey
precision and integration, as do dampened doors for the centre console storage and cupholders.
Chrome accents are on instrument surrounds, vents and other trim. Automatic tri-zone climate control is
standard.


The Denali models also offer several helpful and convenient options, including a power sunroof, power-
retractable assist steps and a rear-seat, DVD-based entertainment system, a third-row DVD
entertainment system (Yukon Denali XL) and side blind zone alert system.


Driving experience


The Yukon and Yukon XL, available in 2WD and 4WD, are built on GM’s full-size SUV platform, which
incorporates features such as a fully boxed frame, coil-over-shock front suspension and rack-and-
pinion steering. The frame supports wide front and rear tracks that enhance stability and driving
confidence through a more secure road feel and a lower centre of gravity.


Yukon rides on a 2,946 mm (116 in.) wheelbase, with an overall length of 5,130 mm (202 in.). Its wide
track complements the long wheelbase to provide a smooth, confident and secure driving experience.
Yukon XL models have exterior dimensions similar to the regular models, but are about 35 cm (14 in.)
longer in wheelbase and 50 cm (20 in.) longer in overall length. The front suspension consists of a coil-
over-shock design that delivers linear, solid and unwavering ride and handling characteristics on all
road surfaces.
A rack-and-pinion steering system provides precise and responsive control and enhanced on-centre
feel. Yukon and Yukon XL models use a highly refined five-link rear suspension that provides superior
isolation and ride, with larger, firmer brackets that also contribute to the vehicles’ precise driving
manners.


Large, four-wheel disc brakes and a sophisticated ABS system ensure shorter braking distances and
segment-leading performance. Larger vented front and rear brake rotors, stiff dual-piston callipers and
long-life brake pads contribute to enhanced pedal feel, reduced brake noise and predictable, linear
brake response. A Bosch 8.0 next-generation four-channel ABS system is standard. The ABS system
works with the standard StabiliTrak electronic stability control system with traction control. It
incorporates rollover mitigation – software algorithm technology that uses sensors to proactively predict
vehicle “tip-up,” and applies appropriate brake forces to help prevent such events.


Enhanced driving control and ride smoothness are offered with the available Autoride real-time
damping system (standard on Denali), which uses electronically controlled shock absorbers to make
nearly instantaneous damping adjustments. The system “reads” the road and anticipates the best
damping rates. Eighteen-inch wheels are standard on Yukon and Yukon XL 2WD models, with 17-inch
wheels standard on 4WD. Twenty-inch wheels are available – including a chrome-clad design. The tires
are tailored to the vehicles to provide excellent balance of handling, quietness and safety. Yukon HD
comes standard with 17-inch wheels, while the Yukon Denali lineup is equipped with 20-inch wheels.


Safety features


The Yukon and Yukon XL offer a 360-degree perimeter safety system of occupant protection and crash
avoidance technologies. Standard features include head curtain side air bags for all seating rows and
front-seat safety belt pretensioners that are linked to the vehicle's sensing system to provide segment-
exclusive deployment in rear-end crashes. These features are integrated into a stronger vehicle
structure that is also designed for improved compatibility with other vehicles.


The head curtain air bags include design features that provide increased rollover protection and
occupant containment. Sensors located at the front of the vehicle, in the side doors, and within the
occupant compartment provide increased and more immediate crash detection. The vehicle's sensing
system provides segment-exclusive capability to deploy front seat safety belt pretensioners during
certain rear-end collisions, enhancing the belt system's ability to hold the occupants firmly in place.
The head curtain side air bag system incorporates one of the segment's first rollover indication sensors,
which is located on the vehicle's centre tunnel in the occupant compartment. The sensor monitors the
vehicle's acceleration and roll rate. If these signals indicate an impending rollover, the roof-mounted
head curtain side air bags deploy to provide an extra measure of occupant protection and containment.
These head curtain side air bags stay inflated longer than air bags developed only for side impacts
because rollover incidents can last longer. The deployment duration and other design features of the
head curtain air bags combine to provide increased occupant protection and the ability to help keep
occupants inside the vehicle.


More of Yukon and Yukon XL’s safety features include:
      Standard StabiliTrak stability control system with traction control and rollover mitigation
       technology
      Standard dual-stage driver front air bag
      Standard dual-stage outboard-front passenger air bag with passenger sensing system
      Standard head curtain side air bags for all seating rows
      Standard front seat safety belt pretensioners with rear-impact deployment capability
      Standard tire pressure monitoring system
      Available Ultrasonic rear parking assist that can detect certain stationary objects in the rearward
       path of the vehicle and send an audible warning sound (standard on SLT and Denali models)
      Available rearview camera system designed to provide the driver with a view of people or
       objects in the rearward path of the vehicle
      Standard pull-up/push-down power window switches
      Available voice-assisted navigation system
      Available Side Blind Zone Alert system (SLT and Denali)
      OnStar 9.0 with Automatic Crash Response.
