18 _ SIERRA
The sm a r Te s T Technology wins.
For over a century, GMC has been engineering great, hardworking, long-lasting trucks, and everything we’ve learned is showcased in the 2011 Sierra 1500. From its
strong yet lightweight hydroformed frame rails on up, Sierra 1500 displays the intelligent and meaningful technologies that the GMC name has come to signify.
HIGH-STRENGTH FRAME RAILS
The Sierra 1500 frame features extremely strong, fully boxed hydroformed front
frame sections. The middle sections of the frame are also made of strong
boxed sections, to provide strength where it’s needed most to handle heavy
loads. The rails taper at the rear to reduce unnecessary weight.
REDUCED MAINTENANCE
All Sierra gas engines feature extended life accessory drive belts, extended
life coolant and extended life spark plugs to help reduce your overall cost
of ownership. The Dexron V
TM
transmission uid is validated “ll for life,”
meaning the original uid is designed to last the service life of the truck,
under normal driving conditions.*
AUTOTRAC
TM
4X4
In addition to the usual 2HI, 4HI and 4LO and neutral operating modes, Sierra
SLE and SLT’s Autotrac 4x4 drivetrain includes an ‘Auto’ setting. When engaged,
the system constantly monitors for wheelspin and automatically adjusts torque
distribution to the front and rear wheels as the situation requires.
DRIVER INFORMATION CENTRE
The Driver Information Centre (DIC) monitors a wide range of functions like
transmission coolant temperature and engine oil life. On SLE and SLT models it
also features an exterior temperature readout and an 8-point compass display.
TIRE pRESSURE MONITORING SySTEM
Any time your Sierra is riding on an improperly inated tire, the standard
tire pressure monitoring system will deliver an alert via the Driver
Information Centre. Properly inated tires extend tire life and reduce
fuel consumption.
GM OIL LIFE MONITORING SySTEM
This system automatically assesses your engine oil condition and alerts
you when a change is required. The benets can include reduced oil change
frequency, which cuts down service requirements and helps minimize your
consumption of non-renewable resources.
SUSpENSION CHOICES
Sierra 1500 suspension systems include:
• Z83 Solid Smooth Ride with 35 mm twin-tube shocks and a 36 mm front
stabilizer bar.
• Z85 Handling/Trailering, with increased capacity from its 46 mm monotube
shocks and a 36 mm front stabilizer bar.
• Z60 High-Performance employs monotube shocks, a 36 mm front stabilizer
bar and a sporty lowered ride height.
• Z71 Off-road with 46 mm monotube shock absorbers, off-road jounce
bumpers and a heavy-duty 36 mm front stabilizer; also includes a high
capacity air cleaner, skid plates, locking differential and Z71 decals.
COIL-OVER-SHOCK FRONT SUSpENSION
Sierra 1500’s coil-over-shock suspension reduces unsprung weight, resulting
in improved handling and a smoother ride in all conditions.
* Maintenance needs vary with different uses and driving conditions. Please refer to the vehicle Owner’s
Manual for more information.
