2010 GMC SIERRA DENALI steering wheel

Adding Equipment to Your
Airbag-Equipped Vehicle
Q: Is there anything I might add to or change aboutthe vehicle that could keep the airbags from
working properly?
A: Yes. If you add things that change the vehicle's
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, rollover sensor module, or airbag
wiring can affect the operation of the airbag system.
In addition, the vehicle may have a passenger
sensing system for the right front passenger
position, which includes sensors that are part of the
passenger seat. The passenger sensing system
may not operate properly if the original seat trim is
replaced with non-GM covers, upholstery or trim,
or with GM covers, upholstery or trim designed for a
different vehicle. Any object, such as an aftermarket
seat heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could
also interfere with the operation of the passenger
sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent
the passenger sensing system from properly turning
off the passenger airbag(s). See
Passenger Sensing
System on page 2‑66.
If you have any questions, call Customer
Assistance. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
See Customer Satisfaction Procedure on page 8‑2.
If the vehicle has rollover roof-rail airbags, see
Different Size Tires and Wheels
on page 6‑82for
additional important information.
Q: Because I have a disability, I have to get my vehicle modified. How can I find out whether this
will affect my airbag system?
A: If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 8‑2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal must
be applied. A (LOCK/OFF) :
This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch to
LOCK/OFF.
The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
Notice: Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
B (ACC/ACCESSORY) : This position lets things like
the radio and the windshield wipers operate while the
engine is off. Use this position if the vehicle must be
pushed or towed.

Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
With cruise control, a speed of about 40 km/h (25 mph)
or more can be maintained without keeping your foot on
the accelerator. Cruise control does not work at speeds
below about 40 km/h (25 mph).
When the brakes are applied, the cruise control
turns off.
If your vehicle has the Stabilitrak
®system and begins to
limit wheel spin while you are using cruise control, the
cruise control will automatically disengage. See
StabiliTrak
®Systemon page 5‑6. When road
conditions allow the cruise control to be safely used
again, it can be turned back on.
The cruise control buttons
are located on left side of
the steering wheel.
T(On/Off): Turn the system on and off. The indicator
light is on when cruise control is on and turns off when
cruise control is off.
+ RES (Resume/Accelerate) : This makes the vehicle
accelerate or resume to a previously set speed.
SET −(Set/Coast) : Sets the speed or makes the
vehicle decelerate.
[(Cancel): Cancels the cruise control without erasing
the set speed from memory.

Setting Cruise Control
Cruise control will not work if the parking brake is set,
or if the master cylinder brake fluid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to the
desired speed.
{WARNING:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Press
T.
2. Get up to the desired speed.
3. Press the SET− button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
If the brakes are applied while the cruise control is set,
the cruise control is disengaged. But it does not need to
be reset.
Once the vehicle speed reaches about 40 km/h
(25 mph) or more, press the +RES button on the
steering wheel. The vehicle will go back to the previous
set speed and stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
.Press and hold the +RES button on the steering
wheel until the new desired speed is reached, then
release it.
.To increase vehicle speed in small increments,
press the +RES button. Each time this is done, the
vehicle goes about 1.6 km/h (1 mph) faster.

Reducing Speed While Using Cruise
Control
To reduce the vehicle speed while using cruise control:
.Press and hold the SET–button on the steering
wheel until the desired lower speed is reached,
then release it.
.To slow down in very small amounts, press the
SET– button on the steering wheel briefly. Each
time this is done, the vehicle goes about 1.6 km/h
(1 mph) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle
speed. When you take your foot off the pedal, the
vehicle will slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle speed, load, and the steepness of the hills.
While going up steep hills, you might have to step on
the accelerator pedal to maintain the vehicle's speed.
While going downhill, you might have to brake or shift to
a lower gear to keep the vehicle's speed down. When
the brakes are applied the cruise control turns off.
Ending Cruise Control
There are three ways to end cruise control:
.Step lightly on the brake pedal.
.Press[on the steering wheel.
.PressTon the steering wheel.
