system. The system can be used
while the ignition is in ON/RUN or
ACC/ACCESSORY. The range of
the Bluetooth system can be up to
9.1 m (30 ft.). Not all phones support
all functions and not all phones work
with the Bluetooth system. See
www.gm.com/bluetooth for more

be turned off by turning the ignition
to ACC/ACCESSORY or
LOCK/OFF.
The rear window defogger can be
set to automatic operation, see
Climate and Air Quality under
Vehicle Personalization
on
page 4‑38. When auto rear defog is
selected, the rear window defogger
turns on automatically when the
interior temperature is cold and the
outside temperature is about 40°F
and below. The auto rear defogger
turns off automatically after about
10 minutes, or after 5 minutes if the
outside temperature is not as cold. For vehicles with heated outside
rearview mirrors, they turn on when

Driving and Operating 8-9
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Going down steep or long hills,
shift to a lower gear.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
.Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
.Top of hills: Be
alert—something could be in
your lane (stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.

8-18 Driving and Operating
Ignition Positions (Key
Access)
The ignition switch has four different
positions.
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. To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
A (LOCK/OFF):
This is the only
position from which the key can be
removed. This locks the ignition and
automatic transmission.
The shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
The ignition switch can bind in the
LOCK/OFF position 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 does not work,
then the vehicle needs service.
B (ACC/ACCESSORY) : This
position provides power to some of
the electrical accessories. It unlocks
the ignition. The transmission is
also unlocked in this position on
automatic transmission vehicles.
To move the key from ACC/
ACCESSORY to LOCK/OFF, the
shift lever must be in P (Park). C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the
ventilation fan and 12 volt power
outlet, as well as to display some
warning and indicator lights.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not restart if
the battery is allowed to drain for an
extended period of time.
D (START) : This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.

Driving and Operating 8-19
Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with push-button
start.
Pressing the button cycles it through
three positions, ACC/ACCESSORY,
ON/RUN/START and OFF.
The transmitter must be in the
vehicle for the system to operate.
If the push-button start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the keyless accesssystem. See
Remote Keyless Entry
(RKE) System Operation (Key
Access)
on page 1‑3or Remote
Keyless Entry (RKE) System
Operation (Keyless Access)
on
page 1‑5for more information.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN and the brake pedal must
be applied.
OFF: When this button is pressed
with the engine running, the engine
will be turned off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP)
on page 8‑20for
more information.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Driver Information Center (DIC)
on page 4‑25for more information. When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
ACC/ACCESSORY:
This position
allows you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied, will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
run down.
ON/RUN/START: This position is
for driving and starting. With the
ignition off, and the brake pedal
applied, pressing the button once
will place the ignition system in ON/
RUN/START. Once engine cranking
begins, release the button. Engine
cranking will continue until the
engine starts. See Starting the
Engine
on page 8‑20for more
information. The ignition will then
remain in ON/RUN.
