.Allow greater following
distance and watch for
slippery spots. Icy patches
can occur on otherwise clear
roads in shaded areas. The
surface of a curve or an
overpass can remain icy
when the surrounding roads
are clear. Avoid sudden
steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice

Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. If possible, use

be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.

Drive Systems
All-Wheel Drive
Vehicles with this feature
always send engine power to
all four wheels. It is fully
automatic, and adjusts itself as
needed for road conditions.
Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is
pressed during the tests orwhen the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light
0128.
ABS does not change the time
needed to get a foot on the
brake pedal and does not
always decrease stopping
distance. If you get too close
to the vehicle ahead, there will not be enough time to apply
the brakes if that vehicle
suddenly slows or stops.
Always leave enough room
ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just
hold the brake pedal down
firmly. Hearing and feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and
braking at the same time. In
many emergencies, steering
can help even more than
braking.

the correct operation of the
EPB system, or at the request
of other safety functions that
utilize the EPB.
If the EPB fails to apply, block
the rear wheels to prevent
vehicle movement.
EPB Release
To release the EPB:1. Turn the ignition on or to accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
red parking brake status light
is off.
If the amber service parking
brake warning light is on,
release the EPB by pressing
and holding the EPB switch.
Continue to hold the switch
until the red parking brake
status light is off. If either light
stays on after release is
attempted, see your dealer.
Caution
Driving with the parking
brake on can overheat the
brake system and cause
premature wear or damage
to brake system parts. Make
sure that the parking brake
is fully released and the
brake warning light is off
before driving.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing
Tips 0365.
Automatic EPB Release
The EPB will automatically
release if the vehicle is
running, placed into gear, and
an attempt is made to drive
away. Avoid rapid acceleration
when the EPB is applied, to
preserve parking brake
lining life.
Brake Assist
Brake Assist detects rapid
brake pedal applications due
to emergency braking
situations and provides
additional braking to activate
the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to
activate ABS normally. Minor
noise, brake pedal pulsation,
and/or pedal movement during
this time may occur. Continue
to apply the brake pedal as
the driving situation dictates.
Brake Assist disengages when
the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA
feature. HSA does not
replace the need to pay
attention and drive safely.
You may not hear or feel
alerts or warnings provided
by this system. Failure to

Parking on Hills
{Warning
To prevent serious injury or
death, always park your
vehicle and trailer on a level
surface when possible.
When parking your vehicle and
your trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into
the curb if facing downhill
or into traffic if facing
uphill.
2. Have someone place chocks under the trailer
wheels. 3. When the wheel chocks
are in place, gradually
release the brake pedal to
allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking
brake and shift into
P (Park).
5. Release the brake pedal.
Leaving After Parking on
a Hill
1. Apply and hold the brake pedal.
.Start the engine.
.Shift into the
desired gear.
.Release the parking
brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance when Trailer
Towing
The vehicle needs service
more often when used to tow
trailers. See Maintenance
Schedule 0471. It is especially
important to check the
automatic transmission fluid,
engine oil, axle lubricant, belts,
cooling system, and brake
system before and during
each trip.
Check periodically that all nuts
and bolts on the trailer hitch
are tight.
Engine Cooling when
Trailer Towing
The cooling system may
temporarily overheat during
severe operating conditions.
See Engine Overheating
0 398.

Do not top off the brake/
clutch fluid. Adding fluid does
not correct a leak. If fluid is
added when the linings are
worn, there will be too much
fluid when new brake linings
are installed. Add or remove
fluid, as necessary, only when
work is done on the brake/
clutch hydraulic system.
{Warning
If too much brake fluid is
added, it can spill on the
engine and burn, if the
engine is hot enough. You or
others could be burned, and
the vehicle could be
damaged. Add brake fluid
only when work is done on
the brake/clutch hydraulic
system.
When the brake/clutch fluid
falls to a low level, the brake
warning light comes on. See
Brake System Warning Light
0 127. Brake fluid absorbs water over
time which degrades the
effectiveness of the brake
fluid. Replace brake fluid at the
specified intervals to prevent
increased stopping distance.
See Maintenance Schedule
0
471.
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0476.
{Warning
The wrong or contaminated
brake fluid could result in
damage to the brake
system. This could result in
the loss of braking leading to
a possible injury. Always use
the proper GM approved
brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Immediately wash
off any painted surface.
Battery - North
America
The original equipment battery
is maintenance free. Do not
remove the cap and do not
add fluid.
Refer to the replacement
number shown on the original
battery label when a new
battery is needed.
The vehicle has an Absorbed
Glass Mat (AGM) 12-volt
battery. Installation of a
standard 12-volt battery will
result in reduced 12-volt
battery life.
