It cannot be reset
accurately until the next oil
change.
The oil life system can also be
reset as follows: 1. Display REMAINING OIL LIFE on the DIC. See Driver
Information Center (DIC)
0139.
2. Fully press and release the accelerator pedal three
times within five seconds.
If the CHANGE ENGINE
OIL SOON message is not
on, the system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL
SOON message comes back
on when the vehicle is started,
the engine oil life system has
not been reset. Repeat the
procedure.Automatic
Transmission Fluid
A transmission fluid leak is the
only reason for fluid loss. If a
leak occurs, take the vehicle to
your dealer and have it
repaired as soon as possible.
Caution
Use of the incorrect
automatic transmission fluid
may damage the vehicle, and
the damage may not be
covered by the vehicle
warranty. Always use the
correct automatic
transmission fluid. See
Recommended Fluids and
Lubricants 0433.
See your dealer to have the
fluid and filter changed at the
intervals listed in the
Maintenance Schedule 0429.
Engine Air Filter Life
System
If equipped, this feature
provides the engine air filter’s
remaining life and best timing
for a change. The timing to
change an engine air filter
depends on driving and
environmental conditions.
When to Change the
Engine Air Filter
When the Driver Information
Center (DIC) displays a
message to replace the engine
air filter at the next oil change,
follow this timing.
When the DIC displays a
message to replace the engine
air filter soon, replace the
engine air filter at the earliest
convenience.
The system must be reset
after the engine air filter is
changed.
If the DIC displays a message
to check the engine air filter
system, see your dealer.

{Warning
An underhood electric fan
can start up even when the
engine is not running and
can cause injury. Keep
hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or
radiator hoses, or other
engine parts. They can be
very hot and can burn you.
Do not run the engine if
there is a leak; all coolant
could leak out. That could
cause an engine fire and can
burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The engine cooling system in
the vehicle is filled with
DEX-COOL engine coolant
mixture. This coolant needs to
be checked and changed at
appropriate levels. See
Recommended Fluids and
Lubricants 0433 and
Maintenance Schedule 0429.
The following explains the
cooling system and how to
check and add coolant when it
is low. If there is a problem
with engine overheating, see
Engine Overheating 0356.

damaged. Add brake fluid
only when work is done on
the brake hydraulic system.
When the brake fluid falls to a
low level, the brake warning
light comes on. See Brake
System Warning Light 0131.
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
0 429.
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0433.
{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 on the original battery
label when a new battery is
needed. For replacement of
the battery, see your dealer.
The vehicle has an Absorbent
Glass Mat (AGM) 12-volt
battery. Installation of a
standard 12-volt battery will
result in reduced 12-volt
battery life.
When using a 12-volt battery
charger on the 12-volt AGM
battery, some chargers have
an AGM battery setting on the
charger. If available, use the
AGM setting on the charger,
to limit charge voltage to
14.8 volts.

unusual noise. If required, have
the transfer case serviced by
your dealer.
Park Brake and
P (Park) Mechanism
Check
{Warning
When you are doing this
check, the vehicle could
begin to move. You or
others could be injured and
property could be damaged.
Make sure there is room in
front of the vehicle in case it
begins to roll. Be ready to
apply the regular brake at
once should the vehicle
begin to move.
Park on a fairly steep hill, with
the vehicle facing downhill.
Keeping your foot on the
regular brake, set the parking
brake.
.To check the parking brake's
holding ability: With the
engine running and the
transmission in N (Neutral),
slowly remove foot pressure
from the regular brake pedal.

Do this until the vehicle is
held by the parking
brake only.
.To check the P (Park)
mechanism's holding ability:
With the engine running,
shift to P (Park). Then
release the parking brake
followed by the regular
brake.
Contact your dealer if service
is required.
Wiper Blade
Replacement
Windshield wiper blades
should be inspected for wear
or cracking.
It is a good idea to clean or
replace the wiper blade
assembly on a regular basis or
when worn. For proper
windshield wiper blade length
and type, see Maintenance
Replacement Parts 0434.
Caution
Allowing the wiper arm to
touch the windshield when
no wiper blade is installed
could damage the
windshield. Any damage that
occurs would not be
covered by the vehicle
warranty. Do not allow the
wiper arm to touch the
windshield.
Front Wiper Blade
Replacement
To replace the wiper blade
assembly:
1. Pull the windshield wiper assembly away from the
windshield.
2. Lift up on the latch in themiddle of the wiper blade
where the wiper arm
attaches.
3. With the latch open, pull the wiper blade down
toward the windshield far
enough to release it from
the J-hooked end of the
wiper arm.
4. Remove the wiper blade.
5. Reverse Steps 1–3 for wiper blade replacement.

liftgate system in full open
position.
{Warning
If the gas struts that hold
open the hood, trunk, and/or
liftgate fail, you or others
could be seriously injured.
Take the vehicle to your
dealer for service
immediately. Visually inspect
the gas struts for signs of
wear, cracks, or other
damage periodically. Check
to make sure the hood/
trunk/liftgate is held open
with enough force. If struts
are failing to hold the hood/
trunk/liftgate, do not
operate. Have the vehicle
serviced.
Caution
Do not apply tape or hang
any objects from gas struts.
Also do not push down or
pull on gas struts. This may
cause damage to the
vehicle.

High Speed Operation Inflation Pressures
Tire Size Cold Inflation Pressure kPa (psi)
235/65R18 300 kPa (44 psi)
235/55R20 300 kPa (44 psi)
Return the tires to the
recommended cold tire
inflation pressure when
high-speed driving has ended.
See Vehicle Load Limits 0247
and Tire Pressure 0384.
Tire Pressure Monitor
System
The Tire Pressure Monitor
System (TPMS) uses radio and
sensor technology to check
tire pressure levels. The TPMS
sensors monitor the air
pressure in your tires and
transmit tire pressure
readings to a receiver located
in the vehicle.
Each tire, including the spare
(if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the
vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle
has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label, you should
determine the proper tire
inflation pressure for those
tires.)
As an added safety feature,
your vehicle has been
equipped with a tire pressure
monitoring system (TPMS)
that illuminates a low tire
pressure telltale when one or
more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates,
you should stop and check
your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat
and can lead to tire failure.
Under-inflation also reduces
energy efficiency and tire
tread life, and may affect the
vehicle's handling and
stopping ability.
Please note that the TPMS is
not a substitute for proper tire
maintenance, and it is the
driver's responsibility to
maintain correct tire pressure,
even if under-inflation has not
