Brakes
Brake Fluid
The brake master cylinder
reservoir is filled with
DOT 3 brake fluid. See
Engine Compartment
Overview
on page 7‑14for the location of the
reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down:
.The brake fluid level goes down because of normal
brake lining wear. When new linings are installed,
the fluid level goes back up.
.A fluid leak in the brake hydraulic system can also
cause a low fluid level. Have the brake hydraulic
system fixed, since a leak means that sooner or
later the brakes will not work well. Do not top off the brake 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 brake fluid, as
necessary, only when work is done on the brake
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 hydraulic system.
See
“Checking Brake Fluid” in this section.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4‑31.
Refer to the Maintenance Schedule to determine when
to check the brake fluid. See Scheduled Maintenance
on page 8‑3.

All-Wheel Drive
Transfer Case
If your vehicle is equipped with All-Wheel Drive, be sure
to perform the lubricant checks described in this
section. There are two additional systems that need
lubrication.
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. SeeScheduled
Maintenance on page 8‑3.
How to Check Lubricant
(A) Drain Plug (B) Filler Plug
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the filler plug hole,
located on the transfer case, you'll need to add some
lubricant. Add enough lubricant to raise the level to
the bottom of the filler plug hole. Use care not to
overtighten the plug.
7-47

What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids and
Lubricants on page 8‑10.
Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle fluid
unless you suspect there is a leak or you hear an
unusual noise. A fluid loss could indicate a problem.
Have it inspected and repaired.
All axle assemblies are filled by volume of fluid during
production. They are not filled to reach a certain level.
When checking the fluid level on any axle, variations in
the readings can be caused by factory fill differences
between the minimum and the maximum fluid volume.
Also, if a vehicle has just been driven before checking
the fluid level, it may appear lower than normal because
fluid has traveled out along the axle tubes and has not
drained back to the sump area. Therefore, a reading
taken five minutes after the vehicle has been driven will
appear to have a lower fluid level than a vehicle that
has been stationary for an hour or two. Remember that
the rear axle assembly must be supported to get a true
reading.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
The proper level is from 0.04 inch to 0.75 inch (1.0 mm
to 19.0 mm) below the bottom of the filler plug hole,
located on the rear axle. Add only enough fluid to reach
the proper level.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See Recommended Fluids and
Lubricants on page 8‑10.

What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids and
Lubricants on page 8‑10.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps may be affected and adjustment may
be necessary.
If oncoming vehicles flash their high beams at you, this
may mean the vertical aim of your headlamps needs to
be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to be
adjusted. It is possible however, to re-aim the
headlamps as described. The vehicle should:
.Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall or other flat surface.
.Have all four tires on a level surface which is level
all the way to the wall or other flat surface.
.Be placed so it is perpendicular to the wall or other
flat surface.
.Not have any snow, ice, or mud on it.
.Be fully assembled and all other work stopped
while headlamp aiming is being performed.
.Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
.Have the tires properly inflated.
.Have the spare tire is in its proper location in the
vehicle.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
or cracking. SeeScheduled Maintenance on page 8‑3.
Replacement blades come in different types and are
removed in different ways. To replace the wiper blade
assembly, do the following: 1. Pull the windshield wiper arm connector away from the windshield.
2. Squeeze the grooved areas on each side of the
blade, and rotate the blade assembly away from
the arm connector.
3. Install the new blade onto the arm connector andmake sure the grooved areas are fully set in the
locked position.
For the proper type and size, see Maintenance
Replacement Parts on page 8‑12.

8. Proceed to the driver side rear tire, and repeat theprocedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active.
The TIRE LEARNING ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. See When It Is Time for New
Tires
on page 7‑71for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). See Scheduled Maintenance
on page 8‑3.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform
most like it did when the tires were new. Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or
wheels. See
When It Is Time for New Tires
on
page 7‑71
and Wheel Replacementon page 7‑76.
When rotating your vehicle's tires, always use the
correct rotation pattern shown here.
Do not include the spare tire in the tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. See Inflation - Tire
Pressure
on page 7‑64and Loading the Vehicleon
page 6‑32

Maintenance Schedule
Introduction
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Proper vehicle maintenance helps to keep the vehicle in
good working condition, improves fuel economy, and
reduces vehicle emissions for better air quality.
Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need
more frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer/retailer. The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See
Loading the Vehicle on page 6‑32.
.are driven on reasonable road surfaces within legal
driving limits.
.are driven off‐road in the recommended manner.
SeeOff-Road Driving on page 6‑13.
.use the recommended fuel. See Gasoline Octaneon page 7‑7.
{WARNING:
Performing maintenance work on a vehicle can be
dangerous. In trying to do some jobs, you can be
seriously injured. Do your own maintenance work
only if you have the required know-how and the
proper tools and equipment for the job. If you
have any doubt, see your dealer/retailer to have a
qualified technician do the work. See Doing Your
Own Service Work on page 7‑5.
8-2

At your General Motors dealer/retailer, you can be
certain that you will receive the highest level of service
available. Your dealer/retailer has specially trained
service technicians, uses genuine GM replacement
parts, as well as, up to date tools and equipment to
ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 8‑10andMaintenance Replacement Partson
page 8‑12. We recommend the use of genuine parts
from your dealer/retailer.
Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 7‑70.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 7‑15. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset.
Your dealer/retailer has trained service technicians
who will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 7‑18.
When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
