Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take the vehicle to your dealer/
retailer service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at your dealer/
retailer service department. Contact your dealer/retailer
for additional information or the procedure can be found
in the service manual. To purchase a service manual,
see Service Publications Ordering Information
on
page 8‑16.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑10. Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 7‑3, and be sure
to use the fluid listed in Recommended Fluids and
Lubricants on page 7‑10.
Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to your
dealer/retailer service department and have it repaired
as soon as possible. See Recommended Fluids and
Lubricants
on page 7‑10for the proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding fluid
will not correct a leak. A fluid loss in this system could
indicate a problem. Have the system inspected and
repaired.
6-31

When to Check and What to Use
The hydraulic clutch fluid
reservoir cap has this
symbol on it. See Engine
Compartment Overview
on page 6‑14for
reservoir location.
Refer to the Maintenance Schedule for the proper
fluid to use. See Recommended Fluids and Lubricants
on page 7‑10. The fluid requires changing every
two years. See Scheduled Maintenance on page 7‑3.
How to Check and Add Fluid
Visually check the clutch fluid reservoir to make sure
the fluid level is at the MIN (minimum) line on the side
of the reservoir. The hydraulic clutch fluid system
should be closed and sealed.
Do not remove the cap to check the fluid level or to
top‐off the fluid level. Remove the cap only when
necessary to add the proper fluid until the level
reaches the MIN line.
Cooling System (Engine)
The cooling system allows the engine to maintain the
correct working temperature.

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.
Refer to the Maintenance Schedule to determine when
to check the brake fluid. See Scheduled Maintenance
on page 7‑3.
Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir.
See Engine Compartment Overview on page 6‑14.
The fluid level should be above the MIN mark on the
reservoir. If it is not, have the brake hydraulic system
checked to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the level is between the MIN and MAX marks.
What to Add
Use only new DOT 3 brake fluid from a sealed
container. See Recommended Fluids and Lubricantson
page 7‑10.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This helps keep dirt
from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.

Windshield Replacement
The windshield is part of the Head-Up Display (HUD)
system. If you ever have to get the windshield replaced,
get one that is designed for HUD or the HUD image
may look out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for wear
and cracking. See Scheduled Maintenanceon
page 7‑3for more information.
Replacement blades come in different types and are
removed in different ways. For the proper type and
length, see Maintenance Replacement Parts
on
page 7‑12. It is a good idea to clean or replace the wiper blade
assembly every six months. Allowing the wiper blade
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's
warranty. Do not allow the wiper blade arm to touch
the windshield.
To remove the wiper blade assembly:
1. Open the hood to gain access to the windshield wipers.
2. Lift the wiper arm away from the windshield.
6-59

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 fuel 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 reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will continue
upon subsequent vehicle start‐ups as long as the
malfunction exists. When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle
to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly on your
vehicle. The TPMS sensors monitor the air pressure
in the vehicle's tires and transmits the tire pressure
readings to a receiver located in the vehicle.
When a low tire pressure
condition is detected,
the TPMS illuminates
the low tire pressure
warning light, located
in the instrument panel
cluster.
At the same time a message to check the pressure in a
specific tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and
the DIC warning message appear at each ignition
cycle until the tires are inflated to the correct inflation
pressure. Using the DIC, tire pressure levels can be
viewed by the driver. For additional information and
details about the DIC operation and displays see DIC
Operation and Displays
on page 4‑47and DIC
Warnings and Messages on page 4‑52. The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. See
Loading the
Vehicle
on page 5‑28, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also see Inflation - Tire Pressure
on page 6‑70for additional information.
Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation
on
page 6‑76, When It Is Time for New Tireson
page 6‑76, and Tires on page 6‑62.
Notice: Liquid tire sealants could damage the
Tire Pressure Monitor System (TPMS) sensors.
Sensor damage caused by using a tire sealant is
not covered by your warranty. Do not use liquid
tire sealants.
6-74

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires for signs of wear or damage Also
check for damaged wheels. See When It Is Time
for New Tires
on page 6‑76and Wheel
Replacement
on page 6‑81.
The tires on your vehicle are different sizes front
to rear. Due to this, the tires should not be rotated.
Each tire and wheel should be used only in the
position it is in.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
6-76

You need a new tire if any of the following statements
are true:
.You can see the indicators at three or more places
around the tire.
.You can see cord or fabric showing through the
tire's rubber.
.The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
.The tire has a bump, bulge or split.
.The tire has a puncture, cut or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they
are not being used. This is also true for the spare tire,
if your vehicle has one. Multiple conditions affect how
fast this aging takes place, including temperatures,
loading conditions, and inflation pressure maintenance.
With proper care and maintenance tires will typically
wear out before they degrade due to age. If you are
unsure about the need to replace your tires as they get
older, consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specific tires for your
vehicle. The original equipment tires installed on your
vehicle, when it was new, were designed to meet
General Motors Tire Performance Criteria Specification
(TPC Spec) system rating. If you need replacement
tires, GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle will
continue to have tires that are designed to give the
same performance and vehicle safety, during normal
use, as the original tires.
GM's exclusive TPC Spec system considers over a
dozen critical specifications that impact the overall
performance of your vehicle, including brake system
performance, ride and handling, traction control, and
tire pressure monitoring performance. GM's TPC Spec
number is molded onto the tire's sidewall near the tire
size. If the tires have an all‐season tread design, the
TPC Spec number will be followed by an MS for mud
and snow. See Tire Sidewall Labeling
on page 6‑64,
for additional information.

cleaners with acid, or abrasive cleaning brushes on
them because they could damage the surface. Do not
use chrome polish on aluminum wheels.
Notice: Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not be
covered by the vehicle warranty. Use chrome polish
on chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
Notice: Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the vehicle warranty. Never drive a
vehicle that has aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice: Using petroleum-based tire dressing
products on the vehicle may damage the paint finish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces on
the vehicle.
Finish Damage
Any stone chips, fractures or deep scratches in the
finish should be repaired right away. Bare metal will
corrode quickly and may develop into major repair
expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer/retailer.
Larger areas of finish damage can be corrected in your
dealer's/retailer's body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, floor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close areas
of the frame should be loosened before being flushed.
Your dealer/retailer or an underbody car washing
system can do this.
