VEHICLE CARE 353
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 4 brake fluid as indicated on the
reservoir cap. SeeEngine Compartment
Overview 0331 for the location of the
reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake applied
if equipped with a manual
transmission. On a level surface, the
brake fluid level should be between
the minimum and maximum marks
on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.
.A fluid leak in the brake/clutch
hydraulic system. Have the brake/
clutch hydraulic system fixed. With
a leak, the brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it. 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 0108.
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 0410. What to Add
Use only GM approved DOT 4 brake
fluid from a clean, sealed container.
See
Recommended Fluids and
Lubricants 0420.
{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.

VEHICLE CARE 355
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.
.Automatic transmission vehicles
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 0421.
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.
To replace the wiper blade assembly: 1. Pull the windshield wiper assembly away from the windshield. The
passenger side wiper arm has
limited travel.
2. Lift up on the latch in the middleof 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.
Windshield Replacement
HUD System
The windshield is part of the HUD
system. If the windshield needs to be
replaced, a GM replacement
windshield is recommended. The
replacement windshield must be
installed according to GM
specifications for proper alignment.
If it is not, the HUD image may look
out of focus.
Driver Assistance Systems
If the windshield needs to be replaced
and the vehicle is equipped with a
front camera sensor for the Driver
Assistance Systems, a GM

damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the vehicle in P (Park) with an
automatic transmission, or Neutral

Caution
The vehicle may be equipped with
an electric parking brake and/or an
electronic shifter. In the event of a
loss of 12-volt battery power, the
electric parking brake cannot be
released, and the vehicle cannot be
shifted to N (Neutral). Tire skates
or dollies must be used under the
non-rolling tires to prevent damage
while loading/unloading the vehicle.
Dragging the vehicle will cause
damage not covered by the vehicle
warranty.
Caution
The vehicle may be equipped with a
tow eye. Improper use of the tow
eye may cause damage to the
vehicle and is not covered by the
vehicle warranty. If equipped, use
the tow eye to load the vehicle onto
a flatbed tow truck from a flat road
surface, or to move the vehicle a
very short distance at a walking
pace. The tow eye is not designed(Continued)
Caution (Continued)
for off-road recovery. The vehicle
must be in N (Neutral) with the
electric parking brake released
when using the tow eye.
Contact a professional towing service
if the disabled vehicle must be
transported. GM recommends a
flatbed tow truck to transport a
disabled vehicle. Use ramps to help
reduce approach angles, if necessary.
If equipped, a tow eye may be located
near the spare tire or emergency jack.
Do not use the tow eye to pull the
vehicle from the snow, mud, sand,
or ditch. Tow eye threads may have
right or left-hand threads. Use caution
when installing or removing the
tow eye. The vehicle must be in N (Neutral)
and the electric parking brake must be
released when loading the vehicle
onto a flatbed tow truck.
.If the vehicle is equipped with car
wash mode and has 12-volt battery
power, refer to
“Car Wash Mode ”
under Automatic Transmission 0246
to place the vehicle in N (Neutral).
.If the 12-volt battery is dead and/or
the engine will not start, the vehicle
will not move. Try to jump start the
vehicle. Refer to Jump Starting -
North America 0394 and if the
jump start is successful, retry the
“Car Wash Mode ”procedure.
.If jump starting is unsuccessful, the
vehicle will not move. Tire skates or
dollies must be used under the
non-rolling tires to prevent vehicle
damage.
