2010 JEEP GRAND CHEROKEE brake fluid

Airbag Warning Light
The light should come on and remain on for six to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objectslodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 73

INSTRUMENT CLUSTER DESCRIPTIONS
1. Speedometer
Indicates vehicle speed.
2. Brake Warning LightThis light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Program (ESP) sys-
tem. In this case, the light will remain on until the
condition has been corrected. If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during
each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

236 STARTING AND OPERATING

WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK position.
The parking brake lever is located in the center console.
To apply the parking brake, pull the lever up as firmly as possible. To release the parking brake, pull the lever up
slightly, press the center button, then lower the lever
completely.
When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.
Parking Brake
250 STARTING AND OPERATING

WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in an
accident.
Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, use
the AutoStickfeature (D-) to select a lower gear range.
NOTE: Using a lower gear range while operating the
vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
