2007 JEEP GRAND CHEROKEE brake light

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the ªBrake Warning Lightº in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE:The instrument cluster ªBrake Warning Lightº
indicates only that the parking brake is applied. It does
not indicate the degree of brake application.
Be sure the parking brake is firmly set when parked and
the gear shift lever is in the P (Park) position. When
parking on a hill, you should apply the parking brake
before placing the gear shift lever in P (Park), otherwise
the load on the transmission locking mechanism may
make it difficult to move the selector out of P (Park).
Parking Brake
244 STARTING AND OPERATING

WARNING!
Significant over or under inflation of tires can lead
to loss of braking effectiveness.
The Anti-Lock Brake System conducts a low-speed self-
test at about 12 mph (20 km/h). If you have your foot
lightly on the brake while this test is occurring you may
feel slight pedal movement. The movement can be more
apparent on ice and snow. This is normal.
The Anti-Lock Brake System pump motor runs during
the self-test at 12 mph (20 km/h) and during an ABS stop.
The pump motor makes a low humming noise during
operation, which is normal.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
246 STARTING AND OPERATING

WARNING!
Do not connect trailer brakes to your vehicle's hy-
draulic brake lines. It can overload your brake sys-
tem 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 dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements Ð Trailer Lights & Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may includea4and7pin
wiring harness. Use a factory approved trailer harness
and connector.The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

298 MAINTAINING YOUR VEHICLE

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE:Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before a hose is
replaced based on leakage.
NOTE:Inspection of brake hoses should be performed
whenever the brake system is serviced and at every
engine oil change. Inspect hydraulic brake hoses for
surface cracking, scuffing, or worn spots. If there is any
evidence of cracking, scuffing, or worn spots, the hoseshould be replaced immediately! Eventual deterioration
of the hose can take place resulting in a possibility of a
burst failure.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Fluid Level Check
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning light indicates system failure.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
ªFULLº mark on the side of the master cylinder reservoir.

Once a Month
²Check the tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of the coolant reservoir, brake
master cylinder, and add as needed.
²Check all lights and all other electrical items for correct
operation.At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect brake hoses.
²Check the engine coolant/anti-freeze level, hoses, and
clamps.
