2004 JEEP GRAND CHEROKEE ABS

4. Reset the transmitter by pressing the ªUnlockº button
six times. Test the transmitter operation.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors, liftgate, liftgate
flipper glass, and ignition for unauthorized operation.
When the alarm is activated, the system provides both
audible and visual signals. The horn will sound repeat-
edly for three minutes and the headlights and taillights
will flash for an additional 15 minutes.
To Set the Alarm
The alarm will set when you use the remote keyless entry
transmitter to lock the doors and liftgate or when you use
the power door lock switch while the door is open. After
all the doors are locked and closed, a red light on top of
the instrument panel will flash rapidly for about 16
seconds to signal that the system is arming. During this
16 second pre-arm period, opening any door or theliftgate will cancel the arming. If the system successfully
arms, the red light will flash at a slower rate to indicate
the alarm is set.
To Disarm the System
To disarm the system, use the remote keyless entry
transmitter or the key to unlock the driver's door. If
something has triggered the system in your absence, the
horn will sound three times when you unlock the doors.
Check the vehicle for tampering.
The Security Alarm System is designed to protect your
vehicle; however, you can create conditions where the
system will arm unexpectedly. If you remain in the
vehicle and lock the doors with the transmitter, once the
system is armed (after 16 seconds), when you pull the
door handle to exit the alarm will sound. If this occurs,
press the ªUnlockº button on the remote keyless entry
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 23

18. Seat Belt Indicator Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 seconds as a bulb check.
During the bulb check, if the driver's seat belt is
unbuckled, a chime will sound. After the bulb check or
when driving, if the driver seat belt remains unbuckled,
the Seat Belt Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertŸ)9in the Occupant Restraints
section for more information.
19. Anti-Lock Warning Light
The amber ABS warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on during
starting, have the bulb repaired promptly. This light also
illuminates to indicate that the Antilock Brake System
self-check is in process at vehicle start-up.If the light remains on after start-up, or comes on and
stays on at road speeds, it may indicate that the ABS has
detected a malfunction or has become inoperative. In this
case, the system reverts to standard non-antilock brakes.
Turn the engine off and on again to reset the Antilock
Brake System. If the light remains on, see your autho-
rized dealer. If both the red BRAKE and amber ABS
warning lights are on, see your authorized dealer imme-
diately.
20. Fuel Gage
The pointer shows the level of fuel in the fuel tank when
the ignition key is in the ON position. A small arrow
indicates the side of the vehicle where the filler cap (gas
cap) is located.

ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
WARNING!
Significant over or under inflation of tires, or mixing
sizes of tires or wheels on the vehicle 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.

WARNING!
²Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
²The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
²The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
CAUTION!
The Anti-Lock Brake System is subject to possible
detrimental effects of electronic interference caused
by improperly installed after-market radios or tele-
phones.
NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the Anti-Lock Brake
System is functioning.
WARNING!
To use your brakes and accelerator more safely,

TIRE SAFETY INFORMATION
Tire Markings
NOTE:
²P(Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter ªPº molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
²European Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter9P9is absent from this tire
size designation. Example: 215/65R15 96H
²LT(Light Truck)-Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters ªLTº that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
²Temporary Spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter ªTº
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
²High Flotation tire sizing is based on U.S. design
standards and begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.
