Jeep Cherokee Operating Information Manual page 182

WARNING!
• Never use the PARK position on an auto-
matic transmission as a substitute for the
parking brake. Always apply the parking
brake fully when parked to guard against
vehicle movement and possible injury or
damage.
• When leaving the vehicle, always remove
the key fob from the ignition and lock your
vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allow-
ing children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally in-
jured. Children should be warned not to
touch the parking brake, brake pedal or the
shift lever.
• Do not leave the key fob in or near the
vehicle. A child could operate power win-
dows, other controls, or move the vehicle.

WARNING! (Continued)
• Always fully apply the parking brake when
leaving your vehicle or it may roll and cause
damage or injury. Also, be certain to leave
an automatic transmission in PARK, a
manual transmission in REVERSE or first
gear. Failure to do so may cause the ve-
hicle to roll and cause damage or injury.
CAUTION!
If the "Brake Warning Light" remains on with
the parking brake released, a brake system
malfunction is indicated. Have the brake sys-
tem serviced by an authorized dealer imme-
diately.
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
(Continued)
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 ABS 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 ABS 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.
