2004 JEEP GRAND CHEROKEE sensor

and display SPARE SWAP DETECTED along with a
chime. This could take up to 10 minutes with vehicle
speed above 25 mph (40 km/h).
With the 4 Tire TPM System, if a road tire and wheel is
replaced by the spare, the TPM system will display TIRE
SENSOR BAD/MISSING. This is due to the spare tire not
being equipped with a tire pressure sensor. Once the road
tire is repaired and/or installed back on the vehicle with
the proper tire pressure the message will be removed.
This could take up to 10 minutes with vehicle speed
above 25 mph (40 km/h).
The tire pressure sensorsmustbe retrained following a
wheel rotation or sensor replacement. Refer to ªEVIC Ð
Retrain Tire Sensorsº in Section 3 for more information. It
is necessary to program the EVIC with the new sensor(s)
or the new position of each sensor as it is rotated to a
different corner of the vehicle.If a wheel rotation is not followed by the retrain proce-
dure, the system will not properly inform you of the
correct vehicle location of a low or high tire pressure.

CAUTION!
²Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.

fluid will leak from the transfer case and damage
internal parts.
SNOW PLOW
Snow plows, winches, and other aftermarket equipment
shouldnotbe added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpect-
edly or could fail to deploy during a collision.

aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.
234 STARTING AND OPERATING

attention should also be given to hood latching compo-
nents to insure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as MopartLock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner to remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.Avoid using the wiper blades to wipe frost or ice from the
windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers Ð Front and Rear
On vehicles equipped with a Vehicle Information Center,
the low washer fluid level will be indicated. When the
sensor detects a low fluid level, the windshield will light
on the vehicle graphic outline and the ªWasher Fluid
Lowº message will be displayed.
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
