2005 JEEP GRAND CHEROKEE tire pressure reset

12. Tire Pressure Monitor Warning Light
This light will turn on continuously when there
is a low tire pressure condition. The light will
also turn on if a problem exists with any tire
sensor. When a system fault is detected, the
indicator lamp will flash repetitively for ten seconds. The
flash cycle will repeat every ten minutes or until the fault
condition is removed and reset. The light will remain on
or flashing until the tire pressure is properly set or the
problem with the sensor is corrected.
This light will turn on momentarily as a bulb check when
the engine is started.
When the tire pressure monitoring system warning light
is lit, one or more of your tires is significantly underin-
flated. You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the tire and loading information placard.
Driving on a significantly underinflated tire causes thetire to overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
Each tire, including the spare, should be checked
monthly when cold and set to the recommended inflation
pressure as specified in the tire and loading information
placard. (See page 269 for more information.)
13. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

Tire Pressure Display — If Equipped
Shows the current pressure of all 4 road tires.
NOTE:Tires heat up during normal driving conditions.
Heat will cause the tire pressure to increase from 2 to 6
psi (14 to 41 kPa) during normal driving conditions. Refer
to “Tire Inflation Pressures” in Section 5 for additional
information.
Miles to Service
Shows the distance remaining to require service.
NOTE:This display can be reset to the set service
interval by pressing and holding the RESET button for 3
seconds.
Blank Screen
Shows a blank screen. Pressing the C/T button returns to
the compass/temperature display.
Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
After completing one 360 degree turn, with the vehicle
traveling less than 5 mph (8 km/h), in an area free from
large metal or metallic objects, the CAL symbol will turn
off and the compass will function normally.

Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your dealer
for proper diagnosis of the problem.
Improper alignment will not normally cause vehicle
vibration, which may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.
TIRE PRESSURE MONITOR SYSTEM
Tire Pressure Monitoring — Base System
The Tire Pressure Monitor System (TPM) system uses
wireless technology with wheel rim mounted electronic
sensors to monitor tire pressure levels. Sensors, mounted
to each wheel as part of the valve stem, transmit tire
pressure readings to the Receiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.The “Tire Pressure Monitoring Indicator Lamp”
will illuminate in the instrument cluster, and an
audible chime will be activated when one or more
tire pressures is low. The “Tire Pressure Monitoring
Indicator Lamp” will flash on and off for ten seconds
when a system fault is detected. The flash cycle will
repeat every ten minutes or until the fault condition is
removed and reset.
The Tire Pressure Monitoring System consists of the
following components:•Receiver Module
•5 Wheel Sensors (including Full Size Spare Tire)
•Amber Colored Tire Pressure Monitoring Indicator
Lamp
The system will consist of tire pressure monitoring
sensors attached to each wheel through the valve stem
mounting hole, a central receiver module and an amber

when a system fault is detected. The flash cycle will
repeat every ten minutes or until the fault condition is
removed and reset.
The Tire Pressure Monitoring System consists of the
following components:
•Receiver Module
•5 Wheel Sensors (including Full Size Spare Tire)
•4 Wheel Sensor Trigger Modules
•Tire Pressure Monitoring System Display Messages in
the EVIC
•Amber Colored Tire Pressure Monitoring Indicator
Lamp
The system consists of tire pressure monitoring sensors
attached to each wheel through the valve stem mounting
hole, a central receiver module, Wheel Sensor Trigger
Modules mounted in three of the four wheel wells,various Tire Pressure Monitoring System Display Mes-
sages in the EVIC, and an amber colored Indicator Lamp.
A sensor shall be installed in the spare wheel if the
vehicle is equipped with a matching full size spare wheel
and tire assembly.
NOTE:For vehicles with optional wheel/tire sizes and
significantly different tire placard pressures, the placard
pressure value and the low-pressure threshold value is
re-programmable at your authorized dealer to accommo-
date the customer selected wheel/tire combinations rec-
ommended by DaimlerChrysler Corporation.
The followingwarningswill cause a text message to be
displayed, an audible chime to sound and the “Tire
Pressure Indicator Lamp” to illuminate. The audible
chime will occur once every ignition cycle for each
warningdetected. The “Tire Pressure Indicator Lamp”
272 STARTING AND OPERATING

will illuminate continuously (solid) and shall remain
illuminated until the warning condition is removed/
reset.
NOTE:The Indicator Lamp will only illuminate for the
four active road tires. A low spare tire pressure will not
cause the Indicator Lamp to illuminate
When the appropriate conditions exist, the Electronic
Vehicle Information Center (EVIC) displays the following
messages.
LEFT FRONT, LEFT REAR, RIGHT FRONT,
RIGHT REAR, SPARE LOW PRESSURE
One or more of these messages will be displayed in the
EVIC if a low tire pressure condition exists in one or more
tires.Inspect all tires for proper inflation pressure, once the
proper tire pressure has been set, the TPM system
warning will reset automatically when the vehicle has
been driven for at least 2 minutes at or above 15 mph (24
km/h).
CHECK TPM SYSTEM
See your authorized dealer when this message appears in
the EVIC. This message indicates that a system fault
condition has been detected.
