2006 JEEP GRAND CHEROKEE reset

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 Monitor System (TPMS) 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
•Tire Pressure Monitoring Telltale LightThe 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 a“Tire Pressure Monitoring
Telltale Light.”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“Ti re
Pressure Monitoring Telltale Light”to illuminate. The
audible chime will occur once every ignition cycle for
eachwarningdetected. The“Tire Pressure Monitoring
Telltale Light”will illuminate continuously (solid) and
shall remain illuminated until the warning condition is
removed/reset.
NOTE:The“Tire Pressure Monitoring Telltale Light”
will only illuminate for the four active road tires. A low
spare tire pressure will not cause the“Tire Pressure
Monitoring Telltale Light”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 TPMS 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.
298 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel cap
(gas cap). A poorly fitting cap could let impurities
into the fuel system. Also, a poorly fitting after-
market cap can cause the MIL (Malfunction Indica-
tor Light) to illuminate, due to fuel vapors escaping
from the system.
•Turn the engine off.
•Rotate the fuel cap to the left to remove.
•To replace the cap, insert it into the filler neck and
tighten the cap about 1/4 turn until you hear one click.
This is an indication that the cap is properly tightened.
•Make sure that the fuel cap tether strap is not caught
under the fuel cap.
CAUTION!
To avoid fuel spillage and overfilling, do not“top
off”the fuel tank after filling.
NOTE:When the fuel nozzle“clicks”or shuts off, the
fuel tank is full.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“CHECK GAS CAP”message will be displayed in the
EVIC (Electronic Vehicle Information Center). Refer to
“Electronic Vehicle Information Center”in Section 4 of this
manual. Tighten the fuel filler cap properly and press the
odometer reset button to turn the message off. If the
problem continues, the message will appear the next time
the vehicle is started. Refer to“Onboard Diagnostic System
—OBDII”in Section 7 of this manual for more information.

cap until aclickingsound is heard. This is an indication
that the gas cap is properly tightened. Press the odometer
reset button to turn the message off. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If
the problem is detected twice in a row, the system will
turn on the Malfunction Indicator Light (MIL). Resolving
the problem will turn the MIL light off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
