2014 JEEP CHEROKEE warning light

Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
will sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic Vehicle
Information Center (EVIC)/Driver information Display
(DID) will display a Tire Lowmessage for a minimum
of five seconds, an Inflate to XXmessage and a graphic
showing the pressure values of each tire with the low tire
pressure values in a different color.
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a
different color in the EVIC/DID graphic) to the vehicle’s
recommended cold placard pressure value as shown in
theInflate to XX message. Once the system receives the
updated tire pressures, the system will automatically

update, the pressure values in the graphic display in the
EVIC/DID will return to their original color, and the
“Tire Pressure Monitoring Telltale Light” will turn off.
The vehicle may need to be driven for up to 20 minutes
above 15.5 mph (25 km/h) in order for the TPMS to
receive this information.
SERVICE TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. The system fault
will also sound a chime. In addition, the EVIC/DID will
display aSERVICE TPM SYSTEM message for a mini-
mum of five seconds and then display dashes (- -) in
place of the pressure value to indicate which sensor is not
being received. If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “SERVICE TPM
Tire Pressure Monitoring Service Warning
516 STARTING AND OPERATING

SYSTEM” message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors. Vehicles With Matching Full-Size Spare
1. The matching full size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be
monitored by the TPMS.
2.
If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning
limit, a chime will sound and the “TPMS Telltale Light”
will turn on upon the next ignition key cycle. In
addition, the EVIC/DID will display a Tire Low mes-
sage, an Inflate to XX message and a graphic showing
the low tire pressure value in a different color.
3. After driving the vehicle for up to 20 minutes above 15.5 mph (25 km/h) the “TPMS Telltale Light” will
turn OFF, as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires.

STARTING AND OPERATING 517

4. The EVIC/DID will display a graphic showing the tirepressure value in the same color as the other pressure
values in place of the different color low tire pressure
value. The EVIC/DID will also display a “SPARE
LOW PRESSURE” message to remind you to service
the flat tire.
Vehicles With Compact Spare or Non-Matching Full
Size Spare
1. The compact spare tire or non-matching full size does not have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, the “TPMS Telltale Light” will
remain on and a chime will sound. In addition, the graphic in the EVIC/DID will still display a different
color pressure value and an
Inflate to XXmessage.
3. After driving the vehicle for up to 20 minutes above 15.5 mph (25 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid. In addition, the EVIC/DID will display a “SER-
VICE TPM SYSTEM” message for five seconds and
then display dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
EVIC/DID will display a “SERVICE TPM SYSTEM”
message for five seconds and then display dashes (- -)
in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare
or non-matching full size, the TPMS will update

automatically. In addition, the “TPMS Telltale Light”
will turn off and the graphic in the EVIC will display
a new pressure value instead of dashes (- -), as long as
no tire pressure is below the low-pressure warning
limit in any of the four active road tires. The vehicle
may need to be driven for up to 20 minutes above
15.5 mph (25 km/h) in order for the TPMS to receive
this information.

actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have a
collision.
• Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
