2016 JEEP CHEROKEE warning light

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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light 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 willTire Pressure Monitoring Low Pressure Warning
5
STARTING AND OPERATING 573

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
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 to
facilities 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.
Tire Pressure Monitoring Service Warning
574 STARTING AND OPERATING

Vehicles With Matching Full-Size Spare
1. The matching full size spare wheel and tire assemblyhas 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
message, 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. 4. The EVIC/DID will display a graphic showing the tire
pressure 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
5
STARTING AND OPERATING 575

graphic in the EVIC/DID will still display a different
color pressure value and anInflate 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/DID 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.

•If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
•
Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
