2013 JEEP WRANGLER display

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is “flashing” on the graphic
display to the vehicle’s recommended cold tire pressure
inflation value shown in the “Inflate to XX” message. Thesystem will automatically update, the graphic display of
the pressure value(s) will stop “flashing,” and the Tire
Pressure Monitoring Telltale Light will extinguish once
the updated tire pressure(s) have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
SERVICE TPM SYSTEM Warning
The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
The EVIC will display a “SERVICE TPM SYSTEM” mes-
sage for a minimum of five seconds. This message is then
followed by a graphic display, with “- -“ in place of the
pressure value(s), indicating which Tire Pressure Monitor-
ing Sensor(s) is not being received.

STARTING AND OPERATING 509

NOTE:Your system can be set to display pressure units
in PSI, kPa, or BAR.
If the ignition switch 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, the SERVICE TPM SYSTEMmessage will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM 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 TPM sensors.
The EVIC will also display a SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault is detected possibly related to an incorrect sensor
location fault. In this case, the SERVICE TPM SYSTEM
510 STARTING AND OPERATING

message is then followed by a graphic display, with
pressure values still shown. This indicates the pressure
values are still being received from the TPM Sensors but
they may not be located in the correct vehicle position.
However, the system still needs to be serviced as long as
theSERVICE TPM SYSTEM message exists.
NOTE:
•
If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, a chime to sound, a “LOW TIRE PRESSURE”
message to appear in the EVIC, and the graphic display
will still show the low tire pressure value “flashing.”
Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) will turn OFF the “Tire Pressure Monitoring
Telltale Light” as long as none of road tires are below the
low pressure warning threshold.
•
If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the “Tire Pressure
Monitoring Telltale Light” will remain ON, a chime
will sound, and the EVIC will still display a “flashing”
pressure value in the graphic display. After driving the
vehicle for up to 20 minutes above 15 mph (24 km/h),
the “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “SERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.

STARTING AND OPERATING 511

For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid, and the EVIC will display aSERVICE TPM
SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.
In addition, the “Tire Pressure Monitoring 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 mph (24 km/h)
in order for the TPMS to receive this information.General Information

•If the gas cap is not tightened properly, the MIL will
come on. Be sure the gas cap is tightened every time
the vehicle is refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a clicking
sound 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 MIL. Resolving
the problem will turn the MIL off.

STARTING AND OPERATING 519

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light” (MIL). It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and drivability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A “gASCAP” message will be
displayed in the odometer. Tighten the gas cap until a
clicking sound is heard. This is an indication that the
570 MAINTAINING YOUR VEHICLE

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Change Oil” or “Oil Change Re-
quired” message is displayed. Severe Operating Condi-
tions can cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last reset. Have your
vehicle serviced as soon as possible, within the next 500
miles (805 km).On Electronic Vehicle Information Center (EVIC)
equipped vehicles, “Oil Change Required” will be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
On Non-EVIC equipped vehicles, “Change Oil” will flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” or under “In-
strument Cluster Description/Odometer/Trip Odom-
eter” in “Understanding Your Instrument Panel” for
further information.
