2013 JEEP GRAND CHEROKEE evic system

The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds, and remain on
solid when a system fault is detected. In addi-
tion, a “SERVICE TPM SYSTEM” message
may be displayed for approximately 5 seconds
when a system fault is detected, and a chime
will sound. If the ignition switch is cycled, this
sequence will repeat, providing the system fault
still exists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no
longer exists. 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 Fre-
quencies 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.NOTE:There is no 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, a
chime will sound, a “LOW TIRE PRESSURE”
message will be displayed in the instrument
cluster for a minimum of five seconds, an
Inflate to XXX
message will be displayed and
the Tire Pressure Monitoring Telltale Light will
turn ON. 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, a “SERVICE TPM SYSTEM”
message will be displayed for a minimum of
five seconds. For each subsequent ignition
switch cycle, a chime will sound, a “SERVICE
TPM SYSTEM” message will be displayed for
a minimum of five seconds, and the Tire Pres-
sure Monitoring Telltale Light will flash on and
off for 75 seconds and then remain on solid. 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 automati-
cally and the Tire Pressure Monitoring 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. 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.
Premium System – If EquippedThe Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure 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 regu-
larly check the tire pressure in all of your
tires and to maintain the proper pressure.
269

The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
•
Various Tire Pressure Monitoring System Mes-
sages, which display in the Electronic Vehicle
Information Center (EVIC), and a graphic dis-
playing tire pressures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, and an audible chime will be
activated, when one or more of the four
active road tire pressures are low. In addition, the
EVIC will display a “LOW TIRE PRESSURE”
message for a minimum of five seconds, an
"Inflate to XXX" message and a graphic display of
the pressure value(s) with the low tire(s) “flash- ing.” Refer to “Electronic Vehicle Information Cen-
ter (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
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 displayed inthe
"Inflate to XXX" message. The system will
automatically update, the graphic display of the
pressure value(s) will stop “flashing,” and the
Tire Pressure Monitoring Telltale Light will extin-
guish 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 mes-
sage is then followed by a graphic display, with
“- -“ in place of the pressure value(s), indicating
which Tire Pressure Monitoring Sensor(s) is not
being received.
NOTE:
Your system can be set to display pressure
units in PSI or kPa.
270

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 Pres-
sure Monitoring Telltale Light will no longer
flash, the"SERVICE TPM SYSTEM" message
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 Fre-
quencies 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 sec-
onds when a system fault is detected possibly
related to an incorrect sensor location fault. In
this case, the "SERVICE TPM SYSTEM" mes-
sage 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 the "SER-
VICE TPM SYSTEM" message exists.
NOTE:
There is no 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 and an
Inflate to
XXX kPa message will be displayed. 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 five seconds
and then display dashes (- -) in place of the
pressure value. For each subsequent igni-
tion 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 a
SERVICE TPM SYSTEM message for 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.
271

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.
TPMS DeactivationThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 24 km/h (15 mph). The TPMS
will chime, the"TPM Telltale Light" will flash on
and off for 75 seconds and then remain on and the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYS-
TEM” message and then display dashes (--) in
place of the pressure values. Beginning with the
next ignition switch cycle, the TPMS will no
longer chime or display the “SERVICE TPM
SYSTEM” message in the EVIC but dashes (--)
will remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 24 km/h
(15 mph). The TPMS will chime, the
"TPM
Telltale Light" will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message. The
EVIC will also display pressure values in place
of the dashes. On the next ignition switch cycle
the "SERVICE TPM SYSTEM" message will no
longer be displayed as long as no system fault
exists.

TRAILER TOWING
In this section you will find safety tips and infor-
mation on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible. To maintain warranty coverage, follow the require-
ments and recommendations in this manual con-
cerning vehicles used for trailer towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be
limited so that you do not exceed the GVWR.
Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting and Operating” for further
information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its
"loaded and ready for operation "
condition. The recommended way to measure
GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer
must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination.
NOTE:
The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include an adaptive
drive strategy to avoid frequent shifting when
towing. However, if frequent shifting does occur
while in DRIVE, select TOW mode, or use the
AutoStick® shift control to select a lower gear.
NOTE:
Using TOW mode or selecting a lower gear
while operating the vehicle under heavy load-
ing conditions, will improve performance and
extend transmission life by reducing exces-
sive shifting and heat buildup. This action will
also provide better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then change
the transmission fluid and filter(s) as specified for
"police, taxi, fleet, or frequent trailer towing. Refer
to the “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experi-
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
• Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

7. Using the point of a ballpoint pen or similar
object, press and hold the recessed transfer
case NEUTRAL (N) button (located by the se-
lector switch) for four seconds. The light behind
the N symbol will blink, indicating shift in prog-
ress. The light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is complete. A
"FOUR WHEEL DRIVE SYSTEM IN NEU-
TRAL"message will display on the EVIC (Elec-
tronic Vehicle Information Center). Refer to
"Electronic Vehicle Information Center (EVIC)"
in "Understanding Your Instrument Panel "for
further information. 8. After the shift is completed and the NEU-
TRAL (N) light stays on, release the NEUTRAL
(N) button.
9. Start the engine.
10. Shift the transmission into REVERSE.
11. Release the brake pedal for five seconds
and ensure that there is no vehicle movement.
12. Turn the engine OFF, then turn the ignition
switch back to the ON/RUN position without
starting the engine.
13. Firmly apply the parking brake.
14. Shift the transmission into PARK.
CAUTION!
Damage to the transmission may occur if the
transmission is shifted into PARK with the
transfer case in NEUTRAL (N) and the en-
gine running. With the transfer case in NEU-
TRAL (N) ensure that the engine is OFF
before shifting the transmission into PARK.15. Attach the vehicle to the tow vehicle using a
suitable tow bar.
16. Release the parking brake.
17. Disconnect the negative battery cable, and
secure it away from the negative battery post.
NOTE:
•
Steps 1 through 6 are requirements that
must be met before pressing the NEU-
TRAL (N) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
before pressing the NEUTRAL (N) button
or are no longer met during the shift, then
the NEUTRAL (N) indicator light will flash
continuously until all requirements are
met or until the NEUTRAL (N) button is
released.

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 emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light (MIL).” It will also store diagnos-
tic codes and other information to assist your
service technician in making repairs. Although
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 con-
trol system. It could also affect fuel economy
and drivability. The vehicle must be serviced
before any emissions tests can be per-
formed.
•If the MIL is flashing, while the engine is
running, severe catalytic converter dam-
age and power loss will soon occur. Imme-
diate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system de-
termines that the fuel filler cap is
loose, improperly installed, or dam-
aged, a loose gascap indicator will
display in the EVIC telltale display
area. Refer to “Electronic Vehicle
Information Center (EVIC) in “Understanding
Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and press the SELECT button to turn off the message. If the
problem continues, the message will appear the
next time the vehicle is started.
A loose, improperly installed, or damaged fuel
filler cap may also turn on the Malfunction
Indicator Light (MIL).
REPLACEMENT PARTS
Use of genuine MOPAR® parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR® parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
MAINTENANCE PROCEDURES
The pages that follow contain the
required
maintenance services determined by the engi-
neers who designed your vehicle.
Besides those maintenance items specified in
the fixed maintenance schedule, there are other
components which may require servicing or
replacement in the future.
