2018 JEEP GRAND CHEROKEE display

NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
The system will automatically update, the
graphic display of the pressure value(s) will
return to its original color and the Tire Pres-
sure Monitoring Telltale Light will extinguish
once the updated tire pressure(s) have been
received. The vehicle may need to be driven
for up to 10 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 de-
tected. The system fault will also sound a
chime. The instrument cluster display will
display a “SERVICE TPM SYSTEM” message
for a minimum of five seconds. This message
is then followed by a graphic display, with “-
-“ in place of the pressure value(s), indicat-
ing which Tire Pressure Monitoring Sensor(s)
is not being received.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 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 follow-
ing:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
Radio Frequencies as the TPM sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• Lots of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• 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 warninglimit, upon the next ignition switch cycle, the
Tire Pressure Monitoring Telltale Light will
remain on, a chime will sound, and the in-
strument cluster display will still display a
pressure value in the different color graphic
display. After driving the vehicle for up to
10 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 instrument
cluster display will display a “SERVICE TPM
SYSTEM" message for five seconds and then
display dashes (- -) in place of the pressure
value. 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 instrument cluster display 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.
In addition, the Tire Pressure Monitoring Tell-
tale Light will turn off and the graphic in the
instrument cluster display will display a new
SAFETY
98

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 10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this informa-
tion.
TPMS Deactivation — If Equipped
The 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 Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Telltale Light"
will flash on and off for 75 seconds and then
remain on. The instrument cluster will dis-
play the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the
pressure values.Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster 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 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
"TPM Telltale Light" will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYS-
TEM” message and then display pressure
values in place of the dashes. On the next
ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long
as no system fault exists.

and the engine will turn off, however theignition will remain in the ACC mode
(NOT the OFF mode). Never leave a ve-
hicle out of the PARK position, or it could
roll.
4. If the gear selector is in NEUTRAL, and
the vehicle speed is below 5 mph
(8 km/h), pushing the START/STOP but-
ton once will turn the engine off. The
ignition will remain in the ACC mode.
5. If the vehicle speed is above 5 mph
(8 km/h), the ENGINE START/STOP but-
ton must be held for two seconds (or three
short pushes in a row) to turn the engine
off. The ignition will remain in the ACC
mode (NOT the OFF mode) if the engine is
turned off when the transmission is not in
PARK.
NOTE:
The system will automatically time out and
the ignition will cycle to the OFF mode after
30 minutes of inactivity if the ignition is left
in the ACC or RUN (engine not running) mode
and the transmission is in PARK.ENGINE START/STOP Button Functions — With
Driver’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates
similar to an ignition switch. It has three
modes: OFF, ACC, and RUN. To change the

STARTING AND OPERATING
138

To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/START
READY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Instrument Cluster” in “Get-
ting To Know Your Instrument Panel” in
your Owner’s Manual for further informa-
tion.
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and
the brake pedal depressed.
The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. Customer settings will be
maintained upon return to an engine running
condition.
Refer to the “Stop/Start System” in the
“Starting And Operating” section located in
your Owner’s Manual for further information.Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will
check many safety and comfort conditions to
see if they are fulfilled. Detailed information
about the operation of the Stop/Start system
may be viewed in the instrument cluster dis-
play Stop/Start Screen. In the following situ-
ations, the engine will not stop:
• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
• Cabin heating or cooling is in process and
an acceptable cabin temperature has not
been achieved.
• HVAC is set to full defrost mode at a high
blower speed.
• HVAC set to MAX A/C.• Engine has not reached normal operating
temperature.
• The transmission is not in a forward gear.
• Hood is open.
• Vehicle is in 4LO transfer case mode.
• Brake pedal is not pressed with sufficient
pressure.
Other Factors Which Can Inhibit Autostop In-
clude:
• Accelerator pedal input.
• Engine temp too high.
• 5 MPH threshold not achieved from previ-
ous AUTOSTOP.
• Steering angle beyond threshold.
• ACC is on and speed is set.
It may be possible for the vehicle to be driven
several times without the STOP/START sys-
tem going into a STOP/START READY state
under more extreme conditions of the items
listed above.

To Start The Engine While In Autostop
Mode
While in a forward gear, the engine will start
when the brake pedal is released or the
throttle pedal is depressed. The transmission
will automatically re-engage upon engine re-
start.
Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:
• The transmission selector is moved out of
DRIVE.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is
manually adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake
pedal applications).
• STOP/START OFF switch is pushed.
• A STOP/START system error occurs.
• 4WD system is put into 4LO mode.

Instrument Panel” in your Owner’s
Manual for further information.
3. At the next vehicle stop (after turning off
the STOP/START system), the engine will
not be stopped.
4. The STOP/START system will reset itself
back to an ON condition every time the
ignition is turned off and back on.
To Manually Turn On The Stop/Start
System
Push the STOP/START OFF switch (located
on the switch bank). The light on the switch
will turn off.
For complete details on the Stop/Start Sys-
tem refer to the “Stop/Start System” in the

142

display. Refer to “Instrument Cluster Dis-
play“ in “Getting to Know Your Instrument
Panel” for further information.
If the “SERVICE STOP/START SYSTEM”
message appears in the instrument cluster
display, have the system checked by an au-
thorized dealer.
ENGINE BREAK-IN
RECOMMENDATIONS
3.6L & 5.7L Engines
A long break-in period is not required for the
drivetrain (engine, transmission, clutch, and
rear axle) in your new vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. However, wide-open
throttle acceleration in low gear can be det-
rimental and should be avoided.The engine oil, transmission fluid, and axle
lubricant installed at the factory is high-
quality and energy-conserving. Oil, fluid, and
lubricant changes should be consistent with
anticipated climate and conditions under
which vehicle operations will occur. For the
recommended viscosity and quality grades,
refer to “Fluids And Lubricants” in "Techni-
cal Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as an indication of difficulty. Please check
your oil level with the engine oil indicator
often during the break in period. Add oil as
required.
Diesel Engine
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it under
load.
• Do not operate the engine at idle for pro-
longed periods.
• Use the appropriate transmission gear to
prevent engine lugging.
• Observe vehicle oil pressure and tempera-
ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds
when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer tow-
ing or no load operation will extend the time
before the engine is at full efficiency. Re-
duced fuel economy and power may be seen
at this time.
