instrument cluster JEEP GRAND CHEROKEE 2021 Owner handbook (in English)

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 information.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (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 TPMS Warning 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
TPMS Warning 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.
OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air
Bags
• Supplemental Active Head Restraints
• Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
Important Safety Precautions
Please pay close attention to the information
in this section. It tells you how to use your
restraint system properly, to keep you and
your passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
air bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of
a vehicle with a rear seat.
107

3. The system takes over and attempts to
start the vehicle. If the vehicle fails to
start, the starter will disengage automati-
cally after 10 seconds.
4. If you wish to stop the cranking of the
engine prior to the engine starting, push
the button again.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
To Turn Off The Engine Using ENGINE START/
STOP Button
1. Place the gear selector in PARK, then
push and release the ENGINE START/
STOP button.
2. The ignition will return to the OFF mode.
3. If the gear selector is not in PARK (with
vehicle stopped) and the ENGINE START/
STOP button is pushed once, the trans-
mission will automatically select PARK
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
ignition modes without starting the vehicle
and use the accessories, follow these steps:
1. Starting with the ignition in the OFF
mode,
2. Push the ENGINE START/STOP button
once to place the ignition to the ACC

ment cluster. For further information, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel”.
AutoPark
AutoPark is a supplemental feature to assist
in placing the vehicle in PARK should the
situations on the following pages occur. It is a
back up system and should not be relied upon
as the primary method by which the driver
shifts the vehicle into PARK.
The conditions under which AutoPark will
engage are outlined on the following pages.
WARNING!
• Driver inattention could lead to failure to
place the vehicle in PARK. ALWAYS DO
A VISUAL CHECK that your vehicle is in

after every normal customer en-
gine start. At that time, the sys-
tem will go into STOP/START
READY and if all other conditions are met,
can go into a STOP/START AUTOSTOP AC-
TIVE “Autostop” mode.
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 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 (8 km/h) threshold not achieved
from previous 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).

System Malfunction
If there is a malfunction in the STOP/START
system, the system will not shut down the
engine. A “SERVICE STOP/START SYSTEM”
message will appear in the instrument cluster
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.
STOP/START Off Switch

mode. An onboard frequency generator cre-
ates counteracting sound waves through the
audio system to help keep the vehicle quiet.
Eight–Speed Automatic Transmission
Your vehicle is equipped with a fuel efficient
8 speed transmission. The gear selector is
located in the center console.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE and
MANUAL or SPORT (AutoStick) shift posi-tions. Manual shifts can be made using the
AutoStick shift control. Toggling the gear se-
lector forward (-) or rearward (+) while in the
MANUAL or SPORT (AutoStick) position (be-
side the DRIVE position), or tapping the shift
paddles (+/-), will manually select the trans-
mission gear, and will display the current gear
in the instrument cluster. Refer to
"AutoStick" in this section for further infor-
mation.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE
position). In AutoStick mode, the transmis-
sion gear (1, 2, 3, etc.) is displayed in the
instrument cluster. Move the gear selector to
the right (into the DRIVE [D] position) for
access to PARK, REVERSE, and NEUTRAL.
AutoStick
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving
you more control of the vehicle. AutoStick
allows you to maximize engine braking, elimi-
nate undesirable upshifts and downshifts,and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip-
pery conditions, mountain driving, trailer
towing, and many other situations.
Operation
To activate AutoStick mode, move the gear
selector into the MANUAL (M) or SPORT (S)
position (beside the DRIVE position), or tap
one of the shift paddles on the steering
wheel. Tapping the (-) shift paddle to enter
AutoStick mode will downshift the transmis-
sion to the next lower gear, while tapping (+)
to enter AutoStick mode will retain the cur-
rent gear. The current transmission gear will
be displayed in the instrument cluster. In
AutoStick mode, you can use the gear selec-
tor (in the MANUAL or SPORT position), orTransmission Gear Selector
Shift Paddles
157

the shift paddles, to manually shift the trans-
mission. Tapping the gear selector forward (-)
while in the MANUAL (M) or SPORT (S)
position, or tapping the (-) shift paddle, will
downshift the transmission to the next lower
gear. Tapping the selector rearward (+) (or
tapping the (+) shift paddle) will command
an upshift.
NOTE:
The shift paddles may be disabled (or re-
enabled, as desired) using the Uconnect Per-
sonal Settings or, in SRT models, using Drive
Modes.
In AutoStick mode, the transmission will
shift up or down when (+/-) is manually se-
lected by the driver (using the gear selector,
or the shift paddles), unless an engine lug-
ging or overspeed condition would result. It
will remain in the selected gear until another
upshift or downshift is chosen, except as
described below.
• The transmission will automatically down-
shift as the vehicle slows (to prevent engine
lugging) and will display the current gear.• The transmission will automatically down-
shift to first gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle
is accelerated.
• You can start out, from a stop, in first or
second gear (or third gear, in 4LO range,
Snow mode, or Sand mode). Tapping (+) (at
a stop) will allow starting in second gear.
Starting out in second or third gear can be
helpful in snowy or icy conditions.
• If a requested downshift would cause the
engine to over-speed, that shift will not
occur.
• The system will ignore attempts to upshift
at too low of a vehicle speed.
• Holding the (-) paddle depressed, or hold-
ing the gear selector in the (-) position, will
downshift the transmission to the lowest
gear possible at the current speed.
• Transmission shifting will be more notice-
able when AutoStick is enabled.
• The system may revert to automatic shift
mode if a fault or overheat condition is
detected.NOTE:
When Selec-Speed or Hill Descent Control is
enabled, AutoStick is not active.
To disengage AutoStick, return the gear se-
lector to the DRIVE position, or press and
hold the (+) shift paddle (if the gear selector
is already in DRIVE) until "D" is once again
indicated in the instrument cluster. You can
shift in or out of AutoStick at any time with-
out taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.STARTING AND OPERATING
