2018 JEEP CHEROKEE automatic transmission

Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. It will remain
in STOP/START NOT READY until you drive
forward with a vehicle speed greater than
4 mph (7 km/h). At that time, the system will
go into STOP/START READY and if all other
conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop”
mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/STARTREADY 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 Display”
in “Getting To Know Your Instrument
Panel” in your Owner’s information for fur-
ther details.
• The vehicle must be completely stopped.
• The gear selector must be in DRIVE and the brake pedal depressed (automatic trans-
mission) or the gear selector must be in
NEUTRAL and the clutch pedal must be
fully released (manual transmission). 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. While in Autostop, the Cli-
mate Controls system may automatically ad-
just airflow to maintain cabin comfort. Cus-
tomer settings will be maintained upon return
to an engine running condition.
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
Stop/Start Screen. In the following situations
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.
• 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.
• Engine has not reached normal operating temperature.
• Battery charge is low.
• The transmission is not in DRIVE (auto- matic transmission) or NEUTRAL (manual
transmission).
• Hood is open.
• Vehicle is in 4LO transfer case mode.
• Exhaust system regeneration in process.
Other Factors Which Can Inhibit Autostop In-
clude:
• Fuel level.
• Accelerator pedal input (automatic trans- mission only).
• Engine temperature too high.
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
Automatic Transmission:
While in DRIVE, the engine will start when
the brake pedal is released or the throttle
pedal is depressed. The transmission will
automatically re-engage upon engine restart.
During this transition, the brakes will hold
the vehicle to avoid undesired vehicle move-
ment.
Manual Transmission:
When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/
START SYSTEM NOT READY mode until the
vehicle speed is greater than 4 mph (7 km/h).
Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:
• The transmission gear selector is movedfrom DRIVE to REVERSE or NEUTRAL.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode. • Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake
pedal applications).
• STOP/START OFF switch is pushed.
• 4WD system is put into 4LO mode.
• The emissions system requires it.
• A STOP/START system error occurs.
• HVAC system temperature or fan speed is manually adjusted.
Conditions That Force An Application Of The
Electric Park Brake While In Autostop Mode:
• The driver door is open and brake pedal released.
• The driver door is open and the driver seat belt is unbuckled.
• The engine hood has been opened.
• A STOP/START system error occurs.
If the Electric Park Brake is applied with the
engine off, the engine may require a manual
restart and the electric park brake may re-
quire a manual release (depress brake pedal
and push Electric Park Brake switch). Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” in your Own-
er’s Manual for further information.
To Manually Turn Off The Stop/Start
System
1. Push the STOP/START Off switch (located
on the switch bank). The light on the
switch will illuminate.
2. The “STOP/START OFF” message will ap- pear in the instrument cluster display.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel”
in your Owner’s manual for further
information.

WARNING!
• Never add fuel when the engine is run-ning. This is in violation of most coun-
tries regulations and may cause the
“Malfunction Indicator Light” to turn
on.
• A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always
place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissioncontrol system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.
• A poorly fitting fuel filler cap may cause
the MIL to turn on.
CAUTION!
• To avoid fuel spillage and overfilling, donot “top off” the fuel tank after filling.
• If fuel is spilled on surface on the paint,
clear it immediately to avoid damage the
paint.

WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Preparations For Jacking
1. Park the vehicle on a firm level surface asfar from the edge of the roadway as pos-
sible. Avoid icy or slippery areas.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.
4. Place the gear selector into PARK (auto- matic transmission) or REVERSE (manual
transmission). 5. Turn the ignition off to the LOCK position.
6. Chock both the front and rear of the wheel
diagonally opposite of the jacking posi-
tion. For example, if changing the right
front tire, chock the left rear wheel.
NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
Jacking Instructions
WARNING!
Carefully follow these tire changing warn-
ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface as far from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Chock the wheel diagonally opposite the
wheel to be raised.
• Apply the parking brake firmly and set
an automatic transmission in PARK; a
manual transmission in REVERSE.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when
it is on a jack.
• Do not get under the vehicle when it is
on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.

GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily move the gear selector:
1. Turn the engine OFF.
2. Apply the parking brake.
3. Using a screwdriver or similar tool, care-fully separate the shifter bezel and boot
assembly from the center console, and
raise it up to access the gear selector
mechanism.
4. Press and maintain firm pressure on the brake pedal.
5. Insert a small screwdriver or similar tool down into the gear selector override ac-
cess hole (at the left front corner of the
gear selector assembly), and push and
hold the override release lever down.
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left
to clear the area around the front wheels. For
vehicles with automatic transmission, push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or
SECOND GEAR and REVERSE (with manual
transmission), while gently pressing the ac-
celerator.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND GEAR and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
• You must ensure that the Auto Park Brakefeature is disabled before towing this ve-
hicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the cus-
tomer programmable features in the
Uconnect Settings.
• Vehicles with a discharged battery or total electrical failure when the electric park
brake (EPB) is engaged, will need a wheel
dolly or jack to raise the rear wheels off the
ground when moving the vehicle onto a
flatbed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
Note that the Safehold feature will engage
the Electric Park Brake whenever the driver's
door is opened (if the battery is connected,
ignition is ON, transmission is not in PARK,
and brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and then
releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission out of PARK so that the vehicle can
be moved.
CAUTION!
• Do not use sling-type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
CAUTION!
suspension components. Damage to
your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Front-Wheel Drive (FWD) Models — With
Key Fob
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.
