JEEP CHEROKEE 2018 Owner handbook (in English)

CAUTION!
Damage to the transmission may occur if
the following precautions are not ob-
served:
• Shift into or out of PARK or REVERSEonly after the vehicle has come to a
complete stop.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
The brake pedal must also be pressed to shift
from NEUTRAL into DRIVE or REVERSE
when the vehicle is stopped or moving at low
speeds.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is dis-
played both beside the gear selector and in
the instrument cluster. To select a gear range,
press the lock button on the gear selector and
move the selector rearward or forward. You
must also press the brake pedal to shift thetransmission out of PARK (or NEUTRAL,
when the vehicle is stopped or moving at low
speeds). Select the DRIVE range for normal
driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE
while driving forward), the position indicator
will blink continuously until the selector is
returned to the proper position, or the re-
quested shift can be completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts
on a new vehicle may be somewhat abrupt.
This is a normal condition, and precision
shifts will develop within a few hundred miles
(kilometers).
The nine-speed transmission has been devel-
oped to meet the needs of current and future
FWD/AWD vehicles. Software and calibration
is refined to optimize the customer’s driving
experience and fuel economy. By design,
129

some vehicle and driveline combinations uti-
lize 9th gear only in very specific driving
situations and conditions.
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting be-
tween these gears.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
Electronic Range Select (ERS) shift posi-
tions. Manual downshifts can be made using
the ERS shift control. Moving the gear selec-
tor into the ERS (-/+) position (beside the
DRIVE position) activates ERS mode, dis-
plays the current gear in the instrument clus-
ter, and prevents automatic upshifts beyond
this gear. In ERS mode, toggling the gear
selector forward (-) or rearward (+) will
change the highest available gear.
Refer to “Electronic Range Select (ERS) Op-
eration” in the Owner’s Manual.NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward) it is probably in the
ERS (+/-) position (beside the DRIVE posi-
tion). In ERS mode, the transmission gear
limit (1, 2, 3, etc.) is displayed in the instru-
ment cluster. Move the gear selector to the
right (into the DRIVE [D] position) for access
to PARK, REVERSE, and NEUTRAL.FOUR-WHEEL DRIVE
OPERATION
1-Speed Four-Wheel Drive (4X4) —
If Equipped
This feature provides on-demand four-wheel
drive (4X4). The system is automatic with no
driver inputs or additional driving skills re-
quired. Under normal driving conditions, the
front wheels provide most of the traction. If
the front wheels begin to lose traction, power
is shifted automatically to the rear wheels.
The greater the front wheel traction loss, the
greater the power transfer to the rear wheels.
Gear Selector
STARTING AND OPERATING
130

Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
pre-emptive effort to improve vehicle launch
and performance characteristics.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the
power transfer unit.
2-Speed Four-Wheel Drive (4x4) —
If Equipped
The Four-Wheel Drive is fully automatic in the
normal driving mode. The Selec-Terrain but-
tons provide three selectable mode positions:
• 4WD LOW
• REAR LOCK (If Equipped)
• NEUTRAL
1-Speed 4X4 Switch
2-Speed 4x4 Switch
2-Speed 4x4 Switch (with Rear Lock)
131

When additional traction is required, the
4WD LOW range position can be used to
provide an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces
only. Driving in 4WD LOW on dry, hard-
surfaced roads may cause increased tire wear
and damage to driveline components.
When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the normal driving mode at a
given road speed. Take care not to overspeed
the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference
will adversely affect shifting and cause dam-
age to the driveline components.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
NEUTRAL
This range disengages the driveline from the
powertrain.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and
remain on solid when the shift is complete.
STARTING AND OPERATING
132

NOTE:
If shift conditions/interlocks are not met, a
message will flash from the instrument clus-
ter display with instructions on how to com-
plete the requested shift. Refer to “Instru-
ment Cluster Display” in “Getting To know
Your Instrument Panel” for further informa-
tion.
Shifting Out Of 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will flash and go out when
the shift is complete.
NOTE:
• If shift conditions/interlocks are not met, amessage will flash from the instrument
cluster display with instructions on how to
complete the requested shift. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
•
Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped; however,
difficulty may occur due to the mating clutch
teeth not being properly aligned. Several at-
tempts may be required for clutch teeth align-
ment and shift completion to occur. The pre-
ferred method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is moving
faster than 3 mph (5 km/h), the 4WD system
will not allow the shift.
NEUTRAL Shift Procedure
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
1. Bring the vehicle to a complete stop on level ground and shift the automatic
transmission to PARK.
2. Turn the engine OFF.
3. Turn the ignition to the ON/RUN mode, but do not start the engine.
4. Press and hold the brake pedal.
Selec-Terrain Switch
133

5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object,push and hold the recessed power transfer
unit NEUTRAL (N) button (located by the
selector switch) for four seconds. The
light behind the NEUTRAL (N) symbol
will blink, indicating shift in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is
complete. 7. After the shift is completed and the NEU-
TRAL (N) light stays on, release the NEU-
TRAL (N) button.
8. Start the engine.
9. Release the parking brake.
10. Shift the transmission into REVERSE.
11. Release the brake pedal (and clutch pedal on manual transmissions) for five
seconds and ensure that there is no
vehicle movement.
12. Shift the transmission to NEUTRAL.
13. Apply the parking brake.
14. Shift the automatic transmission into PARK, or place manual transmission in
gear (NOT in Neutral). Turn the engine
OFF, and remove the key fob.
Repeat steps 1-7 to shift out of NEUTRAL.Rear Electronic Locker (E-Locker) System
— If Equipped
The Rear E-Locker System features a me-
chanical locking rear differential to provide
better traction in the 4WD LOW position. The
“REAR LOCK” button is on the Selec-Terrain
Knob.
Activating The Rear E-Locker
To activate the Rear E-Locker System, the
following conditions must be met:
1. The 4WD system must be in 4WD LOW.
2. The ignition in the ON mode and the engine running.
3. Vehicle speed must be below 15 MPH (24 km/h).
4. To engage Rear E-Locker, push the REAR LOCK button once.
Deactivating The Rear E-Locker System
To deactivate the Rear E-Locker System, the
following conditions must be met:
1. Rear E-Locker must be engaged, and the REAR LOCK indicator light on.
Neutral Switch
STARTING AND OPERATING
134

2. The ignition in the ON mode and theengine running.
3. To disengage Rear E-Locker, push the REAR LOCK button once.
NOTE:
• It may also be necessary to drive slowly steering back and forth to complete en-
gagement and disengagement of the
E-Locker.
• When engaging Rear E-Locker, the indica- tor lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain on.
• When disengaging Rear E-Locker, the indi- cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.
• Shifting into or out of Rear E-Locker is possible with the vehicle completely
stopped; however, difficulty may occur due
to the mating clutch teeth not being prop-
erly aligned. Several attempts may be re-
quired for clutch teeth alignment and shift
completion to occur. The preferred method is for the vehicle to be rolling, below
15 MPH (24 km/h), while including right
and left steering maneuvers to allow for the
clutch teeth to align.
• The Rear E-Locker System must be disen- gaged prior to taking the vehicle out of 4WD
LOW range. If 4WD LOW shift conditions/
interlocks are not met, a message will flash
from the instrument cluster display with
instructions on how to complete the re-
quested shift.
SELEC-TERRAIN
Description
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Rotate the Selec-Terrain knob to select the
desired mode. Selec-Terrain offers the following modes:
•
Auto — Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering
feel to provide improved handling and ac-
celeration over two-wheel drive vehicles.
• Snow — Tuning set for additional stability
in inclement weather. Use on and off road
on loose traction surfaces such as snow.
When in SNOW mode (depending on cer-
Selec-Terrain Switch
135

tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
• Sport — This mode alters the transmis-
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD LOW
is selected.
• Sand/Mud — Off-road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less
forgiving surfaces. The electronic brake
controls are set to limit traction control
management of throttle and wheel spin.
• Rock — Off-road calibration only available
in 4WD LOW range. Traction based tuning
with improved steer-ability for use on high
traction off-road surfaces. Use for low
speed obstacles such as large rocks, deep
ruts, etc. NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control for steep downhill control.
See “Electronic Brake Control System” in
“Safety” for further information.
STOP/START SYSTEM —
IF EQUIPPED
The Stop/Start function was developed to
reduce fuel consumption. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Releasing the brake pedal or pressing the
accelerator pedal will automatically restart
the engine.
This vehicle has been upgraded with a Heavy
Duty Battery, Starter, as well as other engine
parts, to handle the Additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. 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 “Au-
tostop” 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 “Warning Lights And Mes-
sages” in “Getting To Know Your Instru-
ment Panel” in your Owner’s Manual.
• The vehicle must be completely stopped.
• The gear selector 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.
STARTING AND OPERATING
136

Refer to the “Stop/Start System” in the
“Starting And Operating” in your Owner’s
Manual.
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 andan 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 or reverse gear.
• Hood is open.
• Vehicle is in 4LO transfer case mode (if equipped with 4WD).
• Brake pedal is not pressed with sufficient pressure with vehicle in DRIVE position.
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 gear selector is moved out of DRIVE except in the PARK position.
• 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 (if equipped with 4WD).
137

Conditions That Force An Application Of The
Electric Park Brake While In Autostop Mode:
• The driver’s door is open and brake pedalreleased.
• The driver’s door is open and the driver’s 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.

in “Getting To Know Your Instrument
Panel” in your Owner’s Manual.
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 the ON mode every time the igni-
tion 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.
