2018 JEEP GRAND CHEROKEE Owner handbook (in English)

•Mud– Off road calibration for use on low
traction surfaces such as mud. Driveline is
maximized for traction. Some binding may
be felt on less forgiving surfaces. The elec-
tronic brake controls are set to limit traction
control management of throttle and wheel
spin. If equipped with air suspension, the
level will change to Off Road 1.
•Rock– Off road calibration only available in
4WD Low range. The vehicle is raised (if
equipped with Air Suspension) for im-
proved ground clearance. 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. If equipped with air suspen-
sion, the vehicle level will change to Off-
Road 2. If the Selec-Terrain switch is in
ROCK mode, and the transfer case is
switched from 4WD Low to 4WD High, the
Selec-Terrain system will return to AUTO.
NOTE:
Activate the Hill Descent Control or Selec
Speed Control for steep downhill control. See
“Electronic Brake Control System” in this
section for further information.Instrument Cluster Display Messages
When the appropriate conditions exist, a
message will appear in the instrument clus-
ter. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
SELEC-TRACK — IF
EQUIPPED (SRT)
Description
Selec-Track combines the capabilities of the
vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Rotate the Selec-Track knob to select the
desired mode.Refer to “SRT Drive Modes” in the “Multime-
dia” section in your Owner’s Manual for fur-
ther information.

•Track– Track road calibration for use on
high traction surfaces. Driveline is maxi-
mized for traction. Some binding may be
felt on less forgiving surfaces. This feature
will reset to AUTO on an ignition cycle.
•To w– Use this mode for towing and hauling
heavy loads. Vehicle suspension will go to
sport mode. Trailer sway control is enabled
in the ESC system. This feature will reset to
AUTO upon an ignition cycle.
Custom
This mode allows the driver to create a cus-
tom vehicle configuration that is saved for
quick selection of favorite settings. The sys-
tem will return to AUTO mode when the
ignition switch is cycled from RUN to OFF to
RUN, if this mode is selected. While in Cus-
tom Mode the Stability, Transmission, Steer-
ing, Suspension, all-wheel drive set up, and
Paddle shifter settings may be configured
through the custom mode set-up.
NOTE:
Refer to “SRT Drive Modes” in the “Multime-
dia” section in your Owner’s Manual for fur-
ther information.
Active Damping System
This vehicle is equipped with an electronic
controlled damping system. This system re-
duces body roll and pitch in many driving
situations including cornering, acceleration
and braking. There are 3 modes:
•Street Mode(Available in terrain positions
AUTO, SNOW and CUSTOM.) — Used dur-
ing highway speeds where a touring sus-
pension feel is desired.
•Sport Mode(Available in terrain positions
AUTO, SPORT, CUSTOM and TOW.) — Pro-
vides a firm suspension for better handling.
•Track Mode(Available in terrain positions
AUTO, TRACK and CUSTOM.) — Provides
a full firm suspension for an aggressive
track experience.
Refer to “SRT Drive Modes” in the “Multime-
dia” section in your Owner’s Manual for fur-
ther information.
Launch Control— If Equipped
This vehicle is equipped with a Launch Con-
trol system that is designed to allow the driver
to achieve maximum vehicle acceleration in astraight line. Launch Control is a form of
traction control that manages tire slip while
launching the vehicle. This feature is in-
tended for use during race events on a closed
course where consistent quarter mile and
zero to sixty times are desired. The system is
not intended to compensate for lack of driver
experience or familiarity with the race track.
Use of this feature in low traction (cold, wet,
gravel, etc.) conditions may results in excess
wheel slip outside this systems control result-
ing in an aborted launch.
Preconditions:
• Launch Control should not be used on pub-
lic roads. Always check track conditions
and the surrounding area.
• Launch Control is not available within the
first 500 miles (805 km) of engine break-
in.
• Launch Control should only be used when
the engine and transmission are at operat-
ing temperature.
• Launch Control is intended to be used on
dry, paved road surfaces only.

CAUTION!
Use on slippery or loose surfaces may
cause damage to vehicle components and
is not recommended.
Launch Control is only available when the
following procedure is followed:
NOTE:
Pushing the SRT button on the Select-Track
switch or pressing the “Apps” button on the
touchscreen are the two options to access
launch control features. Please refer to “SRT
Drive Modes” in “Multimedia” in your Own-
er’s Manual for further information.
1. Press the “Race Options” button on the
touchscreen or push the LAUNCH button
on the Select-Track switch.
2. Press the “Launch RPM Set-Up” button
on the touchscreen. This screen will allow

• Apply brake pressure.
• While holding the brake, rapidly apply
and hold the accelerator pedal to wide
open throttle. The engine speed will
hold at the RPM that was set in the
“Launch RPM Set-up” screen.
NOTE:
Messages will appear in the instrument
cluster display to inform the driver if one
or more of the above conditions have not
been met.
4. When the above conditions have been
met, the instrument cluster display will
read “Release Brake”.
5. Keep the vehicle pointed straight.Launch control will be active until the vehicle
reaches 62 mph (100 km/h), at which point
the Electronic Stability Control (ESC) system
will return to its current ESC mode.
Launch control will abort before launch
completion, display “Launch Aborted” in the
cluster under any the following conditions:
• The accelerator pedal is released during
launch.
• The ESC system detects that the vehicle is
no longer moving in a straight line.
• The “ESC OFF” button is pressed to change
the system to another mode.

Guidelines For Track Use
NOTE:
Because of the extreme conditions encoun-
tered during track use, any damage or wear
associated with track use may not be covered
by warranty.
• If your SRT vehicle is equipped with Drive
Modes they will alter the vehicle’s perfor-
mance in various driving situations. It is
recommended that your vehicle operates in
SPORT or TRACK modes during the track
event.
• Prior to each track event/day, verify all
fluids are at the correct levels. Refer to
“Fluid Capacities” in “Technical Specifica-
tions” for further information.
• Prior to each track event, verify the front
and rear brake pads have more than ½ pad
thickness remaining. If the brake pads re-
quire changing, please burnish prior to
track outing at full pace.
NOTE:
Use of DOT 4 brake fluid is suggested for
extended track usage due to increased ther-
mal capacity.• At the conclusion of each track event, it is
recommended that a brake bleed proce-
dure is performed to maintain the pedal
feel and stopping capability of your Brembo
High Performance brake system.
• It is recommended that each track outing
should end with a minimum of one cool
down lap using minimal braking.
• If equipped with a removable lower front
fascia grille, it is recommended to remove it
for track use during warm/hot weather to
improve cooling airflow to critical pow-
ertrain and cooling system components.
• All SRT vehicles are track tested for
24 hours of endurance, however, it is rec-
ommended that suspension system, brake
system, prop shaft, and ½ shaft boots
should be checked for wear or damage after
every track event.
• Track usage results in increased operating
temperatures of the engine, transmission,
driveline and brake system. This may affect
noise vibrations and harshness (NVH)
countermeasures designed into your ve-
hicle. New components may need to be
installed to return the system to the original
NVH performance.• Tire pressure:
– 40 psi (276 kpa) hot, recommend
32 psi (221 kpa) front, 30 psi
(207 kpa) rear cold
NOTE:
It is recommended that you target 40 psi
(276 kpa) Hot Tire Pressure at the conclusion
of each track session. Starting at 32 psi
(221 kpa) Front & 30 psi (207 kpa) Rear
Cold and adjusting based on ambient & track
conditions is recommended. Tire pressure
can be monitored via the instrument cluster
display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use,
the brake pads and rotors must have a ther-
mal burnish for factory installed components
or when new brake friction components are
installed:
1. Use one track session to burnish brakes
by driving at 75% speed. Brake at ap-
proximately 0.60-0.80g maximum with-
out ABS intervention.
STARTING AND OPERATING
162

2. Lap the track in this manner until you
start smelling the brakes. Continue for
another ½ lap at speed, then do a two lap
cool down with minimal brake applies.
Make sure the brakes are not smoking. If
they are, do another cool down lap.
3. Do not continue for more than one full
burnishing lap after you start smelling the
brakes. Do not get them smoking heavily.
This will get them too hot and affect their
life negatively in future track use.
4. Allow vehicle to sit and cool in the pad-
dock for at least 30 min. If an infrared
thermal gun is available, allow rotors to
cool to 200°F (93.3°C) before going back
out.
5. There should be a thin, ash layer when
inspecting the pads installed in the cali-
per. Having the ash layer go more than
half the thickness of the pad material
indicates too aggressive of a burnish.
6. Sometimes, a second burnish session is
required. If the pads start smelling in the
next track session, reduce speed and
braking decel to burnish targets and fol-
low step 2-4.7. New pads installed on old rotors still need
to be burnished. New rotors installed with
old pads should be burnished at the track
or street driven for 300 city miles to
develop an adequate lining transfer layer
on the rotor surface prior to track use.
8. Rotors that pulsate during track use
should be replaced. Resurfacing of the
rotors is not recommended, as it removes
mass from the rotor, reducing its thermal
capacity. Resurfacing also thins the rotor
cheek, making it less robust and increas-
ing the likelihood of pulsation in further
track use.
SPEED CONTROL
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
25 mph (40 km/h).
The Speed Control buttons are located on the
right side of the steering wheel.
Speed Control Switches
1 — Push CANC/Cancel
2 — Push SET (+)/Accel
3 — Push RES/Resume
4 — Push On/Off
5 — Push SET (-)/Decel

NOTE:
In order to ensure proper operation, the
Speed Control System has been designed to
shut down if multiple Speed Control func-
tions are operated at the same time. If this
occurs, the Speed Control System can be
reactivated by pushing the Speed Control
on/off button and resetting the desired ve-
hicle set speed.
Activation
Push the on/off button to activate the speed
control. CRUISE CONTROL READY will ap-
pear on the instrument cluster display to

Leaving the Speed Control system on when
not in use is dangerous. You could acci-
dentally set the system or cause it to go
faster than you want. You could lose con-
trol and have an accident. Always leave the
system off when you are not using it.
Setting A Desired Speed
Turn the Speed Control on. When the vehicle
has reached the desired speed, push the SET
(+) or SET (-) button and release. Release the
accelerator and the vehicle will operate at the
selected speed. Once a speed has been set a
message CRUISE CONTROL SET TO MPH
(km/h) will appear indicating what speed was
set. A cruise indicator lamp, along with set
speed will also appear and stay on in the
instrument cluster display when the speed is
set.
Varying The Speed
Once the Speed Control has been activated,
the speed can be increased or decreased.
To Increase Speed
When the Speed Control is set, you can in-
crease speed by pushing the SET(+)button.
The driver's preferred units can be selected
through the instrument panel settings if
equipped. Refer to “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
more information. The speed increment
shown is dependant on the chosen speed unit
of U.S. (mph) or Metric (km/h):

Resume Speed
To resume a previously set speed, push the
RES button and release. Resume can be used
at any speed above 20 mph (32 km/h).
Accelerating For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Deactivation
A soft tap on the brake pedal, pushing the
CANC button, or normal brake pressure while
slowing the vehicle will deactivate the Speed
Control without erasing the set speed from
memory.
Pushing the on/off button or turning the igni-
tion switch OFF erases the set speed from
memory.
ADAPTIVE CRUISE
CONTROL (ACC)
If your vehicle is equipped with Adaptive
Cruise Control, the controls operate exactly
the same as the speed control with only a
couple of differences. With this option you
can set a specified distance you would like to
maintain between you and the vehicle in front
of you.
165

If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceleration
automatically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
Activation
Push and release the Adaptive Cruise Control
(ACC) on/off button.
“ACC READY” will appear in the instrument
cluster display to indicate the ACC is on.
Setting A Desired Speed
When the vehicle reaches the speed desired,
push the SET(+)button or the SET(-)button
and release. The instrument cluster display
will show the set speed.
If the system is set when the vehicle speed is
below 19 mph (30 km/h), the set speed shall
be defaulted to 19 mph (30 km/h). If the
system is set when the vehicle speed is above
19 mph (30 km/h), the set speed shall be the
current speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary
vehicle in front of your vehicle in close prox-
imity.Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this oc-
curs:
• The message “DRIVER OVERRIDE” will
appear in the instrument cluster display.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be de-
termined by the position of the accelerator
pedal.
Varying The Speed
Once the ACC has been activated, the speed
can be increased or decreased.
NOTE:
• When you override and push the SET(+)
button or SET(-)buttons, the new set
speed will be the current speed of the
vehicle.
• When you use the SET(-)button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.Adaptive Cruise Switches
