2020 JEEP GRAND CHEROKEE Owner handbook (in English)

Automatic height changes will occur based
on vehicle speed and the current vehicle
height. The indicator lamps and instrument
cluster display messages will operate the
same for automatic changes and user re-
quested changes.
• Off-Road 2 (OR2) – Indicator lamps 4, 5,
and 6 will be illuminated when the vehicle
is in OR2.
• Off-Road 1 (OR1) – Indicator lamps 4 and
5 will be illuminated when the vehicle is in
OR1.
• Normal Ride Height (NRH) – Indicator
lamp 4 will be illuminated when the vehicle
is in this position.
• Entry/Exit Mode – Indicator lamp 3 will be
illuminated when the vehicle is in Entry/
Exit Mode. If Entry/Exit Mode is requested
while vehicle speed is between 15 mph
(24 km/h) and 25 mph (40 km/h), indicator
lamp 4 will remain on solid and indicator
lamp 3 will flash as the system waits for the
vehicle to reduce speed. If vehicle speed is
reduced to, and kept below, 15 mph
(24 km/h) indicator lamp 4 will turn off and
indicator lamp 3 will flash until Entry/ExitMode is achieved at which point indicator
lamp 3 will go solid. If during the height
change to Entry/Exit Mode, the vehicle
speed exceeds 15 mph (24 km/h), the
height change will be paused until the
vehicle speed either goes below 15 mph
(24 km/h) and the height change continues
to Entry/Exit Mode, or exceeds 25 mph
(40 km/h) and the vehicle height will return
to NRH. Entry/Exit Mode may be selected
while the vehicle is not moving provided
that the engine is still running and all doors
remain closed.
• Transport Mode - No indicator lamps will be
illuminated. Customer driving will disable
Transport Mode.
• Tire/Jack Mode - Indicator lamps 3 and
6 will be illuminated. Customer driving will
disable Tire/Jack Mode.
• Wheel Alignment Mode - Indicator lamps
3 and 4 will be illuminated. Customer driv-
ing will disable Wheel Alignment Mode.SELEC-TERRAIN — IF
EQUIPPED
Selec-Terrain Mode Selection
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Selec-Terrain consists of the following posi-
tions:
•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 certain oper-
ating conditions), the transmission may use
second gear (rather than first gear) during
Selec-Terrain Switch
167

launches, to minimize wheel slippage. If
equipped with air suspension, the default
ride height for Snow is Normal Ride Height
(NRH).
•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. If
equipped with air suspension, the level will
change to Normal Ride Height (NRH).
•Sand– Off road calibration for use on low
traction surfaces such as sand or wet grass.
Driveline is maximized for traction. Some
binding may be felt on less forgiving sur-
faces. The electronic brake controls are set
to limit traction control management of
throttle and wheel spin. If equipped with
air suspension, the default ride height for
Sand is Normal Ride Height (NRH).
•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 trac-tion control management of throttle and
wheel spin. If equipped with air suspen-
sion, 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.

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 a
straight 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.
•L
aunch 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
you to adjust your launch RPM’s for opti-
mum launch/traction.3. Press the “Activate Launch Control” but-
ton on the touchscreen, follow instruc-
tions in the instrument cluster display.
• Make sure the vehicle is not moving.
• Put vehicle in first gear.
• Steering wheel must be pointing
straight.
• Vehicle must be on level ground.
• 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.
STARTING AND OPERATING
170

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.
NOTE:
After launch control has been aborted, ESC
will return to its current ESC mode.
CAUTION!
Do not attempt to shift when the drive
wheels are spinning and do not have trac-
tion. Damage to the transmission may oc-
cur.
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 flu-
ids are at the correct levels. Refer to “Fluid
Capacities” in “Technical Specifications”
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 procedure
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.
171

• 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.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 — IF
EQUIPPED
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h).
The Speed Control buttons are located on the
right side of the steering wheel.
STARTING AND OPERATING

NOTE:
In order to ensure proper operation, the
Speed Control System has been designed toshut 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.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Activate
Push the on/off button to activate the Speed
Control. “CRUISE CONTROL READY” will
appear in the instrument cluster display to

time. “CRUISE CONTROL OFF” will appear
in the instrument cluster display to indicate
the Speed Control is off. The system should
be turned off when not in use.
WARNING!
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.
To Set 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 when the speed is set.

ADAPTIVE CRUISE
CONTROL (ACC) — IF
EQUIPPEDIf your vehicle is equipped with Adaptive
Cruise Control, the controls operate exactly
the same as 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.
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.
To Activate/Deactivate
Push and release the Adaptive Cruise Control
(ACC) on/off button. The ACC menu in the
instrument cluster displays “ACC Ready.”
