2020 JEEP GRAND CHEROKEE check engine

This wearing in occurs mainly during the first
500 miles (805 km) and continues through
the first oil change interval.
It is recommended for the operator to observe
the following driving behaviors during the
new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle
for an extended period of time.
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration.
• Avoid aggressive braking.
• Drive with the engine speed less than
3,500 RPM.
• Maintain vehicle speed below 55 mph
(88 km/h) and observe local speed limits.
100 to 300 miles (161 to 483 km):
• Depress the accelerator pedal slowly and
not more than halfway to avoid rapid accel-
eration in lower gears (1st to 3rd gears).
• Avoid aggressive braking.• Drive with the engine speed less than
5,000 RPM.
• Maintain vehicle speed below 70 mph
(112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shifting
manually (paddles or gear shift) at higher
rpms when possible.
• Do not perform sustained operation with
the accelerator pedal at wide open throttle.
• Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1500 miles (2414 km):
• Do not participate in track events, sport
driving schools, or similar activities during
the first 1500 mi (2414 km).
NOTE:
Check engine oil with every refueling and add
if necessary. Oil and fuel consumption may
be higher through the first oil change inter-
val. Running the engine with an oil level
below the add mark can cause severe engine
damage.AUTOMATIC
TRANSMISSION
WARNING!
•Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when exiting the ve-
hicle to guard against vehicle movement
and possible injury or damage.
•Your vehicle could move and injure you and
others if it is not in PARK. Check by trying
to move the transmission gear selector out
of PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.
•The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting
to PARK, and verify that the transmission
gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the
PARK position is properly indicated, before
exiting the vehicle.

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.

WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView
should only be used as a parking aid.
The ParkView camera is unable to view
every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle
must be driven slowly when using
ParkView to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/
her shoulder when using ParkView.NOTE:
If snow, ice, mud, or any foreign substance
builds up on the camera lens, clean the lens,
rinse with water, and dry with a soft cloth. Do
not cover the lens.
Rear Camera — Viewing At Speed
When the vehicle is in park, neutral or drive,
the Rear View Camera can be activated with
the “Rear View Camera” button in the Con-
trols menu. This feature allows the customer
to monitor the area directly behind the ve-
hicle (or trailer, if equipped) for up to ten
seconds while at speed. If the vehicle speed
remains below 8 mph (13 km/h), the Rear
View Camera image will be displayed con-
tinuously until deactivated via the “X” button
on the touchscreen.

FUSES
WARNING!
•When replacing a blown fuse, always use
an appropriate replacement fuse with the
same amp rating as the original fuse. Never
replace a fuse with another fuse of higher
amp rating. Never replace a blown fuse
with metal wires or any other material. Do
not place a fuse inside a circuit breaker
cavity or vice versa. Failure to use proper
fuses may result in serious personal injury,
fire and/or property damage.
•Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
•If the replaced fuse blows again, contact
an authorized dealer.
•If a general protection fuse for safety sys-
tems (air bag system, braking system),
power unit systems (engine system, trans-
mission system) or steering system blows,
contact an authorized dealer.
CAUTION!
If it is necessary to wash the engine com-
partment, take care not to directly hit the
fuse box, and the windshield wiper motors
with water.
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, micro
fuses, relays, and circuit breakers. A descrip-tion of each fuse and component may be
stamped on the inside cover, otherwise the
cavity number of each fuse is stamped on the
inside cover that corresponds to the following
chart.
NOTE:
Fuses for safety systems (marked with *)
must be serviced by an authorized dealer.

SCHEDULED SERVICING
Scheduled Servicing — Non SRT
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, as described in the Scheduled Servicing
plan. To keep the car’s efficiency in tip-top
condition, in the following Scheduled Service
plan pages a few additional checks are listed
that should be carried out more frequently
with respect to the normal coupon redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones
scheduled, the need arises for further re-
placements or repairs, these may be carried
out with the owner's explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and me-
chanical tools that can help prevent futurecostly repairs. If your car is used frequently
for towing, the interval between one sched-
uled servicing operation and the next should
be reduced. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very
short trip driving.
NOTE:
Scheduled Servicing interventions are set out
by the Manufacturer. Failure to have them
carried out may invalidate the warranty. It is
advised to inform an authorized dealership of
any small operating irregularities without
waiting for the next service.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
In the instrument cluster an “Oil Change
Required” message will be displayed and a
single chime will sound, indicating that an oil
change is necessary.The oil change indicator message will illumi-
nate approximately 7,000 miles
(11,200 km) after the most recent oil change
was performed. Have your vehicle serviced as
soon as possible, within 500 miles (800 km).
NOTE:
• The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change
intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this scheduled
oil change is performed by someone other
than your authorized dealer the message can
