check engine light JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can dam-
age your power steering components. Such
damage is not covered by the New Vehicle
Limited Warranty.
WARNING!
Fluid level should be checked on a level
surface and with the engine off to prevent
injury from moving parts and to ensure accu-
rate fluid level reading. Do not overfill. Use
only manufacturer’s recommended power
steering fluid.
If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids,
Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
MULTI-DISPLACEMENT SYSTEM
(MDS) (IF EQUIPPED) — 5.7L
ENGINE ONLY
This feature offers improved fuel economy by
shutting off four of the engine’s eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
The MDS system may take some time to
return to full functionality after a battery
disconnect.
PARKING BRAKEBefore leaving the vehicle, make sure that the
parking brake is fully applied and place the
shift lever in the PARK position.
The foot operated parking brake is located
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
park brake pedal fully. To release the parking
brake, press the park brake pedal a second
time and let your foot up as you feel the brake
disengage. When the parking brake is applied with the
ignition switch in the ON position, the “Brake
Warning Light” in the instrument cluster will
illuminate.
NOTE:
•
When the parking brake is applied and the
transmission is placed in gear, the “Brake
Warning Light” will flash. If vehicle speed
is detected, a chime will sound to alert the
driver. Fully release the parking brake
before attempting to move the vehicle.

sive shifting and heat buildup. This action
will also provide better engine braking.
The transmission fluid and filter should be
changed if you REGULARLY tow a trailer for
more than 45 minutes of continuous operation.
Refer to “Maintenance Schedule” for the proper
maintenance intervals.
NOTE:
Check the transmission fluid level before
towing (5.7L engine).
To help maintain a comfortable operating
temperature for your transmission, it is rec-
ommended that when towing a maximum
loaded trailer up steep grades with switch
backs, you should use the ERS function on
the transmission shifter to lock your vehicle
into first gear (5.7L Models Only).
Electronic Speed Control – If Equipped
Do not use in hilly terrain or with heavy loads.
When using the speed control, if you expe-rience speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed. Use speed control in flat terrain and with light
loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift
the transmission into NEUTRAL and increase
engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
Trailer Hitch Attaching Points
Your vehicle will require extra equipment to tow
a trailer safely and efficiently. The trailer tow
hitch must be attached to your vehicle using
the provided attaching points on the vehicle’s
frame. Refer to the following chart to determine
the accurate attaching points. Other equip-
ment, such as trailer sway controls and braking
equipment, trailer equalizing (leveling) equip-
ment and low profile mirrors, may also be
required or strongly recommended.
Trailer Tow Hitch Attaching Points And Overhang Dimensions
Fixed, Detach
and Retractable Hitch
A 1.85 ft. (565 mm)
B 2.09 ft. (636 mm)
C 2.32 ft. (707 mm)
D 2.4 ft. (733 mm)
E 1.62 ft. (494 mm)
F 1.47 ft. (447 mm)

The Keyless Enter-N-Go button (if equipped)
may now be reinstalled if desired. Refer to “Start- ing Procedures/Keyless Enter-N-Go” in “Starting
and Operating” for further information.
NOTE:
•
Steps 1 through 7 are requirements that
must be met prior to pressing the NEU-
TRAL (N) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
prior to pressing the NEUTRAL (N) button
or are no longer met during the shift, the
NEUTRAL (N) indicator light will flash
continuously until all requirements are
met or until the NEUTRAL (N) button is
released. •
The ignition switch must be in the ON/
RUN position for a shift to take place and
for the position indicator lights to be op-
erable. If the ignition switch is not in the
ON/RUN position, the shift will not take
place and no position indicator lights will
be on or flashing.
• A flashing NEUTRAL (N) position indica-
tor light indicates that shift requirements
have not been met.

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-
quired” will be displayed in the EVIC 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 per-
formed. 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
6 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 ex-
tended period of time.
• Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.
At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required. Once a Month
•
Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required.
• Check the fluid levels of the coolant reser-
voir, brake master cylinder, power steering
and transmission (5.7L only) and add as
needed.
• Check all lights and other electrical items for
correct operation.

intervals exceed 12,500 miles (20 000 km) or
12 months, whichever comes first.
At Each Stop for Fuel
• Check the engine oil level about 15 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is on
level ground will improve the accuracy of the
oil level reading. Add oil only when the level
is at or below the ADD or MIN mark.
• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required. •
