2013 JEEP GRAND CHEROKEE change time

Pressing the “DOWN” button once will move the
suspension one position lower from the current
level, assuming all conditions are met (i.e. en-
gine running, doors closed, speed below
threshold, etc). The “DOWN” button can be
pressed multiple times. Each press will lower
the requested level by one position down to a
minimum of Park Mode or the lowest position
allowed based on current conditions (i.e. ve-
hicle speed, etc.)
Automatic height changes will occur based on
vehicle speed and the current vehicle height.
The indicator lamps and EVIC messages will
operate the same for automatic changes and
user requested 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. •
Park Mode – Indicator lamp 3 will be illumi-
nated when the vehicle is in Park Mode. If
Park 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
Park Mode is achieved at which point indica-
tor lamp 3 will go solid. If during the height
change to Park 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 Park Mode, or
exceeds 25 mph (40 km/h) and the vehicle
height will return to NRH. Park Mode may be
selected while the vehicle is not moving
provided that the engine is still running and
all doors remain closed.ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance
and a narrower track to make them capable of
performing in a wide variety of off-road applica-
tions. Specific design characteristics give them
a higher center of gravity than ordinary cars.
An advantage of the higher ground clearance is
a better view of the road, allowing you to
anticipate problems. They are not designed for
cornering at the same speeds as conventional
two-wheel drive vehicles any more than low-
slung sports cars are designed to perform sat-
isfactorily in off-road conditions. If at all pos-
sible, avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to
operate this vehicle correctly may result in loss
of control or vehicle rollover.

CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering, as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
new vehicle limited warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle. If you must drive through water, try to
determine the depth and the bottom condition
(and location of any obstacles) prior to entering.
Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in
deep water to minimize wave effects.Flowing Water
If the water is swift flowing and rising (as in
storm run-off), avoid crossing until the water
level recedes and/or the flow rate is reduced. If
you must cross flowing water avoid depths in
excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle
to sink into deeper water. Determine exit
point(s) that are downstream of your entry point
to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed appropri-
ately to minimize wave effects. Maximum speed
in 20 inches (51 cm) of water is less than 5 mph
(8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil, trans-
mission oil, axle, transfer case) to assure the
fluids have not been contaminated. Contami-
nated fluid (milky, foamy in appearance) should
be flushed/changed as soon as possible to
prevent component damage.
Driving In Snow, Mud And SandIn heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Oper-
ating” for further information. Do not shift to a
lower gear than necessary to maintain forward
motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine
the conditions at the crest and/or on the
other side.
Before climbing a steep hill,
shift the trans-
mission to a lower gear and shift the transfer
case to 4WD LOW. Use first gear and 4WD
LOW for very steep hills.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include an adaptive
drive strategy to avoid frequent shifting when
towing. However, if frequent shifting does occur
while in DRIVE, select TOW mode, or use the
AutoStick® shift control to select a lower gear.
NOTE:
Using TOW mode or selecting a lower gear
while operating the vehicle under heavy load-
ing conditions, will improve performance and
extend transmission life by reducing exces-
sive shifting and heat buildup. This action will
also provide better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then change
the transmission fluid and filter(s) as specified for
"police, taxi, fleet, or frequent trailer towing. Refer
to the “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experi-
ence 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 en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

CAUTION!
•
Failure to properly maintain your vehicle or
perform repairs and service when necessary
could result in more costly repairs, damage
to other components or negatively impact
vehicle performance. Immediately have po-
tential malfunctions examined by an autho-
rized dealer or qualified repair center.
•Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by
the New Vehicle Limited Warranty. If a
flush is needed because of component
malfunction, use only the specified fluid for
the flushing procedure.
Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at the
correct level. The best time to check the engine
oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the SAFE level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine. Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.

WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised when
filling or working around the washer solution.
Exhaust SystemThe best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under-
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete ex-
haust system and adjacent body areas for bro-
ken, damaged, deteriorated, or mispositioned
parts. Open seams or loose connections could
permit exhaust fumes to seep into the passen-
ger compartment. In addition, have the exhaust
system inspected each time the vehicle is
raised for lubrication or oil change. Replace as
required.
WARNING!
•Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips/Exhaust Gas” in “Things To
Know Before Starting Your Vehicle” for
further information.
• A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.CAUTION!
•The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri-
ously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor-
mance, have your vehicle serviced
promptly. Continued operation of your ve-
hicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic
converter will not require maintenance. How-
ever, it is important to keep the engine properly
tuned to assure proper catalyst operation and
prevent possible catalyst damage.

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
and reliability. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very short
trip driving. Inspection and service should also
be done anytime a malfunction is suspected.
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 illuminate
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 ex-
tended 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 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.
