2013 JEEP GRAND CHEROKEE suspension

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.

OFF-ROAD DRIVING TIPS
NOTE:
Prior to off-road driving, remove the front air
dam to prevent damage. The front air dam is
attached to the lower front fascia with seven
quarter turn fasteners and can be removed
by hand.
Quadra-Lift™ – If EquippedWhen off-roading, it is recommended that the
lowest useable vehicle height that will clear the
current obstacle or terrain be selected. The
vehicle height should then be raised as required
by the changes in terrain.
The Selec-Terrain™ switch will automatically
change the vehicle to the optimized height
based on the Selec-Terrain™ switch position.
The vehicle height can be changed from the
default height for each Selec-Terrain™ mode by
normal use of the air suspension switches.
Refer to “Quadra-Lift™ – If Equipped” in “Start-
ing and Operating” for further information.
When To Use 4WD LOW Range – If
Equipped
When off-road driving, shift to 4WD LOW for
additional traction. This range should be limited
to extreme situations such as deep snow, mud,
or sand where additional low speed pulling
power is needed. Vehicle speeds in excess of
25 mph (40 km/h) should be avoided when in
4WD LOW range.
WARNING!
Do not drive in 4WD-LOW Range on dry
pavement; driveline damage may result.
4WD-LOW Range locks front and rear driv-
elines together and does not allow for differ-
ential action between the front to rear drive-
shafts. Driving in 4WD-LOW on pavement
will cause driveline binding and"crow-hop";
use only on wet or slippery surfaces.
Driving Through WaterAlthough your vehicle is capable of driving
through water, there are a number of precau-
tions that must be considered before entering
the water.
NOTE:
Your vehicle is capable of water fording in
up to 20 inches (51 cm) of water, while
crossing small rivers or streams. To main-
tain optimal performance of your vehicle’s
heating and ventilation system it is recom-
mended to switch the system into recircula-
tion mode during water fording.

If you stall or begin to lose forward motion
while climbing a steep hill, allow your vehicle to
come to a stop and immediately apply the
brakes. Restart the engine, and shift into RE-
VERSE. Back slowly down the hill, allowing the
compression braking of the engine to help regu-
late your speed. If the brakes are required to
control vehicle speed, apply them lightly and
avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion,
or cannot make it to the top of a steep hill or
grade, never attempt to turn around. To do so
may result in tipping and rolling the vehicle.
Always back carefully straight down a hill in
REVERSE gear. Never back down a hill in
NEUTRAL using only the brake.Remember, never drive diagonally across a
hill always drive straight up or down.
If the wheels start to slip as you approach the
crest of a hill, ease off the accelerator and
maintain forward motion by turning the front
wheels slowly. This may provide a fresh “bite”
into the surface and will usually provide traction
to complete the climb.Traction DownhillShift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the
vehicle go slowly down the hill with all four
wheels turning against engine compression
drag. This will permit you to control the vehicle
speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of
braking control. Avoid repeated heavy braking
by downshifting the transmission whenever
possible.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
•
Completely inspect the underbody of your ve-
hicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
•
Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness, par-
ticularly on the chassis, drivetrain compo-
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
• Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.

Life Of TireThe service life of a tire is dependent upon
varying factors including, but not limited to:
•Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of
V or higher, and summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle maintenance schedule is
highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in seri-
ous injury or death.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement TiresThe tires on your new vehicle provide a balance
of many characteristics. They should be in-
spected regularly for wear and correct cold tire
inflation pressure. The manufacturer strongly
recommends that you use tires equivalent to the
originals in size, quality and performance when
replacement is needed. Refer to the paragraph
on “Tread Wear Indicators”. Refer to the “Tire
and Loading Information” placard for the size
designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the
original equipment tire sidewall. See the Tire
Sizing Chart example found in the Tire Safety
Information section of this manual for more
information relating to the Load Index and
Speed Symbol of a tire.
It is recommended to replace the two front tires
or two rear tires as a pair. Replacing just one tire
can seriously affect your vehicle’s handling. If
you ever replace a wheel, make sure that the
wheel’s specifications match those of the origi-
nal wheels. It is recommended you contact your authorized
tire or original equipment vehicle dealer with
any questions you may have on tire specifica-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
WARNING!
•
Do not use a tire, wheel size or rating other
than that specified for your vehicle. Some
combinations of unapproved tires and
wheels may change suspension dimen-
sions and performance characteristics, re-
sulting in changes to steering, handling,
and braking of your vehicle. This can
cause unpredictable handling and stress
to steering and suspension components.
You could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.

WARNING!(Continued)
•Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with
a smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can re-
sult in sudden tire failure and loss of ve-
hicle control.
CAUTION!
Replacing original tires with tires of a differ-
ent size may result in false speedometer and
odometer readings.
TIRE CHAINS (TRACTION
DEVICES)
Use of traction devices require sufficient tire-to-
body clearance. Follow these recommenda-
tions to guard against damage.
• Traction device must be of proper size for the
tire, as recommended by the traction device
manufacturer.
• Install on Rear Tires Only
• Due to limited clearance, use reduced size
snow chains or traction devices with a maxi-
mum projection of 6 mm beyond the tire
profile.
WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
•Because of restricted traction device clear-
ance between tires and other suspension
components, it is important that only trac-
tion devices in good condition are used.
Broken devices can cause serious dam-
age. Stop the vehicle immediately if noise
occurs that could indicate device break-
age. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
• Do not drive for prolonged period on dry
pavement.

Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to bum-
pers or associated brackets. State and local
laws regarding vehicles under tow must be
observed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If the vehicle’s battery is discharged, see “Shift
Lever Override” in “What To Do In Emergen-
cies” for instructions on shifting the automatic
transmission out of PARK for towing.
CAUTION!
•
Do not use sling type equipment when
towing. When securing the vehicle to a flat
bed truck, do not attach to front or rear
suspension components. Damage to your
vehicle may result from improper towing.
•
If the vehicle being towed requires steering,
the ignition must be in the ON/RUN or ACC
position, not in the LOCK/OFF position.

Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with MOPAR® Glass Cleaner, or
any commercial household-type glass cleaner.
Never use an abrasive type cleaner. Use cau-
tion when cleaning the inside rear window
equipped with electric defrosters or the right
rear quarter window equipped with the radio
antenna. Do not use scrapers or other sharp
instrument that may scratch the elements.
When cleaning the rear view mirror, spray
cleaner on the towel or rag that you are using.
Do not spray cleaner directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When clean-
ing the lenses, care must be taken to avoid
scratching the plastic.
1. Clean with a wet soft rag. A mild soap
solution may be used, but do not use high
alcohol content or abrasive cleaners. If soap is
used, wipe clean with a clean damp rag.
2. Dry with a soft cloth.Seat Belt Maintenance
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This will
weaken the fabric. Sun damage can also
weaken the fabric.
If the belts need cleaning, use a mild soap
solution or lukewarm water. Do not remove the
belts from the car to wash them. Dry with a soft
cloth.
Replace the belts if they appear frayed or worn
or if the buckles do not work properly.
