2013 JEEP GRAND CHEROKEE engine

4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster will
flash and go out when the shift is complete.
NOTE:
•If shift conditions/interlocks are not met,
or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 MPH or 5 KPH Put Trans in
N Press 4 Low” message will flash from
the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding
Your Instrument Panel” for further infor-
mation. •Shifting into or out of 4WD LOW is possible
with the vehicle completely stopped; how-
ever, difficulty may occur due to the mating
clutch teeth not being properly aligned.
Several attempts may be required for clutch
teeth alignment and shift completion to
occur. The preferred method is with the
vehicle rolling 0 to 3 mph (0 to 5 km/h). If the
vehicle is moving faster than 3 mph
(5 km/h), the transfer case will not allow the
shift.
NEUTRAL Shift Procedure
1. Turn the ignition switch to the ON position,
engine off.
2. Vehicle stopped, with foot on brake.
3. Place the transmission into NEUTRAL.
4. Hold down the NEUTRAL “pin” switch (with a
pen, etc.) for four seconds until the LED light by
the switch starts to blink indicating shift in
progress. The light will stop blinking (stay on
solid) when the NEUTRAL shift is complete.
5. Repeat Steps 1 to 4 to shift out of NEU-
TRAL.
NOTE:
If shift conditions/interlocks are not met, a
“To Tow Vehicle Safely, Read Neutral Shift
Procedure in Owners Manual” message will
flash from the Electronic Vehicle Informa-
tion Center (EVIC). Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further
information.Neutral Switch

The system requires that the engine be running
for all changes. When lowering the vehicle all of
the doors, including the liftgate, must be closed.
If a door is opened at any time while the vehicle
is lowering the change will not be completed
until the open door(s) is closed.
The Quadra-Lift™ air suspension system uses
a lifting and lowering pattern which keeps the
headlights from incorrectly shining into oncom-
ing traffic. When raising the vehicle, the rear of
the vehicle will move up first and then the front.
When lowering the vehicle, the front will move
down first and then the rear.
After the engine is turned off, it may be noticed
that the air suspension system operates briefly,
this is normal. The system is correcting the
position of the vehicle to ensure a proper ap-
pearance.
To assist with changing a spare tire, the
Quadra-Lift™ air suspension system has a fea-
ture which allows the automatic leveling to be
disabled. Press and hold both the “Up” and
“Down” buttons simultaneously between 5 and
10 seconds, a message will appear in the EVIC
stating leveling has been disabled immediatelyafter both buttons have been released. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information. Driving the vehicle over
5 mph (8 km/h) will return the air suspension to
normal operation. Refer to “Jacking and Tire
Changing” in “What To Do In Emergencies” for
further information.
WARNING!
The air suspension system uses a high pres-
sure volume of air to operate the system. To
avoid personal injury or damage to the sys-
tem, see your authorized dealer for service.
Electronic Vehicle Information
Center (EVIC) Display Messages
When the appropriate conditions exist, a mes-
sage will appear in the EVIC display. Refer to
“Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for
further information.
An audible chime will be heard whenever a
system error has been detected.
OperationThe indicator lamps 3 through 6 will illuminate to
show the current position of the vehicle. Flash-
ing indicator lamps will show a position which
the system is working to achieve. When raising,
if multiple indicator lamps are flashing on the
“Up” button, the highest flashing indicator lamp
is the position the system is working to achieve.
When lowering, if multiple indicators are flash-
ing on the
"Up"button the lowest solid indicator
lamp is the position the system is working to
achieve.
Pressing the “UP” button once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.
engine running, speed below threshold, etc).
The “UP” button can be pressed multiple times,
each press will raise the requested level by one
position up to a maximum position of OR2 or the
highest position allowed based on current con-
ditions (i.e. vehicle speed, etc).
243

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.
246

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.
247

•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a colli-
sion. If you have been operating your vehicle
in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driv-
ing in mud, slush or similar conditions, check
the wheels for impacted material. Impacted
material can cause a wheel imbalance and
freeing the wheels of it will correct the
situation.
FUEL SAVER TECHNOLOGY
5.7L ENGINE ONLY – IF
EQUIPPED
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:
This system may take some time to return to
full functionality after a battery disconnect.
POWER STEERING
3.6L And 5.7L EngineThe standard power steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost. If for some reason the power assist is inter-
rupted, it will still be possible to steer your
vehicle. Under these conditions, you will ob-
serve a substantial increase in steering effort,
especially at very low vehicle speeds and dur-
ing parking maneuvers.
NOTE:
•
Increased noise levels at the end of the
steering wheel travel are considered nor-
mal and do not indicate that there is a
problem with the power steering system.
• Upon initial start-up in cold weather, the
power steering pump may make noise for
a short amount of time. This is due to the
cold, thick fluid in the steering system.
This noise should be considered normal,
and it does not in any way damage the
steering system.
248

WARNING!
Continued operation with reduced power
steering assist could pose a safety risk to
yourself and others. Service should be ob-
tained as soon as possible.
CAUTION!
Prolonged operation of the steering system
at the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage
to the power steering pump may occur.
3.0L Diesel EngineYour vehicle is equipped with an electro-
hydraulic power steering system that will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will vary its assist to provide light efforts while
parking and good feel while driving. If theelectro-hydraulic power steering system experi-
ences a fault that prevents it from providing
power steering assist, then the system will
provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the
electrically driven pump to reduce or stop
power steering assistance in order to prevent
damage to the system. Normal operation will
resume once the system is allowed to cool.
If the “SERVICE POWER STEER-
ING SYSTEM” message and a
flashing icon are displayed on the
EVIC screen, it indicates that the
vehicle needs to be taken to the
dealer for service. It is likely the
vehicle has lost power steering assistance. Re-
fer to “Electronic Vehicle Information (EVIC)” in
“Understanding Your Instrument Panel” for fur-
ther information. If the “POWER STEERING SYSTEM OVER
TEMP” message and an icon are displayed on
the EVIC screen, it indicates that extreme steer-
ing maneuvers may have occurred, which
caused an over temperature condition in the
power steering system. You will lose power
steering assistance momentarily until the over
temperature condition no longer exists. Once
driving conditions are safe, then pull over and
let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Informa-
tion (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•
Even if power steering assistance is no
longer operational, it is still possible to
steer the vehicle. Under these conditions
there will be a substantial increase in steer-
ing effort, especially at very low vehicle
speeds and during parking maneuvers.
•
If the condition persists, see your autho-
rized dealer for service.

Power Steering Fluid CheckChecking the power steering fluid level at a
defined service interval is not required. The fluid
should only be checked if a leak is suspected,
abnormal noises are apparent, and/or the sys-
tem is not functioning as anticipated. Coordi-
nate inspection efforts through an authorized
dealer.
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 sur-
face and with the engine off to prevent injury
from moving parts and to ensure accurate fluid
level reading. Do not overfill. Use only manu-
facturer’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.
PARKING BRAKE
Before 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.
