power steering JEEP GRAND CHEROKEE 2010 Owner handbook (in English)

•If the liftgate handle is pulled while the
power liftgate is closing, the liftgate will
reverse to the full open position.
• If the liftgate handle is pulled while the
power liftgate is opening, the liftgate mo-
tor will disengage to allow manual opera-
tion.
• The power liftgate buttons will not oper-
ate if the vehicle is in gear or the vehicle
speed is above 0 mph (0 km/h).
• The power liftgate will not operate in tem-
peratures below 22°F ( 30°C) or tem-
peratures above 150°F (65°C). Be sure to
remove any buildup of snow or ice from
the liftgate before pressing any of the
power liftgate switches.
•
If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop and the lift-
gate must be opened or closed manually.
• If your liftgate is power closing and you
put the vehicle in gear, the liftgate will
continue to power close. However, ve-
hicle movement may result in a detection
of an obstruction.
WARNING!
• Driving with the liftgate open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured
by these fumes. Keep the liftgate closed
when you are operating the vehicle.
• If you are required to drive with the liftgate
open, make sure that all windows are
closed, and the climate control blower
switch is set at high speed. Do not use the
recirculation mode.
Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
OCCUPANT RESTRAINTSSome of the most important safety features in
your vehicle are the restraint systems:
• Three-point lap and shoulder belts for the
driver and all passengers •
Advanced Front Airbags for driver and front
passenger
• Supplemental Active Head Restraints (AHR)
located on top of the front seats (integrated
into the head restraint)
• Supplemental driver side knee airbag
• Supplemental Side Airbag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window — if equipped
• Supplemental Seat-Mounted Side Airbags
(SAB) — if equipped
• An energy-absorbing steering column and
steering wheel
• Knee bolsters/blockers for front seat occu-
pants
• Front seat belts incorporate pretensioners to
enhance occupant protection by managing
occupant energy during an impact event
•
All seat belt systems (except the driver’s)
include Automatic Locking Retractors (ALRs),
which lock the seat belt webbing into position
by extending the belt all the way out and then

WARNING!(Continued)
• Never put floor mats or other floor cover-
ings on top of already installed floor mats.
Additional floor mats and other coverings
will reduce the size of the pedal area and
interfere with the pedals.
• Check mounting of mats on a regular basis.
Always properly reinstall and secure floor
mats that have been removed for cleaning.
• Always make sure that objects cannot fall
into the driver foot well while the vehicle is
moving. Objects can become trapped un-
der the brake pedal and accelerator pedal
causing a loss of vehicle control.
(Continued)WARNING!(Continued)
• If required, mounting posts must be prop-
erly installed, if not equipped from the fac-
tory.
Failure to properly follow floor mat installation
or mounting can cause interference with the
brake pedal and accelerator pedal operation
causing loss of control of the vehicle.
Periodic Safety Checks You Should
Make Outside the Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread.
Inspect the tread and sidewall for cuts and
cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper
pressure. Lights
Have someone observe the operation of exte-
rior lights while you work the controls. Check
turn signal and high beam indicator lights on
the instrument panel.
Door Latches
Check for positive closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located
and corrected immediately.

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
vehicle. Check tires, body structure, steer-
ing, suspension, and exhaust system for
damage.
• Inspect the radiator for mud and debris and
clean as required.
• Check threaded fasteners for looseness,
particularly on the chassis, drivetrain com-
ponents, steering, and suspension. Re-
tighten 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.
• After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the ra-
diator, fan, brake rotors, wheels, brake lin-
ings, 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 collision. If you
have been operating your vehicle in dirty
conditions, get your brakes checked and
cleaned as necessary.
• If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material. Im-
pacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
POWER STEERING
3.6L Engine and 3.0L Diesel Engine
Your 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 the
electro-hydraulic power steering system expe-
riences 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
220

dealer for service. It is likely the vehicle has lost
power steering assistance. Refer to “Electronic
Vehicle Information (EVIC)” in “Understanding
Your Instrument Panel” for further 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
steering effort, especially at very low ve-
hicle speeds and during parking maneu-
vers. •
If the condition persists, see your autho-
rized dealer for service.
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
during 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.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 in-
crease the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.
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 sus-
pected, abnormal noises are apparent, and/or
the system is not functioning as anticipated.
Coordinate inspection efforts through an autho-
rized dealer.
