2005 JEEP GRAND CHEROKEE hazard

After Driving Off-Road
Off-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, steering, suspension, and
exhaust system for damage.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. 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.
•After extended operation in mud, sand, water, or
similar dirty conditions, have 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 an accident. 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. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. Use it when
your vehicle is disabled on or near the road. It warns
other drivers to steer clear of you and your vehicle. This
is an emergency warning system, not to be used when the
vehicle is in motion.
To activate the warning flasher, push down on the button
on top of the steering column until it latches. To turn the
warning flasher off, push down again to unlatch the
button.
NOTE:With extended use, the flasher may run down
your battery.

296 WHAT TO DO IN EMERGENCIES

Preparations For Jacking
Park the vehicle on a firm level surface, avoid ice or
slippery areas,set the parking brakeand place the gear
selector in P (Park). Turn OFF the ignition.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.
For example, if changing the
right front tire, block the left
rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove the spare tire, jack, and tools from storage.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
300 WHAT TO DO IN EMERGENCIES

If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the
vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Maintenance After Off-Pavement Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake discs, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
Following off-pavement usage, completely inspect the
underbody of your vehicle. Check tires, body structure,
steering, suspension and exhaust system for damage.
Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering and suspen-
sion. Retighten, if required, to torque values specified in
the Service Manual. Also check for accumulations ofvegetation or brush that could become a fire hazard, or
conceal damage to fuel lines, brake hoses, axle pinion
seals, and propeller shafts.
CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service to prevent excessive
wear.
344 MAINTAINING YOUR VEHICLE

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove fuse #27 in the Intelligent Power Module
labeled Ignition-Off Draw (IOD#1).
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
