2018 JEEP GRAND CHEROKEE ignition

4. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump-starting proce-
dure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged ve-
hicle.NOTE:
Make sure at all times that unused ends of
jumper cables are not contacting each other
or either vehicle while making connections.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system tested at your authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
Cable Connection
1. Connect the positive(+)end of the jumper
cable to the remote positive(+)post of the
discharged vehicle.2. Connect the opposite end of the positive
(+)jumper cable to the positive(+)post of
the booster battery.
3. Connect the negative end(-)of the jumper
cable to the negative(-)post of the
booster battery.
4. Connect the opposite end of the negative
(-)jumper cable to the remote negative(-)
post of the vehicle with the discharged
battery.
WARNING!
Do not connect the jumper cable to the
negative(-)post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few
minutes, and then start the engine in the
vehicle with the discharged battery.

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 manufac-
turer’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 bumpers or associated brack-
ets. 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 ON/RUN mode, not ACC mode.
If the vehicle's battery is discharged, refer to
“Manual Park Release” in this section for
instructions on shifting the transmission out
of PARK for towing.
CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
CAUTION!
• When securing the vehicle to a flatbed
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 steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the LOCK/
OFF mode.
IN CASE OF EMERGENCY
224

Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheelsOFFthe ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with rear wheels on the ground) under
the following conditions:
• The transmission must be in NEUTRAL.
Refer to "Manual Park Release" in this sec-
tion for instructions on shifting the trans-
mission to NEUTRAL when the engine is
off.
• The towing speed must not exceed 30 mph
(48 km/h).• The towing distance must not exceed
30 miles (48 km).
If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
tow with the rear wheelsOFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with the front wheels raised and
the rear wheels on a towing dolly, or (when
using a suitable steering wheel stabilizer to
hold the front wheels in the straight position)
with the rear wheels raised and the front
wheels on the ground.
CAUTION!
• Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe
transmission damage. Damage from im-
proper towing is not covered under the
New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of vehicle raised and the opposite
end on a towing dolly.
If flatbed equipment is not available, and the
transfer case is operable, vehicleswith a
two-speed transfer casemay be towed (in the
forward direction, withALLwheels on the
ground),IFthe transfer case is in NEUTRAL
(N) and the transmission is inPARK. Refer to
“Recreational Towing” in “Starting And Op-
erating” in the Owner’s Manual for detailed
instructions.
Vehicles equipped with a single-speed trans-
fer case have no NEUTRAL position, and
thereforemustbe towed with all four wheels
OFFthe ground.

had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh OAT coolant (conforming to
MS.90032) by an authorized dealer. Check
the front of the A/C condenser for any accu-mulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-
tire system for leaks. DO NOT REMOVE THE
COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.

BODYWORK
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash
your vehicle in the shade using a mild car
wash soap, and rinse the panels completely
with clear water.
• Use a high quality cleaner wax to remove
road film, stains and to protect your paint
finish. Take care never to scratch the paint.
• Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin
out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder that will scratch metal and
painted surfaces.
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
Special Care
• If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar-
riage at least once a month.
• It is important that the drain holes in the
