engine JEEP GRAND CHEROKEE 2014 WK2 / 4.G Service Manual

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the potential for overheating by
taking the appropriate action:
• On the highways — slow down.
• In city traffic — while stopped, shift the transmission to NEUTRAL, but do not
increase engine idle speed.
NOTE:
There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the
engine cooling system and turning the A/C off can help remove this heat.
•
You can also turn the temperature control to maximum heat, the mode control to floor
and the blower control to high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into the normal range. If the
pointer remains on HOT (H), and you hear continuous chimes, turn the engine off
immediately, and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never try to open a cooling system
pressure cap when the radiator or coolant bottle is hot.
JACKING AND TIRE CHANGING
Run Flat Tires — SRT Only
This vehicle is equipped with “run flat” tires. Run flat tires allow the vehicle to be
driven approximately 50 miles (80km) at 55 mph (88km/h). Tire service should be
obtained to avoid prolonged run flat feature usage.
NOTE:
This vehicle may be equipped with a spare tire. The spare tire must be used for the
rear wheel(s) only. For a flat front tire, move the rear tire to the front and use the spare
tire on the rear.

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 the danger of being hit when
operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack
should not be used to lift the vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or slippery areas.
• Always park on a firm, level surface as far from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this vehicle during
a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be
stowed with the valve stem facing the ground.
• Carefully follow these tire changing warnings to help prevent personal injury or
damage to your vehicle.
• Raising the vehicle higher than necessary can make the vehicle less stable. It
could slip off the jack and hurt someone near it. Raise the vehicle only enough
to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the wheel
nuts fully until the vehicle has been lowered. Failure to follow this warning may
result in personal injury.
• A loose tire or jack, thrown forward in a collision or hard stop could endanger
the occupants of the vehicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire repaired or replaced imme-
diately.

BATTERY LOCATION
The battery in your vehicle is located under the passenger's front seat. Remote
battery posts are located on the right side of the engine compartment for jump-
starting.
JUMP-STARTING
If your vehicle has a discharged battery it can be jump-started using a set of jumper
cables and a battery in another vehicle or by using a portable battery booster pack.
Jump-starting can be dangerous if done improperly so please follow the procedures
in this section carefully.
NOTE:
When using a portable battery booster pack follow the manufacturer’s operating
instructions and precautions.
Preparations For Jump-Start
The battery in your vehicle is located
under the passengers front seat. There
are remote locations under the hood to
assist in jump starting.
1. Set the parking brake, shift the auto-
matic transmission into PARK and
turn the ignition to LOCK.
2. Turn off the heater, radio, and all
unnecessary electrical accessories.
3. Remove the protective cover over the
remote positive (+) battery post. Pull
upward on the cover to remove it.
4. If using another vehicle to jump-start
the battery, park the vehicle within
the jumper cables reach, set the park-
ing brake and make sure the ignition
is OFF.

Jump-Starting Procedure
1. Connect the positive(+)end of the jumper cable to the remote positive(+)post
of the vehicle with discharged battery.
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.
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.
Once the engine is started, remove the jumper cables in the reverse sequence:
1. Disconnect the negative(-)end of the jumper cable from the remote negative(-)
post of the vehicle with the discharged battery.
2. Disconnect the opposite end of the negative(-)jumper cable from the negative(-)
post of the booster battery.
3. Disconnect the positive(+)end of the jumper cable from the positive(+)post of
the booster battery.
4. Disconnect the opposite end of the positive(+)jumper cable from the remote
positive(+)post of the discharged vehicle.
5. Reinstall the protective cover over the remote positive(+)post of the vehicle with
the discharged battery.
6. Reinstall the protective plug over the remote negative(-)post of the vehicle with
the discharged battery.
NOTE:
If frequent jump-starting is required to start your vehicle you should have the battery
and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other booster source with a
system voltage greater than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power from
the vehicle’s battery, even when not in use (e.g., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s battery discharges suffi-
ciently to degrade battery life and/or prevent the engine from starting.
