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
Jack Location
• The jack and lug wrench are located in the rear storage compartment.
NOTE:
Turn the black plastic wing nut counter clockwise to loosen the jack from the storage
bin.
Spare Tire Stowage
•To remove the spare tire from the car-
rier, remove the tire cover, if equipped,
and remove the lug nuts with the lug
wrench turning them counterclockwise.
NOTE:
If you have added aftermarket accesso-
ries to the spare tire mounted carrier, it
cannot exceed a gross weight of 85 lbs
(38.5 kg) including the weight of the
spare tire.
Preparations For Jacking
1. Park on a firm, level surface. Avoid ice
or slippery areas.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Shift the automatic transmission into PARK, or a manual transmission into

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.
• Carefully follow these tire changing warnings to help prevent personal injury or
damage to your vehicle:
• 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;
a manual transmission in REVERSE.
• 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.
• Raising the vehicle higher than necessary can make the vehicle less
stable and cause a collision. 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.
• A loose tire or jack, thrown forward in a collision or hard stop, could en-
danger the occupants of the vehicle. Always stow the jack parts and the
spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the lug
nuts fully until the vehicle is lowered to the ground.

JUMP-STARTING
• If your vehicle has a discharged bat-
tery it can be jump-started using a set
of jumper cables and a battery in an-
other 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 in
the right rear of the engine compartment.
1. Set the parking brake, shift the automatic transmission into PARK and turn the
ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. If using another vehicle to jump-start the battery, park the vehicle within the
jumper cables reach, set the parking brake and make sure the ignition is OFF.
Jump-Starting Procedure
1. Connect the positive(+)end of the jumper cable to the positive(+)post of the
vehicle with the 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 a good engine ground
(exposed metal part of the discharged vehicle’s engine) away from the battery and
the fuel injection system.
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 engine ground 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 positive(+)
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.
WARNING!
• When temperatures are below the freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting because the battery could
rupture or explode and cause personal injury. Battery temperature must be
brought above the freezing point before attempting a jump-start.
•Take care to avoid the radiator cooling fan whenever the hood is raised. It can start
anytime the ignition switch is on. You can be injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make
an inadvertent electrical contact. You could be severely injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate
hydrogen gas which is flammable and explosive. Keep open flames or sparks
away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property
damage due to battery explosion.
• Do not connect the 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.
