CRUISE- Cruise Set Indicator
Indicates that the cruise control has been set.
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 transmission into NEUTRAL, but do notincrease engine idle speed.
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.
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.
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
WARNING!
• Do not attempt to change a tire on the side of the vehicle close to movingtraffic. 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.
Jack Location
The jack and lug wrench are located in the rear storage compartment.
NOTE:
Turn the black plastic wing nut counterclockwise to loosen the jack from the storage
bin.

JUMP-STARTING PROCEDURES
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.
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.

WARNING!
•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 rings, watch bands and bracelets that couldmake an inadvertent electrical contact. You could be seriously 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.
1. Set the parking brake, shift the automatic transmission into PARK (manual transmission in NEUTRAL) 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.
WARNING!
Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump-starting procedure 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 vehicle.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper cable to the 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 a good engine ground
(exposed metal part of the discharged vehicle’s engine) away from the battery and
the fuel injection system.
WHAT TO DO IN EMERGENCIES
114

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 serious
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 afew minutes, and then start the engine in the vehicle with the discharged battery.
6. Once the engine is started, remove the jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
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.
If frequent jump starting is required to start your vehicle you should have the battery
and charging system inspected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets draw power from the vehicle’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 discharge suffi-
ciently to degrade battery life and/or prevent the engine from starting.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
NOTE:
For off-road recovery, it is recommended to use both of the front tow hooks to minimize the
risk of damage to the vehicle. Always use an appropriately rated tow strap.
WARNING!
• Do not use a chain for freeing a stuck vehicle. Chains may break, causing serious injury or death.
• Stand clear of vehicles when pulling with tow hooks. Tow straps may become
disengaged, causing serious injury.
