250 STARTING AND OPERATING
accelerator pedal and the brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the floor. Release
the accelerator pedal and the ignition button/key once the
engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held to
the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Cold Weather Operation (Below –22°F Or −30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
WARNING!
• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the
vehicle. This could result in flash fire causing serious
personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmis -
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.
• If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or
the battery in another vehicle. This type of start can be
dangerous if done improperly. Refer to “Jump Starting
Procedure” in “In Case Of Emergency” for further
information.
CAUTION!
To prevent damage to the starter, do not crank the engine
for more than 10 seconds at a time. Wait 10 to 15 seconds
before trying again.
398 IN CASE OF EMERGENCY
Lug Wrench Insertion Location — Wheel Cover
Replace the wheel covers using a rubber mallet to ease the
installation. Align the wheel cover vent holes to the wheel
vent holes. Tap on the wheel cover as needed to firmly seat it
evenly around the wheel.
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.
CAUTION!
• Use a pulling motion to remove the hub cap. Do not use a twisting motion when removing the hub cap, damage
to the hub cap; finish may occur.
• The rear hub caps on the dual rear wheel has two pull off notches. Make sure that the hook of the jack handle
driver is located squarely in the cap notch before
attempting to pull off.
WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
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.
IN CASE OF EMERGENCY 399
Preparations For Jump Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:
The positive battery post may be covered with a protective
cap if equipped. Lift up on the cap to gain access to the posi-
tive battery post. Do not jump off fuses. Only jump directly
off positive post which has a positive (+) symbol on or
around the post.
Positive Battery Post 1. Apply the parking brake, shift the automatic transmis-
sion into PARK (P) and turn the ignition OFF.
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, apply the
parking brake and make sure the ignition is OFF.
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 could make 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.

400 IN CASE OF EMERGENCY
Jump Starting Procedure
Connecting The Jumper Cables
1. Connect the positive (+) end of the jumper cable to the
positive (+) post of the discharged vehicle.
NOTE:
Do not jump off fuses. Only jump directly off positive
post. 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.
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury could
result.
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.
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.
CAUTION!
Do not connect jumper cable to any of the fuses on the
positive battery terminal. The resulting electrical current
will blow the fuse.
IN CASE OF EMERGENCY 401
6. Once the engine is started, remove the jumper cables inthe 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 an
authorized dealer.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten -
tial for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase the engine idle speed while
preventing vehicle motion with the brakes.
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. 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 sufficiently to degrade battery life and/or
prevent the engine from starting.
