starter will disengage automatically in 10 seconds. If this
occurs, turn the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.
Extreme Cold Weather (Below –20°F Or 29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the crank cycle.
2. Place the ignition in the START position and release it when the engine starts. 3. If the engine fails to start within 10 seconds, place the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after 8 attempts, allow the starter to cool for at least 10 minutes, then repeat the
procedure.
If Engine Fails To Start
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.

STARTING AND OPERATING 421

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission 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” in “What To Do In Emergen-
cies” for further information.
With Tip Start
If the engine fails to start after you have followed the
Normal Starting, “Extreme Cold Weather andEx-
tended Park Starting procedures, it may be flooded. To clear any excess fuel, press the accelerator pedal all the
way to the floor and hold it. Then, cycle the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will disengage auto-
matically in 10 seconds. Once this occurs, release the
accelerator pedal, cycle the ignition to the LOCK posi-
tion, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 seconds
before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.

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!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
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 is covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post.
578 WHAT TO DO IN EMERGENCIES

3. If using another vehicle to jump-start the battery, parkthe 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.
580 WHAT TO DO IN EMERGENCIES

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 boosterbattery, let the engine idle a few 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 dis-
charged 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 in-
spected 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 phones, etc.). Eventually, if
plugged in long enough without engine operation,
