If Engine Fails to Start
WARNING!
²Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
²Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Un-
burned fuel could enter the catalytic converter and
once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged 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 Section 6
of this manual for proper jump starting proce-
dures and follow them carefully.
If the engine fails to start after you have followed the
ªNormal Startingº or ªExtreme Cold Weatherº proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, 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.

JUMP STARTING
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, so follow this procedure
carefully.WARNING!
Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don't
lean over battery when attaching clamps or allow the
clamps to touch each other. If acid splashes in eyes or
on skin, flush contaminated area immediately with
large quantities of water.
A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away from
the vent holes.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. Do
not use a 24 volt power source.
300 WHAT TO DO IN EMERGENCIES

1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.
2. Park the booster vehicle within cable reach but with-
out letting the vehicles touch. Set the parking brake on
both vehicles, place the transmission in P (Park), and turn
the ignition OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the engine of the
vehicle with the discharged battery. Make sure you have
a good contact on the engine.
6. Start the engine in the vehicle which has the booster
battery, let the engine idle a few minutes, then start the
engine in the vehicle with the discharged battery.
7. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
WARNING!
²You should not try to start your vehicle by pushing
or towing.
²Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump start.
