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 immedi-
ately 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.
1. Remove all metal jewelry such as watch bands or
bracelets which might make an unintended electrical
contact.
346 WHAT TO DO IN EMERGENCIES

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.
348 WHAT TO DO IN EMERGENCIES

WARNING!
•You should not try to start your vehicle by push-
ing or towing.
•Do not connect the cable to the negative post of
the discharge battery. The resulting electrical
spark could cause the battery to explode.
•During 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.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, there will be
one in the rear and two mounted on the front of the
vehicle. The rear hook will be located on the driver’s side
of the vehicle.
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.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
