Emergency situations

Jump starting

Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, have a service technician or
towing service do it for you.
WARNING
To prevent SERIOUS INJURY or DEATH to
you or bystanders, always follow these
precautions when working near or
handling the battery:
Always read and follow instructions
carefully when handling a battery.
Wear eye protection designed to protect
the eyes from acid splashes.
Keep all flames, sparks, or smoking
materials away from the battery.
Hydrogen is always present in battery
cells, is highly combustible, and may
explode if ignited.
Keep batteries out of reach of children.
Batteries contain sulfuric acid that is
highly corrosive. Do not allow acid to
contact your eyes, skin, or clothing.
8-4
If acid gets into your eyes, flush your eyes
with clean water for at least 15 minutes
and get immediate medical attention. If
acid gets on your skin, thoroughly wash
the area. If you feel pain or a burning
sensation, get medical attention
immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the battery
when the vehicle's battery cables are
connected to the battery.
• The electrical ignition system works
with high voltage.
NEVER touch these components with
the engine running or when the ignition
switch is in the ON position.
Jump starting procedure
1. Position the vehicles close enough that
the jumper cables can reach. Do not
allow the vehicles to touch.
2. Avoid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such as
radios, lights, air conditioning, etc. Put
the vehicles in P (Park) and apply the
parking brake. Turn both vehicles OFF.
4. Open the engine hood.
CAUTION
Before jump starting, make sure to
correctly identify the positive (+) and
negative (-) terminals to avoid reverse
polarity connections.
