Jump Starting
If the battery is discharged, the engine
should be started with jumper cables
and the (12 V) battery of another
vehicle.
The battery is located in the trunk
behind the right-hand cover panel.
Warning!
Failure to follow these directions will
cause damage to the electronic
components, and can lead to a
battery explosion and personal
injury.
Read all instructions before
proceeding.
Proceed as follows:
1. Position the vehicle with the
charged battery so that the
jumper cables will reach, but
never let the vehicles touch.
Make sure the jumper cables
do not have loose or missing
insulation.
2. On both vehicles:
• Turn off engine and all lights and
accessories, except hazard
warning flashers or work lights.
• Apply parking brake and shift
selector lever to position "P".
Important!
3, Clamp one end of the first
jumper cable to the positive
(+) terminal of the discharged
battery and the other end to the
positive (+) terminal of the charged
battery. Make sure the cable
clamps do not touch any other
metal parts.
4. Clamp one end of the second
jumper cable to the grounded
negative (-) terminal of the
charged battery and the final
connection to the negative (-)
terminal of the discharged
battery. Make sure the cables
are not on or near pulleys, fans,
or other parts that will move
when the engine is started.
