If the battery is discharged, the engine
should be started with jumper cables
and the (12V) battery of another
vehicle.
The battery is located in the trunk
behind the right-hand cover panel.
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.
Important!
5. Start engine of the vehicle with
the charged battery and run at
high idle. Make sure the cables
are not on or near pulleys, fans,
or other parts that will move
when the engine is started.
Then start engine of the
disabled vehicle in the usual
manner.
5. After the engine has started, remove
jumper cables by exactly reversing
the above installation sequence,
starting with the last connection
made first. When removing each
clamp, make sure that it does not
touch any other metal while the
other end is still attached.
Important!
A discharged battery can freeze at
approx. +14°F (-10°C). In that case, it
must be thawed out before jumper
cables are used. A frozen battery can
explode and cause personal injury.
Jumper cable specifications:
• Minimum cable cross-section of
25 mm
2
or approx. 2 AWG
• Maximum length of 11.5 ft.
(3.5 m).
