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
2. will reach, but never let the vehicles
touch. Make sure the jumper cables
do not have loose or missing
insulation.
3. 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.
6. 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
2
25 mm or approx. 2 AWG
• Maximum length of 11.5 ft.
(3.5 m).
