JUMP STARTING VEHICLES
To Jump Start Your Vehicle
WARNING!
When jump starting using a battery
booster, it is best to jump start with
an equivalently powered vehicle.
Verify that the booster battery has
the same volt and CCA specifica-
tions as the dead battery before
attempting to jump start.
Failure
to comply may cause an explosion
resulting in death, personal injury,
equipment or property damage.
CAUTION
Applying a higher voltage booster
battery may cause expensive dam-
age to sensitive electronic compo-
nents, such as relays, Electronic
Control units or electronics in gen-
eral. Failure to comply may result in
equipment damage.
CAUTION
Improper hook-up of jumper cables
or not following these procedures
can damage the alternator or cause
serious damage to both vehicles.
WARNING!
Heed all warnings and instructions
of the jumper cable manufacturer.
Failure to comply may result in
death, personal injury, equipment or
property damage.
Preparing the vehicles:
1. Remove any personal jewelry
that may come in contact with the
battery terminals.
2. Select a jumper cable that is long
enough to attach to both vehicles
in a way that ensures neither
vehicle touches each other.
3. Position the two vehicles together,
but do not allow them to touch.
4. Turn OFF all lights, heater, radio,
and any other accessory on both
vehicles.
5. Set the parking brakes: pull out
the Yellow button located on the
dash.
6. Shift the transmission into park
position or neutral for manual
transmissions. (See Operating
the Transmission on page 4-22
and Parking Brake Valve on page
4-43, for transmission shifting and
parking brake information.)
