emergencies. To jump start, use another 24 volt
DC, negative grounded, power source. Use only
jumper cables rated at 500 cranking amperes.
DANGER
Injury, explosion, battery acid damage or
charging system overload may result if these
jump starting procedures are not precisely
followed.
WARNING
Wear eye protection and remove rings, metal
jewelry and watches with metal bands.
DANGER
The battery could rupture or explode if jump
started when the run- down battery fluid is
frozen or if the battery fluid level is low. Check
condition of run-down battery before attempting
to jump start.
DANGER
The gases given off by batteries while jump
starting are explosive. Do not smoke near
batteries.
CAUTION
Do not let the two vehicles touch. Keep a walk-
through distance between the two vehicles.
Make sure positive (red) and negative (black)
jumper cable clamps do not touch.
CAUTION
Never connect the jumper cable to the negative
terminal post of the run-down battery.
CAUTION
Do not jump start if a maintenance-free battery
has a yellow test indicator. Have the battery
replaced.
Starting and Stopping Procedures 6-5
Before attempting to jump start, make sure the
parking brake is applied and the transmission is in
neutral (N). Turn off all lights, heaters and other
electrical accessories.
Choose a booster vehicle which produces
comparable amperage as your vehicle.
Off- board battery charger with a start boost
facility must not be used to jump start the
vehicle. This could damage the electrical
system.
FIGURE 4: BOOSTER BLOCK TERMINALS LOCATION
