IN CASE OF AN EMERGENCY
279
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make
sure the vehicles are not touching. Turn off all unnecessary
lights and accessories.
2. If required, remove all the vent plugs from the booster
battery.
Lay a cloth over the open vents on the booster battery.
(This helps reduce the explosion hazard, personal injuries and
burns.)
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for about 5 minutes. During
jump starting, run the engine at about 2000 rpm with the
accelerator pedal lightly depressed.
4. Connect the jumper cables in the exact order shown in the
illustration: positive terminal (º+º mark)±to±positive
terminal (º+º mark), and negative terminal (º±º
mark)±to±engine or body ground. Note that you first connect
the positive cable to the discharged battery and then to the
booster battery. Next, connect the negative cable to the
booster battery and then to a solid, stationary, unpainted
metallic point (e.g. SC400: brake booster vacuum pipe
bracket, SC300: cylin der head) away from the battery. Do not
connect it to or near any part that moves when the engine is
cranked.
CAUTION
When making the connections, to avoid serious injury, do not
lean over the battery or accidentally let the jumper cables or
clamps touch anything except the correct battery terminals or
the ground.

IN CASE OF AN EMERGENCY
2805. Start your engine in the normal way. After starting, run it
at about 2000 rpm for several minutes with the accelerator
pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may
now contain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for
example, lights left on), you should have it checked.
IF YOUR VEHICLE
OVERHEATS
If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if you
hear a loud knocking or pinging noise, the engine has
probably overheated.
