IN CASE OF AN EMERGENCY
125
NOTICE:
Do not crank for more than 15 seconds at a time. This
may overheat the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and damage to your
vehicle which might result from battery explosion, acid
burns, electrical burns, or damaged electronic
components, these instructions must be followed
precisely.
If you are unsure about hove to follow this procedure, we
strongly recommend that you seek help from your Lexus
dealer, Roadside Assistance or Customer Service Assistance.
(See “Foreword”.)
CAUTION:
Batteries contain sulfuric acid which is poisonous and
corrosive. Wear protective safety glasses when jump
starting, and avoid spilling acid on your skin, clothing,
or vehicle. If you should accidentally get acid on
yourself or in your eyes, remove any contaminated
clothing and flush the affected area with water for at
least 15 minutes. Then get immediate medical
attention. If possible, continue to apply water with a
sponge or cloth while traveling to the medical office.
The gas normally produced by a battery will explode if
a flame or spark is brought near. Therefore, do not
smoke or light a match while jump starting.
NOTICE:
The battery used for boosting must be 12-volt. Do not
jump start unless you are sure that the booster battery
is the correct voltage.

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.
IN CASE OF AN EMERGENCY
1262. 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.)
If the booster battery is an extended maintenance interval
battery, it is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for a few 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-to-positive (+), and negative-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, metallic point (e.g. engine hanging hook)
away from the battery. Do not connect it to or near any part that
moves when the engine is cranked
NOTICE:
When making the connections, do not lean over the
battery or accidentally let the jumper cables or clamps
touch anything except the correct battery terminals or
the ground.
5. Start your engine in the normal way. After starting, run it at
about 2000 rpm for several minutes with the accelerator pedal
lightly depressed6. Carefully disconnect the cables in the exact reverse order:
the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloth which may now
contain sulfuric acid.
8. 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 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.
You should follow this procedure ...
1. Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in “P” (automatic) or
neutral (manual) and apply the parking brake. Turn off the air
conditioner if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir,
stop the engine. Wait until the steam subsides before opening
the hood. If there is no coolant boiling over or steam, leave the
engine running and make sure that the engine cooling fan is
operating. If it is riot, turn the ignition off.
CAUTION:
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is a sign of
very high pressure.
