IN CASE OF AN EMERGENCY
131 If the engine still will not start, it needs adjustment or repair. Call
a Lexus dealer. Roadside Assistance or Customer Service
Assistance. (See “Foreword”.)
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 how 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 en
route to the medical office.
The gas normally produced by a battery will explode if
a flame or spark is brought near. Use only standardized
jumper cables and do not smoke or light a match while
jump starting.
NOTICE:
The battery used for boosting must be 12 V. Do not jump
start unless you are sure that the booster battery is
correct.

IN CASE OF AN EMERGENCY
132JUMP 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 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 terminal (“+” mark)−to−positive terminal
(“+” mark), and negative terminal (“−” 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, 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 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.
