IN CASE OF AN EMERGENCY
(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
D 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.
D If you should accidentally get acid on yourself or in your
eyes, remove any contaminated clothing and flush the
affected area with water immediately. Then get immediate
medical attention. If possible, continue to apply water with
a sponge or cloth while en route to the medical office.
D 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.
