WARNING

■

Battery precautions

Observe the following precautions.

Failure to do so may result in death or serious injury.

●

Do not swallow the battery. Doing so may cause chemical burns.

●

A coin battery or button battery is used in the electronic key. If a battery is swallowed,

it may cause severe chemical burns in as little as 2 hours and may result in death or

serious injury.

●

Keep away new and removed batteries from children.

●

If the cover cannot be firmly closed, stop using the electronic key and stow the key in

the place where children cannot reach, and then contact your Lexus dealer.

●

If you accidentally swallow a battery or put a battery into a part of your body, get

emergency medical attention immediately.

■

To prevent battery explosion or leakage of flammable liquid or gas

●

Replace the battery with a new battery of the same type. If a wrong type of battery is

used, it may explode.

●

Do not expose batteries to extremely low pressure due to high altitude or extremely

high temperatures.

●

Do not burn, break or cut a battery.

NOTICE

■

For normal operation after replacing the battery

Observe the following precautions to prevent accidents:

●

Always work with dry hands.

Moisture may cause the battery to rust.

●

Fully install light bulbs and any parts used to secure them. Failure to do so may result

in heat damage, fire, or water entering the headlight unit. This may damage the head-

lights or cause condensation to build up on the lens.

●

Do not attempt to repair or disassemble light bulbs, connectors, electric circuits or

component parts.

Doing so may result in death or serious injury due to electric shock.

■

To prevent damage or fire
