moisture and oils on the bulb.

Also, if the bulb is scratched or dropped, it may blow out or crack.

●

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

●

Make sure bulbs are fully seated and locked.

If the vehicle is submerged or water on the road is
rising

●

If the door can be opened, open the door and exit the vehicle.

●

If the door can not be opened, open the window using the power window
switch and ensure an escape route.

●

If the window can be opened, exit the vehicle through the window.

●

If the door and window cannot be opened due to the rising water, remain
calm, wait until the water level inside the vehicle rises to the point that the
water pressure inside of the vehicle equals the water pressure outside of the
vehicle and then open the door after waiting for the rising water to enter the
vehicle, and exit the vehicle. When the outside water level exceeds half the
height of the door, the door cannot be opened from the inside due to water
pressure.

■

Water level exceeds the floor

When the water level exceeds the floor and time has passed, the electrical equipment

will get damaged, the power windows will not operate, the engine stop, and the vehicle

may not be able to get moving.
