6-3. Do-it-yourself maintenance
CAUTION
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning
off the lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth to avoid
getting 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 headlights or cause condensation to build up on the lens.
●While the headlights are turned on, and for
a short time after they have been turned off,
metal components at the rear of the head-
light assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they have
cooled down.

Maintenance and care
CAUTION
■Discharge headlights
●Contact your Lexus dealer before replacing the discharge headlights (including
light bulbs).
●Do not touch the discharge headlight’s high voltage socket when the headlights
are turned on.
An extremely high voltage of 30000 V will be discharged and could result in
death or serious injury by electric shock.
●Do not attempt to take apart or repair the headlight bulbs, connectors, power
supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installing to prevent heat damage.

7-2. Steps to take in an emergency
If your vehicle needs to be towed
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
●The engine is running but the vehicle will not move.
●The vehicle makes an abnormal sound.
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency
towing eyelet. This should only be
attempted on hard surfaced roads
for short distances at low speeds.
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in good
condition.
If towing is necessary, we recommend having your vehicle towed by
your Lexus dealer or a commercial towing service, using a lift-type
truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
