CAUTION
Discharge headlights (if equipped)
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional before replacing the discharge headlights
(including light bulbs).
Do not touch the discharge headlight’s high voltage socket when the head-
lights 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.
NOTICE
When replacing the outer foot lights
If the front window is stopping you from conducting the replace operation
properly, open the window on the side you are working on to allow you
enough space to work. Continuing the operation without giving yourself
enough space to work could lead you to scratch the vehicle.

NOTICE
To prevent causing serious damage to the transmission when towing using a
wheel-lift type truck
Never tow this vehicle from the front with the rear wheels on the ground.
To prevent damage to the vehicle when towing using a wheel-lift type truck
Do not tow the vehicle from the rear with the power switch off. The steer-
ing lock mechanism is not strong enough to hold the front wheels straight.
When raising the vehicle from the rear, ensure adequate ground clearance
for towing at the opposite end of the raised vehicle. Without adequate
clearance, the vehicle could be damaged while being towed from the rear.
To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
