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. Hold the
bulb by the plastic or metal portion.
If the bulb is scratched or dropped it may blow out or crack.
Fully install light bulbs and any parts used to secure them. Failing 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.
Discharge headlights (if equipped)
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional, before replacing discharge headlights (includ-
ing light bulbs).
Do not touch the high-intensity discharge headlight’s high voltage socket
when the headlights are turned on.
An extremely high voltage of 20000 V will be discharged and could result
in serious injury or death by electric shock.
Do not attempt to take apart or repair the low beam discharge headlight
bulbs, connectors, power supply circuits, or related components.
Doing so could result in electric shock and serious injury or death.
To prevent damage or fire
Make sure bulbs are fully seated and locked.

vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.

CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelet and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
Do not turn the “POWER” switch off.
This may lead to accidents as the parking lock will be engaged.
If the hybrid system is not operating, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
Installing towing eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing. This
may lead to accidents that cause death or serious injury.
NOTICE
To prevent causing serious damage to the transmission
Never tow the vehicle from the rear with the front wheels on the ground.
This may cause serious damage to the transmission.
To prevent damaging the vehicle when towing using a wheel-lift type
truck
When raising the vehicle, 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.
To prevent body damage when towing using a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
