After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (P. 534)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.

Condensation build-up on the inside of the lens
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional for more information in the following situations.
Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction.

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. 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.
To prevent damage or fire
Make sure bulbs are fully seated and locked.

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 eyelets 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 an accident as the front wheels will be locked by the
parking lock.
If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
NOTICE
To prevent damaging the vehicle
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the vehi-
cle could be damaged while being towed.
To prevent causing serious damage to the hybrid 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 body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
To prevent causing serious damage to the hybrid transmission in emergency
towing
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the hybrid transmission.
