Maintenance and care
WARNING
■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.
● 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.
● When replacing the back up light of the right side, be careful not to touch
the exhaust pipes until they have cooled down sufficiently, as touching hot
exhaust pipes can cause burns.
■ 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.

5428-2. Steps to take in an emergency
RAV4-HV_OM_OM42B03U_(U)
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelets. This should only be attempted on hard surfaced roads
for at most short distance at under 18 mph (30 km/h).
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.
Take out the towing eyelet.
Remove the eyelet cover using
a flathead screwdriver.
To protect the bodywork, place a
rag between the screwdriver and
the vehicle body as shown in the
illustration.
Insert the towing eyelet into the
hole and tighten partially by
hand.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing eyelets, cables or chains. The towing eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.
● Do not turn the power switch off.
There is a possibility that the steering wheel is locked and cannot be oper-
ated.
■ 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.
Be sure to transport the vehicle with all
four wheels raised off the ground. If the
vehicle is towed with the tires contacting
the ground, the drivetrain or related parts
may be damaged, the vehicle may fly off
the truck, or electricity generated by the
operation of the motor may cause a fire
to occur depending on the nature of the
damage or malfunction.

straight.
● 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 damage to the vehicle wh en towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
■ To prevent damage to the vehic le during emergency towing

When trouble arises
■Front passenger detection sensor, seat belt reminder and warning
buzzer
● If luggage is placed on the front passenger seat, the front passenger de\
tec-
tion sensor may cause the warning light to flash and the warning buzzer to
sound even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
■ If the malfunction indicator la mp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Toyota dealer
as soon as possible.
■ Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steer ing system warning light may come on
and the warning buzzer may sound.
■
When the tire pressure warning light comes on (vehicles with the tire
pressure warning system)
Check the tire inflation pressure and adjust to the appropriate level. Push-
ing the tire pressure warning reset switch will not turn off the tire pressure
warning light.
■The tire pressure warning light may come on due to natural causes
(vehicles with the tire pressure warning system)
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflat ion pressure changes caused by tem-
perature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (afte r a few minutes).
■When a tire is replaced with a compact spare tire (vehicles with com-
pact spare tire and the tire pressure warning system)
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire ha s been replaced with the spare tire.
Replace the spare tire with the standard tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
