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. Fail-
ure to do so may result in heat
damage, fire, or water entering
the light unit. This may damage
the lights or cause condensa-
tion to build up on the lens.
■When changing the back-up
lights
●Stop the engine and wait until
the exhaust pi pes and sur-
rounding parts have cooled
down sufficiently. The lights are
located near the exhaust pipe
and touching a hot exhaust pipe
and surrounding parts 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.

If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
If towing your vehicle with a
wheel-lift type truck from
the front, the vehicle's rear
wheels and axles must be in
good conditions. ( P.342)
If they are damaged, use a
towing dolly or flatbed
truck.
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When towing the vehicle
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain and related
parts may be damaged or an acci-
dent may occur due to a change
in direction of 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 eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not turn the engine switch
off.
There is a possibility that the
steering wheel is locked and
cannot be operated.
■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.

3427-2. Steps to take in an emergency
The following may indicate a
problem with your transmission.
Contact your Toyota dealer or
commercial towing service
before towing.
The engine is running but the
vehicle does not move.
 The vehicle makes an abnor-
mal sound.
From the front
Use a towing dolly under the
rear wheels.
From the rear
WARNING
■After towing
Make sure to remove the towing
eyelet.
If not removed, the SRS airbags
may not deploy correctly if the
vehicle is involved in a frontal col-
lision, or the fuel pump shutoff
system may not operate correctly
if involved in a rear collision.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
●Do not tow the vehicle from the
rear when the engine switch is
off. The steering lock mecha-
nism is not strong enough to
hold the front wheels straight.
●When raising the vehicle,
ensure adequate ground clear-
ance for towing at the opposite
end of the raised vehicle. With-
out adequate clearance, the
vehicle could be damaged while
being towed.
■To prevent damage to the
vehicle when 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
vehicle during emergency
towing
Do not secure cables or chains to
the suspension components.
■When towing down a long
slope
Use a wheel lift-type or flat bed
truck.
If a wheel lift-type or flat bed truck
is not used, the brakes may over-
heat, leading to poor brake perfor-
mance.

essary to contact dealers

When trouble arises
Use a towing dolly under the
front wheels.
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the engine switch off.
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
19 miles (30 km) 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.
For vehicles with an automatic
transmission, only the front tow-
ing eyelets may be used.
To have your vehicle towed by
another vehicle, the towing eye-
let must be installed to your
vehicle. Install the towing eyelet
using the following procedure.
1
Take out the wheel nut
wrench, flathead screwdriver
and towing eyelet. ( P.359)
2 Remove the eyelet cover
using a flathead screwdriver.
To protect the b odywork, place a
rag between the screwdriver and
the vehicle body as shown in the

When trouble arises
acceleration and sharp turns,
drive carefully at under 50
mph (80 km/h) to the nearest
Toyota dealer that is less
than 124 miles (200 km)
away for tire repair or
replacement.
■After a tire is repaired with the
emergency tire puncture repair
kit
●The tire pressure warning valve
and transmitter should be
replaced.
●Even if the tire inflation pressure is
at the recommended level, the tire
pressure warning light may come
on/flash.
WARNING
■Do not drive the vehicle with
a flat tire
Do not continue driving with a flat
tire.
Driving even a short distance with
a flat tire can damage the tire and
the wheel beyond repair. Driving
with a flat tire may cause a cir-
cumferential groove on the side
wall. In such a case, the tire may
explode when using a repair kit.
■When fixing the flat tire
●Stop your vehicle in a safe and
flat area.
●Do not touch the wheels or the
area around the brakes immedi-
ately after the vehicle has been
driven.
After the vehicle has been
driven, the wheels and the area
around the brakes may be
extremely hot. Touching these
areas with hands , feet or other
body parts may result in burns.
●Connect the valve and hose
securely with the tire installed
on the vehicle.
●If the hose is not properly con-
nected to the valve, air leakage
may occur or sealant may be
sprayed out.
●If the hose comes off the valve
while inflating the tire, there is a
risk that the hose will move
abruptly due to air pressure.
●After inflation of the tire has
completed, the sealant may
splatter when the hose is dis-
connected or some air is let out
of the tire.
●Follow the operation procedure
to repair the tire. If the proce-
dure is not followed, the sealant
may spray out.
●Keep back from the tire while it
is being repaired, as there is a
chance of it bursting while the
repair operation is being per-
formed. If you notice any cracks
or deformation of the tire, turn
off the compressor switch and
stop the repair operation imme-
diately.
●The kit may overheat if operated
for a long period of time. Do not
operate the compressor contin-
uously for more than 10 min-
utes.
●Parts of the kit become hot
during operation. Be careful
handling the kit during and after
operation. Do not touch the
metal part around the connect-
ing area between the bottle and
compressor. It will be extremely
hot.
●Do not attach the vehicle speed
warning sticker to an area other
than the one indicated. If the
sticker is attached to an area
where an SRS airbag is located,
such as the pad of the steering
wheel, it may prevent the SRS
airbag from operating properly.
