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.

■

To prevent damage or fire

Make sure bulbs are fully seated 

and locked.

7-2.Steps to take in an emergency

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.

WARNING

Observe the following precau-

tions.

Failure to do so may result in 

death or serious injury.

■

When towing the vehicle

Be sure to transport the vehicle 

with the front wheels raised or 

with all four wheels raised off the 

ground. If the vehicle is towed 

with the front wheels contacting 

the ground, the drivetrain and 

related parts may be damaged.

■

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.

NOTICE

■

To prevent damage to the 

vehicle when towing using a 

wheel-lift type truck

●

Vehicles without a smart key 

system: Do not tow the vehicle 

from the rear when the engine 

switch is off or the key is 

removed. The steering lock 

mechanism is not strong 

enough to hold the front wheels 

straight.

●

Vehicles with a smart key sys-

tem: Do not tow the vehicle from 

the rear when the engine switch 

is off.

●

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.

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 
50 miles (80 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 a continuously 
variable transmission, only the 
front towing 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 and towing eyelet.
