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 wh eels raised or
with all four wheels raised off the
ground. If the vehicle is towed
with the front wh eels 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 t owing 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.

3647-2. Steps to take in an emergency
system warning light may come on
and the warning buzzer may sound.
■When the tire pressure warning
light comes on (vehicles with a
tire pressure warning system)
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.370
If none of the tires are punctured:
Turn the engine switch off then turn
it to ON. Check if the tire pressure
warning light comes on or blinks.
If the tire pressure warning light
blinks for approximately 1 minute
then stays on
There may be a malfunction in the
tire pressure warning system. Have
the vehicle inspected by your Toyota
dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation pressure of each tire
and adjust them to the specified
level.
2 If the warning light does not turn
off even after several minutes
have elapsed, check that the
inflation pressure of each tire is
at the specified level and perform
initialization. ( P.318)
■The tire pressure warning light
may come on due to natural
causes (vehicles with a tire
pressure warning system)
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a
spare tire (vehicl es with a tire
pressure warning system)
The compact spare tire is not
equipped with a tire pressure warn-
ing valve and transmitter. If a tire goes flat, the tire pressure warning
light will not turn off even though the
flat tire has been replaced with the
spare tire. Replace the spare tire
with the repaired tire and adjust the
tire inflation pressure. The tire pres-
sure warning light will go off after a
few minutes.
■Conditions that the tire pres-
sure warning system may not
function properly (vehicles with
a tire pressure warning system)

WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer.
The vehicle will become
extremely unstable during brak-

which could cause an accident
resulting in death o r serious injury.
■When the electric power
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assis t to the power
steering is lost and handling oper-
ations of the steering wheel
become extremely heavy.
When steering wheel operations
are heavier than usual, grip the
steering wheel firmly and operate
it using more fo rce than usual.
■If the tire pressure warning
light comes on ( vehicles with
a tire pressure warning sys-
tem)
Be sure to observe the following
precautions.
Failure to do so could cause a
loss of vehicle control and result
in death or serious injury.
