The tire pressure warning light may come on due to natural causes

The tire pressure warning light may come on due to natural causes such as
natural air leaks or tire inflation pressure changes caused by temperature. 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 (if equipped)

Vehicles with full-size  spare  tire: The spare tire  is also  equipped  with  a tire
pressure  warning  valve  and  transmitter. The  tire  pressure  warning  light  will
turn on if the tire inflation pressure of the spare tire is low. 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 pressure warning light will go off
after a few minutes.
Vehicles with compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and transmitter. If a tire goes flat, the tire pres-
sure 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 pressure warning  light will  go off  after a  few
minutes.

7-2. Steps to take in an emergency

WARNING

■

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. The
vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or 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 assist to the power steering is
lost  and  handling  operations  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 force than usual.

■

If the tire pressure warning light comes on

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.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.

●

Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that you have a flat
tire. Check the tires. If a tire is flat, change it with the spare tire and have
the flat tire repaired by the nearest any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.

●

Vehicles with emergency tire puncture repair kit: If the tire pressure warn-
ing light comes on even after tire inflation pressure adjustment, it is proba-
ble that you have a flat tire. Check the tires. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit. (



P. 697)

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.

■

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

If you have a flat tire (vehicles with an

emergency tire puncture repair kit)

Vehicles equipped with an emergency tire puncture repair kit do
not have a spare tire equipped.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily with the emergency tire punc-
ture repair kit.

WARNING

■

If you have 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, which could result in an accident.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.

698

7-2. Steps to take in an emergency

●

Stop the vehicle in a safe place on a hard, flat surface.

●

Set the parking brake.

●

Shift the shift lever to P.

●

Stop the hybrid system.

●

Turn on the emergency flashers.

●

Check the degree of the tire damage.

A  tire  should  only  be  repaired
with  the  emergency  tire  punc-
ture  repair  kit  if  the  damage  is
caused by a nail or screw pass-
ing through the tire tread.

• Do not remove the nail or

screw  from  the  tire.  Remov-
ing the object may widen the
opening  and  make  emer-
gency  repair  with  the  repair
kit impossible.

• To avoid sealant leakage, move the vehicle until the area of the

puncture, if known, is positioned at the top of the tire.
