3287-2. Steps to take in an emergency
■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 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 (vehicles with a com-
pact spare tire)
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
 P. 2 8 6
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-
ing, 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 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
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 inflation pressure immedi-
ately.
●Vehicles with a compact 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 Toyota dealer.
●Vehicles with emergency tire
puncture repair kit: If the tire
pressure warning light comes
on even after tire inflation pres-
sure adjustment, it is probable
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.
●Avoid abrupt maneuvering and
braking.
If the vehicle tires deteriorate,
you could lose control of the
steering wheel or the brakes.

3547-2. Steps to take in an emergency
One of the following may be the
cause of the problem:
There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
 The engine may be flooded.
Try to restart the engine again
following correct starting pro-
cedures. ( P.133)
 There may be a malfunction
in the engine immobilizer sys-
tem. ( P.64)
One of the following may be the
cause of the problem:
 The battery may be dis-
charged. ( P.358)
NOTICE
■Driving with tire chains and
the compact spare tire
Do not fit tire chains to the com-
pact spare tire. Tire chains may
damage the vehicle body and
adversely affect driving perfor-
mance.
■When replacing the tires
When removing or fitting the
wheels, tires or the tire pressure
warning valve and transmitter,
contact your Toyota dealer as the
tire pressure warning valve and
transmitter may be damaged if not
handled correctly.
If the engine will not
star t
If the engine will not start
even though correct starting
procedures are being fol-
lowed ( P.133), consider
each of the following points:

even though the starter
motor operates normally.
The starter motor turns
over slowly, the interior
lights and headlights are
dim, or the horn does not
