5-2. Steps to take in an emergency
●If non-genuine Scion wheels are used. (Even if you use Scion
wheels, the tire pressu
re warning system may not work properly with
some types of tires.)
●If tire chains are used.
●If emergency tire puncture repair kit is used.
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1
minute when the engine switch is turned to the ON position, have it
checked by your Scion dealer.
■ Customization that can be configured at Scion dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 343)
CAUTION
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate 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 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 immediately.
●If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, temporary repair it with liquid sealants and have the
flat tire repaired or replaced by the nearest Scion dealer as soon as
possible.
●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 syste m may not activate immediately.

5-2. Steps to take in an emergency
CAUTION
■When fixing the flat tire
●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 comp leted, the sealant may splatter when
the hose is disconnected or so me air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures 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 ope ration is being performed. If you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
●The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 60 minutes.
●Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the metal part
connecting the bottle and the co mpressor. 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.
■Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
●Drive the vehicle carefully at a lo w speed. Be especially careful when
turning and cornering.
●If the vehicle does not drive straight or you feel a pull through the
steering wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely damaged.

5-2. Steps to take in an emergency
If the engine will not star t
If the engine still does not start after following the correct starting
procedure ( P. 113) or releasing the steering lock (P. 114), confirm
the following points.
■ The engine will not start even when the starter motor oper-
ates normally.
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 once more following correct starting
procedures. ( P. 1 1 3 )
● Vehicles with engine immobilizer system: There may be a
malfunction in the engine immobilizer system.
(  P. 6 2 )
■ The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem.
●The battery may be discharged. ( P. 309)
● The battery terminal connec tions may be loose or corroded.

318 5-2. Steps to take in an emergency
CAUTION
■If the engine has to be turned off while driving
●Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Never attempt to remove the key, as doing so will lock the steering wheel.
