WARNING
■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.
● 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, repair the flat tire by us ing 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.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.

When trouble arises
WARNING
■ 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 low speed. Be especially careful when turn-
ing 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 130 kPa (1.3 kgf/cm2
or bar, 19 psi) or less, the tire may be severely damaged.
NOTICE
■ When performing an emergency repair
● A tire should only be repaired with the emergency tire puncture repair kit if
the damage is caused by a sharp object such as nail or screw passing
through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergenc y repair with the repair kit.
● The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
● Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction may
occur.
● Make sure the sealant bottle of the repair kit is in a vertical position. The
repair kit does not operate properly when it is laid.
■ Precautions for the emergency tire puncture repair kit
● The repair kit power source should be 12 V DC suitable for vehicle use. Do
not connect the repair kit to any other source.
● If fuel splatters on the repair kit, the repair kit may deteriorate. Take care
not to allow fuel to contact it.
● Place the repair kit in a storage to prevent it from being exposed to dirt or
water.
● Store the repair kit in the luggage compartment out of reach of children.
● Do not disassemble or modify the repair kit. Do not subject parts such as
the air pressure indicator to impacts. This may cause a malfunction.
