When the 12-volt battery charge becomes insufficient or the voltage temporarily drops, the
electric power steering system warning light may come on and the warning buzzer may
sound.

Tire pressure warning light
When a malfunction occurs in the tire pressure warning system, the tire pressure warning
light blinks to warn the driver. However, if the warning light blinks for 1 minute, and then
remains illuminated, making it difficult to determine whether the warning light is blinking,
turn the engine switch <power switch> from off to IGNITION ON mode <ON mode> and
check if the warning light blinks.
When the tire pressure warning light comes on
■
Carry out the following procedure after the tire temperature has lowered sufficiently.
Check the tire inflation pressure and adjust to the appropriate level.

●
If the warning light does not go out even after several minutes, check that the tire inflation
pressure is at the specified level and carry out initialization. (P.352)
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
