GAUGES, METERS AND SERVICE REMINDER INDICATORS
58Any of the following conditions may occur, but do not
indicate the malfunction:
The light may stay on for about 60 seconds after the ignition
key is turned to the ONº position. It is normal if it turns off
after a while.
Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Driver's Seat Belt Reminder Light and Buzzer
This light and buzzer remind you to buckle up the driver's seat
belt.
Once the ignition key is turned to ONº or STARTº, the
reminder light flashes and buzzer sounds if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
stays flashing and the buzzer stops after about 4 to 8 seconds.
(c) Front Passenger's Seat Belt Reminder Light
This light reminds you to buckle up the front passenger's seat
belt.
Once the ignition key is turned to ONº or STARTº, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light stays flashing.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built-in sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.

STARTING AND DRIVING
400
CAUTION
Do not overestimate the anti-lock brake system:
Although the anti-lock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the anti-lock
brake system on.
If tire grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the anti-lock brake system does not provide
vehicle control.
Anti-lock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti-lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snow-covered roads.
Driving with tire chains installed.
Driving over the steps such as the joints on the road.
Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti-lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.
