to the ªACCº or ªONº position. It goes off after about 6
seconds. This means the SRS side airbags and curtain
shield airbags are operating properly.

assembly, front airbag sensors, side and curtain shield airbag
sensors, seat belt pretensioner assemblies, inflators, warning
light, interconnecting wiring and power sources. (For details,
see ªService reminder indicators and warning buzzersº on
page 48.)
If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact

NOTICE
Do not put magnets or a metal object near the inside rearview mirror. Doing this may cause malfunction of thecompass sensor.
CALIBRATING THE COMPASS (deviation calibration)
The direction display on the compass deviates from the true
direction determined by the earth's magnetic field. The amount
of deviation varies according to the geographic position of the
vehicle.
To adjust for this deviation, stop the vehicle and push the
button for longer than about 6 seconds until the number (1±15)
appears on the display. Then push the button again, referring
to the following map to select the number of the zone where the
vehicle is.

Zone number
If the direction is displayed several seconds after adjustment,
the calibration is finished.

STARTING AND DRIVING
262
You may hear the anti±lock brake system operating and feel
the brake pedal pulsating and the vibrations of the vehicle
body and steering wheel. You may also hear the motor
sound in the engine compartment even after the vehicle is stopped.
 At the end of the anti±lock brake system activation, the
brake pedal may move a little forward.
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.
