Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
Driving on roads with tight curves.
Driving under bad weather conditions (rain, fog, and snow).
The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver's lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes
and other manoeuvres. Always pay attention to the direction in which the vehicle is
travelling and the vehicle's surroundings.
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.
NOTE
If your vehicle deviates from its traf c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the centre of the
lane.
When the direction indicator lever is operated for a lane change, the LDWS warning
is automatically cancelled. The LDWS warning becomes operable when the direction
indicator lever is returned and the system detects the white or yellow lines.
If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically cancelled.
The LDWS may not operate during the period immediately after the vehicle has
deviated from its lane and the LDWS has operated, or the vehicle deviates from its
lane repeatedly within a short period of time.
The LDWS does not operate if it does not detect the white or yellow lines of the traf c
lane.
