Strength of the driver's and front passenger airbag
The strength with which the driver's and front passenger airbags are triggered depends on the position of the driver's and front passenger seats.
To maintain the accuracy of this function over the long-term, calibrate the front seats when a corresponding message appears on the Control Display.
Calibrating the front seats
A corresponding message appears on the Control Display.
1. Move the respective seat forward all the
way.
2. Move the respective seat forward again. It
moves forward briefly.
3. Readjust the seat to the desired position.
The calibration procedure is completed when the message on the Control Display disappears.
If the message continues to be displayed, repeat the calibration.
If the message does not disappear after a repeat calibration, have the system checked as soon as possible.
Unobstructed area of movement
Ensure that the area of movement of the seats is unobstructed to avoid personal injury or damage to objects.
