Wheel Alignment Values
WARNING:
Steering-angle sensor not calibrated or calibrated incorrectly
- Unexpected vehicle handling
- Steering-angle sensor does not function
- Malfunction in steering-angle sensor
→ After working on wheel suspension parts, when replacing the steering-angle sensor and after changing the wheel alignment values, calibrate the steering-angle sensor using PIWIS Tester II 9818 .
→ Keep the front wheels in straight-ahead position on the measuring platform during calibration.
→ On vehicles with electromechanical steering, also re-teach the electric steering lock settings.
Information
- The values also apply from model year 2009 onwards.
- The following values relate to the empty weight, i.e. full fuel tank, vehicle with tools but without driver or additional weights .
- The toe-difference angle value is also influenced by the vehicle height. For this reason the measured result must be evaluated accordingly. No action is necessary in the case of small deviations from the toe-difference angle's required value as long as the value to the right and left is almost the same .
