CONTROLS AND INSTRUMENTS
NOTE
[These are not signs of ABS malfunction]
• Immediately after the engine is started, a motor sound may be heard from the
rear of the vehicle or from the underside of the cab. This sound is from a self-
check by the ABS. In addition, you may also feel some vibration if the brake
pedal is pressed at this time.
• When ABS is operating, vibration is felt on the brake pedal and steering wheel
and you may hear the system operating. This is normal when ABS is properly
operating.
• When ABS is activated while the exhaust brake is in operation, the exhaust
brake may release.
• ABS is more likely to be activated when the brake is applied during cornering or
driving over a bump. This is because inside wheels or wheels that have gone
over a bump tend to lock.
• ABS is not activated immediately after starting the vehicle. It is activated only
when the vehicle speed reaches approx. 10 km/h (6 MPH). ABS operation is
inactive when the vehicle speed reduces to approx. 5 km/h (3 MPH).
