Switching off the TCS
When testing on a roller bench or when towing with an
axle raised, the TCS must be switched off.
Use the display to switch off the TCS. The vehicle
must be stationary.
1 Step to the "Settings" menu (3 and 4)
2 Press "Select" (2)
3 Step to the "Traction Control" menu (3 and 4)
4 Press "Select" (2)
5 Step to the "Off" menu (3 and 4)
6 Press "Select" (2)
The next time the starter key is turned to the driving
position or the front axle is rotating faster than
12 km/h the TCS is engaged again.
If TCS is activated after a wheel change
If you fit smaller wheels on the drive axle than what
was fitted previously, the TCS may be activated.
Drive a distance at above 25 km/h. The EBS system
then learns the difference between the wheel sizes.
How far you need to drive depends on how big the
difference in sizes is between the wheels.
It may be difficult to drive due to the TCS limiting the
engine torque. In this case, engage the terrain-TCS.
Note!
Do not use terrain-TCS during
normal driving.
Note!
Switch off the TCS before towing
with any axle raised!
Note!
Switching off the TCS in the display
disables the TCS switch.
