Switching TCS on and off
Fig. 162
In the centre console: button for switching TCS on and off manually.
If the vehicle does not have sufficient traction, you can switch off TCS in the following situations:
• When driving in deep snow or on loose surfaces.
• When rocking the vehicle backwards and forwards to free it from mud.
Then switch the TCS function back on.
Switching TCS or ESC Sport on and off
Depending on the vehicle equipment, TCS and ESC Sport can be switched off via the Infotainment
system or using the
button

When the TCS is switched off, ESC Sport is switched on, or the Off-road or Off-road Individual
driving profiles are active, the
yellow
indicator lamp
is shown on the instrument cluster display.
The intelligent technology used in brake support systems cannot overcome the laws of
physics, and functions only within the limits of the system. Driving fast on icy, slippery or
wet roads can lead to a loss of control of the vehicle and could cause serious injury to the
driver and passengers.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions. Do not let the extra safety afforded by the brake support systems anti-lock
brake system, brake assist system, EDL, TCS and ESC tempt you into taking any risks
when driving.
• The brake support systems cannot defy the laws of motion. Slippery and wet roads will
remain dangerous, even when the ESC and other systems are active.
• Driving too fast on wet roads can cause the wheels to lose contact with the road
surface and aquaplane. The vehicle cannot be braked, steered or controlled once it has
lost contact with the road surface.
• Brake support systems cannot prevent an accident if e.g. you are driving too close to
the vehicle in front or are driving too fast for the specific driving situation.
• Although the brake support systems are very effective and can help to control the
vehicle in difficult driving situations, please always remember that the driving stability
of the vehicle depends on the tyre grip.
• When accelerating on a slippery surface, e.g. on ice and snow, press the accelerator
carefully. The wheels can spin even when brake support systems are active, and this
can lead to a loss of control of the vehicle.
WARNING
The effectiveness of ESC can be reduced considerably if other components and systems
which affect driving dynamics are not serviced properly or are not functioning properly.
This also applies, but not exclusively, to the brakes, tyres and other systems named
above.
• Please always note that modifications and changes to the vehicle can affect the
function of the anti-lock brake system, brake assist system, TCS, EDL and ESC.
• Alterations to the suspension system or the use of non-approved wheel and tyre
combinations can affect the function of the anti-lock brake system, brake assist
system, EDL, TCS and ESC and reduce their effectiveness.
• Suitable tyres are also crucial if ESC is to function optimally

WARNING
Driving without the brake servo can considerably increase the braking distance and thus
cause accidents and serious injuries.
• Never allow the vehicle to roll if the engine is switched off.
• If the brake servo does not function or the vehicle is being towed, the brake pedal will
have to be depressed more forcefully as the braking distance will be increased due to
the lack of assistance for the brake system.
