Electronic Traction System (ETS)
G
Observe Safety notes, see page 55.
The ETS (Electronic Traction System) is a
component of the ESP
® . The ETS improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
When you switch off the ESP
® , the ETS is still
enabled.
Switching the ESP ® off or on (except
SL 63 AMG)
G
Warning!
The ESP ® should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP
® when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP
® . This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
R
when driving with snow chains
R
in deep snow
R
in sand or gravel
G Warning!
Switch on the ESP ® immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP
® will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning.
When you switch off the ESP ® ,
R the ESP ® will not stabilize the vehicle
R
the engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip

spinning wheel
R the ESP ® continues to operate when you
are braking
R the cruise control or the Distronic system
cannot be activated
R
the cruise control or the Distronic system
switch off if activated
i When the ESP ® is switched off and one or
more drive wheels are spinning, the ABS/
ESP
® warning lamp ÷ or d 8 in the
instrument cluster flashes. However, the
ESP
® will then not stabilize the vehicle.
Depending on vehicle production date, the
symbol on the ESP
® switch may differ.
