ETS traction control is part of ESP ® . On vehi-
cles with 4MATIC, 4ETS is part of ESP ® .
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP ® .

G WARNING
If ESP ® is malfunctioning, ESP ® is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
® checked at a
qualified specialist workshop.
! If you test the parking brake using a brake
dynamometer, switch the ignition off.
Application of the brakes by ESP ® may oth-
erwise destroy the brake system.
When towing the vehicle with the rear axle
raised, observe the notes on ESP ®
(
Y
page 353).
ESP ® is deactivated if the warning lamp å
in the instrument cluster lights up and:
R
the vehicle is moving
R the ECO start/stop function is activated
If the ÷ warning lamp lights up continu-
ously, ESP ® is not available due to a malfunc-
tion.
Observe the information on warning lamps
(
Y
page 288) and display messages which
may be shown in the instrument cluster
(
