ETS/4ETS (Electronic Traction System)
i Observe the "Important safety notes"
section ( Y page 67).
ETS/4ETS traction control is part of ESP ® .
Traction control brakes the drive wheels
individually 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
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP
® .

WARNING
If ESP ® is malfunctioning, ESP ® is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
® checked at a
qualified specialist workshop.
! When testing the electric parking brake
on a braking dynamometer, switch off the
ignition. Application of the brakes by
ESP
® may otherwise destroy the brake
system.
Vehicles without 4MATIC: observe the notes
on ESP
® ( Y page 324) when towing the
vehicle with a raised rear axle.
! Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. Before you
operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage
the drive train or the brake system.
ESP ® is deactivated if the å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP
® is not
available due to a malfunction.
Observe the information on warning lamps
(
Y page 265) and display messages which
may be shown in the instrument cluster
(
Y page 236).
i Only use wheels with the recommended
tire sizes. Only then will ESP ® function
properly.
Characteristics of ESP
General information
If the ÷ ESP warning lamp goes out before

If ESP
® intervenes, the ÷ ESP ® warning
lamp flashes in the instrument cluster.
If ESP
® intervenes:
X Do not deactivate ESP ® under any
