4ETS (Electronic Traction System)
G
Warning
Observe "Important safety instructions"
(Y page 65).
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
®
.

Activate the off-road drive program
(Y page 204) or engage the LOW RANGE
off-road gear (Y page 157) if appropriate
for the driving conditions.
Off-road 4ETS (Electronic Traction
System)
A 4ETS system specifically suited to off-road
terrain is activated automatically if the off-
road drive program is activated
(Y page 204) or the LOW RANGE off-road
