R
While driving, ease up on the accelerator
pedal.
R
Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP
®
cannot
prevent accidents resulting from excessive
speed.
!
Vehicles with 4MATIC:
Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system or the transfer case which is not
covered by the Mercedes-Benz Limited
Warranty.
!
Vehicles with 4MATIC:
Because the ESP
®
operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position 0 or
1 or KEYLESS-GO start/stop button in
position 0 or 1) when the parking brake is
being tested on a brake test dynamometer.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.

Electronic Traction System
(ETS/4-ETS)
G
Observe Safety notes, see
page 70.
The ETS (Electronic Traction System) and
4-ETS (four-wheel Electronic Traction
System, vehicles with 4MATIC only) are
components of the ESP
®
. The ETS/4-ETS
improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. Vehicles with 4MATIC also
transfer more power to the wheel(s) with
traction.
Except E 63 AMG:
When you switch off the ESP
®
, the
ETS/4-ETS is still enabled.
