Warning!
Never switch off the ESP
®
when you see the
ESP
®
warning lamp v flashing in the
instrument cluster. In this case proceed as
follows:
R
When driving off, apply as little throttle
as possible.
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.
!
Because the ESP
®
operates automati-
cally, 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
or when the vehicle is being towed with the
front axle raised.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the Mer-
cedes-Benz Limited Warranty.
!
The ESP
®
will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i
The Distronic system and cruise control
switch off automatically when the ESP
®
engages.
For more information, see the “Practical
hints” section (Y page 256) and
(Y page 293).
Electronic Traction System (ETS)
G
Observe Safety notes, see
page 64.
The ETS (Electronic Traction System) is a
component of the ESP
®
. The ETS improves
the vehicle’s ability to utilize available trac-
tion, especially under slippery road condi-
tions by applying the brakes to a spinning
wheel.
Except CLS 63 AMG:
When you switch off the ESP
®
, the ETS is still
enabled.

The ESP
®
should not be switched off during
normal driving other than in the circum-
stances described below. Disabling the sys-
tem will reduce vehicle stability in driving
maneuvers.
Do not switch off the ESP
®
when a spare
wheel is mounted.
