Mercedes-Benz M-Class 2010 Owners Manual - Manual (Page 66)

G Warning!
Never switch off the ESP ® when you see the
ESP ® warning lamp d 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.
! 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 without 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
or the vehicle is being towed with one axle
raised.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system 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.
Such testing should be no longer than 10
seconds.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-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 cruise control switches off
automatically when the ESP ® engages.
Electronic Traction System
(ETS/4-ETS)
G Observe Safety notes, see page 62.
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.
When you switch off the ESP
® , the
ETS/4-ETS is still enabled.
X If conditions require, switch on the off-road
driving program (
Y page 155).
Off-road 4-ETS (vehicles with 4MATIC)
With the off-road driving program switched on
(
Y page 155), the 4-ETS designed for off-road
use is activated automatically.
