Switching off the ESP
®
To improve the vehicle’s traction, switch
off the ESP
®
in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
ț when driving with snow chains
ț in deep snow
ț in sand or gravel
Warning! G
The ESP
®
cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of an ESP
®
equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
!
Operational or performance test must only
be conducted on a two-axle dynanometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!
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 testing the brakes on a
brake test dynamometer and 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.
i
The ESP
®
will only function properly if you
use wheels of the recommended tire size
(
୴ page 536).
Warning! G
The ESP
®
should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Do not switch off the ESP
®
when a spare
wheel is mounted.
