80 Safety and SecurityDriving safety systemsSwitching off the ESP
To improve the vehicle's traction, turn 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:

starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


sand or gravelThe switch is located on the center con-
sole.

stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.iDistronic* cannot be activated when
ESP has been deactivated.
!Avoid spinning of a drive wheel for an
extended period with the ESP switched
off. This may cause serious damage to
the drivetrain which is not covered by
the Mercedes-Benz Limited Warranty.Warning!

status of the ESP.

81 Safety and Security
Driving safety systems
Four wheel electronic traction system (4MATIC) with the ESP
Models with all-wheel drive only:
The 4MATIC improves the vehicle’s ability
to use available traction, e.g. during winter
operation in mountains under snowy con-
ditions, by applying power to all four
wheels.
Warning!
G
If you see the ESP warning lamp
v
flash-
ing in the speedometer dial, proceed as fol-
lows:


While driving off, apply as little throttle
as possible


While driving, ease up on the accelera-
tor


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.!Do not tow with one axle raised.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
!Performance testing must only be con-
ducted on a 2-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Because of the ESP’s automatic opera-
tion, the engine must be shut off
(SmartKey in starter switch position0
or1) when the parking brake is being
tested on a brake test dynamometer.
Active braking action through the ESP
may otherwise seriously damage the
front or rear axle brake system.
Operational tests with the engine run-
ning can only be conducted on a 2-axle
dynamometer.

You can open a locked door from the in-
side. Open door only when conditions are
safe to do so.You can deactivate the automatic locking
using the control system (
page 155).
iIt is not necessary to slam the door or
trunk lid closed. A pneumatic pow-
er-assisted mechanism draws doors
and trunk lid closed quietly and auto-
matically once door and trunk lid has
been latched. When the pneumatic
power-assisted mechanism has
stopped, doors and/or trunk can be
re-opened.
Warning!

To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk opening when closing a door or the
trunk lid. Be especially careful when small
children are around.
The pneumatic power closing assist mecha-
nism cannot be interrupted once it has been
engaged.
To prevent personal injury, never actuate
the closing assist mechanism by tampering
with the door or trunk lid latch.
iThe doors unlock automatically after an
accident if the force of the impact ex-
ceeds a preset threshold.
The vehicle automatically locks when
the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or
more. You could therefore lock yourself
