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 slippery road
conditions, by applying power to all four
wheels.
Warning! G
If you see the ESP
®
warning lamp v

as follows:
ț While driving off, apply as little throttle
as possible.
ț While driving, ease up on the accelera-
tor.
ț 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 result-
ing from excessive speed.

Because the ESP
®
operates automatically,
the engine and the 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 oth-
erwise seriously damage the brake system.
Operational tests with the engine running can
only be conducted on a two-axle dynamometer.
