Four wheel electronic traction system
(4MATIC) with the ESP
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
conditions, by applying power to all four
wheels.
Warning! G
If you see the ESP warning lamp v flash-
ing in the speedometer, proceed 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 resulting
from excessive speed.

Because of the ESP’s automatic opera-
tion, the engine and ignition must be
shut off (SmartKey in starter switch

when the parking brake is being tested
on a brake test dynamometer.
Active braking action through ESP may
otherwise seriously damage the front
or rear axle brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.
