Four Wheel Electronic Traction System (4MATIC)
with Electronic Stability Program (ESP)
(Model with All Wheel Drive [AWD])
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.
Important!
If the ESP warning lamp flashes:
• during take-off, apply as little throttle as possible,
• while driving, ease up on the accelerator.
Adapt your speed and driving to the prevailing road
conditions.
Caution!
Operational tests with the engine running can only be
conducted on a 2-axle dynamometer.Otherwise the ESP
will immediately be engaged and will apply the brakes
to the spinning wheels.
If the vehicle is towed with one axle raised (see
page 282), or when testing the parking brake on a brake
test dynamometer, the engine must be shut off
(electronic key in steering lock position 0 or 1).
If one or more wheels tend to spin, ESP will apply the
brakes to them. The traction control for the front axle
wheels deactivate at approximately 50 mph (80 km/h),
and for the rear axle wheels at approximately 80 mph
(130 km/h).
The warning lamp in the speedometer blinks at any
speed as soon as one tire loses traction.
Note:
In winter operation, the maximum effectiveness of the
4MATIC is only achieved with Mercedes-Benz
recommended M+S rated radial-ply tires and/ or snow
chains.
