Four-wheel electronic traction system (4-ETS+)

With the key in steering lock position 2, the yellow
4-ETS+ malfunction indicator lamp

{ and the 4-ETS+

warning lamp

v come on and should go out when

the engine is running.

The 4-ETS+ improves vehicle’s ability to utilize available
traction, especially under slippery road conditions. The
brakes are applied to the spinning wheel and power is
transferred to the wheel(s) with traction.
The traction control engages at vehicle speeds up to
approx. 24 mph (40 km/h), and switches off at
50 mph (80 km/h).

The 4-ETS+ warning lamp

v, located in the

speedometer dial, starts to flash at any vehicle speed, as
soon as the tires lose traction and the wheels begin to
spin.

Important!

If the 4-ETS+ warning lamp

v 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.

4-ETS+ Control

If the yellow 4-ETS+ malfunction indicator lamp

{

comes on while the 4-ETS+ warning lamp

v flashes,

the electronic traction system is being switched off
temporarily to prevent overheating of the drive wheel
brakes.

If the 4-ETS+ malfunction indicator lamp

{ comes on

with the engine running, a malfunction has been
detected.

Have the 4-ETS+ checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.

With the ABS malfunctioning, the 4-ETS+ is also
switched off.

Caution!

If the vehicle is towed with the front axle raised (see
towing the vehicle on page 277), or when testing the
parking brake on a brake test dynamometer, the engine
must be shut off (key in steering lock position 0 or 1).
Otherwise, the electronic traction system will
immediately be engaged and will apply the rear wheel
brakes.
