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.
