Whether slippery surfaces or steep declines – you can always rely on the Sprinter 4x4 and Vito 4x4 all-wheel drive vans. Even steep tilts and extremely high passes are no obstacle at all for the two vans from Mercedes-Benz. Commercial use demands excellent traction where jobs involve muddy construction pits, uneven terrain, snow and ice. Yet the Sprinter 4x4 and the Vito 4x4 remain effective and safe even under difficult conditions. While the all-wheel drive Sprinter is the uncontested innovation leader among the 3.5 tonne vans, the Vito is actually the only mid-size van available with permanent all-wheel drive. The 4ETS traction control is fully integrated into the ADAPTIVE ESP electronic stability program. This enables 4ETS to optimally supplement the existing functions of the standard safety systems by preventing yawing movements around the vertical axis, significantly improving driving stability as a consequence. The traction control not only reduces the automatic locking among the axles but also prevents the brake system from overheating. A control light signals these functions to the driver. Naturally, the Vito 4x4 and Sprinter 4x4 also retain the other functions of the ADAPTIVE ESP such as the ABS anti-blocking system, ASR traction control, EBV electronic brake force distribution, the BAS brake assistant and the AAS start assist.
