158 Towing a trailer brake using the brake controller, and check the brakes for correct function. RSecure any objects on the trailer to prevent the cargo from slipping when the vehicle is in motion. RIf you couple up a trailer, regularly check the cargo for secure fastening and make sure that the trailer lamps and (if applicable) the trailer brakes are functioning correctly. RBear in mind that the handling will be less stable when towing a trailer than when driving without one. Avoid sudden steering movements. RThe vehicle/trailer combination is heavier, accelerates more slowly, has a decreased gradient climbing capability and a longer braking distance. It is more susceptible to side winds and requires more careful steering. RIf possible, avoid abrupt braking. Depress the brake pedal moderately at first, so that the trailer can activate its own brakes. Then increase the pressure on the brake pedal. RIf the automatic transmission continues to shift back and forth between two gears when driving up or downhill, restrict the shift range. Select shift range 4, 3, 2, or 1. A lower gear and lower speed reduce the risk of engine failure. RWhen driving downhill, shift to a lower gear to utilize the engine's braking effect. Avoid continuous brake application as this may overheat the vehicle brakes and, if installed, the trailer brakes. RIf the coolant temperature increases dramatically while the air-conditioning system is switched on, switch off the airconditioning system. Coolant heat can additionally be dissipated by opening the windows and by setting the blower fan and the interior temperature to maximum. RWhen overtaking, pay particular attention to the extended length of your vehicle/ trailer combination. Due to the length of your vehicle/trailer combination, you will have to travel an additional distance beyond the vehicle you are overtaking before returning to the previous lane.

Permissible trailer load and drawbar noseweight Weight specifications The Gross Trailer Weight (GTW) is the combined weight of the trailer together with the cargo and equipment loaded on the trailer. Permissible gross weight: 3500 lb (1588 kg). The permissible Trailer drawbar Weight Rating (TWR) is the maximum weight permitted on the trailer drawbar: 280 lb (127 kg) limit for Mercedes-Benz-approved trailer couplings. Loading a trailer RWhen loading a trailer, please note that neither the permissible gross trailer weight nor the permissible Gross Vehicle Weight Rating (GVWR) may be exceeded.
