Driving tips
Observe the information on ESP® trailer stabilization (Y page 64) and on pulling away with a trailer.
The maximum permissible speed for vehicle/ trailer combinations depends on the type of trailer. Before beginning the journey, check the trailer's documents to see what the maximum permitted speed is. Observe the legally prescribed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maximum permissible rear axle load is increased when towing a trailer. Refer to the "Technical data" section to find out whether this applies to your vehicle. If you utilize any of the added maximum rear axle load when towing a trailer, the vehicle/trailer combination may not exceed a maximum speed of 60 mph(100 km/h) for reasons concerning the operating permit. This also applies in countries in which the permissible maximum speed for vehicle/trailer combinations is above 60 mph(100 km/h).
When towing a trailer, your vehicle's handling characteristics will be different in comparison with when driving without a trailer.
On long and steep downhill gradients, you must select shift range 1, 2 or 3 in good time.
This also applies if you have activated cruise control or DISTRONIC PLUS.
This will use the braking effect of the engine, so that less braking will be required to maintain the speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If you need additional braking, depress the brake pedal repeatedly rather than continuously.
