Important safety notes
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time.
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even
rollover. There is a risk of an accident.
On no account should you attempt to straighten up the vehicle/trailer combination by increasing the speed. Reduce vehicle speed and do not countersteer. Apply the brake as necessary.
WARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in
question is longer or angled differently. This
could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident.
Only install the ball coupling delivered with the vehicle or a ball coupling that is designed to meet your trailer towing requirements. Do not modify the ball coupling or the trailer tow hitch.
WARNING
If the ball coupling is not installed correctly or
not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as described. Before every journey, ensure that the ball coupling is secured with the bolt and the corresponding spring cotter.
Please observe the manufacturer's operating instructions for the trailer coupling if a detachable trailer coupling is used.
You will find the applicable permissible values, which must not be exceeded, in the vehicle documents. You will find the values approved by the manufacturer on the vehicle identification plates and those for the towing vehicle in the "Technical data" section .
Couple and uncouple the trailer carefully. If you do not couple the trailer to the towing vehicle correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
• the permissible trailer drawbar noseweight
• the permissible trailer load
• the permissible rear axle load of the towing
vehicle
• the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When towing a trailer, your vehicle's handling characteristics will be different in comparison with when driving without a trailer.
The vehicle/trailer combination: • is heavier • is restricted in its acceleration and gradient-climbing capability • has an increased braking distance • is affected more by strong crosswinds • demands more sensitive steering • has a larger turning circle
This could impair the handling characteristics.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do not exceed the maximum permissible speed for your vehicle/trailer combination.
General notes
R Do not exceed the legally prescribed maximum speed for vehicle/trailer combinations in the relevant country.
This lowers the risk of an accident.
• Only install an approved trailer coupling on your vehicle.
Further information on availability and on installation is available from any authorized Mercedes-Benz Center.
R The bumpers of your vehicle are not suitable for installing detachable trailer couplings.
• Do not install hired trailer couplings or other detachable trailer couplings on the bumpers of your vehicle.
• If you do not need the ball coupling, remove the ball coupling from the ball coupling recess. This reduces the risk of damage to the ball coupling.
When towing a trailer, set the tire pressure on the rear axle of the towing vehicle for a maximum load; see the tire pressure table in the fuel filler flap .
You will find installation dimensions and loads in the technical data .
The maximum permissible trailer drawbar noseweight on the ball coupling for up to 3 persons is 562 lbs (255 kg). The maximum permissible trailer drawbar noseweight for more than 3 persons and the maximum load in the trunk can be found in the trailer drawbar noseweight table .
However, the actual noseweight must not exceed the value given on the trailer tow hitch or trailer identification plates. The lowest weight applies.
When towing a trailer, set the tire pressure on the rear axle of the towing vehicle for a maximum load; see the tire pressure table in the fuel filler flap .
Please note that when towing a trailer, PARKTRONIC and Blind Spot Assist are only available with limitations, or not at all.
On vehicles without level control, the height of the ball coupling will alter according to the load placed on the vehicle.
If necessary, use a trailer with a heightadjustable drawbar.
Driving tips
► On long and steep downhill gradients, select shift range 1, 2 or 3 in good time.
This also applies if you have activated cruise control or SPEEDTRONIC.
► If necessary, shift the transfer case to LOW RANGE.
This will use the braking effect of the engine, so that less braking will be required to maintain the speed. which 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.
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 to when driving without a trailer and it will consume more fuel.
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. which 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.
Driving tips
If the trailer swings from side to side: ► Do not accelerate.
► Do not counter-steer.
► Brake if necessary.
R Maintain a greater distance from the vehicle in front than when driving without a trailer.
• Avoid braking abruptly. If possible, brake gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
• The values given for gradient-climbing capabilities from a standstill refer to sea level. When driving in mountainous areas, note that the power output of the engine, and consequently the vehicle's gradientclimbing capability, decrease with increasing altitude.
