2011 Mercedes-benz R Class Owners Manual

Make sure that you do not operate the ADS switch or the vehicle level control system when coupling/decoupling the trailer.

Observe the maximum permissible trailer dimensions (width and length). Most federal states and all Canadian provinces require by law: Rsafety chains between the towing vehicle and the trailer. The chains should be cross- wound under the trailer drawbar. They must be fastened to the vehicle's trailer coupling, not to the bumper or the axle. Allow for enough play in the chains to facilitate turning tight corners.

Ra separate brake system for certain types

of trailer.

Ra safety switch for braked trailers. Check the specific legal requirements applicable to your federal state. If the trailer detaches from the towing vehicle, the safety switch applies the trailer's brakes.

! Do not connect the trailer's brake system (if featured) to the hydraulic brake system of the towing vehicle, as the latter is equipped with an anti-lock brake system. Doing so will result in a loss of function of the brake systems of both the vehicle and the trailer.

i The vehicle's wiring harness features a

line to the brake indicator lamp.

X Make sure that the automatic transmission

is set to position P.

X Apply the vehicle's parking brake. X Start the engine. X Vehicles with the AIRMATIC package:

select highway level and set ADS to AUTO or COMF.

X Switch off the engine. X Close all doors and the tailgate. X Couple up the trailer. X Establish all electrical connections.

i Vehicles with the AIRMATIC package: with a trailer attached, the vehicle will always remain at highway level. When coupling up a trailer, please observe the following: Rif highway level has not been set

manually, the vehicle will automatically sink to highway level as soon as it reaches a speed of 5 mph (8 km/h).

Rhigh-speed level is not available. These restrictions apply to all accessories powered through a connection to the trailer power socket of your vehicle, e.g. a bicycle carrier.

Towing a trailer There are numerous legal requirements concerning the towing of a trailer, e.g. speed restrictions. Make sure that your vehicle/ trailer combination complies with the local requirements not only in your area of residence but also at any location to which you are traveling. The police and local authorities can provide reliable information. Please observe the following when towing a trailer: RTo acquaint yourself with driving with a trailer and with the resulting changes to handling, you should practice cornering, stopping and reversing in a traffic-free location.

RBefore driving, check: the trailer coupling the safety switch for braked trailers the safety chains the electrical connections the lights the wheels

RAdjust the exterior mirrors to provide an

unobstructed view of the rear section of the trailer.

RIf the trailer features electronically

controlled brakes, pull away the vehicle/

trailer combination carefully, manually 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 air- conditioning 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.

Decoupling a trailer G Warning! Vehicles with AIRMATIC: While you are coupling or decoupling a trailer, make sure nobody locks or unlocks the vehicle and/or opens or closes doors or the tailgate. The vehicle’s level could change and you could endanger yourself and/or others as a result. Make sure that you do not operate the ADS switch or the vehicle level control system when coupling/decoupling the trailer.

X Make sure that the automatic transmission

is set to position P.

X Apply the vehicle's parking brake. X Start the engine. X Close all doors and the tailgate. X Apply the trailer's parking brake. G Warning! Vehicles with AIRMATIC: As soon as you disconnect the electrical connection between the trailer and the vehicle, the vehicle will lower. To help avoid personal injury, make sure no one is near the wheel housing or underneath the vehicle before the electrical connection is disconnected. When you decouple the trailer, the vehicle is temporarily raised because the springs are relieved of load. Be especially careful during this process, as you could otherwise injure yourself and/or others. Make sure that any

196 Towing a trailer

Vehicle Weight Rating (GVWR) is specified on the type plate located on the B-pillar on the driver's side of your vehicle.

i Mercedes-Benz recommends loading the

trailer so that the drawbar noseweight remains between 8% and 10% of the permissible gross trailer weight.

i The weight of additional accessories,

passengers, and cargo reduces the permissible trailer load and drawbar noseweight for your vehicle.

Checking the vehicle and trailer weight RTo check that the weights of the towing vehicle and the trailer comply with the maximum permissible values, have the vehicle/trailer combination (including the driver, passengers, and cargo with a fully laden trailer) weighed on a calibrated weighbridge.

RCheck the permissible axle weight of the

front and rear axle, the Gross Trailer Weight (GTW), and the drawbar noseweight. Check the permissible axle weight of the front and rear axle, the Gross Trailer Weight (GTW), and the drawbar noseweight.

Trailer power supply The trailer power socket of your vehicle is designed for connecting the 7-pin connector supplied as part of the Mercedes-Benz- approved trailer coupling. i Depending on your trailer, you may need

an adapter to connect your trailer to the vehicle.

Further information is available from any authorized Mercedes-Benz Center.

persons remaining in the vehicle do not press the switches for vehicle level control or the ADS.

X Switch off the engine.

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: 350 lb (158 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. The permissible Gross Vehicle Weight Rating (GVWR) is specified on the type plate located on the B-pillar on the driver's side of your vehicle. You can find the maximum permissible values on the type plates of your vehicle and the trailer. Always observe the lowest respective value when determining the maximum weight with which you can load the vehicle and the trailer.

RThe drawbar noseweight acting on the ball coupling has to be added to the rear axle weight in order to prevent the permissible Gross Axle Weight Rating (GAWR) from being exceeded. The permissible Gross

Vehicle equipment

i This manual describes all the standard and optional equipment of your vehicle which was available at the time of purchase. Country-specific differences are possible. Bear in mind that your vehicle may not feature all functions described here. This also refers to safety-related systems and functions.

Important safety guidelines

You will find an illustration of the instrument cluster in the "At a glance" section (Y page 28). G Warning A driver's attention to the road and traffic conditions must always be his/her primary focus when driving. For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely. Bear in mind that at a speed of just 30 mph (approximately 50 km/h ), your vehicle is covering a distance of 44 feet (approximately 14 m) every second. G Warning! No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired.

If you must continue to drive, do so with added caution. Contact an authorized Mercedes- Benz Center as soon as possible. G Warning Malfunction and warning messages are only indicated for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.

Displays and operation Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as

this could damage the engine.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display The outside temperature display is in the multifunction display. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

Changes in the outside temperature are displayed after a short delay.
