2012 Mercedes-benz GL Class Owners Manual

RBefore driving, check: the trailer tow hitch 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

212 Trailer towing

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.

ROn long and steep gradients that are difficult to drive down in shift range 1, switch to the off-road drive program or engage the LOW RANGE off-road gear.

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

X Remove the trailer cable and decouple the

trailer.

X Switch off the engine.

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 gross axle weight rating 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.

Permissible trailer loads and drawbar noseweights 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: 7500 lb (3402 kg). The permissible Trailer drawbar Weight Rating (TWR) is the maximum weight permitted on the trailer drawbar: 600 lb (272 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 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 15% of the permissible gross trailer weight.

i The weight of additional accessories,

passengers, and cargo reduces the

Important safety notes

You will find an illustration of the instrument cluster in the "At a glance" section (Y page 29). 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
