and injure yourself and others.

If the lanes are narrow, the system may be unable to distinguish the neighboring lane from the one beyond it. For this reason, the system may indicate vehicles in the farther lane, especially if the vehicles are driving in a staggered formation in different lanes. In particular, this may be the case if the vehicles are driving at that edge of their lane which is nearest your vehicle. Due to the nature of the system: Rwarnings may be issued unnecessarily when driving close to crash barriers or similar solid lane borders.

Rthe warning may be interrupted when

traveling next to long vehicles for extended periods.

The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush around the sensors. For example, the radar sensors must not be covered by bicycle racks or overhanging loads. In the event of a severe impact or damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Blind Spot Assist may otherwise not work properly.

Information and warning display

: Yellow indicator lamp/red warning lamp If Blind Spot Assist is switched on, indicator lamps : in the exterior mirrors light up yellow up to a speed of 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 20 mph (30 km/h), warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if the reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G Warning Blind Spot Assist is not active at speeds under approximately 20 mph (30 km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to

Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the turn signal, a double warning tone sounds. Red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones.

Switching on Blind Spot Assist X Make sure that the radar sensor system

(Y page 217) and Blind Spot Assist (Y page 219) are activated in the on-board computer.

X Turn the key to position 2 in the ignition

lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5
seconds and then turn yellow.

Towing a trailer When you attach a trailer, make sure you have correctly established the electrical connection. This can be accomplished by checking the trailer lighting. In this event, Blind Spot Assist is deactivated. The indicator lamp lights up yellow in the exterior mirrors and the message: Blind Spot Assist Currently Unavailable See Operator's Manual appears in the multifunction display. i The indicator lamps in the exterior mirrors

can be switched off. To do this, you must deactivate Blind Spot Assist when: Rthe key is in position 2 in the ignition

lock.

Rthe engine is not running. Rthe electrical connection to the trailer

has been established.

Off-road driving systems 4MATIC (permanent four-wheel drive) 4MATIC ensures that all four wheels are permanently driven. Together with ESP® and 4ETS, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip. G Warning! If a drive wheel is spinning due to insufficient traction: RWhile driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The 4MATIC cannot prevent accidents resulting from excessive speed.

! Never tow the vehicle with one axle

raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground.

i In wintry driving conditions, the maximum

effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary.

! When testing the parking brake, operate the vehicle only briefly (for a maximum of ten seconds) on a brake test dynamometer. When doing this, turn the key to position 0 or 1 in the ignition. Failure to do this can cause damage to the drive train or the brake system.

! Function or performance tests may only be performed on a 2-axle dynamometer. If you wish to operate the vehicle on such a

DSR (Downhill Speed Regulation) Important safety guidelines DSR is an aid to assist you when driving downhill. It keeps the speed of travel at the speed selected on the on-board computer. The steeper the downhill gradient, the greater the DSR braking effect on the vehicle. When driving on flat stretches of road or on an uphill gradient, the DSR braking effect is minimal or non-existent. The speed is set to 4 mph (6 km/h) at the factory; you can adjust this in the on-board computer (Y page 219). G Warning! Downhill Speed Regulation (DSR) is a convenience system designed to assist the driver during vehicle operation. The system setting must be appropriate to the topographical and weather conditions encountered, which can change quickly. The driver is responsible for the vehicle speed and for safe brake operation at all times. Depending on the programmed speed, actual vehicle speed and gradient, switching on DSR while driving can cause the vehicle to slow down rapidly, and you may hear a sound, caused by the activation of the vehicle's brake system through DSR. Sudden and unexpected deceleration can result in loss of vehicle control, causing an accident and/or serious personal injury to you and others. Do not switch on DSR in a situation where rapid deceleration could result in a loss of vehicle control.

DSR controls the set speed when it is active and the automatic transmission is in the D,

R or N position. You can drive at a higher or a lower speed than that set on the on-board computer at any time by accelerating or braking. G Warning! If you depress the accelerator pedal with DSR activated, the vehicle can drive faster than the programmed set speed. You should therefore drive downhill with particular caution as it could lead to an accident and/or serious injury to you or others. Keep in mind that as soon as you remove your foot from the accelerator pedal with DSR switched on, DSR will start regulating the vehicle's speed including use of brakes if required. Depending on the programmed set speed, actual vehicle speed and gradient, DSR can cause the vehicle to slow down rapidly. Sudden and unexpected deceleration can result in loss of vehicle control, causing an accident and/or serious personal injury to you and others.

Information on "Off-road driving"; see (Y page 166).

During this procedure do not turn off the engine or shift the automatic transmission into another gear. If you do not wait until the shifting procedure has been entirely completed then it might not be correctly performed. The transfer case might be in neutral, thus interrupting the transfer of power between the engine and the drive axle. The vehicle is then freely movable, even if a gear has been selected, and could unintentionally be set into motion – particularly on up – or downhill grades. This could lead to an accident and cause injury to yourself and others. Please observe related messages appearing in the multifunction display.

196 Off-road driving systems

Differential lock General notes i Differential locks are available only in

vehicles with the Off-Road Pro engineering package.

Your vehicle is equipped with the following: RA differential lock for the transfer box: this controls the balance between the front and rear axles.

RA differential lock for the rear axle: this

controls the balance between the wheels and the rear axle.

Differential locks improve the vehicle's traction. 4ETS (Y page 67)controls the balance between the wheels on the front axle. Information on "Off-road driving"; see (Y page 166).

Information about the differential and differential locks When the vehicle is driving around a curve, the wheels on the outside of the curve have to cover a greater distance and therefore have to turn faster than the wheels on the inside. The differential, a transmission in the drive train, balances these different rotational speeds out, making cornering possible. The disadvantage of a differential: the wheels with the least grip are driven the hardest. Example: one wheel on a driven axle is on a snow-covered surface and therefore has no traction. This wheel has the most driving force, since the differential distributes most of the force to the wheel with the least resistance. The wheel on the opposite side of this axle, which is on a solid surface and could therefore enable traction, does not have any driving force. 4ETS eliminates this disadvantage and ensures good steerability by braking the spinning wheel automatically and thereby directing more force to the wheel that is on a solid surface and can provide traction.

ESP® and 4ETS are traction systems that are ideally suited to road driving and driving on easily negotiable off-road terrain. The LOW RANGE off-road gear also improves off-road capability. Difficult off-road conditions require additional measures, such as locking one or more differentials. Your vehicle has two differential locks: one (central) differential lock for the transfer case and one differential lock for the rear axle. Both differential locks can be activated using the selector wheel on the center console. When the (central) differential for the transfer case is locked, the speed of the front wheels is the same as the speed of the rear wheels. When the differential for the rear axle is locked, both of the rear wheels turn at the same speed, independent of their individual torques. Note that activating the differential locks significantly reduces the steerability of the vehicle. For your safety, the safety of others and to prevent damage to the vehicle, the differential locks must not be activated on paved roads. Note that the differential function is necessary when driving on paved roads and that the differentials must never be locked on paved roads. Otherwise, the vehicle can no longer be steered. The differential locks must therefore only be activated when driving off-road, and then only if activating the other driving systems (4ETS, ESP® and LOW RANGE off-road gear) is no longer sufficient.

Engaging the differential locks ! Drive off slowly when the differential

locks are engaged. Function or performance tests may only be performed on a 2-axle dynamometer. If you wish to operate the vehicle on such a dynamometer, please consult an authorized Mercedes-Benz Center beforehand. You could otherwise damage the drive train or the brake system.

! The differential locks must not be

activated when the vehicle is being towed or while the wheels are spinning.

Only engage the differential locks manually if traction in automatic mode is insufficient. At speeds of up to 19 mph (30 km/h), you can engage the differential locks manually. X Start the engine. X Turn selector wheel : to desired position

= or ?. The indicator lamp in selector wheel : lights up at the corresponding symbol. The engaged differential appears in the multifunction display:

A The differential lock for the transfer case

is locked.

If you have not previously selected the off- road menu (Y page 213) in the on-board computer, the message disappears after about five seconds. The differential locks are not controlled automatically. The steerability of the vehicle is restricted considerably. Drive carefully and accelerate gently for optimum traction. ! If the differential locks are activated manually, the wheels scuff on the road when cornering since the rotation difference between the wheels is no longer balanced out.

You can switch back to automatic mode at any time. For safety reasons, the differential locks disengage automatically at speeds above 31 mph (50 km/h). If you stop the vehicle and switch off the ignition for longer than ten seconds, the differential locks switch back to automatic mode.

Automatic mode Use automatic mode ; for all driving situations, including driving off-road or when fording. In automatic mode, the differential locks are engaged and disengaged according to driving requirements. This guarantees sufficient traction for most driving situations with unrestricted vehicle steerability. X Start the engine.

The differential locks are in automatic mode. The indicator lamp in selector wheel : lights up above symbol for automatic mode ;.

Engaging manually G Warning! Never drive on a paved surface with the center and rear axle differential locks manually engaged. Ability to steer the vehicle is greatly reduced when the differential locks are manually engaged, increasing the risk of an accident. For safety reasons, the locks are automatically released at a vehicle speed above 31 mph (50 km/h). Nevertheless, you should only manually lock the differential if absolutely necessary because engaged locks will restrict the vehicle drivetrain while cornering and cause the vehicle to chatter. This could cause you to lose control of the vehicle and cause an accident.

Towing a trailer Notes on towing a trailer Important safety instructions G Warning! Failure to use proper equipment and driving technique can result in a loss of vehicle control when towing a trailer. Improper towing or failure to follow the instructions in this manual can result in vehicle damage and/or serious personal injury. Follow the guidelines below carefully to assure safe trailer operation. Contact an authorized Mercedes-Benz Center should you require an explanation of information contained in this manual.

General information ROnly install an approved trailer coupling on

your vehicle. Further information on availability and on installation is available from any authorized Mercedes-Benz Center.

RThe bumpers of your vehicle are not

suitable for installing detachable trailer couplings.

RDo not install hired trailer couplings or

other detachable trailer couplings on the bumpers of your vehicle.

RTo reduce the risk of damage to the ball

coupling, remove it from the ball coupling recess when not in use.

Coupling up a trailer G Warning! Vehicles with air suspension program: 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.

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.

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,

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.

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

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 air suspension program: 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.

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.

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 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.

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! HYBRID vehicles: It is imperative that you read the HYBRID Supplemental Operating Instructions included in your vehicle literature portfolio. You may otherwise not receive all necessary safety information and warning for the operation of your vehicle. 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.

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.

Speedometer with segments The segments in the speedometer indicate which speed range is available. DISTRONIC mode: One or two segments around the stored speed light up.

Operating the on-board computer The on-board computer is activated as soon as you turn the SmartKey to position 1 in the ignition lock. You can control the multifunction display and the settings in the on-board computer using the buttons on the multifunction steering wheel.
