Cornering, going into and coming out of a bend

DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles

The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late. Vehicles traveling on a different line

DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles

DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short. Other vehicles changing lanes

DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these.

186 Driving systems

Crossing vehicles

DISTRONIC PLUS may detect vehicles that are crossing your lane by mistake. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.

Monitoring range of the sensors

Blind Spot Assist monitors the area up to 10 ft (3 m) behind your vehicle and directly next to your vehicle, as shown in the diagram. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if the vehicles are driving on the inner side of their lane. Due to the nature of the system: Rwarnings may be issued in error when

driving close to crash barriers or similar solid lane borders.

Rthe warning is canceled when driving for an extended period next to long vehicles, such as trucks.

The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free from dirt, ice or slush around the sensors. The rear sensors must not be covered, for example by bicycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop. Blind Spot Assist may otherwise not work properly.

General notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle which are in back of the driver. A

warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lanes, you will also receive an optical and audible collision warning. If a risk of lateral collision is detected, corrective braking may help you avoid a collision. To support the course- correcting brake application, Active Blind Spot Assist also uses the forward-facing radar sensor system. Active Blind Spot Assist supports you from a speed of approximately 20 mph(30 km/h).

Monitoring area G WARNING Active Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course. If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

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 reverse gear is engaged. In this event, Active Blind Spot Assist is no longer active.

Active Blind Spot Assist monitors the area up to 10 ft (3.0 m) behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles driving at the inner edge of their lanes. Due to the nature of the system: Rwarnings may be issued in error when

driving close to crash barriers or similar solid lane borders.

Rwarnings may be interrupted when driving

alongside particularly long vehicles, for example trucks, for a prolonged time.

Two Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers respectively. An additional radar sensor is located behind the cover in the radiator grill. Make sure that the bumpers and the cover in the radiator grill are free of dirt, ice or slush. The rear sensors must not be covered, for example by cycle racks or overhanging cargo. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified

Visual and audible collision warnings

You are responsible for driving at appropriate speeds, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

When you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision warning. You then hear a double warning tone and 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.

Course-correcting brake application G WARNING Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the course-correcting brake application is not sufficient to avoid a collision. In such a case, you must steer, brake or accelerate. In very rare cases, the system may erroneously detect a danger of collision in the area of crash barriers or similar lane borders and apply the brakes. Active Blind Spot Assist does not detect all traffic situations and road users. Always make sure that there is sufficient distance on the side for other traffic or obstacles. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate.

If a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and a dual warning tone sounds. In addition, display ; appears in the multifunction display. If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is meant to assist you in avoiding a collision. The course-correcting brake application is available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h).

192 Driving systems

4MATIC (permanent four-wheel drive) ! 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.

! 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 SmartKey to position 0 or 1 in the ignition. Failure to do this can cause damage to the drive train or the brake system.

! A function or performance test should

only be carried out on a two-axle dynamometer. Before you operate the vehicle on such a dynamometer, please consult a qualified workshop. You could otherwise damage the drive train or the brake system.

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. If a drive wheel spins due to insufficient grip: ROnly depress the accelerator pedal as far

as necessary when pulling away.

RAccelerate less when driving. If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override the laws of physics. 4MATIC cannot take account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane. Only engage 4MATIC when the current road, weather and traffic conditions permit it to be done safely, and adapt your driving style accordingly. Drive carefully and maintain a suitable distance to the vehicle in front.

PARKTRONIC is activated automatically when you: Rswitch on the ignition Rshift the transmission to position D, R or N Rrelease the parking brake PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.

Range of the sensors General notes

: Example: sensors in the front bumper,

left-hand side

Side view

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.

For information about driving off-road, see (Y page 164).

PARKTRONIC Important safety notes ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and other objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain.

PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. Check in front, behind and to the sides of the vehicle before maneuvering, parking or exiting a parking space. There must not be any persons, animals or objects in the area in which you are maneuvering. PARKTRONIC cannot identify any persons or objects outside of the detection range. As a result, PARKTRONIC cannot warn you about objects in this area.

Differential locks General notes G WARNING When differential locks are engaged on a firm, high-grip surface, the vehicle's steerability is greatly impaired. In particular, engaging the differential locks when cornering could lead to you losing control of the vehicle. There is a risk of an accident. Disengage the differential locks immediately on firm, high-grip surfaces. G WARNING ABS, 4ETS, ESP® and BAS are deactivated while the differential locks are engaged. As a result, the wheels could lock when braking and the braking distance is increased. There is a risk of an accident. Disengage the differential locks immediately on firm, high-grip surfaces.

! In order to avoid damage to the transfer

case, you must operate the vehicle on a dynamometer (1-axle dynamometer) only if: Rthe axle not driven on is jacked up

or

Rthe corresponding propeller shaft is disconnected and the transfer case differential lock is activated.

Otherwise, the transfer case can be damaged. Differential locks improve the traction of the vehicle.

Your vehicle is equipped with a differential lock for: Rthe transfer case: this controls the balance

between the front and rear axles.

Rthe rear axle: this controls the balance between the wheels on the rear axle.

Rthe front axle: this controls the balance between the wheels on the front axle.

Information on differential and differential locks When the vehicle drives around a curve, the wheels on the outside of the curve must cover a greater distance. Therefore, the wheels turn more rapidly than on the inside. The differential, a transmission in the drive train, compensates for these different rotational speeds, making cornering possible. The disadvantage of a differential is that more power is transferred to the wheels that have the least grip. An example: a wheel of a driven axle is on a snow-covered surface and therefore does not have any traction. The differential causes this wheel to be subjected to the strongest driving force, as the flow of force takes the path of least resistance. The opposite wheel on this axle, however, which stands on firm ground and could therefore allow propulsion, receives no driving power. 4ETS compensates for this disadvantage. 4ETS provides good steerability by automatically braking the spinning wheel. 4ETS provides the wheel on the firm surface with more drive force, which in turn provides propulsion. ESP® and 4ETS are traction systems that are ideal for road driving and suitable for light off- road driving. The LOW RANGE off-road gear also improves off-road capability. Moreover, the more difficult conditions in off- road driving require further measures such as locking one or several differentials. Your vehicle is equipped with three differential locks:

202 Off-road driving systems

Ra central differential lock for the transfer

case,

Ra differential lock for the front axle and Ra differential lock for the rear axle. Each differential lock can be engaged with the respective switch on the center console. If the transfer case differential is disabled, the front and rear wheels turn at the same speed. If the differential for the rear axle is locked, both rear wheels turn at the same speed, regardless of their individual torques. Please note that activating the differential locks severely restricts the vehicle's steerability. Please note that the functions of the differential are absolutely necessary for driving on paved roads. The differential locks must never be engaged when driving on paved roads. Otherwise, the vehicle may not be steerable and you could lose control of the vehicle. The differential locks must therefore only be engaged when driving off-road. You may only engage the differential locks if the functions of the 4ETS and ESP® driving systems and the LOW RANGE off-road gear are insufficient. i The differential locks are only available in

the LOW RANGE off-road gear.

Activating the differential lock Important safety notes G WARNING When differential locks are engaged on a firm, high-grip surface, the vehicle's steerability is greatly impaired. In particular, engaging the differential locks when cornering could lead to you losing control of the vehicle. There is a risk of an accident. Disengage the differential locks immediately on firm, high-grip surfaces. G WARNING ABS, 4ETS, ESP® and BAS are deactivated while the differential locks are engaged. As a result, the wheels could lock when braking

and the braking distance is increased. There is a risk of an accident. Disengage the differential locks immediately on firm, high-grip surfaces.

! Only activate the differential locks when:

Ryou are driving at walking pace. Rthe driven wheels are not spinning. Ryou are not driving on a firm road surface.

Towing a trailer Notes on towing a trailer Important safety notes G 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.

204 Towing a trailer

G 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. G 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. G 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 (Y page 349).

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: Rthe permissible trailer drawbar noseweight Rthe permissible trailer load Rthe permissible rear axle load of the towing

vehicle

Rthe 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: Ris heavier Ris restricted in its acceleration and

gradient-climbing capability

Rhas an increased braking distance Ris affected more by strong crosswinds Rdemands more sensitive steering Rhas 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 RDo not exceed the legally prescribed

maximum speed for vehicle/trailer combinations in the relevant country. This lowers the risk of an accident.

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.

RIf 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.

i 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 (Y page 322).

You will find installation dimensions and loads in the technical data (Y page 358). 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 (Y page 358). However, the actual noseweight must not exceed the value given on the trailer tow hitch or trailer identification plates. The lowest weight applies. i 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 (Y page 322).

Please note that when towing a trailer, PARKTRONIC (Y page 194) and Blind Spot Assist (Y page 186) are only available with limitations, or not at all. i 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 height- adjustable drawbar.

Driving tips X On long and steep downhill gradients,

select shift range 1, 2 or 3 (Y page 150) in good time.

i This also applies if you have activated

cruise control or SPEEDTRONIC.

X If necessary, shift the transfer case to LOW

RANGE(Y page 199). 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. i 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.

Trailer with 7-pin connector General notes You can make a connection to the 13-pin socket on the ball coupling using an adapter or, if necessary, an adapter cable. Both can be obtained in a qualified specialist workshop.

Installing the adapter ! Make sure that there is enough slack in the cable for cornering so that the cable cannot become detached.

X Open the socket cover. X Insert the connector with lug : into groove ; on the socket and turn the connector clockwise to the stop.

X Make the cover engage. X If you are using an adapter cable, secure

the cable to the trailer with cable ties.

i When the socket is connected, the

ultrasonic backing up aid is deactivated.

Driving tips If the trailer swings from side to side: X Do not accelerate. X Do not counter-steer. X Brake if necessary. RMaintain a greater distance from the

vehicle in front than when driving without a trailer.

RAvoid braking abruptly. If possible, brake gently at first to allow the trailer to run on. Then, increase the braking force rapidly.

RThe 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 gradient- climbing capability, decrease with increasing altitude.

Trailer power supply ! You can connect accessories with a

maximum power consumption of 180 W to the permanent power supply. You must not charge a trailer battery using the power supply.

The trailer socket of your vehicle is equipped at the factory with a permanent power supply. The permanent power supply is supplied via trailer socket pin 9. A qualified specialist workshop can provide more information about installing the trailer electrics.
