i Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled interval. A clogged filter will reduce the air volume to the interior. If the vehicle interior is hot, ventilate the interior before driving off, see “Summer opening fea- ture” (컄 page 193). The climate control will then adjust the interior temperature to the set value much faster. Keep the air intake grille in front of the wind- shield free of snow and debris.


Controls in detail Climate control


The climate control is operational when- ever the engine is running. You can oper- ate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature and the current outside temperature.


Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 189).


Warning!


Warning!


Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others.


When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite on unpro- tected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distri- bution control (컄 page 186) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Cruise control


The cruise control automatically maintains the speed you set for your vehicle. The use of the cruise control is recom- mended for driving at a constant speed for extended periods of time. You can set or resume the cruise control at any speed over 20 mph (30 km/h). The cruise control function is operated by means of the cruise control lever. The cruise control lever is the uppermost lever found on the left-hand side of the steering column (컄 page 24).


i The cruise control should not be activated during-off road driving.


Controls in detail Driving systems


Warning!


The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle’s speed and for safe brake operation.


Only use the cruise control if the road, traffic and weather conditions make it advisable to travel at a steady speed. 앫 The use of the cruise control can be


dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a steady speed.


앫 The use of the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control.


앫 Deactivate the cruise control when


driving in fog.


The “Resume” function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed.

Interference caused by other ultrasonic signals (e.g. working jackhammers, car wash, or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration.


The Rear Parking Assist system is an electronic aid designed to assist the driver during parking maneuvers. It visually and audibly indicates the relative distance between the rear of the vehicle and an obstacle. The Rear Parking Assist system is automatically activated when you 앫 switch on the ignition

Rear Parking Assist


Warning!


Rear Parking Assist (rear Parktronic) is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always remains with the driver.


Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or road curbs). Such objects may not be detected by the system and can damage the vehicle.


200


The Rear Parking Assist system monitors the rear surrounding of your vehicle with four sensors in the rear bumper.


1 Sensors


Range of the sensors To function properly, the sensors must be free of dirt, ice, snow, and slush. Clean the sensors regularly, being careful not to scratch or damage the sensors, see “Cleaning the Rear Parking Assist sensors” (컄 page 318).


! During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. planters or trailer hitches). The Rear Parking Assist system will not detect such objects at close range and damage to your vehicle or the object may result. Ultrasonic signals from outside sources (e.g. working jackhammers, car wash, or the air brakes of trucks) may impair the operation of the Rear Parking Assist system.

If the system detects an obstacle in this range, all the distance segments in the warning indicator (컄 page 202) illuminate and you hear a warning signal. If the obstacle is closer than the minimum dis- tance, the actual distance may no longer be indicated by the system.


202


Warning indicator Visual signals indicate to the driver the relative distance between the sensors and an obstacle. The warning indicator is located next to the tailgate.


Warning indicator 1 Distance segments 2 Readiness indicator


The warning indicator is divided into four yellow, and two red distance segments 1. The Rear Parking Assist system is ready when you hear a signal and the readiness indicator 2 is illuminated. As your vehicle approaches an object, one or more distance segments will illuminate, depending on the distance. When the sixth distance segment illuminates, you have reached the minimum distance. An intermittent acoustic warning will sound when the fourth yellow distance segment illuminates. This signal quickens with each additional distance segment illuminated. When all distance segments illuminate, the acoustic warning becomes a constant signal. The signal is canceled when the gear selector lever is moved to drive position D or park position P.


Rear Parking Assist system malfunction If no distance segments illuminate and no acoustic warning sounds, there is a mal- function in the Rear Parking Assist system. 왘 Have the Rear Parking Assist system


checked at an authorized Mercedes-Benz Light Truck Center as soon as possible.


Rear view camera


Warning!


The rear view camera is only an aid and may display obstacles from a distorted perspec- tive or inaccurately, or may not display ob- stacles at all. The rear view camera does not relieve you of the responsibility to be cau- tious, take care and pay careful attention. The rear view camera may not show objects which are 앫 very close to the rear bumper 앫 under the rear bumper 앫 under the spare wheel 앫 nearby behind the spare wheel You are responsible for safety at all times and must continue to pay attention to the immediate surroundings when parking and maneuvering. This includes the area behind, in front of and beside the vehicle. Otherwise you could endanger yourself or others.

This vehicle is not intended to carry items on its roof. Thus roof rails and any roof-mounted devices must not be used.


Warning!


To expand the cargo compartment, you can fold forward the left and right section 앫 of the rear seat backrest 앫 of the rear seat bench separately.


Do not load items on the roof. It may cause instability during some maneuvers which could result in an accident.


Warning!


Warning!


Failure to assure that seat benches and seat backrests are locked into place could result in an increased chance of injury in an acci- dent.


Never place hands under seat or near any moving parts while a seat is being adjusted.


Always lock seat backrest in its upright position when rear seat bench is occupied by passengers, or cargo is being carried behind the rear seat bench.


To help avoid personal injury from smaller objects being thrown around in the occu- pant compartment during a collision or sudden maneuver, always use partition net* when transporting cargo (컄 page 210). Always use the cargo tie down rings (컄 page 209).


For safety reasons, the rear seat bench must only be adjusted when the vehicle is stationary.


Never drive vehicle with the tailgate open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in uncon- sciousness and death.


! Before folding the rear seat backrest and the rear seat bench forward, be sure that all containers in the rear cup holder are removed.

Loading instructions


Warning!


Always fasten items being carried as securely as possible using cargo tie-down rings and fastening materials appropriate for the weight and size of the load.


In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.


To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Put luggage or cargo in the cargo compartment if possible. Do not pile luggage or cargo higher than the seat backrests.


Never drive vehicle with the tailgate open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in uncon- sciousness and death.


208


Load distribution


The gross vehicle weight which is the weight of the vehicle including fuel, tools, spare wheel, installed accessories, pas- sengers and luggage/cargo must never exceed the load limit and Gross Vehicle Weight Rating (GVWR) for your vehicle as specified on the certification label located on the driver’s door B-pillar (컄 page 412). In addition, the load must be distributed in such a way so that the weight on each axle never exceeds the Gross Axle Weight Rating (GAWR) for the front and rear axle. The GVWR and GAWR for your vehicle are indicated on the certification label which can be found on the driver’s door B-pillar (컄 page 412). For more information, see “Tire and Load- ing Information” (컄 page 281).


The handling characteristics of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle according to the illustra- tions shown, with the heaviest items being placed towards the front of the vehicle. Please pay attention to and comply with the following instructions when loading the vehicle and transporting cargo: 앫 Always place items being carried


against front or rear seat backrests, and fasten them as securely as possible.


앫 The heaviest portion of the cargo


should always be kept as low as possi- ble against front or rear seat backrests.


앫 Always pad off sharp edges.


For additional safety when transporting cargo while the rear seats are unoccupied, fasten the outer seat belts crosswise into the opposite side buckles.


i The cargo compartment is the preferred place to carry objects. The expanded cargo com- partment (컄 page 206) should only be used for items which do not fit in the cargo compartment alone.
