The climate control is a 3-zone intelligent climate control system. Your vehicle interi- or is divided into 3 zones.

Warning!

When operating the climate control, the air that enters the passenger compartment through the air vents in the footwell can be very hot or very cold (depending on the set temperature). This may cause burns or frost- bite on unprotected skin in the immediate area of the air vents.

Always keep sufficient distance between un- protected parts of the body and the footwell air vents. If necessary, change the air flow using the air distribution controls (컄 page 218) to direct the air away from the footwell air vents.

Controls in detail 3-zone automatic climate control*

With the help of a sun sensor, the climate control determines the relation of the sun to the vehicle and automatically adjusts the inside temperature for every individual zone. The climate control is operational whenev- er the engine is running. It cools the vehi- cle’s interior according to the angle and intensity of the sun’s rays, the outside tem- perature and the selected temperature. You can operate the automatic climate control in either the automatic or manual mode.

219

Controls in detail 3-zone automatic climate control*

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters 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 218).

Warning!

Follow the recommended settings for heat- ing and cooling given on the following pag- es. Otherwise the windows could fog up, impairing visibility and endangering you and others.

Severe conditions (e.g. strong air pollu- tion) may require replacement of the fil- ter 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. Keep the air intake grille in front of the windshield free of snow and debris.

Air conditioning

The air conditioning is operational while the engine is running and cools the interior air to the temperature set by the operator. In addition the air conditioning dehumidi- fies the interior air at outside temperatures above than 41°F (5° C) and helps prevent window fogging.

Condensation may drip out from under- neath the vehicle. This is normal and not an indication of a malfunction.

Warning!

If you turn off the cooling function, the inte- rior air is not dried. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.

225

226

Activating Moist air can fog up the windows. You can dehumidify the air with the air condition- ing. 왘 Press button 2 again.

The indicator lamp on button 2 comes on.

The air conditioning system uses the refrig- erant R-134a. This refrigerant is free of CFCs which are harmful to the ozone layer.

If the air conditioning cannot be turned on again, this indicates that the air conditioning is losing refrigerant. The compressor has turned itself off. Have the air conditioning checked at the nearest authorized Mercedes-Benz Light Truck Center.

Residual heat and ventilation

With the engine switched off, it is possible to continue to heat or ventilate the interior for up to 30 minutes. This feature makes use of the residual heat produced by the engine.

How long the system will provide heat- ing depends on the coolant tempera- ture and the battery voltage. Regardless of the temperature and air volume set on the climate control panel an interior temperature is aimed at by 72°F (22°C) and the blower runs for the protection of the battery on low stage.

Cruise control

The cruise control automatically maintains the speed you set for your vehicle. Use of cruise control is recommended for driving at a constant speed for extended periods of time. You can set or resume cruise control at any speed above 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 on the left-hand side of the steering column (컄 page 22).

The cruise control should not be acti- vated during off-road driving.

Warning!

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

Only use the cruise control if the road, traffic, and weather conditions make it ad- visable to travel at a steady speed. 앫 The use of cruise control can be danger- ous on winding roads or in heavy traffic because conditions do not allow safe driving at a steady speed.

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

앫 Deactivate the cruise control when driv-

ing in fog.

The “Resume” function should only be oper- ated if the driver is fully aware of the previ- ously set speed and wishes to resume this particular preset speed.

Warning!

The cruise control brakes automatically so that the set speed is not exceeded. The brake pedal depresses when the cruise con- trol engages the brakes.

Keep driver’s foot area clear at all times, in- cluding the area under the brake pedal. Ob- jects stored in this area may impair pedal movement which could interfere with the braking ability of the cruise control system.

Do not place your foot under the brake pedal - your foot could become caught.

Keep in mind that the cruise control is a con- venience system designed to assist the driv- er during vehicle operation. The driver is and must always remain responsible for the ve- hicle’s speed and for safe brake operation.

Warning!

Warning!

The speed stored in memory should only be set again if prevailing road conditions per- mit. Possible acceleration or deceleration differences arising from returning to the pre- set speed could cause an accident and/or serious injury to you and others.

왘 Briefly pull the cruise control lever in di-

Downhill Speed Regulation is a convenience system designed to assist the driver during vehicle operation. The system must be set to be appropriate for the topographical and weather conditions encountered which can change quickly. The driver is and must remain at all times responsible for the vehi- cle speed and for safe brake operation.

Depending on the programmed speed (컄 page 176), actual vehicle speed and gra- dient, switching on the DSR while driving can cause the vehicle to slow down rapidly and you may hear a sound which is caused by the activation of the vehicle’s brake sys- tem through the DSR. Sudden and unex- pected decelaration can result in loss of vehicle control, causing an accident and/or serious personal injury to you and others. Do not switch on the DSR in a circumstance where rapid decelaration could result in a loss of vehicle control.

243

Controls in detail Driving systems

For more information, see “Off-road driv- ing” (컄 page 306). The DSR is an aid for driving downhill. DSR regulates your vehicle’s speed when driv- ing downhill to the value set in the control system (컄 page 176). The steeper the downhill gradient is, the greater the brake application. On flat road surfaces, DSR brakes only slightly or not at all. DSR regulates the vehicle’s speed in auto- matic transmission positions D, or R. You can drive slower or faster than the set speed at any time by braking the vehicle or depressing the accelerator pedal.

244

Whenever the DSR is switched on, the programmed default speed will be used. That value can be changed through the multifunction display. The next time the DSR is switched on, it will use that newly programmed default speed. Depending on the road surface and lev- el of downhill grade, the DSR may not be able to maintain the set speed. To maintain the set speed, apply the brakes if necessary.

Whenever DSR is switched on, DSR will use the programmed default speed to regulate the vehicle’s speed. The de- fault speed programmed at the factory is 4 mph (Canada: 6 km/h). The de- fault speed can be reprogrammed us- ing the control system (컄 page 176). The next time DSR is switched on, DSR will use the newly programmed default speed to regulate the vehicle’s speed. Once DSR is switched on, you can ad- just the set speed using the cruise con- trol lever (컄 page 238). Keep in mind that adjusting the set speed using the cruise control lever with DSR switched on will not change the programmed de- fault speed. If DSR is switched off and then switched on again, DSR will use the programmed default speed.

Switching the Downhill Speed Regulation on/off The switch is located in the lower part of the center console.

Switch for DSR 1 DSR on/off 2 Indicator lamp

Warning!

If the accelerator pedal is depressed while the Downhill Speed Regulation is activated, the vehicle can drive faster than the pro- grammed set speed. You should therefore drive downhill with particular caution as it could otherwise lead to an accident and/or serious injury to you or others. Keep in mind that as soon as you remove the foot from the accelerator pedal with the DSR switched on, the DSR will start regulating the vehicle’s speed including use of brakes where re- quired. Depending on the programmed set speed, actual vehicle speed and gradient, the DSR can cause the vehicle to slow down rapidly. Sudden and unexpected decelara- tion can result in loss of vehicle control, causing an accident and/or serious person- al injury to you and others.

The vehicle automatically regulates its ride height based on the set vehicle height and the current speed: 앫 The ride height of the vehicle is re-

duced with increasing vehicle speed.

250

앫 The ride height of the vehicle changes from the high-speed level back to the normal highway level as the vehicle speed is decreased.

The parked vehicle begins adjusting to the set vehicle level as soon the doors and tail- gate are 앫 unlocked or 앫 opened. In order to operate the vehicle level control switch (컄 page 252), however, the engine must be running. For safety reasons, the vehicle lowers only when all doors are closed. The lowering procedure is interrupted as soon as a door is opened. The lowering will resume as soon as all doors are closed.

Warning!

Please be aware that by raising the vehicle level, the center of gravity also rises. There- fore, always ensure that the vehicle level is as low as possible. With higher ride height the ESP® may activate earlier in certain situations.

Warning!

Make sure that no one is near the wheel housing or under the vehicle when you lower the vehicle while it is standing still. Limbs could become wedged into or under the ve- hicle.

For safety reasons, the vehicle can only be lowered with the doors closed. Lowering is interrupted if a door is opened and will con- tinue after the door is closed again.

i The activation thresholds are defined by the set suspension tuning (컄 page 249).

Parktronic* system (Parking assist)

Warning!

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 rests 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.

The operational function of the Parktronic system can be affected by dirty sensors, es- pecially at times of snow and ice. See “Cleaning the Parktronic system sensors” (컄 page 377). Interference caused by other ultrasonic sig- nals (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.

Warning!

Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

The Parktronic system is an electronic parking aid and designed to assist the driver during parking maneuvers. It visually and audibly indicates the relative distance between the vehicle and an obstacle. The Parktronic system is automatically activated when you switch on the ignition, release the parking brake, and set the automatic transmission to D, R, or N. The Parktronic system deactivates at speeds over approximately 11 mph (18 km/h). At lower speeds the Parktronic system turns on again. The Parktronic system also deactivates when you set the automatic transmission to P or depress the parking brake pedal.

The Parktronic system monitors the sur- roundings of your vehicle with six sensors in the front bumper and four sensors in the rear bumper.

1 Sensors in the front bumper

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 damaging the sensors, see “Cleaning the Parktronic* system sensors” (컄 page 377).
