DISTRONIC Plus is switched on.

or 왘 Pull DISTRONIC Plus lever briefly in di-

rection of arrow 4 to call up speed last set (컄 page 423). DISTRONIC Plus is switched on.

왘 Take your foot off the accelerator ped-

al. Your vehicle adapts its speed to the ve- hicle ahead, observing the set speed as a maximum value.

i Under 20 mph (30 km/h), you can only switch on DISTRONIC Plus if the vehicle ahead of you has been detected and is shown on the mul- tifunction display. If you no longer see the vehi- cle in front of you on the multifunction display and if it is no longer detected because it has changed lanes, for example, DISTRONIC Plus switches off and you will hear a signal.

i If you do not completely lift your foot off the accelerator pedal, the message “DISTRONIC PLUS override” appears on the mul- tifunction display. The distance to a slower-driv- ing vehicle will not be set. You will drive at the speed you dictate by pressing the accelerator pedal.

i If DISTRONIC Plus is switched off, PRE-SAFE® Brake* (컄 page 73) will warn of an impending collision if this function has been activated with the instrument cluster control system (컄 page 268).

Starting off When the vehicle in front of you starts off: 왘 Remove your foot from the brake

pedal.

왘 Pull DISTRONIC Plus lever briefly in di-

rection of arrow 4.

or 왘 Briefly step on the accelerator pedal. Your vehicle starts off and adapts its speed to the vehicle in front of you.

Switching on when approaching a stationary vehicle If the vehicle in front of you is stationary, you can only switch on DISTRONIC Plus if your vehicle is also at a standstill. 왘 Tap DISTRONIC Plus lever up 1 or down 2 until desired speed is set. DISTRONIC Plus is switched on.

or 왘 Pull DISTRONIC Plus lever briefly in di-

rection of arrow 4 to call up speed last set (컄 page 423). DISTRONIC Plus is switched on.

i It is helpful to switch on the DISTRONIC Plus display in the instrument cluster (컄 page 416) since you can only switch on DISTRONIC Plus un- der a speed of 20 mph (30 km/h) when a vehicle has been detected in front of you.

i You can adjust the set speed using the DISTRONIC Plus lever and the target distance using the distance setting switch on the DISTRONIC Plus lever (컄 page 425).

Controls in detail Driving systems

Driving If no vehicle is driving ahead of you, DISTRONIC Plus functions like the cruise control (컄 page 405). When DISTRONIC Plus detects that the ve- hicle in front of you is driving more slowly, it brakes the vehicle in order to keep the distance specified by you. When DISTRONIC Plus detects that the ve- hicle in front of you is driving faster, the ve- hicle accelerates up to the set speed.

Warning!

When you step on the brake pedal, you switch off DISTRONIC Plus except when the vehicle is at a standstill. DISTRONIC Plus will no longer brake your vehicle. You are always responsible for maintaining a distance from other vehicles, observing road speeds and braking well in advance.

419

Warning!

Never get out of the vehicle while DISTRONIC Plus is switched on!

DISTRONIC Plus must never be operated or switched off by passengers or from outside the vehicle.

DISTRONIC Plus is not a substitute for the electronic parking brake and may not be used for parking.

When you get out of the vehicle or switch off the engine, deactivate DISTRONIC Plus and secure the vehicle from rolling away by en- gaging the electronic parking brake.

When DISTRONIC Plus detects that the ve- hicle in front of you is stopping, the vehicle brakes until it also stops. Once DISTRONIC Plus has stopped your vehicle and it is at a standstill, it remains stationary; the brake pedal does not need to be depressed.

i After a short while, your vehicle is secured in place by the electronic parking brake so that the operating brake can be relieved of load.

i Depending on the following distance set us- ing the distance setting switch on the DISTRON- IC Plus lever, your vehicle will stop approximately 13.1 ft away from the vehicle in front of you.

! Setting the automatic transmission to N while driving cancels the DISTRONIC Plus. How- ever, the automatic transmission should not be set to N while driving except to coast when the vehicle is in danger of skidding (e.g. on icy roads).

i Depressing the accelerator pedal does not deactivate DISTRONIC Plus. After brief accelera- tion (e.g. for passing), DISTRONIC Plus will re- sume to the last set speed.

If the vehicle has been stopped by DISTRONIC Plus and a malfunction occurs in the system, the message “Brake immedi- ately” will appear on the multifunction dis- play. Step on the brake immediately to prevent the vehicle from rolling. DISTRONIC Plus is then switched off and the message disappears.

Warning!

DISTRONIC Plus switches off and releases the brakes when the vehicle decelerates be- low the minimum speed of 20 mph (30 km/h) by operation of the system un- less DISTRONIC Plus detects a vehicle di- rectly ahead of you. At that time the driver must apply the brakes in order to reduce ve- hicle speed further or bring it to a stop.

Setting the following distance in DISTRONIC Plus You can set the specified following dis- tance for DISTRONIC Plus by varying the time setting between 1.0 and 2.0 seconds. Using this time setting and the current speed of your vehicle, DISTRONIC Plus cal- culates and sets the required following dis- tance to the preceding vehicle. The set distance will be shown in the multifunction display.

Warning!

It is up to the driver to exercise discretion to select the appropriate setting given road conditions, traffic, driver’s preferred driving style and applicable laws and driving recom- mendations for safe following distance.

The distance setting switch for the target distance is located on the DISTRONIC Plus lever.

Controls in detail Driving systems

Driving with DISTRONIC Plus This section describes a number of driving situations where special precaution is re- quired on the part of the driver. Be pre- pared to brake in such situations. Braking will deactivate the DISTRONIC Plus sys- tem.

Warning!

DISTRONIC Plus works to maintain the speed selected by the driver unless a mov- ing obstacle proceeding directly ahead of it in the same travel direction is detected (e.g. following another vehicle ahead of you at your set distance).

This means that: 앫 Your vehicle can pass another vehicle

after you change lanes.

앫 While in a sharp turn or if the vehicle in front is in a sharp turn, DISTRONIC Plus could lose sight of a vehicle traveling in front of it, then your vehicle could accel- erate to the previously selected speed.

DISTRONIC Plus regulates only the distance between your vehicle and those directly ahead of it. It may not register stationary ob- jects in the road, e.g.: 앫 a stopped vehicle in a traffic jam 앫 a disabled vehicle 앫 an oncoming vehicle The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle.

Warning!

DISTRONIC Plus should not be used in snowy or icy road conditions.

The most likely cause for a malfunctioning system is a dirty sensor (located behind the hood grille), especially at times of snow and ice or heavy rain. In such a case, DISTRONIC Plus will switch off, and the message:

“DISTRONIC PLUS currently unavailable See Oper. Manual” appears in the multifunction display. For cleaning and care of the DISTRONIC Plus sensor, see “Cleaning the DISTRONIC Plus*/ PRE-SAFE® Brake* sys- tem sensors (USA only)”(컄 page 558).

i If the message: “DISTRONIC PLUS currently unavailable See Oper. Manual” disappears during driving and the last speed stored flashes for approximately 5 seconds, the dirt (e.g. slush) has dissolved; DISTRONIC Plus is available again.

Another cause might be that the radar sen- sors have been manually switched off in the instrument cluster control system. Please verify that the radar sensors are switched on (컄 page 272).

426

Turns and bends

Offset driving

Lane changing

Controls in detail Driving systems

In turns or bends, DISTRONIC Plus may not detect a moving vehicle in front, or it may detect one too soon. This may cause your vehicle to brake late or unexpectedly.

A vehicle traveling in your lane but offset from your direct line of travel may not be detected by DISTRONIC Plus. There will be insufficient distance to the vehicle ahead.

DISTRONIC Plus has not yet detected the vehicle changing lanes. There will be insuf- ficient distance to the lane-changing vehi- cle.

427

Controls in detail Driving systems

Narrow vehicles

Obstacles and stationary vehicles

Cross-traffic

Because of their narrow profile, the vehi- cles traveling near the outer edge of the lane have not yet been detected by DISTRONIC Plus. There will be insufficient distance to the vehicles ahead.

DISTRONIC Plus does not brake for obsta- cles or stationary vehicles. If, for example, the vehicle detected in front of you chang- es lanes to bypass an obstacle or station- ary vehicle in front of it, DISTRONIC Plus will not brake for the obstacle or stationary vehicle.

DISTRONIC Plus may inadvertently detect crossing vehicles. If you switch on DIS- TRONIC Plus, for example, at a traffic light with cross-traffic, the vehicle may sudden- ly start to drive off.

428

Active Body Control (ABC)

The ABC system is an active, comput- er-controlled system that hydraulically ad- justs the suspension at all four wheels in response to various driving situations. It automatically selects the optimum suspen- sion tuning and ride height for your vehicle.

Vehicle level control

Warning!

To help avoid personal injury, keep hands and feet away from wheel housing area, and stay away from under the vehicle when lowering the vehicle chassis.

Your vehicle automatically adjusts its ride height to: 앫 increase vehicle safety 앫 reduce fuel consumption The vehicle chassis ride height is raised or lowered according to the selected level setting and to the vehicle speed: 앫 With increasing speed, ride height is re-

duced by up to approximately 0.4 in (10 mm).

앫 With decreasing speed, the ride height is again raised to the selected vehicle level.

i These height adjustments are so small that you may not notice any change.

Controls in detail Driving systems

The following vehicle level settings can be selected when the vehicle is stationary:

Level Normal

Parktronic system*

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 remains with the driver.

Warning!

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

! Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated cross- bars 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, espe- cially at times of snow and ice. Make sure that the area on the bumpers around the sensors is free of dirt, ice and/or slush, otherwise the Parktronic system may not function properly, see “Cleaning the Parktronic* system sensors” (컄 page 559).

i 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.

The Parktronic system is an electronic parking aid with ultrasonic sensors that helps you while parking. It visually and audibly indicates the relative distance between the vehicle and an ob- stacle. The Parktronic system is automatically ac- tivated when you switch on the ignition, re- lease the electronic parking brake or start the engine and engage gear D, R or N.

Controls in detail Driving systems

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 secure the vehicle in place with the electronic parking brake and switch off the engine. The Parktronic system monitors the sur- roundings of your vehicle with six sensors in the front bumper and four sensors in the rear bumper.

In this case, you should not use the guide lines to judge dis- tance. The use of the guide lines to judge distance increases the risk of impacting the objects.

Warning!

The Dynamic Rear View Monitor is a supple- ment system. It is not intended to, nor does it replace, the need for extreme care. The re- sponsibility during parking and other driving maneuvers always remains with the driver.

The Dynamic Rear View Monitor may show obstacles with a distorted perspective, in- correctly or not at all.

440

Special attention must be paid to objects outside of the camera’s field of view such as those located very close to or below the rear bumper, or above the recessed grip of the luggage compartment lid. Such objects may not be detected by the system and can dam- age the vehicle.

The Dynamic Rear View Monitor does not warn you about impending collisions with objects. The driver is always responsible for safety and must continue to pay attention to the immediate surroundings while parking or maneuvering the vehicle. This applies not only to the area behind the vehicle, but also to the area in front of and to the sides of the vehicle. Failure to do so could result in injury to persons and/or damage to the vehicle or other property. We also recommend that the driver use the Parktronic system* or Park Assist* when parking or maneuvering the vehicle.

Warning!

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

Warning!

The Dynamic Rear View Monitor may not function if: 앫 the trunk lid is not completely closed 앫 it is raining or snowing heavily, or if

there is thick fog 앫 in a very dark area 앫 the camera is exposed to very strong

white light (white stripes may appear on the COMAND display)

앫 the surrounding area is lit with fluores-

cent light (the COMAND display can flicker)

앫 outside temperatures are very high (lens

condensation)

앫 there is a sudden change in tempera-

ture, for example when you drive out of the cold into a heated garage in winter (lens condensation)

앫 the camera lens is dirty or covered, see

“Cleaning the Dynamic Rear View Monitor lens*” (컄 page 560)

앫 the rear of your vehicle is damaged. In this case, have the position and setting of the camera checked by a qualified technician. Contact an authorized Mercedes-Benz Center.

Do not use the Dynamic Rear View Monitor if the roads are icy, slippery or covered with snow. The vehicle could slip causing the ac- tual vehicle position to deviate from the one shown on the COMAND display.

This may cause injury to you or others, or damage the vehicle or objects.

Mounting tires/rims of other specification than the original equipment tires/rims may impair the function of the Dynamic Rear View Monitor. Contact an authorized Mercedes-Benz Center.

Warning!

Use of Dynamic Rear View Monitor can be dangerous if you are color-blind or have im- paired color vision.

Only use Dynamic Rear View Monitor if you can see and distinguish all colored guide lines shown by Dynamic Rear View Monitor on the COMAND display.

Warning!

Please note that objects which do not touch the ground, such as the bumper of a vehicle parked behind you, a trailer hitch, or the back of a truck, may appear to be further away than they actually are. In this case, you should not use the guide lines to judge dis- tance as the use of the guide lines to judge distance increases the risk of impacting the objects.

Even when the object you approach is di- rectly on the ground (and nothing on the ob- ject extends above the ground beyond the object’s contours directly touching the ground) and no objects that do not touch the ground, such as the bumper of a vehicle parked behind you, a trailer hitch, or the back of a truck are in the path, do not ap- proach the object on the ground any closer than red guide line 4.

Night View Assist*

Warning!

Night View Assist is only an aid to support you while driving and cannot substitute your careful attention. Do not rely on the display of the Night View Assist; instead, continue to look through the windshield. You are al- ways responsible for safety and must drive in accordance with traffic conditions. Other- wise, you could endanger yourself and oth- ers.

If it is foggy, raining or snowing, the clarity of the Night View Assist image on the multi- function display may be diminished.

Night View Assist illuminates the road with infrared light in addition to the normal headlamps. A camera at the top of the windshield mea- sures the infrared light and shows a black-and-white image on the multifunc- tion display.

446

The image on the multifunction display cor- responds to a road lit up by high-beam headlamps.

Warning!

Night View Assist cannot record objects im- mediately in front of or next to the vehicle. When maneuvering, continue to look through the windshield. Make sure no per- sons or animals are in the area in which you are maneuvering. You could otherwise in- jure them.

The Night View Assist image on the multi- function display is not impaired 앫 by the headlamps of approaching vehi-

cles

앫 if you cannot switch on the high beams

due to oncoming traffic

As a result, you can better follow the course of the road and detect obstacles earlier on.

i Infrared light is invisible to the human eye and can therefore remain permanently switched on without blinding oncoming traffic.

The camera is at the top of the windshield.

1 Night View Assist camera

Switching on or off You can only switch on the Night View As- sist if 앫 the SmartKey in the starter switch is

왘 Press button 1 up or down.

The Night View Assist image appears on the multifunction display.

i The infrared headlamps only come on above a speed of approximately 9 mph (15 km/h). Therefore, when you are at a standstill, you do not have a complete view and cannot check the function of the Night View Assist.

Image on multifunction display When you switch on Night View Assist, the image for the speed gauge changes on the multifunction display. The speed gauge is shown as a bar on the lower edge of the multifunction display. The line for main menus is no longer available. If you would like to change a setting using the steering wheel buttons, you must first switch off Night View Assist.

Warning!

When operating the automatic climate con- trol, the air that enters the passenger com- partment through the air vents can be very hot or very cold (depending on the set tem- perature). This may cause burns or frostbite to unprotected skin in the immediate area of the air vents.

Always keep sufficient distance between un- protected parts of the body and the air vents. If necessary, use the air distribution adjustment (컄 page 246) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

You can operate the climate control system in ei- ther the automatic or manual mode. The system cools or heats the interior depend- ing on the selected interior temperature and the current outside temperature. It can only function optimally when you are driving with the windows and the tilt/slid- ing sunroof closed. It is possible to completely deactivate the climate control system (컄 page 455).

454

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system.

Warning!

Follow the recommended settings for heat- ing and cooling given on the following pages and in the “COMAND automatic climate control” section (컄 page 244). Otherwise the windows could fog up, impairing visibili- ty and endangering you and others.

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 376). The automatic climate con- trol 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, leaves, sticks, and any other debris.
