Version: 2.11.8.1G Warning! The Parking Guidance is only an aid and may display parking spaces that are not suitable for parking such as Rno-parking zones Rparking space with unsuitable road/ground
surface
Rdriveways Rentrances/exits The Parking Guidance scans for and measures potential parking spaces when driving past. Subsequent changes to the parking space are not taken into account. This may be the case if the position of the vehicle parked in front or behind the space changes or obstacles in the parking space are moved. The Parking Guidance does not relieve you of the responsibility to pay attention. If you only rely on the Parking Guidance, you may cause an accident and injure yourself and others. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering. G Warning! The system cannot detect objects located above the area that the sensors scan. These objects, e.g. protruding load, overhang, or truck tail lifts, will be ignored when computing the parking procedure. The Parking Guidance might therefore provide untimely steering instructions. This could cause a collision. Thus, do not use the Parking Guidance in such situations. G Warning! Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

curves
Ron the same level as the street, i.e. not on
sidewalks, for example.
Parking instructions: ROn narrow streets, drive by the parking
space as close as possible.
RParking spaces that are dirty, overgrown or
located in front of trailers may not be detected correctly.
RSnowfall or heavy rain may cause imprecise
measurement of the parking space. RAlso observe the Parktronic system
warning indicator (Y page 167) while the Parking Guidance is active.
RYou may not use the Parking Guidance
when transporting cargo that protrudes the vehicle.
RDo not use the Parking Guidance when
driving with snow chains or when a spare wheel is mounted.
RHow well your vehicle will be parked after
completion of the Parking Guidance depends on the position and shape of the vehicles parked in front of and behind the parking space as well as the conditions of the immediate surroundings. In certain cases, the Parking Guidance may guide you too far into the parking space or not far enough. If this is the case, cancel the parking procedure with the Parking Guidance and correct the vehicle position yourself.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such

Blind Spot Assist The Blind Spot Assist uses radar sensors to monitor the area on both sides of your vehicle. It will assist you when you change lanes driving at speeds of above 20 mph (30 km/h). A red warning lamp will come on in the exterior rear view mirror as soon as another vehicle is detected. If you then activate the corresponding turn signals to change lanes, the red warning lamp flashes and warning sounds (collision warning). The Blind Spot Assist operates using sensors in the rear bumper. G Warning! The Blind Spot Assist is only a driving aid and may not detect all vehicles. The Blind Spot Assist may not be able to detect narrow vehicles such as motorcycles or bicycles, or it may not detect them until it is too late. The monitoring function may be impaired if your sensors are dirty, subject to heavy spray, or if visibility is poor due to e.g. snow, rain, or fog. This can result in vehicles not being detected or being detected too late. The Blind Spot Assist cannot detect road, traffic and weather conditions. It is the driver’s responsibility at all times to be attentive to road, weather and traffic conditions and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Failure to do so could result in recognizing dangers too late, possibly resulting in an accident and serious injury to yourself and others. In order for the Blind Spot Assist to function, the radar sensors must be switched on and operational. When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 144). Canadian

G Warning! The Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles approaching and passing at speeds that exceed the speed of your vehicle significantly will not be detected. There will be no warning display and no audible warning. When driving in a very wide lane, the sensors may not be able to cover the entire width of the neighboring lane. Vehicles driving on the outside of the neighboring lane may not be detected. It is the driver’s responsibility at all times to be attentive to road, weather and traffic conditions and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Failure to do so could result in recognizing dangers too late, possibly resulting in an accident and serious injury to yourself and others. When driving in a very narrow lane, the sensors may detect and display vehicles in the second lane over. This will be the case if there are vehicles driving on the inside edge of their lane. The system may issue causeless warnings in the area of guardrails or similar structural boundaries. The two Blind Spot Assist sensors are built into the rear bumper. Make sure that the area
2009-07-17T09:14:21+02:00 - Seite 176

Lane Keeping Assist The Lane Keeping Assist supports you at a vehicle speed of above 40 mph when you have set the display unit to miles in the Display Unit Speed-/Odometer: menu in the control system (Y page 141). When you have set the display unit to km, the system supports you at a vehicle speed of above 60 km/h. When the Lane Keeping Assist detects lane markings, the system is designed to alert you in case you leave your lane unintentionally. A warning is usually issued when a front wheel is on the lane marking. An interval vibration in the steering wheel that lasts for up to 1.5 seconds will then alert you.
The Lane Keeping Assist monitors the area in front of your vehicle via camera :. The system can distinguish various conditions in order to alert you early enough and to avoid unnecessary warnings when crossing lane markings. The warning is issued sooner when Rcutting a curve on the outside of the turn Rdriving on very wide lanes such as highway
lanes
Rthe system recognizes dividing lines
because crossing them is often crucial due to soft shoulders or guardrails behind for example
The warning is issued later however when Rdriving on narrow lanes Rcutting a curve on the inside of the turn

Notes on climate control system The climate control system is operational whenever the engine is running. You can
operate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature.

It can only function optimally when you are driving with the windows, the tilt/sliding sunroof or tilt/sliding panel closed. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Center. The air conditioning will not engage (no cooling) if the A/C mode (Y page 185) is deactivated. G 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.
X Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window. i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer opening feature” (Y page 107). The climate control will then adjust the interior temperature to the set value much faster.
Deactivating the climate control system G Warning! When the climate control system is deactivated, the outside air supply and circulation are also deactivated. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others.

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 dehumidifies the interior air and helps prevent window fogging. G Warning! If you deactivate the air conditioning, the vehicle will not be cooled when weather conditions are warm. The windows can fog up more quickly. Window fogging may impair visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and not an indication of a malfunction.

Adjusting air vents G Warning! 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 to unprotected skin in the immediate area of the air vents.
Climate control system 187
Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution adjustment to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin. For best possible performance of the climate control: X Keep the air intake grille in front of the
windshield free of snow, leaves, sticks, and any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from obstruction.
i For draft-free ventilation, move the
adjustable center and side air vents to the middle position.
