2012 Mercedes-benz CLS Class Owners Manual

G WARNING ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentration too late or not at all. It is not a substitute for a well-rested and attentive driver. Fatigue may cause you to recognize hazardous situations too late, misjudge a situation or react more slowly. For this reason, make sure you feel rested before you begin driving and during your journey. Make sure that you take regular breaks in time, particularly on long journeys. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

ATTENTION ASSIST assesses your level of fatigue or lapses in concentration by taking the following criteria into account: Ryour personal driving style, e.g. steering

characteristics

Rdriving conditions, e.g. time, driving time The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the road condition is poor, e.g. if the

surface is uneven or if there are potholes

Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration

Rif you predominantly drive at speeds under

50 mph (80 km/h) or over 112 mph (180 km/h)

Rif you are currently operating or making a

call using COMAND

Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed

Warning and display messages in the multifunction display

X Activate ATTENTION ASSIST using the on-

board computer (Y page 207). Symbol : appears in the multifunction display.

If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun. You will then hear an intermittent warning tone twice, and the Attention Assist: Drowsiness detected message appears in the multifunction display. X If necessary, take a break. X Press a to confirm the message. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break and ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration, you will be warned again after 15 minutes at the earliest. ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if: Ryou switch off the engine. Ryou take off your seat belt and open the

driver's door, e.g. for a change of drivers or to take a break.

Night View Assist Plus Important safety notes In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. The Night View Assist Plus camera picks up the infrared light and displays a grayscale image in the COMAND display. The image displayed in COMAND corresponds to a road lit up by high-beam headlamps. This enables you to see the road's course and any obstacles in good time. If pedestrian recognition is activated, pedestrians recognized by the system are highlighted in the Night View Assist Plus display. G WARNING Night View Assist Plus is only an aid designed to assist driving. It is not a substitute for attentive driving. Do not rely solely on the Night View Assist Plus display. Continue to look through the windshield. You are responsible for safety and must drive in accordance with traffic conditions. You could otherwise put yourself and others in danger. The system may be impaired or unavailable if: Rthere is poor visibility, e.g. due to snow,

rain, fog or heavy spray.

Rthe windshield is dirty, fogged up or

covered, for instance by a sticker, in the vicinity of the camera.

Ryou are driving on bends, uphill gradients

or downhill gradients.

Light from the headlamps of oncoming vehicles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the high-beam headlamps because of oncoming traffic. G WARNING The Night View Assist Plus cannot record objects immediately in front of or next to the vehicle. When maneuvering, continue to look through the windshield. Make sure no

persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

i Infrared light is not visible to the human

eye and therefore does not glare. Night View Assist Plus can therefore remain switched on even if there is oncoming traffic.

when the vehicle is driving at speeds of at least 6 mph (10 km/h). This means that you do not have the full visual range while stationary and cannot check whether Night View Assist Plus is working.

Pedestrian recognition G WARNUNG Pedestrian recognition may be impaired or inoperative if: Rpedestrians are partially or entirely

obscured by objects, e.g. parked vehicles. Rthe silhouette of the pedestrian in the Night

View Assist Plus display is incomplete or interrupted, e.g. by powerful light reflections.

Rpedestrians do not contrast with the

surroundings.

Rpedestrians are not standing upright, for example, if they are sitting, crouching or lying down.

i Animals are not recognized by pedestrian

recognition.

Night View Assist Plus is able to recognize pedestrians by typical characteristics, e.g. a silhouette in the shape of a person. Pedestrian recognition is then switched on automatically if: RNight View Assist Plus is activated. Ryou are driving faster than 6 mph

(10 km/h).

Rthe surroundings are dark, e.g. when driving outside built-up areas without street lighting.

If pedestrian recognition is active, symbol ? appears. If pedestrians are recognized, they are framed = and thereby highlighted. If the pedestrian recognition system has brought a pedestrian to your attention, look through the windshield to evaluate the situation. The actual distance to objects and pedestrians cannot be gauged accurately by looking at a screen. It may be the case that objects are highlighted as well as pedestrians.

Fogged up or dirty windshield If the windshield in front of the camera is fogged up or dirty on the inside or outside, the Night View Assist Plus display is affected. G WARNING Please do not forget that your primary responsibility is to drive the vehicle. A driver's attention to the road must always be his/her primary focus when driving. For your safety and the safety of others, stop before trying to remove window fogging or cleaning the windshield in front of the Night View Assist Plus camera.

Lane Tracking package General information The Lane Tracking package consists of Blind Spot Assist (Y page 184) and Lane Keeping Assist (Y page 186).

Blind Spot Assist Important safety notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It begins to work at speeds of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to detected vehicles in the monitored area. If you then indicate a turn towards that side before changing lanes, you will also receive visual and audible collision warnings. The Blind Spot Assist monitoring system uses sensors in the rear bumper.

G WARNING Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehicles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traffic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow, rain or mist, for example. In this case, vehicles are detected late or not at all. 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.

i USA only:

This device has been approved by the FCC as a “Vehicular Radar System”. The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or

Driving systems

185

altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user’s authority to operate the equipment.

For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 211) and operational. Monitoring range of the sensors Blind Spot Assist monitors the area shown in the figure up to 10 ft (3 m) behind and immediately adjacent to your vehicle.

G WARNING 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. There is no display and no warning. 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 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.

Rwarnings may be interrupted when driving

alongside particularly long vehicles, for example trucks, for a prolonged time. 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 radar sensors must not be covered, for example by bicycle 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 specialist workshop, such as an authorized Mercedes- Benz Center. Blind Spot Assist may otherwise not work properly. Indicator and warning display

: Yellow indicator lamp/red warning lamp When Blind Spot Assist is activated, indicator lamp : lights up yellow in the exterior mirrors up to a vehicle speed of 20 mph

(30 km/h). When the vehicle speed exceeds 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is ready for use. When your speed exceeds approximately 20 mph (30 km/h), warning lamp : lights up red on the corresponding side whenever a vehicle is detected in the blind spot monitoring range. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you are passing another vehicle, the warning is emitted only if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if the reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G WARNING Blind Spot Assist is not active at speeds under approximately 20 mph (30 km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. 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.

Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the turn signal, a double warning tone sounds. 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. Switching on Blind Spot Assist X Make sure that the radar sensor system

(Y page 211) and Blind Spot Assist

(Y page 207) are activated in the on-board computer.

X Turn the SmartKey to position 2 in the

ignition lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5
seconds and then turn yellow.

Lane Keeping Assist Important safety notes Lane Keeping Assist monitors the area in front of your vehicle by means of a camera at the top of the windshield. Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally.

: Lane Keeping Assist camera If you have chosen the Display unit Speed-/odometer:(Y page 208) function in the on-board computer and select km as the unit of measurement, Active Lane Keeping Assist is active from speeds of 60 km/h.

Rseveral or no lane markings for a single lane

are present.

Rthe lane markings are worn away, dark or

covered up, e.g. by dirt or snow.

Rthe distance to the vehicle in front is too

small and the lane markings thus cannot be detected.

Rthe lane markings on the road are unclear,

e.g. near roadworks.

Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge.

Rthe road is narrow and winding. Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, 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.

A warning can be given when a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly.

The warning vibration occurs earlier if: Ryou approach the outer lane marking on a

bend.

Rthe road has very wide lanes, e.g. a

freeway.

Rthe system recognizes solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. Ryou cut the corner on a bend. No warning vibration occurs if: Ryou clearly and actively steer, brake or

accelerate.

Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, e.g.

ABS, BAS or ESP®.

Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.

Active Blind Spot Assist Important safety 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 detected vehicles in the monitored area. If you then indicate a turn towards that side before changing lanes, you will also receive visual and audible collision warnings. 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 speeds of approximately 20 mph (30 km/h). G WARNING Active Blind Spot Assist is only an aid, and may detect vehicles/obstacles incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to snow,

rain, fog or spray.

Rthe rear and/or front sensors are dirty. Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. It cannot detect vehicles that are overtaken at a small distance and then enter the blind spot area. Active Blind Spot Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, 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.

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 the lanes are narrow, the system may be unable to distinguish the neighboring lane from the one beyond it. For this reason, vehicles in the farther lane may be indicated, especially if the vehicles are driving in a staggered formation in different lanes. 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 sensor areas on the bumpers and the sensor cover in the radiator grill are free from dirt, ice and 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 specialist workshop, e.g. an authorized Mercedes-Benz Center. Active Blind Spot Assist may otherwise not work properly.

Lane-correcting brake application If you leave your lane under certain circumstances the vehicle will brake briefly on one side. This is meant to assist you in bringing the vehicle back to the original lane. This function is available in the range between 40 mph and 120 mph (60 km/h to 200 km/h). A lane-correcting brake application can only be made after driving over a solid, recognizable lane marking. Before this, a warning must be given by means of intermittent vibration in the steering wheel. In addition, a lane with lane markings on both sides must be recognized. The brake application also slightly reduces vehicle speed. If a lane-correcting brake application occurs, the following, for example, appears in the multifunction display:

i A further lane-correcting brake

application can only occur after your vehicle has returned to the original lane. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the lane-

correcting brake application is not sufficient to bring your vehicle back to the original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist does not detect road and traffic conditions. Always make sure that there is sufficient distance to the side for other traffic or obstacles. In rare cases, unclear markings or particular structures on the roadway can be recognized as solid lane markings. An inappropriate brake application, e.g. after intentionally driving over a solid lane marking, may be interrupted at any time by steering slightly in the opposite direction. Active Lane Keeping Assist cannot take weather conditions into account. You are responsible for the driving at appropriate speeds, braking in good time, and steering correctly.

this could damage the engine.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display The outside temperature display is in the multifunction display (Y page 198).

Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

Changes in the outside temperature are displayed after a short delay.

Speedometer with segments The segments in the speedometer indicate which speed range is available. Cruise control (Y page 155) activated: The segments light up from the stored speed to the maximum speed. DISTRONIC PLUS (Y page 157) activated: One or two segments in the set speed range light up. DISTRONIC PLUS detects a vehicle in front:

The segments between the speed of the vehicle in front and the stored speed light up.

Operating the on-board computer Overview The on-board computer is activated as soon as you turn the SmartKey to position 1 in the ignition lock. You can control the multifunction display and the settings in the on-board computer using the buttons on the multifunction steering wheel.
