Possible causes/consequences and M Solutions PARKTRONIC has malfunctioned and has switched off. X If problems persist, have PARKTRONIC checked at a qualified
specialist workshop.
The PARKTRONIC sensors are dirty or there is interference. X Clean the PARKTRONIC sensors (Y page 284). X Switch the ignition back on. The problem may be caused by an external source of radio or ultrasound waves. X See if PARKTRONIC functions in a different location.
Parking Guidance Important safety notes Parking Guidance is an electronic parking aid with ultrasound. Ultrasound is used to measure the road on both sides of the vehicle. A suitable parking space is indicated by the parking symbol. You receive steering instructions when parking. You may also use PARKTRONIC (Y page 178). G WARNING Parking Guidance is merely an aid and may display parking spaces that are not suitable for parking, for example: Rno-parking areas Rparking spaces with unsuitable surfaces
(road surface)
Rdriveways Rentrances and exits Parking Guidance detects and measures potential parking spaces while driving past. Changes to the parking space after this point are not taken into account, for example if the vehicle in front of or behind the parking space changes position or objects in the parking space are moved. Even when using Parking Guidance, you are still responsible for driving carefully. If you rely on Parking Guidance alone, you could cause an accident and injure yourself and others. Safety always remains your responsibility and you must continue paying careful attention to your immediate surroundings when parking and maneuvering.
182 Driving systems
G WARNING Objects located above the height range of Parking Guidance will not be detected when the parking space is measured. These objects are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. Under some circumstances, Parking Guidance might therefore issue steering instructions too soon. This may lead to a collision. For this reason, you should avoid using Parking Guidance in such situations. G WARNING Make sure that no persons or animals are in the maneuvering range. Otherwise, they could be injured.
! Pay particular attention to low objects or
objects with flat surfaces, such as trailer drawbars, posts, cross beams and curbs. These types of objects cannot be detected by Parking Guidance and may damage the vehicle.
When PARKTRONIC is deactivated, Parking Guidance is also unavailable. Use Parking Guidance for parking spaces: Rthat are parallel to the direction of travel Rthat are on straight roads, not bends Rthat are on the same level as the road, i.e. not on the pavement, for example. Parking Guidance may not detect flat curbs
Parking tips: Ron narrow roads, drive past the parking
space as close as possible.
Rparking spaces that are littered, overgrown
or partially occupied by trailer drawbars might be identified incorrectly or not at all. Rsnowfall or heavy rain may lead to a parking
space being measured inaccurately.
Rpay attention to the PARKTRONIC
(Y page 179) warning messages during the parking procedure.
Rwhen transporting a load which protrudes from your vehicle, you must not use Parking Guidance.
Rnever use Parking Guidance with snow
chains or an emergency spare wheel installed.
Rmake sure that the tire pressures are
always correct. This has a direct effect on the steering instructions.
Rthe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. In some cases, Parking Guidance may guide you too far or not far enough into a parking space. In some cases, it may also lead you across or onto the curb. If necessary, cancel the parking procedure with Parking Guidance.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires.
Detecting a parking space
: Detected parking space on the left ; Parking symbol = Detected parking space on the right Parking Guidance is automatically activated when you drive forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the system independently locates and measures parking spaces on both sides of the vehicle. When driving at speeds below 19 mph (30 km/h), you will see parking symbol ; as a status indicator in the instrument cluster.
When a parking space has been detected, an arrow towards the right = or the left : also appears. Parking Guidance only displays parking spaces on the front-passenger side as standard. Parking spaces on the driver's side are displayed as soon as the turn signal on the driver's side is activated. To park on the driver's side, you must leave the driver's side turn signal switched on until you have engaged reverse gear. Parking Guidance will only detect parking spaces: Rthat are parallel to the direction of travel Rthat are at least 5 ft (1.5 m) wide Rthat are at least 4.3 ft (1.3 m) longer than
your vehicle
A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it.
Parking G WARNING The Parking Guidance is only an aid and may not detect all obstacles. The Parking Guidance does not relieve you of the responsibility to pay attention. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering. Otherwise, you could endanger yourself and others.

ATTENTION ASSIST Important safety notes ATTENTION ASSIST helps you during long, monotonous journeys such as on freeways and interstate highways. It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break. 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 using COMAND or
making a telephone call with it
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: Time for a rest? 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.
Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 186) and Lane Keeping Assist (Y page 188).
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 supports you from speeds of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. 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.

For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 210) 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.
Example: Coupe 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 long vehicles, such as 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 rear sensors must not be covered, for example by bicycle racks or overhanging loads. 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. 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 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 210) and Blind Spot Assist (Y page 207) are activated in the on-board computer.

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. If you have chosen the (Y page 208) function in the on-board computer and select as the unit of measurement, Active Lane Keeping Assist is active from speeds of 60 km/h. If the display unit is selected, the assistance range begins at 40 mph. G WARNING Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to
insufficient illumination of the road, or due to snow, rain, fog or spray.
Rthere is glare, e.g. from oncoming traffic, the sun, or reflection from other vehicles.
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the vicinity of the camera.
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.

Important safety notes
You will find an illustration of the instrument cluster in the "At a glance" section (Y page 27). G WARNING A driver's attention to the road and traffic conditions must always be his/her primary focus when driving. For your safety and the safety of others, selecting features through the multifunction steering wheel should only be done by the driver when traffic and road conditions permit it to be done safely. Bear in mind that at a speed of just 30 mph (approximately 50 km/h ), your vehicle is covering a distance of 44 feet (approximately 14 m) every second. G WARNING No messages will be displayed if either the instrument cluster or the multifunction display is inoperative. As a result, you will not be able to see information about your driving conditions, such as Rspeed Routside temperature Rwarning/indicator lamps
Rmalfunction/warning messages Rfailure of any systems Driving characteristics may be impaired. If you must continue to drive, do so with added caution. Contact an authorized Mercedes- Benz Center as soon as possible. G WARNING Malfunction and warning messages are only indicated for certain systems and are intentionally not very detailed. The malfunction and warning messages are simply a reminder with respect to the operation of certain systems. They do not replace the owner's and/or driver's responsibility to maintain the vehicle's operating safety. Have all required maintenance and safety checks performed on the vehicle. Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.
Displays and operation Coolant temperature display G WARNING Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.
The coolant temperature gauge is in the instrument cluster on the right-hand side. Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †).
Displays and operation 197
! If the coolant temperature is too high a
display message is shown. If the coolant temperature rises above 248 ‡(120 †), do not drive any further as this could damage the engine.
Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as
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). G WARNING The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. 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 164) activated: The segments light up from the stored speed to the maximum speed. DISTRONIC PLUS (Y page 166) 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.
