Releasing the seat belts X Press seat belt release button ?

(Y page 47). Allow the retractor to completely rewind the seat belt by guiding latch plate ; (Y page 47).

! Make sure the seat belt retracts

completely. Otherwise the seat belt and/or latch plate could get caught or pinched in the door or in the seat mechanism. This can damage the seat belt and impair its effectiveness, and/or cause damage to the door and/or door trim panel. Such damage is not covered by the Mercedes-Benz Limited Warranty. Damaged seat belts must be replaced. Contact an authorized Mercedes-Benz Center.

Enhanced seat belt reminder system When the engine is started, the seat belt telltale 7 will always illuminate for 6 seconds to remind you and your passengers to fasten your seat belts. If the driver’s seat belt is not fastened when the engine is started, an additional warning chime will sound. The warning chime goes out after approximately 6 seconds or once the driver’s seat belt is fastened. If after these 6 seconds the driver’s or the front passenger’s seat belt (with the front passenger seat occupied) is not fastened with both doors closed, Rthe seat belt telltale 7 remains

illuminated for as long as either the driver’s or front passenger’s seat belt is not fastened.

Rand if the vehicle speed once exceeds

15 mph (25 km/h), the seat belt telltale 7 starts flashing and a warning chime sounds with increasing intensity for a

maximum of 60 seconds or until the driver’s and front passenger’s seat belt are fastened. If you and/or your passenger release the seat belt during driving, the seat belt telltale 7 starts flashing and the warning chime sounds as described before. If the driver’s or the front passenger’s seat belt remains unfastened after 60 seconds, the warning chime stops sounding, the seat belt telltale 7 stops flashing but continues to be illuminated. After a vehicle standstill, the warning chime is reactivated and the seat belt telltale 7 is flashing again if the vehicle speed once exceeds 15 mph (25 km/h).

The seat belt telltale 7 will only go out if both the driver’s and the front passenger’s seat belt (with the front passenger seat occupied) are fastened, or the vehicle is standing still and a door is opened. For more information, see “Practical hints” (Y page 454).

Emergency Tensioning Device (ETD), seat belt force limiter The seat belts are equipped with ETDs and seat belt force limiters. The ETDs are designed to activate in the following cases: Rin frontal or rear-end impacts exceeding

the system’s preset deployment threshold

Rin side impacts exceeding the system’s preset deployment threshold on the far side of the impact

Rin certain vehicle rollovers Rif the restraint systems are operational and

functioning correctly, see “SRS indicator lamp” (Y page 36)

The ETDs for the front seats will only activate if the front seat belts are fastened (latch plate properly inserted into buckle).

Version: 2.11.8.1

The ETDs for the rear seats will activate with or without the respective seat belts fastened. In an impact, the ETDs remove slack from the seat belts in such a way that the seat belts fit more snugly against the body. Seat belt force limiters, when activated, are employed to help reduce the peak force exerted by the seat belts on occupants during a crash. i The ETDs do not correct an incorrect seat

position or incorrectly worn seat belts. The ETDs do not pull occupants back toward the seat backrest. G Warning! Pyrotechnic ETDs that were activated must be replaced. For your safety, when disposing of the pyrotechnic ETDs always follow our safety instructions. These are available at any authorized Mercedes-Benz Center.

Automatic comfort-fit feature seat belt An automatic comfort-fit feature for the front seats reduces the retracting force of the seat belts when they are in normal use.

Preventive occupant safety (PRE- SAFE®) G Warning! The PRE-SAFE® system is intended to reduce the effects of an accident on vehicle occupants who are wearing their seat belt properly. Despite your vehicle being equipped with the PRE-SAFE® system, the possibility of personal injuries occurring as a result of an accident cannot be eliminated. Therefore, always drive carefully and adjust your driving to the prevailing road, weather, and traffic conditions.

Occupant safety

49

The PRE-SAFE® system takes preventive measures to better protect the occupants from the possibility of personal injuries in the following hazardous situations: Remergency braking situations, e.g. if the Brake Assist System (BAS) (Y page 57) is activated or when vehicles with DISTRONIC PLUS: the BAS PLUS (Y page 57) or the PRE- SAFE® Brake (Y page 62) is strongly engaging

Rcritical dynamic driving situations, e.g. when the vehicle has been caused to understeer or oversteer because it has exceeded its physical limitations or in case of evasive steering maneuvers at speeds above approximately 85 mph (140 km/h) The PRE-SAFE® system takes the following measures when it is activated: RIf the front passenger seat is in an

unfavorable position, the seat will be adjusted to a position that seeks to better protect the occupant.

RThe system increases the air pressure in the air pockets (on the sides of the seat cushion and backrest) of the drive-dynamic multicontour front seats.

RIf the vehicle is in a critical dynamic driving

situation, the door windows and the tilt/ sliding sunroof also closes, except for a minimal gap that remains open.

If the closing procedure of any of these elements is blocked, it will stop and open slightly. Once the hazardous situation no longer exists and an accident has been avoided, the PRE- SAFE® system decreases the air pressure in the air pockets of the drive-dynamic multicontour front seats. All of the PRE- SAFE® system settings can be re-adjusted following the critical driving event.

The use of infant or child restraints is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces. Infants and small children should be seated in an appropriate infant or child restraint system. They must be properly secured in accordance with the manufacturer’s instructions for the child restraint. All infant or child restraint systems must comply with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. A statement by the child restraint manufacturer of compliance with these standards can be found on the instruction label on the restraint and in the instruction manual provided with the restraint. When using any infant restraint, toddler restraint, or booster seat, make sure to carefully read and follow all manufacturer’s instructions for installation and use. Please read and observe warning labels affixed to the inside of the vehicle and to infant or child restraints.

G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions. Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat: RYour vehicle is equipped with air bag

technology designed to deactivate the front passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front passenger seat. RA child in a rear-facing child restraint on the

front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly

216_AKB; 3; 90, en-US d2ureepe,

2009-05-15T11:47:50+02:00 - Seite 53
Version: 2.11.8.1

recommend that you always place a child in a rear-facing child restraint in a backseat.

RIf you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 42
indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 42
indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 42 indicator lamp while driving to make sure the 42
indicator lamp is illuminated. If the 42 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired. A child in a rear-facing child restraint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.

RIf you have to place a child in a forward-

facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. For children larger than the typical 12-month- old child, the front passenger front air bag may or may not be activated. G Warning! Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt. A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint.

Occupant safety

53

Children too big for a toddler restraint must ride in seats using regular seat belts. Position shoulder belt across chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster. When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.

Installation of infant and child restraint systems G Observe Safety notes, see page 51. This vehicle is equipped with tether anchorages for a top tether strap at each of the rear seating positions. Top tether straps enable an additional connection to be made between child restraint systems secured with LATCH-type (ISOFIX) anchors and rear seats. This can further reduce the risk of injury.

X Remove anchorage ring cover : from the anchorage ring of the seat on which a child seat is to be installed.

X Store anchorage ring cover : in a convenient place (e.g. glove box).

A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster. Install child seat according to manufacturer’s instructions. The child seat must be firmly attached to both anchors. An incorrectly mounted child seat may come loose during an accident which could result in serious injury or death to the child. Damaged or impact damaged child seats or child seat mounting fittings must be replaced. Each rear seat has two LATCH-type (ISOFIX) anchors for the installation of a LATCH-type (ISOFIX) child seat with matching mounting fittings. Non-LATCH-type (ISOFIX) child seats may also be used and can be installed using the vehicle’s seat belt system. Install child seat according to the manufacturer’s instructions. The LATCH-type (ISOFIX) anchors are covered with upholstery blends.

Driving safety systems Introduction This section contains information about the following driving safety systems: RABS (Antilock Brake System) RAdaptive Brake RAdaptive Brake Lights RBAS (Brake Assist System) RBAS PLUS (Brake Assist System PLUS) REBP (Electronic Brake Proportioning)

RESC (Electronic Stability Control) RPRE-SAFE® Brake (Preventive Occupant

Safety System Brake)

i In winter operation, the maximum effectiveness of most of the driving systems described in this section is only achieved with winter tires, or snow chains as required.

Safety notes G Warning! The following factors increase the risk of accidents: RExcessive speed, especially in turns RWet and slippery road surfaces RFollowing another vehicle too closely The driving safety systems described in this section cannot reduce these risks or prevent the natural laws of physics from acting on the vehicle. They cannot increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a vehicle equipped with the driving safety systems described in this section must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others. Always adjust your driving style to the prevailing road and weather conditions and keep a safe distance to other road users and objects on the street. If a driving system malfunctions, other driving safety systems may also switch off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear.

Version: 2.11.8.1

ABS G Observe Safety notes, see page 56. G Warning! Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pumping the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness. The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not lock during braking. This allows you to maintain the ability to steer your vehicle. The ABS is functional above a speed of approximately 5 mph (8 km/h) independent of road surface conditions. On slippery road surfaces, the ABS will respond even to light brake pressure. The ABS indicator lamp ! in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.

Braking At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal. The pulsation indicates that the ABS is in the regulating mode. X Keep firm and steady pressure on the brake

pedal while you feel the pulsation.

Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.

Emergency brake maneuver X Keep continuous full pressure on the brake

pedal.

Driving safety systems

57

G Warning! If the ABS malfunctions, other driving safety systems such as the BAS or the ESC are also switched off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear. If the ABS malfunctions, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.

BAS G Observe Safety notes, see page 56. The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance. X Apply continuous full braking pressure until

the emergency braking situation is over. The ABS will prevent the wheels from locking.

When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated. G Warning! If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.

BAS PLUS The Brake Assist System PLUS (BAS PLUS) operates in emergency braking situations and uses radar sensors to assess the traffic situation. BAS PLUS assists you in braking at speeds above approximately 20 mph (30 km/h). When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 216). Canadian law does not permit the use of the radar

216_AKB; 3; 90, en-US d2ureepe,

sensor system for vehicles from outside of Canada. When you switch off the radar system, the following functions are deactivated: RBAS PLUS RPRE-SAFE® Brake (Y page 62) RDISTRONIC PLUS (Y page 304) RPark Assist (Y page 324) RBlind Spot Assist (Y page 335) RAdvanced Parking Guidance (Y page 327) G Warning! BAS PLUS is a convenience system designed to assist the driver during vehicle operation. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver. Always pay attention to traffic conditions even while BAS PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident. Personal or fatal injury to you or others may be the result.

i 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 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.

BAS PLUS detects obstacles that are in your driving path for a sufficient period of time to permit the system to recognize these obstacles. If you approach the detected obstacle quickly, BAS PLUS calculates the level of brake power boost appropriate for the

circumstance to supply when the driver applies the brakes. When you step quickly on the brake pedal in an emergency braking situation, BAS PLUS automatically regulates the brake power boost to a level that is suitable for the traffic situation. If BAS PLUS requires a particularly high brake power boost, PRE-SAFE® is activated at the same time. X Keep constant pressure on the brake pedal

until the emergency braking situation is over. During this process, the ABS prevents the wheels from locking up.

The brakes will resume normal operation after Rthe brake pedal is released Rno obstacles are detected in your path Rthe system no longer senses a risk of a

collision

BAS PLUS is then deactivated. BAS PLUS can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h). BAS PLUS can only assist you when the radar sensors are switched on and functional. You can check whether the sensors are active by switching on DISTRONIC PLUS (Y page 304) or using the Radar sensors function (Y page 216) in the instrument cluster control system. G Warning! BAS PLUS will only respond with brake assistance if it has clearly detected an object. Detection can be impeded by Rdirty or covered sensors Rsnowfall or heavy rain Rdisturbance from other radar sources Rstrong radar reflection such as in parking

garages

216_AKB; 3; 90, en-US d2ureepe,

2009-05-15T11:47:50+02:00 - Seite 59
Version: 2.11.8.1

BAS PLUS uses radar signals that are not reflected well by narrow objects and absorptive materials. For this reason BAS PLUS will not react to persons, animals, and approaching traffic or cross-traffic. BAS PLUS may not detect narrow vehicles driving in front of you, such as motorcycles and vehicles driving offset from your vehicle center. After a hard collision or damage to the front of the vehicle from an accident, have the adjustment and operation of the radar sensors checked by an authorized Mercedes- Benz Center. If BAS PLUS is not available due to a radar sensor malfunction, the braking system will continue to function normally with full brake boost and full standard BAS function.

Adaptive Brake Adaptive Brake provides a high level of braking safety as well as increased braking comfort. Adaptive Brake takes driver and vehicle characteristics into consideration, thus achieving an optimal braking effect. In addiditon, Adaptive Brake provides the HOLD function (Y page 316) and the hill-start assist system (Y page 315). For more information on the brake system, see (Y page 398).

Adaptive Brake Lights i This function is only available for the

CL 600 (USA only).

The brake lamps flash in quick intervals Rwhile you are braking hard at a speed of

more than 30 mph (50 km/h)

Rwhen you are braking with the aid of BAS Rwhen you are braking with the aid of BAS

This helps to alert drivers behind you.

Driving safety systems

59

If you bring the car to a complete stop by hard braking at a speed of more than 40 mph (70 km/h), the hazard warning flasher comes on automatically as soon as the vehicle is at a standstill. While the vehicle is stationary, the brake lamps are continuously lit up. Once you drive faster than 6 mph (10 km/h) afterward, the hazard warning flasher goes out.

EBP G Observe Safety notes, see page 56. The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion of the braking effort in straight-line braking without a loss of vehicle stability. G Warning! If the EBP malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident. Adapt your driving style to the changed driving characteristics.

ESC G Observe Safety notes, see page 56. The Electronic Stability Control (ESC) is operational as soon as the engine is running. It monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling. The ESC recognizes that the vehicle deviates from the direction of travel as intended by the driver. By applying brakes to individual wheels and by limiting the engine output, the ESC works to stabilize the vehicle. The ESC is especially useful while driving off and on wet or slippery road surfaces. The ESC also stabilizes the vehicle during braking and steering maneuvers.

Electronic Traction System (ETS/4-ETS) G Observe Safety notes, see page 56. The ETS (Electronic Traction System) and 4-ETS (four-wheel Electronic Traction System, vehicles with 4MATIC only) are components of the ESC. The ETS/4-ETS improves the vehicle’s ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. Vehicles with 4MATIC also transfer more power to the wheel(s) with traction. When you switch off the ESC, the ETS/4-ETS is still enabled.

Switching off the ESC Switching off the ESC (except CL 63 AMG) G Warning! The ESC should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. Do not switch off the ESC when a spare wheel is mounted.

The ESC warning lamp ÷ in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running. G Warning! Never switch off the ESC when you see the ESC warning lamp ÷ flashing in the instrument cluster. In this case proceed as follows: RWhen driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The ESC cannot prevent accidents resulting from excessive speed.

! Vehicles with 4MATIC:

Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the electronic parking brake is being tested on a brake test dynamometer. Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.

! Vehicles without 4MATIC:

Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the electronic parking brake is being tested on a brake test dynamometer or when the vehicle is being towed with one axle raised. Active braking action through the ESC may otherwise seriously damage the brake

To improve the vehicle’s traction, switch off the ESC. This allows the drive wheels to spin and thus cut into surfaces for better grip, for example Rwhen driving with snow chains Rin deep snow Rin sand or gravel G Warning! Switch on the ESC immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESC will not stabilize the vehicle when it is starting to skid or a wheel is spinning. When you switch off the ESC, Rthe ESC does not stabilize the vehicle Rthe engine output is not limited, which

! Avoid spinning of a drive wheel for an

extended period with the ESC switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

PRE-SAFE® Brake The PRE-SAFE® Brake is available in vehicles equipped with DISTRONIC PLUS. The PRE- SAFE® Brake can assist you in minimizing the risk of a rear-end collision with a vehicle in front of you. The PRE-SAFE® Brake may also reduce the severity of an accident. At speeds

above approximately 20 mph (30 km/h) it will issue a warning when your vehicle is approaching the preceding vehicle very quickly. An intermittent acoustic warning sounds and the distance warning lamp · in the instrument cluster comes on. When the driver and front passenger have fastened their seat belts, the PRE-SAFE® Brake can also Rbrake the vehicle within a speed range of up to 112 mph (180 km/h) automatically

Ractivate preventative occupant safety

measures (PRE-SAFE®) (Y page 49) G Warning! An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the PRE-SAFE® Brake calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that the PRE-SAFE® Brake will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake your vehicle to increase the distance between your vehicle and the vehicle driving in front of you. The warning sound is intended as a final caution that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking, as that will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. G Warning! The PRE-SAFE® Brake is a convenience system designed to assist the driver during vehicle operation. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver.

slowing the vehicle sufficiently, the system will initially warn you visually and acoustically. If you do not apply the brakes yourself or maneuver around a sensed obstacle, the vehicle will brake lightly automatically. The PRE-SAFE® system (Y page 49) is activated when the distance to the vehicle ahead at your current speed is so close that the PRE- SAFE® Brake will not be capable of slowing the vehicle sufficiently. G Warning! The PRE-SAFE® Brake will only respond with brake assistance if it has clearly detected an object. Detection can be impeded by Rdirty or covered sensors Rsnowfall or heavy rain Rdisturbance from other radar sources Rstrong radar reflection such as in parking

garages

The PRE-SAFE® Brake uses radar signals that are not reflected well by narrow objects and absorptive materials. For this reason the PRE- SAFE® Brake will not react to persons, animals, and approaching traffic or cross- traffic. The PRE-SAFE® Brake may not detect narrow vehicles driving in front of you, such as motorcycles and vehicles driving offset from your vehicle center. G Warning! The PRE-SAFE® Brake brakes your vehicle with a maximum of 13 ft/s2 (4 m/s2). This corresponds to about 40% of the maximum deceleration ability of your vehicle. This automatic braking is intended only to initiate the braking if the driver has not already done so. The driver must apply the brakes in order to prevent a collision. The PRE-SAFE® Brake applies the brake pedal automatically which results in the brake pedal moving. Therefore keep driver’s foot area clear at all times, including the area under the

brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the PRE-SAFE® Brake. Do not place your foot under the brake pedal – your foot could become caught.

To maintain the proper distance to the vehicle in front of you and thus prevent a rear-end collision, you must apply the brakes yourself. X Brake the vehicle immediately to avoid a

collision. Under no circumstances should the driver await the intermittent warning sound before braking. Observe the following warning note. The intermittent warning sound ceases and the distance warning lamp · goes out when the necessary distance to the vehicle ahead is again established.

The PRE-SAFE® Brake can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h). G Warning! If you do not receive visual or acoustic warning signals, the PRE-SAFE® Brake may Rnot have recognized the collision risk Rhave been deactivated Rbe malfunctioning Apply the brakes yourself to avoid a collision.

The PRE-SAFE® Brake does not always clearly interpret complex traffic situations. If a visual and/or acoustic warning is issued in an uncritical driving situation, or if the vehicle brakes lightly, you can interrupt the PRE- SAFE® Brake maneuver by pressing down all the way on the accelerator pedal, using kickdown, or releasing the brake pedal.

The PRE-SAFE® Brake maneuver is terminated immediately when Ryou avoid the obstacle by evasive steering Ryou drive less than 9 mph (15 km/h) Ran obstacle can no longer be identified

ahead of you

Rthe system no longer senses the risk of a

collision

i The PRE-SAFE® Brake will remain passive

while DISTRONIC PLUS is switched on (Y page 304).

After a hard collision or damage to the front of the vehicle from an accident, have the settings and operation of the radar sensors checked by an authorized Mercedes-Benz Center. When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 216). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada. When you switch off the radar system, the following functions are deactivated: RPRE-SAFE® Brake RBAS PLUS (Y page 57) RDISTRONIC PLUS (Y page 304) RPark Assist (Y page 324) RBlind Spot Assist (Y page 335) RAdvanced Parking Guidance (Y page 327) X Activating and deactivating: Activate or deactivate the PRE-SAFE® Brake using the instrument cluster control system (Y page 213). After the function has been activated, the PRE-SAFE® Brake indicator Ä appears in the instrument cluster. When the HOLD function is switched on, the PRE-SAFE® Brake indicator Ä will not appear.

COMAND introduction

Vehicle equipment

i This Operator’s Manual describes all

features, standard or optional, potentially available for your vehicle at the time of purchase. Please be aware that your vehicle might not be equipped with all features described in this manual.

COMAND introduction COMAND operating safety COMAND (Cockpit Management and Data System) is an information and operating center for vehicle sound and communications systems. It includes the radio and navigation system, as well as other optional equipment (satellite radio, telephone, etc.). G Warning! Any alteration of electronic components or software can cause malfunctions. Radio, satellite radio, amplifier, CD/DVD changer, navigation module, telephone and Voice Control Systems are interconnected. Therefore, if one of the components is not operational, or has not been removed/ replaced properly, the function of other components could be impaired. Such conditions might seriously impair the operating safety of your vehicle. We recommend to have any service work on electronic components carried out by an authorized Mercedes-Benz Center. G Warning! In order to avoid distraction which could lead to an accident, the driver should enter system settings while the vehicle is at a standstill, and operate the system only when permitted by road, weather and traffic conditions. 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.

COMAND supplies you with information to help you select your route more easily and guide you conveniently and safely to your destination. For safety reasons, we encourage the driver to stop the vehicle in a safe place before answering or placing a call, or consulting the COMAND screen to read navigational maps, instructions, or downloaded information. G Warning! While the navigation system provides directional assistance, the driver must remain focused on safe driving behavior, especially attention to traffic and street signs, and should utilize the system’s audio cues while driving. The navigation system does not supply any information on stop signs, yield signs, traffic regulations or traffic safety rules. Their observance always remains in the driver’s personal responsibility. Maps do not cover all areas nor all routes within an area.

Availability of functions while the vehicle is in motion For safety reasons, certain COMAND functions are not available while the vehicle is in motion or they are only available to a limited extent. You will notice this, for example, by the fact that certain menu items cannot be selected or that the COMAND display shows a corresponding message.

Switching COMAND on or off X Press shortcut button u in the center

console (Y page 69). COMAND calls up the last selected menu. i When you switch off COMAND, you also

switch off the currently playing audio source. During a telephone call, you cannot switch off COMAND.
