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: RUSA only: Your 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.
RUSA only: For children larger than the
typical 12-month-old child, the front passenger front air bag may or may not be activated. Always make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.
RCanada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.

Version: 2.11.8.1RA 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 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 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure the 45 indicator lamp is illuminated. If the 45 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. 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. 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 56. G Warning! Always lock the seat backrests in their upright position when the rear seats are occupied by passengers. Lock the seat backrests in their upright position before installing top tether straps or when the extended cargo compartment is not in use. Make sure that seat backrests are secured properly by pushing and pulling on the seat backrests. If a seat backrest is not locked properly, the seat backrest could fold. The child seat would no longer be supported properly or positioned to provide its intended benefit. That could cause serious or even fatal injuries. 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.

Version: 2.11.8.162 Driving safety systems
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.
ABS G Observe Safety notes, see page 62. 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.

2009-07-17T09:14:21+02:00 - Seite 63
Version: 2.11.8.1G 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 62. 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 144). Canadian law does not permit the use of the radar
Driving safety systems
63
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 69) RDISTRONIC PLUS (Y page 149) 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
212_AKB; 2; 41, en-US d2ureepe,
2009-07-17T09:14:21+02:00 - Seite 64
Version: 2.11.8.164 Driving safety systems
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 149) or using the Radar sensors function 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
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 161) and the hill-start assist system (Y page 160). For more information on the brake system, see (Y page 254).
EBP G Observe Safety notes, see page 62. 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.

Version: 2.11.8.1ESC G Observe Safety notes, see page 62. 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. The ESC warning lamp ä 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 ä 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 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 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 system which is not covered by the Mercedes-Benz Limited Warranty.
! The ESC will only function properly if you use wheels of the recommended tire size as specified in the “Technical data” section of this Operator’s Manual.
i The DISTRONIC PLUS and cruise control
switch off automatically when the ESC engages.
Electronic Traction System (ETS/4-ETS) G Observe Safety notes, see page 62. 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.

When the ESC warning lamp ä and the ESC OFF warning lamp å are on continuously, the ESC is not operational due to a malfunction. When the ESC is switched off or not operational, vehicle stability in standard driving maneuvers is reduced. Adapt your speed and driving to the prevailing road conditions and to the non-operating status of the ESC.
! 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.
X Switching on: With the engine running,
press ESC switch : briefly. The ESC OFF warning lamp å in the instrument cluster goes out. The message ESC-ON appears in the multifunction display.
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. Due to the system characteristics, warnings could be issued without cause in complex driving situations.
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 124 mph (200 km/h) automatically
Ractivate preventative occupant safety
measures (PRE-SAFE®) (Y page 53) 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. Always pay attention to traffic conditions even while the PRE-SAFE® Brake is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident resulting in personal or fatal injury to you or others.

Version: 2.11.8.170 Driving safety systems
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 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.
i Canada only:
This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference,
and this device must accept any interference received, including interference that may cause undesired operation of the device.
2.
Removal, tampering, or altering of the device will void any warranties, and is not permitted. 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.
Using the radar sensors, the PRE-SAFE® Brake detects obstacles that are in your driving path for a sufficient period of time for the system to recognize it. If you approach a vehicle and the PRE-SAFE® Brake has established that 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, 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 53) 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. When the danger of a collision still persists and you do not brake or accelerate significantly, the PRE-SAFE® Brake may initiate full application of the brakes automatically. 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! Depending on the vehicle speed, the PRE-SAFE® Brake brakes your vehicle with a maximum of 13 ft/s2 (4 m/s2) before a possible hard stop. This corresponds to about 40% of the maximum deceleration ability of your vehicle. The driver must apply the brakes additionally in order to prevent a collision. The self-acting hard stop will be initiated when the imminent danger of a collision exists, e.g. when an evasive driving maneuver cannot avoid an accident.

Version: 2.11.8.1To 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
