2013 Mercedes-benz E Class Owners Manual

head restraints increase protection of the

driver's and front-passenger's head and neck. In the event of a rear collision of a certain severity, the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and the front-passenger seats are moved forwards and upwards. This provides better head support. If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats (Y page 54). Otherwise, the additional protection will not be available in the event of another rear-end collision. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted. Mercedes-Benz recommends that you have the NECK-PRO head restraints/NECK-PRO luxury head restraints checked at a qualified specialist workshop after a rear-end collision.

PRE-SAFE® (anticipatory occupant protection system) ! Make sure that there are no objects in the footwell or behind the seats when resetting the seats. There is a risk that the seats and/or the objects could be damaged. PRE-SAFE® takes preemptive measures to protect occupants in certain hazardous situations. 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. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. PRE-SAFE® intervenes: Rif BAS intervenes, e.g. in emergency

braking situations.

Rif BAS PLUS intervenes powerfully — on

vehicles with DISTRONIC PLUS.

Rif, on vehicles with DISTRONIC PLUS, the radar sensor system detects an imminent danger of collision in certain situations. Rin critical driving situations, e.g. when physical limits are exceeded and the vehicle understeers or oversteers severely.

PRE-SAFE® takes the following measures depending on the hazardous situation detected: Rthe front seat belts are pre-tensioned. Rthe front-passenger seat is adjusted if it is

in an unfavorable position.

Rthe air pressure in the side bolsters of the seat cushion and seat backrest of the front active multicontour seats is increased.

Rif the vehicle skids, the sliding sunroof and the side windows are closed so that only a small gap remains. On vehicles with a panorama roof with power tilt/sliding panel, they are closed completely.

If the hazardous situation passes without resulting in an accident, PRE-SAFE® slackens the belt pre-tensioning. The air pressure in the side bolsters of the active multicontour seat is reduced again. All settings made by PRE-SAFE® can then be reversed. If the seat belts are not released: X When the vehicle is stationary, move the

backrest or seat back slightly. The seat belt pre-tensioning is reduced and the locking mechanism is released.

Information about seat belt adjustment, a convenience function integrated into PRE- SAFE®, can be found in the "Seat belt adjustment" section (Y page 57).

Seat belts Important safety notes G WARNING The seat belt does not offer the intended level of protection if the backrest is not in the upright position. When braking or in the event

of an accident, you could slide underneath the seat belt and sustain abdomen or neck injuries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always make sure that the seat is in the upright position. G WARNING Seat belts cannot protect as intended, if: Rthey are damaged, extremely dirty,

bleached or dyed

Rthe seat belt buckle is damaged or

extremely dirty

Rthe Emergency Tensioning Devices or the

belt anchorage has been modified.

Damage caused to seat belts in an accident may not be visible, e.g. by splinters of glass. Modified or damaged seat belts can tear or fail, for example in the event of an accident. Modified Emergency Tensioning Devices may be deployed unintentionally or fail to be deployed when required. There is an increased risk of injury, possibly even fatal. Never modify seat belts, Emergency Tensioning Devices, seat belt anchorages and inertia reels. Ensure that seat belts are not damaged or worn and are clean.

Only use seat belts that have been approved for your vehicle by Mercedes-Benz. The use of seat belts and infant and child restraint systems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey. i See "Children in the vehicle"

(Y page 60) for further information on infants and children traveling in the vehicle as well as on child restraint systems.

56 Occupant safety

Correct use of the seat belts G WARNING USE SEAT BELTS PROPERLY RSeat belts can only work when used

properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in the event of an accident.

REach occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. The integrated restraint system includes SRS (driver front air bag, driver's side knee bag, front-passenger front air bag, side impact air bags, pelvis air bags, window curtain air bags for the side windows), Emergency Tensioning Devices, seat belt force limiters, and front seat knee bolsters. The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags, driver's side knee bag and ETDs) and side (side impact air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs).

RNever wear the shoulder belt under your

arm, across your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen. Adjust the seat belt so that the shoulder section is located as close as possible to the middle of the shoulder. It should not touch the neck. Never pass the shoulder portion of the seat belt under your arm. For this purpose, you can adjust the height of the seat belt outlet.

RPosition the lap belt as low as possible on your hips and not across the abdomen. If the lap belt is positioned across your abdomen, it could cause serious injuries in a crash.

RNever wear seat belts over rigid or

breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries.

RMake sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.

RNever use a seat belt for more than one

person at a time. Do not fasten a seat belt around a person and another person or other objects at the same time.

RSeat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries.

RPregnant women should also always use a

lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen.

RPlace the seat backrest in a position that is

as upright as possible.

RCheck your seat belt during travel to make

sure it is properly positioned.

RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.

RWhen using a seat belt to secure infant

restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer's instructions.

Fastening seat belts G WARNING According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be

placed in the rear seat whenever possible. Regardless of seating position, children 12
years old and under must be seated and properly secured in an appropriately sized child restraint system or booster seat recommended for the size and weight of the child. For additional information, see the "Children in the vehicle" section. 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.

Belt warning for the driver and front passenger Regardless of whether the driver's and front- passenger seat belts have already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. It then goes out if the driver and the front passenger have already fastened their seat belts. If the driver's seat belt is not fastened when the engine is started, an additional warning tone will sound. This warning tone stops after a maximum of six seconds or once the driver's seat belt is fastened.

If after six seconds, the driver or front passenger have not fastened their seat belts and the doors are closed: Rthe 7 seat belt warning lamp remains lit as long as the driver's or front-passenger's seat belt is not fastened and

Rif a vehicle speed of 15 mph (25 km/h) is exceeded, the 7 seat belt warning lamp begins to flash. A warning tone also sounds with increasing intensity for a maximum of 60 seconds or until the driver or front passenger have fastened their seat belts. If the driver/front passenger unfasten their seat belt while the vehicle is in motion, the 7 seat belt warning lamp lights up and a warning tone sounds again. The warning tone ceases even if the driver or front-passenger seat belt has still not been fastened after 60 seconds. The 7 seat belt warning lamp stops flashing but remains illuminated. After the vehicle comes to a standstill, the warning tone is reactivated and the seat belt warning lamp 7 flashes again if the vehicle speed again exceeds 15 mph (25 km/h). The 7 seat belt warning lamp only goes out if: Rboth the driver and the front passenger

have fastened their seat belts. or

Rthe vehicle is stationary and a door is open. i For more information on the 7 seat

belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belts" (Y page 285).

Emergency Tensioning Devices, seat belt force limiters G WARNING Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer operational and are unable to perform their

59

intended protective function. This poses an increased risk of injury or even fatal injury. Therefore, have pyrotechnic Emergency Tensioning Devices which have been triggered immediately replaced at a qualified specialist workshop.

! If the front-passenger seat is not

occupied, do not engage the seat belt tongue in the buckle on the front- passenger seat. Otherwise, the Emergency Tensioning Device could be triggered in the event of an accident.

i Vehicles with PRE-SAFE®: Emergency

Tensioning Devices that are triggered by an electric motor can be deployed as often as desired and do not need to be replaced.

The front seat belts and the outer seat belts in the rear are equipped with Emergency Tensioning Devices and seat belt force limiters. The ETDs tighten the seat belts in an accident, pulling them close against the body. The ETDs do not correct incorrect seat positions or incorrectly fastened seat belts. The ETDs do not pull vehicle occupants back towards the backrest. The ETDs can only be activated when: Rthe ignition is switched on Rthe restraint systems are operational; see

"SRS warning lamp 6" (Y page 41)

Rthe belt tongue is engaged in the buckle on

each of the front seat belts

The ETDs on the outside seats in the rear compartment are triggered independently of the lock status of the seat belts. The ETDs are triggered depending on the type and severity of an accident: Rin the event of a head-on or rear-end collision if the vehicle decelerates or accelerates rapidly in a longitudinal

60

Children in the vehicle

direction during the initial stages of the impact.

Rin the event of a side impact if the vehicle

decelerates or accelerates rapidly in a lateral direction on the side opposite to the impact.

Rin certain situations where the vehicle rolls

over if the system determines that it can provide additional protection.

If the ETDs are deployed, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so. You can also open the window to allow fresh air to enter the vehicle interior. The 6 SRS warning lamp lights up. If the seat belt is also equipped with a seat belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced. The seat belt force limiters for the front seats are synchronized with the front air bags, which absorb part of the deceleration force. This results in the force exerted on the occupant being distributed over a greater area.

Children in the vehicle Child restraint systems Important safety notes 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.

RFor 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 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.

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

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 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 4 5 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 4 5 indicator lamp while driving to make sure the 4
5 indicator lamp is illuminated. If the 4 5 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 If the child restraint system is installed incorrectly on a suitable seat, it cannot protect as intended. The child cannot then be restrained in the event of an accident, heavy braking or sudden changes of direction. There is an increased risk of injury, possibly even fatal. Make sure that you observe the child restraint system manufacturer's installation instructions and the notes on use. Please ensure, that the base of the child restraint system is always resting completely on the seat cushion. Never place objects, e.g. cushions, under or behind the child restraint

system. Only use child restraint systems with the original cover designed for them. Only replace damaged covers with genuine covers. G WARNING If the child restraint system is installed incorrectly or is not secured, it can come loose in the event of an accident, heavy braking or a sudden change in direction. The child restraint system could be thrown about, striking vehicle occupants. There is an increased risk of injury, possibly even fatal. Always install child restraint systems properly, even if they are not being used. Make sure that you observe the child restraint system manufacturer's installation instructions. G WARNING Child restraint systems or their securing systems which have been damaged or subjected to a load in an accident can no longer protect as intended. The child cannot then be restrained in the event of an accident, heavy braking or sudden changes of direction. There is an increased risk of injury, possibly even fatal. Replace child restraint systems which have been damaged or subjected to a load in an accident as soon as possible. Have the securing systems on the child restraint system checked at a qualified specialist workshop, before you install a child restraint system again. G WARNING Infants and small children should never share a seat belt with another occupant. In the event of 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.

62

Children in the vehicle

Children that are too large for a child restraint must travel in seats using normal seat belts. Position the shoulder belt across the chest and shoulder, not the face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lbs (18 kg) until they reach a height where a lap/ shoulder belt fits properly without a booster seat. 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. G WARNING If children are left unsupervised in the vehicle, they could: Ropen the doors, thus endangering other

people or road users.

Rget out and disrupt traffic. Roperate the vehicle's equipment. Additionally, children could set the vehicle in motion if, for example, they: Rrelease the parking brake. Rshifting the automatic transmission out of

park position P RStart the engine. There is a risk of an accident and injury. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. Never leave children or animals unattended in the vehicle. Always keep the SmartKey out of reach of children. G WARNING If persons, particularly children are subjected to prolonged exposure to extreme heat or cold, there is a risk of injury, possibly even fatal. Never leave children unattended in the vehicle. G WARNING If the child restraint system is subjected to direct sunlight, parts may get very hot.

Children may burn themselves on these parts, particularly on the metal parts of the child restraint system. There is a risk of injury. If you leave the vehicle, taking the child with you, always ensure that the child restraint system is not exposed to direct sunlight. Protect it with a blanket, for example. If the child restraint system has been exposed to direct sunlight, let it cool down before securing the child in it. Never leave children unattended in the vehicle.

If an infant or child is traveling in the vehicle: RSecure the child with a child or infant seat restraint system appropriate to the age and weight of the child.

RMake sure that the infant or child is

properly secured at all times while the vehicle is in motion.

Mercedes-Benz recommends that you always properly secure all infants and children with a child or infant seat restraint system for the trip. The use of seat belts and infant and child restraint systems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces Infants and children must always be seated in an appropriate infant or child restraint system recommended for the size and weight of the child. The infant or child restraint system must be properly secured in accordance with the manufacturer's instructions. All infant or child restraint systems must meet the following standards: RU.S. Federal Motor Vehicle Safety

Standards 213 and 225

RCanadian Motor Vehicle Safety Standards

213 and 210.2

Confirmation that the child restraint system corresponds to the standards can be found on an instruction label on the child restraint system. This confirmation can also be found

in the installation instructions that are included with the child restraint system. Always read and follow the manufacturer's instructions when using an infant or child restraint system or booster seat. Observe the warning labels in the vehicle interior or on the infant or child restraint. Do not install a rearward-facing child restraint system on the center rear seat.

Special seat belt retractor G WARNING If the seat belt is released while driving, the child restraint system will no longer be secured properly. The special seat belt retractor is disabled and the inertia real draws in a portion of the seat belt. The seat belt cannot be immediately refastened. There is an increased risk of injury, possibly even fatal. Stop the vehicle immediately, paying attention to road and traffic conditions. Reactivate the special seat belt retractor and secure the child restraint system properly.

All seat belts in the vehicle, excluding the driver's seat belt and the seat belts of the folding bench seat in the cargo compartment, are equipped with a special seat belt retractor. When activated, the special seat belt retractor ensures that the seat belt will not slacken once the child restraint system has been secured.

LATCH-type (ISOFIX) child seat anchors in the rear G WARNING LATCH-type (ISOFIX) child restraint systems do not offer sufficient protective effect for children whose weight is greater than 48 lbs (22 kg) who are secured using the safety belt integrated in the child restraint system. In the event of an accident, a child might not be restrained correctly. This poses an increased risk of injury or even fatal injury. If the child weighs more than 48 lbs (22 kg), only use LATCH-type (ISOFIX) child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the Top Tether belt, if available.

When installing a child restraint system, be sure to observe the manufacturer's installation instructions and the instructions for correct use of the child restraint system. ! When installing the LATCH-type (ISOFIX) child restraint system, make sure that the

When installing the LATCH-type (ISOFIX) child restraint system, fold protective caps ; of LATCH-type (ISOFIX) securing rings : inwards. X Install the LATCH-type (ISOFIX) child restraint system on both LATCH-type (ISOFIX) securing rings :. Comply with the child restraint system manufacturer's instructions when installing the LATCH- type (ISOFIX) child restraint system. LATCH-type (ISOFIX) is a standardized securing system for specially designed child restraint systems on the rear seats. The LATCH-type (ISOFIX) securing rings for two LATCH-type (ISOFIX) child restraint systems are installed on the left and right of the rear seats. Non-LATCH-type (ISOFIX) child seats may also be used and can be installed using the vehicle's seat belt system. Install the child seat according to the manufacturer's instructions.

Top Tether Important safety notes G WARNING If the rear seat backrests are not locked, they could fold forwards in the event of an accident, heavy braking or sudden changes of direction. As a result, child restraint systems cannot perform their intended protective

function. Rear seat backrests that are not locked can also cause additional injuries, e.g. in the event of an accident. This poses an increased risk of injury or even fatal injury. Always lock rear seat backrests after installing a Top Tether belt. Observe the lock verification indicator. Adjust the rear seat backrests so that they are positioned vertically.

Top Tether provides an additional connection between a child restraint system, secured with a LATCH-type (ISOFIX) child seat mount, and the rear seat. This helps reduce the risk of injury even further. If the rear seat backrest is not engaged and locked, this will be shown in the multifunction display in the instrument cluster.

Important safety notes If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road, weather and traffic conditions and maintain a safe distance from the vehicle in front. Drive carefully.

i The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Please pay special attention to the notes on tires, recommended minimum tire tread depths, etc. (Y page 372). In wintry driving conditions, always use winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible.

ABS (Anti-lock Braking System) General information ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. The yellow ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.

Important safety notes i Observe the "Important safety notes"

section (Y page 67). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.

When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 288) and display messages which may be shown in the instrument cluster (Y page 258).

68 Driving safety systems

ABS works from a speed of about 5 mph (8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even if you only brake gently.

Braking X If ABS intervenes: continue to depress the

brake pedal vigorously until the braking situation is over.

X To make a full brake application:

depress the brake pedal with full force.

If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving.

BAS (Brake Assist System) General information BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance.

Important safety notes i Observe the "Important safety notes"

section (Y page 67). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking.

Braking X Keep the brake pedal firmly depressed until

the emergency braking situation is over. ABS prevents the wheels from locking.

The brakes will function as usual once you release the brake pedal. BAS is deactivated.

BAS PLUS (Brake Assist System PLUS) with Cross-Traffic Assist General information i Observe the "Important safety notes"

section (Y page 67).

BAS PLUS is only available on vehicles with the Driving Assistance package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a camera system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an

extended period of time

Rthat cross the path of your vehicle In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians by using typical characteristics such as the body contours and posture of a person standing upright. If the radar sensor system or the camera system is malfunctioning, BAS PLUS functions are restricted or no longer available. The brake system is still available with complete brake boosting effect and BAS. i Observe the restrictions described in the

"Important safety notes" section“ (Y page 69).

BAS PLUS can help you to minimize the risk of a collision with a vehicle or a pedestrian and reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking.

Important safety notes G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. In such cases, BAS PLUS may: Rintervene unnecessarily Rnot intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. G WARNING BAS PLUS does not react: Rto small people, e.g. children Rto animals Rto oncoming vehicles Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.

In the event of snowfall or heavy rain, the recognition can be impaired. Recognition by the radar sensor system is also impaired in the event of: Rdirt on the sensors or anything else

covering the sensors

Rinterference by other radar sources Rthere are strong radar reflections, for

example in parking garages

Ra narrow vehicle traveling in front, e.g. a

motorbike

Ra vehicle traveling in front on a different line Rvehicles quickly moving into the radar

sensor system detection range

Driving safety systems

69

Recognition by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is

covered

Rthere is glare on the camera system, e.g.

from the sun being low in the sky

Rdarkness Rif:

- pedestrians move quickly, e.g. into the

path of the vehicle the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects

- a pedestrian is concealed by other

objects the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera system checked at a qualified specialist workshop.

Function To avoid a collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and RBAS PLUS has detected a risk of collision When driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possible moment. When driving at a speed above 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traffic situation.

70 Driving safety systems

BAS PLUS provides braking assistance in hazardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and 155 mph (250 km/h). At speeds of up to approximately 44 mph (70 km/h), BAS PLUS reacts to: Rstationary objects in the path of your

vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robjects crossing your path i If BAS PLUS demands particularly high

braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously.

X Keep the brake pedal depressed until the

emergency braking situation is over. ABS prevents the wheels from locking. BAS PLUS is deactivated and the brakes function as usual, if: Ryou release the brake pedal Rthere is no longer a risk of collision Rno obstacle is detected in front of your

vehicle

Ryou depress the accelerator pedal Ryou activate kickdown

COLLISION PREVENTION ASSIST General notes COLLISION PREVENTION ASSIST consists of the distance warning function and adaptive Brake Assist, which are described in the following section.

Distance warning function Important safety notes i Observe the "Important safety notes"

section (Y page 67).

G WARNING The distance warning function does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. In such cases, the distance warning function may: Rgive an unnecessary warning Rnot give a warning There is a risk of an accident. Always pay careful attention to the traffic situation and do not rely solely on the distance warning function.

Function X To activate/deactivate: activate or

deactivate the distance warning function in the on-board computer (Y page 247). If the distance warning function is not activated, the æ symbol appears in the assistance graphics display. The distance warning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically. The distance warning function cannot prevent a collision without your intervention. Starting at a speed of around 4 mph (7 km/h), the distance warning function warns you if you rapidly approach a vehicle in

front. An intermittent warning tone will then sound, and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the

distance from the vehicle in front.

or X Take evasive action, provided it is safe to

do so.

Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the system to display a warning. With the help of the radar sensor system, the distance warning function can detect obstacles that are in the path of your vehicle for an extended period of time. From a speed of around 40 mph (70 km/h), the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles. If you approach an obstacle and the distance warning function detects a risk of a collision, the system will initially alert you both visually and acoustically. In particular, the detection of obstacles can be impaired if: Rdirt on the sensors or anything else

covering the sensors

Rsnow or heavy rain Rinterference by other radar sources Rthere are strong radar reflections, for

example in parking garages

Ra narrow vehicle traveling in front, e.g. a

motorbike

Ra vehicle traveling in front on a different line

relative to the center of your vehicle

Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle.

Adaptive Brake Assist i Observe the "Important safety notes"

section (Y page 67). G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In such cases, Adaptive Brake Assist may: Rintervene unnecessarily Rnot intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. G WARNING Adaptive Brake Assist does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rto stationary obstacles Rwhen cornering As a result, Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.

Adaptive Brake Assist aids you in braking during hazardous situations at speeds above 4 mph (7 km/h) and uses the radar sensor system to evaluate the traffic situation. With the help of Adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. Should you approach an obstacle and Adaptive Brake Assist has detected a risk of collision, Adaptive Brake Assist calculates the braking force necessary to avoid a rear-end collision. Should you apply the brakes vigorously, Adaptive Brake Assist will

72 Driving safety systems

automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the

emergency braking situation is over. ABS prevents the wheels from locking.

The brakes will work normally again if: Ryou release the brake pedal Rthere is no longer any danger of a rear-end

collision

Rno obstacle is detected in front of your

vehicle

Adaptive Brake Assist is then deactivated. Up to vehicle speeds of around 155 mph (250 km/h), adaptive Brake Assist is capable of reacting to moving objects that have already been recognized as such at least once over the period of observation. Adaptive Brake Assist does not react to stationary obstacles. If Adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else

covering the sensors

Rsnow or heavy rain Rinterference by other radar sources Rthere are strong radar reflections, for

example in parking garages

Ra narrow vehicle traveling in front, e.g. a

motorbike

Ra vehicle traveling in front on a different line

relative to the center of your vehicle

Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle.

ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes"

section (Y page 67).

ESP® monitors driving stability and traction, i.e. power transmission between the tires and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking.

ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is transferred to the wheel or wheels with traction. Traction control remains active, even if you deactivate ESP®.

Important safety notes i Observe the "Important safety notes"

section (Y page 67). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop.

! Vehicles with 4MATIC: switch off the

ignition when the parking brake is being tested on a brake dynamometer.

Application of the brakes by ESP® may otherwise destroy the brake system.

off, ESP® remains deactivated when the engine is switched on again.

Vehicles without 4MATIC: observe the notes on ESP®(Y page 366) when towing the vehicle with a raised rear axle. ESP® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 289) and display messages which may be shown in the instrument cluster (Y page 258). i Only use wheels with the recommended

tire sizes. Only then will ESP® function properly.

Characteristics of ESP® General information If the ÷ ESP warning lamp goes out before beginning the journey, ESP® is automatically active. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. If ESP® intervenes: X Do not deactivate ESP® under any

circumstances.

X Only depress the accelerator pedal as far

as necessary when pulling away.

X Adapt your driving style to suit the

prevailing road and weather conditions.

ECO start/stop function The ECO start/stop function switches the engine off automatically when the vehicle stops moving. The engine starts automatically when the driver wants to pull away again. ESP® remains in its previously selected status. Example: if ESP® was deactivated before the engine was switched

Deactivating/activating ESP® (except AMG vehicles) Important safety notes You can select between the following statuses of ESP: RESP® is activated. RESP® is deactivated. G WARNING If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. Only deactivate ESP® in the situations described in the following.
