2013 Mercedes-benz CL Class Owners Manual

For more information, see "Problems with the Occupant Classification System" (Y page 54). G WARNING Never place anything between seat cushion and child seat (e.g. a pillow), since it reduces the effectiveness of the OCS. The underside and rear side child restraint system must be placed entirely on the seat cushion and the backrest of the front-passenger seat backrest. If necessary, adjust the tilt of the passenger seat backrest. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protection for the child. Follow the manufacturer's instructions for installation of child restraint systems.

If the SmartKey has been removed from the ignition lock or is in position 0, 42 indicator lamp : does not light up. G WARNING If the red SRS 6 indicator lamp in the instrument cluster and the 42
indicator lamp are lit at the same time, there is a malfunction in the OCS. The front passenger front air bag will be deactivated in this case. Have the system checked by qualified technicians as soon as possible. Contact an authorized Mercedes-Benz Center. Only have the seat repaired or replaced at an authorized Mercedes-Benz Center. In order to ensure proper operation of the air bag system and OCS: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RWhen seated, a passenger should not

position him/herself in such a way as to cause the passenger's weight to be lifted from the seat cushion as this may result in the OCS being unable to correctly approximate the passenger's weight category.

RRead and observe all warnings in this

chapter.

54 Occupant safety

Problems with the Occupant Classification System

Possible causes/consequences and M Solutions The OCS is malfunctioning. X Have the OCS checked as soon as possible at an authorized

Mercedes-Benz Center.

X Observe the additional display messages in the multifunction

display (Y page 364).

Problem The 42
indicator lamp illuminates and remains illuminated. The person on the front-passenger seat: Rhas the weight of a

typical adult

Rhas been determined by the system not to be a child

G WARNING If the 42 indicator lamp illuminates and remains illuminated when the weight of a typical adult or someone larger than a small individual has been detected on the passenger seat, the system then determines the occupant cannot be a child. Do not allow any occupant to use the passenger seat until the system has been repaired.

Problem The 42
indicator lamp does not illuminate and/or does not remain illuminated. The front-passenger seat is: Runoccupied Roccupied with a

weight up to that of a typical twelve- month-old child in a standard child restraint system

Possible causes/consequences and M Solutions The OCS is malfunctioning. X Make sure there is nothing between the seat cushion and the

child seat.

X Check the installation of the child restraint system. X Make sure that no objects are applying additional weight onto

the seat.

X If the 42 indicator lamp does not illuminate, have

the OCS checked as soon as possible at an authorized Mercedes-Benz Center. Do not transport a child on the front- passenger seat as long as the OCS is not functioning.

X Observe the additional display messages in the multifunction

display (Y page 364).

G WARNING If the 42 indicator lamp does not illuminate or remains out with the weight of a typical 12-month-old child in a standard child restraint or less, or is unoccupied, on the front- passenger seat, do not transport a child on the front-passenger seat until the system has been repaired.

PRE-SAFE® (anticipatory occupant protection system) G WARNING The PRE-SAFE® system reduces the impact of an accident on vehicle occupants, as long as their seat belts have been fastened correctly. Although your vehicle is equipped with a PRE- SAFE® system, the possibility of injury in the event of an accident cannot be ruled out. You should therefore always drive carefully and adapt your driving style to the prevailing road, weather and traffic conditions.

PRE-SAFE® takes preemptive measures to protect occupants in certain hazardous situations. PRE-SAFE® intervenes: Rif BAS PLUS intervenes powerfully on

vehicles with DISTRONIC PLUS

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-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 side windows and sliding sunroof are closed so that only a small gap remains.

If the hazardous situation passes without resulting in an accident: Rthe air pressure in the side bolsters of the active multicontour seat is reduced again. Rall settings made by PRE-SAFE® can then

be reversed.

If the seat belts are not released: X Move the backrest back slightly, but only

when the vehicle is stationary. The belt pretensioning is reduced and the locking mechanism is released. G WARNING Make sure that nobody can become trapped as you adjust the seat.

! 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.

Seat belts Important safety notes The use of seat belts and infant and child restraint systems is required by law in all 50
states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened when the vehicle is in motion. i For further information on infants and children traveling in the vehicle and on infant and child restraint systems, see "Children in the vehicle" (Y page 59). G WARNING Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.

56 Occupant safety

In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. G WARNING Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. G WARNING Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time. G WARNING Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced and their anchoring points must also be checked. Only use seat belts which have been approved by Mercedes-Benz. Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary. Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center.

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, 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. G WARNING Do not pass seat belts over sharp edges. They could tear. Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism. This could damage the seat belt.

Never attempt to make modifications to seat belts. This could impair the effectiveness of the seat belts.

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.

section of the seat belt across the middle of your shoulder and the lap section across your hips.

X Engage belt tongue ; in buckle =. X If necessary, pull upwards on the shoulder section of the seat belt to tighten the belt across your body.

All seat belts except the driver's seat belt are equipped with a special seat belt retractor to securely fasten child restraint systems in the vehicle. For further information about special seat belt retractors, see (Y page 61). For more information about releasing the seat belt with release button ?, see "Releasing seat belts" (Y page 58).

Releasing seat belts X Press release button ?(Y page 57) and guide belt tongue ; back towards belt sash guide :.

! Make sure that the seat belt is fully rolled up. Otherwise, the seat belt or belt tongue will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Damaged seat belts can no longer fulfill their protective function and must be replaced. Visit a qualified specialist workshop.

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 will light up for six seconds each time the engine is started. It then goes out if the driver and the front passenger have fastened their seat belts.

If the driver's seat belt is not fastened when the engine is started, an additional warning tone will sound. The warning tone goes out after approximately six seconds or once the driver's seat belt is fastened. If after six seconds the driver's or front- passenger seat belt is not fastened and the doors are closed, the 7 seat belt warning lamp will remain lit: Runtil the driver's or front passenger's seat

belt is fastened

Ronce the vehicle has exceeded a speed of 15 mph (25 km/h), in addition a warning tone will sound with increasing intensity for up to 60 seconds or until the driver's or front-passenger seat belt is fastened.

If the driver or front passenger unfastens their seat belt during the journey, the 7 seat belt warning lamp lights up and the warning tone sounds again. The warning tone ceases after 60 seconds even if the driver or front passenger has still not fastened their seat belt. The 7 seat belt warning lamp stops flashing, but remains lit. After the vehicle has come to a stop, the warning tone will be reactivated and the 7 seat belt warning lamp will flash again once the vehicle has exceeded a speed of 15 mph (25 km/h). The 7 seat belt warning lamp will not go out until: 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 belt" (Y page 389).

Emergency Tensioning Devices, seat belt force limiters The seat belts are equipped with ETDs 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. Seat belt force limiters, when triggered, help to reduce the peak force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags. These take on a part of the deceleration force. Thus, the force exerted on the occupant is distributed over a greater area. The ETDs can only be activated when: Rthe ignition is switched on. Rthe restraint systems are operational; see

"SRS warning lamp" (Y page 44).

Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front. Rthe front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side.

The ETDs on the 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: Rif, in the event of a head-on or rear-end

collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact

Rif, in the event of a side impact, on the side

opposite the impact the vehicle decelerates or accelerates rapidly in a lateral direction

Rif, in certain situations where the vehicle overturns, the system determines that it can provide additional protection

If the air bags 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. The 6 SRS warning lamp lights up. 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.

! 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.

Automatic comfort-fit feature The front seat belts have an automatic comfort-install feature. The automatic comfort-install feature reduces the retraction force of the seat belts. This results in increased seat belt comfort.

Children in the vehicle Child restraint systems Important safety notes We recommend that all infants and children be properly secured in an infant or child restraint system at all times while the vehicle is in motion. The use of seat belts and infant and child restraint systems is required by law in all 50
states, the District of Columbia, the U.S. territories and all 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

60

Children in the vehicle

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 comply with U.S. Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. An information label on the child restraint system indicates whether it meets these standards. This information is also provided in the installation instructions supplied 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 all warning signs in the vehicle interior and on the infant or child restraint. 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 seats 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. The infant or child restraint system 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 appropriate 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 eliminate this risk completely is never to place a child in a rear-facing child restraint in the front- passenger seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint on the rear seat.

RIf you install a rear-facing child restraint on

the front-passenger seat, 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 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

- secure child restraint with the vehicle's

seat belt according to the child seat manufacturer's instructions

RFor children larger than a typical 12-month- old child, the front-passenger front air bag can be activated or deactivated. 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. 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 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.

If an infant or child is traveling in the vehicle: X Secure the infant or child with an

appropriate infant or child restraint recommended for the child's age and weight.

X Make sure that the infant or child is

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

Driving safety systems Overview of driving safety systems In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System) RBAS (Brake Assist System) RBAS PLUS (Brake Assist System Plus) RESP® (Electronic Stability Program) REBD (Electronic Brake force Distribution) RADAPTIVE BRAKE RPRE-SAFE® Brake

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 and weather 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. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 454). 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) Important safety notes i Observe the "Important safety notes"

section (Y page 64). 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 391) and

Driving safety systems

65

display messages which may be shown in the instrument cluster (Y page 353). 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. ABS works from a speed of about 5 mph (8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery surfaces, even if you only brake gently. The ! warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.

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) i Observe the "Important safety notes"

section (Y page 64). 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.

BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance.

66 Driving safety systems

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

BAS PLUS (Brake Assist System PLUS) BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS. i Observe the "Important safety notes"

section (Y page 64).

BAS PLUS provides braking assistance in hazardous situations at speeds greater than 4 mph (7 km/h) and uses radar sensor technology to assess the traffic situation. With the help of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. At speeds up to 40 mph (70 km/h), BAS PLUS may also detect stationary obstacles, for example stopped or parked vehicles. Should you approach an obstacle and BAS PLUS has detected a risk of collision, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. RWhen 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.

RWhen driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. Braking is performed as late as possible.

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.

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

BAS PLUS is then deactivated. For BAS PLUS to assist you, the radar sensor system must be operational. G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In these cases, Adaptive Brake Assist may not intervene. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.

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

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

section (Y page 64). 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.

Vehicles without 4MATIC: when towing your vehicle with the rear axle raised, it is important that you observe the notes on ESP®(Y page 448). 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 393) and display messages which may be shown in the instrument cluster (Y page 353).

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. 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.

i Only use wheels with the recommended

tire sizes. Only then will ESP® function properly.

ETS/4ETS (Electronic Traction System) 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. On vehicles with 4MATIC, more drive torque is also transferred to the wheel or wheels with traction. Traction control remains active if you deactivate ESP®.

Deactivating/activating ESP® i Observe the "Important safety notes"

section (Y page 64). 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.

! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.

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

X To deactivate:(Y page 348).

The å ESP® OFF warning lamp in the instrument cluster lights up. CL 63 AMG: deactivate ESP® when driving on designated roads when the vehicle's own oversteering and understeering characteristics are desired. Driving without ESP® requires an extremely qualified and experienced driver who is able to cope with these critical driving conditions.

X To activate:(Y page 348).

The å ESP® OFF warning lamp in the instrument cluster goes out.

ESP® is activated automatically when the engine is started. If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle. It may be best to deactivate ESP® in the following situations: Rwhen using snow chains Rin deep snow Ron sand or gravel If you deactivate ESP®: RESP® no longer improves driving stability. Rtraction control is still activated. RESP® still provides support when you

brake.

Rthe engine's torque is no longer limited, and the drive wheels can spin. The spinning of the wheels results in a cutting action, which provides better grip.

Vehicles with ECO start/stop function: the ECO start/stop function switches the engine off automatically when the vehicle comes to a stop. 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

EBD (electronic brake force distribution) i Observe the "Important safety notes"

section (Y page 64). G WARNING If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop.

Observe information regarding indicator and warning lamps (Y page 391) as well as display messages (Y page 357). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.

ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 308) and hill start assist (Y page 275).

PRE-SAFE® Brake i Observe the "Important safety notes"

section (Y page 64).

PRE-SAFE® Brake is only available in vehicles with DISTRONIC PLUS. PRE-SAFE® Brake can help you to minimize the risk of a collision with a vehicle ahead or reduce the effects of such a collision. If PRE- SAFE® Brake has detected a risk of collision,

you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. Starting at a speed of around 4 mph (7 km/h), this 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.

From a speed of approximately 4 mph (7 km/h), if the driver and front passenger have fastened their seat belts, PRE-SAFE® Brake can brake the vehicle automatically at speeds up to approximately 124 mph (200 km/h). Due to the nature of the system, particularly complicated driving conditions may cause unnecessary warnings or the unnecessary intervention of PRE-SAFE® Brake. You can prevent the intervention of the PRE- SAFE® Brake at any time by: Rdepressing the accelerator pedal further. Ractivating kickdown. Rreleasing the brake pedal. The braking action of PRE-SAFE® Brake is ended automatically if: Ryou maneuver to avoid the obstacle. Rthere is no longer any danger of a rear-end

collision.

Rthere is no longer an obstacle detected in

front of your vehicle.

With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. At speeds up to approximately 40 mph (70 km/h), PRE-SAFE® Brake can

Driving safety systems

69

also detect stationary obstacles such as stopped or parked vehicles. If you approach an obstacle and PRE-SAFE® Brake detects a risk of collision, the system will initially alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventative passenger protection measures (PRE-SAFE®) are activated (Y page 55). If a risk of collision remains at speeds of over 20 mph (30 km/h) and you do not brake, take evasive action or significantly accelerate, automatic emergency braking may be performed up to and including full brake application. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided. G WARNING PRE-SAFE® Brake will initially brake your vehicle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you also brake. Automatic emergency braking cannot prevent a collision. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then

brake the vehicle

Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation.

Theft deterrent locking system

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 G WARNING PRE-SAFE® Brake does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering As a result, PRE-SAFE® Brake may neither give warnings nor 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 order to maintain an appropriate distance from the vehicle in front and thus prevent a collision, you must apply the brakes yourself. X To activate/deactivate: activate or

deactivate PRE-SAFE® Brake in the on- board computer (Y page 348). After activation, the Ä symbol is displayed on the left in the instrument cluster.

For BAS PLUS to assist you, the radar sensor system must be operational. 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.
