Safety and Security Occupant safety

Warning!

If the 1 indicator lamp and the 56 indicator lamp are lit at the same time, there is a malfunction in the Occupant Classification System. The front passenger front air bag will be deactivated in this case.

In order to ensure proper operation of the air bag system and OCS: 앫 Have the system checked as soon as

possible by qualified technicians. Contact an authorized Mercedes-Benz Center.

앫 Sit properly belted in a nearly upright

position with your back against the seat backrest.

앫 Do not lean on the armrests or lift your- self from the seat by using the handle over the door as this may cause the OCS to be unable to correctly approximate the occupant weight category.

82

앫 Only have the seat repaired or replaced

by an authorized Mercedes-Benz Center.

앫 Read and observe all warnings in this

chapter.

Self-test Occupant Classification System After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO* start/stop button once or twice, the 56 indicator lamp located in the center console illuminates. If an adult occupant is properly sitting on the front passenger seat and the system senses the occupant as being an adult, the 56 indicator lamp will illuminate and go out after approximately six seconds. If the seat is not occupied and the system senses the front passenger seat as being empty, the 56 indicator lamp will illuminate and not go out.

Warning!

If the 56 indicator lamp should not illuminate, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat.

More information can be found in the “Practical hints” section (컄 page 381).

Warning!

Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the Occupant Classifi- cation System. The bottom of the child seat must make full contact with the passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protec- tion for the child.

Follow the manufacturer’s instructions for installation of child seats.

Child seat anchors – LATCH type This vehicle is equipped with two LATCH (Lower Anchors and Tethers for CHildren) type anchors (at each of the rear seats) for the installation of a LATCH-type child seat with matching mounting fittings. Depending on vehicle production date, your vehicle is equipped with either LATCH-type design A or B.

Your cabriolet does not have and is not required to have anchorage rings for a child seat’s top tether strap in the rear seating positions. Child seats can be used with the seat belt, or lower anchor system and seat belt, fully in accor- dance with the child seat manufactur- er’s instructions.

Warning!

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 belt positioning for children from 41 lbs until they reach a height where a lap/shoulder belt fits properly without a booster.

Install child seat according to manufactur- er’s instructions.

The child seat must be firmly attached in the right and left side anchor 2. An incorrectly mounted child seat may come loose during an accident which could result in serious injury or death to the child.

Damaged or impact damaged child seats or child seat anchor fittings must be replaced.

Do not leave children unattended in the vehicle, even if the children are secured in a child restraint system.

Safety and Security Occupant safety

The child seat must be firmly attached in the right and left side anchor 2.

Non-LATCH type child seats may also be used and can be installed using the vehicle’s seat belt system (컄 page 69). Install child seat according to the manufacturer’s instructions.

왔 Driving safety systems In this section you will find information on the following driving safety systems: 앫 ABS (Antilock Brake System) 앫 BAS (Brake Assist System) 앫 ESP® (Electronic Stability Program)

In winter operation, the maximum ef- fectiveness of the ABS, the BAS, and the ESP® is only achieved with winter tires (컄 page 359) or snow chains as required.

Safety and Security Driving safety systems

Warning!

ABS

The following factors increase the risk of accidents: 앫 Excessive speed, especially in turns 앫 Wet and slippery road surfaces 앫 Following another vehicle too closely The ABS, BAS, and ESP® cannot reduce this risk.

Always adjust your driving style to the prevailing road and weather conditions.

Warning!

Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pump- ing 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 ap- proximately 5 mph (8 km/h) independent of road surface conditions. On slippery road surfaces, the ABS will respond even to light brake pressure. The - indicator lamp in the instrument cluster (컄 page 24) comes on when you switch on the ignition. It goes out when the engine is running.

87

Safety and Security Driving safety systems

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

brake pedal while experiencing 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.

88

Emergency brake maneuver 왘 Keep continuous full pressure on the

brake pedal.

Warning!

The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction af- forded. The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning. Only a safe, atten- tive, and skillful driver can prevent acci- dents. The capabilities of an ABS equipped vehicle must never be exploited in a reck- less or dangerous manner which could jeop- ardize the user’s safety or the safety of others.

For more information, see “Practical hints” (컄 page 373).

BAS

The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby poten- tially reducing the braking distance. 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.

Warning!

If the BAS is malfunctioning, the brake sys- tem is still functioning normally, but without the additional brake boost available that BAS would normally provide in an emergen- cy braking maneuver. Therefore, the braking distance may increase.

Warning!

ESP®

The BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction. The BAS cannot prevent accidents, including those resulting from excessive speed in turns, fol- lowing another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a BAS equipped vehicle must never be exploited in a reckless or danger- ous manner which could jeopardize the user’s safety or the safety of others.

For more information, see “Practical hints” (컄 page 373).

The Electronic Stability Program (ESP®) is operational as soon as the engine is run- ning and monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling. The ESP® recognizes when a wheel is spinning or if the vehicle starts to skid. By applying brakes to the appropriate wheel and by limiting the engine output, the ESP® works to stabilize the vehicle. The ESP® is especially useful while driving off and on wet or slippery road surfaces. The ESP® also stabilizes the vehicle during braking maneuvers. The ESP® warning lamp v in the instru- ment cluster flashes when the ESP® is engaged. The warning lamp v in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.

Safety and Security Driving safety systems

Warning!

Never switch off the ESP® when you see the ESP® warning lamp v flashing in the in- strument cluster. In this case, proceed as follows: 앫 While driving off, apply as little throttle

as possible.

앫 While driving, ease upon the accelera-

tor.

앫 Adapt your speed and driving style to

the prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The ESP® cannot prevent accidents result- ing from excessive speed.

89

Safety and Security Driving safety systems

Warning!

The ESP® cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded. The ESP® cannot prevent accidents, including those resulting from excessive speed in turns or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP® equipped vehicle must never be exploited in a reckless or dan- gerous manner which could jeopardize the user’s safety or the safety of others.

90

Because of the ESP®’s automatic operation, the engine must be shut off when 앫 the parking brake is being tested on

a brake test dynamometer

앫 the vehicle is being towed with the

front axle raised

Active braking action through the ESP® may otherwise seriously damage the brake system.

The ESP® will only function properly if you use wheels of the recommended tire size.

For more information, see “Practical hints” (컄 page 373).

Switching off the ESP®

Warning!

The ESP® should not be switched off during normal driving other than in the circum- stances described below. Disabling of the system will reduce vehicle stability in stan- dard driving maneuvers. Do not switch off the ESP® when a Minis- pare or collapsible tire is mounted.

To improve the vehicle's traction, turn off the ESP® in driving situations where it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: 앫 when driving with snow chains 앫 in deep snow 앫 in sand or gravel

! Turn on the ESP® immediately if the aforementioned circumstances do not apply anymore.

When you switch off the ESP® 앫 the ESP® does not stabilize the vehicle 앫 the engine output is not limited, which

allows the drive wheels to spin and thus cut into surfaces for better grip 앫 the traction control will still brake a

spinning wheel

앫 the ESP® continues to operate when

you are braking

When the ESP® is switched off and one or more drive wheels are spinning, the ESP® warning lamp v in the instru- ment cluster flashes. However, the ESP® will then not stabilize the vehicle.

Safety and Security Driving safety systems

The switch is located on the center con- sole.

Warning!

1 ESP® switch (off/on) 왘 Press switch 1.

The ESP® warning lamp v in the in- strument cluster comes on. The ESP® is deactivated.

When the ESP® warning lamp v is illuminated continuously, the ESP® is switched off.

Adapt your speed and driving to the prevail- ing road conditions and to the non-operating status of the ESP®.

Avoid spinning of a drive wheel for an extended period with the ESP® switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

Switching on the ESP® 왘 Press switch 1 again.

The ESP® warning lamp v in the in- strument cluster goes out. You are now again in normal driving mode with ESP® switched on.
