2007 Mercedes-benz C Class Owners Manual

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) 앫 4MATIC (Four Wheel Electronic

Traction System)

82

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, ESP®, and 4MATIC (if so equipped) cannot reduce this risk.

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

i In winter operation, the maximum effectiveness of the ABS, ESP®, and 4MATIC (if so equipped) is only achieved with winter tires (컄 page 308), or snow chains as required.

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 approximately 5 mph (8 km/h) indepen- dent 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.

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 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.

brake pedal.

Warning!

When the ABS is malfunctioning, the BAS and the ESP® are also switched off. The ba- sic driving and braking functions are still available

When the ABS is malfunctioning, the wheels may lock during hard braking, reducing steering capability and extending the brak- ing distance.

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 avail- able on the road surface. The ABS cannot prevent accidents, including those resulting from excessive speed in turns, following an- other vehicle too closely, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ABS equipped vehicle must never be exploit- ed in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

For more information, see the “Practical hints” section (컄 page 322).

83

Warning!

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.

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, following another vehicle too closely, or hydroplaning. 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.

Safety and Security Driving safety systems

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. 왘 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!

Warning!

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

as possible.

앫 While driving, ease up on 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.

The ESP® cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by the exist- ing road and tire conditions. 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.

ESP®

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 the 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 and steering maneuvers. The ESP® warning lamp v in the instrument cluster flashes when the ESP® is engaged. The ESP® warning lamp v in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.

85

Safety and Security Driving safety systems

! Vehicles without 4MATIC: Because the ESP® operates automatically, the engine must be turned off (SmartKey in starter switch position 0 or 1) 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. For information on vehicles with 4MATIC, see “Four wheel electronic traction system (4MATIC) with the ESP® ” (컄 page 88).

i The ESP® will only function properly if you use wheels of the recommended tire size (컄 page 403). For more information, see the “Practical hints” section (컄 page 327) and (컄 page 335).

Electronic traction system The electronic traction system is a component of ESP®. The electronic traction system improves the vehicle’s ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. When you switch off the ESP®, the electronic traction system is still enabled.

Warning!

If you are driving too fast, the electronic traction system cannot reduce the risk of an accident.

The electronic traction system cannot pre- vent the natural laws of physics from acting on the vehicle.

86

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 Minispare wheel 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

! Switch 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 apply the

brakes to a spinning wheel

앫 the ESP® continues to operate when

you are braking

앫 you cannot activate the cruise control 앫 the cruise control switches off if

currently activated

i When the ESP® is switched off and one or more drive wheels are spinning, the ESP® warn- ing lamp v in the instrument cluster flashes. However, the ESP® will then not stabilize the ve- hicle.

Safety and Security Driving safety systems

The ESP® switch is located on the center console.

Warning!

1 ESP® switch 왘 With the engine running, press ESP®

switch 1 until the ESP® warning lamp v in the instrument cluster comes on. The ESP® is switched off.

When the ESP® warning lamp v is illuminated continuously, the ESP® is switched off or is not operational due to a malfunction. Vehicle stability in standard driving maneuvers reduces.

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 ESP® switch 1 until the ESP® warning lamp v in the instrument cluster goes out. You are now again in normal driving mode with ESP® switched on.

87

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

! Do not tow with one axle raised. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

! Performance testing must only be conduct- ed on a two-axle dynamometer. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

! Because the ESP® operates automatically, the engine must be shut off (SmartKey in starter switch position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Active braking action through the ESP® may otherwise seriously damage the front or rear axle brake system. Operational tests with the engine running can only be conducted on a two-axle dynamometer.

i At highly demanding operating conditions, the electronic traction system may temporarily switch off to prevent overheating of the drive wheel brakes. The message unavailable See Operator’s Manual will then appear in the multifunction display while the ESP® warning lamp v is flashing. The ESP® is still function- ing normally.

Safety and Security Driving safety systems

Four wheel electronic traction system (4MATIC) with the ESP®

Models with all-wheel-drive only. The 4MATIC improves vehicle’s ability to use available traction, e.g. during winter operation in mountains under snowy conditions, by applying power to all four wheels.

Warning!

If you see the ESP® warning lamp v flashing in the instrument cluster, proceed as follows: 앫 While driving off, apply as little throttle

as possible

앫 While driving, ease up on the accelera-

tor

Tachometer

Outside temperature indicator

The red marking on the tachometer (컄 page 24) denotes excessive engine speed.

! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warran- ty.

To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking.

Warning!

The outside temperature indicator is not de- signed to serve as an ice-warning device and is therefore unsuitable for that purpose.

Indicated temperatures just above the freez- ing point do not guarantee that the road sur- face is free of ice. The road may still be icy, especially in wooded areas or on bridges.

The outside temperature is indicated in the multifunction display (컄 page 121).

The temperature sensor is located in the front bumper area. Due to its location, the sensor can be affected by road or engine heat during idling or slow driving. There- fore, the accuracy of the displayed temper- ature can only be verified by comparison to a thermometer placed next to the sensor, not by comparison to external displays (e.g. bank signs, etc.). When moving the vehicle into colder ambi- ent temperatures (e.g. when leaving your garage), you will notice a delay before the lower temperature is displayed. A delay also occurs when ambient temper- atures rise. This prevents inaccurate tem- perature indications caused by heat radiated from the engine during idling or slow driving.
