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) 앫 4MATIC (Four Wheel Electronic

Traction System)

In winter operation, the maximum effectiveness of the ABS, ESP®, and 4MATIC (if so equipped) is only achieved with winter tires (컄 page 336), or snow chains as re- quired.

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, ESP®, and 4MATIC (if so equipped) 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 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 350) and (컄 page 360).

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 afforded. The BAS cannot prevent accidents, includ- ing 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.

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 speedometer flashes when the ESP® is engaged. The ESP® warning lamp v in the speedometer 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 speedometer. 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.

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.

The ESP® will only function properly if you use wheels of the recommended tire size (컄 page 432).

90

Vehicles without 4MATIC: Because of the ESP®’s automatic operation, 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 92).

For more information, see “Practical hints” (컄 page 354) and (컄 page 360).

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 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

! 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 speed- ometer flashes. However, the ESP® will then not stabilize the vehicle.

Safety and Security Driving safety systems

The switch is located on the upper part of the center console.

Warning!

1 ESP® switch (off/on) 왘 With the engine running, press

switch 1. The ESP® warning lamp v in the speedometer 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 ESP® switch 1.

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

91

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 speedometer, proceed as fol- lows: 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

92

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 con- ducted on a two-axle dynamometer. Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty.

Because of the ESP®’s automatic operation, 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 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.

At highly demanding operating condi- tions, 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 functioning normally.

왔 Anti-theft systems Immobilizer
