ing distance. Safety and Security Driving safety systems 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 the “Practical hints” section (컄 page 353). 85 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! 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. 86 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 capabili- ties of a BAS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others. The Electronic Stability Program (ESP®) 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 spin- ning or if the vehicle starts to skid. By ap- plying brakes to the appropriate wheel and by limiting engine output, the ESP® works to stabilize the vehicle. The ESP® is espe- cially useful while driving off and on wet or slippery road surfaces. The ABS/ESP® warning lamp v in the instrument cluster flashes when the ESP® is engaged. The ABS/ESP® warning lamp v in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running. Warning! Warning! Never switch off the ESP® when you see the ABS/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. 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 449). Safety and Security Driving safety systems For more information, see the “Practical hints” section (컄 page 353) and (컄 page 368). 87 Safety and Security Driving safety systems 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 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 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 88 The switch is located on the center con- sole. 1 ESP® switch 왘 Press ESP® switch 1 until the ABS/ESP® warning lamp v in the instrument cluster comes on. The ESP® is deactivated. 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 앫 you cannot activate Distronic* When the ESP® is switched off and one or more drive wheels are spinning, the ABS/ESP® warning lamp v in the speedometer flashes. However, the ESP® will then not stabilize the vehicle. Warning! Switching on the ESP® 왘 Press ESP® button 1. The ABS/ESP® warning lamp v in the instrument cluster goes out. You are now again in normal driving mode with ESP® switched on. When the ABS/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. Safety and Security Driving safety systems Electro-hydraulic brake system The electro-hydraulic brake system com- bines a hydraulic brake circuit with elec- tronically controlled brake servo assistance. You have increased braking safety and improved braking comfort. Warning! Never ignore a brake malfunction indicated in the speedometer display, for example by the ; (USA only) or 3 (Canada only) warning lamp. Refer to the “Practical hints” section (컄 page 354). Also read and ob- serve the messages in the multifunction dis- play (컄 page 363). 89 If there is a malfunction in the electro-hydraulic brake system, we recom- mend that the vehicle be transported with all wheels off the ground using flatbed or ap- propriate wheel lift/dolly equipment. A tow bar must be used if circumstances do not permit the use of the recommended towing methods and the vehicle requires towing with all four wheels on the ground. Towing the vehicle with all four wheels on the ground is only permissible for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). For more infor- mation, refer to “Towing the vehicle” (컄 page 437). The electro-hydraulic brake system is auto- matically activated when you 앫 unlock the vehicle with the SmartKey or the KEYLESS-GO* 앫 open the driver’s or passenger door 앫 turn the SmartKey in the starter switch to position 1 앫 in vehicles with KEYLESS-GO*, press the start/stop button on the gear selector lever once 앫 depress the brake pedal 앫 release the parking brake Safety and Security Driving safety systems Warning! The electro-hydraulic brake system requires electrical power to operate. A malfunction in the vehicle’s power supply or electrical system may impair brake sys- tem operation and switch it into its emer- gency operation mode. In such a case, the red brake warning lamp (컄 page 354) and warning messages in the instrument cluster (컄 page 363) come on while driving. To brake, the driver must then apply signifi- cantly greater brake pedal pressure and depress the pedal much further to obtain the expected braking effect. If necessary, apply full pressure to the brake pedal. Brakes may only be applied to the front wheels. Stopping distance is increased! 90 i If the electro-hydraulic brake system is activated as the brake pedal is first de- pressed, you may feel a reduced pedal resistance and longer pedal travel than normal. When releasing the pedal, you may also feel the brake pedal pulsate and you may hear a sound which is caused by the activation of the electro-hydraulic brake system pump. This is normal and not an indication of a malfunction. Pedal travel returns to normal when you release the brake pedal and the sound soon ceases. If you experience the above while driv- ing and the red brake warning lamp (컄 page 354) illuminates and/or warn- ing messages appear in the instrument cluster (컄 page 363), the brake system is malfunctioning. Follow the instruc- tions of the warning message(s) and have the brake system checked imme- diately. Warning! Have brake pad replacement and other work on the electro-hydraulic brake system car- ried out by qualified technicians only. Con- tact an authorized Mercedes-Benz Center for further information. The electro-hydrau- lic brake system must be deactivated prior to working on the system. High pressure is intermittently built up in the system as part of its automatic self-test. In addition, the system is automatically activated when the vehicle is unlocked by SmartKey, when the driver or passenger door is opened, when the starter switch is turned to position 1, when the brake pedal is depressed or when the parking brake is released. Failure to de- activate the system prior to maintenance will cause brake pistons to extend and brake fluid to leak, which may result in injuries (contusions and acid burns). Extended brake pistons may also cause injury. Safety and Security Driving safety systems The electro-hydraulic brake servo assis- tance switches off automatically 앫 approximately 2 minutes after you turned the SmartKey in the starter switch to position 0 or removed the SmartKey 앫 approximately 2 minutes after you pressed the KEYLESS-GO* start/stop button to turn off the engine or power supply and opened the driver’s door (with driver’s door open, the starter switch is set to position 0, same as SmartKey removed from starter switch) 앫 approximately 20 seconds after you locked the vehicle from outside 91 Safety and Security Driving safety systems Note on driving with the electro-hydraulic brake system 앫 Following extended periods of only minor loads to your brake system, you should occasionally apply the brakes when traveling at high speeds. This improves the grip of the brake pads. 앫 On long and steep grades, shift to a lower gear (gear range 1, 2, or 3) to prevent the brakes from overheating and to reduce brake wear. 앫 After hard braking, it is advisable to drive on for some time so that the air stream will cool down the brakes fast- er. Warning! 앫 Only Mercedes-Benz approved compo- nents (e.g. brake pads) should be installed on your vehicle. Brake pads not approved by Mercedes-Benz may impair the safety of your vehicle. Be very careful not to endanger other road users when you apply the brakes. 앫 After driving on wet or snow-covered roads, you should apply your brakes firmly before parking your vehicle. This produces heat which serves to dry the brake disks and help prevent corro- sion. 92 왔 Anti-theft systems Immobilizer Deactivating Anti-theft alarm system Safety and Security Anti-theft systems The immobilizer prevents unauthorized persons from starting your vehicle.
