For ESP warning message, see page 273. With the ABS malfunctioning, the ESP is also switched off. Driving the vehicle with varied size tires will cause the wheels to rotate at different speeds, therefore the ESP may activate (yellow ESP warning lamp in speedometer dial comes on). For this reason, all wheels, including the spare wheel, must have the same tire size. When testing the parking brake on a brake test dynamometer, the engine must be shut off. Otherwise, the ESP will immediately be engaged and will apply the rear wheel brakes. In winter operation, the maximum effectiveness of the ESP is only achieved with Mercedes-Benz recommended M+S rated radial-ply tires and/or snow chains. Synchronizing ESP If the power supply was interrupted (battery disconnected or empty), the ESP warning message may be displayed with the engine running. Turn steering wheel completely to the left and then to the right. The ESP warning message should go out. Driving systems Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index 261 Instruments and controls Driving systems Operation Driving Instrument cluster display Practical hints Car care Technical data Index ESP control switch P42.45-2245-26 ESP control switch located on center console. 1 Press to switch ESP off ESP warning lamp v in located in speedometer dial comes on. 2 Press to switch ESP on ESP warning lamp v in located in speedometer dial goes out. 262 To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand or gravel, switch off ESP by pressing the upper half (1) of the ESP switch. The ESP warning lamp v located in the speedometer dial, is continuously illuminated. Warning! When the ESP warning lamp is illuminated continuously, the ESP is switched off. Adapt your speed and driving to the prevailing road conditions. With the ESP system switched off, the engine torque reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ESP is unavailable. Adapt your speed and driving to the prevailing road conditions. A portion of the ESP system remains active, even with the switch in the OFF position. If one drive wheel loses traction and begins to spin, the brake is applied until the wheel regains sufficient traction. The traction control engages at vehicle speeds up to approximately 24 mph (40 km/h), and switches off at 50 mph (80 km/h). Notes: Avoid spinning of one drive wheel. This may cause serious damage to the drive train which is not covered by the Mercedes-Benz Limited Warranty. The ESP warning lamp, located in the speedometer dial, starts to flash at any vehicle speed as soon as the tires lose traction and the wheels begin to spin. To return to the enhanced vehicle stability offered by ESP: press lower half (2) of the switch (the ESP warning lamp in the speedometer dial goes out). Important! If the ESP warning lamp flashes: • During take-off, apply as little throttle as possible. • While driving, ease up on the accelerator.

Emission control Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits required by law. These systems, of course, will function properly only when maintained strictly according to factory specifications. Any adjustments on the engine should, therefore, be carried out only by authorized Mercedes-Benz Center qualified technicians. Engine adjustments should not be altered in any way. Moreover, the specified service jobs must be carried out regularly according to Mercedes-Benz servicing requirements. For details refer to the Service Booklet. Warning! Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and inhaling it can cause unconsciousness and lead to death. Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one window fully open. On-board diagnostic system Check engine malfunction indicator lamp Engine malfunction indicator lamp. If the “CHECK ENGINE” malfunction indicator lamp comes on when the engine is running, it indicates a malfunction of the fuel management system, emission control system, systems which impact emissions, or the fuel cap is not closed tight (check the fuel cap). If the “CHECK ENGINE” lamp is illuminated continuously and the vehicle is driving normally, you may still drive the vehicle, however, in all cases, we recommend that you have the system checked at your authorized Mercedes-Benz Center as soon as possible. If the “CHECK ENGINE” lamp is flashing and/or the vehicle is not driving normally (e.g. malfunction of the fuel management system or running out of fuel), serious damage can occur to the emission system. Please contact your authorized Mercedes-Benz Center immediately. The Sequential Multiport Fuel Injection (SFI) control module monitors emission control components that either provide input signals to or receive output signals from the control module. Malfunctions resulting from interruptions or failure of any of these components are indicated by the “CHECK ENGINE” malfunction indicator lamp in the instrument cluster and are simultaneously stored in the SFI control module. If the “CHECK ENGINE” malfunction indicator lamp comes on, have the system checked at your authorized Mercedes-Benz Center as soon as possible. With some exceptions, the control module switches off the “CHECK ENGINE” malfunction indicator lamp if the condition, causing the lamp to come on, no longer exists during three consecutive cycles. An on-board diagnostic connector is located in the passenger compartment near to the parking brake pedal, allowing the accurate identification of system malfunctions through the readout of diagnostic trouble codes. Malfunction and indicator lamps 269 Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Malfunction and indicator lamps 270 Brake warning lamp Except Canada Canada only When the brake warning lamp and message appear while the engine is running, this means: • there is insufficient brake fluid in the reservoir (engine running and parking brake released), or • the parking brake is set (engine running). Warning! Driving with the brake warning lamp illuminated can result in an accident. Have your brake system checked immediately if the brake warning lamp stays on. Don’t add brake fluid before checking the brake system. Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned. Note: If you find that the minimum mark on the brake fluid reservoir is reached, have the brake system checked for brake pad thickness and leaks. Supplemental restraint system (SRS) indicator lamp Fuel reserve warning The operational readiness of the airbag system is verified by the indicator lamp “SRS” in the instrument cluster when turning the electronic key in starter switch to position 1 or 2. If no fault is detected, the lamp will go out after approximately 4 seconds; after the lamp goes out, the system continues to monitor the components and circuitry of the airbag system and will indicate a malfunction by coming on again. Warning! In the event a malfunction of the “SRS” is indicated as outlined above, the “SRS” may not be operational. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the “SRS” may not be activated when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unnecessarily which could also result in injury. See page 65 for notes on airbags, see page 63 for belt tensioners and page 55 for infant and child seat restraint. P54.30-3609-26 1 Fuel reserve indicator When the warning lamp (1) comes on after starting the engine, or if comes on while driving, it indicates that the fuel level is down to the reserve quantity of approximately 2.1 US gal (8 liters). See page 264 for notes on refueling the vehicle. Malfunction and indicator lamps 271 Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Malfunction and indicator lamps 272 ABS malfunction indicator lamp ABS The ABS malfunction indicator lamp in the instrument cluster comes on with the electronic key in starter switch position 2 and should go out with the engine running. When the ABS malfunction indicator lamp symbol and warning in the instrument cluster remains illuminated while the engine is running, it indicates that the ABS has detected a malfunction and has switched off. In this case, the brake system functions in the usual manner, but without antilock assistance. A malfunctioning ABS control unit can possibly affect the operation of other systems (e.g. Navigation, Automatic transmission). Be guided accordingly with respect to the use of those systems and have the system checked at your authorized Mercedes-Benz Center as soon as possible. With the ABS malfunctioning, the BAS and ESP are also switched off. The malfunction indicator lamps and malfunction messages in the multifunction display come on with the engine running. If the charging voltage falls below 10 volts, the malfunction indicator lamp comes on and the ABS is switched off. When the voltage is above this value again, the malfunction indicator lamp should go out and the ABS is operational. Have the system checked at your authorized Mercedes-Benz Center as soon as possible. See page 258 for notes on antilock brake system (ABS). Malfunction and indicator lamp in the center console AIRBAG OFF indicator lamp The ü indicator lamp will light up for approximately 6 seconds when you turn the electronic key in starter switch to position 1 or 2. It does not light up if there is a fault in the system. The ü indicator lamp stays lit as long as a Baby SmartTM child seat is properly installed on the front passenger seat. It indicates that the front passenger airbag is switched off. See page 62 for BabySmartTM airbag and its deactivation system. Electronic stability program (ESP) — warning lamp The yellow ESP warning lamp in the speedometer dial comes on with the electronic key in starter switch position 2. It should go out with engine running. If the ESP malfunction indicator lamp remains illuminated with the engine running, a malfunction has been detected in the system. Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. See electronic stability program (ESP) on page 260 if the warning lamp lights up or flashes when the vehicle is moving. Seat belt nonusage warning lamp With the electronic key in starter switch position 2, the seat belt nonusage warning lamp comes on, and a warning sounds for a short time if the drivers seat belt is not fastened. After starting the engine, the seat belt nonusage warning lamp blinks for a brief period to remind the driver and passengers to fasten seat belts.

The first aid kit is located in the storage space (1) in the shelf below the rear window. Lift cover. Remove first aid kit. Fuses Most of your vehicle’s electrical components are fused with safety fuses. With the exception of the brake lights, all individual lighting system components are electronically fused. Before replacing a blown safety fuse, determine the cause of the short circuit. Always observe amperage and color of fuse. The circuit for components is protected by a cycled circuit breaker interrupted if too much current is being drawn. The circuit closes automatically after a short time; the circuit is broken again if the malfunction reoccurs. Always use a new fuse for replacement. Never attempt to repair or bridge a blown fuse.
