Notes: The yellow ESP warning lamp v in the speedometer dial comes on with the electronic key in starter switch position 2. It should go out with the engine running. If the ESP warning message is displayed, a malfunction has been detected in the system. Only partial engine output will be available. Have the ESP checked at your authorized Mercedes-Benz Center as soon as possible. For ESP warning message, see page 303. 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.

272

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.

ESP control switch

ESP control switch located on center console.

1 Press to switch ESP off

ESP warning lamp v, located in speedometer dial, comes on.

2 Press to switch ESP on

ESP warning lamp v, located in speedometer dial, goes out.

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).

Raised level, option II This setting should be used when road surface conditions are very rough for increased ground clearance. Speed dependent lowering of vehicle chassis (approximate values): • at standstill - raised by approx. one inch (24 mm) • between 0 mph (0 km/h) and 35 mph (6o km/h) - lowered progressively by approx. 3/8 inch (10 mm)

• between 35 mph (60 km/h) and 100 mph

(160 km/h) – lowered progressively by additional approx. one half inch (14 mm)

Parking assist (Parktronic) The Parktronic system assists the driver during parking maneuvers. It visually and audibly indicates the relative distance between the vehicle and an obstacle. The front area of the vehicle is monitored when driving forward. When reversing or with the gear selector lever in position “N”, the front as well as the rear areas are monitored. With the electronic key in starter switch position 2, Parktronic engages automatically at speeds up to approximately 10 mph (15 km/h) and deactivates during higher speeds. Parktronic can be switched off by a control switch located in the center console. It engages automatically again when starting the engine. See page 283 for parktronic switch.

Warning! Parktronic is a supplemental system. It is not intended to nor does it replace the need for extreme care. The responsibility during parking and other critical maneuvers rests always with the driver. Special attention must be paid to objects having smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or street curbs). Such objects may not be detected by the system and can damage the vehicle. The operational function of the Parktronic can be affected by dirty sensors, especially at times of snow and ice. See page 378 for notes on cleaning the parktronic system sensors. Interference caused by other ultrasonic signals (e.g. working jackhammers or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration.

Malfunction and indicator lamps in the instrument cluster

General information: If a bulb in the instrument cluster fails to light up during the bulb self-check when turning the electronic key in starter switch to position 2, have it checked and replaced if necessary.

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 comes on continuously 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.

Notes: When running out of fuel, the “CHECK ENGINE” malfunction indicator lamp comes on and the engine possibly switches to its limp-home (emergency operation) mode. To cancel the limp-home mode, the engine may have to be started three or four times after refueling. The malfunction indicator lamp remains illuminated. Have the system checked at your authorized Mercedes-Benz Center immediately.

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 92 for notes on airbags, see page 91 for belt tensioners and page 102 for infant and child seat restraint.

1 Fuel reserve indicator When the warning lamp (1) comes on after starting the engine, or if it comes on while driving, it indicates that the fuel level is down to the reserve quantity of approximately 2.9 gal (11 liters). See page 284 for notes on refueling the vehicle.

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. Parktronic, 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 269 for notes on antilock brake system (ABS).

Electronic stability program (ESP) — warning lamp

Distronic (DTR) – 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 271 if the warning lamp lights up or flashes when the vehicle is moving.

With the electronic key in starter switch position 2, the distance warning lamp in the speedometer dial comes on and goes out

with the engine running. See Distronic (DTR) system on page 321 for possible malfunction messages.

Note: The distance warning lamp is without a warning function on vehicles without distronic (DTR).

short time if the driver’s 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.

Malfunction and indicator lamp in the center console

AIRBAG OFF indicator lamp The 7 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 7 indicator lamp stays lit as long as a BabySmartTM child seat is properly installed on the front passenger seat. It indicates that the front passenger airbag is switched off. See page 88 for BabySmartTM airbag and its deactivation system.

Baby SmartTM is a trademark of Siemens Automotive Corp.

Malfunction and warning messages in the multifunction display Malfunction and warning messages for the following systems will be displayed immediately in the multifunction display. They are divided into three categories. Category C1: Messages of most immediate priority. These cannot be cleared from the instrument cluster using the J button. Categories C2 and C3: Messages of less immediate priority. These can be cleared from the instrument cluster using the J button and are then stored in the malfunction message memory, see page 136

Note: Certain malfunction and warning messages are accompanied by an audible signal. Malfunction and warning messages in red are always accompanied by an audible signal. Temporary messages such as “TRUNK OPEN!” will not be stored in the malfunction message memory.

Warning! All categories of messages contain important information which should be taken note of and, where malfunction indicated, addressed as soon as possible at an authorized Mercedes-Benz Center. Failure to repair condition noted may cause damage not covered by the Mercedes-Benz Limited Warranty, or result in property damage or personal injury.

CHECK LEVEL!

C*

* C = Category, see page 297

The low engine coolant level warning should not be ignored. Extended driving with the symbol displayed may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty. In cases of major or frequent minor coolant loss, have the cooling system checked at your authorized Mercedes-Benz Center as soon as possible.

Note: Do not drive without coolant in the cooling system. The engine will overheat causing major engine damage. Monitor the coolant temperature gauge while driving, see page 117. See page 333 for instructions on topping up the coolant.

When this message appears while driving, the coolant level has dropped below the required level. If no leaks are noticeable and the engine temperature does not increase, continue to drive to the nearest service station and have coolant added to the coolant system.

Warning! Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You can be seriously burned.

1 This may indicate that the poly-V-belt has broken. Should this

condition occur, the poly-V-belt must be replaced before continuing to operate the vehicle. Otherwise, the engine will overheat due to an inoperative water pump which may result in damage to the engine. Do not continue to drive the vehicle with this message displayed. Doing so could result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty.

2 The cooling fan for the coolant is faulty. Observe the coolant

temperature gauge. See page 117

During severe operating conditions and stop-and-go city traffic, the coolant temperature may rise close to the red marking. The engine should not be operated with the coolant temperature in the red zone. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.

Warning! Driving when your engine is badly overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Turn off the engine, get out of the vehicle and do not stand near the vehicle until it cools down.
