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 steering lock to position 2, have it checked and replaced if necessary.
On-board diagnostic system Check engine malfunction indicator lamp
CHECK ENGINE
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. See also page 228 for fuel cap placement warning. 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.
Brake warning lamp
BRAKE
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 and fuel cap placement warning
SRS
The operational readiness of the airbag system is verified by the indicator lamp “SRS” in the instrument cluster when
turning the electronic key in steering lock to position 1 or 2. If no malfunction 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 66 for notes on airbags, see page 65 for belt tensioners and page 74 for infant and child seat restraint.
N54.30-2756-21
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 2.1 gal (8 liters). The warning lamp blinks when the fuel cap is not closed, or a fuel system leak has been detected. Retighten cap and see if lamp goes out after restart and next OBD selfcheck. If the warning lamp continues to blink after closing the fuel cap correctly, have the fuel system checked at your authorized Mercedes-Benz Center as soon as possible. Leaving the engine running and the fuel cap open can also cause the “CHECK ENGINE” lamp to illuminate, see page 226.
Electronic stability program (ESP) — warning lamp
ABS malfunction indicator lamp
The yellow ESP warning lamp in the speedometer dial comes on with the electronic key in steering lock position 2.
It should go out with engine running. See page 217 if the warning lamp lights up or flashes when the vehicle is moving.
BAS/ESP malfunction indicator lamp
BAS ESP
The malfunction indicator lamp for the ESP is combined with that of the BAS. The yellow BAS/ESP malfunction indicator
lamp in the instrument cluster comes on with the electronic key in steering lock position 2. It should go out with the engine running. If the BAS/ESP malfunction indicator lamp remains illuminated with the engine running, see page 213 for notes on the brake assist (BAS) and page 217 for notes on the electronic stability program (ESP).
ABS
The ABS malfunction indicator lamp in the instrument cluster comes on with the electronic key in steering lock 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. With the ABS malfunctioning, the BAS and ESP are also switched off. Both malfunction indicator lamps 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 215 for notes on the antilock brake system (ABS).

Hood
Warning! To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running. Be sure the hood is properly closed before driving. When closing hood, use extreme caution not to catch hands or fingers. The radiator fan may continue to run for approximately 30 seconds or even restart after the engine has been turned off. Stay clear from fan blades.
The engine is equipped with a transistorized ignition system. Because of the high voltage it is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition system
• with the engine running, • while starting the engine, • if ignition is “on” and the engine is turned
manually.
If you see flames, steam or smoke coming from the engine compartment, or if the coolant temperature gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not open the hood until the engine has cooled. If necessary, call a fire department.

Checking engine oil level
1 Oil dipstick 2 Oil filler cap
To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check engine oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan.
Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three seconds to obtain accurate reading.
Oil level must be between the lower (min) and upper (max) mark of the dipstick.
Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 l). Do not overfill the engine. Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by the Mercedes-Benz Limited Warranty. See malfunction and warning messages on page 231 if an engine oil level display appears on the multifunction display when the engine is running.
Note: See page 112 for engine oil level indicator.

Coolant level
Engine compartment
Automatic transmission fluid level The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or gear shifting malfunctions, have your authorized Mercedes-Benz Center check the transmission fluid level.
P20.30-2032-26
To check the coolant level, the vehicle must be parked on level ground and the engine stopped. Check coolant level only when coolant is cold. The coolant level should reach the black top part of the reservoir.
Adding coolant If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain plugs for the cooling system are located on the right side of the engine block and at the bottom of the radiator. Anticorrosion/antifreeze mixture, see page 306.
Warning! In order to avoid possible serious burns or injury:
• Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
• Do not remove pressure cap on coolant
reservoir if engine temperature is above 194°F (90°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.
• Using a rag, slowly open cap approximately
1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure.
• Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts.

Spare wheel, vehicle jack
Vehicle jack
P40.10-2027-26
1 Jack arm 2 Jack base See illustration for proper storage of jack.
256
Before storing the jack on the felt in the spare wheel well, the jack arm must be lowered almost to the base of the jack.
Warning! The jack is designed exclusively for jacking up the vehicle at the jack tubes built into either side of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on hills. Always try to use the jack on level surface. Be sure that the jack arm is fully inserted in the jack tube. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.
Wheels Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your authorized Mercedes-Benz Center for further information. See your authorized Mercedes-Benz Center for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase.
Tire replacement Front tires should be replaced in sets. Rims and tires must be of the correct size and type. For dimensions, see “Technical Data” (page 300). We recommend that you break in new tires for approx. 60 miles (100 km) at moderate speed.
It is imperative that the wheel mounting bolts be fastened to a tightening torque of 80 ft.lb. (110 Nm) whenever wheels are mounted. For rim and tire specifications, refer to “Technical Data” (page 300).
Warning! Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace them. When replacing rims, use only genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident.

Rotating wheels The wheels can be rotated according to the degree of tire wear while retaining the same direction of travel. Rotating, however, should be carried out as recommended by the tire manufacturer, before the characteristic tire wear pattern (shoulder wear on front wheels and tread center wear on rear wheels) becomes visible, as otherwise the driving properties deteriorate.
Important! Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement.
Notes: Thoroughly clean the inner side of the wheels any time you rotate the wheels or wash the vehicle underside. The use of retread tires is not recommended. Retread tires may adversely affect the handling characteristics and safety of the vehicle. Dented or bent rims can cause tire pressure loss and damage to the tire beads. For this reason, check rims for damage at regular intervals. The rim flanges must be checked for wear before a tire is mounted. Remove burrs, if any. Check and ensure proper tire inflation pressure after rotating the wheels. For tire inflation pressure see inside of fuel filler flap and also page 265.
Spare wheel
Important! The spare wheel rim is mounted with a full size tire of the same type as on the vehicle, and is fully functional. However, that spare wheel rim is weight optimized and has a limited service life of 12 000 miles (20 000 km) use before a standard wheel rim must replace it. In the case of a flat tire, you may temporarily use the spare wheel. Do not operate vehicle with more than one spare wheel mounted. Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement.
If the arrow on tire side wall does not point in direction of vehicle forward movement when using the spare wheel, observe the following restriction: • Drive to the nearest tire repair facility as soon as
possible.
For rim and tire specifications, refer to “Technical Data” (page 300).
Warning! The spare wheel rim is for temporary use only. Use for over a total of 12 000 miles (20 000 km) (aggregate of all uses) may cause wheel rim failure leading to an accident and possible injuries.

Changing wheels
Warning! The jack is designed exclusively for jacking up the vehicle at the jack tubes built into either side of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on hills. Always try to use the jack on level surface. Be sure that the jack arm is fully inserted in the jack tube. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

Move vehicle to a level area which is a safe distance from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
3. Prevent vehicle from rolling away by blocking wheels with wheel chocks (not supplied with vehicle) or sizable wood block or stone. When changing a wheel on a hill, place chocks on the downhill side blocking both wheels of the other axle. On a level road, place one chock in front of and one behind the wheel that is diagonally opposite to the wheel being changed.
4. Using the wrench, loosen but do not yet remove the
wheel bolts.
5. Remove the protective cover from the jack support
tube opening by inserting the screwdriver (supplied in the tool kit) in the opening and prying it out. The tube openings are located directly behind the front wheel housings and in front of the rear wheel housings.

6. Insert jack arm fully into the tube hole up to the
stop. Place jack on firm ground. Position the jack so that it is always vertical (plumb-line) as seen from the side (see arrow), even if the vehicle is parked on an incline.
7. Jack up the vehicle until the wheel is clear of the ground. Never start engine while vehicle is raised.
8. Unscrew upper-most wheel bolt and install
alignment bolt (1) supplied in the tool kit. Remove the remaining bolts. Keep bolt threads protected from dirt and sand.
9. Remove wheel. Grip wheel from the sides. Keep
hands from beneath the wheels.
10. Clean contact surfaces of wheel and wheel hub.
Install spare wheel on wheel hub. Insert wheel bolts and tighten them slightly.
To avoid paint damage, place wheel flat against hub and hold it there while installing first wheel bolt. Unscrew the alignment bolt (1) to install the last wheel bolt.
11. Lower vehicle. Remove jack and insert jack tube
cover.
12. Using the wrench, tighten the five bolts evenly,
following the sequence illustrated, until all bolts are tight. Observe a tightening torque of 80 ft.lb. (110 Nm). Before storing the jack, the jack arm must be lowered almost to the base of the jack. For proper storage of vehicle jack see page 256.
13. Ensure proper tire pressure.

Warning! The spare wheel rim is for temporary use only. Use for over a total of 12 000 miles (20 000 km) (aggregate of all uses) may cause wheel rim failure leading to an accident and possible injuries.
Warning! Always replace wheel bolts that are damaged or rusted. Never apply oil or grease to wheel bolts. Damaged wheel hub threads should be repaired immediately. Incorrect mounting bolts or improperly tightened mounting bolts can cause the wheel to come off. This could cause an accident. Be sure to use the correct mounting bolts.
Tire inflation pressure A table (see fuel filler flap) lists the tire inflation pressures specified for Mercedes-Benz recommended tires as well as for the varying operating conditions.
Important! Tire pressure changes by approx. 1.5 psi (0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage – especially in the winter. Example: If garage temperature = approx. +68°F (+20°C) and ambient temperature = approx. +32°F (0°C) then the adjusted air pressure = specified air pressure +3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values offering high driving comfort. Increased inflation pressures for heavy loads produce favorable handling characteristics with lighter loads and are perfectly permissible. The ride of the vehicle, however, will become somewhat harder. Tire temperature and pressure increase with the vehicle speed. Tire pressure should therefore only be checked and corrected on cold tires. Correct tire pressure in warm tires only if pressure has dropped below the pressure listed in the table and the respective operating conditions are taken into consideration. An underinflated tire due to a slow leak (e.g. due to a nail in the tire) may cause damage such as tread separation, bulging etc.. Regular tire pressure checks (including the spare tire) at intervals of no more than 14 days are therefore essential.

If a tire constantly loses air, it should be inspected for damage. The spare tire should be checked periodically for condition and inflation. Spare tire will age and become worn over time even if never used, and thus should be inspected and replaced when necessary.
Warning! Do not overinflate tires. Overinflating tires can result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.. Follow recommended inflation pressures. Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the driver’s door latch post). Overloading the tires can overheat them, possibly causing a blowout.
