Engine oil level indicator

P54.30-3607-26

To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan. The message “PERF. SERV. ON TIME” (perform service [engine oil level check] on time) will be displayed if the required waiting period has not been observed after stopping the engine: • with engine at operational temperature

approximately 5 minutes.

• with engine not at operational temperature up to

approximately 30 minutes.

The engine oil level check can be repeated after a short time. Turn the electronic key in starter switch to position 2. To call up the trip odometer and main odometer, press button è or ÿ on the multifunction steering wheel until the display appears. See page 96. Press button j or k on the multifunction steering wheel repeatedly until the “MEASUREMENT CORRECT – ONLY IF VEH. LEVEL” engine oil level indicator appears. This indicator is only a reminder. Measurement can be cancelled by pressing button j or k if the vehicle is not parked on level ground. An incorrect reading will be recorded if you do not cancel the measurement. Move the vehicle to level ground and measure again. The electronic key in starter switch is not in position 2 if the “ENGINE OIL LEVEL – SWITCH ON IGNITION” message appears. The “ENGINE OIL LEVEL – MEASURING NOW” message is displayed after approximately 3 seconds.

One of the following messages will subsequently appear on the indicator: “ENGINE OIL LEVEL – O.K.” No oil needs to be added. “ENGINE OIL LEVEL – ADD 1.0 QUART” (Canada: 1.0 L) “ENGINE OIL LEVEL – ADD 1.5 QUART” (Canada: 1.5 L) “ENGINE OIL LEVEL – ADD 2.0 QUART” (Canada: 2.0 L) See “Checking engine oil level”, on page 300 for instructions on adding engine oil. “ENGINE OIL LEVEL – REDUCE OIL LEVEL” Do not overfill the engine. Excessive oil must be siphoned or drained off. It could cause damage to the engine and catalytic converter not covered by the Mercedes-Benz Limited Warranty.

The “PERF. SERV. ON TIME” message will be displayed if a proper oil level check cannot be performed. The engine oil level check can be repeated after a short while. Perform the engine oil level check with the dipstick, if it cannot be completed via the multifunction display. See “Checking engine oil level”, on page 300. In this case we recommend that you have the system checked at a Mercedes-Benz Center.

Notes: See malfunction and warning messages on page 274 and page 283 if an engine oil level indicator appears on the multifunction display when the engine is running. The engine oil level cannot be checked while the engine is running. The “ENGINE OIL LEVEL – NOT WHEN ENGINE ON” message will appear.

Engine oil consumption Engine oil consumption checks should only be made after the break-in period. During the break-in period, higher oil consumption may be noticed and is normal. Frequent driving at high engine speeds results in increased consumption.

Climate control The system is always at operational readiness, except when manually switched off. The climate control only operates with the engine running. The temperature selector should be left at the desired temperature setting. The temperature selected is reached as quickly as possible. The system will not heat or cool any quicker by setting a higher or lower temperature. The desired interior temperature can be selected separately for the left and right side of the passenger compartment. The climate control removes considerable moisture from the air during operation in the cooling mode. It is normal for water to drip on the ground through ducts in the underbody. The air conditioning will not engage (no cooling) if the economy mode S is selected, see page 145.

Notes: Do not obstruct the air flow by placing objects on the air flow-through exhaust slots below the rear window. Also keep the air intake grill in front of the windshield free of snow and debris. The storage compartment between the front seats can be ventilated. See page 158 for notes on ventilating the storage space under the armrest in the center console. The air conditioner switches itself off for its own protection if refrigerant is lost. No cooling will then take place. Economy mode S cannot be switched off. Have the air conditioner checked by a Mercedes-Benz Center should this happen.

Dust filter Nearly all dust particles and pollen are filtered out before outside air enters the passenger compartment through the air distribution system.
