Engine compartment

Hood 
Important safety notes

WARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view. There is a risk of an accident.
Never unlatch the hood while driving.
When opening and closing the hood, it may suddenly fall into the closed position. There is a risk of injury to persons within range of movement of the hood.
Open and close the hood only when no one is within its range of movement.
heated or when there is a fire in the engine compartment could expose you to hot gases or other service products. There is a risk of injury.
Let an overheated engine cool down before opening the hood. If there is a fire in the engine compartment, keep the hood closed and contact the fire department.

WARNING
The engine compartment contains moving components. Certain components, such as the radiator fan, may continue to run or start again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine compartment:

• switch off the ignition
• never reach into the area where there is a risk of danger from moving components, such as the fan rotation area
• remove jewelry and watches
• keep items of clothing and hair, for example, away from moving parts

WARNING
The ignition system and the fuel injection sys-tem work under high voltage. If you touch components which are under voltage, you could get an electric shock. There is a risk of injury.
Never touch components of the ignition sys-tem or fuel injection system when the ignition is switched on.

Opening the hood

WARNING
Certain components in the engine compart-ment, such as the engine, radiator and parts of the exhaust system, can become very hot. Working in the engine compartment poses a risk of injury.
Where possible, let the engine cool down and touch only the components described in the following.
When the hood is open and the windshield wipers are set in motion, you can be injured by the wiper linkage. There is a risk of injury.
Always switch off the windshield wipers and the ignition before opening the hood.

Make sure that the windshield wipers are not folded away from the windshield. You could otherwise damage the windshield wipers or the hood.

• Make sure that the windshield wipers are turned off.
• Pull release lever 1 on the hood. The hood is released.
• Reach into the gap, pull hood catch han- dle 2 up and lift the hood.
  If you lift the hood by approximately 15 in (40 cm), the hood is opened and held open automatically by the gas-filled strut.

Closing the hood

• Lower the hood and let it fall from a height of approximately 8 in (20 cm).
  Check that the hood has engaged properly.  If the hood can be raised slightly, it is not properly engaged. Open it again and close it with a little more force.

Engine oil
General notes on the oil level
Depending on your driving style, the vehicle consumes up to 0.9 US qt (0.8 liters) of oil per 600 miles (1,000 km). The oil consumption may be higher than this when the vehicle is new or if you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be in a different location.
When checking the oil level:

• park the vehicle on a level surface.
• the engine should be switched off for approximately five minutes if the engine is at normal operating temperature.
  Rif the engine is not at normal operating temperature, e.g. if the engine was only started briefly, wait about 30 minutes before carrying out the measurement.

Checking the oil level using the oil dip-stick
WARNING Certain components in the engine compart-ment, such as the engine, radiator and parts of the exhaust system, can become very hot. Working in the engine compartment poses a risk of injury.
Where possible, let the engine cool down and touch only the components described in the following.

• Park the vehicle on a level surface. To check the oil level with the engine at operating temperature, switch the engine off and wait for approximately five minutes.
• Pull oil dipstick 1 out of the dipstick guide tube.
  Wipe off oil dipstick 1.
  Slowly slide oil dipstick 1 into the guide tube to the stop, and take it out again. If the level is between MIN mark 3 and MAX mark 2 the oil level is correct.
• If the oil level has dropped to MIN mark 3 or below, add 1.1 US qt (1.0 liter) engine oil.

Adding engine oil 

WARNING
Certain components in the engine compart-ment, such as the engine, radiator and parts of the exhaust system, can become very hot. Working in the engine compartment poses a risk of injury.
Where possible, let the engine cool down and touch only the components described in the following.
If engine oil comes into contact with hot components in the engine compartment, it may ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to the filler neck. Let the engine cool down and thoroughly clean the engine oil off the components before starting the engine.

Environmental note
When adding oil, take care not to spill any. If oil enters the soil or waterways, it is harmful to the environment.

Only use engine oils and oil filters that have been approved for vehicles with a service system. You can obtain a list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products at any Mercedes-Benz Service center.
Damage to the engine or exhaust system is caused by the following:

• using engine oils and oil filters that have not been specifically approved for the service system
• replacing engine oil and oil filters after the interval for replacement specified by the service system has been exceeded
• using engine oil additives.

Checking and adding other service products
Checking coolant level
WARNING Certain components in the engine compart-ment, such as the engine, radiator and parts of the exhaust system, can become very hot. Working in the engine compartment poses a risk of injury. Where possible, let the engine cool down and touch only the components described in the following.
The engine cooling system is pressurized, particularly when the engine is warm. When opening the cap, you could be scalded by hot coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the cap. Wear eye and hand protection when opening the cap. Open the cap slowly half a turn to allow pressure to escape.

Only check the coolant level when the vehicle is on a level surface and the engine has cooled down.
Turn the SmartKey to position 2 in the ignition lock (Y page 149).
On vehicles with KEYLESS-GO, press the Start/Stop button twice (Y page 149).
Check the coolant temperature display in the instrument cluster.
The coolant temperature must be below 158 ‡ (70 †).
