Breaking-in notes

Mercedes-AMG vehicles: observe the notes in the Supplement. Otherwise, you may not recog‐ nize dangers.

To preserve the engine during the first 1,000 miles (1,500 km):

• Drive at varying road speeds and engine speeds.
• Do not drive at speeds greater than 85 mph (140 km/h).
• Drive the vehicle in drive program or .
• Change gear before the tachometer needle is Ô of the way to the red area of the tachome‐ ter.
• Do not shift down a gear manually in order to brake.
• Avoid overstraining the vehicle, e.g. driving at full throttle.
• Do not depress the accelerator pedal past the pressure point (kickdown).
• Only increase the engine speed gradually and accelerate the vehicle to full speed after 1,000 miles (1,500 km).

This also applies when the engine or parts of the drivetrain have been replaced.

Please also observe the following breaking-in notes:

• In certain driving and driving safety systems, the sensors adjust automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in process.
• Brakepads, brake discs and tires that are either new or have been replaced only achieve optimum braking effect and grip after several hundred kilometers of driving. Compensate for the reduced braking effect by applying greater force to the brake pedal.

Service work which is not carried out at the right time or incompletely can lead to increased wear and damage to the vehicle.

• Always observe the prescribed service intervals.
• Always have the prescribed service work carried out at a qualified specialist workshop.

Special service requirements

The prescribed service interval is based on nor‐ mal operation of the vehicle. Maintenance work will need to be performed more often if the vehi‐ cle is operated under arduous conditions or increased loads.

The ASSYST PLUS service interval display is only an aid. The driver of the vehicle bears responsi‐ bility as regards to whether maintenance work needs to be performed more often than speci‐ fied based on the actual operating conditions and/or loads.

Examples of arduous operating conditions:

• regular city driving with frequent intermedi‐ ate stops
• mainly short-distance driving frequent operation in mountainous terrain or on poor road surfaces
• when the engine is often left idling for long periods
• operation in particularly dusty conditions and/or if air-recirculation mode is frequently used

In these or similar operating conditions, have the interior air filter, engine air cleaner, engine oil and oil filter etc. changed more frequently. The tires must be checked more frequently if the vehicle is operated under increased loads. Fur‐ ther information can be obtained at a qualified specialist workshop.

Battery disconnection periods

The ASSYST PLUS service interval display can only calculate the service due date when the battery is connected.

• Note down the service due date displayed on the instrument display before disconnecting the battery (→ page 344).

WARNING Risk of burns from hot com‐ ponent parts in the engine compartment

Certain component parts in the engine com‐ partment can be very hot, e.g. the engine, the cooler and parts of the exhaust system.

• Let the engine cool down and only touch the component parts described as follows.

Requirements:

The engine must have an oil dipstick. If not, the engine oil level can be checked only with the onboard computer .

Depending on the engine, the oil dipstick may be installed in the engine compartment in different locations.

The waiting time before checking the oil level when the engine is at normal operating tempera‐ ture is five minutes.

• Park the vehicle on a level surface.
• Pull oil dipstick 1 out and wipe off.
• Slowly slide oil dipstick 1 into the guide tube to the stop, and pull it out again after approximately three seconds.
  • Oil level is correct: oil level is between 2 and 3.
  • Oil level too low: oil level is at 3 or below.
  • Oil level too high: oil level is above 2.
• If the oil level is too low, add 1.1 US qt liter) of engine oil.
• If the engine oil level is too high, have the excess engine oil removed immediately at a qualified specialist workshop.

Checking the engine oil level with an onboard computer

Requirements:

The engine oil level is determined during driving.

Determining the engine oil level can take up to 30 minutes with a normal driving style and even longer with an active driving style

In order to receive a result as quickly as possi‐ ble:

• warm up the engine.
• park the vehicle on a level surface.
• leave the engine running at idle speed.

On-board computer:

Service Engine Oil Level

• Turn cap 1 counter-clockwise and remove it.
• Add engine oil.
• Replace cap 1 and turn it clockwise as far as it will go.
• Check the oil level again (→ page 348).

Cleaning and care

Notes on washing the vehicle in a car wash

WARNING Risk of accident due to reduced braking effect after washing the vehicle

The braking effect is reduced after washing the vehicle.

• After the vehicle has been washed, brake carefully while paying attention to the traffic conditions until the braking effect has been fully restored.

NOTE Damage due to unsuitable car wash

• Before driving into a car wash make sure that the car wash is suitable for the vehicle dimensions.
• Ensure there is sufficient ground clear‐ ance between the underbody and the guide rails of the car wash.
• Ensure that the clearance width of the car wash, in particular the width of the guide rails, is sufficient.

To avoid damage to your vehicle when using a car wash, ensure the following beforehand:

• to avoid possible water ingress in the vehicle, it is preferable to use car washes which allow the high-pressure pre-cleaning to be deacti‐ vated (specification for the convertible pro‐ gram).
• it is imperative to avoid a subsequent hotwax treatment.
• remove the SmartKey in order to ensure that the wind deflector on the windshield retracts.
• Active Distance Assist DISTRONIC and the HOLD function are deactivated.
• the 360° Camera or the rear view camera is switched off.
• the side windows and soft top are closed completely.
• the blower for the ventilation/heating is switched off. he windshield wiper switch is in position g.
• the SmartKey is at a minimum distance of ft (3 m) away from the vehicle, otherwise the trunk lid could open unintentionally.
• in car washes with a conveyor system: neu‐ tral N is engaged.

In car washes with a conveyor system: if you would like to leave the vehicle while it is being washed, make sure the SmartKey is located in the vehicle. The P gear is other‐ wise automatically engaged.

If, after the car wash, you remove the wax from the windshield and wiper rubbers, this will prevent smearing and reduce wiper noise.

Information on using a power washer

WARNING Risk of accident when using high-pressure cleaning equipment with round-spray nozzles

The water jet from a round-spray nozzle (dirt grinder) may cause damage to tires and sus‐ pension components that is not visible.

Components damaged in this way may fail unexpectedly.

• Do not use high-pressure cleaning equipment with round-spray nozzles to clean your vehicle.
• Damaged tires or suspension compo‐ nents must be replaced immediately.

To avoid damage to your vehicle, observe the fol‐ lowing when using a power washer:

• keep the SmartKey at least 10 ft (3 m) away from the vehicle. Otherwise the trunk lid could open unintentionally.
• maintain a distance of at least 11.8 in (30 cm) to the vehicle.
• vehicles with decorative foil: parts of your vehicle are covered with a decorative foil. Maintain a distance of at least 27.6 in (70 cm) between the foil-covered parts of the vehicle and the nozzle of the power washer. Move the power washer nozzle around whilst cleaning. The water temperature of the power washer must not exceed 140 °F (60 °C).
• observe the information on the correct dis‐ tance in the equipment manufacturer's oper‐ ating instructions.
• do not point the nozzle of the power washer directly at sensitive parts such as tires, the soft top, the wind deflector net, slits, electri‐ cal component parts, batteries, light sources and ventilation slots.

Washing the vehicle by hand

Observe the legal requirements, e.g. in a number of countries, washing by hand is only permitted in specially designated wash bays.

• Use a mild cleaning agent, e.g. car shampoo.
• Wash the vehicle with lukewarm water using a soft car sponge. When doing so, do not expose the vehicle to direct sunlight.
• Carefully hose the vehicle off with water and dry using a chamois. Take care not to point the water jet directly towards the air inlet grille.
