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

! Use only engine oils and oil filters that

have been approved for vehicles equipped with a service system. A list of the engine oils and oil filters tested and approved in accordance with the Mercedes-Benz Specifications for Service Products can be obtained from any authorized Mercedes- Benz Center. Damage to the engine or exhaust system is caused by the following: Rusing engine oils and oil filters which

have not been specifically approved for the service system.

Rreplacing the engine oil or oil filter after the replacement interval required by the service system has elapsed Rusing engine oil additives.

Example: engine oil cap

Engine oil cap (G 55 AMG) X Turn cap : counterclockwise and remove

it.

X Add the amount of oil required. Observe the specifications in the on-board computer when doing so or fill carefully to the maximum mark on the oil dipstick. i The difference in quantity between the

MIN mark and the MAX mark on the dipstick is approximately 2.1 US qts. (2 l). ! Do not add too much oil. If the oil level is above the "max" mark on the dipstick, too much oil has been added. This can lead to damage to the engine or the catalytic converter. Have excess oil siphoned off. For further information on engine oil, see (Y page 275). X Replace cap : on the filler neck and

tighten clockwise. Ensure that the cap locks into place securely.

Checking and adding other service products Coolant level Only check the coolant level when the vehicle is on a level surface and the engine has cooled down.

214 Engine compartment

X Turn the SmartKey to position

2(Y page 115) in the ignition lock.

X Check the coolant temperature display in

the instrument cluster. The coolant temperature must be below 158 ‡ (70 †). G WARNING In order to avoid any potentially serious burns: Ruse 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 display indicates that the coolant is overheated.

Rdo not remove the pressure cap on the

coolant reservoir if the coolant temperature is above 158 ‡ (70 †). Allow the engine to cool down before removing the cap. The coolant reservoir contains hot fluid and is under pressure.

Rusing a rag, slowly turn the cap

approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure.

Rdo not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts.

X Slowly turn cap : half a turn

counterclockwise and allow excess pressure to escape.

X Turn cap : further counterclockwise and

remove it. If the coolant is at the level of marker bar = in the filler neck when cold, there is enough coolant in coolant expansion tank ;. If the coolant is approximately 0.6 in (1.5 cm) above marker bar = in the filler neck when warm, there is enough coolant in coolant expansion tank ;.

X If necessary, add coolant that has been tested and approved by Mercedes-Benz.

X Replace cap : and turn it clockwise as far

as it will go.

For further information on coolant, see (Y page 276).

Windshield washer system and headlamp cleaning system The washer fluid reservoir is used for both the windshield washer system and the headlamp cleaning system. G WARNING Washer solvent/antifreeze is highly flammable. Do not spill washer solvent/ antifreeze on hot engine parts, because it may ignite and burn. You could be seriously burned.

! At temperatures below freezing: always fill the washer fluid reservoir with a mix of water and windshield washer concentrate (e.g. MB WinterFit). There is otherwise a risk of damaging the windshield washer system/headlamp cleaning system.

! Only use washer fluid concentrate which

is suitable for plastic lenses. Unsuitable washer fluid concentrate could damage the plastic lenses of the headlamps.

Care Notes on care Regular care of your vehicle is a condition for retaining the quality in the long term. Use care products and cleaning agents recommended and approved by Mercedes- Benz. G WARNING Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your

vehicle's doors or windows when cleaning the inside. Never use fluids or solvents that are not designed for cleaning your vehicle. Always lock away cleaning products and keep them out of reach of children.

! For cleaning your vehicle, do not use any

of the following: Rdry, rough or hard cloths Rabrasive cleaning agents Rsolvents Rcleaning agents containing solvents Do not scrub. Do not touch the surfaces or protective films with hard objects, e.g. a ring or ice scraper. You could otherwise scratch or damage the surfaces and protective film. H Environmental note Dispose of empty packaging and cleaning cloths in an environmentally responsible manner.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Exterior care Automatic car wash G WARNING Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, you must drive particularly carefully after washing the vehicle until the brakes have dried.

Care 217

You can wash the vehicle in an automatic car wash from the very start. ! Never clean your vehicle in a Touchless Automatic Car Wash as these use special cleaning agents. These cleaning agents can damage the paintwork or plastic parts.

If the vehicle is very dirty, pre-wash it before cleaning it in an automatic car wash. ! Make sure that the automatic car wash is suitable for the size of the vehicle. Fold in the exterior mirrors before the vehicle is washed. The exterior mirrors could otherwise be damaged.

! Make sure that the automatic

transmission is in position N when washing your vehicle in a tow-through car wash. The vehicle could be damaged if the transmission is in another position.

! Make sure that:

Rthe side windows and sliding sunroof are

closed completely.

Rthe blower for the ventilation/heating is switched off (airflow control is turned to position 0/the à and Á buttons are switched off).

Rthe windshield wiper switch is at position

0.

The vehicle could otherwise be damaged. After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the windshield.

Washing by hand When using the vehicle in winter, remove all traces of road salt deposits carefully and as soon as possible. When washing the vehicle underbody, also clean the inside of the wheels. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Thoroughly hose down the vehicle with a

gentle jet of water.

X Do not point the water jet directly towards

the air inlets.

X Use plenty of water and rinse out the

sponge frequently.

X Rinse the vehicle with clean water and dry

thoroughly with a chamois.

X Do not let the cleaning agent dry on the

paintwork.

Power washers G WARNING Do not use power washers with circular jet nozzles (concentrated-power jets) to clean your vehicle, especially for cleaning tires. You could otherwise damage the tires and cause an accident.

! Always maintain a distance of at least

11.8 in (30 cm) between the vehicle and the power washer nozzle. Information about the correct distance is available from the equipment manufacturer. Move the power washer nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtires Rdoor gaps, roof gaps, joints, etc. Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim Rventilation slots Damaged seals or electrical components can lead to leaks or failures.

Cleaning the wheels ! Do not use acidic wheel cleaning products to remove brake dust. This could damage wheel bolts and brake components.

! Do not park the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after cleaning. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked.

Cleaning the paintwork Scratches, corrosive deposits, areas affected by corrosion and damage caused by inadequate care cannot always be completely repaired. In such cases, visit a qualified specialist workshop. X Remove dirt immediately, where possible,

while avoiding rubbing too hard.

X Soak insect remains with insect remover and rinse off the treated areas afterwards. X Soak bird droppings with water and rinse

off the treated areas afterwards.

X Remove coolant, brake fluid, tree resin, oils, fuels and greases by rubbing gently with a cloth soaked in petroleum ether or lighter fluid.

X Use tar remover to remove tar stains. X Use silicone remover to remove wax. ! Do not affix:

Rstickers Rfilms Rmagnetic plates or similar items to painted surfaces. You could otherwise damage the paintwork.

If water no longer forms "beads" on the paint surface, use the paint care products recommended and approved by Mercedes- Benz. This is the case approximately every

three to five months, depending on the climate conditions and the care product used. If dirt has penetrated the paint surface or if the paint has become dull, the paint cleaner recommended and approved by Mercedes- Benz should be used. Do not use these care products in the sun or on the hood while the hood is hot. X Use a suitable touch-up stick, e.g. MB

Touch-Up Stick, to correct smaller areas of paint damage quickly and provisionally.

Matte finish care If your vehicle has a clear matte finish, observe the following instructions in order to avoid damage to the paintwork due to incorrect care. These notes also apply to light alloy wheels with a clear matte finish. ! Never polish the vehicle or the light alloy

wheels. Polishing causes the finish to shine.

! Never use paint cleaner, buffing or

polishing products, or gloss preserver, e.g. wax. These products are only suitable for high-gloss surfaces. Their use on vehicles with matte finish leads to considerable surface damage (shiny, spotted areas). Always have paintwork repairs carried out at a qualified specialist workshop.

! Do not use wash programs with a hot wax

treatment under any circumstances.

i Use only insect remover and car shampoo

from the range of recommended and approved Mercedes-Benz care products.

H Environmental note

Batteries contain dangerous substances. It is against the law to dispose of them with the household rubbish. They must be collected separately and recycled to protect the environment. Dispose of batteries in an environmentally friendly manner. Return discharged batteries to a qualified specialist workshop or to a special collection point for used batteries.

Fire, naked flames and smoking are prohibited when handling the battery. Avoid creating sparks. Battery acid is caustic. Avoid contact with the skin, eyes or clothing. Wear suitable protective clothing, in particular gloves, an apron and a face mask. Immediately rinse acid splashes off with clean water. Consult a doctor if necessary.

G WARNING Failure to follow these instructions can result in severe injury or death. Never lean over batteries while connecting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc.

G WARNING Do not place any metal objects on the battery as this could result in a short circuit. Use leak-proof batteries only to avoid the risk of acid burns in the event of an accident. Take care that you do not become statically charged, e.g. by wearing synthetic clothing or rubbing against textiles. For this reason, you also should not pull or push the battery over carpets or other synthetic materials. Never touch the battery first. First, touch the outside body of the vehicle in order to release any possible electrostatic charges. Do not rub the battery with rags or cloths. The battery could explode if touched due to electrostatic charge or due to spark formation.

! Switch off the engine and remove the

SmartKey before you loosen or disconnect the terminal clamps. You may otherwise destroy electronic components such as the alternator.

! Like other batteries, the vehicle battery may discharge over time if you do not use the vehicle. In this case, have the battery disconnected at a qualified specialist workshop. You can also charge the battery with a charger recommended by Mercedes- Benz. Contact a qualified specialist workshop for further information. The battery and the cover of the positive terminal clamp must be installed securely during operation.

i Remove the SmartKey if you park the vehicle and do not require any electrical consumers. The vehicle will then use very little energy, thus conserving battery power.

Jump-starting

G WARNING Failure to follow these directions will cause damage to the electronic components, and can lead to a battery explosion and severe injury or death. Never lean over batteries while connecting or jump starting. You might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water, and seek medical help if necessary. A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking, etc. Attempting to jump start a frozen battery can result in it exploding, causing personal injury. Read all instructions before proceeding.

! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may

damage the catalytic converter and create a risk of fire. Do not use a rapid charging device to start the vehicle. Make sure the jumper cables are not damaged. Make sure the jumper cables are not touching any other metal objects when they are connected to the battery.

If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jumper cables. Observe the following points: X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,

jump-start the vehicle using a second battery or a jump-starting device.

X You may only jump-start the vehicle when the engine and catalytic converter are cold. X Do not start the engine if the battery is frozen. Let the battery thaw first. X Jump-starting may only be performed from batteries with a nominal voltage of 12 V. X Only use jumper cables which have a sufficient cross-section and insulated terminal clamps. X Make sure that the jumper cables cannot come into contact with parts, such as the pulley

or the fan. These parts move when the engine is started and while it is running.

X If the battery is fully discharged, leave the battery that is being used to jump-start connected

for a few minutes before attempting to start. This charges the empty battery a little.

i Jumper cables and further information about jump-starting can be obtained from any

authorized Mercedes-Benz Center, for example. X Make sure that the two vehicles do not touch. X Apply the parking brake. X Move the selector lever to P. X Switch off all electrical consumers (e.g. radio, blower, etc.). X Open the hood (Y page 210).
