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 rec- ommended and approved by Mercedes-Benz. ! 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 man- ner.
! Do not park up the vehicle for an extended period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
Care 483
increased corrosion of the brake discs and brake pads/linings. For this reason, you should drive for a few minutes after clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Care of the exterior Automatic car wash G WARNING Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, following a car wash, drive with particular care until the brakes are dry. G WARNING The vehicle is braked when the HOLD function or DISTRONIC PLUS is activated. Therefore, deactivate the HOLD function and DISTRONIC PLUS before the vehicle is washed in an auto- matic car wash.
You can wash the vehicle in an automatic car wash from the very start. Wash off excess dirt before cleaning the vehi- cle in an automatic car wash. ! In car washes with a towing mechanism, make sure that the automatic transmission is in transmission position N, otherwise the vehicle could be damaged. RVehicles with a key:
do not remove the key from the ignition lock. Do not open the driver's door or front-passenger door when the engine is switched off. Otherwise, the automatic transmission selects park position P automatically and locks the wheels. You can prevent this by shifting the auto- matic transmission to N beforehand.
RVehicles with KEYLESS-GO:
do not open the driver's door or front- passenger door when the engine is switched off. Otherwise, the automatic
484 Care
transmission selects park position P automatically and locks the wheels.
Observe the following to make sure that the automatic transmission stays in position N: X Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2(Y page 323) in
the ignition lock. Use the key instead of the Start/Stop but- ton on vehicles with KEYLESS-GO. X Depress and hold the brake pedal. X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal. X Release the electric parking brake. X Switch off the ignition and leave the key in
the ignition lock. ! Make sure that:
Rthe side windows and sliding sunroof are
closed completely.
Rthe blower for the ventilation/heating is switched off (OFF button is depressed). Rthe windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged. After using an automatic car wash, wipe off wax from the windscreen and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the wind- screen.
Washing by hand In some countries, washing by hand is only allowed at specially equipped washing bays. Observe the legal requirements for each indi- vidual country. X Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean. X Use a mild cleaning agent, such as a car shampoo approved by Mercedes-Benz.

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 up 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 clean- ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The vehicle can then be parked up.
Cleaning the paintwork Scratches, corrosive deposits, areas affected by corrosion and damage caused by inade- quate care cannot always be completely repaired. In such cases, visit a qualified spe- cialist workshop. X Remove impurities immediately, where
possible, whilst 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.

Raising the vehicle G WARNING If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised. There is a risk of injury. Only position the jack at the appropriate jack- ing point of the vehicle. The base of the jack must be positioned vertically, directly under the jacking point of the vehicle.
The following must be observed when raising the vehicle: Rto raise the vehicle, only use the vehicle-
specific jack that has been tested and approved by Mercedes-Benz. If used incor- rectly, the jack could tip over with the vehi- cle raised.
Rthe jack is designed only to raise and hold the vehicle for a short time while a wheel is being changed. It is not suited for per- forming maintenance work under the vehi- cle.
Ravoid changing the wheel on uphill and
downhill slopes.
Rbefore raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never disen- gage the parking brake while the vehicle is raised.
Rthe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large, load-bearing underlay must be used. On a slippery surface, a non-slip underlay must be used, e.g. rubber mats.
Rdo not use wooden blocks or similar
objects as a jack underlay. Otherwise, the jack will not be able to achieve its load- bearing capacity due to the restricted height.
Rmake sure that the distance between the underside of the tyres and the ground does not exceed 3 cm.
Rnever place your hands and feet under the
raised vehicle.
Rnever lie under the raised vehicle. Rnever start the engine when the vehicle is
raised.
Rnever open or close a door or the boot lid
when the vehicle is raised.
Rmake sure that no persons are present in
the vehicle when the vehicle is raised.

Always pay attention to the instructions and safety notices in "Changing a wheel" (Y page 524). Only use wheel bolts that have been designed for the wheel and the vehicle. For safety rea- sons, Mercedes-Benz recommends that you only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective wheel. Be sure to use the original-length wheel bolts when refitting the original wheel after it has been repaired.
Wheel bolts for: : 17" light-alloy wheel, 7-spoke design with MB Number A 22114017602, 18" light- alloy wheel and larger
; 17" light-alloy wheel, 5-spoke design, 17" light-alloy wheel, 7-spoke design with MB Number A 22114010202
= "Minispare" emergency spare wheel ! Always use wheel bolts ; or = to fit 17", 5-spoke/7-spoke wheels with MB Number A 221 401 02 02 or the "Minispare" emer- gency spare wheel. Using other wheel bolts when fitting 17", 5-spoke/7-spoke wheels or the "Minispare" emergency spare wheel could damage the brake system.
X Clean the wheel and wheel hub contact
surfaces.
X Slide the emergency spare wheel or the
spare wheel onto the centring pin and push it on.
X Tighten the wheel bolts until they are fin-
ger-tight.
X Unscrew the centring pin. X Tighten the last wheel bolt until it is finger-
tight.
Lowering the vehicle G WARNING Tyre pressure that is too high or too low can lead to a blow-out of the fitted emergency spare wheel/spare wheel, particularly when driving with a heavy load and increasing speed. There is a risk of accident. Check the tyre pressure of the emergency spare wheel or spare wheel and adjust it. When doing so, observe the specified tyre pressure.
X Turn the crank of the jack anti-clockwise
until the vehicle is once again standing firmly on the ground.
X Place the jack to one side.

your vehicle even if there is a total loss of pressure in one or more tyres. MOExtended tyres may only be used in con- junction with an activated tyre pressure loss warning system or with an activated tyre pres- sure monitor. The driving distance possible is 80 km when the vehicle is partially laden, and 30 km when the vehicle is fully laden. In addition to the vehicle load, the driving dis- tance possible depends upon: Rspeed Rroad condition Routside temperature The driving distance possible in run-flat mode may be reduced by extreme driving condi- tions/manoeuvres, or it can be increased through a moderate style of driving. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tyre pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 80 km/h. G WARNING When driving in emergency mode, the driving characteristics deteriorate, e.g. when corner- ing, accelerating quickly and when braking. There is a risk of accident. Do not exceed the stated maximum speed. Avoid abrupt steering and driving manoeu- vres, and driving over obstacles (kerbs, pot- holes, off-road). This applies in particular to a laden vehicle. Stop driving in emergency mode if: Ryou hear banging noises. Rthe vehicle starts to shake. Ryou see smoke and smell rubber. RESP® is intervening constantly. Rthere are tears in the sidewalls of the tyre. After driving in emergency mode, have the wheel rims checked at a qualified specialist
G WARNING The wheels could work loose if the wheel nuts and bolts are not tightened to the specified tightening torque. There is a risk of accident. Have the tightening torque immediately checked at a qualified specialist workshop after a wheel is changed.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated (: to A ). The tightening torque must be 150 Nm.
X Turn the jack back to its initial position and store it together with the rest of the tyre- change tool kit in the stowage well under the boot floor.
i When you are driving with the collapsible
emergency spare wheel fitted, the tyre pressure loss warning system or the tyre pressure monitor cannot function reliably. Only restart the tyre pressure loss warning system/tyre pressure monitor when the defective wheel has been replaced with a new wheel. Vehicles with tire pressure control system: all fitted wheels must be equipped with functioning sensors. The defective wheel should no longer be in the vehicle.
MOExtended tyres (tyres with run-flat characteristics) With MOExtended tyres (tyres with run-flat characteristics), you can continue to drive

workshop with regard to their further use. The faulty tyre must be replaced.
i When replacing one or all tyres, make
sure that you only use tyres marked MOExtended. Also ensure that they are of the specified size for the vehicle.
i Vehicles with MOExtended tyres are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you addi- tionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. winter tyres. A TIREFIT kit can be obtained from a qualified spe- cialist workshop.
Battery Important safety notes Work on the battery, e.g. removing or instal- ling, requires specialist knowledge and the use of special tools. Therefore, always have work on the battery carried out at a qualified specialist workshop. G WARNING Hybrid vehicles: ensure that you read the "HYBRID" supplement. You could otherwise fail to recognise dangers. G WARNING Work carried out incorrectly on the battery can, for example, lead to a short circuit and damage your vehicle's electronic system. This can disrupt driving safety systems such as ABS (anti-lock braking system) or ESP® (Elec- tronic Stability Program). RIf ABS malfunctions, the wheels can lock during braking. This limits the steerability of the vehicle when braking and the braking distance may increase. There is a risk of accident.
RIf ESP® malfunctions, the vehicle will not be stabilised if it starts to skid or a wheel starts to spin. There is a risk of accident.
You should therefore have all work involving the battery carried out at a qualified specialist workshop. G WARNING Comply with safety precautions and take pro- tective measures when handling batteries.
Risk of explosion
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. Wear eye protection.
Keep children away.
Observe this Owner's Man- ual.
G WARNING For safety reasons, Mercedes-Benz recom- mends that you only use batteries which have been tested and approved for your vehicle by Mercedes-Benz. These batteries provide increased impact protection to prevent vehi- cle occupants from suffering acid burns
should the battery be damaged in the event of an accident. To prevent acid burns, observe the following safety notes when handling batteries: Rdo not lean over the battery. Rdo not place any metal objects on a battery. Otherwise, you could cause a short circuit and the battery's gas mixture could ignite. Rmake sure that you do not create an elec- trostatic charge, e.g. by wearing synthetic clothing or as a result of friction on fabrics. Therefore, you should not pull or slide the battery over carpets or other synthetic materials.
Rnever touch the battery first. To discharge a possible electrostatic charge, step out of the vehicle first and touch the bodywork. Rdo not wipe the battery using a cloth. The battery may explode as a result of electro- static charge or due to flying sparks. H Environmental note
Batteries contain pollutants. It is illegal to dispose of them with the household rubbish. They must be collected sep- arately and disposed of in an environmentally responsible recycling system. Dispose of batteries in an environmentally responsible manner. Take discharged batteries to a qualified spe- cialist workshop or to a col- lection point for used batter- ies.
! Have the battery checked regularly at a
qualified specialist workshop. Observe the service intervals in the Service Booklet or contact a qualified specialist workshop for more information.
! You should have all work involving the
battery carried out at a qualified specialist workshop. In the exceptional case that it is
Battery
505
necessary for you to disconnect the battery yourself, make sure that: Ryou switch off the engine and remove the
key. On vehicles with KEYLESS-GO, ensure that the ignition is switched off. Check that all the indicator lamps in the instrument cluster are off. Otherwise, electronic components, such as the alternator, may be damaged.
Ryou first remove the negative terminal clamp and then the positive terminal clamp. Never swap the terminal clamps. Otherwise, the vehicle's electronic sys- tem may be damaged.
Rthe transmission is locked in position P after disconnecting the battery. The vehi- cle is secured against rolling away. You can then no longer move the vehicle. The battery and the cover of the positive terminal clamp must be fitted securely dur- ing operation.
In order for the battery to achieve the maxi- mum possible service life, it must always be sufficiently charged. Like other batteries, the vehicle battery may discharge over time if you do not use the vehicle. In such cases, have the battery dis- connected at a qualified specialist workshop. You can also charge the battery with a charger recommended by Mercedes-Benz. For more information, please contact a quali- fied specialist workshop. Have the battery charge checked more fre- quently if you use the vehicle mainly for short trips or if you leave it standing idle for a lengthy period. Consult a qualified specialist workshop if you wish to leave your vehicle parked up for a long period of time. i When you park the vehicle, remove the
key if you do not require any electrical con- sumers. The vehicle will then use very little energy, thus conserving battery power.
