Programming the remote control Programming G Warning! Only press the transmitter button on the integrated remote control if there are no persons or objects present within the sweep of the garage door. People could otherwise be injured by the movement of the door.

Remote control in the rear-view mirror

Garage door remote control A is not part of the garage door opener. i To achieve the best result, insert new batteries in garage door remote control A of your garage door drive before programming.

X Erase the memory of the integrated remote control (Y page 400) before programming it for the first time.

X Turn the key to position 2 in the ignition

lock.

X Press and hold one of transmitter

buttons ; to ? on the integrated remote control. After a short time, indicator lamp : will start flashing. It flashes about once per second.

i Indicator lamp : flashes immediately

the first time that the transmitter button is programmed. If this transmitter button has already been programmed, indicator lamp : will only start flashing at a rate of once per second after 20 seconds have elapsed.

X Keep the transmitter button depressed. X Point transmitter button B of garage door remote control A towards the transmitter buttons on the rear-view mirror at a distance of 2 to 12 inches (5 to 20 cm).

i The distance between garage door remote control A and the integrated garage door opener depends on the system of the garage door drive. You might require several attempts. You should test every position for at least 20 seconds before trying another position.

X Keep transmitter button B on garage door remote control A pressed until indicator lamp : starts to flash rapidly. The programming has been successful if indicator lamp : flashes rapidly.

transmitter button B on the garage door remote control.

If indicator lamp : goes out after approximately 20 seconds and has not flashed rapidly: X Release transmitter buttons ;, = or ?

on the integrated remote control and transmitter button B on the garage door remote control.

X Repeat the procedure for the other

transmitter buttons. When doing so, vary the distance between the garage door's remote control and the transmitter buttons in the rear-view mirror.

i If the garage door system works with a

rolling code, you must synchronize the remote control integrated into the rear- view mirror with the garage door system receiver after programming. You will find further information in the garage door opening system's operating instructions, e.g. the sections on "Synchronizing the transmitter" or "Registering a new transmitter". You can also call the hotline mentioned above.

Notes on programming the remote control Canadian radio frequency laws require a "break" (or interruption) of the transmission signals a few seconds after broadcasting. Therefore, these signals may not last long enough for the integrated remote control to recognize the signal during programming. Comparable with Canadian law, some U.S. garage door openers also have a built-in "interruption". If you live in Canada or have difficulties programming the garage door opener (regardless of where you live) when using the programming steps (see above), proceed as follows: X Press transmitter button (;, = or ?) and hold it down during the following steps until

the setup has been completed successfully.

X At the same time, press transmitter button B of the garage door remote control for two seconds, then release it for two seconds, then press it again for two seconds.

X Repeat this sequence on transmitter button B of the garage door remote control until the frequency signal has been saved.

X If the setup procedure is successful,

indicator lamp : flashes once slowly and goes out after a few seconds.

X Continue with the other programming

steps (see above).

Problems when programming If you have problems when programming the integrated remote control, please note the following: RCheck the transmitter frequency of garage door remote control A (which can usually be found on the rear of the remote control). The integrated remote control is compatible with devices that operate at frequencies between 280 and 390 MHz.

RReplace the batteries in garage door remote control A. This increases the likelihood of garage door remote control A sending a strong and precise signal to the integrated remote control on the rear-view mirror.

RWhen programming, hold garage door

remote control A at varying distances and angles from the transmitter button which you are programming. Try different angles at a distance of 2 to 12 inches (5 to 30 cm) or the same angle at different distances.

RIf there is another garage door remote

control for the same device, perform the programming steps again using the remote control. Before performing these steps,

400 Features

make sure that new batteries have been installed in the garage door remote control. RAlign the antenna cable of the garage door

opener unit. This can improve signal reception/transmission.

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 right 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 brake pads, thus drying them. The vehicle can then be parked up.

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.

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 automatic car wash.

You can wash the vehicle in an automatic car wash from the very start. ! It is preferable to use car washes with

adjustable26 high-pressure precleaning. In car washes that use high water pressures, there is a risk that a small amount of water may leak into the vehicle.

! 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. ! In car washes with a towing mechanism,

make sure that AUTOTRONIC is in transmission position N, otherwise the vehicle could be damaged. RVehicles with a SmartKey:

Do not remove the SmartKey from the ignition lock. Do not open the driver's door or front-passenger door when the engine is switched off. Otherwise, AUTOTRONIC selects park position P automatically and locks the wheels. You can prevent this by shifting AUTOTRONIC 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, AUTOTRONIC selects park position P automatically and locks the wheels.

Observe the following to make sure that the automatic transmission stays in position N:

Care 411

X Make sure the vehicle is stationary and the

ignition is switched off.

X Turn the key to position 2 (Y page 267) in

the ignition lock. Use the key instead of the Start/Stop button on vehicles with KEYLESS-GO.

X Depress and hold the brake pedal. X Shift the automatic transmission to

position N.

X Release the brake pedal. X Release the parking brake. X Switch off the ignition and leave the key in

the ignition lock.

! Make sure that the side windows are completely closed, that the ventilation/ heating is switched off and that the windshield wiper switch is set to 0. Otherwise, the rain/light sensor could be activated, triggering unintended wiper movements. This can cause damage to the vehicle.

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 Carefully remove all deposits of road salt as soon as possible when driving in winter. Also, clean the insides of the wheels when washing the underbody of the vehicle. X Do not use hot water and do not wash the

vehicle in direct sunlight.

X Use a soft car sponge for cleaning. X Use a gentle cleaning agent, e.g. a

Mercedes-Benz approved car shampoo.

X Wash down the vehicle with a gentle water

jet.

X Do not point the water jet directly at the air

inlets.

26 Corresponds to the specification for the Cabriolet program.

412 Care

X Use plenty of water and rinse the sponge

frequently.

X Rinse the vehicle with clean water and dry

it thoroughly with a chamois.

X Do not allow the cleaning agent to 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.

! Keep the distance between the vehicle

and the nozzle of the power washer at 11.8 in (30 cm). 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 joint Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim elements 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 right 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 brake pads, thus drying them. The vehicle can then be parked up.

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 immediately, e.g. an authorized Mercedes-Benz Center. 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.

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 painted surface, paint care products should be used that have been approved and recommended by Mercedes-Benz. This is the case approximately every three to five months, depending on climatic conditions and the care product used. If dirt has entered the paint surface or the paintwork has become dull, a paint cleaner should be used that has been approved and recommended by Mercedes-Benz.

Never use such care products in direct sunlight or on a hot hood. X Use a suitable touch-up stick, e.g. MB

Touch Up stick, for quick, temporary repair of damaged paintwork.

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. ! Never polish the vehicle. Polishing causes

the finish to shine.

! Do not use paintwork cleaner, grinding or polishing products or gloss preservers such as wax. These products are only suitable for high-gloss surfaces. Using them on vehicles with matte paintwork can cause severe damage to the surface (shiny, mottled patches). Always have paintwork repairs performed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

plastic trim. This maintains the high-quality look of the surfaces.

X Wipe the plastic trim with a damp, lint-free

cloth, e.g. a microfiber cloth.

X Heavy soiling: use car care and cleaning products recommended and approved by Mercedes-Benz. The surface may change color temporarily. Wait until the surface is dry again.

Cleaning the steering wheel and gear or selector lever X Wash thoroughly with a damp cloth or use

a leather care agent that has been recommended and approved by Mercedes- Benz.

Cleaning real wood and trim strips X Wipe the wooden trim and trim strips with

a damp, lint-free cloth, e.g. a microfiber cloth.

X Heavy soiling: use car care and cleaning products recommended and approved by Mercedes-Benz.

! Do not use solvent-based cleaning agents

such as tar remover, wheel cleaners, polishes or waxes. There is otherwise a risk of damaging the surface.

! Do not use chrome polish for trim strips. The trim strips have a chrome look but are mostly made of anodized aluminum and can lose their shine if chrome polish is used. Use a damp, lint-free cloth instead when cleaning the trim strips. Chrome polish can be used to remove very heavy soiling from trim strips which you are sure are made of chrome. If you are unsure as to whether a trim strip is chrome-plated or not, consult an authorized Mercedes- Benz Center.

Cleaning the seat covers ! Do not use microfiber cloths to clean

genuine leather, artificial leather or Alcantara® covers. If used often, these can damage the cover.

! Observe the following when cleaning: Rclean genuine leather covers carefully with a damp cloth and then wipe the covers down with a dry cloth. Make sure that the leather does not become soaked. It may otherwise become rough and cracked. Only use leather care agents that have been tested and approved by Mercedes-Benz. You can obtain these from a qualified specialist workshop, e.g. an authorized Mercedes- Benz Center.

Rclean artificial leather covers with a cloth moistened with a solution containing 1% detergent (e.g. dish washing liquid).

Rclean cloth covers with a microfiber cloth moistened with a solution containing 1% detergent (e.g. dish washing liquid). Rub carefully and always wipe entire seat sections to avoid leaving visible lines. Leave the seat to dry afterwards. Cleaning results depend on the type of dirt and how long it has been there.

Rclean Alcantara® covers with a damp cloth. Make sure you wipe entire seat sections to avoid leaving visible lines.

i Note that regular care is essential to

ensure that the appearance and comfort of the covers is retained over time.

Cleaning the seat belts X Use clean, luke-warm water and soap

solution.

! Do not clean the seat belts using chemical cleaning agents. Do not dry the seat belts by warming them above 176 ‡ (80 †) or placing them in direct sunlight.

G Warning Do not bleach or dye seat belts as this may severely weaken them. In a crash, they may not be able to provide adequate protection.

Cleaning the roof lining and carpets X Roof lining: use soft brushes or dry

shampoo if it is particularly dirty.

X Carpets: use carpet and textile cleaners

that have been approved and recommended by Mercedes-Benz.

Changing a wheel and mounting the spare wheel Preparing the vehicle G Warning The wheel and tire size of the emergency spare wheel/spare wheel may differ to that of the damaged wheel. When using an emergency spare wheel/spare wheel the handling characteristics of the vehicle may change. Adapt your style of driving accordingly. Never operate the vehicle with more than one emergency spare wheel/spare wheel that differs in size. Only use an emergency spare wheel/spare wheel of a differing size briefly and do not switch off ESP®. When using an emergency spare wheel, you must not exceed the maximum speed of 50 mph (80 km/h). G Warning Have the different-sized emergency spare wheel/spare wheel replaced with a new wheel as soon as possible at a qualified specialist workshop that has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

i Vehicles without an emergency spare

wheel/spare wheel are not equipped with a tire-change tool kit at the factory. For more information on which tools are required to perform a wheel change on your vehicle, e.g. wheel chock, alignment bolt, or lug wrench, consult an authorized Mercedes-Benz Center.

X Prepare the vehicle as described

(Y page 421).

X Remove the following items from the

stowage well under the trunk floor: Rthe emergency spare wheel Rthe vehicle tool kit Rthe folding wheel chock Rthe jack

X Secure the vehicle to prevent it from rolling

away.

Securing the vehicle to prevent it from rolling away G Warning Only jack up the vehicle on level ground or on slight inclines/declines. The vehicle could otherwise fall off the jack and injure you or others.

If your vehicle is equipped with a wheel chock, it can be found in the vehicle tool kit (Y page 420). The folding wheel chock is an additional securing measure to prevent the vehicle from rolling away, for example when changing a wheel.

X Fold both plates upwards :. X Fold out lower plate ;. X Guide the lugs on the lower plate fully into

openings in base plate =.

Securing the vehicle on level ground X On level ground: place chocks or other suitable items under the front and rear of the wheel that is diagonally opposite the wheel you wish to change.

Securing the vehicle on slight downhill gradients X On downhill gradients: place chocks or other suitable items in front of the wheels of the front and rear axle.

Raising the vehicle G Warning When jacking up the vehicle, only use the jack which has been specifically approved by Mercedes-Benz for your vehicle. The jack is designed exclusively for jacking up the vehicle at the jacking points built into both sides of the vehicle. The jack saddle must be placed centrally under the jacking point. The jack must always be vertical when in use, especially on inclines or declines. The jack is intended only for lifting the vehicle briefly for wheel changes. It is not suited for

performing maintenance work under the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. Always firmly engage the parking brake and block the wheels with wheel chocks or other sizable objects before raising the vehicle with the jack. Do not disengage the parking brake while the vehicle is raised. Make sure that the ground on which the vehicle is standing and where you place the jack is solid, level and not slippery. If necessary, use a large underlay. On slippery surfaces, such as tiled floors, you should use a non-slip underlay, for example a rubber mat. Do not use wooden blocks or similar objects as a jack underlay. Otherwise, the jack may not be able to achieve its load-bearing capacity if it is not at its full height. Never start the engine when the vehicle is raised. Also observe the notes on the jack.

X Turn the jack back to its initial position and store it together with the rest of the vehicle tool kit in the stowage well under the trunk floor.

i When you are driving with the emergency

spare wheel mounted, the tire pressure monitor cannot function reliably. Only restart the tire pressure monitor when the defective wheel has been replaced with a new wheel. All mounted wheels must be equipped with functioning sensors and the defective wheel should no longer be in the vehicle.

MOExtended run-flat system The MOExtended run-flat system allows you to drive on even if there is a complete loss of pressure in one or more tires. The MOExtended run-flat system may only be used in conjunction with the activated tire pressure loss warning system or with the activated tire pressure monitor. The maximum permissible distance which can be driven in run-flat mode depends on the cargo in the vehicle. You can drive 50 miles (80 km) if the vehicle is partially laden and 18 miles (30 km) if it is fully laden. The maximum permissible distance which can be driven in run-flat mode is counted from
