2009 Mercedes-benz R Class Owners Manual

Operation

Vehicle care products at an authorized Mercedes-Benz Center. Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the vehicle-care products recommended here. In such cases it is best to seek aid at an authorized Mercedes-Benz Center. The following topics deal with the cleaning and care of your vehicle and give important “how-to” information as well as references to Mercedes-Benz approved vehicle-care products.

Power washer ! Follow the instructions provided by the

power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. Never use a round nozzle to power-wash tires. The intense jet of water can result in damage to the tire. Always replace a damaged tire. Always keep the jet of water moving across the surface. Do not aim directly at electrical parts, electrical connectors, seals, or other rubber parts.

292

i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended.

Paintwork, painted body components ! Affixing stickers, magnets, adhesive tape

or similar materials to painted body components may damage the paintwork. Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not “bead up”. This should normally be done every 3 to 5 months, depending on the climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if the paint surface shows signs of embedded dirt (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot.

X Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.).

Engine cleaning Prior to cleaning the engine compartment, make sure to protect electrical components and connectors from contact with water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.

Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels. i Vehicles with KEYLESS-GO:

If a door handle is hit by a strong jet of water, and a SmartKey is within

approximately 3 ft (1 m) of the vehicle, it could be inadvertently locked or unlocked.

Hand-wash X Do not use hot water or wash your vehicle

in direct sunlight.

X Only use a soft, wet cloth or sponge to

clean the vehicle.

X Only use a mild vehicle wash detergent,

such as Mercedes-Benz approved Car Shampoo.

X Thoroughly spray the vehicle with a

diffused jet of water.

X Do not spray directly towards the

ventilation intake.

X Use plenty of water and rinse the sponge

and chamois frequently.

X Rinse with clean water and thoroughly dry

with a chamois. Do not allow cleaning agents to dry on the finish.

Automatic car wash You can have your vehicle washed in an automatic car wash from the start. Brushless car washes are preferable.

X To protect the filter system, activate the air recirculation mode using button : on the climate control panel.

! Do not clean your vehicle in an automatic

touchless car wash which uses caustic spray. Caustic spray will damage the paint or ornamental moldings.

If the vehicle is very dirty, prewash it before running it through the automatic car wash. ! Make sure the combination switch is set to wiper setting M. Otherwise, the rain sensor could activate and cause the wipers to move unintentionally. This may lead to vehicle damage. Due to the width of the vehicle, fold in exterior rear view mirrors prior to running the vehicle through an automatic car wash to prevent damage to the mirrors.

X When taking the vehicle through an automatic conveyor-type car wash: Make sure the automatic transmission remains in neutral position N. Observe instructions, see “Remaining in neutral position N” (Y page 137).

When leaving the automatic car wash, make sure the mirrors are folded out.

Operation

Vehicle care

After running the vehicle through an automatic car wash, wipe any wax off of the windshield and the wiper blade inserts. This will prevent smears and reduce wiping noise which can be caused by residual wax on the windshield.

Ornamental moldings X For regular cleaning and care of ornamental

moldings, use a damp cloth.

! Do not use chrome cleaner on ornamental moldings. Although ornamental moldings may have chrome appearance, they could be made of anodized aluminum that will be damaged when cleaned with chrome cleaner. Instead, use a damp cloth to clean those ornamental moldings. For very dirty ornamental moldings of which you are sure are chrome-plated, use a chrome cleaner. If in doubt whether an ornamental molding is chrome-plated, contact an authorized Mercedes-Benz Center.

293

Operation

Vehicle care Headlamps, brake lamps, tail lamps, side markers, turn signal lenses X Use a mild vehicle wash detergent, such as

Mercedes-Benz approved Car Shampoo, with plenty of water.

! Only use window cleaning solutions that

are suitable for plastic lamp lenses. Window cleaning solutions which are not suitable may damage the plastic lamp lenses of the headlamps. Therefore, do not use abrasives, solvents or cleaners that contain solvents.

Cleaning the Parktronic system sensors Parktronic system sensors are located in the front and rear bumper.

294

1 Parktronic system sensors in front

bumper

X Only clean sensors 1 by hand. X Use a mild vehicle wash detergent, such as

Mercedes-Benz approved Car Shampoo, with plenty of water and a soft, non- scratching cloth to clean sensors 1 on the bumpers.

! Applying strong pressure may damage

the sensor covers.

Cleaning the rear view camera lens

1 Camera lens X Only use clean water and a soft, non-

scratching cloth to clean camera lens 1. Be careful not to apply wax to camera lens 1 when waxing the vehicle. If necessary, remove the wax using the Mercedes-Benz approved Car Shampoo with plenty of water. ! Do not clean the camera and the area

around the camera Rwith a high-pressure cleaner Rwith a dry cloth and strong pressure Rwith aggressive cleaning agents You could otherwise damage the camera.

Cleaning the windows and the wiper blades ! Never open the hood when the wiper arms

are folded forward. G Warning! For safety reasons, switch off wipers and remove SmartKey from starter switch (vehicles with KEYLESS-GO: Make sure the vehicle’s on-board electronics have status 0) before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury.

! Do not pull on the wiper blade inserts.

They could tear.

X Fold the wiper arms forward until they snap

into place.

X Clean the windshield and the wiper blade

inserts with a clean cloth and mild detergent solution.

X Use a soft, clean cloth and a mild window cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recommended.

! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch or pressing the KEYLESS-GO start/stop button (vehicles with KEYLESS-GO). Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield.

! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Cleaning the panorama roof with power tilt/sliding panel The rear part of the tilt/sliding panel has a protective layer on the inside. X Use a soft, clean cloth and a mild window

cleaning solution. An automotive glass cleaner is recommended.

! Do not use a dry cloth, abrasives, solvents

or cleaners containing solvents. Do not

Operation

Vehicle care touch the protective layer with hard objects such as an ice scraper or ring. Never apply strong force and only use a soft, non- scratching cloth when cleaning the rear part of the tilt/sliding panel. Otherwise you may scratch or damage the protective layer.

Light alloy wheels If possible, clean wheels once a week. X Use Mercedes-Benz approved Wheel Care,

a soft bristle brush and a strong spray of water for cleaning the light alloy wheels.

! Only use acid-free cleaning materials.

Acid may cause corrosion or damage the clear coat.

! The vehicle should not be parked for an extended period of time immediately after it has been cleaned, especially not after the wheel rims have been cleaned with wheel rim cleaner. Wheel rim cleaners can lead to increased corrosion of the brake disks and brake pads. Non-approved wheel cleaners may also damage the wheel paint if the vehicle is not driven after cleaning.

295

Operation

Vehicle care

Therefore, the vehicle’s brake system should always be warmed-up before it is parked after cleaning. Drive your vehicle for several minutes to allow the brakes to dry. When applying Mercedes-Benz approved Tire Care and Mercedes-Benz approved Wheel Care products, take care not to spray them on the brake disks.

Plastic and rubber parts X Use a gentle dishwashing detergent or mild detergent for delicate fabrics as a washing solution.

X Wipe with a cloth moistened in a lukewarm

solution. The surface may temporarily change color. If this is the case, wait for it to dry. G Warning! Do not use cleaners or cockpit care sprays containing solvents to clean the cockpit or the steering wheel. Cleaners containing solvents will make the surface porous and vehicle occupants could suffer serious injuries from plastic parts coming loose in the event of air bag deployment.

! Do not use oil, wax or scouring agents.

Otherwise you may scratch or damage the surface.

Hard plastic trim items X Use Mercedes-Benz approved Interior Care on a soft, lint-free cloth and apply with light pressure.

COMAND display ! You must switch off the COMAND display

and allow it to cool prior to cleaning.

! Do not use any liquids or cleaning agents.

These can damage or even destroy the audio display screen.

X Use a standard microfiber cloth and apply

with light pressure.

Steering wheel X Wipe with a damp cloth and dry thoroughly

or clean with Mercedes-Benz approved Leather Care.

Carpets X Use Mercedes-Benz approved Carpet and

Fabric Care for cleaning the carpets.

Headliner X Use a soft bristle brush or a dry-shampoo

cleaner in case of excessive dirt.

Seat belts X Only use clear, lukewarm water and soap.

! The seat belts must not be treated with chemical cleaning agents. Do not dry the seat belts at temperatures above 176‡ (80†) or 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.

Upholstery Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g. when wet, etc.) may cause the upholstery to become permanently discolored. By lining the seats with a proper intermediate cover, contact-discoloration will be prevented.

296

G Warning! Only use seat or head restraint covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent Rdeployment of the front side impact air

bags

Rdeployment of the rear side impact air

bags

Leather upholstery may also react to certain ambient influences such as high humidity or high temperature by showing wrinkles for example. X Wipe leather upholstery with a damp cloth and dry thoroughly or clean with Mercedes- Benz approved Leather Care.

Operation

Vehicle care

! To avoid damage to leather upholstery:

RWipe with light pressure only. RDo not clean with abrasive cleaning

agents such as scouring milk or powder.

RDo not soak the leather upholstery.

As leather is a natural product, it could otherwise harden or become porous. RExercise particular care when cleaning

perforated leather as its underside should not become wet.

Chrome-plated exhaust tip Regular cleaning and care of chrome-plated exhaust tips will help to maintain their shine and the classy appearance. X Use Mercedes-Benz approved Chrome

Polishing Paste each time the vehicle has been washed, especially during the winter.

! Do not use alkaline cleaners such as

wheel cleaners as they could cause corrosion.

MB Tex upholstery X Use Mercedes-Benz approved Interior Care

onto a soft, lint-free cloth and apply with light pressure for cleaning the upholstery.

Wood trims X Only use water and a damp cloth to clean

wood trims in your vehicle.

! Do not use solvents like tar remover or wheel cleaner nor polishes or waxes as these may be abrasive.

Practical hints

G Warning! Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire. G Warning! Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.
