2010 Mercedes-benz GLK Class Owners Manual

Cleaning the windows and the wiper blades ! The windshield wipers must be in a

vertical position before folding them away from the windshield. They could otherwise damage the hood. Never open the hood when the wiper arms are folded forward.

X Make sure the hood is fully closed. X Switch on the ignition. X With wiper arms in vertical position, switch

off the ignition. G Warning! For safety reasons, switch off wipers and remove SmartKey from starter switch 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.

Vehicle care 255

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. 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 windows with hard objects such as an ice scraper or ring. Doing so may damage the windows.

Cleaning the panorama roof 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 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.

256 Vehicle care

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. This applies especially 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. 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.

Version: 2.11.8.1

! 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.

Audio or COMAND display ! You must switch off the audio or

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 or COMAND display screen.

X Use a standard microfiber cloth and apply

with light pressure.

Steering wheel and gear selector lever 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.

Vehicle care 257

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.

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.

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.

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. 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 the activation of the NECK-PRO active front head restraints and/ or the deployment of the front side impact air bags. Contact an authorized Mercedes-Benz Center for availability. Leather upholstery Please note that leather upholstery is a natural product and is therefore subject to a natural aging process. 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.

! 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.

Possible causes/consequences and M Solutions The tire inflation pressure in at least one tire is significantly below the reference value. The respective tire is indicated in the multifunction display. X Carefully bring the vehicle to a halt, avoiding abrupt

steering and braking maneuvers.

X Check and adjust tire inflation pressure as required. X If necessary, change the wheel (Y page 312).

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.

G Warning! Driving with the message Check Brake Fluid Level displayed can result in an accident. Have your brake system checked immediately. Do not add brake fluid before checking the brake system. Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned.

! If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum mark

or below, have the brake system checked for brake pad thickness and leaks.
