Vehicle Care

Before using cleaners, read and follow all safety instructions on the label. While cleaning the interior, open the doors and windows to get proper ventilation. To prevent damage, do not clean the interior using the following cleaners or techniques: . Never use a razor or any other

sharp object to remove soil from any interior surface.

. Never use a brush with stiff

bristles.

. Never rub any surface

aggressively or with too much pressure.

. Do not use laundry detergents or

dishwashing soaps with degreasers. For liquid cleaners, use approximately 20 drops per 3.8 L (1 gal) of water. A concentrated soap solution will create streaks and attract dirt. Do not use solutions that contain strong or caustic soap.

. Do not heavily saturate the upholstery when cleaning.

. Do not use solvents or cleaners

containing solvents.

Interior Glass To clean, use a terry cloth fabric dampened with water. Wipe droplets left behind with a clean dry cloth. If necessary, use a commercial glass cleaner after cleaning with plain water.

Caution

To prevent scratching, never use abrasive cleaners on automotive glass. Abrasive cleaners or aggressive cleaning may damage the rear window defogger.

Cleaning the windshield with water during the first three to six months of ownership will reduce tendency to fog. Speaker Covers Vacuum around a speaker cover gently, so that the speaker will not be damaged. Clean spots with water and mild soap.

Coated Moldings Coated moldings should be cleaned. . When lightly soiled, wipe with a

sponge or soft, lint-free cloth dampened with water.

. When heavily soiled, use warm

soapy water.

Fabric/Carpet/Suede Start by vacuuming the surface using a soft brush attachment. If a rotating vacuum brush attachment is being used, only use it on the floor carpet. Before cleaning, gently remove as much of the soil as possible: . Gently blot liquids with a paper towel. Continue blotting until no more soil can be removed.

. For solid soils, remove as much as possible prior to vacuuming.

To clean: 1. Saturate a clean, lint-free colorfast cloth with water. Microfiber cloth is recommended to prevent lint transfer to the fabric or carpet.

Chevrolet Impala Owner Manual (GMNA-Localizing-U.S/Canada-9086448) - 2016 - CRC - 5/20/15

Cleaning High Gloss Surfaces and Vehicle Information and Radio Displays Use a microfiber cloth on high gloss surfaces or vehicle displays. First, use a soft bristle brush to remove dirt that can scratch the surface. Then gently clean by rubbing with a microfiber cloth. Never use window cleaners or solvents. Periodically hand wash the microfiber cloth separately, using mild soap. Do not use bleach or fabric softener. Rinse thoroughly and air dry before next use.

Caution

Do not attach a device with a suction cup to the display. This may cause damage and would not be covered by the vehicle warranty.

2. Remove excess moisture by

gently wringing until water does not drip from the cleaning cloth. 3. Start on the outside edge of the

soil and gently rub toward the center. Fold the cleaning cloth to a clean area frequently to prevent forcing the soil in to the fabric.

4. Continue gently rubbing the soiled area until there is no longer any color transfer from the soil to the cleaning cloth. If the soil is not completely removed, use a mild soap solution followed only by plain water.

5.

If the soil is not completely removed, it may be necessary to use a commercial upholstery cleaner or spot lifter. Test a small hidden area for colorfastness before using a commercial upholstery cleaner or spot lifter. If ring formation occurs, clean the entire fabric or carpet. After cleaning, use a paper towel to blot excess moisture.

Vehicle Care

321

Instrument Panel, Leather, Vinyl, Other Plastic Surfaces, Low Gloss Paint Surfaces, and Natural Open Pore Wood Surfaces Use a soft microfiber cloth dampened with water to remove dust and loose dirt. For a more thorough cleaning, use a soft microfiber cloth dampened with a mild soap solution.

Caution

Soaking or saturating leather, especially perforated leather, as well as other interior surfaces, may cause permanent damage. Wipe excess moisture from these surfaces after cleaning and allow them to dry naturally. Never use heat, steam, or spot removers. Do not use cleaners that contain silicone or wax-based products. Cleaners containing these solvents can permanently change (Continued)
