If this vehicle has a tire sealant and compressor kit, there may not be a spare tire, tire changing equipment, and on some vehicles there may not be a place to store a tire. The tire sealant and compressor can be used to temporarily seal punctures up to 6 mm (0.25 in) in the tread area of the tire. It can also be used to inflate an under inflated tire. If the tire has been separated from the wheel, has damaged sidewalls, or has a large puncture, the tire is too severely damaged for the tire

Tire Sealant Read and follow the safe handling instructions on the label adhered to the compressor. Check the tire sealant expiration date on the sealant canister. The sealant canister should be replaced before its expiration date. Replacement sealant canisters are available at your local dealer. See “Removal and Installation of the Sealant Canister” following. There is only enough sealant to seal one tire. After usage, the sealant canister and sealant/air hose assembly must be replaced. See “Removal and Installation of the Sealant Canister” following. Using the Tire Sealant and Compressor Kit to Temporarily Seal and Inflate a Punctured Tire Follow the directions closely for correct sealant usage.

When using the tire sealant and compressor kit during cold temperatures, warm the kit in a heated environment for five minutes. This will help to inflate the tire faster. If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on the hazard warning flashers. See Hazard Warning Flashers 0 151. See If a Tire Goes Flat 0 284 for other important safety warnings. Do not remove any objects that have penetrated the tire.

. 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.

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.
