2014 Chevrolet Express Owners Manual

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 just 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 brush attachment is being used during vacuuming, only use it on the floor carpet. Before cleaning, gently remove as much of the soil as possible using one of the following techniques: . 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. Rotate 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. Following the cleaning process, a paper towel can be used to blot excess moisture.

Cleaning High Gloss Surfaces and Vehicle Information and Radio Displays For vehicles with high gloss surfaces or vehicle displays, use a microfiber cloth to wipe surfaces. Before wiping the surface with the microfiber cloth, use a soft bristle brush to remove dirt that could scratch the surface. Then use the microfiber cloth by gently rubbing to clean. 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 warranty.

Additional Maintenance and Care Your vehicle is an important investment and caring for it properly may help to avoid future costly repairs. To maintain vehicle performance, additional maintenance services may be required. It is recommended that your dealer perform these services — their trained dealer technicians know your vehicle best. Your dealer can also perform a thorough assessment with a multi-point inspection to recommend when your vehicle may need attention. The following list is intended to explain the services and conditions to look for that may indicate services are required.

Battery The battery supplies power to start the engine and operate any additional electrical accessories.

To avoid break-down or failure to start the vehicle, maintain a battery with full cranking power. Trained dealer technicians have the diagnostic equipment to test the battery and ensure that the connections and cables are corrosion-free.

Belts . Belts may need replacing if they

squeak or show signs of cracking or splitting. Trained dealer technicians have access to tools and equipment to inspect the belts and recommend adjustment or replacement when necessary.

Brakes Brakes stop the vehicle and are crucial to safe driving. . Signs of brake wear may include

chirping, grinding, or squealing noises, or difficulty stopping. Trained dealer technicians have access to tools and equipment to inspect the brakes and recommend quality parts engineered for the vehicle.

Fluids Proper fluid levels and approved fluids protect the vehicle’s systems and components. See Recommended Fluids and Lubricants on page 11-12 for GM approved fluids. . Engine oil and windshield

washer fluid levels should be checked at every fuel fill. Instrument cluster lights may come on to indicate that fluids may be low and need to be filled.

Service and Maintenance

Hoses Hoses transport fluids and should be regularly inspected to ensure that there are no cracks or leaks. With a multi-point inspection, your dealer can inspect the hoses and advise if replacement is needed.

Lamps Properly working headlamps, taillamps, and brake lamps are important to see and be seen on the road. . Signs that the headlamps need

attention include dimming, failure to light, cracking, or damage. The brake lamps need to be checked periodically to ensure that they light when braking. . With a multi-point inspection,

your dealer can check the lamps and note any concerns.

Shocks and Struts Shocks and struts help aid in control for a smoother ride. . Signs of wear may include

steering wheel vibration, bounce/ sway while braking, longer stopping distance, or uneven tire wear.

. As part of the multi-point inspection, trained dealer technicians can visually inspect the shocks and struts for signs of leaking, blown seals, or damage, and can advise when service is needed.

Tires Tires need to be properly inflated, rotated, and balanced. Maintaining the tires can save money and fuel, and can reduce the risk of tire failure. . Signs that the tires need to be replaced include three or more visible treadwear indicators; cord or fabric showing through the

rubber; cracks or cuts in the tread or sidewall; or a bulge or split in the tire. Trained dealer technicians can inspect and recommend the right tires. Your dealer can also provide tire/wheel balancing services to ensure smooth vehicle operation at all speeds. Your dealer sells and services name brand tires.

Vehicle Care To help keep the vehicle looking like new, vehicle care products are available from your dealer. For information on how to clean and protect the vehicle’s interior and exterior, see Interior Care on page 10-91 and Exterior Care on page 10-86.
