When It Is Time for New Tires
Various factors, such as maintenance, temperatures,driving speeds, vehicle loading, and road conditionsinfluence when you need new tires.
One way to tell when it istime for new tires is tocheck the treadwearindicators, which willappear when your tireshave only 1/16 inch(1.6 mm) or less of treadremaining.
You need new tires if any of the following statementsare true:
•You can see the indicators at three or more places
around the tire.
•You can see cord or fabric showing through the
tire’s rubber.
•The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
•The tire has a bump, bulge, or split.
•The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size orlocation of the damage.
The rubber in tires degrades over time, even if they arenot being used. This is also true for the spare tire, ifyour vehicle has one. Multiple conditions affect how fastthis aging takes place, including temperatures, loadingconditions, and inflation pressure maintenance. Withproper care and maintenance tires will typically wear outbefore they degrade due to age. If you are unsureabout the need to replace your tires as they get older,consult the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specific tires for yourvehicle. The original equipment tires installed onyour vehicle, when it was new, were designed to meetGeneral Motors Tire Performance Criteria Specification(TPC Spec) system rating. If you need replacementtires, GM strongly recommends that you get tires withthe same TPC Spec rating. This way, your vehiclewill continue to have tires that are designed to give thesame performance and vehicle safety, during normaluse, as the original tires.

{WARNING:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a jack
is provided with the vehicle, it is designed only for
changing a flat tire. If it is used for anything else,
you or others could be badly injured or killed if the
vehicle slips off the jack. If a jack is provided with
the vehicle, only use it for changing a flat tire.
This vehicle may come with a jack and spare tire or atire sealant and compressor kit. To use the jack andspare tire, follow the instructions below. To use the tiresealant and compressor kit, seeTire Sealant andCompressor Kit on page 6-71.
Tire Sealant and Compressor Kit
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 3-34.
{WARNING:
Over-inflating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor kit
instructions and inflate the tire to its recommended
pressure. Do not exceed the recommended
pressure.

Notice:Driving the vehicle through an automaticcar wash that has silicone carbide tire cleaningbrushes, could damage the aluminum orchrome-plated wheels. The repairs would not becovered by the vehicle warranty. Never drivea vehicle that has aluminum or chrome-platedwheels through an automatic car wash that usessilicone carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressingproducts on the vehicle may damage the paint finishand/or tires. When applying a tire dressing, alwayswipe off any overspray from all painted surfaceson the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metalrepair or replacement, make sure the body repair shopapplies anti-corrosion material to parts repaired orreplaced to restore corrosion protection.
Original manufacturer replacement parts will provide thecorrosion protection while maintaining the vehiclewarranty.
Finish Damage
Any stone chips, fractures or deep scratches in thefinish should be repaired right away. Bare metalwill corrode quickly and may develop into major repairexpense.
Minor chips and scratches can be repaired with touch-upmaterials available from your dealer/retailer. Largerareas of finish damage can be corrected in yourdealer’s/retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dustcontrol can collect on the underbody. If these are notremoved, corrosion and rust can develop on theunderbody parts such as fuel lines, frame, floor pan,and exhaust system even though they have corrosionprotection.
At least every spring, flush these materials from theunderbody with plain water. Clean any areas where mudand debris can collect. Dirt packed in close areas ofthe frame should be loosened before being flushed.Your dealer/retailer or an underbody car washing systemcan do this.

Rotation of New Tires
To maintain ride, handling, and performance of thevehicle, it is important that the first rotation service fornew tires be performed when they have 8 000 to13 000 km (5,000 to 8,000 miles). SeeTire Inspectionand Rotation on page 6-62.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. SeeEngine Oil onpage 6-13.An Emission Control Service.
When the Change Engine Oil Soon message displays,service is required for the vehicle as soon as possible,within the next 1 000 km/600 miles. If driving underthe best conditions, the engine oil life system might notindicate the need for vehicle service for more than ayear. The engine oil and filter must be changed at leastonce a year and the oil life system must be reset.Your dealer/retailer has trained service technicians whowill perform this work and reset the system.
If the engine oil life system is reset accidentally, servicethe vehicle within 5 000 km/3,000 miles since the lastservice. Reset the oil life system whenever the oilis changed. SeeEngine Oil Life System on page 6-16.
When the Change Engine Oil Soon message displays,certain services, checks, and inspections are required.
