Maintenance and care initial adjustment is completed after driving over 65 km/h (40 mph) for 15 to 20 minutes. This system may not function properly under the following conditions: • Uneven tread wear. • Driving on loose or low traction surfaces such as gravel, snow or slush. • Using tire chains • Initial tire pressures out of specified range. • Two or more under inflated tires. • Sudden loss of tire pressure. • Vehicle speeds less than 30 km/h (20 mph), greater than 120 km/h (70 mph) or driving duration less than 10 miles. • Transporting a heavy load or towing a trailer. The low tire warning feature can be turned off by your dealer. Checking the tire pressure • Use an accurate tire pressure gauge. • Check the tire pressure when tires are cold, after the vehicle has been parked for at least one hour or has been driven less than 5 km (3 miles). • Adjust tire pressure to recommended specifications found on the Certification Label. Improperly inflated tires can affect vehicle handling and can fail suddenly, possibly resulting in loss of vehicle control. Tire rotation Because your vehicle's tires perform different jobs, they often wear differently. To make sure your tires wear evenly and last longer, rotate them as indicated in the scheduled maintenance guide. If you notice that the tires wear unevenly, have them checked. 233
