Maintenance and care SERVICING YOUR TIRES 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 3 hours or has been driven less than 5 km (3 miles). As you drive, the temperature in the tire warms up, increasing the tire pressure. • Adjust tire pressure to recommended specifications found on the Certification Label.
