CHANGING A FLAT TIRE
If you get a flat tire while driving:
• do not brake heavily.
• gradually decrease the vehicle’s speed.
• hold the steering wheel firmly.
• slowly move to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrity of your tires.
