First Step

• When you're driving and feel the rumble of a flat tyre, slow down, turn on your hazard lights and try to park the caron level ground as quickly as possible.
• Put the automatic transmission into park and put the emergency brake on. If you have a manual transmission, leave it in first gear and pull the emergency brake.
• If you have to park on even a slight incline, try to find a heavy object to wedge up against the good tyres. This will help to keep the carfrom rolling when you have it jacked up.
• Once you've parked, take out the lug wrench, jack and the spare tyre from the trunk. Make sure the spare tyre has enough air in it.

Second Step

• Remove the hubcap and loosen the lug nuts.
• Pry off the hubcap with a screwdriver. Sometimes the lug wrench has a screwdriver at the end of it. If it does, use that. Some cars don't have hubcaps at all.
• Now use the lug wrench to loosen the lug nuts, which are the hexagonal bolts under the hubcap. If the lug nut has an L on it, turn clockwise. If it has an R or doesn't have anything on it, turn counterclockwise. Try to loosen the nuts an equal amount.
• Very important: Don't remove the lug nuts yet. Just loosen them.

Third Step

• Put the jack on the ground near the flat tyre, under the carframe. Make sure it is under something structural that can support the weight of the car.
• Start pumping the jack, so that the top of it reaches the bottom of the car. When it does, keep going until the flat tyre lifts off the ground. If the carseems unstable, lower the car, reposition the jack and try again.
• Very important: Never get under the car when it is jacked up.
