Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can

for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and n on-slippery surface and apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
