WARNING
A damaged regular tire with low or miss‐

such as steering and braking response. Run-
flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if
the vehicle is not equipped with run-flat tires.
Follow the information on run-flat tires and
continued driving with these tires.◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
1. Identify the damaged tire.
Check the air pressure in all four tires, e.g.,
using the tire pressure gage of a tire repair
kit.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform
the reset.
