Warning! G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
i
The flat tire may be transported in the
trunk when the retractable hardtop is
lowered. Use the protective sheet pro-
vided with the spare wheel. Do not ac-
tivate the tire inflation pressure
monitor until the deflated tire has been
removed from the vehicle.
