WARNING
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
WARNING
Follow recommended tire inflation pressures.
Do not underinflate tires .Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and resul tinsudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Display messages Possible causes/consequences and
