Alert description
The Tire Pressure Monitoring System (TPMS) sensor issues a soft warning, indicating the rear left tire is underinflated or is leaking air as the air pressure is slightly below the recommended cold pressure (RCP). This may lead to reduced tire adhesion and control.
Potential impact
As the air pressure of the tire is low, adhesion and control may be reduced. Excessive tire wear may also occur.
