Consumer Description

Important: This is hybrid vehicle. With the cruise control set to maintain a constant speed and while descending a long hill, the vehicle speed is maintained using dynamic braking by charging the battery. But if the grade is long - such as on CA 101 just north of San Luis Obispo, (locally referred to as the Questa Grade) there will come a time when the battery “gas gauge” reaches 100 % at which time the dynamic braking ceases and without warning the vehicle’s speed gradually increases and can reach excess speeds. If you are not paying attention to the speedometer the speed can become excessive in a hurry.
