Although Battery State of Charge (SOC) is full, Maximum Driving Distance Display shows 1 mile (1 km). • Although Battery SOC is full, the vehicle cannot drive using EV mode (using electric motor power only) and will use HEV mode (using both electric power and a gas engine. • This is caused by low ambient temperature and low battery temperature. EV mode is suspended until the battery warms up to protect it from degradation and the gas engine will power the vehicle. This is normal operation. If the battery pack is able to warm up, EV mode will start and the display will change to show the correct Maximum Driving Distance Display for EV mode.

SummarySome vehicles may exhibit poor hands-free liftgate operation after a Mazda genuine trailer tow hitch accessory installation. IMPORTANT: When a Mazda genuine trailer tow hitch is installed on a CX-90 equipped with hands-free liftgate function, the sensing area is reduced due to the mechanical structure of the hitch. The hands-free liftgate’s optimal sensing area below the rear bumper is shown in green boxes in the image below. Since the left side of the hitch has a 7-pin connector socket, the right side is the most ideal for hands-free operation. For safety, be extra careful performing the kicking motion around the hitch.
