QX55 Sales Certification Practice Test

The inclusion of INFINITI's vehicle security system as a standard feature on the QX55 provides a robust layer of protection against theft. This system typically incorporates various components such as an immobilizer, which prevents the engine from starting without the proper key or fob, making it significantly harder for unauthorized individuals to steal the vehicle. Additionally, this security system often includes sensors that detect unauthorized access and attempts to break into the vehicle, which can trigger alarms or notifications.

While other options may represent features associated with vehicle security, they do not encompass the complete range of protective elements found in the INFINITI vehicle security system. Elements such as mobile tracking devices or remote engine start disabling could be considered supplementary features but are not necessarily standard across all models. Alarm system activation is certainly important; however, the comprehensive nature of the vehicle security system covers more than just alarms, providing overall deterrence against theft effectively.
