The 2010 SRX is equipped with a standard Rear Safety Belt Reminder (RSBR) for all rear seat occupants.
Rear seat occupancy is determined based on the safety belt switches -- occupant sensing mats are not used -- and rear seat occupants are not detected until buckled. Therefore, if an occupant never buckles, the system will never detect the occupant's presence.
Buckled Safety Belt
If an occupant does buckle, the occupant is detected and the corresponding RSBR indicator on the instrument cluster will illuminate green for 35 seconds, and then turn off. (Fig. 1)
Once a rear seat occupant is detected, the system will assume that occupant is present for the duration of the ignition cycle or until a rear door is opened. If an ignition cycle occurs or a rear door is opened, the RSBR indicators will reset and assume no rear occupants are there until a safety belt buckle is latched again.
Unbuckled Safety Belt
If the rear seat occupant unbuckles during the same ignition cycle and the speed exceeds 6.5 mph (10kph), the RSBR indicator will illuminate red in full screen mode on the instrument cluster and the RSBR chime will sound. (Fig. 2)
The chime will stop after three seconds, but the RSBR indicator will remain illuminated until the rear seat occupant buckles or the ignition cycle ends. If the occupant rebuckles, the indicator will illuminate green for 35 seconds.
Safety belt latch plates and buckles are keyed, so they cannot be crossed. For example, the center plate will not latch into either of the side safety belt buckles.
RSBR Service
There are no DTCs associated with the RSBR system. The system can be diagnosed using the following symptom diagnostic procedure: Safety Belt Indicator Circuit Malfunction - Rear.
