Heated Rear Window (HRW)

The CCU controls the operation of the HRW. When the HRW switch, located on the centre of the fascia, is pressed and released a signal is sent to the CCU. With the ignition on, the oil pressure sense present (i.e. the engine running), the tail window not lower than the 'clear of seal' position and, on 3 door models the roof closed/on, the CCU will grant the HRW on. The CCU will energise the HRW relay for approximately 15 minutes after which the CCU will de-energise the HRW relay. A warning lamp in the HRW switch shows when the HRW is operating.

If the switch is pressed before the timed 15 minute period, the CCU will immediately switch off the HRW. Removal of any of the input signals to the CCU will also stop HRW operation. The HRW switch will require reselection to operate again.
