All markets have a common wiper system with headlamp powerwash as an option.

The wipers system comprises two front wipers and one rear wiper which are powered by electric motors. A washer reservoir is located in the front left hand wheel arch and is fitted with two electric pumps. Each pump supplies washer fluid to either the front or rear screens. On certain models, a third pump can be fitted to operate a headlamp power wash function. Operation of the front and rear wipers and washers is controlled by the driver using switches located on a steering column stalk and push button switches on the fascia.

Control of the wipers and washers is achieved by the following components:
^ BCU.
^ IDM.
^ Front wiper relay.
^ Front wash/ wipe switch.
^ Variable delay switch.
^ Front wiper motor assembly.
^ Front washer pump motor.
^ Rear wiper relay.
^ Rear wiper switch.
^ Rear washer switch.
^ Rear wiper motor.
^ Rear washer pump motor.

Both the Body Control Unit (BCU) and the Intelligent Driver Module (IDM) control the wiper system. The BCU controls the time delay function of the wiper system and is located below and behind the passenger glovebox. During engine cranking the BCU prevents wiper functions. Two relays are located in the passenger compartment fusebox. The relays control the delay operation of the front and rear wipers. The relays are an integral part of the fusebox and cannot be renewed separately.

Power for the wiper system is supplied by the IDM, which is integral with the passenger fusebox and cannot be renewed as a component. A serial communication link allows communication between the IDM and the BCU.

The system has diagnostic capabilities through TestBook.
