Selector lever:
Gear selector positions are:
P Transmission mechanically locked, starting available * R Reverse gear N Neutral gear, no power to the rear wheels (starting available) D Drive gear, all 5 forward gears available (see Performance Mode Pushbutton) 4 Upshift to 4th gear only 3 Upshift to 3rd gear only 2 Upshift to 2nd gear only
Gearshift Interlock Manual Override*
The interlock system which locks the sele ctor in P and prevents the ignition key from being removed except when P is
selected, may be manually overridden in the event of an emergency.
1. 1. With the parking brake applied
2. 2. Remove the access blank using a suitable Torx bit
3. 3. Insert a small screwdriver into the vacated hole
4. 4. Push the screwdriver downwards, gently, and hold whilst simultaneously moving the selector from P towards R ,
but do not engage R until the tool has been removed
5. 5. An audible warning may be heard when operation 4 is carried out
6. 6. With the selector in N and the access bl ank replaced, the vehicle may be started
Range Selection
The selector lever transmits operator demand to the transmission and TCM by means of a cable and Dual-Linear
Switch (DLS).
The lever operates the transmission assemb ly selector shaft, only for P R N D , by means of a cable. Movement of the
lever across the gate to 4, 3 and 2 positions disengages th e cable from the selector lever and engages the DLS which
controls gear selection electronically.
Gear selector module:
Provides illumination of the decal relevant to the gear sele cted. This information is provided by CAN from the TCM. Illuminates the security system Active LED on the gear selector surround, in response to an output from the BPM.

9—Security system Active LED
Page 1502 of 2490

The performance mode pushbutton:
Is mounted on the 'J' gate surround. This 'push-on push-off' swit ch selects Normal or Sport mode ( push-on for Sport) Is illuminated when Sport mode is selected. Is hard-wired to the transmission control module.
With 'Normal' selected the transmissi on will start off in 2 nd gear with kickdown to 1 st being available.
'Sport' mode allows 1 st gear en gagement from rest and modifies values in the TCM shift point calculations to provide higher
upshift speeds and enhanced availability of downshifts.
Kickdown Switch
The kickdown switch:
Is floor mounted under th e accelerator pedal. Is operated by pressing the pedal beyond the full throttle position. Provides maximum acceleration on driver demand, by signalling the TCM to select the lowest gear to give maximum
wheel torque.
Gear selector interlock solenoid:
Prevents the gear selector lever from being moved from P , unless the ignition switch is in position II, and the brake
pedal is depressed.
Is controlled by an output from the BPM
Park position switch:
Is hard-wired to the BPM Detects when the gear selector lever is moved to the Park position

Parts List
The heater circuit 'scavenges' coolant from the engine cooling system by mean s of an electric water pump. The water pump
has a protection circuit to inhibit operation when the coolant temperature is <16°C; this is to prevent possible damage to
the impeller due to the presence of coolant borne ice particles. Coolant is drawn from the en gine system through the water
valve inlet port into the heater matrix. The coolant passes thro ugh the bottom section of the heater matrix from left to right
filling the end tank of the matrix before returning through the top half of the ma trix and through the outlet ports of the
water valve and back into the engine cooling system.
Non return valves are located in the heat er bypass hose and the hose between the water pump and valve. These valves are
required to prevent coolant flowing in th e wrong direction at low engine speeds and restrict convected flow through the
heater after the engine is switched off.
When the exterior ambient temperature is > 0°C the refrigerat ion system automatically operates cooling and dehumidifying
incoming air before it is re -heated by the heater matrix.
Water Valve Assembly
Location
The water valve assembly is located above the water pump, in the engine compartmen t and is secured to the firewall by a
bracket. The valve operates by means of an electrical solenoid which oscillates the valve stem between the inlet and outlet
ports.
When in automatic mode, the water valve duty cycle is influenced by the following inputs to the A/CCM:
Outlet air temperature 'Air off' heater matrix temperature External ambient Coolant temperature
