Double overhead camshafts on each cylinder head operate the valves. For each cylinder head, an inverted tooth timing chain 
transfers drive from the crankshaft to the VCT (variable camshaft timing) unit on the front of each camshaft. Graded tappets 
enable setting of inlet and exhaust valve clearances. 
 
Each timing chain has a hydraulic tensioner operated by engine oil pressure. The chain tensioners incorporate a ratchet 
mechanism, which maintains tension while the engine is stopped to eliminate start-up noise. The chains are lubricated with 
engine oil from jets located at the front of the engine block. Nylon chain guides control chain motion on the drive side. VALVE TRAIN

Automatic braking is limited to approximately 30% of full pressure (0.3G deceleration) and is intended to provide a 
smooth, gradual deceleration in follow mode conditions. Harsh braking by the target vehicle or following the target 
vehicle down to very low speeds or to a halt will require driver override of the brakes. 
While the radar sensor detects moving and stationary targets for assessment of the environment ahead, the system 
does not react to or provide any control in situations other than follow mode conditions. Stationary or slow moving 
vehicles (below 10 km/h), pedestrians, objects on the road and oncoming vehicles in the same lane are not recognized. 
 
 
WARNING: The adaptive speed control system is not a collision warning or avoidance system and that, other than the 
limited conditions of follow mode, driver intervention will be necessary to control the vehicle speed. 
In follow mode, some situations may cause target ambiguities for the detection system. These situations include: 
The nearby presence of a third vehicle when driving on a line slightly offset to the target vehicle. 
Vehicles edging into the lane ahead which are not detected by the system until they have moved into the radar beam. 
 
On the approach to, or exit from a bend, a target vehicle may be lost or a new target acquired as vehicles ahead change their 
angular position with respect to the radar sensor. On a straight road, if the sensing vehicle is in follow mode below its selected 
set speed, losing the target vehicle will cause the sensing vehicle to accelerate to this set speed. This acceleration is 
undesirable either on, or entering a bend when the target is suddenly lost, and in this situation the system inhibits the 
resumption of the set speed. 
 
The speed control system compares vehicle speed data from the ABS system with the relative speed of an external object as 
detected by the radar sensor to ascertain whether the object is stationary or not. 
 
 
NOTE: If tires are fitted which are different in diameter from those specified for the vehicle, the vehicle speed calculated 
by the ABS will not be the true road speed. This situation may cause stationary objects to be falsely identified as moving 
vehicles and result in automatic deceleration on a clear road.

The functionality for each of the above warning indicators is described in the following sections: 
 
1 and 2. Turn Signal Indicators 
The turn signal indicators are controlled by the CJB on receipt of medium speed CAN bus signals from the instrument cluster.  
The instrument cluster outputs a voltage to the turn signal indicator switch. The switch contains resistors of different values. 
When the switch is operated in either the LH or RH direction, the voltage is passed to a ground connection in the instrument cluster which detects the reduced voltage supplied via the resistors. When the turn signal indicator switch is operated in the  
LH or RH direction, the instrument cluster detects the ground voltage and determines whether a LH or RH selection is made.  
The instrument cluster transmits a medium speed CAN message to the CJB for operation of the applicable turn signal indicators. The message can contain a number of states for each possible switch position and also an out of range low and 
high state for circuit faults and an initial value for the switch neutral position. The turn signal indicators are not subject to the 
3 second indicator check when the ignition is switched on. 
 
The RJB (rear junction box) software controls the flash rate of the warning indicator which sends 'ON' and 'OFF' signals to the 
instrument cluster which flashes the indicators in a green color. During normal operation, the warning indicator flashes slowly, 
accompanied simultaneously by a sound from the instrument cluster sounder. If a fault exists, the RJB transmits a message to the instrument cluster which responds by displaying an appropriate message in the message center. 
 
The hazard warning indicators are controlled by the CJB on receipt of a completed ground path from the hazard warning indicator switch. The CJB outputs a medium speed CAN message to the instrument cluster which operates both the LH and RH turn signal indicators simultaneously. The hazard warning indicators can operate with the ignition switched off, therefore the  
CAN message from the CJB will also carry a 'wake-up' message for the instrument cluster. 3. Brake Warning Indicator 
 
This warning indicator is displayed in a red or amber color (dependant on market) as a brake symbol in all markets except 
United States of America (USA) which have the word 'BRAKE' in place of the symbol. The indicator is controlled by high speed  
CAN messages from the ABS module and the parking brake control module. The indicator is illuminated in a red color for a 3 second indicator check when the ignition is switched on. 
 
The instrument cluster monitors the fluid level in the brake fluid reservoir using a hardwired level switch. If the fluid level falls 
to below a determined level, the switch contact is broken and the ABS module detects the low fluid level condition. The instrument cluster illuminates the warning indicator and simultaneously displays a 'BRAKE FLUID LOW' message in the 
message center. 
 
 
NOTE: If both the brake warning indicator and the ABS warning indicator illuminate simultaneously, a major fault in the brake system will have occurred. 
 
The warning indicator also displays parking brake status. When the parking brake is applied, the warning indicator will be 
illuminated by the instrument cluster and, if the vehicle is moving, the message 'PARK BRAKE APPLIED' will be also displayed 
in the message center in response to a CAN message from the parking brake control module.  
If a condition exists where the parking brake cannot be applied, the parking brake control module issues a CAN message to the instrument cluster which flashes the warning lamp on and off and is accompanied with a message 'CANNOT APPLY PARK BRAKE'. 
If a fault occurs in the parking brake system, the parking brake control module issues a CAN message to the              instrument cluster which illuminates the warning indicator and displays the message 'PARK BRAKE FAULT' in the message 
center. 
4. Forward Alert Indicator 
 
The forward alert system uses the components of the adaptive speed control system to alert the driver of the presence of a 
vehicle ahead. The system can be turned on and off using a switch located in the auxiliary lighting switch when the adaptive 
speed control system is off. The indicator is illuminated in an amber color for a 3 second indicator check when the ignition is 
switched on. 
 
The forward alert system is controlled by the adaptive speed control module. When the switch is pressed, the forward alert 
system is activated and the adaptive speed control module issues a forward alert active message on the high speed CAN bus to the instrument cluster. The forward alert icon in the instrument cluster will illuminate in an amber color and a 'FORWARD 
ALERT' message will be displayed in the message center. When the button is pressed a second time, the module issues a 
forward alert off CAN message. The forward alert system will be deactivated, the forward alert icon will go off and a message 'FORWARD ALERT OFF' will be displayed in the message center. 
5. Automatic Speed Limiter (ASL) Indicator 
 
The ASL is controlled by the ECM (engine control module). An ASL switch is located in the floor console, adjacent to the gear 
selector lever. When the ASL switch is pressed, this is sensed by the ECM which issues a high speed CAN message to the instrument cluster. The instrument cluster illuminates the ASL warning indicator in an amber color to show the driver that ASL  
is active. The driver sets the required speed using the speed control SET +/- switches on the steering wheel. The selected 
speed is shown by the message ' LIMITER SET XXX MPH / K/MH' in the message center. The indicator is illuminated in an  
amber color for a 3 second indicator check when the ignition is switched on. ASL can be deselected by pressing the ASL switch, 
by depressing the throttle pedal initiating kick-down or by pressing the 'cancel' switch on the steering wheel. The ASL indicator 
will go off and the message center will display the message 'limiter cancelled' for 4 seconds. If a fault occurs in the ASL 
system, the ECM will send a message to the instrument cluster to illuminate the ASL indicator and display the message 'LIMITER NOT AVAILABLE'.

the RCM and illuminated by the instrument cluster on receipt of high speed CAN bus messages. The safety belt warning indicator is not subject to the 3 second indicator check when the ignition is switched on. 
 
The operation of the passenger seat buckle switch is as described below with the exception that the instrument cluster must 
receive a hardwired signal from the belt minder control module to indicate that a passenger is occupying the seat. 
The safety belt warning indicator is subject to a timer. The warning indicator is activated when the following conditions exist: 
Ignition is switched on 
One of the front seat belts is unbuckled 
USA market only - 75 seconds has elapsed after ignition on mode is selected 
Vehicle is not in reverse gear 
Vehicle speed is more than 8 km/h (5 mph). 
 
Once the above parameters are met, the instrument cluster flashes the warning indicator at 2 Hz for 10 seconds accompanied 
by a simultaneous chime. After 10 seconds the chime ceases and the warning indicator is permanently illuminated for 20 
seconds. This sequence is repeated every 30 seconds until one of the following events occurs: 
300 seconds has elapsed 
The safety belt of the occupied front seats is fastened 
The ignition is switched to off mode 
The vehicle speed decreases to below 5 km/h (3 mph). 
 
 
NOTE: On USA market vehicles, the warning indicator in not permanently illuminated. 
 
The safety belt minder function cannot be disabled. The seat belt minder function can be disabled. 
Refer to: Safety Belt System (501-20A Safety Belt System, Description and Operation). 14. Side Lamp Indicator 
 
The instrument cluster controls the green colored side lamp indicator on receipt of a side lamp status message on the medium 
speed CAN bus from the CJB and the auxiliary junction box. The lighting switch on the LH steering column multifunction switch is connected to the instrument cluster. Selections using this switch are detected by the cluster which requests the side or 
headlamp operation via a message to the CJB and the RJB. The CJB and the RJB responds with a side lamp active message  and the cluster illuminates the side lamp indicator. The side lamp indicator is not subject to the 3 second indicator check when 
the ignition is switched on. 
15. High Beam Indicator 
 
The instrument cluster controls the blue colored high beam indicator on receipt of a high beam status message on the medium 
speed CAN bus from the CJB. The lighting switch on the LH steering column multifunction switch is connected to the  instrument cluster. High beam or flash selections using this switch are detected by the cluster which requests the light 
operation via a CAN message to the CJB. The CJB responds with a high beam active message and the cluster illuminates the high beam indicator. The high beam indicator is not subject to the 3 second indicator check when the ignition is switched on. 
16. Rear Fog Lamp Indicator 
 
The amber colored rear fog lamp indicator is controlled by the auxiliary junction box and illuminated by the instrument cluster 
on receipt of a rear fog lamp on message on the medium speed CAN bus from the RJB. The indicator is illuminated for as long as the rear fog lamps are active. The rear fog lamp indicator is not subject to the 3 second indicator check when the ignition is 
switched on. 
 
SPEEDOMETER 
 
The speedometer is driven by high speed CAN signals transmitted by the ABS module. The wheel speeds are measured by sensors reading the rotational speed of the rear wheels from toothed targets on the hubs. An average of the two wheel speeds 
are passed from the sensors to the ABS module in the form of pulsed signals. The ABS module converts these signals into a speed output on the high speed CAN to the instrument cluster. The same speed outputs from the wheel speed sensors are also used to calculate the distance the vehicle has travelled. 
 
TACHOMETER 
 
The tachometer is driven by an engine speed signal transmitted on the high speed CAN from the ECM. The signal is derived from the CKP (crankshaft position) sensor. The signal is received by the instrument cluster microprocessor and the output from 
the microprocessor drives the tachometer. 
 
FUEL GAGE 
 
The fuel gage is controlled by CAN messages from the RJB. The RJB reads the values output by the fuel level sensors every  131 ms and transmits a fuel tank contents value, corrected for battery voltage, in a CAN message to the instrument cluster. A fuel pump symbol is displayed to the left of the linear gage. An arrow above the symbol shows the driver on which side of the 
vehicle the fuel filler cap is located. Above the linear fuel gage, is a LCD (liquid crystal display) area which displays odometer 
and trip readouts. When a trip computer function is selected, these are replaced by a trip computer display for the trip function 
selected. 
 
LIQUID CRYSTAL DISPLAY

The odometer displays the total distance which the vehicle has traveled. This is calculated by the instrument cluster using 
wheel speed signals from the ABS module.  
The odometer can show 6 characters and distances up to 999,999 miles or kilometers. The total distance travelled is stored in a 
EEPROM (electrically erasable programmable read only memory) and the RAM (random access memory). This ensures that the 
total distance is not lost if the battery is disconnected. 
 
The odometer value is passed to other vehicle system modules on the medium speed and high speed CAN bus. This is used to record the total vehicle mileage for diagnostic purposes and when storing DTC (diagnostic trouble code)'s.
