climate control JAGUAR X308 1998 2.G Owner's Manual

8.8. Automatic
Symbol indicates when the control of , temperature, fan speed and air distribution are all in Auto mode.
9. 9. External
There are two modes of external ambient temperature selection;
Quick Display. Pressing the button for <1.5 seconds (con firmed by a single bleep) will display the external
temperature for 4 seconds.
Continuous Display. Pressing and holding the button fo r >1.5 seconds (confirmed by two beeps) displays the
external ambient temperature continuously, the value of which will be updated every 4 seconds given that vehicle
road speed is > 25 km/h. Pressing the button again fo r <1.5 seconds resets to the previous display.
• NOTE: Continuous external temperature display will be cancel led when the ignition is switched OFF but not during engine
cranking.
10. 10. A/C
This push-on / push-off button will either select or deselect (as indicated by the state lamp) the refrigeration system.
The refrigeration system is automatically engaged when the Auto button is pressed.
• NOTE: Interior misting of screens may be reduced by continuous operation of th e refrigeration system.
11. 11. Auto
When selected and the state lamp lit, A/C mode will be operat ional and control of vent outlet temperature, fans speed and
air distribution will be automatic.
AUTO mode will disengage should manual air distribution or defrost buttons be operated or the manual fan speed knob be
rotated.
• NOTE: Automatic temperature control is constantly main tained irrespective of selected manual overrides.
12. 12. Defrost
Push-on push-off button, which when engaged will direct all air to the front and side glass at maximum fan speed. The
heated windshield (if fitted) will also be energized for a timed cycle of 6,5 minute s, but may be cancelled by pressing the
HEATED WINDSHIELD (F) button. Pressing 'DEF' again will retu rn to the last setting with automatic temperature control
being maintained.
Directing warm and humid air onto a cold screen can produce interior misting of screens. Operating the climate control
system without the refrigerati on system operating will exacerbate this problem.
• NOTE: Directing cold air onto the screen in warm humid conditions can produce external condensation.
13. 13. Heated Windshield (F)
Pressing the heated windshield button (whe re fitted) will energize the electrically heated windshield elements for a timed
cycle of 6,5 minutes; pressing the button again will cancel the request. Should the engine stall or the ignition be turned
OFF, the timer will be cleare d and the function cancelled.
• NOTE: The heated windshield may be activated with the cl imate control system OFF but the engine must be running.
In very cold ambient temperatures, icing of the interior of the glass is possible when the climate control system is operating
in AUTO mode; to reduce this poss ibility the A/CCM provides automatic operation of the heated windshield.
With the following conditions met, the heated windshield will automatically energize but the state lamp will NOT be lit.

External temperature < -10 °C Vehicle speed > 65 km / h The first two conditions exist > 2 minutes. Engine speed > 50 revs / min
14. 14. Heated Backlight (R)
Pressing the heated backlight button will simultaneously energize the heater elements for timed cycles of;
21 minutes backlight 11 minutes exterior mirrors
Pressing the button again within the 21 minute timer will cancel the request.
If the engine is stalled, or the ignition switched OFF, the backlight and door mirror timers will be cleared, resulting in both
functions being switched off.
• NOTE: Both the backlight and door mirrors may be activated with the climate control system OFF, but the engine must be
running.
15. 15. Temperature Decrease
Pressing this button (BLUE symbol) decreases the interior temperature setting in 1° increments. Should the button be
pressed when the setting temperature is below the lower automatic control temperature limit, the display will indicate 'LO'.
16. 16. Temperature Increase
Pressing this button (RED symbol) will raise the temperature setting in 1° increments Should the button be pressed when
the setting temperature is above the upper automatic control temperature limit, the display will indicate 'HI'.

System Self-test
Control Panel Interrogation Procedure
The control panel has a self-diagnosis feature, and is capable of displaying and clearing stored fault codes.
Climate control is an integrated system, therefore it is recommended that the PDU is used for fault diagnosis. The fault
codes displayed with the control panel self -diagnosis feature are not as comprehensive as those of the PDU. The PDU will
display the relevant fault code, fault co de description and information of the system peripherals at the time the fault
occurred.
Fault Code Extraction and Deletion Procedure
Error information is stored in the A/CCM up to a maximum of 5 faults. Should a sensor fault occur there will be an audible
beep and the message Er will be displayed on the control panel display for 5 seco nds after ignition on. Please note that this
will happen only once in any ignition switch cycle. The error source may be accessed by the following procedure
This procedure must be completed through one complete cycle, 1 through 6
• NOTE: * Actuator codes do NOT equate to system fault codes.
• NOTE: Only codes 11, 15 and 21 (see Fault Code List ing) will cause audible beep and 'Er' display.
• NOTE: If '0' is displayed, there are no stored faul t codes, wait 30 seconds to allow system self-test.
The control panel display will flash repeatedly indicating a list of two digit numbers (see table for code analysis). Should a code be displayed accompanied by an audible beep, the fault is current and therefore still present within
the system. A code displayed without an accompanying 'bee p' indicates a fault had previously occurred but is not
present within the system.
• NOTE: It is advisable to check all areas indicated with cleared fault codes. Such faults may re-occur if intermittent
problems are present in the system.
To delete stored and cleared fault codes press 'R' and 'FAC E' buttons simultaneously. After investigating and correcting all stored faults, press the 'Push Off' button to restore normal operation with
default panel settings, ie AUTO at 24°C.

Health and Safety
It is the duty of both employer and employee to ensure safe working conditions and practices. Correct safety procedures
and equipment must be applied to any potential hazards that are notified, or identified by an operator.
Employees must observe local legislation go verning working conditions and practices at all times and must always act in a
responsible manner in the workplace. In the event of personal injury resulting from any workshop activity, medical help
should be obtained as soon as poss ible. Self-treatment other than by first aid, should not be attempted.
WARNING: READ AND UNDERSTAND WORKING PRACTICE S CONCERNING CLIMATE CONTROL SYSTEMS, SECTION
412, WITH SPECIAL REGARD TO: REFRIGERANT MUST NEVE R BE DIRECTLY VENTED TO ATMOSPHERE. ALWAYS USE
JAGUAR APPROVED RECOVERY / RECYCLE / RECHARGE EQUI PMENT, WEAR SUITABLE EYE AND SKIN PROTECTION AND
OBSERVE ALL APPLICABLE SAFETY REQUIREMENTS.
With the constant introduction of new materials in the manufacture of vehicles, an awareness of the potential risks and
appropriate precauti ons is important.
Notification of Hazards
Symbols, which convey important information, will be positioned at the beginning of any specific operation or text. Standard symbols will be used where repairs or service procedures ar e detailed. All symbols will conform to standard ANSI Z535.3
(American National Standards Institute). The surround shape of the symbol will indicate the basis of the message to be
conveyed (see top three elements of ?) The icon depicting the message will be within the surrounding shape. Once
nominated the icon will retain its meaning.
POTENTIAL RISKS
Paint
Organic solvents, found in paints, may caus e damage or severe irritation to liver, kidneys, digestive tracts and respiratory
system if inhaled over long pe riods of time. Prolonged exposure to isocyanate s can cause lung sensitization with asthma-like symptoms developing on subsequent exposure to even low concentrations of isocyanates. Solvent inhalation can cause
dizziness or loss of consciousness and inhalation of spray dust and sanding debris may cause lung damage.
Spillage or splashes of solvents, paint ac tivators and additives can cause dermatitis or eye injury. Contact with peroxide or
acid catalysts can cause serious burns.
Applied Heat (Welding)
There is considerable risk of damage to eyes and skin if welding or flame cutting is attempted without using the correct
protective equipment. Many materials or fluids within vehicles are highly flammable and toxic and dangerous fumes may
also be liberated if heat is applied to expanded foam, corr osion protection, trim and seat materials, paints containing
isocyanates, and adhesive and sealing compounds.
When heated to a temperature of 300°C, polyurethane based compounds may liberate small quantities of isocyanate. Many
types of nitrogen containing chemicals ma y be liberated as breakdown products which can contain isocyanates, oxides of
nitrogen and hydrogen cyanide.
Potentially toxic or asphyxiant fumes and gases produced when welding include zinc oxide from zinc coated panels, and
ozone gas from the MIG process.
Metal Repair
There is considerable risk of damage to eyes, ears and skin wh en cutting, forming, or dressing metal. Soldering operations
can also be hazardous due to heat generated fumes and the risk of skin contact with hot materials.
