2004 JAGUAR XJ sensor

4-24 On the Road
At dawn, as light increases, the sidelights
and headlights switch OFF automatically.
Do not cover the sensor and keep the
windscreen clean. Obstructing the light in
this area of the sensor may lead to
unwanted operation of the sidelights and
headlights.
Note:If the windscreen wipers are
switched on in auto, slow or fast modes
for more than 20 seconds then the
exterior lights will be switched on,
if selected to autolamps mode. The lights
will switch off 2 minutes after the wipers
are switched off or will go off straight
away if autolamps is deselected or the
ignition is turned off.
Exit delay
When parking the car at night, if the
headlights were switched on then they
will remain on for a short period after the
key has been removed from the ignition
switch. This is to give a clearly lit area for
occupants leaving the vehicle.
If the light switch rotary collar is in the
AUTO position there will be no exit delay
and the headlights will turn off when the
light switch is turned off. Three settings on the rotary collar set the
time that the lights will remain on after
the key is removed from the ignition
switch;
•10seconds.
•30seconds.
•2minutes.
Note:
The key must not be in the ignition
switch for this feature to operate.
The message centre shows the delay
setting or when this feature is turned off.
Headlight convenience
When approaching the vehicle,
the sidelights and headlights can be
switched on by pressing the headlight
button on the re mote transmitter.
The lights will come on for 25 seconds or
can be switched off by pressing the
remote transmitte r headlight button
again. Daylight running lights
In certain countries it is a legal
requirement for the lights to be on during
the hours of daylight.
With the rotary co
llar in the OFF
position, dipped headlights, sidelights,
tail lights, number plate lights and side
marker lights will switch on automatically
with the following conditions:
• The ignition is turned to position ‘II’.
• The vehicle gear se lector out of park.
• The parkbrake is not applied (released).

4-26 On the Road
Direction Indicators
The direction indicators, the left column
stalk, operate when the ignition is in
position ‘II’. Move the stalk up for
indicating a right turn or move it down to
indicate a left turn.
Two positions are provided. The first
position, partly moving the stalk up or
down, causes the indicator to flash while
it is held in this position. On releasing the
stalk the indicators stop flashing.
The second position is a full movement of
the stalk up or down, which can then be
released. The indicators will remain
flashing and will cancel when the turn is
completed. An audible ticking an
d a flashing green
arrow on the instrument cluster indicates
that the selected direction indicator is
operating.
Bulb failure
The direction indicators (including those
on a trailer, if attached) and side
repeaters are monitored for bulb failure.
If a bulb fails when it is on, a message is
shown in the message centre. At the same
time, the corresponding side green
warning light will flash at twice the
normal rate. The audible ticking will
sound at twice the normal rate.Door Guard/Puddle Lights
Door guard lights are fitted to each door
to give warning of an open door to
passing vehicles.
Puddle lights illuminate the ‘step out’
area at night.
Each light comes on automatically when
the door is opened. If the door is left
open the lights remain on for 5 minutes
and then switch off.
Approach Lights
Approach lights are fitted in the door
mirrors to provide illumination for the
floor area around the front doors.
The approach lights come on when:
• The vehicle is unlocked using a key, key transmitter or the central locking
switch.
• Using the headlight convenience button on the key transmitter.
• Reverse gear is selected.
The approach lights will not illuminate if
the autolamp sensor determines that the
ambient light is sufficiently bright.
Luggage Compartment
Lighting
The luggage compar tment will be
illuminated when the lid is opened.
Glove Compartment
The glove compartment will be
illuminated when the lid is opened.

On the Road 4 - 35
Park Distance Control
Caution: It remains the driver’s
responsibility to detect obstacles and
estimate the car’s distance from
them. Some overhanging objects,
barriers, thin obstructions or painted
surfaces which could possibly cause
damage to the vehicle may not be
detected by the system. Always be
vigilant when reversing.
Park distance control is always
automatically switched on when the
ignition is turned on.
Caution:
1. If, for example, you are driving into a confined space such as a
home garage, the outer sensors
will detect the side walls and after
3 seconds will switch the tone off.
However, as movement
continues, the inner sensors will
eventually detect the rear wall
and will start the tone again.
2. The sensors are not active when the gear selector is in neutral,
therefore, take care if moving the
vehicle as the tone will not be
heard.
3. Do not clean the sensors with abrasive or sharp objects. Note:
1. For reliable operation, the sensors in
the front (if fitted) and rear bumpers
should be kept free from frost, ice and
grime.
2. When using a high pressure spray the sensors should only be sprayed briefly
and at least 8 inches (20 cm) distance
from the sensors.
3. The front parking aid may sound spurious tones if it detects a frequency
tone using the same band as the
sensors.
Rear Park Distance Control
When reverse gear is selected and
ignition is on, rear park distance control
automatically provides an audible
proximity warning (to the nearest
detected obstacle) when reversing the
vehicle if obstacles are detected within
the operating range, shown in the
illustration above (between
approximately 24 inches [60 cm] ( A) and
63 inches [160 cm] ( B).

4-36 On the Road
Front and Rear Park Distance
Control
When both front and rear park distance
control are fitted, a switch is located in
the overhead console.
Pressing the switch turns front and rear
park distance control on or off together.
The switch integral warning lamp will
come on when the system is turned off or
if a fault is detected in the system.
A switch is not provided when only rear
park distance control is fitted.
Note: The front park distance control will
also operate when reverse gear is
selected. Front park distance control provides an
audible proximity warning when driving
forwards if objects are detected within
the operating range shown in the
illustration above (between
approximately 24 inches [60 cm] (
A) and
31 inches [80 cm] (C ) to the front of the
vehicle). The front sensors only operate
within a fixed speed range in forward
gears and are not effective when moving
forwards above 9mph (15km/h) or when
slowing down until below 4½ mph
(7 km/h).
If an obstacle is detected at the front or
rear of the vehicle, a beep tone will be
heard from the front or rear speaker
respectively, which increases in rate as
the vehicle approaches the obstacle. The front or rear park distance control
beep will become co
ntinuous when the
obstacle is detected at or within
12 inches (30 cm) from the rear or
approximate 10 inches (25 cm) from the
front of the vehicle.
If the system has a fault when engaging
reverse gear or turning on the ignition,
then a single, three second tone will be
heard (only once per ignition cycle) and,
if fitted, the switch lamp will come on.
The system is automatically disabled
when a fault is detected.

On the Road 4 - 51
Adaptive Cruise Control (ACC)
(Where fitted)
The adaptive cruise control system is designed to aid the driver
to maintain a gap from the vehicle ahead or a set road speed if
there is no slower vehicle ahead. The system is intended to
provide enhanced operation of th e vehicle when following other
vehicles which are in the same lane and travelling in the same
direction.
!WARNING:
Adaptive cruise control is not a collision warning or
avoidance system. Additionally , adaptive cruise control
will not detect:
1. Stationary or slow moving vehicles below 6 mph (10 km/h).
2. Pedestrians or objects in the roadway.
3. Oncoming vehicles in the same lane. The adaptive cruise control system is based on the use of a radar
sensor which projects a beam directly forward of the vehicle so
as to detect objects ahead. Th e radar sensor is mounted behind
a cover on the left-hand side of the lower cooling aperture,
to provide a clear ‘view’ forward for the radar beam.
• Only use adaptive cruise control when conditions are favourable, that is, straight, dry, open roads with light traffic.
• Do not use in poor visibility, specifically fog, heavy rain,
spray or snow.
• Do not use on icy or slippery roads.

4-52 On the Road
• It is the drivers responsibility to stay alert, drive safely and be in control of
the vehicle at all times.
• Keep the front of the vehicle free from dirt, metal badges or objects,
including vehicle front protectors,
which may prevent the sensor from
operating.
• Do not use ACC when entering or leaving a motorway.
The system is operated by switches
mounted on the steering wheel.
The driver can also intervene at any time
by use of the brake or accelerator pedals.
The steering wheel switches operate as
follows:
(A ) – RESUME: Resume set speed.
( B )– SET+ or SET–: Setthe speed(+) or
increase (+) or decrease (–) the set speed.
( C ) – CANCEL: Cancels without erasing
memorised speed.
( D ) – Gap increase or decrease. Setting a speed
Accelerate as normal
until the required
speed is reached.
Press the SET + butto n briefly and the
vehicle speed will then be stored in the
memory and the system engaged. The set
speed will be displayed on the message
centre.
Entering the follow mode
!WARNING:
When in follow mode the vehicle will
not decelerate automatically to a
stop, nor will the vehicle always
decelerate quickly enough to avoid a
collision without driver intervention.
Once a set speed has been selected,
the driver can release the accelerator and
the set road speed will be maintained.
SETSPEED 50 MPH

On the Road 4 - 55
Forward alert
Limited detection and warning of objects
ahead is provided during ACC operation
by the ACC ‘DRIVER INTERVENE’
warning.
The forward alert feature additionally
provides warnings whilst ACC is not
engaged, if an object is detected close
ahead then a warning tone and message
will be issued. The brakes will not be
applied.
This additional feature may be switched
on or off using the forward alert switch in
the lower outboard knee bolster
switchpack. When the indicator lamp in
the switch is on, forward alert is active.The sensitivity of the warning may be
changed:
• Pressing the gap decrease button
when ACC is disengaged displays and
then decreases the sensitivity of the
alert.
• Pressing the gap increase button displays and then increases the
sensitivity of the alert.
Both of these are accompanied by the
FORWARD ALERT message on
the message centre.
ACC failure
If a fault occurs during operation of the
system in cruise or follow modes,
the ACC system will switch OFF and
cannot be used until the fault is cleared.
A red warning light and the message
‘DRIVER INTERVENE’ appear briefly, and
are then replaced by an amber warning
light and the message ‘CRUISE NOT
AVAILABLE’.
If failure of the ACC or any related system
occurs at any other time an amber
warning light will be displayed
accompanied by th e message ‘CRUISE
NOT AVAILABLE’. It will not be possible
to activate the ACC system in any mode. Accumulations of dirt, snow or ice on the
on the sensor or cover may inhibit ACC
operation. Fitting of a vehicle front
protector or metallis
ed badges may also
affect ACC operation.
If this occurs in ACC cruise/follow mode,
the red warning light is displayed,
the audible alarm sounds and the
message ‘DRIVER INTERVENE’ appears
briefly. These warnings are then replaced
by the amber warning light and the
message ‘ACC SENSOR BLOCKED’ is
displayed. The system is no longer active.
Clearing the obstruction allows the
system to return to normal operation.
If the obstruction is present when ACC is
inactive, e.g. on initial starting or with the
ACC system switched off, the amber
warning light will be displayed with the
message ‘ACC SENSOR BLOCKED’.
Tyres other than those recommended
may have different sizes. This can affect
the correct operation of the ACC.

Climate Control 5 - 3
5 Climate Control
Introduction
The cabin is supplied with filtered air
from a fully automatic electronic climate
control system with manual overrides.
Two systems are available:
• A two zone system which allows the front occupants to set individual
temperatures for the left and right
sides of the interior.
• A four zone system which allows front and rear occupants to set individual
temperatures, i.e. two front zones and
two rear zones.
Occupant controls
The main climate control panel is located
in the centre console above the radio and
audio controls. There are two types of
control panel for either two or four zone
systems:
• A dedicated control panel with LCD (liquid crystal display) screen
(see page 5 - 6).
• A multi-function touch control and display unit shared with navigation
and other systems. Where this control
unit is fitted, refer to the Jaguar
Touch-screen Handbook for the
detailed operating instructions. Where the four zone climate control
system is fitted, an additional control/
display panel for rear passenger use is
located at the rear of the centre console,
between the front seats.
Voice control
The climate control system may also be
operated by spoken commands if the
optional voice activation system is fitted.
For full information on the use of this
system refer to the JaguarVoice
Handbook.
Recommended Operation
Automatic climate control
Automatic climate control provides
efficient regulation of the vehicle
environment without constant
adjustments from the occupant.
Sensors inside the vehicle monitor
temperature, humidity and direct
sunlight. In response, the electronic
control system automatically adjusts the
heat input, blower speed, air intake and
airflow distribution so as to maintain the
selected temperature(s) and reduce
misting.
Automatic operation provides optimum
comfort under most driving conditions. It is recommended that automatic
control (AUTO) is selected as the
normal operating mode.
Use of air conditioning
Air conditioning is an integral part of the
climate control system, providing cooled
and dehumidified
air for occupant
comfort; the dry airflow is also effective
in preventing misting of the windows.
While the air conditioner can be
manually switched off, it is recommended
that it is used in all climatic conditions
throughout the year, preferably in AUTO
mode.
Close all windows and the sunroof when
the air conditioning is on to ensure
satisfactory operation.
Use of air recirculation
The air conditioner/heater system is
supplied with fresh air via an intake flap.
Closing the flap causes the air inside the
vehicle to be recirculated. This helps to
prevent unpleasant odours from being
drawn into the vehicle and also to
improve the performance of the air
conditioner in very hot conditions.
However, the use of recirculated air will
cause screen misting after a short period
and should only be used as necessary.
