REAR FOG LAMPS

Depending on market, the single rear fog
lamp is located on either the rear
left-hand or right-hand side of the
vehicle.The rear fog lamp can only be
switched on if the low beam headlamps
are on or if the side lamps and front fog
lamps are switched on.

Press the switch to turn on the rear fog
lamp. Pressing the switch again will turn
off the rear fog lamp.

Note:

Both front and rear fog lamps will be
turned off when the ignition system is
turned off, but will not be illuminated
when the ignition system is turned on
again.

The rear fog lamp should only be used
when visibility is severely restricted by
fog.

ADJUSTING THE HEADLAMPS

When touring in right-hand traffic
countries, use the beam adjustment
mechanism located within each
headlamp unit to alter the beam pattern
accordingly.

When this is moved it enables the vehicle
to be driven in opposite hand drive
markets without having to stick blanking
decals onto the headlamp lens.

To adjust the headlamp:

1. Remove the headlamp unit.

2. Twist counterclockwise and lift off the

rear headlamp unit cover.

3. Locate the adjustment lever, as

shown.

4. Move the lever fully downwards.

5. Refit the high beam cover and the

headlamp unit.

Remember to place the levers back in
their original position when you have
returned to your country of origin.

HEADLAMP LEVELLING

Auto headlamp levelling

Automatic levelling of the headlamps is a
feature which avoids dazzling oncoming
drivers. A control unit adjusts the aim of
the lamps during acceleration,
deceleration and vehicle load conditions.

HAZARD WARNING FLASHERS

The switch is in the centre console below
the touch-screen and operates with the
ignition ON or OFF. Use only in an
emergency to warn traffic of a vehicle
breakdown or approaching danger.

To operate: Press the switch; the
direction indicators, the instrument panel
green indicators and audible warning will
operate in unison. The switch icon will
flash in unison with the indicators.

To cancel: Press the switch again.

ADAPTIVE FRONT LIGHTING
SYSTEM (AFS)

The Adaptive Front Lighting System
(AFS) is designed to give the driver
improved visibility under varying driving
conditions.

The illustration shows the light spread of
a vehicle NOT FITTED with AFL 1 and a
vehicle FITTED with AFL 2.

The main light source consists of
bi-functional (high and low beam) xenon
projector units.

The projector units are swivelled left or
right to improve the light spread on bends
in the road.

Bi-Xenon lamps 3 provide significantly
improved visibility over halogen lamps 4.

Lighting

They also react dynamically in the vertical
plane to the vehicle’s braking or
acceleration to maximise headlamp
performance.

The units operate when the engine is
running and the lighting control switch set
to headlamps, or AUTO, if the ambient
light has fallen below a preset level.

The system takes inputs from the
vehicle’s road speed, steering angle to
determine the amount of horizontal
swivel. The amount of swivel is highest at
low speed, manoeuvring speeds and
reduces as speed increases.

If reverse gear is selected, the lamps
return to the central position and the
swivelling capability is disabled.

When the engine is started, the
headlamps can be seen to swivel as they
initiate a self-calibration cycle for a few
seconds.

Cornering or static bending lamps

Additional lighting comes from the
cornering or static bending lamps which
are angled outwards from the centre line
of the vehicle.

These lamps broaden the beam of the
headlamps when cornering during
normal night driving.

The illustration shows the light spread of
a vehicle NOT FITTED 1 with static
bending lamps and a vehicle FITTED 2
fitted with static bending lamps.

Lighting

The system switches on the lamp if it has
received an input from the vehicle’s
direction indicator. As the system is
ignition based, the lamp will not stay on
even if the vehicle is parked with the
direction indicator lever in the operating
position.

Only the lamp on the same side as the
operating direction indicator illuminates.

Note: Excessive rotation of the steering
wheel while the ignition system is in the
OFF position may cause incorrect
calibration of the static bending lamps. In
extreme situations the lamps may operate
earlier than previously experienced.
However, correct calibration of the lamps
is automatically re-established within 30
seconds of the vehicle being driven.

If a system fault is detected the
headlamps will attempt to
move to the central position,

and remain stationary. The AFS warning
indicator will illuminate to indicate that a
fault is present.

If the warning indicator illuminates,
contact your Jaguar Dealer as soon as
possible.

DIRECTION INDICATORS

The direction indicators operate only
when the ignition system is ON.

The left column stalk has two positions
for indicating left or right turn.

The first position, moving the stalk up or
down, causes the indicator to flash while
it is held in this position.

The second position is a full movement of
the stalk up or down to indicate for a right
or left turn, which can then be released.
The indicators will remain flashing and
will cancel when the turn is completed.

An audible ticking and a flashing green
arrow on the instrument panel indicates
that the selected direction indicator is
ON.

Note: Should a direction indicator bulb
fail, the corresponding side green
warning indicator will flash at twice the
normal rate. The audible ticking will sound
at twice the normal rate.

Lane change flash

Move the left column stalk partially up or
down against spring pressure, then
release, to indicate a lane change. The
relevant direction indicator flashes three
times.
