Wipers and washers

WINDSHIELD WIPERS

Note: If the wiper blades do become
stuck, or jammed, an electronic cut-out
may temporarily halt the operation of the
wipers. If this happens, switch off the
wipers and the ignition. Clear any
obstructions, and free the wiper blades
before attempting to switch on the
ignition.

Wiper operation

The stalk functions are as follows when
placed in the shown positions:

1. Windshield wipers off and parked.

2. Intermittent wipe.

3. Normal wipe speed.

4. Fast speed wipe.

5. Intermittent wipe rotary collar.

CAUTIONS

Do not operate the windshield
wipers on a dry windshield. The
drag on the wiper mechanism may

cause damage.

In freezing, or very hot conditions
ensure that the wipers have not
stuck to the windshield before

operating. The drag on the wiper
mechanism may cause damage.

Remove any snow, ice, or frost,
from the windshield, around the
wiper arms and blades, and the

windshield scuttle before operating the
wipers. Snow and ice can cause damage
to the wiper mechanism if left uncleared.

Intermittent variable delay

When intermittent wipe 2 is selected, the
delay between wipes can be varied by
turning the rotary collar 5 to the required
delay position. Rain sensor wiper
operation is selected by turning the collar
to AUTO.

Note: If configured, the delay period for
each collar position (excluding AUTO),
automatically increases and decreases
with vehicle speed.

Flick wipe

Pull the stalk towards the steering wheel
for a single wipe. Holding the stalk in this
position will operate the wipers
continuously at normal speed until
released.

Speed dependant mode

If speed dependant mode is configured,
the operation of all wiper modes will be
affected by the vehicle speed.

Speed dependant mode becomes active
when the wipers are operating and the
vehicle speed exceeds 10 km/h (6 mph).
If the vehicle subsequently becomes
stationary, the wiper automatically
changes to the next lowest operating
speed. When the vehicle starts moving
again, the original wiper speed setting is
automatically restored.

Speed dependant mode can be
configured by your Jaguar Dealer.

RAIN SENSOR

When AUTO (turn the rotary collar 5 to
AUTO) and intermittent wipe 2 are
selected, the wipers will automatically
operate when rain falls on to the
windshield, or when moisture is present.

For the wipers to operate, the ignition
system must be in the ON position.

E91184

CAUTIONS

Ensure that AUTO is not selected
when entering a car wash or
damage to the wiper blades or

arms can occur as they will operate in the
car wash.

During frosty conditions ensure
that AUTO is not selected before
operating the ignition system as

damage to the wiper blades can occur
when the windshield is frozen.

Wipers and washers

Note: When starting a journey with a wet
windscreen, the rain sensing wipers may
not operate immediately when the
ignition system is switched ON.
Therefore, a flick wipe should be used to
clear the windshield of any moisture.

WINDSHIELD WASHERS

Program wash and wipe

Timed jet function: If timed jet function is
configured, the windshield washer jets
(located on the wiper arms) only spray on
the up stroke of the wiper arms. This
function can be configured by your
Jaguar Dealer.

With the stalk in the OFF or intermittent
position, the program wash and wipe
sequence is activated by pushing the
button on the end of the column switch.

Short press: The wipers will perform five
normal speed wipes, followed by a drip
wipe. The washer jets will spray on the
first two wipes.

Extended press: The wipers and
washers will operate continuously at
normal speed until the button is released.
When released, the wipers will complete
their current wipe and then complete
three further wipes, followed by a drip
wipe.

Drip wipe: If drip wipe is configured,
following completion of the program
wash and wipe cycles, the wipers will
pause for four seconds then complete a
drip wipe to clear any remaining drips
from the windshield.

This function can be configured by your
Jaguar Dealer.

Washer

If normal or fast wipe is selected,
pressing the program wash and wipe
button will operate the washer jets.
• Short press: The washer jets spray for

two wipes.

• Extended press: The washer jets

spray until the button is released or a
10 second timer has elapsed.

Note: If the button is pressed during the
up-stroke of the wipers, the washer jets
may spray for the completion of that wipe,
prior to spraying for the required number
of wipes or duration.

If the rotary collar is set to AUTO, the
wipers will operate until no moisture is
detected.

WARNING

Some windshield wash products
are flammable, do not allow
windshield wash to come into

contact with sources of ignition.

CAUTION

Only windshield wash products
which are approved for automotive
use should be used, and only in

accordance with the manufacturer's
instructions.

Note: If the low washer fluid warning is
ON, the windshield wipers will not
operate when program wash and wipe is
activated even though there may be
washer fluid remaining in the reservoir
and sprayed onto the windshield. This is
to prevent damage to the blades,
scratching of the glass, or smearing dirt
across the windshield. Flick wiper, normal
or fast operation, can be selected to clear
any spray from the windshield.

HEADLAMP WASHERS

Note: Telescopic headlamp powerwash
units are contained within the front
headlamp units.

If the ignition system is in the ON
position, dipped beam headlamps are
switched ON and there is sufficient fluid
in the washer reservoir, pressing the
program wash and wipe button will also
operate the headlamp powerwash;
directing two short bursts of washer fluid
onto the headlamps.

After the first headlamp powerwash
operation, the headlamp powerwash will
operate on every fourth press of the
program wash and wipe button, provided
that the headlamps are still switched ON
and a 10 minute timer has elapsed since
the last headlamp powerwash.

Note: The powerwash sequence is reset
when the headlamps or ignition is turned
OFF and ON again.

Note: The headlamp powerwash function
is inhibited when the low washer fluid
warning is on.

CHECKING THE WIPER
BLADES

Clean the blade edge by wiping with a
soft cloth or sponge, using warm soapy
water.

Windshield wiper blades - clean
and inspect

Grease, silicone and petrol-based
products impair the blade’s wiping
capability.

The wiping edge of the blades should be
checked, and cleaned periodically. Lift
the wiper blades clear of the windshield
and wipe the blades with a clean, soft
cloth moistened with water to which a
mild liquid detergent has been added.

If signs of hardness or cracking in the
rubber are found, or if the wipers leave
streaks or unwiped areas on the
windshield during use, then the wiper
blades should be replaced immediately
to prevent damage to the glass.

Note: The wiper arms have a restricted lift
of 10 degrees.

WARNING

Only use cleaning products which
have been approved for use on
automotive glass and rubber.

Inappropriate products can cause
smearing, and increase glare.
