Parking aid
150

Front and rear parking aid
When both front and rear parking aids are
fitted, a switch is located in the overhead
console.
Pressing the switch turns both the front and
rear parking aids on or off. The switch warning
indicator will come on when the system is
turned on. A switch is not provided when only
a rear parking aid is fitted.
Note: The front parking aid will also operate
when reverse gear is selected.
The front parking aid provides an audible
proximity warning when driving forwards or
reversing.
The front and rear sensors only operate within
a fixed speed range in forward gears and are
not effective when moving forwards above
15 km/h (9 mph). Objects are detected within the approximate
operating range from the
front of the vehicle,
as shown in the illustration above:
1. 600 mm (24 inches).
2. 1800 mm (71 inches).
3. 800 mm (31 inches).
If an obstacle is detected at the front or rear of
the vehicle, a warning tone will be heard from
the front or rear speaker respectively.
Note: The outer rear sensors ( 1) will show
visual detection on the touch-screen, before
the audible warning is given.
The warning tone increa ses in rate as the
vehicle approaches the obstacle.
CAUTION
The parking aid system automatically
switches off when the vehicle is moving
above 15 km/h (9 mph) in D, and will need to
be reselected when moving below 15 km/h
(9 mph).

Parking aid

The front or rear warning tone will become
continuous when the obstacle is detected at or
within 300 mm (12 inches) from the vehicle.
Note: The outer front and rear sensors will
switch off if the distance to an object increases
or remains constant for 3 seconds. The
sensors will reactivate automatically if a new
object is detected with in the operating range,
or if the distance to the original object reduces.
Rear fitted accessories
Particular care must be taken when reversing
with rear fitted accessories e.g. bicycle carrier,
as the rear park assist will only indicate the
distance from the bumper to the obstacle.
Cleaning the sensors
Do not clean the sensors with abrasive or sharp
objects or materials.
For reliable operation, th e sensors in the front
and rear bumpers should be kept free from ice,
frost and grime.
When using a high pressure spray the sensors
should only be sprayed br iefly and not from a
distance of less than 200 mm (8 inches).
System fault
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 a pop-up warning will
appear on the touch-scre en. If both front and
rear parking aids are fitted, the warning
indicator in the parking aid switch will flash for
three seconds and then switch off, if a fault is
detected.
If a fault is detected, the system is
automatically disabled.
The parking aid may sound spurious tones if it
detects a frequency tone using the same band
as the sensors (e.g. air brakes).

Towing
184

Diesel engine vehicles
The diesel engine management system
incorporates sensors to determine optimum
performance. It is also designed to protect the
engine when arduous conditions are
encountered during towing. When ambient
temperature exceeds 40°C (104°F), the engine
coolant temperature may increase above
normal operating level. If this occurs, the
management system will initiate a series of
actions to restore norma l operating conditions.
The actions may include:
• A message centre message.
• Engine performance reduction.
• Air conditioning syst em cycling. The
system temperature output will fluctuate
between hot and cold, in order to dissipate
engine heat. If engine overheat persists,
the air conditioning will move to
continuous heat output.
It is advisable to bring the vehicle and trailer to
a convenient stop and allow the engine to idle
until normal temperature is restored. Do not
turn off the engine.
Trailer electrical connection
Note: The rear parking sensors are
automatically disabled when the trailer
electrical conne ction is made using Jaguar
approved towing equipment.
The vehicle's electrical system has been
designed to support all towing requirements,
and comply with legal requirements for the
specific territory in which the vehicle is first
sold.
LEVELLING
To maintain vehicle stabilit y, it is essential that
the trailer is loaded so that it remains parallel to
the ground. This is particularly important when
towing twin axled trailers.
CAUTION
Only connect appr oved electrical
circuits, which are in good condition to
the trailer socket. Connecting incorrect, or
faulty circuits may seriously damage the
vehicle's electrical circuits.

Wheels and tyres

Note: Different types of tyre may affect the
performance of the TPM system. Always
replace tyres in accordance with
recommendations. See TYRE
SPECIFICATIONS - ARDUOUS TERRAIN
(page 239).
Your vehicle may be equipped with a TPM
System which monitors pressure in each tyre
(temporary use spare wheels are not fitted with
sensors and are conseque ntly not monitored).
Wheels fitted with a TPM system can be easily
visually identified by the external metal lock nut
and valve ( 1). All Jaguar n on-TPM system
wheels have a rubber valve fitted (2).
TPM system operation
The TPM system monitors pressure of the
tyres via sensors located in each wheel and a
receiver located within the vehicle.
Communication between se nsor and receiver
is via Radio Frequency (RF) signals.
The tyre pressure warning
comprises a yellow warning telltale
within the instrument panel, and
the associated messages within the message
centre. If the telltale light illu
minates, you should stop
and check your tyres as soon as possible and
inflate them to the recommended pressure as
stated on the tyre pressure placard. If low
pressure warnings occur frequently, the cause
must be determined and rectified.
When driving through variable climatic
conditions the TPM syst em warnings may be
intermittent.
Your vehicle will also indicate a TPM System
malfunction by initially flashing and
subsequent continuous illumination of the
warning telltale. A text message will
accompany the system malfunction and will
display TYRE PRESSURE SYSTEM FAULT . The
TPM system fault sequence will be activated at
every ignition cycle until the fault is rectified.
When a malfunction occurs, the system may
not be able to de tect or signal low tyre pressure
as intended.
TPM system malfuncti ons may occur for a
variety of reasons which may include other
radio frequency systems that could cause
interference or the installation of incompatible
replacement tyres on the vehicle.

Tyre pressure warning with speed
If the vehicle is to be driven at speeds in excess
of 160 km/h (100 mph), the tyre pressures
should be increased as stated in this handbook
or on the placard label. Failure to increase the
tyre pressures and driving in excess of
160 km/h (100 mph), will illuminate the yellow
warning telltale and display a text message
TYRE PRESSURES LOW FOR SPEED . In the
event of this warning be ing displayed, vehicle
speed should be reduced
Temporary use spare wheel and tyre
change
If the temporary use spare wheel is fitted the
system will automatically recognise the change
in wheel positions. The n after approximately
ten minutes of driv ing above 25 km/h
(18 mph), a message TYRE NOT MONITORED
will be displayed accompanied by illumination
of the warning telltale and the corresponding
block in the vehicle graphic.
The warning telltale will initially flash and will
subsequently revert to continuous illumination.
Extended use of the temporary use spare wheel
will produce an additional text message TYRE
PRESSURE SYSTEM FAULT .
This TPM system display sequence will be
activated at every ignition cycle until the
temporary use spare wheel is replaced by a
fully operational full size wheel and tyre
assembly.
Always replace the temporary use wheel before
having TPM system faults investigated. The
fault may well be rectified with the fitment of a
fully operational full size running tyre in lieu of
the temporary use spare wheel assembly.
Tyre changing
Always have your tyres serviced or changed by
a qualified engineer.
Care must be taken to avoid contact between
the bead of the tyre and the sensor during
removal and refitting of the tyre, otherwise the
sensor may become damaged and or
inoperable.
Sensors can be removed from the wheel by the
unscrewing of the va lve retention nut.
Replacement sensor
Should the sensor require replacing, it should
be carried out by a Dealer/Authorised Repairer.
A replacement sensor must be fitted to a
running wheel in order to be recognised by the
system. The vehicle needs to be stationary for
15 minutes during the se nsor fitment before
the system is ready to detect the new sensor.
The vehicle must be driven for a minimum of
fifteen minutes after the sensor change, and
then remain stationary for fifteen minutes to
activate full TPM system operation.
If the TPM system warning for any wheel does
not clear, even after ensuring correct inflation
and driving for more than ten minutes above
25 km/h (18 mph), you should seek qualified
assistance as soon as possible.
CAUTION
Valve stem seal, washer, nut, valve core
and cap should be replaced at every tyre
change. Valve stem seal, washer and nut must
be replaced if valve re tention nut is loosened.
Sensor units and nuts must be refitted using
correct torque figures and associated profile.
Damage to the vehicle may result if these
precautions are not taken.

THE NAVIGATION SYSTEM
Loading the navigation DVD
Note: Before use, ensure that the navigation
DVD player is loaded with the correct mapping
DVD for your country. The navigation DV
D player is located behind an
access panel on the left-hand side of the
luggage compartment. The trim panel will need
to be removed (as shown) to access the DVD
player.
• Turn on the vehicle ignition.
• Move the lock/unlock button to the unlock
position ( 1).
• Press the unload button ( 2) to eject a DVD,
if one is installed in the DVD player.
• Load the correct Navigation System DVD
with the printed side upwards.
• Move the lock/unlock button to the locked
position. Replace the access cover.
SATELLITE SIGNALS
The system uses signa ls from the Global
Positioning Syst em (GPS) satellites, which
allow the approximate posi tion of the vehicle to
be calculated. This is combined with
information from vehi cle sensors and data
from the Navigation DVD, to establish the true
vehicle position.
The navigation computer then integrates this
data with the information stored on the DVD,
enabling you to plan and follow a route to your
desired destination.
WARNING
In the interests of road safety, only
operate, adjust or view the system
when it is safe to do so.
JAG0840
CAUTION
Do not allow moisture, dirt or foreign
objects to enter the slot.

Navigation system

Digitised area
Ensure that you are using the latest version of
the correct DVD for your country.
Note: Your Dealer/Authorised Repairer will
have details of how to order DVD updates.
The navigation DVD provided, contains a
digitised street map. Larger cities and
boroughs are completely covered. The regional
and unclassified roads or access roads and the
town centre for smaller towns and boroughs
are included.
One way streets, pedestrian zones, turn bans
and other traffic regula tions are taken into
account as far as pos sible. There may be
discrepancies between the data on the
navigation DVD and the actual local situation,
due to temporary or permanent changes to
road systems and their traffic regulations.
If the vehicle battery ha s been disconnected, or
if the vehicle has been transported to a new
location on another vehicle (e.g. by trailer or
train), the navigation system may require
several minutes to iden tify the new position.
Errors in vehicle position
Under certain driving condi tions, it is possible
that the vehicle pos ition shown may be
incorrect. Some examples are shown below:
• Negotiating circular ramps in car parks.
• Elevated roads in proximity to other roads.
• Where two roads run parallel to each other.
• Driving on steep roads.
• When the vehicle is transported by ferry or
train.
• After the tyres have been replaced.
• When using snow chains.
• After the vehicle has been rotated on a
turntable.
• After vehicle battery removal or supply
fuse failure.
Reception of GPS signals
GPS signals are high ly directional and
reception may occasiona lly be interrupted.
Some examples of situations likely to cause
problems are shown below:
• Inside buildings
• Forest roads between mountains
• Between tall buildings
• Roads under cliffs.
The vehicle’s direction and speed sensors will
minimise any adverse effect on the operation of
the navigation system, if this should occur.
Normal operation will resume once the
obstruction has been passed.
