Brakes

During emergency braking conditions ABS
constantly monitors the speed of each wheel.
ABS varies the brake pressure to individual
wheels, according to the grip available. The
constant alteration of brake pressure can be
felt as a pulsing sensation through the brake
pedal. This is not a caus e for concern, as it is
designed to demonstrate to the driver that ABS
is operating.
ABS braking techniques
For optimum ABS performance, these
instructions on braking techniques during ABS
operation should be followed:
• Do not release the brake pressure when
the pulsating effect is felt. Maintain a
constant pressure until the manoeuvre is
completed.
• To familiarise y ourself with the feel of the
brake pedal during ABS braking, practise
an emergency stop pr ocedure, always
making sure it is safe to do so. With the
seat belts fitted to all occupants, drive the
vehicle at 32 km/h (20 mph) and brake
sharply.
• ABS enables the driver to steer around
obstacles during em ergency braking.
However, the consequences of turning
sharply at high speed cannot be overcome
by the ABS.
• Do not attempt to pump the brakes to
avoid skidding, as this can interfere with
ABS operation. The ABS will not allow the
wheels to skid under normal road
conditions.
• The ABS will tend to keep the vehicle
straight during braki ng. Because braking
distances may increase under certain road
conditions, it is nece ssary to plan and
make turning manoeuvres as early as
possible.
Electronic Brakeforce Distribution (EBD)
EBD balances the distribution of braking forces
between the wheels on the front and rear axles,
to maintain maximum braking under all vehicle
loading conditions.
For example; Under light loads, EBD applies
less braking effort to the rear wheels, to
maintain stability. Conv ersely, it allows full
braking effort to the rear wheels when the
vehicle is towing or is heavily laden.
A fault with the EBD system is
indicated by illumination of the red
brake warning indicator and the
message EBD FAULT is displayed in the
message centre. Gently stop the vehicle, as
soon as safety permit s, and seek qualified
assistance.

Brakes

Emergency Brake Assist (EBA)
The EBA system measures the rate at which the
brake pressure increases. If the system detects
an emergency braking situation, EBA
automatically init iates full braking effect. This
can reduce stopping dist ances in critical
situations.
EBA stops operating as soon as the brake pedal
is released.
EBA is part of the Dynamic Stability
Control (DSC) system and a fault
with the EBA system is indicated by
the amber DSC warning indicator illuminating
and DSC NOT AVAILABLE (with amber
backlight) displaying in the message centre.
Seek qualified assistan ce as soon as possible.
Brake vacuum assist
(V6 petrol models only)
When the engine is cold and/or engine vacuum
is low, Brake vacuum assist provides additional
brake pedal assistance. When the function is
operating, a pulsation ma y be felt through the
brake pedal - this is not a cause for concern.
A fault is indicate d by the message BRAKE
ASSIST FAULT (with amber backlight)
appearing in the message centre. Increased
brake pedal effort may be required to slow the
vehicle when the engine is cold and/or engine
vacuum is low. Seek qualified assistance.
ELECTRIC PARKING BRAKE (EPB)
The switch which operate s the parking brake is
mounted on the centre c onsole to the rear of
the gear selector.
To engage the parking brake (1): Pull the
parking brake switch up wards and release. The
switch will return to the neutral position. The
Parking brake warning and Brake fluid low
warning indicator on the instrument panel will
illuminate.
The Drive Away Release feature allows the
parking brake to release automatically as the
vehicle is driven away.
To disengage the parking brake (2): With the
ignition system on or with the engine running,
apply the foot brake and press the parking
brake switch down.
If the parking brake is a pplied while the vehicle
is stationary and D or R is selected, applying
the throttle will auto matically release the
parking brake.
The parking brake is also automatically
released when the gear selector is moved from
the P position.
WARNING
The EBA system is an additional
safety system; it is not intended to
relieve the driver of his or her
responsibility for exercising due care and
attention when driving.12

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).

Fuel and refuelling

Resetting the fuel cut-off
1.Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thor oughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualified advice and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
FUEL FILLER FLAP
Note: The fuel filler flap cannot be opened
when the alarm system is armed.
The fuel filler flap is located on the right-hand
side of the vehicle, at the rear.
1. Ensure that the vehicle is fully unlocked.
Push and release the rear of the flap (in the
area indicated in the illustration) to
unlatch.
2. Pull the fuel filler flap open. The label on
the inside of the flap indicates the correct
fuel for the vehicle. 3.
Twist the cap counte r-clockwise to undo.
4. Stow the cap on the lip provided on the top
of the hinge arm, as shown.
When replacing the cap, turn it clockwise until
the ratchet clicks. Failur e to do so could cause
the Engine malfunction warning indicator to
illuminate.
To close the filler flap, pus h the flap closed until
it latches.
WARNING
The fuel cut-off should never be reset
if you can smell fuel, or a leak can be
seen. Doing so can lead to a fire
which may cause persona l injury or death.
WARNINGS
Open the fuel filler cap slowly and
allow the pressure to release before
fully removing the cap to avoid fuel
spillage due to rapid expansion.
Take note of all warnings and
instructions given on the label affixed
to the inside of the fi ller flap. Failure to
do so may result in injury or death.

Towing

RECOMMENDED TOWING WEIGHTS
Nose/tongue weight must be the greater of
50 kg (110 lbs) or 7% of the actual trailer
weight, up to the maximum tow hitch load.
Nose/tongue weight can be measured using a
proprietary brand of nose weight indicator.
If it is necessary to increase the nose/tongue
weight up to the maximu m allowed, the vehicle
load should be reduced accordingly. This
ensures that the Gross Vehicle Weight (GVW),
and maximum rear axle load, are not exceeded.
Note: When towing the maximum permissible
gross vehicle weight can be increased by a
maximum of 100 kg (220 lb.) provided that the
road speed is limited to 100 km/h (60 mph).
Note: When calculating rear axle loading,
remember that the trailer nose/tongue weight,
the load in the vehicle's luggage area and the
weight of rear seat pa ssengers must all be
added together.
Towing weights - Australia only
The weight of a traile r must not exceed 1.5
times the towing vehicle’s weight. The
nose/tongue weight must be a minimum of 7%
of gross caravan/trai ler weight, up to a
maximum of 350 kg (722 lbs).
ESSENTIAL TOWING CHECKS
• The trailer should be parallel to the ground
when loaded and connected to the vehicle.
• When calculating the laden weight of the
trailer remember to include the weight of
the trailer, plus the weight of the load.
• If the load can be divided between the
vehicle and trailer, loading more weight
into the vehicle will generally improve
stability. Do not exceed the vehicle's
weight limits. See WEIGHTS (page 259).
• Ensure that all applic able regulations and
legislation are complied with when loading
and towing a trailer.
• Increase rear tyre pressures of the towing
vehicle to those for maximum vehicle
loading conditions.
• Ensure trailer tyre pressures are set to
trailer manufacturer' s recommendations.
• If the vehicle is loaded to maximum Gross
Vehicle Weight (GVW) the nose weight is
limited (see Towi ng weights table).
• Ensure that a suitable breakaway cable or
secondary coupling is used. Refer to the
trailer manufacturer' s instructions for
guidance.
• Ensure that the tow ball is secure.
• Check the operation of all trailer lights.
Maximum permissible
towing weights
Unbraked trailers 750 kg (1653 lb.) Trailers with
overrun brakes 1850 kg (4080 lb.)
Nose/Tongue weight 75 kg (165 lb.)
WARNING
Do not exceed the Gross Vehicle
Weight (GVW), m aximum rear axle
weight, maximum trailer weight, or
nose/tongue weight. Exceeding any of these
limits could cause inst ability and loss of
control. See WEIGHTS (page 259).
WARNING
Do not loop the breakaway cable over
the tow ball as it may slide off.

BRAKE FLUID CHECK
If the quantity of fluid in the brake
reservoir drops below the
recommended level, a red warning
indicator in the instrume nt pack will illuminate
and the message BRAKE FLUID LOW will be
displayed in the message centre.
Note: If the warning indicator illuminates or the
message is displayed, while the vehicle is being
driven, stop the vehicle as soon as safety
permits by gently applying the brakes. Check
and top-up the fluid level if necessary.
Checking the fluid level
With the vehicle on level ground, check the
fluid level at least every week (more frequently
in high mileage or arduous operating
conditions).
The brake fluid reservoi r is located beneath a
cover on the raised platform to the rear of the
main underbonnet area. See ENGINE
COMPARTMENT OVERVIEW (page 196).
1. Release the catch.
2. Lift the cover forwards, then pull
rearwards, to release the hinges.
3. Clean the filler cap with a clean, dry cloth
before removing, to prevent dirt or
moisture from entering the reservoir.
WARNING
Seek qualified assistance immediately
if brake pedal travel is unusually long,
unusually short or if there is any
significant loss of br ake fluid. Driving under
such conditions could result in extended
stopping distances or co mplete brake failure.
WARNINGS
Brake fluid is highly toxic - keep
containers sealed a nd out of reach of
children. If accidental consumption is
suspected, seek medical attention
immediately.
If the fluid comes into contact with
the skin or eyes, rinse immediately
with plenty of water.
Brake fluid is highl y inflammable. Do
not allow brake fluid to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine) - a fire
may result.
Do not drive the vehicle with the fluid
level below the MIN mark.

Wheels and tyres
222

Replacement tyres
Ideally, tyres should be replaced in sets of four.
If this is not possible, replace the tyres in pairs
(front and rear). When tyres are replaced, the
wheels should always be re-balanced and
alignment checked.
The correct tyre specification for your vehicle
can be found on the tyre information label.
Directional tyres
Directional tyres are designed to operate
correctly when rotating forwards (when the
vehicle is travelling forwards).
Typical direction indicators
WARNINGS
Do not fit cross-ply tyres.
Do not fit tubed tyres.
Do not swap tyres around the vehicle.
Tyres bed in to the specific
characteristics of each wheel
position. Swapping them around may affect
the vehicle's handling and traction.
Always fit replacement tyres of the
same type, and wher ever possible of
the same make and tread pattern.
Replacement wheels should be
genuine Jaguar pa rts. This will
maintain the designed driving
characteristics.
If the use of tyres not recommended
by Jaguar is unavoidable, ensure that
you read, and fully comply with, the
tyre manufacturers inst ructions. Failure to do
so, may lead to tyre failure due to incorrect
fitment or use.
