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

PRINCIPLE OF OPERATION
Note: Once the system has been activated by
selecting reverse or using the switch, the front
and rear sensors are active when the gear
selector is in neutral. Therefore, if an obstacle
is detected an audible warning tone will sound.
The parking aid is automatically in standby
when the ignition is on and provides the driver
with information on most obstructions, and
their distance from the vehicle, when
manoeuvring. This is ac hieved by using four
ultrasonic sensors on each bumper.
When objects are detected the Park aid will
emit a warning tone which increases in
frequency and then becomes constant, as the
vehicle gets closer to the object.
USING THE PARKING AID
Touch-screen
To set the volume of the parking aid warning
tones:
• Select Vehicle from the touch-screen
Home menu, then select Veh. settings.
• Select Parking , then select Vol. presets.
Touch the Parking aid + or - button to increase
or decrease the warning tone volume.
Note: This adjusts both front and rear speaker
volume.
WARNINGS
It remains the driver’s responsibility
to be vigilant when reversing. Small
children or animals may not be
detected by the system.
It remains the driver’s responsibility
to detect obstacles and estimate the
vehicle’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.
CAUTIONS
Objects moving away from the vehicle
will be reported. Howe ver, whilst driving
away, object warning may be temporarily
reported due to ground reflection.
Systems using the same frequency
band as the front parking sensors, may
cause irregular tones to be emitted.

Parking aid

When the parking aid is active, a pop-up screen
is initiated displaying a plan view of the vehicle
and the immediate surrounding area. This can
be cancelled by touching the screen within the
pop-up area.
Note: If a rear-view camera is fitted, when
reverse gear (R ) is selected, the camera display
is selected automatically. To view the parking
aid display, touch the screen. The rear view
camera will indicate wh en a rear parking aid
sensor has been activated, by showing a red
panel over the relevant area of the camera
display. See Rear view camera (page 152).
Rear parking aid
The rear parking aid operates only with the
ignition is on and reve rse gear selected. If
obstacles are detected within operating range
(shown in next illustra tion), the parking aid
automatically provides an audible proximity
warning. 1.
Approximately 600 mm (24 inches).
2. Approximately 1800mm (71 inches).
Note: The outer rear sensors ( 1) will show
visual detection on the touch-screen, before
the audible warn ing is given.

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).

Rear view camera
152

PRINCIPLE OF OPERATION
The system provides a rear view image to
assist in reversing the vehicle.
The camera is positioned centrally and
unobtrusively, just above the rear license plate.
When reverse gear (R) is selected, the rear
view camera displays a wide-angle, colour view
from the rear of the vehicle, displayed on the
touch-screen. The camera display also incorporates graphic
overlays to aid the driver in assessing vehicle
direction, width and pr
oximity to surrounding
objects. These are detailed under Camera
overlays later in this section.
The camera display on the touch-screen has
priority over the parki ng aid display. To view
the parking aid display instead, touch the
touch-screen.
If a parking aid sensor is activated with the
camera in use, a corresponding red shaded
area will appear on the camera display to
identify which sensor has been activated.
To cancel the rear view camera display at any
time, touch the touch-screen.
The camera image will not be displayed when
any of the following apply:
• D is selected and the vehicle speed is
greater than 16 km/h (10 mph).
• D is selected for longer than 2 seconds and
the vehicle speed is less than 16 km/h
(10 mph).
WARNINGS
It remains the driver's responsibility
to detect obstacles and estimate the
vehicle's distance from them when
reversing. Some ov erhanging objects or
barriers, which could possibly cause damage
to the vehicle, may not be detected by the
camera.
Always be vigilant when reversing.

RUNNING-IN
Apart from a few precautionary
recommendations, there are no strict
running-in procedures for this vehicle.
By observing the following advisory
precautions you will ensure maximum engine,
transmission and brake life for your vehicle:
Engine
• Allow the engine to reach operating
temperature before operating at engine
speeds over 3 500 rev/min.
• Vary the speed frequently.
• From 1 500 kilometres (940 miles)
onwards, gradually in crease performance
of the vehicle up to the permitted
maximum speed.
Engine oil consumption
A certain amount of oil consumption is normal.
The rate of consumpt ion will depend on the
following:
• The quality and viscosity of the oil.
• Climatic conditions.
• The speed at which th e engine is being
operated.
• Road conditions.
Drivers should expect above normal
consumption when the engi ne is new, and after
running-in if high speeds are sustained.
Brakes
To ensure that brake pa ds reach their optimum
wear and performance condition, usually
within 500 kilometres (300 miles), it is
recommended that the following points are
observed.
• Where possible, avoid heavy or harsh
braking, as this can result in damage to the
brake pads and discs.
• Avoid prolonged use of the brakes
(e.g. when descending severe gradients).
• Frequent light application of the brakes is
desirable. This helps to fully bed-in the
brake pads.
These running-in guidelines also apply when
new brake discs or pads have been fitted.
Final drive unit
During the first 1 500 kilometers (940 miles):
•Avoid full throttle a pplications and do not
exceed 190 km/h (120 mph). Observe the
national speed limits in the country in
which you are travelling.
• Do not participate in motor racing events,
test track days, sports driving schools or
similar for the first 8 000 kilometers
(4 975 miles).

Driving hints

ECONOMICAL DRIVING
There are two main factors which influence fuel
economy, the way the vehicle is driven and
maintenance.
Driving tips for economy
•Avoid unnecessary jour neys, especially
short stop-start trips.
• Accelerate smoothly and gently from a
stand still.
• Allow time to brake gently and smoothly.
• Be aware of traffic and road conditions
ahead, and take action in time to avoid
hard braking or acceleration.
• When stationary apply the park brake, and
select neutral.
• Turn off the air conditioning when not
needed.
Maintenance and fuel economy
Regular servicing by a Dealer/Authorised
Repairer, along with regular checks by the
driver are essential fo r vehicle longevity and
fuel economy.
The condition of the engine (oils, filters, spark
plugs, settings etc.) tyre pressures, and wheel
alignment, will all have a bearing on fuel
economy. For this reason it is essential that the
vehicle is checked regularly by the driver and
serviced by an approved Dealer/Authorised
Repairer at the correct intervals.
Note: If you are in any doubt about the
maintenance requirement s, intervals, or
checks required, contact your Dealer/
Authorised Repairer for advice.
