Brakes
87
BrakesIMPORTANT INFORMATION
Do not rest your foot on the brake
pedal whilst the vehicle is in motion.
Never allow the vehicle to coast
(freewheel) with the engine turned off.
The engine must be running to provide
full braking assistance. The brakes
will still function wi th the engine off,
but far more pressure will be required
to operate them.
If the red brake warning lamp
illuminates, safely bring the vehicle to
a stop, as quickly as possible and
seek qualified assistance.
Never place non-approved floor
matting or any other obstructions
under the brake pedal. This restricts
pedal travel and braking efficiency.
Driving through heavy rain or water can have
an adverse effect on braking efficiency. Under
such circumstances, it is recommended that
you lightly apply the brak es intermittently to
dry the brakes.
BRAKE WARNING LAMPS
Note: This warning lamp will also illuminate if
there is a fault with the parking brake. See 88,
ELECTRIC PARKIN G BRAKE (EPB).
ELECTRONIC BRAKE FORCE
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 heavily laden.
A fault with the EBD system is indicated by the
red brake warning lamp and the message EBD
FAULT . The braking system will still operate,
but without EBD assist ance. Seek qualified
assistance to have the fault rectified.
EMERGENCY BRAKE ASSIST (EBA)
The EBA system measures the rate at which the
brake pressure increases. If the system detects
an emergency braki ng situation, EBA
automatically initiates fu ll braking effect. This
can reduce stopping distances in critical
situations.
A fault with the EBA system is indicated by the
brake warning lamp illuminating and
Emergency Brake Assist Not Available
displaying in the message centre. The braking
system will still func tion, but without EBA
assistance. Seek qualified assistance to have
the fault rectified.
EMERGENCY STOP SIGNAL (ESS)
ESS (Emergency Stop Signal) automatically
activates the hazard warning lights during
emergency braking to warn other road users
and reduce the risk of a collision.
If the parking brake
is released and
this red warning lamp illuminates
while driving and/or the message
Brake Fluid Low is displayed in the
message centre, check the brake
fluid level at the earliest
opportunity and top-up as
required.
If this amber warning lamp
illuminates while driving and/or
ABS Fault is displayed in the
message centre, drive with extra
caution, avoid heavy braking
where possible, and seek qualified
assistance as soon as possible.

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.
If the parking brake is inadvertently applied
when the vehicle is moving at above 3 km/h
(1.8 mph), PARK BRAKE APPLIED is displayed
in the message centre, the warning indicator in
the instrument panel will illuminate and a
warning chime will sound.
If the parking brake is a pplied whilst the vehicle
is moving, releasing th e switch will disengage
the parking brake. The parking brake cannot be

CLEANING THE SENSORS
For reliable operation, th e sensors in the front
and rear bumpers should be kept free from ice,
frost and grime.
Do not clean the sensors with abrasive
or sharp objects or materials.
When using a high pressure spray, only
spray the sensors briefly, from a
distance greater than 200 mm
(8 inches).
PARKING AID SYSTEM FAULT
If the system has a fault when engaging reverse
gear or turning on the ignition, then a single, 3
second tone will be heard and a pop-up
warning will appear on the touch screen. If
both front and rear park ing aids are fitted, the
warning indicator in the parking aid switch will
flash for 3 seconds and then switch off.
If a fault is detected, the system is
automatically disabled.
Note: The parking aid may emit spurious tones
if it detects a frequenc y tone using the same
band as the sensors (e.g. air brakes).
REAR VIEW CAMERA
It remains the driver's responsibility
to detect obstacles and estimate the
vehicle's distance from them when
reversing.
When Reverse ( R) is selected, the system uses
a camera to provide a wide-angle colour rear
view image on the touch screen.
The camera display has priority over the
parking aid display. To view the parking aid
display instead, or to cancel camera display at
any time, touch the display.
The display also incorporates graphic overlays,
indicating vehicle di rection, width and
proximity to surrounding objects. The camera image will not be displayed;
•
If Drive ( D) is selected and the vehicle
speed is greater than 16 km/h (10 mph).
• If Drive ( D) is selected for longer than 2
seconds.
A. Solid line: The projec ted wheel trajectory.
B. Dotted line: The safe working width of the
vehicle (including exterior mirrors).
C. Boot access guideline: Do not reverse
