Driving and operating159ABS starts to regulate brake pressure
as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off, the system performs a self-test which may be audible.
Control indicator u 3 79.
Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS
are no longer available. During
hard braking, the vehicle can nolonger be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Electric parking brake
The electric parking brake can always
be activated, even if the vehicle is
switched off.
Do not operate electric parking brake
system too often when the vehicle is
switched off as this will discharge the 12 V vehicle battery.
In case of insufficient electric power,
the electric parking brake cannot be
applied or released.
Applying when vehicle is stationary9 Warning
Pull switch m for a minimum of
1 second until control indicator m
illuminates constantly and electric
parking brake is applied 3 79 . The
electric parking brake operates automatically with adequate force.
Before leaving the vehicle, check
the electric parking brake status.
Control indicator m 3 79.
1. Be sure the vehicle is at a
complete stop.
2. Pull switch m for approx.
1 second.
Page 162 of 273

160Driving and operatingThe control indicator m will flash and
then stay on once the electric parking brake is fully applied. Before leaving
the vehicle, check the control
indicator m to ensure the parking
brake is applied.
If the control indicator m flashes
continuously, then the electric parking
brake is only partially applied or there
is a problem with the electric parking
brake. A message is displayed in the
Driver Information Centre. Release
the electric parking brake and try to
apply it again. If the control indicator
m does not illuminate or keeps
flashing, seek the assistance of a
workshop.
Do not drive the vehicle if the control
indicator m is flashing 3 79.
If the electric parking brake is applied while the vehicle is moving, a chimewill sound and a message will be
displayed in the Driver Information
Centre. The vehicle will decelerate as
long as the switch is pulled.
Releasing the switch m during the
deceleration process will release the
parking brake. If the switch m ispulled until the vehicle stops moving,
the electric parking brake will remain
applied.
When the electric parking brake fault
indicator j illuminates, the electric
parking brake has detected a system
problem and is operating with
reduced functionality. To apply the
electric parking brake when j
illuminates, pull the switch m and
hold it until the control indicator m
remains on. If the control indicator j
illuminates, seek the assistance of a
workshop.
The vehicle may automatically apply
the electric parking brake in some
situations when the vehicle is not
moving. This is normal, and is done to periodically check the correct
operation of the electric parking brake
system.
If the electric parking brake fails to
apply, the rear wheels should be
blocked to prevent vehicle
movement.Releasing
1. Switch on the vehicle.
2. Keep brake pedal depressed.
3. Push switch m.
If attempting to release the electric parking brake without the brake pedal
being applied, a chime will sound and
a message will be displayed in the Driver Information Centre. The
electric parking brake is released
when m is off.
If control indicator j is illuminated, the
electric parking brake has detected a
system problem, and is operating with reduced functionality. To release the
electric parking brake when j is on,
push down the switch m and hold it
down until the control indicator j
goes off. If the control indicator
remains illuminated, seek the
assistance of a workshop.
Note
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to brake system parts. Make sure that
Page 163 of 273

Driving and operating161the parking brake is fully released
and the control indicator m is off
before driving.
Automatic release
The electric parking brake is
automatically released when the
vehicle is running, placed into gear
and an attempt is made to drive away.
Avoid rapid acceleration when the
electric parking brake is applied, to
reduce wear of parking brake lining.

Regenerative braking
Some braking energy from the
moving vehicle is turned back into
electrical energy. This energy is then
stored back into the high voltage
battery system, increasing energy
efficiency.
Regenerative power may be limited
when the high voltage battery is near
full charge or cold.Regeneration on demand
Regeneration on demand allows
increased deceleration by pressing
and holding the steering wheel
paddle. It works in D (Drive) and L
(Low). The accelerator pedal must be mostly released for it to work.
If regenerative braking is active, the regenerative active icon with arrowsis shown as green.
Regenerative braking 3 76.
Cruise control will switch off and the
brake lights may come on when this
feature is activated.
If the vehicle is in D (Drive) and is
brought to a complete stop while the regenerative braking paddle is held,
the vehicle will not creep forward
when the paddle is released. The
accelerator pedal must be pressed to
move the vehicle forward.
One-pedal driving 3 154.
If the vehicle is on a steep gradient,
the brake pedal will be required to
hold the vehicle.
The brake controller applies the
hydraulic brakes using a pump. You
may hear the pump during some
braking manoeuvres, such as rapid
brake application or during
regenerative braking as the vehicle
comes to a stop. This is normal
operation.
Hill Top ReserveHill Top Reserve enables you to
maximise regenerative braking
efficiency when driving from a higher
elevation immediately after charging.
When switched on, this feature will
stop the charging process before the

162Driving and operatinghigh voltage battery is full, allowing
space for energy from regenerative
braking.
This feature also integrates with the
Location-based charging feature,
allowing you to configure the system so it is enabled when you are at home ( On – home only ) or away (On – away
only ).
Location based charging 3 197.Ride control systems
Traction Control system The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC).
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, electric drive unit output is
reduced and the wheel spinning the
most is braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
TC is operational as soon as the
control indicator b extinguishes.
When TC operates b flashes.
