Sport
This mode combines the power of the combustion engine and the electrical
engine for a dynamic driving style.
Hybrid
Hybrid mode focuses on optimising
the vehicle's fuel consumption.
Combustion engine and electrical
engine operate together or in
alternation depending on driving
conditions and driving style.
Electric
In this mode, the vehicle is driven by
the electric engine only. Electric
mode is the default mode.Electric propulsion is available for
speeds below 84 mph.
All-wheel drive
The all-wheel drive system enhances
driving characteristics and stability,
and helps to achieve the best
possible driveability.
In all-wheel drive mode, the front axle is driven by the combustion engine or
the electrical engine, the rear axle is
driven by a second electrical engine.
Driving and operating153Fault9Warning
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 no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.

Driving and operating155Functionality check
When the vehicle is not moving, the
electric parking brake might be
applied automatically. This is done to
check the system.
Fault
Failure mode of electric parking brake
is indicated by a control indicator j
and by a vehicle message which is
displayed in the Driver Information Centre.
Vehicle messages 3 106.
Control indicator j flashes: electric
parking brake is not fully applied or
released. When continuously
flashing, release electric parking
brake and retry applying.
Brake assist If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintended
movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.
Regenerative braking
Regenerative braking generates
electrical energy resulting from
braking to charge the high voltage
battery. Regenerative power may be
limited when the high voltage battery
is fully charged.
If the selector lever is in D, energy is
recuperated when the brake pedal is
depressed.If the selector lever is in B, energy is
recuperated when the accelerator pedal is lifted.

194Driving and operatingThe counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection
The system monitors the driver's level
of vigilance. A camera at the top of the windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly
suited to fast roads (speed higher
than 40 mph).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.The driver drowsiness detection is
reinitialised when the ignition has been switched off for a few minutes or the speed remains below 40 mph for
a few minutes.
System limitations
In the following situations, the system
may not operate properly or even not operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
● dazzle caused by headlamps of an oncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roadsCharging9 Warning

Important information about
portable electric vehicle charging
● Charging an electric vehicle can stress a building's electrical
system more than a typical
household appliance.
● Before you plug in to any electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions and
protection devices) for heavy-
duty service at a 10 A continuous
load.
● Electrical outlets may wear out with normal usage or be
damaged over time, making them unsuitable for electric vehicle
charging.
● Check the electrical outlet / plug while charging and discontinue
use if the electrical outlet / plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.● When outdoors, plug into an electrical outlet that is weather-
proof while in use.
● Mount the charging cord to reduce strain on the electricaloutlet / plug.9 Warning
Improper use of portable electric
vehicle charge cords may cause a fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.
● Do not use extension cords, multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
● Do not use an electrical socket that is worn or damaged, or onethat will not hold the plug firmly
in place.
● Do not immerse the charging chord into any liquid.
