The remote control has an operating
range of approximately 50 ft (15 meters).
This can fluctuate greatly as a
consequence of local conditions
(reflective or absorbing objects) and
interference emitted by other radio
transmission systems. Similarly, the
operating range fluctuates in line with
the direction from which the remote
control is activated.
To prevent theft, however, it is advisable
to only unlock the vehicle when you are
in close proximity to it. Locking and unlocking from the
outside

the key once.
All turn signal lamps flash once.
The driver’s door and the charge socket
flap are unlocked.

key twice.
All turn signal lamps flash once again.
The passenger door and the tailgate are
unlocked in addition to the driver’s door
and the charge socket flap.
X Global locking: Press button0004on the
key.
With the doors, the tailgate(s), and the
charge socket flap closed, the turn

To prevent an inadvertent lockout,
never leave your key lying in the vehicle.
Drive lock function The vehicle locks automatically when the
ignition is switched on and the wheels are
turning at vehicle speeds of approximately
8 mph (14 km/h) or more. The drive lock
function is enabled at the factory.

WARNING
When leaving the vehicle, always remove the
key from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.
You can lock and unlock the vehicle from
inside using the central locking or
unlocking switch. This can be useful, for
example, if you want to unlock the
passenger door from inside or lock the
vehicle before starting to drive. Opening and closing

WARNING
The operating condition of the high-
voltage battery (e.g. not yet at normal
operating temperature or fully charged)
influences the braking effect of the
electric motor.
In overrun or braking mode, the motor's
braking effect may therefore be reduced or
may not be present at all.
As a result of the reduced engine braking
effect, you may cause an accident and
injure yourself or others.
Compensate for the reduced engine braking
effect by pressing the brake pedal
accordingly, as required.
! Do not hang any objects on the power
gauge.
This could cause the power gauge to be
torn from its mountings and be damaged.
Power gauge 0003contains two segments:
R Section right of 0
Power gauge 0003indicates the current
power that the drive system delivers to
the rear wheels. 100 % correspond to
55 kW peak power.
R Section left of 0
When you release the accelerator pedal
or when you depress the brake pedal, the
electric motor operates as a generator.
Electric current is produced and stored
in the high-voltage battery. As long as
the high-voltage battery is being
charged, the electric motor simulates an
engine brake.
When the pointer of power gauge 0003is in
the "OFF “position, the vehicle is not ready
to drive, because:
R the drive system has not been started
R the gear selector lever has not been
moved to position Nor Pwhen starting
the drive system R
the charging cable is connected to the
vehicle
R there is not enough power from the high-
voltage battery
R a problem occured in the high-voltage
system
After the drive system has been started, the
pointer of power gauge 0003moves to
position 0.READY appears in the
multifunction display (Y page 82). The
vehicle is ready to drive. Adjusting instrument cluster

WARNING
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill and operate the system only when
road and traffic conditions permit. Always
pay full attention to traffic conditions
first before operating system controls
while driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering adistance of 44 feet
(approximately 14 m) every second. G
WARNING
Always select a volume that allows you to
still hear ambient sound in your immediate
vicinity (e.g. horns, emergency rescue
vehicles, police vehicles, etc.). You could
otherwise cause an accident. G
WARNING
If you wish to have an audio system other
than an original smart audio system fitted
in your vehicle, please always have the
necessary work performed at an authorized
smart center.
This is particularly important if your
vehicle is fitted with a radio
preinstallation. Improper connection can
result in the failure of important vehicle
functions, thereby endangering the
operating safety of your vehicle and thus
your own safety and that of other people. Audio system*

responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination
of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction. i

Restarting the TPMS G
WARNING
It is the driver’s responsibility to
calibrate the TPMS on the recommended
cold inflation pressure. Underinflated
tires affect the ability to steer or brake
and might cause you to lose control of the
vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted when you have
adjusted the tire inflation pressure to a
new level (e.g. because of differen tload or
driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures. 126
