20Keys, doors and windowsBattery replacement in the electronic
key 3 17.
Electronic key synchronisation
The electronic key synchronises itself automatically during every starting
procedure.
Fault
If the central locking cannot be
operated or the propulsion system
cannot be started, the cause may be
one of the following:
● Fault in electronic key.
● Electronic key is out of reception range.
● The battery voltage is too low.
● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
To rectify the cause of the fault,
change the position of the electronic
key.
Manual unlocking 3 20.Memorised settings
Whenever the vehicle is switched off, the following settings are
automatically memorised by the
electronic key:
● automatic climate control
● lighting
● Infotainment system
● central locking system
● comfort settings
The saved settings are automatically
used the next time the vehicle is
switched on with the memorised
electronic key 3 19.
A precondition is that Personalisation
by driver is activated in the personal
settings of the Info Display. This must
be set for each electronic key which is used. The status change is available
only after locking and unlocking the
vehicle.
Vehicle personalisation 3 91.
Central locking system Unlocks and locks doors and load
compartment.A pull on an interior door handle
unlocks the respective door. Pulling
the handle once more opens the door.
Note
In the event of an accident in which
airbags or belt pretensioners are
deployed, the vehicle is
automatically unlocked.
Note
A short time after unlocking with the
remote control the doors are locked
automatically if no door has been
opened. A precondition is that the
setting is activated in the vehicle
personalisation 3 91.
50Seats, restraints
The front passenger airbag system
can be deactivated via a key-
operated switch on the passenger side of the instrument panel.
Use the key blade to change the
position:
* OFF:front passenger airbag is
deactivated and will not
inflate in the event of a
collision. Control indicator
OFF * illuminates
continuously in the
overhead consoleV ON:front passenger airbag is
active9 Danger
Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 53.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
If control indicator ON V illuminates
for a certain time after the vehicle is switched on, the front passenger
airbag system will inflate in the event
of a collision.
If both control indicators are
illuminated at the same time, there is
a system failure. The status of the
system is not discernible, therefore
no person is allowed to occupy the
front passenger seat. Contact a
workshop immediately.
Consult a workshop immediately if
neither of the two control indicators
are illuminated.
Change status only when the vehicle is stopped with the vehicle off.
Status remains until the next change.

zones and scroll through the different displays.
There are three display
configurations to choose from:
● Basic configuration displays the
speedometer with a simplified
high voltage battery gauge and
efficiency light.
● Standard configuration displays
the speedometer with a high
voltage battery gauge and
efficiency gauge.
● Enhanced configuration displays
the speedometer with high
voltage battery gauge, efficiency
ring, and power gauge.

OnStar services
General services
If you need any information e.g.
opening hours, points of interest and
destinations or if you need any
support e.g. in the case of a vehiclebreakdown, a flat tyre and low vehicle battery voltage, press Z to establish
a connection to an advisor.
Emergency services
In the case of an emergency situation,
press [ and talk to an advisor. The
advisor then contacts emergency or
assistance service providers and
directs them to your vehicle.
In the case of an accident with
activation of airbags or belt
tensioners, an automatic emergency
call is established. The advisor is
immediately connected to your
vehicle to see whether help is
needed.
Note
Establishing an emergency call may
not be possible in areas without
sufficient network availability or due
to hardware damage during an
accident.
Wi-Fi hotspot
The Wi-Fi hotspot of the vehicle
provides internet connectivity with a
maximum speed of 4G/LTE.Note
The Wi-Fi hotspot functionality is not available for all markets.
Note
Some mobile devices connect to Wi-
Fi hotspots automatically and use
mobile data capacity in the
background, even if they are not in
use. This includes automatic
updates, downloads, as well as
programme or app synchronisation
traffic. The data volume purchased
via OnStar might be consumed
rapidly. Turn off automatic
synchronisations in the settings of
your device.
Up to seven devices may be
connected.
To connect a mobile device with the
Wi-Fi hotspot:
1. Press j and then select Wi-Fi
settings on the Info Display. The
settings displayed include the Wi- Fi hotspot name (SSID),
password and connection type.
2. Start a Wi-Fi network search on your mobile device.

Daytime running lights
Daytime running lights increase
visibility of the vehicle during daylight.
While the daytime running light is
active, the tail lights and the sidelights are switched off.
Please remember that the low beam
should be switched on when required.
Hazard warning flashers Operated by pressing ¨.
In the event of an accident with airbag
deployment, the hazard warning
flashers are activated automatically.
Turn lightsstalk up:right turn lightstalk down:left turn light
A resistance point can be felt when
moving the stalk.
Constant flashing is activated when
the stalk is being moved beyond the
resistance point. It is deactivated
when the steering wheel is moved in
the opposite direction or stalk is
manually moved back to its neutral
position.
152Driving and operatingThe instrument cluster also displays
an active battery gauge when the
vehicle is ready to be driven.
A chime will sound if the driver's door is opened while the vehicle is
switched on. Always press
POWER m to switch off the vehicle
before exiting the vehicle.
If the vehicle will not start due to a low electronic key battery, the vehicle can
still be driven.
Operation in case of failure 3 149.
RestartingCaution
If the vehicle must be restarted
while it is still moving, move the
selector lever into N and press
POWER m twice without
depressing the brake pedal. The
propulsion system will not restart
in any other way.
Emergency shut off during driving
1. Brake using a firm and steady pressure. Do not pump the brakes
repeatedly. This may reduce
power assist, requiring increased brake pedal force.
2. Shift the selector lever into N. This
can be done while the vehicle is
moving. After shifting into N, firmly
apply the brakes and steer the
vehicle to a safe location.
3. Come to a complete stop, shift into P, and switch off the vehicle
by pressing POWERm.
4. Apply the parking brake. If the vehicle cannot be pulled
over and must be shut off while
driving, press and hold
POWER m for more than
2 seconds, or press twice briefly
within 5 seconds.9 Danger
Switching off the vehicle while
moving may disable the airbags.
While driving, only shut the
propulsion system off in an
emergency.
Starting the vehicle at low
temperatures
It is recommended to plug in the vehicle when exterior temperatures
are below 0 °C to maximise high
voltage battery life.
Should the exterior temperature be
lower than -32 °C, the vehicle must be
plugged in when the vehicle is
switched on.
Parking Note
Do not allow the vehicle to remain in
extreme temperatures for long
periods without being driven or
being plugged in.
