Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
When a door is opened, the side window on that
side opens slightly. When the door is closed, the side window closes again.

Opening and closing
!Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper- ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!During a cold start with low engine oil tem-
peratures (below 32 ‡) (0 †), the maximum
engine speed is restricted in order to protect the engine. To protect the engine and main-
tain smooth engine operation, avoid driving at
full throttle when the engine is cold.
SmartKey positions
Start/Stop button
General notes
All vehicles are equipped with a Start/Stop but-
ton.
The Start/Stop button is located in the center
console and is illuminated when the vehicle is
unlocked.
The SmartKey must be in the vehicle.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
If there is a SmartKey in the ignition lock, this
takes precedence over the KEYLESS-GO start
function.
To start the vehicle without actively using the
SmartKey:
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 61). Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of the Smart-
Key.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will not be able to start the engine with the
Start/Stop button until the vehicle is
unlocked again.
If you lock the vehicle centrally using the button
on the driver's door (
Ypage 67), you can con-
tinue to start the engine with the Start/Stop
button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.
Key positions with the Start/Stop button
As soon as the ignition is switched on, all the
indicator lamps in the instrument cluster light
up. Further information on situations where an
indicator lamp either fails to go out after starting
the engine or lights up while driving
(
Ypage 191).
If Start/Stop button :has not yet been
pressed, this corresponds to the SmartKey
being removed from the ignition.

XIf problems persist, have PARKTRONIC checked at a qualified spe-
cialist workshop.
Only the red segments in
the PARKTRONIC warn-
ing displays are lit.
PARKTRONIC is then
deactivated.The PARKTRONIC sensors are dirty or there is interference.
XClean the PARKTRONIC sensors (Ypage 237).
XSwitch the ignition back on.
The problem may be caused by an external source of radio or ultra-
sound waves.
XSee if PARKTRONIC functions in a different location.
Rear view camera
General notes

Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif the camera lens fogs up, e.g. when driving
into a heated garage in winter, causing a rapid
change in temperature
Rif the camera lens is dirty or obstructed
