WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i You can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
i For optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position. Setting the center air vents

Start/Stop button General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS- GO function and a detachable Start/Stop but-
ton. A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example,
when starting the drive system.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
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 drive system starts
immediately.
To start the vehicle without actively using the SmartKey:
R the Start/Stop button must be inserted in
the ignition lock.
R the SmartKey must be in the vehicle.
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 73).
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. a mobile
phone or another SmartKey.
R with metallic objects, e.g. coins or metal
foil.
R inside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-
GO.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
R you will not be able to switch on the ignition
with the Start/Stop button.
R you will not be able to start the drive system
with the Start/Stop button until the vehicle is unlocked again.
If you lock the vehicle centrally using the but-
ton on the front door (Y page 80), you can
continue to start the drive system with the
Start/Stop button. Driving

The drive system can be switched off while

mal using the SmartKey.
You can only switch between Start/Stop but-
ton mode and SmartKey operation when the
vehicle is stationary.
You must also engage park position P.

You do not have to remove the Start/Stop
button from the ignition lock when you leave

WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment. 132
DrivingDriving and parking

Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the transmission out of park position P
R start the vehicle's drive system.
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.
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your vehicle may not be heard by other road users
in certain situations. This can happen, for
example, when you are parking and your vehi-
cle is not seen by other road users. This
requires you to adopt a particularly anticipa-
tory driving style, as it is necessary to allow
for the possibility that other road users may
behave erratically.
The vehicle is equipped with a sound gener-
ator. The sound generator is activated so that
other road users can hear your vehicle better. The sound generator is activated at speeds of under 20 mph (30 km/h) and switches off
automatically at higher speeds.
Starting procedure with the Start/Stop button The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
You can start the drive system if a valid key isin the vehicle. Switch off the drive system and
always take the key with you when leaving the vehicle, even if you only leave it for a short
time. Pay attention to the important safety
notes. X
Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once
(Y page 131).
The drive system is started. Once the vehi-
cle is ready to be driven, the Ready Readydisplay
(Y page 182) appears in the lower part of
the multifunction display.
Starting procedure with the SmartKey To start the drive system using the key
instead of the Start/Stop button, pull the
Start/Stop button out of the ignition lock.
X
Turn the SmartKey to position 3
(Y page 131 )in the ignition lock and release

The vehicle is equipped with a sound gener-
ator. At low speeds, an electric vehicle makes less noise than a vehicle with a combustion
engine. The sound generator is activated so
that other road users can hear your vehicle
better. The sound generator is activated at
speeds of under 20 mph (30 km/h) and
switches off automatically at higher speeds.

It is only possible to move the DIRECT SELECT
selector lever from position Pto the desired
selector lever position if you depress the
brake pedal. The parking lock is then deacti-
vated and the electrical parking brake is
released automatically. If the brake pedal is
not depressed, the DIRECT SELECT lever can still be moved but the parking lock remains
engaged.
Make sure that no charging cable is plugged
in. The parking lock cannot be released if a
charging cable is plugged in. Hill start assist
Hill start assist will aid you when pulling away
on a hill. It holds the vehicle for a short time
after you have removed your foot from the
brake pedal. This gives you enough time to
move your foot from the brake pedal to the
accelerator pedal and depress it before the
vehicle begins to roll. G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if: R you are pulling away on a level road or on a
downhill gradient.
