KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and a detachable Start/Stop but-
ton.
The Start/Stop button must be inserted in the ignition lock and the SmartKey must be in the
vehicle.
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 engine starts immedi-
ately.
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 engine.
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 85).
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 engine with
the Start/Stop button until the vehicle is
unlocked again.
The engine can be switched off while the vehi-
cle 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 func-
tion.

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
(Y page 275).
If Start/Stop button :has not yet been
pressed, this corresponds to the key being
removed from the ignition. 150

General notes
Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicleis stationary.
Observe the legal requirements for the coun- try in which you are driving. Some jurisdic-
tions prohibit the driver from using a mobile
phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 ft (approximately 14 m) per
second. Drive sensibly – save fuel Observe the following tips to save fuel:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof racks when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
Certain engine systems are designed to keep
the level of poisonous components in exhaust fumes within legal limits. Driving tips
