The daytime running lamps improve the visibility
of your vehicle during the day. To do this, the
daytime running lamps function must be
switched on using the on-board computer
(Y page 239).
If the engine is running and you turn the light
switch to 0060or0058, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps
Even if the light sensor does not detect that it is dark, the parking lamps and low-beam head-
lamps switch on when the ignition is switched on and the light switch is set to the 0058position.
This is a particularly useful function in the event
of rain and fog.
X To switch on the low-beam headlamps:
turn the SmartKey to position
0048in the igni-
tion lock or start the engine.
X Turn the light switch to 0058.
The green 0058indicator lamp in the instru-
ment cluster lights up.
Rear fog lamp
The rear fog lamp improves visibility of your
vehicle for the traffic behind in the event of thick fog. Please take note of the country-specific
regulations for the use of rear fog lamps.
X To switch on the rear fog lamp: turn the
SmartKey to position 0048in the ignition lock or
start the engine.
X Turn the light switch to 0058or0071.
X Press the 005Ebutton.
The yellow 005Eindicator lamp in the instru-
ment cluster lights up.
X To switch off the rear fog lamp: press the
005E button.
The yellow 005Eindicator lamp in the instru-
ment cluster goes out.
Parking lamps ! If the battery charge is very low, the parking
lamps or standing lamps are automatically
switched off to enable the next engine start.
Always park your vehicle safely and in a well lit area, in accordance with the relevant legal
stipulations. Avoid using the 0060parking
lamps over a period of several hours. If pos-
sible, switch on the right-hand 0064or left-
hand 0063 standing lamps. X
To switch on: turn the light switch to 0060.
The green 0060indicator lamp in the instru-
ment cluster lights up.
Standing lamps Switching on the standing lamps ensures the
corresponding side of the vehicle is illuminated.
X To switch on the standing lamps: the
SmartKey should not be in the ignition lock or in key position 0092in the ignition lock.
X Turn the light switch to 0063(left-hand side of
the vehicle) or 0064(right-hand side of the

Do not warm up the engine while stationary.
Pull away immediately. Avoid high engine
speeds and full throttle until the engine has

Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.

KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
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.
When you insert the Start/Stop button into the ignition lock, the system needs approximately
two seconds recognition time. You can then usethe Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
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.
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 78). Driving
135Driving and parking Z
You can execute a maximum of two consecutive
starting attempts via your smartphone. If you
insert the SmartKey into the ignition lock, you
can carry out two more starting attempts.
Once you have started the engine, you can
switch the engine off via your smartphone at any time.
You can only start the engine via your smart-
phone if:
R the SmartKey is in the ignition lock
R park position 005Dis selected
R the accelerator pedal is not depressed
R the anti-theft alarm system is not activated
R the panic alarm is not activated
R the hazard warning lamps are switched off

WARNING
Limbs could be crushed or trapped if the
engine is started unintentionally during ser-
vice or maintenance work. There is a risk of
injury.
Always secure the engine against uninten-
tional starting before carrying out mainte-
nance or repair work.
Make sure that the engine cannot be started via
your smartphone before carrying out mainte-
nance or repairs. You can prevent an engine
start via your smartphone if you:
R switch on the hazard warning lamps
R do not lock the doors
R open the hood Pulling away
General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position 003A or
0046, the vehicle could pull away sud-
denly. There is a risk of an accident.
When engaging transmission position 003Aor
0046, always firmly depress the brake pedal
and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature (Y page 240).
It is possible to shift the transmission from posi-
tion 005Dto the desired position only if you
depress the brake pedal. Only then is the park-
ing lock released. If you do not depress the
brake pedal, the DIRECT SELECT lever can still
be moved but the parking lock remains
engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con- verter to reach its operating temperature
more quickly.
