fer to page 182.
Starting the engine Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the car unattended with the

Automatic Engine Start/Stop
Function
The concept
The Automatic Engine Start/Stop Function
helps save fuel and lower emissions. The sys‐
tem automatically switches off the engine dur‐
ing a stop, e.g., in a traffic congestion or at traffic
lights. The ignition remains switched on. The
engine starts again automatically when the
clutch is pressed.
Automatic operation
The automatic engine start/stop function is op‐
erational after each engine start. It is activated
whenever you drive forward faster than 3 mph/
5 km/h.
Automatic engine stop
The engine is switched off automatically during
a stop under the following conditions:▷Neutral gear is engaged and the clutch pedal
is not depressed.▷The driver's safety belt is fastened or the
driver's door is closed.
When the engine is switched off, the air volume
of the air conditioner or automatic climate con‐
trol is reduced.
Indicator lamp in the instrument cluster The indicator lamp lights up when the
Auto Start/Stop function is ready to
start the engine automatically.
More information, refer to page 186.
Note
The engine is not switched off automatically in
the following situations:
▷External temperatures below approx. 37 ℉/
+3 ℃.▷High external temperature and operation of
the automatic climate control.▷The interior is not yet heated or cooled as
much as desired.▷The engine is not yet at operating tempera‐
ture.▷Sharp steering angle or the steering wheel
is being turned.▷After driving in reverse.▷Fogging of the windows when the automatic
climate control is switched on.▷Vehicle battery charge is very low.▷Hood is unlocked.Seite 47DrivingControls47

Parking brake
The concept
Your vehicle is equipped with an electrome‐
chanical parking brake that can be set and re‐
leased by using a button.
The parking brake is primarily used to prevent
the vehicle from rolling when it is parked.
When the vehicle is stationary, the parking brake
acts on the rear wheels via an electromechanical
mechanism. When the vehicle is rolling or being
driven, the parking brake acts on the disc brakes
of the front and rear wheels via the hydraulic
brake system.
Setting
Pull the button. The parking brake is set. The indicator lamp in the instrument
cluster and the LED on the button light
up red. The parking brake is set.
Indicator lamp in Canadian models.
To set the parking brake, the remote control
does not need to be in the ignition lock.
While driving
If exceptional circumstances should make it
necessary to engage the parking brake while the
vehicle is in motion, pull the button for an ex‐
tended period: the vehicle brakes forcefully
while the button is being pulled.
The indicator lamp in the instrument
cluster lights up red, a sound is issued
and the brake lights light up.
Indicator lamp in Canadian models.
When the vehicle is braked almost to a halt, ap‐
prox. 2 mph/3 km/h, the parking brake remains
set.
Releasing Take the remote control with you
Take the remote control with you when
leaving the vehicle so that children, for example,
cannot start the engine or release the parking
brake.◀
The parking brake can only be released while the
ignition is switched on or the engine is running.
Manual transmission
Press the button of the parking brake. Depress
the brake and clutch pedals while doing so.
Sport automatic transmission
Press the parking brake button while the brake
is depressed or transmission position P is en‐
gaged.

Only add washer fluid when the engine is
cool, and then close the cover completely to
avoid contact between the washer fluid and hot
engine parts.
Otherwise, there is the danger of fire and a risk
to personal safety if the fluid is spilled.◀
All washer nozzles are supplied from one reser‐
voir.

antifreeze, according to the manufacturer's rec‐
ommendations.
