Overheating during slow driving in queues can
be avoided by driving in stages: Stop the car
and wait with your foot on the brake pedal until
there is a moderate distance to the traffic
ahead, drive forward a short distance, and then
wait another moment with your foot on the
brake pedal.IMPORTANT
Use the foot brake to hold the car stationary
on an uphill gradient - do not hold the car
with the accelerator pedal. The gearbox
could then overheat.
For important information regarding Powershift
transmission and towing - see page 289.
Text message and actionIn some situations the display may show a
message at the same time as a symbol is illu-
minated.

The table shows three steps with an increased
degree of seriousness should the transmission
become too hot. In parallel with the display text
the driver is also advised that the car's elec-
tronics are temporarily changing the driving
characteristics. Follow the instructions on the
information display where appropriate.NOTE
The table's examples are no indication that
the car is defective but instead show that a
safety function has been activated inten-
tionally to prevent damage to one of the
car's components.
WARNING
If a warning symbol combined with the textTransm. overheat park safely is ignored
then the heat in the gearbox may become
so high that the power transmission
between engine and gearbox is temporarily

NOTE
After starting with the key and each auto-
stop the car must first reach 5 km/h before
the automatic Start/Stop function is re-acti-
vated - following which certain conditions
must also be fulfilled, refer to these under
the heading "The engine does not auto-
stop".
All of the car's normal systems such as lighting,
radio, etc. work as normal even with an engine
that has stopped automatically, except that
some equipment may have the function tem-
porarily reduced, e.g. the climate control sys-
tem's fan speed or extremely high volume on
the audio system.
Auto-stopping the engineIn order that the engine should stop automati-
cally the car must be completely stationary:
ConditionsM/AA
Declutch, set the gear lever in
neutral position and release the
clutch pedal - the engine is
switched off.M
Stop the car with the foot brake
and then keep your foot on the
pedal - the engine stops automat-
ically.A
AM = Only manual gearbox, A = Only automatic gearbox and
model D3.
The AUTO START symbol on
the information display illumi-
nates as verification and
reminder that the engine is
has stopped automatically.
Auto-starting the engine
ConditionsM/AA
With the gear lever in neutral posi-
tion: Depress the clutch pedal -
the engine starts. Engage a suit-
able gear and continue the jour-
ney.M
With the gear lever in neutral posi-
tion: Depress the accelerator
pedal - the engine starts. Engage
a suitable gear and continue the
journey.M
The following option is also avail-
able on a downhill gradient:
Release the foot brake and let the
car move off - the engine starts
automatically when the speed
exceeds normal walking pace.M
Release the foot pressure on the
foot brake - the engine starts
automatically and the journey can
continue.A

Start assistance HSAThe foot brake can also be released on an uphill
gradient to start the engine automatically - the
HSA function means that the car does not roll
backwards.
HSA (Hill Start Assist) means that the pressure
in the brake system remains temporarily avail-
able while the driver moves his/her foot from
the brake pedal to the accelerator pedal for
driving off with the engine having stopped
automatically. The temporary braking effect
releases after a couple of seconds or when the
driver accelerates.
There is more information available on HSA on
page 120.
Gear indicator1
An essential detail in connection with environ-
mental driving is to drive in the right gear and
change gear in time.
The driver is assisted by an indicator which
notifies the driver when it is most advanta-
geous to engage the next higher or lower gear
- GSI (Gear Shift Indicator).
Indication is made with an up or down arrow in
the combined instrument panel's right-hand
display.
Deactivating the Start/Stop functionIn certain situations, it may
advisable to temporarily
switch off the automatic
Start/Stop function - this is
carried out by pressing this
button once, at which point
the button's lamp goes out.
Disengaged Start/Stop func-
tion is indicated by the infor-
mation display's symbol
going out and the message
Auto Start-Stop OFF being
displayed for
about 5 seconds - while the
button's lamp goes out at the
same time.
The Start/Stop function is disengaged until it is
reactivated with the button or until the next
time the engine is started with the key.
Limitations
The engine does not auto-stopEven if the Start/Stop function is activated, the
engine does not stop automatically if:
ConditionsM/AA
the driver has opened the seat-
belt's buckle.A
the car does not stop completely.
the capacity of the battery is
below the minimum permissible
level.
the engine does not have normal
operating temperature.
outside temperature is below
freezing point or above
approx. 30 °C.

The engine auto-starts without driver
intervention
An engine that has stopped automatically may
restart in some cases without the driver having
decided that the journey should continue. In
the following cases the engine also starts auto-
matically if the driver has not depressed the
clutch pedal (manual gearbox) or takes his/her
foot off the brake pedal (automatic gearbox):
