Quieter and cleaner
Environmental care is one of Volvo Car Corpo-
ration's core values and it influences all of our
operations. This target-orientation has resulted
in the DRIVe vehicle series whose concept
consists of an interaction between several sep-
arate energy-saving functions, all with the
common purpose of reducing fuel consump-
tion, which in turn contributes to reduced
exhaust emissions.
General information on Start/Stop
The engine is switched off - it becomes quieter and
cleaner....
Some combinations of engine and gearbox are
equipped with a Start and Stop function which
engages in the event of e.g. stationary traffic or
waiting at traffic lights - the engine is then
switched off temporarily and restarts automat-
ically when the journey is due to continue.
The Start/Stop function gives the driver the
opportunity for a more active environmentally
conscious way of driving the car by means of
being able to allow the engine to stop auto-
matically, whenever appropriate.
Manual or AutomaticNote that there are differences in the
Start/Stop function depending on whether the
gearbox is manual or automatic.
Function and operation

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.
