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 engine and gearbox combinations come
fitted 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/Stop On/Off.
Illuminates briefly on activation and for text
messages.
The engine is auto-stopped.
The Start/Stop function is activated
automatically when the engine is
started with the key. The driver is alerted to the
function by means of this symbol on the instru-
ment panel illuminating briefly, the display text
Auto Start-Stop ON is shown and the green
lamp for the On/Off button illuminates.
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 engineThe following is required for the engine to auto-
stop:
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 = Manual gearbox, A = Automatic gearbox.
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 or
press 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
AM = Manual gearbox, A = Automatic gearbox.
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 fordriving 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 125.
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.

All-wheel drive – AWD*

134* Option/accessory, for more information, see Introduction.
All Wheel Drive is always available
All Wheel Drive means that the car is driving all
four wheels at the same time.
The power is automatically distributed
between the front and rear wheels. An elec-
tronically controlled clutch system distributes
the power to the wheels that have the best grip
on the current road surface. This provides the
best traction and prevents wheel spin. Under
normal driving conditions, the majority of
power is transmitted to the front wheels.
All Wheel Drive improves driving safety in rain,
snow and icy conditions.
