WARNING!
If your vehicle has been subjected to flood conditions (e.g. soaked car\
peting/standing water on the
floor of the vehicle) or if your vehicle has become flood-damaged in an\
y way, do not attempt to start
the vehicle or put the key in the ignition before disconnecting the batt\
ery (see below). This may cause
airbag deployment which could result in personal injury. Have the vehicl\
e towed to a trained and
qualified Volvo service technician for repairs.
Automatic transmission:
Before attempting to tow the vehicle, use the following procedure to ove\
rride the shiftlock system to
move the gear selector to the neutral position:
l Switch off the ignition for at least 10 minutes and disconnect the batte\
ry
l Wait at least one minute.
l Insert the key in the ignition and turn it to position II.
l Press firmly on the brake pedal.
l Move the gear selector from (P)ark to the (N)eutral position.

Front airbags
The front airbag system
The front airbags supplement the three-point seat belts. For these airba\
gs to provide the protection
intended, seat belts must be worn at all times.
The front airbag system includes gas generators (1) surrounded by the \
airbags (2) and a deceleration
sensor (3) that activates the gas generators, causing the airbags to b\
e inflated with nitrogen gas.
As the movement of the seats' occupants compresses the airbags, some of \
the gas is expelled at a

the difference in speed is immediately detected. This triggers the Anti-\
lock Brake System, which brakes
the spinning wheel until the difference in rotational speed is corrected\
.
TC is most active at low speeds, and a pulsating sound will be audible w\
hen the system is regulating
wheel spin. This is quite normal.
This is one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.
2. Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the vehicle is
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps
improve tractive force.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force. This is
done by pressing the DSTC button on the center control panel for at leas\
t a half a second.
When the SC function has been switched off:
l The text window will briefly display "DSTC SPIN CONTROL OFF"
l The LED in the DSTC button will be off.
3. Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cor\
nering, by braking one or more
of the wheels if the vehicle shows a tendency to skid or slide laterally\
. This is done by activating the
Anti-lock Braking System. A pulsating sound will be audible when the fun\
ction is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is also one of the DSTC system's permanent functions and is not aff\
ected when the DSTC button on
the center control panel is pressed.
4. Roll Stability Control (RSC)
RSC utilizes a gyro-sensor to monitor the vehicle's angle of inclination\
, and the rate at which this angle
changes. If necessary, RSC activates the Anti-lock Brake System to brake\
one or more of the wheels to
help maintain stability. A pulsating sound will be audible when the func\
tion is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.
The DSTC button
The DSTC button in the center control panel is used to switch the Spin C\
ontrol (SC) function on or off.
