seated occupant and determine if the passeng-er's side front airbag should be enabled (mayinflate) or disabled (will not inflate).
The OWS will disable (will not inflate) the pas-senger's side front airbag when:
•the front passenger's seat is unoccupied, orhas small/medium objects in the front seat,
•the system determines that an infant is pres-ent in a rear-facing infant seat that is instal-led according to the manufacturer's instruc-tions,
•the system determines that a small child ispresent in a forward-facing child restraintthat is installed according to the manufactur-er's instructions,
•the system determines that a small child ispresent in a booster seat,
•a front passenger takes his/her weight off ofthe seat for a period of time,
•a child or a small person occupies the frontpassenger's seat.
The OWS uses a PASSENGER AIRBAG OFFindicator lamp which will illuminate and stay on toremind you that the passenger's side front airbagis disabled. The PASSENGER AIRBAG OFF indi-cator lamp is located in the overhead console,near the base of the rearview mirror.

NOTE
When the ignition is switched on, the OWSindicator light will illuminate for several sec-onds while the system performs a self-diag-nostic test.
However, if a fault is detected in the system:
•The OWS indicator light will stay on
•The SRS warning light will come on and stayon and a text message will be displayed.

WARNING
If a fault in the system is detected and indi-cated as described, be aware that the pas-senger's side front airbag will not deploy inthe event of a collision. In this case, the SRSsystem and Occupant Weight Sensor shouldbe inspected by a trained and qualified Volvoservice technician as soon as possible.
WARNING
•Never try to open, remove or repair anycomponents in the OWS system. Thiscould cause the system to malfunction.Maintenance or repairs should only becarried out by an a trained and qualifiedVolvo service technician.
•The front passenger's seat should not bemodified in any way. This could reducepressure on the seat cushion, whichmight interfere with the OWS system'sfunction.

The climate in the passenger compartment can
be maintained when the vehicle is parked, e.g. if
the engine is turned off but the driver or passen-
gers remain in the vehicle. This function can only be direct-started.
The function utilizes several of the vehicle's sys-
tems:
• Residual heat from the engine is used to
help heat the passenger compartment to a
comfortable temperature.
• In warm weather, the ventilation system cools
the passenger compartment by blowing air in
from outside.
NOTE Climate comfort maintenance will be deacti-
vated if the vehicle is locked from the outside
in order to avoid using residual engine heat
unnecessarily. This function is intended to be
used to maintain climate comfort when the
driver or a passenger remains in the vehicle
after the engine is turned off.

DRIVER SUPPORT
}}
* Option/accessory. 295
WARNING•
The radar sensor has a limited field of
vision. In some situations, it may detect a
vehicle later than expected or not detect
other vehicles at all.
• The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.
• The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.
• Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.
• Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see. Poor
weather or winding roads can affect the
radar sensor's capacity to detect vehicles
ahead.
• A vehicle's size (e.g., a motorcycle) can
also affect the radar sensor's capacity to
detect another vehicle. This may result in
the warning light illuminating at a shorter
distance than the one that has been set
or not illuminating at all. •
High speeds may also result in the warn-
ing light illuminating at a shorter distance
than the one that has been set due to
limitations in the radar sensor's range.
NOTE The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

Distance Alert* (p. 291) Adaptive Cruise Control*
Adaptive Cruise Control (ACC 41
) helps the
driver maintain a constant speed with a set time
interval to the vehicle ahead.
Adaptive Cruise Control helps provide a more
relaxed driving experience on long trips on high-
ways or long, straight roads with even traffic
flows. The camera/radar sensor measures the distance to the
vehicle ahead
42
.
The driver sets a speed and a time interval to the
vehicle ahead. If the camera/radar sensor detects
a slower-moving vehicle ahead, your vehicle's
speed will be automatically adapted according to
the set time interval to that vehicle. When there
are no longer slower-moving vehicles ahead, the
vehicle will return to the set speed.
