Technician certification
In addition to Volvo factory training, Volvo sup- ports certification by the National Institute forAutomotive Service Excellence (A.S.E.).
Certified technicians have demonstrated a high degree of competence in specific areas. Besidespassing exams, each technician must also haveworked in the field for two or more years before acertificate is issued. These professional techni-cians are best able to analyze vehicle problemsand perform the necessary maintenance proce-dures to keep your Volvo at peak operating con-dition.
Twin Engine vehicles
Technicians performing work on a vehicle with electrification should also have the necessary training and specialized certification required for performing repairs and/or maintenance on avehicle with electrification.
WARNING
A number of electrical components in Twin Engine vehicles use high-voltage current andcan be extremely dangerous if handled incor-rectly. These components and any orange wir-ing in the vehicle may only be handled bytrained and qualified Volvo service techni-cians.

Seat belts
Seat belts should always be worn by all occu- pants in your vehicle. Children should be prop-erly restrained using an infant seat, adjustablechild seat or booster cushion as determined byage, weight and height.
Most states and provinces make it mandatory for occupants of a vehicle to use seat belts.
Seat belt maintenanceCheck periodically that the seat belts are in goodcondition. Use water and a mild detergent forcleaning. Check the seat belt mechanism's func-tion as follows: attach the seat belt and pull rap-idly on the strap.

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 OWS indicator 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 stay on 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 any components 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.

Climate comfort retaining function
The climate in the passenger compartment can be maintained when the vehicle is parked, e.g. ifthe 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 tohelp heat the passenger compartment to acomfortable temperature.
• In warm weather, the ventilation system coolsthe passenger compartment by blowing air infrom outside.
NOTE
Climate comfort maintenance will be deacti- vated if the vehicle is locked from the outsidein order to avoid using residual engine heatunnecessarily. This function is intended to beused to maintain climate comfort when thedriver or a passenger remains in the vehicleafter 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 avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn- ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

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 trafficflows.
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 thereare no longer slower-moving vehicles ahead, thevehicle will return to the set speed.
