Climate control sensors
The climate system has a number of sensors to help regulate the climate settings in the vehicle.
Location of the sensors
Humidity sensor - in the rearview mirror con- sole.
Ambient temperature sensor - in the right- side door mirror.
Sunlight sensors - on the upper side of the dashboard.
Passenger compartment temperature sensor - near the buttons in the center console.
NOTE
Do not cover or block the sensors with cloth- ing or other objects.
On vehicles equipped with the Interior Air Quality System *, there is also an air quality sensor in the
climate system's air intake.

Perceived temperature
The climate control system regulates the climate in the passenger compartment based on per-ceived temperature, not actual temperature.
The selected passenger compartment tempera- ture is based on the physical perception of thecurrent ambient temperature, airflow speed,humidity, sunlight in the passenger compartment,etc. The system has a sunlight sensor that detects which side of the vehicle the sunlight is shiningon and adjusts the temperature accordingly. Thismeans that the temperature of the air coming outof the vents may be different for the left and rightsides, even if the temperature setting is the samefor both sides.

Clean Zone Interior Package *
Clean Zone Interior Package (CZIP) is a series of modifications that filters even more allergy andasthma-inducing substances from the passengercompartment.
CZIP includes the following:
• An enhanced function that starts the blower when the vehicle is unlocked using theremote key. The blower will then fill the pas-senger compartment with fresh air. The func-tion starts when required and switches offautomatically after a period of time or whenone of the passenger compartment doors isopened. The amount of time the blower runsgradually decreases due to reduced need upuntil the vehicle is 4 years old.
• The fully automatic Interior Air QualitySystem (IAQS).

Interior Air Quality System
*
Interior Air Quality System (IAQS) is a fully auto- matic air quality system that removes gases andparticles to reduce odors and contaminants inthe passenger compartment.
IAQS is part of the Clean Zone Interior Package (CZIP) and removes air contaminants such asparticles, hydrocarbons, nitric oxides and ground-level ozone. If the system's air quality sensors detect contami- nants in the outside air, the air intake closes andair recirculation is activated.
NOTE
To ensure optimal air quality in the passenger compartment, the air quality sensor shouldalways be engaged. Recirculation is limited in cold weather to pre- vent fogging. In the event of fogging, use the defroster functions for the windshield, side windowsand rear window.

Opening and closing the trunk lid
with foot movement
*
To make it easier to operate the trunk lid when your hands are full, it can be opened and closedby moving your foot in a forward kicking motionunder the rear bumper.
The sensor is located to the left of center under the rear bumper.
One of the vehicle's remote keys must be within range behind the vehicle (approx. 1 meter (3feet)) for opening and closing to be possible. Thisapplies even if the vehicle is unlocked in order toprevent the trunk lid from inadvertently openinge.g. at a car wash.
Foot movement operation
Kicking motion within the sensor's activation area.
–Make one slow forward kicking motion with
your foot under the left section of the rear bumper. Take a step back. Do not touch thebumper.
> A brief audible signal will sound when opening or closing is activated - the trunk lid will open/close. If the trunk lid is open, it will always close 19
when the foot motion sensor is
activated.
If several opening attempts have been made without the remote key in range behind the vehi-cle, foot movement operation will not be availablefor a short period of time.
19 Applies to vehicles with power trunk lid *.

DRIVER SUPPORT
* Option/accessory.
262
Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

Speed-dependent steering wheelresistance
Speed-dependent power steering increases the steering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. When parking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering may become too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

NOTE
•The greater the vehicles' speed, the greater the distance between them for aset time interval.
• Only use the time intervals permitted bylocal traffic regulations.
• The set time interval is also used by theAdaptive Cruise Control and Pilot Assistfunctions.
WARNING
•Only use a time interval suitable for the current traffic conditions.
• The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Distance Alert limitations36
Distance Alert functionality may be reduced in certain situations.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 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 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 37
) 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 38
.
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, thevehicle will return to the set speed.
WARNING
•
The Adaptive Cruise Control function is supplementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Adaptive Cruise Control is not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
Depending on market, this function may be either Standard or Optional.

Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts to regu- late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, when there are great differences inspeed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
• Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
• Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com- ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
