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.

Passenger compartment air filter
All air entering the passenger compartment through the climate control system intake is fil-tered.
Replacing the passenger compartment filter
To maintain the high performance of the climate control system, the filter must be replaced regu-larly. Follow Volvo's service schedule for recom-mended replacement intervals. When driving inareas with a lot of smog, dust, etc., the filter mayneed to be changed more frequently.
NOTE
There are two types of passenger compart- ment filters. Make sure that the correct filteris installed.

Foot movement tailgate operation *
To make it easier to operate the tailgate 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 18
.
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 be heard when opening or closing is activated - the tail- gate will open/close. If the tailgate 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. Do not keep your foot under the vehicle in a kick-ing motion. This may prevent activation.
Interrupting opening or closing with a foot
movement
–Make
one slow forward kicking motion while
the tailgate is opening or closing to stop its movement.
The remote key does not need to be within rangeof the vehicle to interrupt opening or closing.
NOTE
There is a risk of reduced or lost function if there are large amounts of snow, ice, dirt, etc.on the rear bumper. Make sure to keep thebumper clean.
NOTE
Please note that the system could be inadver- tently activated in a car wash or similar if theremote key is within range.

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.

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.
