Functions
A/C – ON/OFF
•The air conditioning functions only at temperatures above 32°F (0°C).
• While the Defroster function is selected,the air conditioning is temporarily acti-vated to dehumidify the air, even if youhave manually switched the air condition- ing off. This will only function if the bloweris not switched off.
Press the switch to turn the air conditioning on or off. The " ON" or " OFF" LED will light up
to indicate if the system is switched on or off.Other functions will still be regulated auto-matically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter and air quality sensor. The filter separatesgases and particles, thereby reducing theamounts of odors and contaminants enteringthe vehicle. The air quality sensor detectsincreased levels of contaminants in the out-side air. When the air quality sensor detects

contaminated outside air, the air intake closes and the air inside the passenger compart-ment is recirculated, i.e. no outside air entersthe vehicle. The filter also cleans recirculatedpassenger compartment air. When the ECC system is in the
AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation function (air in the passenger compartmentrecirculates – no fresh air enters the compart-ment). The LED in the switch will light up toindicate that the function is engaged. • Use this function if the outside air is con- taminated with exhaust gases, smoke,etc or to heat/cool the vehicle quickly.
• Recirculation should not be used for morethan 15 minutes. If your windows begin tofog or mist, make sure that the recircula-tion function is switched off.
• Selecting
Defroster automatically
switches recirculation off.
• Timer mode activation: (Vehicles equip-ped with the Interior Air Quality systemhave no timer mode) Press and hold therecirculation button for at least 3 secondsto activate a recirculation timer mode.The amber LED in the recirculation buttonwill flash 5 times to show that the timermode is being activated. In timer mode, each time the recirculation button ispressed, the climate control system willrecirculate the air in the passenger com-partment for 5 – 12 minutes, dependingon the outside air temperature, and thenrevert back to fresh air.
• Timer mode deactivation: Press and holdthe recirculation button for 3 seconds.The amber LED in the recirculation buttonwill illuminate steadily for 5 seconds toshow a return to "normal" mode.
• In normal mode, when the recirculationbutton is pressed, the climate controlsystem will recirculate the air in the pas-senger compartment until the recircula-tion button is pressed again.
• Timer mode memory: If the vehicle isturned off while timer mode is active,timer mode will still be active when thevehicle is restarted.
AUTO
This function automatically regulates the Electronic Climate Control system so that theselected temperatures are maintained. Theblower, heating, air distribution (air flow), airconditioning, and optional air quality sensorare controlled. If you prefer to manually setany of these functions, the remaining func-tions will still be controlled automatically.Pressing the
AUTO button overrides any set-
tings that were previously made manually.

WARNING
Never use the transmitter to lock the doors from inside the vehicle.• Doing so would ACTIVATE:
• the break-in alarm, which would sound if one of the doors were opened
• the optional interior motion and incli-nation alarm sensors.
• Doing so would DEACTIVATE:
• the moonroof and interior courtesylight controls.
• the central locking buttons on the frontdoor armrests, although the interiordoor handles would still function toallow occupants to leave the vehicle.
• Disabled features would remain disa-bled until the remote is used again tounlock the vehicle.
• In addition, locking an occupied vehi-cle would hinder rapid access to theoccupants in an accident or emer-gency.
Replacing the battery in the remote keyIf the range of the transmitter is noticeably reduced, this indicates that the battery isweak and should be replaced.
To replace the battery:1. Carefully pry open the rear edge of the
cover with a small screwdriver.
2. Insert a new 3-volt, CR2032 battery, with the battery's plus side up. Avoid touching the contact surfaces of the battery withyour fingers.
3. Press the cover back into place. Ensure that the rubber seal is correctly posi-tioned to help keep out moisture.
NOTE
The old battery should be disposed of properly at a recycling center or at yourVolvo retailer.

* Option/accessory, for more information, see Introduction.133
The alarm is automatically armed whenever you lock your vehicle. When armed, the alarm continuously moni- tors a number of points on the vehicle. Thefollowing conditions will set off the alarm: •
The hood is forced open.
• The tailgate is forced open.
• A door is forced open.
• The ignition switch is tampered with.
• If there is movement in the passenger compartment (if the vehicle is equippedwith the optional movement sensor).
• The vehicle is lifted or towed (if the vehi-cle is equipped with the optional inclina-tion sensor).
• The battery is disconnected (while thealarm is armed).
• The siren is disconnected when the alarmis disarmed.
Arming the alarm1. Press the
LOCK button on the remote
key.
2. Lock the vehicle using the key blade in the driver's door or press the central lock button on the driver's door with the dooropen.
One long flash of the turn signals will confirmthat the alarm is armed.
Movement sensor*In addition to triggering the alarm if there ismovement in the passenger compartment,currents of air may also affect the movementsensor. This means that locking the vehiclewith the windows or the moonroof open, orusing an accessory portable passenger com-partment heater, could trigger the alarm. To help avoid this, close the windows and moonroof before locking the vehicle. If a pas-senger compartment heater is used when thevehicle is locked, direct airflow from the heat-er's vent(s) so that it isn't directed upward inthe passenger compartment.
Disarming the alarmPress the UNLOCK button on the remote key
or unlock the doors with the key blade.
Turning off (stopping) the alarmIf the alarm is sounding, it can be stopped bypressing the UNLOCK button on the remote
key or by unlocking the driver's door with thekey blade.
Visual alarm signalThe visual alarm signal is given by flashing allturn signals and turning on the interior lightingfor approximately 5 minutes.
Audible alarm signalAn audible alarm signal is given by a batterypowered siren. One alarm cycle lasts for25 seconds.
"Panic" buttonIn an emergency situation, this feature can beused to attract attention. Activate the "panic" button by pressing the red button on the remote key ( see page 127for illustration) for at least 3 seconds or bypressing this button twice within 3 seconds.The turn signals will flash, and the vehicle'shorn will sound. The function can be turned off by pressing any of the buttons on the remote key or willstop automatically after 25 seconds. When abutton is pressed, there is a 5 second delaybefore the panic alarm is deactivated.
NOTE
This button will NOT unlock the vehicle.

Engine oil
Although some oil consumption occurs dur- ing normal engine operation, more oil is con-sumed when the engine is new as the internalparts generate higher friction while wearing-into each other. From the time the engine isnew until the first maintenance is performed,the oil consumption could be higher than nor-mal. For this reason, it is especially importantto check the oil regularly during this period,see page 222.
Fuel requirements
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gas- oline to control engine deposits. Detergentgasoline is effective in keeping injectors andintake valves clean. Consistent use of depositcontrol gasolines will help ensure good driva-bility and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station oper-ator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline be label-led "UNLEADED". Only these pumps havenozzles which fit your vehicle's filler inlet. It isunlawful to dispense leaded fuel into a vehiclelabelled "unleaded gasoline only". Leadedgasoline damages the three-way catalyticconverter and the heated oxygen sensor sys-tem. Repeated use of leaded gasoline willlessen the effectiveness of the emission con-trol system and could result in loss of emis-sion warranty coverage. State and local vehi-cle inspection programs will make detectionof misfueling easier, possibly resulting inemission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines con- tain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator lamp)located on your instrument panel maylight. If this occurs, please return yourvehicle to a trained and qualified Volvoservice technician for maintenance.
Gasoline containing alcohol and ethers"Oxygenated fuels" Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxy- genated" fuels; however, the octane ratingslisted on page 139 must still be met. Alcohol – Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanolmay also be referred to as Ethyl alcohol, or"Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.

160* Option/accessory, for more information, see Introduction.
Front/rear park assist
The park assist system is designed to assist you when driving into parking spaces,garages, etc. It utilizes four ultrasound sen-sors located in one or both bumpers to meas-ure the distance to a vehicle, object, or a per-son who may be close to the front or rear ofyour vehicle. Park assist is available in two versions:
• Rear bumper only
• Front and rear bumpers
WARNING
Park Assist is an information system, NOT a safety system. This system is designedto be a supplementary aid when parkingthe vehicle. It is not, however, intended toreplace the driver's attention and judge-ment.
Function
The system is activated automatically when the vehicle is started. The indicator light in thebutton in the center console illuminates. • The front park assist system is active from the time the engine is started untilthe vehicle exceeds a speed of approxi-mately 10 mph (15 km/h). It is also activewhen the vehicle is backing up.
• Rear park assist is active when the engineis running and reverse gear has beenselected.
Rear park assistThe distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comesfrom the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.
NOTE
Rear park assist is deactivated automati- cally when towing a trailer if Volvo genuinetrailer wiring is used.
Front park assistThe distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audiblesignal comes from the audio system's frontspeakers.
• It may not be possible to combine auxili- ary headlights and front park assist sincethese lights could trigger the system'ssensors.
Activating/deactivating park assist
The system is activated automatically when the vehicle is started.
• Press the Park assist button on the center console (see page 65) to temporarilydeactivate the system(s). The indicatorlight in the button will go out when thesystem has been deactivated.
• Park assist will be automatically reactiva-ted the next time the engine is started, orif the button is pressed (the indicator lightin the button will illuminate).

* Option/accessory, for more information, see Introduction.161
NOTE
• Front park assist is disengaged auto- matically when the parking brake isapplied.
• If the vehicle is equipped with frontand rear park assist, both systems willbe deactivated by pressing the button.
Audible signals from the park assist system
The Park Assist system uses an intermittent tone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. If thevolume of another source from the audio sys-tem is high, this will be automatically lowered. If there are objects within this distance both behind and in front of the vehicle, the signalalternates between front and rear speakers.
Faults in the system
If the yellow warning symbol illu- minates and PARK ASSIST
SERVICE REQUIRED is shown
on the information display, this indicates that the system is not
functioning properly and has been disen-gaged. Consult a trained and qualified Volvoservice technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.
Cleaning the sensors
G026946
Park assist sensors The sensors must be cleaned regularly to ensure that they work properly. Clean themwith water and a suitable car washing deter-gent. Ice and snow covering the sensors may cause incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt, snow, or ice, this could result in falsewarning signals from the park assist sys-tem.
