Night position
To reduce glare from the headlights of following vehicles, use control (1) to switch between the normal and night-driving
positions.
2. Normal position
3. Night position, reduces glare from following traffic
Auto-dim function (option)
An optional integrated sensor reacts to headlights from following traffic and automatically reduces glare.
Rearview mirror with compass (option)
The upper right-hand corner of the rearview mirror has an integrated display that shows the compass direction toward
which the vehicle is pointing. Eight different directions can be displayed: N, NE, E, SE, S, SW, W and NW. The display
shows your car's orientation with respect to true north.
Calibrating the compass

The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your vehicle contains a CFC-free refrigerant -
R134a. This substance will not deplete the ozone layer. The system contains 1.2 lbs (530 g) R134a (HFC 134a), and
uses PAG oil.
Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult a trained and qualified Volvo service technician for these intervals. The filter
should be replaced more often when driving under dirty and dusty conditions. The filter cannot be cleaned and
therefore should always be replaced with a new one.
NOTE
There are different types of cabin air filters. Ensure that the correct type is installed.
Display
The display above the climate control panel shows the climate settings that have been made.
Personal settings
There are two functions in the climate system that can be set to your preferences:
Blower speed to Auto mode (models with ECC only).
Timer controlled recirculation of the air in the passenger compartment.
For information about how to make these settings, see the Personal settings section on page 78
.

Sensors
The sunlight sensor is on the upper side of the dashboard
The passenger compartment temperature sensor is located behind the climate system control panel.
The ambient temperature sensor is in the driver's side door mirror.
The humidity sensor is in the rearview mirror.
These sensors should never be obstructed.

NOTE
The sunlight sensor monitors the side of the vehicle from which the sun shines into the passenger compartment. This
means that the temperature may differ slightly between the left and right air vents, even if the climate system
temperature is set to be the same for both sides of the passenger compartment.
Side windows and optional moonroof
The electronic climate control system will function best if the windows and moonroof are closed. If you drive with the
windows or moonroof open, it may be preferable to manually adjust the temperature and blower control (the LED in
the AUTO switch should be off).
Acceleration
The air conditioning system is temporarily switched off during full throttle acceleration.

When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good drivability and fuel
economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station
operator.
NOTE
Volvo does not recommend the use of store -bought fuel injector cleaning additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED." Only these pumps have nozzles which fit
your vehicle's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only."
Leaded gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness of the emission control

system and could result in loss of emission warranty coverage. State and local vehicle inspection programs will make
detection of misfueling easier, possibly resulting in emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl- cyclopentadienyl manganese
tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected, and the
Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel. Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must
still be met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as
Ethyl alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE may be used.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your vehicle, lead has been strongly linked to certain forms of cancer. Many fuels

Park assist (Option/accessory)
Introduction
The park assist system is designed to assist you when driving into parking spaces, garages, etc. It utilizes four
ultrasound sensors located in one or both bumpers to measure the distance to a vehicle, object, or a person who may
be close to the front or rear of your 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 designed to be a supplementary aid when
parking the vehicle. It is not, however, intended to replace the driver's attention and judgement.
Function

The system is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates.
The front park assist system is active from the time the engine is started until the vehicle exceeds a speed of
approximately 10 mph (15 km/h). It is also active when the vehicle is backing up.
Rear park assist is active when the engine is running and reverse gear has been selected.
Rear park assist
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comes from the rear speakers.
The system must be deactivated when towing a trailer, carrying bicycles in a rear-mounted carrier, etc, which could
trigger the rear park assist system's sensors.
NOTE
Rear park assist is deactivated automatically when towing a trailer if Volvo genuine trailer wiring is used.
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.
161 06 Starting and driving
Park assist (Option/accessory)
Activating/deactivating park assist
The system is activated automatically when the vehicle is started.
If the vehicle is equipped with both front and rear park assist , press the park assist button on the center console
(see the illustration) to temporarily turn off (deactivate) the systems. The indicator light in the button will go out when
the system has been switched off.
If the vehicle is equipped with rear park assist only, a message will be displayed when reverse gear is selected
showing if the system is on or off. Press EXIT to turn rear park assist off, or ENTER to turn the system on.
Park assist will be automatically reactivated the next time the engine is started, or if the button is pressed (the
indicator light in the button will illuminate).

NOTE
Front park assist is disengaged automatically when the parking brake is applied.
If the vehicle is equipped with front and rear park assist, both systems will be 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 to an object, and becomes
constant when you are within approximately 1 ft (30 cm) of an object in front of or behind the vehicle. If the volume
of another source from the audio system is high, this will be automatically lowered.
If there are objects within this distance both behind and in front of the vehicle, the signal alternates between front and
rear speakers.
Faults in the system
If the information symbol illuminates and PARK ASSIST SERVICE REQUIRED is shown on the information display,
this indicates that the system is not functioning properly and has been disengaged. Consult a trained and qualified
Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.
162 06 Starting and driving
Park assist (Option/accessory)
Cleaning the sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with water and a suitable car
washing detergent.

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 false warning signals from the park assist
system.
