automatically if AUTO is selected. The previously set blower speed is disconnected.
NOTE
If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air
conditioning are switched off. The display shows the blower symbol and OFF.
3. Recirculation
This function can be used to shut out exhaust fumes, smoke, etc from the passenger compartment. The air in the
passenger compartment is then recirculated, i.e. no air from outside the vehicle is taken into the vehicle when this
function is activated.
If the air in the vehicle recirculates for too long, there is a risk of condensation forming on the insides of the windows,
especially in winter.
Timer
The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected. See page 78
for information on setting the recirculation timer.
NOTE
Recirculation is always disengaged if the defroster button is engaged to clear ice or condensation from the side

windows.
4. Defroster
Directs airflow to the windshield and side windows and increases blower speed.
When the defroster is activated:
Air flows to the windows at high blower speed.
The LED in the defroster button lights up when this function is activated. The air conditioning system is controlled
to provide maximum air dehumidification.
The air conditioning is automatically switched on (can be switched off by pressing button 6).
The air is not recirculated.
5. Airflow controls
Press one of the three buttons in the illustration to activate the selected airflow. A symbol in the display above the
climate control panel and a lit LED in the selected button indicate that the manual function has been selected. With
manually selected airflow both warm and cool air can be selected. See also the table on page 95
.
6. Air conditioning On/Off
ON: The air conditioning system is engaged when the ON light is lit and is controlled automatically by the system to
maintain the selected temperature.

When the battery begins to lose its charge, the Information symbol in the instrument panel (see page 51) lights up and
REMOTE BATTERY LOW VOLTAGE is shown in the information display.
Replacing the battery in the remote control
If the range of the transmitter is noticeably reduced, this indicates that the battery (type CR 2450, 3V) is weak and
should be replaced. To replace the battery:
1. Place the remote control with the keypad downward. Pry open the cover with a small slotted screwdriver.
2. Remove the cover.
3. Note how the + and - sides of the battery are positioned on the inside of the cover (see the underside of the cover).

in the ignition switch.
NOTE
The number of doors that are unlocked at the same time can be set in the Personal settings menu. See page 78 for
additional information.
If one or more doors and/or the rear liftgate is not fully closed when the lock button is pressed, the door(s) or rear
liftgate will not be locked.
On keyless drive vehicles with an automatic transmission, the gear selector must be in the Park ( P) position and
the ignition must be switched off before the doors/trunk can be locked.
Keyless drive remote control and driver's seat memory
This function is only available on vehicles equipped with the optional power driver's seat.
When you leave the vehicle with a keyless drive remote control in your possession and lock any door, the position
of the driver's seat will be stored in the seat's memory.
The next time a door is opened by a person with the same remote control in his/her possession, the driver's seat will
automatically move to the position that it was in when the door was most recently locked.
NOTE
If several people carrying keyless drive remote controls approach the vehicle at the same time, the driver's seat will
assume the position it was in for the person who opens a door first.
Keyless drive information messages
If anyone leaves the vehicle with the only keyless drive remote control in his or her possession while the ignition is
switched on,
124 05 Locks and alarm

a message will be shown in the information display and an audible signal will sound.
NOTE
This message will only be displayed if the start control is in position I or II.
The message will be erased from the display and the audible signal will stop when the remote control has been
returned to the vehicle and one of the following has occurred:
A door has been opened and closed
The start control has been turned to position 0
The READ button (see page 56 for the location of this button) has been pressed.

The battery is disconnected (while the alarm is armed).
The siren is disconnected when the alarm is disarmed.

driving, requiring the frequent use of the washers and wipers. Volvo Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water Down to 5° F (-15° C): 1 part washer solvent and 3
parts water Down to 0° F (-18° C): 1 part washer solvent and 2 parts water Down to -18° F (-28° C): 1 part washer
solvent and 1 part water.
Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de -icing sprays as they can cause damage to the locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio
system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This
position reduces drain on the battery.
Please keep in mind that using systems, accessories, etc that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the cargo area provides electrical current even with the ignition switched off, which
drains the battery.
NOTE
If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel
when the battery charge is low.
An energy conserving function designed into the vehicle's electrical system will switch off certain functions or
reduce the load on the battery by, e.g., reducing the audio system's volume.

General information
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. An authorized Volvo retailer will also be able to supply you with bulbs, fuses, spark plugs and
wiper blades for your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that the engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage.
Have the transmission oil level checked1.
Check condition of drive belts.
Check state of the battery's charge.
Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures.
The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service
technician only.
Check all lights, including high beams.
Reflective warning triangles are legally required in some states/provinces.
Have a word with a trained and qualified Volvo service technician if you intend to drive in countries where it may

Turn the key to this position and release it immediately. The key returns automatically to the Drive position.
A chime will sound if the key is left in the ignition and the driver's door is opened (does not apply to vehicles with the
optional keyless drive).
Steering wheel lock
When the key is removed from the ignition, the steering wheel locks so that it cannot be turned.
NOTE
The steering wheel lock is activated when the driver's door is opened on vehicles with the optional keyless drive.
Releasing the steering wheel lock
If the front wheels are hard up against a curb, the steering wheel lock may be under too much tension to unlock.
If so, the key will turn in the ignition switch but the vehicle will not start.
At the same time, a message "Steering locked turn wheel" will appear in the information display.
If this happens:
1. Remove the key
3 from the ignition.
2. Turn the steering wheel slightly and hold it to release pressure on the lock mechanism.
3. Reinsert the key and start the vehicle.
The steering should immediately unlock. If not, try again.
NOTE
In order to help reduce vehicle theft, make sure the steering wheel lock is engaged before leaving the vehicle.
3 Vehicles with optional keyless drive: Turn the start control to position 0, turn the wheel slightly to release the pressure, and turn the start control
to position III to start the vehicle.
140 06 Starting and driving
Ignition switch/Steering wheel lock
WARNING
Never switch off the ignition (turn the ignition key or start control to position 0) or remove the key or start control
from the ignition switch while the vehicle is in motion. This could cause the steering wheel to lock, which would
make the vehicle impossible to steer.

be longer.
A warning light in the instrument panel will light up to warn the driver that a fault has occurred.
If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush, etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that if
you are towing a trailer, the brakes will be subjected to a greater than normal load.
Anti-lock brakes (ABS)
The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking
conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically
modulated in order to help prevent lockup that could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed
of approximately 12 m.p.h. (20 km/h) . The brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
