NOTE
Some devices may require you to replace
this Programming Step 2 with procedures
noted in the “Gate Operator / Canadian Pro-
gramming” section. If the HomeLink indica-
tor light does not change to a rapidly blink-
ing light after performing these steps, con-
tact HomeLink at www.homelink.com.
3.
Firmly press, hold for five seconds and
release the programmed HomeLink but-
ton up to two separate times to activate the
door. If the door does not activate, press
and hold the just-trained HomeLink button
and observe the indicator light.
•If the indicator light stays on con-
stantly, programming is complete
and your device should activate when
the HomeLink button is pressed and
released.
•If the indicator light blinks rapidly for
two seconds and then turns to a con-
stant light continue with “Program-
ming” steps 4-6 to complete the pro-
gramming of a rolling code equipped
device (most commonly a garage door
opener).
4. At the garage door opener receiver (motor-
head unit) in the garage, locate the “learn”
or “smart” button. This can usually befound where the hanging antenna wire is
attached to the motor-head unit.
5. Firmly press and release the “learn” or
“smart” button. (The name and color of the
button may vary by manufacturer.) There
are 30 seconds to initiate step 6.
6. Return to the vehicle and firmly press, hold
for two seconds and release the pro-
grammed HomeLink button. Repeat the
“press/hold/release” sequence a second
time, and, depending on the brand of the
garage door opener (or other rolling code
equipped device), repeat this sequence a
third time to complete the programming
process.
HomeLink should now activate your rolling
code equipped device.
Gate Operator/Canadian ProgrammingCanadian radio-frequency laws require trans-
mitter signals to “time-out” (or quit) after sev-
eral seconds of transmission – which may not
be long enough for HomeLink to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to “time-out” in the same manner.
If you live in Canada or you are having difficul-
ties programming a gate operator or garage
door opener by using the “Programming” pro-cedures, replace “Programming HomeLink”
step 2 with the following:
•Continue to press and hold the HomeLink
button while you press and release -
every two seconds (“cycle”) your hand-
held transmitter until the HomeLink indica-
tor light changes from a slow to a rapidly
blinking light. Now you may release both
the HomeLink and hand-held transmitter
buttons.
Proceed with “Programming” step 3 to com-
plete.
Using HomeLink
To operate, simply press and release the pro-
grammed HomeLink button. Activation will
now occur for the trained device (i.e., garage
door opener, gate operator, security system,
entry door lock, home/office lighting, etc.). For
convenience, the hand-held transmitter of the
device may also be used at any time. In the
event that there are still programming difficul-
ties or questions, contact HomeLink at:
www.homelink.com.

G030244
Controls for ventilated front seats
The ventilation system consists of fans in the
seats and backrests that draw air through the
seat upholstery. The cooling effect increases
as the air in the passenger compartment
becomes cooler.
The level of ventilation is adjusted on the con-
trol panel on the side of the seat. The fans can
be set to three speeds.
To start seat ventilation:

Press briefly on
.To gradually increase ventilation:

Press briefly on
.
For maximum ventilation:

Hold down
for approximately 2 sec-
onds.
To gradually decrease ventilation:

Press briefly on
.
To switch off ventilation:

Hold down
for approximately 2 sec-
onds.
The ventilation can be used at the same time
as seat heating*, for example, to help dry damp
clothing.
NOTE
•Seat ventilation cannot be started if the
temperature in the passenger compart-
ment is below 41°F (5°C).
•Seat ventilation should be used with
caution by people who are sensitive to
drafts. A moderate ventilation level
should be set if the function is used for
extended periods.

will light up to indicate that the defrost function
is engaged.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
•Recirculation will not function while defrost
is engaged.
The climate system will return to its previous
settings when the defroster function is
switched off.
Rear window and door mirror
defrosters
This function defrosts/deices the rear window
and door mirrors. The LED in the switch will
light up to indicate that the heating function is
engaged. For additional information on this
function see page 70.
Never use ice scrapers made of metal as they
can easily scratch the mirror surface.
Heated front seats*
1. Press the switch once for maximum seat
heating. Both LEDs in the switch will be lit.
2. Press the switch a second time for comfort
heating. One LED in the switch will be lit.3. Press the switch a third time to turn the

folded to a horizontal position to make room for
a long load. Fold the backrest as follows:1. Move the seat as far back as possible.
2. Adjust the backrest to the upright position.
3. Lift the catches on the rear of the backrest.
4. Without releasing the catches, push the
backrest forward.
5. Move the seat as far forward as possible
so that the head restraint slides under the
glove compartment.
WARNING
Cover sharp edges on the load to help pre-
vent injury to occupants. Secure the load to
help prevent shifting during sudden stops.
Power seat*

Programming the memoryThree different seating and door mirror posi-
tions can be stored in the driver seat's memory.
The following example explains how button 1
can be programmed. Buttons 2 and 3 can be
programmed in the same way.
To program (store) a seat position in button 1:
1. Move the seat to the desired position using
the seat adjustment controls (see
page 100).
2.
Press and hold down the MEM (memory)
button.3.
With the MEM button depressed, press
button 1 briefly to store the seat's current
position.
To move the seat to the position that it was in

G027068
The refrigerator is located under the cover in
the front seat center armrest. Use the button
(see the inset illustration) to adjust the level of
cooling.

Securing cargo

114
G027031
As a safety precaution, all cargo in your vehicle
should be securely anchored to keep it from
being thrown forward in the event of sudden
braking, etc. The vehicle is equipped with eye-
lets in the cargo space to which straps or other
cargo restraints can be attached.
WARNING
The eyelets are not to be used as passenger
restraints or as anchorages for child
restraints.
Consult your Volvo retailer about suitable
accessories for this purpose.Remember that an object weighing 44 lbs
(20 kg) produces a force of 2,200 lbs
(1,000 kg) in a head-on collision at 30 mph
(50 km/h)!
Keep the following in mind when loading the
vehicle:
•The load carrying capacity of your vehicle
is determined by factors such as the num-
ber of passengers, the amount of cargo,
the weight of any accessories that may be
installed, etc. See the section "Vehicle
loading" in the chapter "Wheel and tires"
for more detailed information.
•Load the cargo against the backrest.
•Load heavy cargo as low as possible.
•If no one is sitting in the outboard rear
seat(s), reinforce the backrest by fastening
the seat belts.
•Never load cargo above the backrest with-
out a cargo net.
WARNING
When the rear backrest(s) are folded down,
the vehicle should not be loaded to a level
higher than 2 in. (5 cm) below the upper
edge of the rear side windows. Objects
placed higher than this level could impede
the function of the inflatable curtain.

Nylon cargo net (accessory)The Volvo XC90 can be equipped with a cargo
net made of strong nylon fabric.
This net can be installed in two places:
•Behind the rear seat backrests (the second
row of seats in seven-seat models)
•Behind the front seat backrests if the rear
seat backrests (the second row of seats in
seven-seat models) have been folded
down.
