2005 VOLVO S80 ECU

To buckle:
Pull the belt out far enough to insert the latch plate into the receptacle until a distinct click is heard. The seat belt
retractor is normally "unlocked" and you can move freely, provided that the shoulder belt is not pulled out too far. The
retractor will lock up as follows:
if the belt is pulled out rapidly
during braking and acceleration
if the vehicle is leaning excessively
when driving in turns
For the seat belt to provide maximum protection in the event of an accident, it must be worn correctly. When wearing
the seat belt remember:
The belt should not be twisted or turned.
The lap belt must be positioned low on the hips (not pressing against the abdomen).
Make sure that the shoulder belt is rolled up into its retractor and that the shoulder and lap belts are taut.
The seat belts are equipped with tensioners that reduce slack in the seat belts. These tensioners are triggered in
situations where the airbags deploy.
The front seat belts also include a tension reducing device which, in the event of a collision, limits the peak forces
exerted by the seat belt on the occupant.
Before exiting the car, check that the seat belt retracts fully after being unbuckled.
If necessary, guide the belt back into the retractor slot.
NOTE: Legislation in your state or province may mandate seat belt usage.

Lap portion of the belt should sit low

Folding rear seat backrest
The rear seat backrest is split into two sections. Each section can be folded independently to allow you to transport
long objects.
To fold down the backrest(s):
Pull the release control handle(s) in the trunk to release the backrest(s) (see illustration above). If the outboard rear
head restraints are folded down, they should be returned to the upright position before folding the backrest down. It
may be necessary to manually adjust the center head restraint.
Fold the backrest down.
WARNING!
All S80 cars feature 60/40 split fold-down rear seats. This function is performed by handles inside the trunk, and
also provides a means for children and adults to enter the passenger compartment in the event they become locked
inside the trunk.
Adults are advised to familiarize themselves with the operation and location of the release handles.
To fold down the rear seats from inside the trunk, pull the release control handles located on either side of the trunk.
WARNING!
Keep vehicle doors and the luggage compartment locked and keep keys out of a child's reach. Unsupervised
children could lock themselves in an open trunk and risk injury. Children should be taught not to play in vehicles.
On hot days, the temperature in the trunk or vehicle interior can rise very quickly. Exposure of people to these
high temperatures for even a short period of time can cause heat-related injury or death. Small children are
particularly at risk.
WARNING!
When the backrest is returned to the upright position, check that it is properly locked in place. Return the head
restraints to the upright position.
Long loads should always be securely anchored to help avoid injury in the event of a sudden stop.
Always turn the engine off and apply the parking brake when loading/unloading the vehicle.
Place the transmission in the P (PARK) position to help prevent inadvertent movement of the gear selector.

HomeLink® Universal Transceiver (option)
pg. 169 HomeLink® Universal Transceiver (option)
HomeLink® Universal Transceiver
HomeLink® is an advanced system that can be programmed to learn the codes of three different remote controlled-
devices (e.g., garage door openers, remote lighting, entry door lock). HomeLink®'s sun visor-mounted transceiver,
powered by your car's electrical system, may then be used in place of your hand -held remote controls.
NOTE: For your security, the HomeLink® Universal Transceiver is designed to not function if the car has been
locked from the outside .
Programming the transceiver
1. The ignition switch must be turned to the "accessory" position (II) before programming the HomeLink® Universal
Transceiver.
2. Begin by erasing all 3 factory default channels. Hold down the two outside buttons (buttons 1 and 3 in the
illustration) on the HomeLink® Universal Transceiver for about 20 seconds, until HomeLink®'s indicator light begins
to flash. Then release the buttons.
3. Hold your hand -held transmitter (garage door opener, for example) 2 to 5 in. (5 to 12 cm) away from the
HomeLink® surface, keeping the indicator light in view. For placement questions, contact HomeLink® toll-free 1-
800-355-3515 (Internet: www.HomeLink.com
).
4. Using two hands, push and hold both your hand -held transmitter's button and the transceiver button you wish to
program. The indicator light will flash first slowly, then rapidly. Rapid flashing tells you the HomeLink® button has
been successfully programmed. Release both buttons.
5. If you are programming a rolling code-equipped device (e.g., garage door opener or entry door lock), refer to
"Programming rolling codes" on the next page to complete the programming process.
