Volvo 2006 S60 - Manual (Page 54)

WARNING!
Never use the transmitter to lock the doors from inside the car
Doing so would ACTIVATE:
the break-in alarm, which would sound if one of the doors were opened
the optional interior motion and inclination alarm sensors.
Doing so would DEACTIVATE:
the moonroof and interior courtesy light controls.
the central locking buttons on the front door armrests, although the interior door handles would still function to
allow occupants to leave the car.
Disabled features would remain disabled until the remote were used again to unlock the car.
In addition, locking an occupied vehicle would hinder rapid access to the occupants in an accident or emergency.
Replacing the battery in the remote control
If the range of the transmitter is noticeably reduced, this indicates that the battery is weak 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 with your fingers.
3. Press the cover back into place. Ensure that the rubber seal is correctly positioned to help keep out moisture.
Note: The old battery should be disposed of properly at a recycling center or at your Volvo retailer.
