2003 VOLVO S80 immobilizer

Use the switch on the front door armrests to lock/unlock the car from the inside.WARNING!
If the doors are locked while driving, this may hinder rapid access to the occupants of the car in the event of an
accident. (Also see information on "Child safety locks").
Note: To help prevent accidentally locking the keys in the car, the central locking system is designed to unlock the
doors immediately if the key is left in the ignition switch, the car is locked using the lock button on the door and the
door is then closed. A sound from the lock will be audible at this time.
Please note that this function will not unlock the doors if the engine is running.
Immobilizer (start inhibitor)
Each of the keys supplied with your car contains a coded transmitter. The code in the key is transmitted to an antenna
in the ignition switch where it is compared to the code stored in the start inhibitor module. The car will start only with
a properly coded key.
If you misplace a key, take the other keys to an authorized Volvo retailer for reprogramming as an antitheft measure.
This device complies with part 15 of the FCC rules. Operation is subject to the following condition: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
Exterior Courtesy lights
Home Safe System
When you leave your car at night, you can make use of the courtesy lighting function:
Remove the key from the ignition switch.
Pull the direction indicator lever towards the steering wheel (as when using the headlight flasher function).
Exit the car and lock the doors.
The headlights, parking lights, license plate lights and the lights in the sideview mirrors will now come on and remain
on for 30, 60 or 90 seconds (the time interval is at your discretion and can be changed by an authorized Volvo retailer).
Approach lighting
When approaching the car at night, press the yellow button in the central locking remote control (see illustration on
page 61
). This lights up the interior courtesy light, parking lights, license plate lights and the lights in the sideview
mirrors.

engage! Accelerating immediately after selecting a gear will cause harsh gear engagement and premature transmission
wear.
Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of the
automatic transmission fluid.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
WARNING!
Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the car
unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
* Your car is equipped with an electronic start inhibitor (immobilizer). The keys you received with your car are
specially coded. The code in the key is transmitted to an antenna in the ignition switch where it is compared to the
code stored in the start inhibitor module. The car can only be started if a properly coded key is used.
If two of the keys to your car are close together, e.g., on the same key ring, when you try to start the car, this could
cause interference in the immobilizer system and result in the car not starting. If this should occur, remove one of the
keys from the key ring before trying to start the car again.
pg. 74 Automatic transmission
P (Park)
Use this position when starting the engine or parking the car.
Never use P while the car is in motion.
The parking brake should also be set whenever the car is parked.
The gear selector is mechanically locked in the P position (SHIFTLOCK). To release the gear selector from this
position, the engine must be running (or the ignition key must be in position II) and the brake pedal must be
depressed.
WARNING!
Never leave the car unattended when the engine is running. If, by mistake, the gear selector is moved from P, the car
may start moving.
R (Reverse)
Never engage R while the car is moving forward.
N (Neutral)
