pg. 56 Remote keyless entry system
Remote keyless entry system
Your car is equipped with a remote control transmitter. This transmitter uses a radio frequency which will allow
"keyless" entry into the passenger compartment or the trunk. You will be supplied with two coded key ring
transmitters, which will enable you to lock/unlock all doors and the trunk from a distance of 10-15 feet (3-5 meters).
On vehicles equipped with an alarm, the alarm will also be activated/deactivated by this system.
The car can also be locked/unlocked with the key.
As an extra security precaution in certain situations (valet parking, etc.), Volvo recommends that the transmitter not be
included when the keys are given to anyone. The service key can be used instead. If one of the transmitters is
misplaced, contact the nearest authorized Volvo retailer for assistance.

Remote keyless entry system and driver's seat

· The next time you unlock the driver's door with the same remote control (the one you used to lock the doors with)
and open the driver's door , the driver's seat will automatically move to the position in which you left it.
The seat will move to this position even if someone else has adjusted the seat since you last drove the car.
NOTE:
· This feature will work in the same way with all of the remote control transmitters (up to 3) that you use with your
car.
· This feature will not function if you lock your car with the key.
This device complies with FCC rules Part 15. Operation is subject to the following two conditions: (1) This device
may not cause harmful interference and (2) this device must accept any interference that may be received, including
interference that may cause undesired operation.
pg. 57 Remote keyless entry system
WARNING!
Volvo does not recommend using the transmitter to lock the doors from inside the car. On cars equipped with an
alarm, the alarm would be activated and would sound when one of the doors is opened. The doors must not be
locked using the remote transmitter while the vehicle is occupied. In case of an accident, this may hinder rapid
access to the occupants of the vehicle. The alarm will also sound on models equipped with this feature.
NOTE :
· If the doors are unlocked, the locks will automatically reengage (re-lock) and the alarm will reset after 2 minutes
unless a door has been opened.
· Airbag deployment will automatically unlock the doors.
· The lock/unlock and alarm features can also be utilized by using the keys. See page 54
.
· To avoid leaving your keys in the car, make a habit of always locking the car with the remote control.

Remote keyless entry system - replacing batteries
Each remote transmitter is powered by a three-volt, CR 2032 battery.
If the range of the transmitter is noticeably reduced, this indicates that the battery is weak and should be replaced.
Replacement: Remove the screw on the back of the transmitter cover. Replace the battery. Reinstall the cover and
tighten the screw to help protect the transmitter.
NOTE: The old battery should be disposed of properly at a recycling center or at your Volvo retailer.

The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not include
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law. WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible
tire failure.
pg. 84 Changing wheels
Insert flat end of lug wrench and turn/pull straight out
Changing wheels
The spare wheel is located under the carpet on the trunk floor. The jack and crank are secured in the wheel recess.
There are two jack attachment points on each side of the car.
To change a wheel:
· Engage the parking brake.
· Put the gear selector in (P)ark.
· Remove the wheel cap (where applicable) using the lug wrench in the tool kit.
· With the car still on the ground, use the lug wrench to loosen the wheel bolts 1/2 1 turn. Turn the bolts
counterclockwise to loosen.

Replacing fuses
If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment *
B - Fuse box in the passenger compartment
C - Relays/fuse box in the trunk *
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each
fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you
will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal
wire to see if it is broken. If so, put in a new
fuse of the same color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the passenger
compartment. If fuses burn out repeatedly, have the electrical system inspected by an authorized Volvo retailer.
* The relays and main fuses in the engine compartment and trunk should only be replaced by an authorized
Volvo retailer. You can, however, replace the ordinary fuses if necessary.
pg.89 Fuses in the engine compartment
Relays/fuses in the engine compartment
The relay/fuse box in the engine compartment contains 8 main fuses and space for 21 ordinary fuses. The main fuses
should only be replaced by an authorized Volvo retailer. You can, however, replace the ordinary fuses if necessary.
Be sure to replace a blown fuse with a new one of the same color and amperage (written on the fuse).

Fuses in the trunk
The fuses in the trunk are located on the left side under the covering material. The main fuses, under a cover held in
place by screws, should only be replaced by an authorized Volvo retailer. When replacing a blown ordinary fuse,
be sure to replace it with a new one of the same color and amperage (written on the fuse).
