2003 VOLVO S80 Owners Manual

Install the wheel bolts and tighten handtight. use the lug wrench, tighten crosswise(see illustration above) until all
bolts are snug.
Lower the vehicle to the ground and alternately tighten the bolts crosswise to 100 ft. lbs. (136 Nm).
Install the wheel cap (where applicable).
WARNING!
The jack must correctly engage the bar in the jack attachment (A). The car's weight must not rest on the jack
attachment (B). See illustration on page 96
.
Be sure the jack is on a firm, level, non-slippery surface.
Never allow any part of your body to be extended under a car supported by a jack.
Use the jack intended for the car when replacing a wheel. For any other job, use stands to support the side of the
car being worked on.
Apply the parking brake and put the gear selector in the (P)ark position.
Block the wheels standing on the ground, use rigid wooden blocks or large stones.
The jack should be kept well-greased.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came
with the car. The use of different size wheels can seriously damage your car's transmission.
Correct tightening torque on wheel bolts must be observed. The wheel bolts should never be greased or lubricated.
The extended, chromed wheel bolts must not be used with steel rims, as they make it impossible to fit the hub caps.

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.
WARNING!
Never use fuses with higher amperage than those stated on the following pages. Doing so could overload the car's
electrical system.

pg. 104 Replacing bulbs
Replacing high/low beam headlight bulbs
The headlight bulbs must be replaced from the engine compartment.
CAUTION:
Do not touch the glass on halogen bulbs with your fingers. Grease, oil or any other impurities can be carbonized
onto the bulb and cause damage to the reflector.
Be sure to use bulbs of the correct type and voltage.
Removing a defective bulb
ProCarManuals.com

To remove a defective bulb:
Switch off the ignition.
Open the hood.
Remove the plastic cover over the bulb (1) by turning it counterclockwise.
Remove the connector (2).
Loosen the retaining spring (3) by first moving it to the right and then moving it down, out of the way.
Pull out the defective bulb. Note the position of the guide lug on the base of the bulb (4).
Installing a new bulb
To install a new bulb:
Insert the new bulb, without touching the glass, with the guide lug upward (1). The bulb will only seat properly in
this position.
Move the retaining spring up and push it slightly to the left until it seats properly (2).
Press the connector into place on the bulb (3).
Reinstall the plastic cover and turn it clockwise until it is correctly in place (4). "TOP" must be upward.
NOTE: If the vertical aim of your headlights needs to be adjusted for any reason (e.g., towing a trailer for extended
periods), this should be done by an authorized Volvo retailer.
