Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions. Observe the fol-
lowing rules:
•Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's D (Drive) position
as often as possible and avoid using "kick-
down" to help improve fuel economy.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•Remove snow tires when threat of snow or
ice has ended.
•Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•Dirty air cleaner
•Dirty engine oil and clogged oil filter
•Dragging brakes
•Incorrect front end alignment.
Some of the above mentioned items and others
are checked at the standard Maintenance
Service intervals.
CAUTION
Drive slowly and carefully if going through
standing water (i.e. flooded roadways, etc.).
Damage to the engine could result if excess
water is drawn in through the air intake sys-
tem. Never drive the vehicle in water deeper
than 18 inches (48 cm).

06 Starting and driving
Load carriers (accessory)
06
157
Positioning load carriersIf wing-shaped load carriers are used, make
sure that they are installed on the roof rails with
the rounded edge forward. Load carriers of this
type are identical and can be placed anywhere
along the roof rails.
When not in use, we recommend that the front
load carrier be placed approximately 2 inches
(5 cm) in front of the center roof rail anchorage
point and the rear load carrier approximately
1.5 inches (3.5 cm) in front of the rear rail
anchorage. This will help to reduce wind noise.
Installing load carriersMake sure that the load carriers are pressed
firmly out against the roof rail and securely
tightened place. Check regularly that any load
carriers are securely in place.
WARNING
Loads carried on the vehicle's roof should
not exceed 220 lbs (100 kg), including the
weight of the load carriers and any other
load carrying equipment (ski boxes, bicycle
racks, etc.). Excessive loads on the roof can
adversely affect the handling and roadhold-
ing characteristics of the vehicle.

5. Disconnect the positive cable and pull the
ventilation hose from the battery.
6. Lift out the old battery and put a new bat-
tery into place.
7. Connect the positive cable first.
8. Connect the negative (ground) cable.
9. Be sure that the ventilation hose (see right
column) is securely connected to the bat-
tery and that the other end of the hose is
properly routed through the ventilation
opening in the floor of the battery compart-
ment.

Ventilation hose
10. Reinstall the cover and retaining bracket
and screw it securely in place.
NOTE
After the battery has been disconnected or
replaced, lock and unlock the vehicle with
the central locking system's remote key to
reactivate such features as the power win-
dows, moonroof, courtesy lighting, etc.
WARNING
•The battery generates hydrogen gas,
which is flammable and explosive. The
battery is fitted with a ventilation hose
which vents hydrogen gas out of the
battery compartment through a ventila-
tion opening in the bottom of this com-
partment. If the battery must be
replaced, it is essential that the ventila-
tion hose is properly connected to the
battery and that it is routed through the
ventilation opening provided (see illus-
tration).
•Be sure the ventilation hose is free of
debris.
•Only use replacement batteries equip-
ped with a ventilation hose. Consult a
trained and qualified Volvo service tech-
nician.

249 Listening to satellite radio
The optional Sirius satellite system consists of
a number of high elevation satellites in geo-
synchronous orbit.
NOTE
•The digital signals from the Sirius satel-
lites are line-of-sight, which means that
physical obstructions such as bridges,
tunnels, etc, may temporarily interfere
with signal reception.
•Avoid any obstructions, such as metal-
lic objects transported on roof racks or
in a ski box, or other antennas that may
impede signals from the SIRIUS satel-
lites.
