CAUTION
•
Do not refuel with the engine running
1.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
•
Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much
fuel in the tank in hot weather conditions
can cause the fuel to overflow. Overfill-
ing could also cause damage to the
emission control systems.
Emission controlsThree-way catalytic converter•
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will helpavoid malfunctions that could damage the
three-way catalytic converter.
•
Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•
Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•
Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.

IntroductionThe load carrying capacity of your vehicle is
determined by factors such as the number of
passengers, the amount of cargo, the weight
of any accessories that may be installed, etc.
To increase loading space, the rear seat backr-
ests can be folded down, See page 81.
When loading the cargo area, keep the follow-
ing in mind:•
Load objects in the cargo area against the
backrest whenever possible.
•
Unstable loads can be secured to the load
anchoring eyelets with straps or web lash-
ings to help keep them from shifting.
•
Stop the engine and apply the parking
brake when loading or unloading long
objects. The gear selector can be knocked
out of position by long loads, which could
set the vehicle in motion.
WARNING
•
Stop the engine, put the gear selector in
P, and apply the parking brake when
loading or unloading long objects.
•
The vehicle's driving characteristics
may change depending on the weight
and distribution of the load.
•
A 44-pound (20 kg) object produces a
force of 2,200 pounds (1,000 kg) in a
headon collision at 30 mph (50 km/h).
•
The cargo area and rear seat should not
be loaded to a level higher than 2 in.
(5 cm) below the upper edge of the rear
side windows. Objects placed higher
than this level could impede the func-
tion of the Volvo Inflatable Curtain.

brake and put the gear selector in P
when loading and unloading the vehicle.
Cargo area floor rails and hooks
G018135
Load secured in upper and lower hooks
The floor of the cargo compartment has rails
on opposite sides of the vehicle equipped with
hooks for anchoring loads with straps, nets,
etc.Cleaning the railsDirt or other small objects that collect in the
rails can make moving, locking, unlocking, and
removing the hooks more difficult. Objects can
be removed from the rails with a vacuum
cleaner, and the rails can be cleaned with a
moist cloth.Moving the load anchoring hooks

IntroductionVolvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 271 for the maximum trailer and
tongue weights recommended by Volvo.•
Observe the legal requirements of the
state/province in which the vehicles are
•
All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•
Increase tire pressure to recommended
full. See the tire inflation tables on pages
248 and 249.
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
Maximum speed when towing a trailer:
50 mph (80 km/h).
•
Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watchedwhen driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•
If the automatic transmission begins to
overheat, a message will be displayed in
the text window.
•
Avoid overload and other abusive opera-
tion.
•
Hauling a trailer affects handling, durabil-
ity, and economy.
•
It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball and drawbar assembly
when the hitch is not being used.
•
Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•
Trailer hitches attaching to the vehicle
rear axle must not be used.
•
Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest author-
ized Volvo retailer for correct installa-
tion.
•
When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

mendations for wheel chocking.
•
When starting on a hill, put the gear
selector in D before releasing the park-
ing brake. See also page 115 for more
detailed information about starting off
on a hill while towing a trailer.
•
If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
•
The drawbar assembly/trailer hitch may
be rated for trailers heavier than the
vehicle is designed to tow. Please
adhere to Volvo's recommended trailer
weights.
•
Avoid driving with a trailer on inclines of
more than 15 %.
Trailer cableAn adapter is required if the vehicle's trailer
hitch has a 13-pin connector and the trailer has
7 pins. Use an adapter cable approved by

06 Maintenance and specifications
Maintaining your car
06``217 Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.Each time the car is refueled:•
Check the engine oil level.
•
Clean the windshield, windshield wipers,
headlights, and tail lights.
Monthly:•
Check cold tire pressure in all tires. Inspect
the tires for wear.
•
Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
•
Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•
Wipe driver information displays with a soft
cloth.
•
Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult your Volvo
retailer for additional information.
As needed:Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup
of dirt, and corrosion that can be caused by salt
residues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other pla-
ces where they may collect.
NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.Emission inspection readinessWhat is an Onboard Diagnostic System
(OBD II)?OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How do states use OBD II for emission
inspections?Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type of
inspection has replaced the tailpipe emission
test.How can my vehicle fail OBD II emission
inspection?Your vehicle can fail OBD II emission inspec-
tion for any of the following reasons.•
If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
•
If your vehicle's Check Engine light was lit,
but went out without any action on your
part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending
on the inspection practices in your area.
•
If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?•
If your Check Engine (MIL) light is lit – or
was lit but went out without service, have
