Emergency towing
05
210
•The gear selector must be in position N.
•Maximum speed: 50 mph (80 km/h). Do not
exceed the maximum allowable towing
speed.
•Maximum distance with front wheels on
ground: 50 miles (80 km).
•While the vehicle is being towed, try to
keep the tow rope taut at all times.
•The vehicle should only be towed in the
forward direction.
NOTE
During towing, ignition mode II should be
used so that the lighting can be switched on.
CAUTION
Vehicles with AWD (All Wheel Drive) with the
front wheels off the ground should not be
towed at speeds above 50 mph (70 km/h) or
for distances longer than 30 miles (50 km).
CAUTION
•Please check with state and local
authorities before attempting this type
of towing, as vehicles being towed are
subject to regulations regarding maxi-
mum towing speed, length and type of
towing device, lighting, etc.
•If the vehicle's battery is dead, do not
attempt to start the vehicle by pushing
or pulling it as this will damage the
three-way catalytic converter(s). The
engine must be jump started using an
auxiliary battery (see page 109).
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to pull the vehicle up onto the flat
bed or to secure the vehicle on the flat
bed. Consult the tow truck operator.
Towing vehicles with front wheel drive/
All Wheel Drive
Volvo recommends the use of flat bed equip-
ment.
•If wheel lift equipment must be used,
please use extreme caution to help avoid
damage to the vehicle. In this case, the
vehicle should be towed with the rear
wheels on the ground if at all possible.
•If it is absolutely necessary to tow the vehi-
cle with the front wheels on the ground,please refer to the towing information on
page 209.
CAUTION
•Sling-type equipment applied at the
front will damage radiator and air con-
ditioning lines.
•It is equally important not to use sling-
type equipment at the rear or apply lift-
ing equipment inside the rear wheels;
serious damage to the rear axle may
result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be
used to secure the vehicle on the flat
bed. Consult the tow truck operator.

215 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.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the
two jack attachments points should be used.They are specially reinforced to bear the weight
of the vehicle. A garage jack can also be placed
under the front of the engine support frame.
Take care not to damage the splash guard
under the engine. Ensure that the jack is posi-
tioned so that the vehicle cannot slide off it.
Always use axle stands or similar structures.
If a two-post hoist is used to lift the vehicle, the
front and rear lift arm pads should be centered
under the reinforced lift plates on the inboard
edge of the sill rail (see illustration).
Emission inspection readiness
What 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
your vehicle diagnosed and, if necessary,
serviced by a qualified Volvo technician.
•If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a
period of driving is necessary to bring the
OBD II system to "ready" for inspection. A
half-hour trip of mixed stop-and-go/high-way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.
•Maintain your vehicle in accordance with
your vehicle's maintenance schedule.

nents e.g. plugs, coil, etc.
•Do not touch any part of the distributor
ignition system while the engine is run-
ning. This may result in unintended
movements and body injury.

Battery

232
Warning symbols on the battery
Wear protective goggles.
Keep away from children.
Avoid smoking, open flames,
and/or sparks.
See the owner's manual.
Contains corrosive acid.
Risk of explosion
NOTE
A used battery should be disposed of in an
environmentally responsible manner. Con-
sult your Volvo retailer or take the battery to
a recycling station.
Handling
•Check that the battery cables are correctly
connected and tightened.
•Never disconnect the battery when the
engine is running (for example, when
replacing the battery).
•If the battery is fully discharged a number
of times, this may shorten its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
Never use a quick charger to charge the bat-
tery.
WARNING
•Never expose the battery to open flame
or electric spark.
•Do not smoke near the battery.
•Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces. If con-
tact occurs, flush the affected area
immediately with water. Obtain medical
help immediately if eyes are affected.
NOTE
The life of the battery is shortened if it
becomes discharged repeatedly.
Maintenance
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
