2006 VOLVO XC90 check engine

2006 VOLVO XC90
Many states connect a computer directly to a vehicle's OBD II system. Th\
e inspector can then read
"faults." In some states, this type of inspection has replaced the tailp\
ipe emission test.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspection for any of the followin\
g reasons.
l If your Check Engine (MIL) light is lit, your vehicle may fail inspect\
ion.
l If your vehicle's Check Engine light was lit, but went out without any a\
ction 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.
l If you had recent service that required disconnecting the battery, OBD I\
I diagnostic information may
be incomplete and "not ready" for inspection. A vehicle that is not read\
y may fail inspection.
How can I prepare for my next OBD II emission inspection?
l If your Check Engine (MIL) light is lit - or was lit but went out with\
out service, have your vehicle
diagnosed and, if necessary, serviced by a qualified Volvo technician.
l 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/ highway driving is ty\
pically needed to allow OBD II
to reach readiness. Your Volvo retailer can provide you with more inform\
ation on planning a trip.
l Maintain your vehicle in accordance with your vehicle's maintenance sche\
dule.

Reinforced lifting points
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments p\
oints should be used. They are
specially reinforced to bear the weight of the vehicle (see the illustr\
ation above). 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 positioned so that the vehicle canno\
t slide off it. Always use axle
stands or similar structures. The car's gross vehicle weight is between \
5770 lb (2630 kg) and 6080 lb
(2760 kg). Use a jack and stands rated for this weight.
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 illust\
ration).
Please note the following before you begin working on your vehicle:
Battery (see also
page 155 for more information on handling the battery)
l Ensure that the battery cables are correctly connected and tightened.
l Never disconnect the battery when the engine is running (e.g. when repl\
acing the battery).
l The battery contains acid that is both corrosive and poisonous. It is im\
portant that the battery is
handled in an environmentally friendly way. Let your Volvo retailer assi\
st you.
l Never use a fast charger to charge the battery. The battery cables shoul\
d be disconnected when
recharging.
WARNING!
The ignition system has very high voltage! The voltage in the ignition s\
ystem is dangerous!
Do not touch spark plugs, ignition cables or the ignition coil when the \
engine is running or the
ignition is switched on!
The ignition should be switched off when:
- Conducting engine tests.
- Replacing parts in the ignition system, such as spark plugs, ignition \
coil, distributor, ignition cables,
etc.
- Never try to repair any part of the SRS/SIPS/WHIPS/IC systems yourself\
. Any interference in the
system could cause malfunction and serious injury. Any work should only \
be performed by an
authorized Volvo workshop.

Belt check
Check the belt regularly to make sure it is in good condition and is cle\
an. A worn or dirty belt can cause
poor cooling and low alternator output as well as impair the operation o\
f the power steering and the air
conditioning unit.
NOTE: The drive belt is equipped with a self-tensioning mechanism and requires\
no adjustment
between changes.

WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\
r and antifreeze). CAUTION
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

l The API Service Symbol "donut" is divided into three parts:
l The upper section describes the oil's performance level.
l The center identifies the oil's viscosity.
l The lower section indicates whether the oil has demonstrated energy-cons\
erving properties in a
standard test in comparison to a reference oil.

Changing engine oil and oil filter
See the previous page for oil specifications and
page 176 for oil volumes. Refer to the Warranty and
Service Records Information booklet for information on the oil change in\
tervals.
NOTE:
l Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at ower
request and at additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This\
is especially important during
the period up to the first scheduled maintenance service.
l The car should be parked on a level surface when the oil is checked.
l If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off\
before
checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lintfree rag.

2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add appr\
oximately 1 US quart (1 liter) of
oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck\
the oil level. If necessary, add
oil until the level is near the mark.

Oil level should be between the MIN and MAX marks on the dipstick
CAUTION
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Never fill oil above the MAX mark. This could cause an increase in oil\
consumption.
- Not checking the oil level regularly can result in serious engine dama\
ge if the oil level becomes too
low.
- Always add oil of the same type and viscosity as already used.
WARNING!
Do not allow oil to spill onto or come into contact with hot exhaust pip\
e
surfaces.

Battery Maintenance
The battery in your vehicle is located under the floor of the cargo comp\
artment.
Driving habits and conditions, climate, the number of starts, etc. all a\
ffect the service life and function of
the battery. In order for your battery to perform satisfactorily, keep t\
he following in mind:
l Check the fluid level in each cell in the battery every 24 months or eve\
ry 15,000* miles (24,000 km),
whichever is sooner. The fluid should be at the level shown in the illus\
tration above (A)**.
l Use a screw driver to open the caps and a flashlight to inspect the leve\
l.
l If necessary, add distilled water. The level should never be above the i\
ndicator (A**).
l The fluid level should be checked if the battery has been recharged.
l After inspection, be sure the cap over each battery cell is securely in \
place.
l Check that the battery cables are correctly connected and properly tight\
ened. Route ventilation hose
through opening in floor (see
page 151)
l Never disconnect the battery when the engine is running, for example whe\
n changing the battery.
l The battery should be disconnected from the vehicle when a battery charg\
er is used directly on the
battery.
l However, if the battery is being charged via the connecting points in th\
e engine compartment (see
page 103), the battery must be connected.
* More frequently in warm climates.
** The level indicator inside the battery could be designed in various w\
ays. See illustration.
