Returning the spare wheel to the storage
compartment
1. Use the crank (turn it counterclockwise) to
lower the spare wheel's retaining cable.
2. Pass the toggle at the end of the cable
through the center hole in the spare wheel.Pivot the toggle 90 degrees so that when
raised, the wheel will rest on the toggle.
3. Retract the retaining cable slightly by
slowly turning the crank clockwise several
times.
4. Position the wheel so that it is not obstruc-
ted by components in the exhaust system.
5. Continue to raise the wheel by turning the
crank clockwise. Raise the wheel a little bit
at a time and guide it around the rear axle

Jack attachment points
Jack attachmentsThere are two attachment points for the jack on
each side of the vehicle. These attachment
points are under the center of each door.
WARNING
There is an attachment point on each side
of the vehicle located under the pillars
between the front and rear doors. This point
is used during the production process only,
and is NOT intended for attaching the jack.

WARNING
The undersides of accessory running
boards are not intended for attaching the
jack.
Changing a wheel1. Park the vehicle on a firm, level, non-slip-
pery surface.
2. Engage the parking brake and put the gear
selector in the Park position.
3. Loosen the wheel bolts by exerting down-
ward pressure on the lug wrench.4. Remove the wheel cover (where applica-
ble) using the lug wrench in the tool bag.
5. With the wheels still on the ground, use the
lug wrench to loosen the wheel bolts ½ – 1
turn. Turn the bolts counterclockwise to
loosen the bolts.

Attaching the jack
6. Place the jack on the ground, under one of
the attachment points (see the illustration)
and crank while simultaneously guiding the
jack's attachment bracket onto the attach-
ment point (see illustration) The base of the
jack must be flat on a level, firm, non-slip-
pery surface. Before raising the vehicle,

check that the jack is still correctly posi-
tioned in the attachment.
7. Raise the vehicle until the wheel to be
changed is lifted off the ground.
8. Unscrew the wheel bolts completely and
carefully remove the wheel so as not to
damage the threads on the studs.
NOTE
To avoid excessive wear and the necessity
of rebalancing, mark and reinstall wheels in
the same location and position as before
removal. To lessen the chance of imbal-
ance, each wheel hub is equipped with a
guide stud to ensure that a removed wheel
can be reinstalled in its original position (as
when changing over to winter tires/wheels).
CAUTION
•The vehicle must not be driven with
wheels of different dimensions or with a
spare tire other than the one that came
with the vehicle. The use of different size
wheels can seriously damage your vehi-
cle's transmission.
•Correct tightening torque on wheel
bolts must be observed.
•The wheel bolts should never be
greased or lubricated.
•Extended, chromed wheel bolts must
not be used with steel rims, as they
make it impossible to fit the hub caps.
Installing the wheel1. Clean the contact surfaces on the wheel
and hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel bolts and tighten hand-
tight. Using the lug wrench, tighten cross-
wise until all bolts are snug.
4. Lower the vehicle to the ground and alter-
nately tighten the bolts crosswise to
103 ft.lbs. (140 Nm).
5. Install the wheel cover (where applicable).
WARNING
•The jack must correctly engage the bar
in the jack attachment. The vehicle's
weight must not rest on the jack attach-
ment. See illustration "Attaching the
jack" on the previous page.
•Be sure the jack is on a firm, level, non-
slippery surface.
•Never allow any part of your body to be
extended under a vehicle supported by
a jack.
•Use the jack intended for the vehicle
when replacing a wheel. For any other
job, use stands to support the side of
the vehicle 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
and clean, and should not be damaged.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.
The jack and tools should be returned to their
storage spaces. The jack should be cranked
down fully so that it fits into the intended space.

07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
07
194
The tire pressure monitoring system1 uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is mov-
ing at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.
USA – FCC ID: MRXG403MA4A
This device complies with part 15 of the FCC
rules. Operation is subject to the following
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received,
including interference that may cause unde-
sired operation.
When low inflation pressure is detected,
TPMS will light up the tire pressure warning
light (also referred to as a telltale) in the
instrument panel (see page 61), and will dis-
play a message in the text window. The
wording of this message is determined by
the degree of inflation pressure loss.
AOn certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS
will light up the tire pressure warning light
(also referred to as a telltale) in the instrumentpanel and will display one of the following mes-
sages in the text window:
LOW TIRE PRESS.
CHECK TIRES or VERY LOW TIRE
PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflatedtire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
1This system is standard on U.S. models and optional on Canadian models

ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.
NOTE
TPMS indicates low tire pressure but does
not replace normal tire maintenance. For
information on correct tire pressure, please
refer to the tire inflation pressure table in this
chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:
1. Use a tire pressure gauge to check the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
table see page 177).
3. Drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and the
warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Changing wheels with TPMSPlease note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:
•Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
•If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
•If wheels without TPMS sensors are moun-
ted on the vehicle, TIRE PRESS SYST
SERVICE REQUIRED will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
•Once TPMS sensors are properly installed,
the warning message should not reappear.
•Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.
Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.
NOTE
If a tire is changed or if the TPMS sensor is
moved to another wheel, the sensor’s seal,
nut and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press
the pump's mouthpiece straight onto the
valve to help avoid bending or otherwise
damaging the valve.
Recalibrating TPMS (Canadian models
only)
In certain cases, it may be necessary to reca-
librate TPMS to conform to Volvo's recom-
mended tire inflation pressures (see the infla-
tion pressure table on page 177), for example,
if higher inflation pressure is necessary when
transporting heavy loads, etc.
To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure and
turn the ignition key to position I or II (see
page 141 for additional information).
3. Turn the thumb wheel on the left-side
steering wheel lever until
Tire pressure
Calibration appears in the display.
4.
Press and hold the Reset button on the
left-side steering wheel lever until
TIRE
PRESSURE CALIBRATED is displayed.

09 Maintenance and servicing
Maintaining your vehicle09

209 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 vehicle 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 a trained
and qualified Volvo service technician for
additional information.
As needed
•Wash the vehicle, including the undercar-
riage, 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 places where they may collect.
•Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvote-
chinfo.com.
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 ofinspection 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-
