The charging cable has a circuit breaker that
helps protect against current overloads and ther-
mal overheating.
WARNING Charging the hybrid battery may only be done
from approved, grounded 120/240 V outlets
(AC, alternating current). If the electrical cir-
cuit or electrical socket's capacity is not
known, let a licensed electrician inspect the
electrical circuit's capacity. Using a charge
level that exceeds the electrical circuit's or
electrical outlet's capacity may start a fire or
damage the electrical circuit.
WARNING
The charging cable's residual current
breaker helps protect the vehicle's charg-
ing system but cannot ensure that an cur-
rent overload will never occur.
Never use visibly worn or damaged elec-
trical sockets. Doing so could lead to fires
or serious injury.
Never connect the charging cable to an
extension cord.
Maintenance or replacement of the hybrid
battery may only be performed by a
trained and qualified Volvo service techni-
cian.
If the charging cable's residual current device is
triggered, the blue indicator light in the charging
module will not illuminate when the charging
cable is plugged into an electrical outlet (or the
red warning light will glow steadily). Have the out-
let checked by a licensed electrician or try using
another wall outlet.

STARTING AND DRIVING
442Maintenance of the brake system
Regularly check the brake system components
for wear.
To keep the vehicle as safe and reliable as possi-
ble, follow the Volvo service schedule specified in
the Warranty and Maintenance Records Informa-
tion booklet. New and replaced brake pads and
brake discs do not provide optimal braking effect
until they are "broken in" by driving a few hun-
dred kilometers (miles). Compensate for the
reduced braking effect by applying greater pres-
sure to the brake pedal. Volvo recommends only
using brake pads approved for your Volvo.
CAUTION The brake system's components should be
regularly checked for wear.
Contact a workshop for advice on how to do
this or let a workshop perform the inspection
- an authorized Volvo workshop is recom-
mended.

Brakes (p. 439) Parking brake
The parking brake helps keep the vehicle sta-
tionary by mechanically locking two wheels.
The parking brake controls are located in the tunnel
console between the seats.
When the electric parking brake is being applied,
a faint sound can be heard from the brake's elec-
tric motor. This sound can also be heard during
the automatic function check of the parking
brake.
If the vehicle is stationary when the parking brake
is applied, it will only be applied to the rear
wheels. If it is applied while the vehicle is moving,
the normal brakes will be used on all four wheels.
Braking will be transferred to only the rear
wheels when the vehicle is almost stopped.

WHEELS AND TIRES
566Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY REQUIRE-
MENTS IN ADDITION TO THESE GRADES.
Quality grades can be found, where applica-
ble, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one half (1 ½) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and many depart significantly from the norm due
to variation in driving habits, maintenance practi-
ces and differences in road characteristics and
climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering (turn-
ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and exces-
sive temperature can lead to sudden tire failure.
The grade C corresponds to a minimum level of
performance that all passenger vehicle tires must
meet under the Federal Motor Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-infla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
tire failure.

function, the telltale will flash for approximately
one minute and then remain continuously illumi-
nated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, 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 ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressure
warning symbol is shown in the instrument panel
along with a message.
Tire pressure low Check tires, calibrate
after fill
Tire pressure system Temporarily
unavailable
Tire pressure system Service required
To keep in mind
Always calibrate the system after changing
wheels or adjusting tire pressure. See the tire
pressure placard on the driver's side B pillar
for Volvo-recommended tire pressures.
If you switch to a tire of another size than the
factory-mounted tires, the system must be
calibrated for these tires to avoid false warn-
ings.
If a spare wheel 8
is used, it is possible that
the tire pressure monitoring system will not
work correctly due to the differences
between the wheels.
The system does not replace the need for
regular tire inspection and maintenance.
It is not possible to deactivate the tire pres-
sure monitoring system.
WARNING
Incorrect inflation pressure could lead to
tire failure, which could cause the driver
to lose control of the vehicle.
The system cannot predict sudden tire
damage.

ify time-tested and proven Genuine Volvo Parts
and Accessories.
The Federal Clean Air Act - U.S.
The Federal Clean Air Act requires vehicle manu-
facturers to furnish written instructions to the ulti-
mate purchaser to assure the proper servicing
and function of the components that control
emissions. These services, which are listed in the
"Warranty and Service Records Information"
booklet, are not covered by the warranty. You will
be required to pay for labor and material used.
Maintenance
Your Volvo passed several major inspections
before it was delivered to you, in accordance with
Volvo specifications. The maintenance proce-
dures outlined in the Warranty and Service
Records Information booklet, many of which will
positively affect your vehicle's emissions, should
be performed as indicated. It is recommended
that receipts for vehicle emission maintenance be
retained in case questions arise concerning
maintenance. Inspection and maintenance should
also be performed anytime a malfunction is
observed or suspected.

Periodic maintenance helps minimize
emissions
NOTE
Refer to your Service and Warranty Book-
let for a comprehensive service and main-
tenance schedule up to 240,000 km
(150,000 miles). This program contains
inspections and services necessary for
the proper function of your vehicle and
includes components that affect vehicle
emissions.
The Warranty and Service Records Infor-
mation booklet also contains detailed
information concerning the warranties
that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized
engine management system. It stores diagnostic
information about your vehicle's emission con-
trols. 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 perma-
nent or temporary. OBD II will store a message
about any fault.
Emission inspection readiness
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 inspec-
tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection
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. Two half-
hour trips of mixed stop-and-go/highway
driving are typically needed to allow OBD II to
reach readiness. Your Volvo retailer can pro-
vide you with more information on planning a
trip.
Maintain your vehicle in accordance with your
vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervals
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 taillights.
