1. Malfunction indicator light
As you drive, a computer called
On-Board Diagnostics II (OBDII)
monitors your car's engine, trans-
mission, electrical and emission
systems.
The CHECK ENGINE light will light up if the
computer senses a condition that potentially
may need correcting. When this happens,
please have your car checked by a trained and
qualified Volvo service technician as soon as
possible.
A CHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a change
in your car's behavior. Even so, an uncorrected
condition could hurt fuel economy, emission
controls, and drivability. Extended driving with-
out correcting the cause could even damage
other components in your car.
NOTE
Canadian models are equipped with the
second symbol.
2. Anti-lock Brake system (ABS)If the warning light comes on, there
is a malfunction of the ABS system
(the standard braking system will
still function).
The vehicle should be driven to a
trained and qualified Volvo service
technician for inspection, see
page 154 for additional informa-
tion.
NOTE
Canadian models are equipped with the
second symbol.
3. Rear fog lightThis symbol indicates that the rear
fog light (located in the driver's
side taillight cluster) is on.
4. Stability system DSTCThis indicator symbol flashes when
the DSTC (Dynamic Stability and
Traction control system) is actively
working to stabilize the car, see
page 158 for more detailed infor-
mation.
5. Tire Pressure Monitoring SystemThis system monitors inflation
pressure in the tires. See page
201 for more information.
6. Fuel level warning lightWhen this light comes on, the vehi-
cle should be refueled as soon as
possible.

Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:
•Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•Remove snow tires when threat of snow or
ice has ended.
•At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•Dirty air cleaner
•Dirty engine oil and clogged oil filter
•Dragging brakes
•Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:
1. Close the windows.
2. Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handling
At the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.
Handling, roadholding
Vehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.
Driving through water
The vehicle can be driven through water up to
a depth of approximately 9 in. (25 cm), at a
maximum speed of 6 mph (10 km/h).
•Take particular care when driving through
flowing water.
•Clean the electrical connections for trailer
wiring after driving in mud or water
•When driving through water, maintain low
speed and do not stop in the water.

179 Inflation placard

Tire inflation placard
Check tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found beginning
on page 181. A tire inflation pressure placard
is also located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening). This plac-
ard indicates the designation of the factory-
mounted tires on your vehicle, as well as load
limits and inflation pressure.
NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the car at the
factory only.
Use a tire gauge to check the tire inflation pres-
sure, including the spare, at least once a month
and before long trips. You are strongly urged
to buy a reliable tire pressure gauge, as auto-
matic service station gauges may be inaccu-
rate.
Use the recommended cold inflation pressure
for optimum tire performance and wear.
Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING
•Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blowout," with unexpected loss of
vehicle control and increased risk of
injury.
•Under-inflated tires reduce the load car-
rying capacity of your vehicle.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Checkyour tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicle's tire information placard or certifi-
cation label.
Checking tire pressure
Cold tiresInflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when
they have the same temperature as the sur-
rounding (ambient) air.
This temperature is normally reached after the
car has been parked for at least 3 hours.
After driving a distance of approximately 1 mile
(1.6 km), the tires are considered to be hot. If
you have to drive farther than this distance to
pump your tire(s), check and record the tire
pressure first and add the appropriate air pres-
sure when you get to the pump.
If checking tire pressure when the tire is hot,
never "bleed" or reduce air pressure. The tires
are hot from driving and it is normal for pres-
sures to increase above recommended cold
pressures. A hot tire at or below recommended
cold inflation pressure could be significantly
under-inflated.

To check inflation pressure:1. Remove the cap from the valve on one tire,
then firmly press the tire gauge onto the
valve.
2. Add air to reach the recommended air
pressure
3. Replace the valve cap.
4. Visually inspect the tires to make sure there
are no nails or other objects embedded
that could puncture the tire and cause an
air leak.
5. Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregular-
ities.
6. Repeat this procedure for each tire, includ-
ing the spare.
NOTE
•If you overfill the tire, release air by
pushing on the metal stem in the center
of the valve. Then recheck the pressure
with your tire gauge.
•Some spare tires require higher inflation
pressure than the other tires. Consult
the tire inflation tables, see page 181,
or see the inflation pressure placard.
Load ratingsSee page 182 for an explanation of the load
rating on the sidewall of the tire.
Speed ratingsThe speed ratings in the tables translate as fol-
lows:

Federal law mandates that tire manufacturers
place standardized information on the sidewall
of all tires (see the illustration).
The following information is listed on the tire
sidewall:
The tire designation:
NOTE
Please be aware that the following tire des-
ignation is an example only and that this
particular tire may not be available on your
vehicle.
215: The width of the tire (in millimeters)
from sidewall edge to sidewall edge. The
larger the number, the wider the tire.
65: The ratio of the tire's height to its width
in percent.
R: Radial tire.
15: The diameter of the wheel rim (in
inches).
95: The tire's load index. In this example, a
load index of 95 equals a maximum load of
1521 lbs (690 kg).
H: The tire's speed rating, or the maximum
speed at which the tire is designed to be
driven for extended periods of time, carry-
ing a permissible load for the vehicle, and
with correct inflation pressure. For exam-
ple, H indicates a speed rating of 130 mph
(210 km/h).
NOTE
The tire's load index and speed rating may
not appear on the sidewall because they are
not required by law.
M+S or M/S = Mud and Snow, AT = All
Terrain, AS = All Season
U.S. DOT Tire Identification Number
(TIN): This begins with the letters "DOT"
and indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was manufac-
tured, the next two are the tire size code
and the last four numbers represent the
week and year the tire was built. For exam-
ple, 1510 means that the tire was manu-
factured during week 15 of 2010. The num-
bers in between are marketing codes used
at the manufacturer's discretion. This infor-
mation helps a tire manufacturer identify a
tire for safety recall purposes.
Tire Ply Composition and Material
Used: Indicates the number of plies indi-
cates or the number of layers of rubber-
coated fabric in the tire tread and sidewall.
Tire manufacturers also must indicate the
ply materials in the tire and the sidewall,
which include steel, nylon, polyester, and
others.
Maximum Load: Indicates the maximum
load in pounds and kilograms that can be
carried by the tire. Refer to the vehicle's tire
information placard located on the B-Pillar
or the driver's door for the correct tire pres-
sure for your vehicle.
