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 STC or DSTCThis indicator symbol flashes when
the STC (Stability and Traction
control system) or the DSTC
(Dynamic Stability and Traction
control system) is actively working
to stabilize the car, see page 158 for more
detailed information.
5. Tire Pressure Monitoring SystemThis system monitors inflation
pressure in the tires. See page
200 for more information.
6. Fuel level warning lightWhen this light comes on, the vehi-
cle should be refueled as soon as
possible.

141 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.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 9 in. (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•If the engine has been stopped while the
car is in water, do not attempt to restart
the engine. Have the car towed out of
the water.
Cold weather precautions
If you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to –31 °F
(–35 °C). See section "Coolant". The use of
"recycled" antifreeze is not approved byVolvo. Different types of antifreeze must
not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to help protect your vehicle
during cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 274 for more
information.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer.

179 Inflation placard
G032513
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. Repeat this procedure for each tire, includ-
ing the spare.
5. 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.
6. Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregular-
ities.
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 183 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.
