Seat belt reminder
This symbol comes on for approximately 6 sec-
onds if the driver has not fastened his or her
seat belt.
Generator not charging
This symbol comes on during driving if a fault
has occurred in the electrical system. Contact
an authorized Volvo workshop.
Engine temperatureEngine overheating can result from low oil or
coolant levels, towing or hard driving at high
heat and altitude, or mechanical malfunction.
Engine overheating will be signaled with text
and a red warning triangle in the middle of the
instrument display. The exact text will depend
on the degree of overheating. It may range from
High engine temp Reduce speed to High
engine temp Stop engine. If appropriate,
other messages, such as Coolant level low,
Stop safely will also be displayed. If your
engine does overheat so that you must stop the
engine, always allow the engine to cool before
attempting to check oil and coolant levels.
See page 312 for more information.
Fault in brake system
If this symbol lights, the brake fluid level may
be too low. Stop the vehicle in a safe place and
check the level in the brake fluid reservoir, see
page 312. If the level in the reservoir is belowMIN, the vehicle should be transported to an
authorized Volvo workshop to have the brake
system checked.
Canadian models are equipped with this
symbol.
If the
and symbols come on at the
same time, there may be a fault in the brake
force distribution system.
1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
•If both symbols extinguish, continue driv-
ing.
•If the symbols remain on, check the level in
the brake fluid reservoir, see page 312. If
the brake fluid level is normal but the sym-
bols are still lit, the vehicle can be driven,
with great care, to an authorized Volvo
workshop to have the brake system
checked.
•If the level in the reservoir is below MIN, the
vehicle should be transported to an author-
ized Volvo workshop to have the brake
system checked.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a warning message
is displayed in the text window: DO
NOT DRIVE. Have the vehicle towed to
a trained and qualified Volvo service
technician and have the brake system
inspected.
•If the ABS and Brake system lights are
on at the same time, there is a risk of
reduced vehicle stability.
Warning symbol
The red warning symbol lights up to indicate a
problem related to safety and/or drivability. A
message will also appear in the main instru-
ments panel's display. The symbol remains
visible until the fault has been rectified but the
text message can be cleared with the READ
button, see page 125. The warning symbol can
also come on in conjunction with other sym-
bols.
Action:
1. Stop in a safe place. Do not drive the vehi-
cle further.
2. Read the information on the information
display. Implement the action in accord-
ance with the message in the display. Clear
the message using READ.

Starting the engine
03

* Option/accessory, for more information, see Introduction.109 Start
Ignition switch with remote key inserted ( see
page 80 for more information on ignition modes)
WARNING
Before starting the engine:
•Fasten the seat belt.
•Check that the seat, steering wheel and
mirrors are adjusted properly.
•Make sure the brake pedal can be
depressed completely. Adjust the seat
if necessary.
WARNING
•Never use more than one floor mat at a
time on the driver's floor. An extra mat
on the driver's floor can cause the
accelerator and/or brake pedal to
catch. Check that the movement of
these pedals is not impeded.
•Volvo's floor mats are specially manu-
factured for your car. They must be
firmly secured in the clips on the floor so
that they cannot slide and become trap-
ped under the pedals on the driver's
side.
1. Press the remote key into the ignition slot
as far as possible, with the metallic key
blade pointing outward (not inserted into
the slot)
1.
2.
Depress the brake pedal

3.
Press and release the START/STOP
ENGINE button. The autostart function will
operate the starter motor until the engine
starts or until its overheating function stops
it.The starter motor operates for a maximum
of 10 seconds. If the engine has not
started, repeat the procedure.
NOTE
Keyless drive*
To start a vehicle equipped with the keyless
drive feature, one of the remote keys must
be in the passenger compartment. Follow
the instructions in step 3 to start the vehicle.
1On vehicles with the optional keyless drive, it is only necessary to have a remote key in the passenger’s compartment.2If the vehicle is moving, it is only necessary to press the START/STOP ENGINE button to start the vehicle.

WARNING
•Always remove the remote key from the
ignition slot when leaving the vehicle,
especially if there are children in the
vehicle.
•Never open the driver's door while driv-
ing or when the vehicle is being towed.
The steering lock could otherwise be
activated, making it impossible to steer
the vehicle. On vehicles with the
optional keyless drive, never remove
the remote key from the vehicle while
driving or during towing.
•Always place the gear selector in Park
and apply the parking brake before
leaving the vehicle. Never leave the
vehicle unattended with the engine run-
ning.
•Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The
exhaust gases contain carbon monox-
ide, which is invisible and odorless but
very poisonous.
NOTE
•After a cold start, idle speed may be
noticeably higher than normal for a
short period. This is done to help bring
components in the emission control
system to their normal operating tem-
perature as quickly as possible, which
enables them to control emissions and
help reduce the vehicle's impact on the
environment
3.
CAUTION
•When starting in cold weather, the auto-
matic transmission may shift up at
slightly higher engine speeds than nor-
mal until the automatic transmission
fluid reaches normal operating tem-
perature.
•Do not race a cold engine immediately
after starting. Oil flow may not reach
some lubrication points fast enough to
prevent engine damage.
•The engine should be idling when you
move the gear selector. Never acceler-
ate until after you feel the transmission
engage. Accelerating immediately after
selecting a gear will cause harsh
engagement and premature transmis-
sion wear.
•Selecting P or N when idling at a stand-
still for prolonged periods of time will
help prevent overheating of the auto-
matic transmission fluid.
3If the gear selector is in the D or R positions and the car is not moving, engine speed (rpm) will be lower and it will take longer for the engine to reach normal operating temperature.

259
Driving through water
•The vehicle can be driven through water up
to a depth of approximately 10 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 10 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
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.
Engine and cooling systemUnder special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.
•Maintain a low speed when driving with a
trailer up long, steep hills.
•Do not turn the engine off immediately
when stopping after a hard drive.
WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.
•Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.
•Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:
•When the engine is not running, avoid
using ignition mode II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.
•Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained. Driving or having the
engine running for approximately
15 minutes will help keep the battery
charged.

06 During your trip
Refueling
06

265
Opening/closing the fuel cap
G022915
Fuel vapor expands in hot weather. Open the
filler cap slowly.
After refueling, close the fuel filler cap by turn-
ing it clockwise until it clicks into place.
CAUTION
•Do not refuel with the engine running2.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge.
•Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much fuel
in the tank in hot weather conditions can
cause the fuel to overflow. Overfilling
could also cause damage to the emis-
sion control systems.
Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will helpavoid malfunctions that could damage the
three-way catalytic converter.
•Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•Remember that tampering or unauthorized
modifications to the engine, the Engine
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission system
components or location or removing com-
ponents, and/or repeated use of leaded
fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
2If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.

WARNING
•Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Use only tires with the
correct load carrying capacity. Consult
your Volvo retailer for information.
