03 Your driving environment
Instruments and controls
03``75
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 – SLOW DOWN
" to
"
HIGH ENGINE TEMP – STOP ENGINE
." If
appropriate, other messages, such as
"
COOLANT LEVEL LOW
" will also be dis-
played. 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.
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 219. If the level in the reservoir is below
MIN, the vehicle should be transported to an
authorized Volvo workshop to have the brake
system checked.
Canadian models are equipped with this sym-
bol: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 219. 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 comes on when a fault
has been indicated which could affect the
safety and/or drivability of the vehicle. An
explanatory text is shown on the information
display at the same time. The symbol remains
visible until the fault has been rectified but the
text message can be cleared with the READ
button, see page 121. 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.Reminder – doors not closedIf one of the doors, the hood or tailgate is not
closed properly, the information or warning
symbol comes on together with an explanatory
text message in the instrument panel. Stop the
vehicle in a safe place as soon as possible and
close the door, hood or tailgate.
If the vehicle is driven at a speed
lower than approximately 5 mph
(7 km/h), the information symbol comes on.

WARNING
•
Always remove the remote key from the
ignition slot when leaving the vehicle,
especially if there are children in the
vehicle.
•
Never remove the remote key from the
ignition slot while driving or when the
vehicle is being towed. The steering
lock could otherwise be activated, mak-
ing it impossible to steer the vehicle.
Never remove the remote key with key-
less drive function (option) 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
•
The idling speed can be noticeably
higher than normal during cold starts.
This is to enable emission control sys-
tem can reach normal operating tem-
perature as quickly as possible, which
helps reduce exhaust emissions
3.
•
Keylock: Your vehicle is equipped with
a keylock system. When the engine is
switched off, the gear selector must be
in the Park position before the key can
be removed
4 from the ignition slot.
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.
•
SelectingP or N when idling at a stand-
still for prolonged periods of time will
help prevent overheating of the auto-
matic transmission fluid.
Keyless drive (option)Follow steps 3 – 4 for starting the engine.
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.4Does not apply to vehicles with the optional keyless drive.

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.
•
The optional 12 volt socket in the cargo
area provides electrical current even with
the ignition switched off, which drains the
battery.

05 During your trip
Refueling
05
201
CAUTION
•
Do not refuel with the engine running
1.
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. Overfill-
ing could also cause damage to the
emission control systems.
Emission controlsThree-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.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.
1If 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.

05 During your tripTowing a trailer
05210
IntroductionVolvo recommends the use of Volvo trailer
hitches that are specially designed for the vehi-
cle.
NOTE
See page 271 for the maximum trailer and
tongue weights recommended by Volvo.•
Observe the legal requirements of the
state/province in which the vehicles are
•
All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.
Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•
Increase tire pressure to recommended
full. See the tire inflation tables on pages
248 and 249.
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
Maximum speed when towing a trailer:
50 mph (80 km/h).
•
Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watchedwhen driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•
If the automatic transmission begins to
overheat, a message will be displayed in
the text window.
•
Avoid overload and other abusive opera-
tion.
•
Hauling a trailer affects handling, durabil-
ity, and economy.
•
It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball and drawbar assembly
when the hitch is not being used.
•
Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.
WARNING
•
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•
Trailer hitches attaching to the vehicle
rear axle must not be used.
•
Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult your nearest author-
ized Volvo retailer for correct installa-
tion.
•
When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.
