Generator warning light
If the light comes on while the engine is running, have the charging sys\
tem checked.
Rear fog light
This light indicates that the fog light is on.
CHECK ENGINE Malfunction indicator light
On-Board Diagnostics II (OBDII): As you drive, a computer called "OBDI\
I" monitors your vehicle's
engine, transmission, electrical and emission systems. The CHECK ENGINE \
light will light up if the
computer senses a condition that potentially may need correcting. When t\
his happens, please have your
vehicle checked by a Volvo retailer as soon as possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice\
a change in your
vehicle's behavior. Even so, an uncorrected condition could hurt fuel ec\
onomy, emission cleanliness, and
driveability. Extended driving without correcting the cause could even d\
amage other components in
your vehicle.
Canadian models are equipped with this warning light.

General information
Engine oil
Although some oil consumption occurs during normal engine operation, mor\
e oil is consumed when the engine is new as
the internal parts generate higher friction while wearing-in to each oth\
er. From the time the engine is new until the first
maintenance is performed, the oil consumption could be higher than norma\
l. For this reason, it is especially important to
check the oil every time you refuel your vehicle during this period. See\

page 187.

Octane rating
Volvo engines are designed to achieve rated horsepower, torque, and fuel\
economy performance using premium 91 octane
fuel. Volvo recommends premium for best performance, but using 87 octane\
or above will not affect engine reliability.
In demanding driving conditions, such as operating the vehicle in hot we\
ather, towing a trailer, or driving for extended
periods at higher altitudes than normal, it may be advisable to switch t\
o higher octane fuel (91 or higher) or to change
gasoline brands to fully utilize your engine's capacity, and for the smo\
othest possible operation.
NOTE: When switching to higher octane fuel or changing gasoline brands, it ma\
y be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not \
use lead additives. Besides damaging the exhaust
emission control systems on your vehicle, lead has been strongly linked \
to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been stron\
gly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions.\
These may include:
l standing upwind away from the filler nozzle while refueling
l refueling only at gas stations with vapor recovery systems that fully se\
al the mouth of the filler neck during refueling
l wearing neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not a\
dd solvents, thickeners, or other store-bought
additives to your vehicle's fuel, cooling, or lubricating systems. Overu\
se may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expo\
se yourself to these chemicals.

Difficult driving conditions
Driving on rough/unpaved surfaces
The Volvo XC90 is designed primarily for on-road driving, and it has exc\
ellent handling characteristics on very rough or
unpaved roads.
When driving on poorly maintained or unpaved roads, please keep the foll\
owing in mind:
l Reduce speed on rough surfaces to minimize possible damage to the vehicl\
e's underbody.
l When driving on soft surfaces such as dry sand or snow, try to avoid sto\
pping if at all possible.
WARNING!
Avoid driving diagonally across steep inclines as this could increase th\
e risk of a roll-over. Try to drive straight up or
down the slope.
If the road is very steep, avoid turning the vehicle around to help avoi\
d the risk of rolling over. Back the vehicle up or
down the incline instead.
NOTE: Avoid driving on steep inclines if the fuel tank is nearly empty. If th\
e flow of fuel to the engine is interrupted due
to the vehicle's angle of inclination, this could result in damage to th\
e three-way catalytic converter. We recommend
keeping the fuel tank at least half full when driving on steep inclines.\
Driving through water
The vehicle can be driven through water up to a depth of approximately 1\
8 inches (48 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 wa\
ter.
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!
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 18 in (48 cm), wate\
r may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorte\
n the service life of these components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This could result in
electrical malfunctions.
l 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.

BRAKE Brake circuit malfunction
The brake system is a hydraulic system consisting of two master cylinder\
s and two separate brake circuits. If a problem
should occur in one of these circuits, it is still possible to stop the \
vehicle with the other brake circuit.
If the brake pedal must be depressed farther than normal and requires gr\
eater foot pressure, the stopping distance will be
longer.
A warning light in the instrument panel will light up to warn the driver\
that a fault has occurred.
If this light comes on while driving or braking, stop immediately and ch\
eck the brake fluid level in the reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not \
pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent" message is displayed in
the text window: DO NOT DRIVE. Have the vehicle towed to a Volvo retaile\
r and have the brake system inspected.
NOTE: When the vehicle is at a standstill and the engine is idling, e.g. at a\
traffic light and the brake pedal is depressed,
the pedal may go down slightly. This is a normal function of the power-a\
ssisted brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let the vehicle roll to a
stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder than usual to make
up for the lack of power assistance. This can happen for example when to\
wing your vehicle or if the engine is switched off
when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can c\
ause water to collect on the brake discs and pads.
This will cause a delay in braking effect when the pedal is depressed. T\
o avoid such a delay when the brakes are needed,
depress the pedal occasionally when driving through rain, slush etc. Thi\
s will remove the water from the brakes. Check
that brake application feels normal. This should also be done after wash\
ing or starting in very damp or cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess efficient than when driving on level roads. To
reduce the strain on the brakes, shift into a lower gear and let the eng\
ine help with the braking. Do not forget that, if you
are towing a trailer, the brakes will be subjected to a greater than nor\
mal load.
pg. 128 Starting and driving
Brake system
Anti-lock brakes (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will however
function) and the vehicle should be driven cautiously to a Volvo retail\
er for inspection. The Anti-lock Braking System
(ABS) helps to improve vehicle control (stopping and steering) durin\
g severe braking conditions by limiting brake lockup.

l At a distance of approximately 1 foot (30 cm), the signal will become \
constant. If objects are close to both the front and
rear bumpers, the signal will alternate between the front and rear speak\
ers.
Deactivating the system(s)
- Press the Park assist button on the center console (see
page 52) to temporarily deactivate the system(s).
- The indicator light in the button will go out when the system(s) hav\
e been deactivated.
- If the vehicle is equipped with front and rear park assist, both syste\
ms will be deactivated by pressing the button.
Park assist will be automatically reactivated the next time the engine i\
s started.
NOTE: It may be necessary to deactivate one or both of the park assist system\
s in certain cases.
l Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, co\
uld trigger the rear park assist
system's sensors.
l Front park assist: it may not be possible to combine auxiliary headlights and front park \
assist since these lights could
trigger the system's sensors.
pg. 133 Starting and driving
Front/rear park assist (accessory/option)
Faults in the system
If the yellow warning symbol illuminates and a message is shown in the i\
nformation display, the system is not
functioning properly. Consult a Volvo retailer or authorized service tec\
hnician.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rea\
r bumpers should be kept clean. They can be cleaned
with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the ve\
hicle. They are not, however, intended to
replace the driver's attention and judgement.
CAUTION!
In certain circumstances, the park assist system may give unexpected war\
ning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. Th\
is may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhau\
st pipes, etc. This does not indicate a fault in
the system.

Towing a trailer
The maximum weights recommended by Volvo for trailers with brakes are shown in the table below.
NOTE:
l Recommended hitch tongue load: not more than 10% of the trailer's weight\
. The trailer load should be positioned
so that it does not shift and the tongue load should be 10% of the trail\
er's weight. However, the tongue load should not
exceed the maximum permissible weights indicated in the table above.
l When towing trailers without brakes, the maximum permissible trailer weight is 1,700 lbs (750 kg).\

l If necessary, redistribute the weight of any cargo in the trailer to avo\
id excessive weight on the trailer hitch.
l The maximum trailer weight listed in the table for All Wheel Drive model\
s, 5,000 lbs (2250 kg) is only applicable when
there are not more than two occupants in the vehicle, in the front seats\
, with a combined weight of 300 lbs (135 kg), with
no other cargo in the vehicle.
l The maximum weight listed for Front Wheel Drive models, 4,000 lbs (1800\
kg) is only applicable when there are not
more than four occupants in the vehicle, in the front seats and second r\
ow of seats, with a combined weight of 600 lbs (270
kg), with no other cargo in the vehicle.
pg. 138 Starting and driving
Towing a trailer
l Please be aware that the load on the trailer hitch is part of the vehicl\
e's total load carrying capacity. The amount of cargo
in the vehicle and the trailer must be limited so that the gross vehicle\
weight and maximum permissible rear axle weight
(see
page 209) are not exceeded.
l Vehicles used for towing a trailer on a regular basis, or for long-dista\
nce highway towing should be equipped with an
automatic transmission oil cooler and Volvo's automatic self-leveling sy\
stem for the rear suspension. Consult your Volvo
retailer.
l Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
l Increase tire pressure to recommended full inflation pressure. See chapt\
er "Wheels and tires."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should be closely

watched when driving in hot climates or hilly terrain. Use a lower gear \
and turn off the air conditioner if the temperature
gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check and observe state/
local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in mountainous areas.
NOTE:
l When parking the vehicle with a trailer on a hill, apply the parking bra\
ke before putting the gear selector in (P)ark.
When starting on a hill, put the gear selector in (D)rive before relea\
sing the parking brake. Always follow the trailer
manufacturer's recommendations for wheel chocking.
l If you use the manual (Geartronic) shift positions while towing a trai\
ler, make sure the gear you select does not put too
much strain on the engine (using too high a gear).
WARNING!
l Bumper-attached trailer hitches must not be used on Volvos, nor should s\
afety chains be attached to the bumper.
l Trailer hitches attaching to the vehicle rear axle must not be used.
l 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 authorized\
Volvo retailer for correct installation.
l When towing a trailer, the trailer's safety wire must be correctly faste\
ned to the hole or hook provided in the trailer
hitch on the vehicle. The safety wire should never be fastened to or wou\
nd around the drawbar ball.

Towing a trailer
Smoother starts with a trailer
Models equipped with the V8-engine and the 6-speed automatic transmissio\
n have a built-in function that reduces
acceleration slightly in first gear when the vehicle is towing a trailer\
. This is done to help avoid wheel spin and to make
starting off smoother.
l This function is activated when the trailer's electrical connector is pl\
ugged into the electrical socket mounted near the
trailer hitch.
l The function is automatically deactivated when the trailer's wiring is d\
isconnected from the socket. The vehicle will
then accelerate normally.
NOTE: Since this function is activated when a connector is plugged into the e\
lectrical socket near the trailer hitch, it will
be activated by any electrical equipment (e.g. bicycle racks with light\
ing, etc) that is plugged in, and will remain active
until the equipment is unplugged from the socket.
Leveling
If your vehicle is equipped with automatic leveling, the rear suspension\
always retains the correct ride height regardless of
the load.
l The system adjusts the rear suspension to the correct level after the ve\
hicle has been driven a short distance.
