All Wheel Drive (option)
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is distributed
automatically between the front and rear wheels. Under normal driving co\
nditions, most of the engine's power is directed
to the front wheels. However, if there is any tendency for the front whe\
els to spin, an electronically controlled coupling
distributes power to the wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread pattern, load-,
speed-, traction- , temperature-, and treadwear rating. Never drive on m\
ixed tires, except for brief periods when the
temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on the tire inflation
pressure placards, located on the driver's side B-pillar (the structura\
l member at the side of the vehicle, at the rear of the
driver's door opening), or on the inside of the fuel filler door on Can\
adian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-sized tire as soon as
possible. Do not drive on the temporary spare at speeds above 50 m.p.h. \
(80km/h) or for distances greater than 50 miles
(80 km).
Never install snow chains on a temporary spare.

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.

2007 Volvo XC90
When the system "senses" impending lockup, braking pressure is automatic\
ally modulated in order to help prevent lockup,
which could lead to a skid.

The system performs a self-diagnostic test when the engine is started an\
d when the vehicle first reaches a speed of
approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible f\
rom the ABS
control module. This is normal.

To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake pedal. Do not pump the
brake pedal.

The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate during braking. Please be aware that
ABS does not increase the absolute braking potential of the vehicle. Whi\
le control will be enhanced, ABS will not shorten
stopping distances on slippery surfaces.
ABS with EBD (Electronic Brake Force Distribution)
EBD is an integrated part of the ABS system. EBD regulates the hydraulic\
pressure to the rear brakes to help provide
optimal braking capacity. The brake pedal will pulsate during braking, w\
hich is normal.
If the BRAKE and ABS warning lights come on at the same time, this could\
indicate a fault in the brake system.
- Stop the vehicle in a suitable place and switch off the engine.
- Restart the engine.
- If both warning lights go off, no further action is required.
- If both lights are still on after the engine has been restarted, switc\
h off the engine again and check the brake fluid level
(see
page 185 for the location of the brake fluid reservoir).
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.
- If the brake fluid level is above the MIN mark, drive carefully to an \
authorized Volvo retailer and have the brake system
inspected.
Emergency Brake Assistance (EBA)
The EBA function is designed to provide full brake effect immediately in\
the event of sudden, hard braking. The system is
activated by the speed with which you depress the brake pedal.
NOTE:
l When the EBA system is activated, the brake pedal will go down and press\
ure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the b\
rake pedal in order
pg. 129 Starting and driving
Brake system
to utilize the system completely. There will be no braking effect if the\
pedal is released. EBA is automatically deactivated
when the brake pedal is released.
l When the vehicle has been parked for some time, the brake pedal may sink\
more than usual when the engine is started.

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.

Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer\
before driving long distances. Your retailer will
also be able to supply you with bulbs, fuses, spark plugs and wiper blad\
es for your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check transmission oil level1.
l Check condition of drive belts.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legally required in some states/provinc\
es.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to obtain the correct
fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to occur, consider snow
tires.
1. To prevent injury from contact with hot surfaces, do not inspect your\
vehicle's transmission fluid yourself. Have your vehicle's
transmission fluid level inspected by a qualified Volvo service technici\
an.

WARNING!
The traction grade assigned to this tire is based on braking (straight-\
ahead) traction tests and is not a
measure of cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing\
the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under c\
ontrolled conditions on a specified
indoor laboratory test wheel. Sustained high temperature can cause the m\
aterial of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire \
failure. The grade C corresponds
to a minimum level of performance that all passenger vehicle tires must \
meet under the Federal Motor
Safety Standard No. 109. Grades B and A represent higher levels of perfo\
rmance on the laboratory test
wheel than the minimum required by law.
WARNING!
The temperature grade for this tire is established for a tire that is pr\
operly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading, either separatel\
y or in combination, can cause
heat buildup and tire failure.
pg. 164 Wheels and tires
Snow chains, snow tires, studded tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
l Snow chains should be installed on front wheels only. Use only Volvo app\
roved snow chains.
l If accessory, aftermarket or "custom" tires and wheels are installed and\
are of a size different than the
original tires and wheels, chains in some cases CANNOT be used. Sufficie\
nt clearances between chains
and brakes, suspension and body components must be maintained.
l Some strap-on type chains will interfere with brake components and there\
fore CANNOT be used.
l All Wheel Drive models: Snow chains should only be installed on the fron\
t wheels. Only chains
adapted for AWD models should be used.
Consult your Volvo retailer for additional snow chain information.
