wheel VOLVO XC90 2003 Owner's Manual

2003 VOLVO XC90
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, \
which means that the steering
wheel has to be turned more than might seem appropriate for the curvatur\
e of a bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these p\
roperties can alter with the
vehicle load. The heavier the load in the cargo area, the less the tende\
ncy to understeer.
WARNING!
Driving with the tailgate open: Driving with the tailgate open could lead to poisonous exhaust gases
entering the passenger compartment. If the tailgate must be kept open fo\
r any reason, proceed as
follows
- Close the windows
- Set the ventilation system control to air flow to floor, windshield an\
d side windows and blower
control to its highest setting.
CAUTION
Drive slowly and carefully if going through standing water (i.e. floode\
d roadways, etc.). Damage to
the engine could result if excess water is drawn in through the air inta\
ke system. Never drive the
vehicle in water deeper than 18 inches (48 cm).

General information (contd)
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore, check that the tires
are inflated to the recommended pressure according to the vehicle load. \
See "Tire pressure" section.
Loads should be distributed so that capacity weight or maximum permissib\
le axle loads are not exceeded.
Driving on rough/unpaved surfaces
The Volvo XC90 is designed primarily for onroad driving, and it has exce\
llent 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.

All Wheel Drive
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 norma\
l driving conditions, most of
the engine's power is directed to the front wheels. However, if there is\
any tendency for the front wheels

2003 VOLVO XC90
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. N\
ever drive on mixed tires, except
for brief periods when the temporary spare tire is in use. Always use pr\
operly inflated tires of correct
dimensions. Tire size and inflation pressures are shown on the tire pres\
sure label located inside the fuel
filler door.
Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tir\
es should be rotated front-to-
back/back-to-front only. Tires must maintain the same direction of rotat\
ion throughout their lifetime, and
should never be rotated from one side of the vehicle to the other.
Temporary Spare
The temporary spare tire is for temporary, lowspeed, short-distance use \
only. Replace it with a full-sized
tire as soon as possible, in accordance with "Tire Rotation" in the prev\
ious paragraph. Do not drive on
the temporary spare at speeds above 50 m.p.h. (80km/h) or for distance\
s greater than 50 miles (80 km).
Never install snow chains on a temporary spare.

If the BRAKE and ABS warning lights come on at the same time, this could\
indicate a fault in the brake
system.
l Stop the vehicle in a suitable place and switch off the engine.
l Restart the engine.
l If both warning lights go off, no further action is required.
l If both lights are still on after the engine has been restarted, switch \
off the engine again and check the
brake fluid level (see
page 128 for the location of the brake fluid reservoir).
l If the brake fluid level is above the MIN mark, drive carefully to an au\
thorized Volvo retailer and
have the brake system inspected.
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
retailer and have the brake system inspected.

Dynamic Stability Traction Control (DSTC)
The DSTC system on the Volvo XC90 consists of a number of functions:
1. Traction control (TC)
This function is designed to help reduce wheel spin by transferring powe\
r from a drive wheel that begins
to lose traction to the wheel on the opposite side of the vehicle (on t\
he same axle). TC monitors and
compares the rotational speed of the drive wheels. If one of the drive w\
heels shows a tendency to spin,
the difference in speed is immediately detected. This triggers the Anti-\
lock Brake System, which brakes
the spinning wheel until the difference in rotational speed is corrected\
.
TC is most active at low speeds, and a pulsating sound will be audible w\
hen the system is regulating
wheel spin. This is quite normal.
This is one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.
2. Spin control (SC)
The spin control function is designed to help prevent the drive wheels f\
rom spinning while the vehicle is
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps

improve tractive force. Under certain circumstances, such as when drivin\
g with snow chains, or driving
in deep snow or loose sand, it may be advisable to temporarily switch of\
f this function for maximum
tractive force. This is done by pressing the DSTC button on the center c\
ontrol panel for at least a half a
second.
When the SC function has been switched off:
l The text window will briefly display "DSTC SPIN CONTROL OFF"
l The LED in the DSTC button will be off.
3. Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cor\
nering, by braking one or more
of the wheels if the vehicle shows a tendency to skid or slide laterally\
. This is done by activating the
Anti-lock Braking System. A pulsating sound will be audible when the fun\
ction is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is also one of the DSTC system's permanent functions and is not aff\
ected when the DSTC button on
the center control panel is pressed.
4. Roll Stability Control (RSC)
RSC utilizes a gyro-sensor to monitor the vehicle's angle of inclination\
, and the rate at which this angle
changes. If necessary, RSC activates the Anti-lock Brake System to brake\
one or more of the wheels to
help maintain stability. A pulsating sound will be audible when the func\
tion is active, which is quite
normal. If you apply the brakes while this function is active, the brake\
pedal will feel stiffer than usual.
This is one of the DSTC system's permanent functions and is not affected\
when the DSTC button on the
center control panel is pressed.
pg. 98 Starting and driving
Dynamic Stability Traction Control (DSTC) (contd)
The DSTC button
The DSTC button in the center control panel is used to switch the Spin C\
ontrol (SC) function on or off.
The button must be pressed for at least a half second to prevent SC from\
being switched off
inadvertently.
When the system has been switched off, the green indicator lamp in the b\
utton will go out and "DSTC
SPIN CONTROL OFF" will be displayed in the text window.

All DSTC functions are (re)activated each time the engine is started.
The Stability Control indicator light
The Stability Control indicator light will come on for approximately 2 s\
econds when the ignition is
switched on as the system performs a self-diagnostic test.
The Stability Control indicator light will flash when:
l Traction Control is actively functioning to help avoid drive-wheel spin.\

l Spin Control is actively functioning to help avoid loss of traction duri\
ng acceleration.
l Active Yaw Control is actively functioning to help avoid skids or latera\
l slides.
l Roll Stability Control is actively functioning to help avoid a roll-over\
situation.
The warning symbol in the instrument panel
A steady yellow glow indicates:
l That the system has been automatically disengaged due to a fault. "ANTI \
SKID SERVICE
REQUIRED" be displayed in the text window. An authorized Volvo retailer \
should check the system.
l In the event of high brake temperature, "TRACTION CONTROL TEMPORARILY OF\
F" will be
displayed in the text window. The system will automatically switch on ag\
ain when the brakes have
cooled.
Emergency Brake Assistance (EBA)
The EBA function is an integrated part of the DSTC system. EBA is design\
ed to provide full brake
effect immediately in the event of sudden, hard braking. The system is a\
ctivated 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. Maintain full pressure on th\
e brake pedal in order to utilize
the system completely. EBA is automatically deactivated when the brake p\
edal 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. This is normal and the pedal will return to its usual\
position when it is released.

ned to the tool bag. Press the
cover back into position.
Precautions when the vehicle is in tow
l The steering wheel must be unlocked. Turn the ignition key to position I\
or II.
l The gear selector must be in position N.
l Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable t\
owing speed.
l Maximum distance with front wheels on ground: 50 miles (80 km).
l While the vehicle is being towed, try to keep the tow rope taut at all t\
imes.
l The vehicle should only be towed in forward direction.
CAUTION
- Please check with state and local authorities before attempting this t\
ype of towing, as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
- If the vehicle's battery is dead, do not attempt to start the vehicle \
by pushing or pulling it as this will
damage the three-way catalytic converter(s). The engine must be jump s\
tarted using an auxiliary
battery (see
page 102).
- If the vehicle is being towed on a flat bed truck, the towing eyelets \
must not be used to secure the
vehicle on the flat bed. Consult the tow truck operator.
WARNING!
- Remember that the power brakes and power steering will not function wh\
en engine is not running.
The braking and steering systems will function but the brake pedal press\
ure required is 3 - 4 times
above normal and greater steering effort must be exerted.
- The towing eyelets must not be used for pulling the vehicle out of a d\
itch or for any similar purpose
involving severe strain. Do not use the towing eyelets to pull the vehic\
le up onto a flat bed tow truck.

Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equipment.
If wheel lift equipment must be used, please use extreme caution to help\
avoid damage to the vehicle. In
this case, the vehicle should be towed with the rear wheels on the groun\
d if at all possible.
If it is absolutely necessary to tow the vehicle with the front wheels o\
n the ground, please refer to the
towing information on the previous page. CAUTION
Sling-type equipment applied at the front will damage radiator and air c\
onditioning lines.
It is equally important not to use sling-type equipment at the rear or a\
pply lifting equipment inside the
rear wheels; serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets mu\
st not be used to secure the
vehicle on the flat bed. Consult the tow truck operator.
WARNING!
Do not use the towing eyelets to pull the vehicle up onto a flat bed tow\

truck.

Towing a trailer
Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l Maximum trailer weights recommended by Volvo are:
All models - trailers without brakes: 1,650 lbs (750 kg)
Models with all wheel drive - trailers with brakes: 4,960 lbs (2250 kg)\

Models with front wheel drive - trailers with brakes: 3,970 lbs (1800 k\
g)
Observe the legal requirements of the state/province in which the vehicl\
es are registered.
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 bump\
er system.
Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Recommended hitch tongue load is: Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 198 lbs (90 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
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 Avoid overload and other abusive operation.
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 More frequent vehicle maintenance is required.
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.

pg. 107 Starting and driving
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her 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 by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo
retailer stocks plenty of Volvo engine coolant to help protect your vehi\
cle during cold weather.
l 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 f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming up. For winter use,
5W-30 oil, particularly the synthetic type*, is recommended. Be sure to \
use good quality oil but do not
use cold-weather oil for hard driving or in warm weather. See section "E\
ngine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
.
are used more often. Moreover, the capacity of the battery decreases as \
the temperature drops. In very
cold weather, a poorly charged battery can freeze and be damaged. It is \
therefore advisable to check the
state of charge more frequently and spray an antirust oil on the battery\
posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels
and tires."
l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see
