Refueling
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 weari\
ng-in to each other. From the time
the engine is new until the first maintenance is performed, the oil cons\
umption could be higher than
normal. For this reason, it is especially important to check the oil eve\
ry time you refuel your vehicle
during this period. See
page 142.
Fuel requirements
Octane rating
Volvo engines are designed for optimum performance on unleaded premium g\
asoline with an AKI
octane rating of 91 or above. AKI (ANTI KNOCK INDEX) is an average of \
the Research Octane
Number, RON, and the Motor Octane Number, MON. ((RON + MON)/2). The \
minimum octane
requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposit\
s. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use o\
f deposit control gasolines will
help ensure good driveability and fuel economy. If you are not sure whet\
her the gasoline contains
deposit control additives, check with the service station operator.
NOTE: Volvo does not recommend the use of external fuel injector cleaning syst\
ems.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleade\
d gasoline. U.S. and Canadian
regulations require that pumps delivering unleaded gasoline be labelled \
"UNLEADED". Only these
pumps have nozzles which fit your vehicle's filler inlet. It is unlawful\
to dispense leaded fuel into a
vehicle labelled "unleaded gasoline only". Leaded gasoline damages the t\
hree-way catalytic converter
and the heated oxygen sensor system. Repeated use of leaded gasoline wil\
l lessen the effectiveness of
the emission control system and could result in loss of emission warrant\
y coverage. State and local
vehicle inspection programs will make detection of misfueling easier, po\
ssibly resulting in emission test
failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine Light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
maintenance.

affect the fuel pump's ability to supply the engine with an adequate sup\
ply of fuel. Therefore, it is
advisable to refuel as soon as possible when the needle nears the red zo\
ne, or when the fuel warning
light comes on.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may
cause a spark that could ignite gasoline fumes, resulting in fire and in\
jury.
CAUTION
- Do not refuel with the engine running *. Turn the ignition off or to p\
osition I. If the ignition is on,
an incorrect reading could occur in the fuel gauge
- After refueling, close the fuel filler cap by turning it clockwise unt\
il it clicks into place*.
- Allow for fuel expansion by not overfilling the tank. Overfilling coul\
d also cause damage to the
emission control systems.
- Avoid spilling gasoline during refueling. In addition to causing damag\
e to the environment,
gasolines containing alcohol can cause damage to painted surfaces, which\
may not be covered under
the New Vehicle Limited Warranty.
- Do not use gasolines containing methanol (methyl alcohol, wood alcoho\
l). This practice can result
in vehicle performance deterioration and can damage critical parts in th\
e fuel system. Such damage
may not be covered under the New Vehicle Limited Warranty.
* If the fuel filler cap is not closed tightly or if the engine is runni\
ng 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 fu\
el filler caps.

General information
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid\
starts and stops and
adjusting the speed of your vehicle to immediate traffic conditions. Obs\
erve the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on
the accelerator pedal for the first few minutes of operation. A cold eng\
ine uses more fuel and is subject
to increased wear.
l Whenever possible, avoid using the vehicle for driving short distances. \
This does not allow the engine
to reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Use the transmission's (D)rive position as often as possible and avoid using "kickdown" to help
improve fuel economy.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the vehicle.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc, increase air resistance and also f\
uel consumption.
l At highway driving speeds, fuel consumption will be lower with the air c\
onditioning on and the
windows closed than with the air conditioning off and the windows open. \
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard\
Maintenance intervals.
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.

2005 VOLVO XC90
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. To avoid
such a delay when the brakes are needed, depress the pedal occasionally \
when driving through rain,
slush, etc. This will remove the water from the brakes. Check that brake\
application feels normal. This
should also be done after washing or starting in very damp or cold weath\
er.
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 o\
f the brakes is less efficient than
when driving on level roads. To reduce the strain on the brakes, shift i\
nto a lower gear and let the engine
help with the braking. Do not forget that if you are towing a trailer, t\
he brakes will be subjected to a
greater than normal load.

Brake system (contd)
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 Volv\
o retailer for inspection. The
Anti-lock Braking System (ABS) helps to improve vehicle control (stop\
ping and steering) during severe
braking conditions by limiting brake lockup. When the system "senses" im\
pending lockup, braking
pressure is automatically modulated in order to help prevent lockup, whi\
ch could lead to a skid.
This system performs a self-diagnostic test when the engine is started a\
nd 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 from 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 potentia\
l of the vehicle. While control
will be enhanced, ABS will not shorten stopping distances on slippery su\
rfaces.
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 duri\
ng braking, which is normal.

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 140 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

Dynamic Stability Traction Control (DSTC) (contd)
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" will be displayed in the text window. If this occurs, stop the\
vehicle in a suitable place,
switch off and restart the engine. If the light remains on, an authorize\
d 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 again when the brakes have coole\
d.
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.

To attach the towing eyelet:
A Use a coin to pry open the lower edge of the cover (A).
B Screw the towing eyelet (C) in place (B), first by hand and then us\
ing the tire iron until it is securely
in place.
After the vehicle has been towed, the eyelet should be removed and retur\
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 104).
- 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.
