2004 VOLVO XC70
The stability systems consist of a number of functions:
The following two functions are common to both STC/DSTC
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 car (on the s\
ame 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 STC/DSTC's permanent functions and is not affected wh\
en the 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 car is
accelerating. This is done by temporarily reducing engine torque to the \
drive wheels, which helps
improve stability and tractive force.
Under certain circumstances, such as when driving with snow chains, or d\
riving in deep snow or loose
sand, it may be advisable to temporarily switch off this function for ma\
ximum tractive force. This is
done by pressing the STC/DSTC button on the center control panel for at \
least a half a second.
When the SC function has been switched off:
l The text window (see page 27) will briefly display "SPIN CONTROL OFF"
l The LED in the STC/DSTC button will be off.
The following two functions are only available with DSTC:
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 car shows a tendency to skid or slide laterally. Th\
is is done by activating the Anti-
lock Braking System. A pulsating sound will be audible when the function\
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.
R-models only:
The AYC function can be deactivated. This is done by pressing the DSTC b\
utton on the center control
panel (see the illustration on
page 31) for approximately one second. This procedure must be repeated 5
times, after which "DSTC REDUCED FUNCTION" will be displayed in the text\
window. AYC will be

automatically reactivated the next time the ignition is switched on. WARNING!
With AYC disabled, the car's handling and stability characteristics will\
be altered.
4. 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.
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.
pg. 21 STC/DSTC
Maintain full pressure on the brake pedal in order to utilize the system\
completely. EBA is automatically
deactivated when the brake pedal is released. When the car has been park\
ed for some time, the brake
pedal may sink more than usual when the engine is started. This is norma\
l and the pedal will return to its
usual position when it is released.
The STC/DSTC button
The STC/DSTC button in the center control panel (see page 31) is used to switch the Spin Control (SC)
function on or off
NOTE: AYC (on models equipped with this function) will also be reduced, but\
not switched off, if SC
is switched off.
The button must be pressed for at least a half second to prevent SC from\
being switched off
inadvertently.
When the function has been switched off, the green indicator lamp in the\
button will go out and "STC/
DSTC SPIN CONTROL OFF" will be displayed in the text window.
All STC/DSTC functions are (re)activated each time the engine is start\
ed.

1. Driving distance on current fuel reserve
This function shows the approximate distance that can be driven on the f\
uel remaining in the tank. This
calculation is based on average fuel consumption during the last 12 mile\
s (20 km) of driving and the amount
of fuel remaining in the tank when the reading was taken. When the drivi\
ng distance on current fuel reserve is
less than 12 miles (20 km), "----" will be displayed in the text windo\
w.
2. Average fuel consumption

Cold weather precautions
If you wish to check your car before the approach of cold weather, the f\
ollowing 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 car's radia\
tor. Your local Volvo
retailer stocks plenty of Volvo engine coolant to protect your car durin\
g 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 this cold-weather oil for hard driving or in warm weather. See secti\
on "Engine 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 anti-rust oil on the batter\
y 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
page 136 for the location of the washer fluid reservoir). This is important sin\
ce dirt is often splashed on
the windshield during winter driving, requiring the frequent use of the \
washers and wipers. The Volvo
Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water \
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water \
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
W Winter/Wet driving mode - enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive posit\
ion.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode.
l An LED in the button will light up to indicate that W is engaged and this will also be displayed in the
instrument panel (see
page 27).
l This mode may be selected for starting/moving off on slippery roads.
