Indicator and warning lights
The indicator and warning lights described on pages 28 and 29 should never stay on when driving*
When the ignition key is turned, all of the warning lights in the lower
right-hand side of the instrument panel should go on to test the function
of the bulbs. If a light does not go off after the engine has started, thesystem indicated should be inspected.
NOTE: The parking brake reminder light will not go off until the
parking brake has been fully released.
Warning lamp in the
center of the instrument
panel
This lamp lights up red or yellow depending
on the severity of the fault that has been
detected.
Red symbol - Stop the vehicle as soon as
possible in a suitable location and read the
message shown in the text window. The
symbol and accompanying text will remain on
until the fault has been corrected.
Yellow symbol - Follow the instructions
shown in the text window. The text can be

Speed-sensitive power steering
(Option on certain models)
With this feature, the steering is most responsive at lower speeds to
make parking, driving in city traffic, etc., easier. The effect of the power
steering diminishes as you accelerate for greater stability at highway
speeds.

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 immedi-
ate traffic conditions. Observe the following rules:

Anti-lock Brake System (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 retailer for inspection.
The Anti-lock Braking System (ABS) helps to improve vehicle control
(stopping and steering) during severe braking conditions by limiting
brake lockup. When the system "senses" impending lockup, braking
pressure is automatically 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
and 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 be kept on the brake pedal. Do not pump the brake pedal.
The switching of the ABS modulator will be audible and the brake pedal
will pulsate during braking. Please be aware that ABS does not increase
the absolute braking potential of the vehicle. While 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, 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.

to switch between preset stations.
Scan
Press the SCAN button to start the station scan
function. When a station is found, scanning
stops for approximately 10 seconds, after
which scanning will continue.
Press the SCAN or SOURCE button when a
station has been found if you would like to
listen to that station and to discontinue the
scan function.
Station seek up/down
Press or to start the seek function. The
radio seeks the next audible station and tunes
it in. Repeat the procedure to continue the seek
function.

Manual station search
Press or and hold it down. MAN will
be shown in the display. The radio scans
slowly in the selected direction and will
increase the scanning speed after a few
seconds. Release the button when the desired
frequency appears in the display.
The frequency can be fine-tuned by short
presses on the
or keys.
The system will remain in manual search
mode for 5 seconds after the button is released,
after which it will return to seek mode.V70/XC70 V70 R3902452d3905086m
