Dstc - Stability And Traction Control System - Volvo V70 Owner's Manual

General information on DSTC
The stability and traction control system, DSTC
(Dynamic Stability and Traction Control) helps
the driver to avoid skidding and improves the
car's traction.
The system limits the driving and brake force
of the wheels individually so that skidding can
be avoided. This increases manoeuvrability
and as a result safety in the event of sudden
movement.
Traction is improved by means of the system
distributing the driving force between the
wheels. The system primarily engages at low
speed on poor road surfaces.
The activation of the system during braking
may be noticed as a throbbing sound. The car
may accelerate slower than expected when the
accelerator pedal is depressed.
Messages in the information display
DSTC Temporarily OFF
System temporarily reduced due to excessive
brake disc temperature. The function is reacti-
vated automatically when the brakes have
cooled.
DSTC Service required
System disabled due to a fault.
Stop the car in a safe place and turn off the
engine. If the message remains when the
engine is restarted, drive to an authorised
Volvo workshop.
Symbols in the combined instrument
panel
If the symbols and
at the same time, read the message on the
information display.
If the symbol appears alone then it may
appear as follows:
•
Flashing light means that the system is
now being activated.
•
Constant glow for 2 seconds means sys-
tem check when the engine is started.
•
Constant glow after starting the engine or
while driving means system fault.
Reduced operation
System operation during skidding and accel-
eration can be reduced. Operation during skid-
ding is delayed and so allows more skidding
which provides greater freedom for dynamic
driving. Traction in deep snow or sand is
improved as traction is no longer limited.
