Dstc - Stability And Traction Control System - Volvo C30 Owner's Manual

General
The stability and traction control system, STC/
DSTC (Dynamic Stability and Traction Control)
helps the driver to avoid skidding and improves
the car's traction.
A pulsing sound may be noticed during braking
or acceleration when the system is in action.
The car may accelerate slower than expected
when the accelerator pedal is depressed.
The car is equipped with either STC or DSTC
depending on market. The table shows the
integral functions of the respective systems.

Active Yaw Control
The function limits the driving and brake force
of the wheels individually in order to stabilise
the car.
1 No function in cars without trip computer, fuel-driven parking heater as well as stability and traction control system.
Spin Control
The function prevents the driving wheels from
spinning against the road surface during accel-
eration.
Traction control system
The function is active at low speed and trans-
fers power from the driving wheel that is spin-
ning to the one that is not.

06 Starting and driving
The stability system is activated automatically
each time the car is started.
System operation during skidding and accel-
eration can be partially deactivated. Operation
during skidding is then delayed and so allows
more skidding which provides greater freedom
for dynamic driving. Traction in deep snow or
sand is improved at the same time as acceler-
ation is no longer limited.
Operation
1. Turn thumbwheel until the STC/DSTC
menu is shown.
DSTC ON means that the system function
is unchanged.
DSTC SPIN CONTROL OFF
system operation is reduced.
2. Press and hold the RESET button until the
STC/DSTC menu is changed.
The system remains reduced until the
driver reactivates it or until the engine is
switched off - after the engine is started the
next time DSTC is back in its normal mode
again.
