Stability System - Volvo S60 Owner's Manual

The EBA function is designed to provide full brake effect immediately in the event of sudden, hard braking. The
system is activated by the speed with which you depress the brake pedal.
NOTE
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically deactivated when the brake
pedal is released.
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.

Stability system

Dynamic Stability Traction Control (DSTC)
The stability system consists of a number of functions designed help reduce wheel spin, counteract skidding, and to
generally help improve directional stability.
NOTE
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)
This function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose
traction to the wheel on the opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of the DSTC's permanent functions and cannot be switched off.
Spin control (SC)
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily switch off this function for maximum tractive force.
Temporarily switching off Spin control
1. Turn the thumb wheel (1) on the left-side steering wheel lever until the DSTC menu is displayed.
2. Hold down the RESET button (2) to toggle between DSTC SPIN CONTROL ON or OFF.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.)
WARNING
The car's handling and stability characteristics will be altered if the DSTC system functions have been disabled.
