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 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 thumbwheel (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.
NOTE
• The message DSTC SPIN CONTROL
OFF indicates that the stability system's
spin control function has temporarily
been switched off.
• The stability control indicator light will
illuminate and remain on until spin control
has been reactivated.
• The spin control function is automatically
enabled each time the engine is
started.
• DSTC ON indicates that all system
functions are active.
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.
This is one of DSTC's permanent functions and cannot be switched off.
WARNING
The car's handling and stability characteristics
will be altered if the DSTC system functions
have been disabled.
