Stability system
04``155 Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
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.Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, 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.
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 maxi-
mum tractive force.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.Operation

mately 1 mph (1.6 km/h).
NOTE
•
A temporary increase in speed by
pressing the accelerator pedal, for less
than 1 minute (e.g. when passing
another car), does not affect the current
cruise control setting. The vehicle will
automatically return to the previously
set speed when the accelerator pedal is
released.
•
If one of the cruise control buttons is
kept depressed for more than approx.
1 minute cruise control is disengaged.
The engine must then be switched off in
order to reset cruise control.
Automatic deactivationCruise control is automatically deactivated
temporarily if one of the following occurs:•
If the speed drops below approximately
20 mph (30 km/h).
•
When the brake pedal is depressed.
•
If the gear selector is moved to position N.
•
During wheel spin or wheel lock-up.
•
If the vehicle's speed is increased by using
the accelerator pedal for more than 1
minute.
The currently set speed will be saved in the
system's memory.

Adaptive cruise control cannot be engaged
at speeds below 20 mph (30 km/h).
The “car” symbol illuminates
on the left side of the display
when the radar sensor
detects another vehicle
ahead. The distance to a vehi-
cle ahead is only regulated
when this symbol is illumi-
nated.
Adjusting the set speedAfter a speed has been set, it can be increased
or decreased by using the
or
buttons.
When the system is in active mode, the
but-
ton has the same function as

a smaller increase in speed.
NOTE
•
If one of the adaptive cruise control but-
tons is pressed for more than approxi-
mately one minute, ACC will be deacti-
vated. The engine must then be
switched off and restarted to reset ACC.

In some situations cruise control cannot
be activated.

Setting a time intervalThe set time interval to vehicles ahead is
increased with
and decreased with
.
The current time interval is shown briefly in the
display following adjustment.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval. At low
speeds, when the distance to
the vehicle ahead is short, ACC increases the
time interval slightly. In order to follow the vehi-
cle ahead as smoothly as possible, ACC allows
the time interval to vary considerably in certain
situations.
