(DST)
DST uses the integration of the Electronic
Stability Control (ESC) system with the electric
power steering to increase the safety level of the
whole vehicle.
In critical situations (braking on surfaces with
different grip conditions), the ESC system
controls the steering through the DST function to
implement an additional torque contribution on
the steering wheel in order to suggest the most
correct maneuver to the driver.
The coordinated action of the brakes and
steering increases the sensation of safety and
control of the vehicle.
NOTE:
The DST feature is only meant to help the driver
realize the correct course of action through small
torques on the steering wheel, which means the
effectiveness of the DST feature is highly depen
-
dent on the driver’s sensitivity and overall reac
-
tion to the applied torque. It is very important to
realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering
the vehicle.

QUIPPED
Some models of this vehicle are equipped with an
All-Wheel Drive (AWD) system, which offers an
optimal drive for countless driving conditions and
road surfaces. The system reduces the slipping of
the tires to a minimum, automatically
redistributing the torque to the front and rear
wheels as needed.
To maximize fuel savings, the vehicle with AWD
automatically passes to Rear-Wheel Drive (RWD)
when the road and environmental conditions are
such that they wouldn't cause the tires to slip.
When the road and environmental conditions
require better traction, the vehicle automatically
goes to AWD mode.
NOTE:
If the system failure symbol switches on, after
starting the engine or while driving, it means that
the AWD system is not working properly. If the
warning message activates frequently, it is
recommended to carry out the maintenance
operations.

ONTROL
(ESC)
The ESC system improves the directional control
and stability of the vehicle in various driving
conditions.
The ESC system corrects the vehicle’s understeer
and oversteer, distributing the brake force on the
appropriate wheels. The torque supplied by the
engine can also be reduced in order to maintain
control of the vehicle.
Oversteer
occurs when the vehicle is turning
more than it should according to the angle of
the steering wheel.
Understeer
occurs when the vehicle is turning
less than it should according to the angle of
the steering wheel.
The ESC system uses sensors installed on the
vehicle to determine the path that the driver
intends to follow and compares it with the
vehicle’s effective path. When the real path
deviates from the desired path, the ESC system
intervenes to counteract the above conditions.
System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The
capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.
