Active Torque Vectoring (ATV) — If Equipped
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axles. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
Given that, in a turn, the external wheels of the
car travel more than the internal ones and
therefore turn faster, sending a higher thrust
to the external rear wheel allows for the car to
be more stable and to not suffer an "under-
steer" condition. Understeer occurs when the
vehicle is turning less than appropriate for the
steering wheel position.
Dynamic Steering Torque (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 contribu-
tion 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.

Drive Train Control (DTC) System — If
Equipped
Some models of this vehicle are equipped with
an All-Wheel Drive (AWD) system, which offers
an optimal drive for countless driving condi -
tions and road surfaces. The system reduces
the slipping of the tires to a minimum, auto -
matically 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 environ -
mental 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.
Electronic Stability Control (ESC)
The ESC system improves the directional
control and stability of the vehicle in various
driving conditions.
The ESC system corrects the vehicle’s under -
steer 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.

How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal circuits
and interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC posi -
tion, the air bag system is not on and the air
bags will not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch
is first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of
the system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single
chime will sound to alert you if the light comes on
again after initial startup.

The ORC also includes diagnostics that will illu -
minate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While
the air bag system is designed to be mainte - WARNING!
The seat belt assembly must be replaced
if the switchable Automatic Locking
Retractor (ALR) feature or any other seat
belt function is not working properly when
checked according to the procedures in
the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in colli-
sions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.
