The driving mode, RWD or AWD, is shown

on the instrument cluster display.

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)

System

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.

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 counter the vehicle’s

understeer or oversteer.

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.

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.

Traction Control System (TCS)

The system automatically operates in the

event of slipping, loss of grip on wet

roads (hydroplaning), and acceleration on

one or both drive wheels on roads that

are slippery, snowy, icy, etc. Depending

on the slipping conditions, two different

control systems are activated:

If the slipping involves both drive

wheels, the system intervenes, reducing

the power transmitted by the engine.

If the slipping only involves one of the

drive wheels, the Brake Limited

Differential (BLD) function is activated,

automatically braking the wheel which is

slipping (the behavior of a self-locking

differential is simulated). This will

increase the engine torque transferred to

the wheel which isn't slipping.
