conditions which may lock the wheels,  
you may hear sounds from the brakes,  
or feel a corresponding sensation in  
the brake pedal. This is normal and it  
means your ESC is active.

automatically disengages. The Cruise  
Control can be reengaged when the  
road conditions allow. See “Cruise  
Control System” later in this chapter  
7 (if equipped).  
The Electronic Stability Control (ESC)  
system helps to stabilize the vehicle  
during cornering manoeuvres.  
ESC checks where you are steering and  
where the vehicle is actually going.  
ESC applies braking pressure to any one  
of the vehicle’s brakes and intervenes in  
the engine management system to assist  
the driver with keeping the vehicle on  
the intended path. It is not a substitute  
for safe driving practices. Always adjust  
your speed and driving to the road  
conditions.  
WARNING  
śꢀ :KHQꢀPRYLQJꢀRXWꢀRIꢀWKHꢀPXGꢀRUꢀ  
driving on a slippery road, the engine  
RPM (revolutions per minute) may  
not increase even if you press the  
accelerator pedal deeply. This is to  
maintain the stability and traction of  
the vehicle and does not indicate a  
problem.  
Never drive too fast for the road  
conditions or too quickly when  
cornering. The ESC system will not  
prevent accidents.  
Excessive speed in turns, abrupt  
manoeuvres, and hydroplaning on wet  
surfaces can result in severe accidents.

„ESC OFF indicator light (comes on)  
Press the ESC OFF button briefly. The  
ESC OFF indicator light and/or message  
‘Traction Control disabled’ will illuminate  
and a warning chime sounds. In this  
state, the traction control function of  
ESC (engine management) is disabled,  
but the brake control function of ESC  
(braking management) still operates.  
When the ignition switch is in the  
ON position, the ESC indicator light  
illuminates, then goes off if the ESC  
system is operating normally.  
The ESC indicator light blinks whenever  
the ESC is operating.  
If the ESC indicator light stays on, your  
vehicle may have a malfunction with  
the ESC system. When this warning  
light illuminates we recommend that  
the vehicle be checked by a HYUNDAI  
authorised repairer as soon as possible.  
The ESC OFF indicator light comes on  
when the ESC is turned off with the  
button.

Press and hold the ESC OFF button  
continuously for more than 3 seconds.  
The ESC OFF indicator light and/or  
message ‘Traction control and ESC  
disabled’ illuminates and a warning  
chime sounds. In this state, both the  
traction control function of ESC (engine  
management) and the brake control  
function of ESC (braking management)  
are disabled.  
If the ignition switch is placed in the  
LOCK/OFF position when ESC is off, ESC  
remains off. Upon restarting the vehicle,  
the ESC will automatically turn on again.  
WARNING  
When the ESC is blinking, this indicates  
the ESC is active:  
Drive slowly and NEVER attempt to  
accelerate. NEVER turn the ESC off  
whilst the ESC indicator light is blinking  
or you may lose control of the vehicle  
resulting in an accident.  
NOTICE  
Driving with wheels and tyres with  
different sizes may cause the ESC  
system to malfunction. Before  
replacing tyres, make sure all four tyres  
and wheels are the same size. Never  
drive the vehicle with different sized  
wheels and tyres installed.
