This system helps to protect your
vehicle and valuables. The horn will
sound and the hazard warning lights
will blink continuously if any of the
following occur:
- A door is opened without using the
remote key or smart key.
- The tailgate is opened without
using the remote key or smart key.
- The engine bonnet is opened.
The alarm continues for 30 seconds,
then the system resets. To turn off
the alarm, unlock the doors with the
remote key or smart key.
The Theft Alarm System automati-
cally sets 30 seconds after you lock
the doors and the tailgate. For the
system to activate, you must lock the
doors and the tailgate from outside
the vehicle with the remote key or
smart key or by pressing the button
on the outside of the door handles
with the smart key in your posses-
sion.
The hazard warning lights will blink
and the chime will sound once to
indicate the system is armed.Once the security system is set,
opening any door, the tailgate, or the
bonnet without using the remote key
or smart key will cause the alarm to
activate.
The Theft Alarm System will not set if
the bonnet, the tailgate, or any door
is not fully closed. If the system will
not set, check the bonnet, the tail-
gate, or the doors are fully closed.
Do not attempt to alter this system or
add other devices to it.
Information
• Do not lock the doors until all pas-
sengers have left the vehicle. If the
remaining passenger leaves the
vehicle when the system is armed,
the alarm will be activated.
• If the vehicle is not disarmed with
the remote key or smart key, open
the doors by using the mechanical
key and place the ignition switch in
the ON position (for remote key) or
start the engine (for smart key) and
wait for 30 seconds.
• When the system is disarmed but a
door or tailgate is not opened within
30 seconds, the system will be
rearmed.

Electric power steering (EPS)
The system assists you with steering
the vehicle. If the engine is off or if
the power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Also, the steering effort becomes
heavier as the vehicle’s speed
increases and becomes lighter as
the vehicle’s speed decreases for
better control of the steering wheel.
Should you notice any change in the
effort required to steer during normal
vehicle operation, we recommend
that the system be checked by an
authorised HYUNDAI dealer.If the Electric Power Steering
(EPS) System does not operate
normally, the warning light ( )
will illuminate on the instrument
cluster. The steering wheel may
become difficult to control or
operate. Take your vehicle to an
authorised HYUNDAI dealer and
have the system checked as soon
as possible.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch or the Engine Start/Stop
button in the ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering wheel will return to
its normal condition.• A click noise may be heard from the
EPS relay after the ignition switch is
placed to the ON or LOCK/OFF
position (Without Smart key sys-
tem).
A click noise may be heard from the
EPS relay after the Engine
Start/Stop button is placed in the
ON or OFF position. (With Smart
key system)
• Motor noise may be heard when the
vehicle is at a stop or at a low driv-
ing speed.
• When you operate the steering
wheel in low temperatures, the
steering effort may be high and
abnormal noise may occur. If the
temperature rises, the noise will dis-
appear. This is a normal condition.
• When the vehicle is stationary, if
you turn the steering wheel all the
way to the left or right continuously,
the steering wheel effort increases.
This is not a system malfunction. As
time passes, the steering wheel
effort will return to its normal con-
dition.
