How does the air bag system
operate?
The SRS consists of the following
components:
(1) Driver's front air bag module/
Driver’s knee air bag module
(2) Passenger's front air bag module
(3) Side air bag modules/
Side impact sensors
(4) Curtain air bag modules
(5) Retractor pre-tensioner assem-
blies
(6) Air bag warning light
(7) SRS control module (SRSCM)
(8) Front impact sensors
(9) Side pressure sensorsThe SRSCM continually monitors all
SRS components whilst the ignition
switch is ON to determine if a crash
impact is severe enough to require
air bag deployment or pre-tensioner
seat belt deployment.
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration. The
system checks the air bag electrical
system for malfunctions. The light indi-
cates that there is a potential problem
with your air bag system.OPD037063AU
If your SRS malfunctions, the
air bag may not inflate properly
during an accident increasing
the risk of serious injury or
death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating for approximately six
seconds.
The light comes on whilst the
vehicle is in motion.
The light blinks when the
engine is running.
We recommend that an autho-
rised HYUNDAI dealer inspect
the SRS as soon as possible if
any of these conditions occur.

Convenient features of your vehicle
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
once to indicate the system is
armed.Once the security system is set, open-
ing any door, the tailgate, or the bon-
net without using the remote key or
smart key will cause the alarm to acti-
vate.
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
System does not operate nor-
mally, the warning light ( ) will
illuminate or blink on the instru-
ment cluster. The steering wheel
may become difficult to control
or operate. We recommend that
you take your vehicle to an
authorised HYUNDAI dealer and
have the system checked as
soon as possible.
When abnormality is detected in
the electric power steering sys-
tem, to prevent a deadly acci-
dent, the steering assist function
will stop. At this time, the warn-
ing light turns on or blinks on
the cluster. The steering wheel
may become difficult to control
or operate. Have your vehicle
checked immediately, after mov-
ing the vehicle to a safe zone.
Information
The following symptoms may occur
during normal vehicle operation:
• The steering effort may be high
immediately after placing the igni-
tion switch button in the ON posi-
tion.
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 in the ON or LOCK/OFF
position.
• 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, abnor-
mal noise may occur. If the temper-
ature rises, the noise will disappear.
This is a normal condition.

Remote window closing
function (if equipped)
You can still control the window
movement with the engine turned off
by pressing the door lock button (1)
for more than 3 seconds. The window
moves (up), as long as you press the
door lock button. The window move-
ment stops, when you release the
door lock button. The hazard warning
lights blink 3 times, when the window
is completely closed.
Information
• The remote window closing function
may abruptly stop, when you move
away from your vehicle during the
operation. Stay in close proximity of
your vehicle, whilst monitoring the
window movement.
• One of the windows may stop oper-
ating, when the window is interrupt-
ed by certain force. However, the
other windows will keep operating.
Thus, you should make sure that all
windows are closed, and that the
hazard warning lights blink 3 times.
i
NEVER leave the keys in your
vehicle with unsupervised
children, when the engine is
running.
NEVER leave any child unat-
tended in the vehicle. Even
very young children may inad-
vertently cause the vehicle to
move, entangle themselves in
the windows, or otherwise
injure themselves or others.
Always double check to make
sure arms, hands, head and
other obstructions are safely
out of the way before closing
a window.
Do not allow children to play
with the power windows. Keep
the driver’s door power window
lock switch in the LOCK posi-
tion (pressed). Serious injury
can result from unintentional
window operation by the child.
Do not extend your head,
arms or body outside the win-
dows whilst driving.

3. Lower the bonnet halfway (lifted
approximately 30cm from the
closed position) and push down to
securely lock in place. Then double
check to be sure the bonnet is
secure.
If the bonnet can be raised slightly, it
is not securely locked. Open it again
and close it with more force.

latched before driving away.
Check there is no bonnet open
warning light or message dis-
played on the instrument clus-
ter. If the bonnet is not latched
whilst the vehicle is moving,
the chime will sound to warn
the driver the bonnet is not
fully latched. Driving with the
bonnet opened may cause a
total loss of visibility, which
might result in an accident.
Do not move the vehicle with
the bonnet in the raised posi-
tion, as vision is obstructed,
which might result in an acci-
dent, and the bonnet could fall
or be damaged.

working, more than normal pedal
travel and greater pedal pressure are
required to stop the vehicle.Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail whilst you are driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.
