Air bag inflation conditions
Front air bags
Front air bags are designed to inflate in a frontal collision depending on the intensi-
ty, speed or angles of impact of the frontcollision.
1JBA3513/H
(Continued)
Problems may arise if the sensor
installation angles are changed
due to the deformation of the
front bumper, body or B and C pil-
lars where side collision sensors
are installed. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.
Your vehicle has been designed to absorb impact and deploy the
air bag(s) in certain collisions.
Installing bumper guards or
replacing a bumper with non-gen-
uine parts may adversely affect
your vehicle’s collision and air
bag deployment performance.WARNING
Do not hit or allow any objects to impact the locations where air
bags or sensors are installed.
This may cause unexpected air
bag deployment, which could
result in serious personal injuryor death.
If the installation location or angle of the sensors is altered in
any way, the air bags may deploy
when they should not or they may
not deploy when they should,
causing severe injury or death.
Therefore, do not try to perform
maintenance on or around the air
bag sensors. Have the vehicle
checked and repaired by an
authorised HYUNDAI dealer.

Smart key precautions
✽✽
NOTICE
 If, for some reason, you happen to lose your smart key, you will not be able to
start the engine. Tow the vehicle, if
necessary, and contact an authorised
HYUNDAI dealer.
 A maximum of 2 smart keys can be
registered to a single vehicle. If you
lose a smart key, you should immedi-
ately take the vehicle and key to your
authorised HYUNDAI dealer to pro-
tect it from potential theft.

Features of your vehicle
Air bag warning light(if equipped)
This warning light will illuminate for
approximately 6 seconds each time you
turn the ignition switch to the ON posi-tion. This light also comes on when the
Supplemental Restraint System (SRS) is
not working properly. If the SRS air bag
warning light does not come on, or
continuously remains on after operating
for about 6 seconds when you turned the
ignition switch to the ON position or start-
ed the engine, or if it comes on whilst
driving, have the SRS inspected by an
authorised HYUNDAI dealer.
Anti-lock brake system
(ABS) warning light (if equipped)
This light illuminates if the ignition switch
is turned ON and goes off in approxi-
mately 3 seconds if the system is operat-
ing normally.
If the ABS warning light remains on,
comes on whilst driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that there may be a malfunction with the
ABS.
If this occurs, have your vehicle checked
by an authorised HYUNDAI dealer as
soon as possible. The normal braking
system will still be operational, but with-
out the assistance of the anti-lock brakesystem. Electronic brake
force distribution
(EBD) system
warning light
If two warning lights illuminate at the
same time whilst driving, your vehicle
may have a malfunction with the ABSand EBD system.
In this case, your ABS and regular brake
system may not work normally. Have the
vehicle checked by an authorised
HYUNDAI dealer as soon as possible.
✽✽
NOTICE
If the ABS warning light or EBD warn-
ing light is on and stays on, the
speedometer or odometer/tripmeter
may not work. In this case, have your
vehicle checked by an authorised
HYUNDAI dealer as soon as possible.
WARNING
If the both ABS and brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally during sudden braking. In
this case, avoid high speed driving
and abrupt braking. Have your vehi-
cle checked by an authorised
HYUNDAI dealer as soon as possi-
ble.

Non-operational conditions of rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.
8. Trailer towing The detecting range may decrease when:
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter. Rear parking assist system pre- cautions
The rear parking assist system may
not sound sequentially depending on the speed and shapes of the objectsdetected.
The rear parking assist system may malfunction if the vehicle bumperheight or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.

Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ONposition.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released whilst
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution whilst operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop. Anti-lock brake system (ABS) (if equipped)
W-75
(Continued)
On roads where the road surface
is pitted or has different surface height.
The safety features of an ABS (or
ESP) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.
WARNING
ABS (or ESP) will not prevent acci-
dents due to improper or danger-
ous driving manoeuvres. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for cars
equipped with an anti-lock braking
system (or Electronic Stability
Program system) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle should be driven at reducedspeeds:
Rough, gravel or snow-covered roads.
With tyre chains installed. (Continued)

Driving your vehicle
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.✽✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
Even with the anti-lock brake system, your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev- er, your regular brakes will worknormally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. During that time, the ABS will go throughself-diagnosis and the light will gooff if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorised HYUNDAI dealer as soon as possible.

✽✽
NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
Electronic stability program (ESP) (if equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize the vehicle
during cornering manoeuvres. ESP
checks where you are steering and where
the vehicle is actually going.
ESP applies the brakes at individual
wheels and intervenes in the engine
management system to stabilize the
vehicle.
CAUTION
When you drive on a road having
poor traction, such as an icy road,
and operate your brakes continu-ously, the ABS will be active con-tinuously and the ABS warning light may illuminate. Pull your car
over to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then your
ABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorised HYUNDAI dealer as
soon as possible.WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability program
(ESP) will not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres and hydroplaning onwet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding manoeuvres that
cause the vehicle to lose traction.
Even with ESP installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.
