For your convenience, we have
incorporated tabs on the right-hand
page edges. These tabs are coded
with the Chapter titles to assist you
with navigating through the manual. Your safety, and the safety of others,
is very important. This Owner's
Manual provides you with many safe-
ty precautions and operating proce-
dures. This information alerts you to
potential hazards that may hurt you
or others, as well as damage to your
vehicle.
Safety messages found on vehicle
labels and in this manual describe
these hazards and what to do to
avoid or reduce the risks.
Warnings and instructions contained
in this manual are for your safety.
Failure to follow safety warnings and
instructions can lead to serious injury
or death.
Throughout this manual DANGER,
WARNING, CAUTION, NOTICE and
the SAFETY ALERT SYMBOL will
be used.
This is the safety alert sym-bol. It is used to alert you to
potential physical injury haz-
ards. Obey all safety mes-

Why Didn't My Air Bag Go Off
in a Collision?
Air bags are not designed to inflate in
every collision.There are certain
types of accidents in which the air bag
would not be expected to provide
additional protection. These include
rear impacts, second or third colli-
sions in multiple impact accidents, as
well as low speed impacts. Damage
to the vehicle indicates a collision
energy absorption, and is not an indi-
cator of whether or not an air bag
should have inflated.
Air bag collision sensors
NEVER place a rear-facing or
front-facing child restraint in
the front passenger's seat of
the vehicle.
An inflating frontal air bag
could forcefully strike a child
resulting in serious injury or
death.
Always properly restrain chil-
dren in an appropriate child
restraint in the rear seat of the
vehicle.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and
causing serious injury or death:
Do not hit or allow any objects
to impact the locations where air
bags or sensors are installed.
(Continued)
WARNING
(Continued)
Do not perform maintenance
on or around the air bag sen-
sors. If the location or angle of
the sensors is altered, the air
bags may deploy when they
should not or may not deploy
when they should.
Do not install bumper guards
or replace the bumper with a
non-genuine HYUNDAI parts.
This may adversely affect the
collision and air bag deploy-
ment performance.
Place the Engine Start/Stop
button in the OFF or ACC
position when the vehicle is
being towed to prevent inad-
vertent air bag deployment.
Have all air bag repairs conduct-
ed by an authorized HYUNDAI
dealer.

2-68
Safety system of your vehicle
Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehi-
cle structure.
SRS Care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the Engine Start/Stop but-
ton is in the ON position, or continu-
ously remains on, have your vehicle
immediately inspected by an author-
ized HYUNDAI dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel, the
front passenger's panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury. To reduce the risk of serious
injury or death, take the follow-
ing precautions:
Do not attempt to modify or
disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger's panel above the glove
box.
Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-
tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.

Also, the vehicle will not stop in as
short a distance with only a portion
of the brake system working.
If the brakes fail while 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.Regenerative BrakeWarning Light
This warning light illuminates :
When you place the Engine Start/
Stop button to the ON position.
- It illuminates for approximately 3seconds.
When the regenerative brake does not operate and the brake does not
perform well. This causes the Brake

Brake Warning Light to illuminate
simultaneously.
In this case, drive safely and have
your vehicle inspected by an author-
ized HYUNDAI dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase.

Detecting range may decrease when:
Outside air temperature is extreme-ly hot or cold.
Undetectable objects smaller than 40 inches (1 m) and narrower than
6 inches (14 cm) in diameter.
The following objects may not be
recognized by the sensor:
Sharp or slim objects such asropes, chains or small poles.
Objects, which tend to absorb sen- sor frequency such as clothes,
spongy material or snow.
Rear parking assist system pre-cautions
The rear parking assist system
may not operate consistently in
some circumstances depending on
the speed of the vehicle and the
shapes of the objects detected.
The rear parking assist system may malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
The sensor may not recognize objects less than 15 in. (40 cm)
from the sensor, or it may sense an
incorrect distance. Use caution.
When the sensor is blocked with snow, dirt, debris, or ice, the rear
parking assist system may be inop-
erative until the snow or ice melts,
or the debris is removed. Use a
soft cloth to wipe debris away from
the sensor.
Do not push, scratch or strike the sensor with any hard objects that
could damage the surface of the
sensor. Sensor damage could occur. Do not spray the sensors or its sur-
rounding area directly with a high
pressure washer. Doing so may
cause the sensors to fail to operate
normally.
Convenient features of your vehicle
Your new vehicle warranty does
not cover any accidents or dam-
age to the vehicle or injuries to
its occupants related to a Rear
Parking Assist System. Always
drive safely and cautiously.

Driving your vehicle
Do not depress the brake pedal
continuously without the " "
indicator ON. The battery may be
discharged.
Some noise and vibration may occur during braking. This is
normal.
In below cases, some electric brake pump noise and motor
vibration may occur temporarily.
This is normal operation.
- When the pedal is depressedvery quickly
- When the pedal is depressed multiple times in short inter-
vals
- When the ABS function is acti- vated during braking
Disc Brake Wear Indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Parking Brake
Always set the parking brake before
leaving the vehicle. To apply the
parking brake:
Firmly depress the brake pedal.
Depress the parking brake pedal
down as far as possible.
