EPB (Electronic Parking Brake)
may be automatically applied
when:
Requested by other systems
The driver turns the engine off
while Auto Hold is operating.
Warning messages

tened and the engine hood or lift-
gate is opened, a warning will
sound and a message will appear.
If there is a problem with the vehi-
cle, a warning may sound and a
message may appear.
If the situation occurs, depress the
brake pedal and release EPB by
pressing the EPB switch.
OTMA058132
Whenever leaving the vehicle
or parking, always come to a
complete stop and continue
to depress the brake pedal.
Move the shift lever into the P
(Park) position, press the EPB
switch, and set the ignition
switch to the OFF position.
Take the Key with you when
exiting the vehicle.
Vehicles not fully engaged in
P (Park) with the parking
brake set are at risk for mov-
ing inadvertently and causing
injury to yourself or others.
NEVER allow anyone who is
unfamiliar with the vehicle to
touch the EPB switch. If the
EPB is released unintentional-
ly, serious injury may occur.

Do not apply the accelerator
pedal while the parking brake is
engaged. If you depress the
accelerator pedal with the EPB
engaged, a warning will sound
and a message will appear.
Damage to the parking brake
may occur.
Driving with the parking brake
on can overheat the braking sys-
tem and cause premature wear
or damage to brake parts. Make
sure the EPB is released and the
Parking Brake Warning Light is
off before driving.
Information
• A clicking sound may be heard
while operating or releasing the
EPB. These conditions are normal
and indicate that the EPB is func-
tioning properly.
• When leaving your keys with a
parking attendant or assistant,
make sure to inform him/her how
to operate the EPB.
AUTO HOLD turning Off!
Press brake pedal
When the conversion from Auto Hold
to EPB is not working properly a
warning will sound and a message
will appear.

Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti-
freeze as these may damage the
paint finish.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear selector lever in P
and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

Maintenance
Fuse switch
Always, place the fuse switch to the
ON position.
If you move the switch to the OFF
position, some items such as the
audio system and digital clock must
be reset and the smart key may not
work properly.
Information
If the fuse switch is OFF, the above
message will appear.
Always place the fuse switch inthe ON position while driving the
vehicle.
Do not move the fuse switch repeatedly. The fuse switch may
be damaged.
Engine Compartment Panel
Fuse Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover by pressing the tap and pulling up.
4. Check the removed fuse; replace it if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
5. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature
difference between the lamp inside
and outside and, it does not indicate a
problem with your vehicle. When
moisture condenses in the lamp, it will
be removed after driving with the
headlamp on. The removable level
may differ depending on lamp size,
lamp position and environmental con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
HYUNDAI dealer.
Information - Desiccant
(if equipped)
This vehicle is equipped with desic-
cant to reduce fogging inside the head-
lamp due to moisture.
The desiccant is consumable and its
performance may change based on the
used period or environment.
If fogging inside the headlamp due to
moisture continues for a long time,
have your vehicle checked by an
authorized HYUNDAI dealer. i
i
Prior to replacing a lamp,
depress the brake pedal,
move the shift lever into P
(Park) apply the parking
brake, place the igntion
switch to the LOCK/OFF posi-
tion, and take the key with you
when leaving the vehicle to
avoid sudden movement of
the vehicle and to prevent
possible electric shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Maintenance
Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric’s appearance and
fire-resistant properties.
Leather (if equipped)
Feature of Seat Leather
- Leather is made from the outerskin of an animal, which goes
through a special process to be
available for use. Since it is a nat-
ural object, each part differs in
thickness or density. Wrinkles
may appear as a natural result of
stretching and shrinking depend-
ing on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
product.
NOTICE
Wrinkles or abrasions which
appear naturally from usage
are not covered by warranty.
Belts with metallic acces-
sories, zippers or keys inside
the back pocket may damage
the seat fabric.
Make sure not to wet the seat.
It may change the nature of
natural leather.
Jeans or clothes which could
bleach may contaminate the
surface of the seat covering
fabric.
