brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward
speed.

NOTICE
• Water washing in the engine
compartment including high pressure
water washing may cause the failure
of electrical circuits located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle
(if equipped)
Automatic car wash which uses
rotating brushes should not be used
as this can damage the surface of your
vehicle. A steam cleaner which washes
the vehicle surface at high temperature
may result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber towel
or sponge) when washing your vehicle
and dry with a microfiber towel. When
you hand wash your vehicle, you should
not use a cleaner that finishes with
wax. If the vehicle surface is too dirty
(sand, dirt, dust, contaminant, etc.),
clean the surface with water before
washing the car.
Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to maintain
its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.

Maintenance
Bright-metal maintenance
• To remove road tar and insects, use
a tar remover, not a scraper or other
sharp object.
• To protect the surfaces of bright-metal
parts from corrosion, apply a coating
of wax or chrome preservative and rub
to a high luster.
• During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, accelerated
rusting can occur on the underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with rust
protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm
or cold water once a month, after off-
road driving and at the end of each
winter. Pay special attention to these
areas because it is difficult to see all
the mud and dirt. It will do more harm
than good to wet down the road grime
without removing it. The lower edges
of the doors, rocker panels, and frame
members have drain holes that should
not clog with dirt; trapped water in these
areas can cause rusting.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward
speed.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
• Do not use any abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
• Clean the wheel when it has cooled.
• Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, be sure to clean the
wheels after driving on salted roads.
This helps prevent corrosion.
• Avoid washing the wheels with high-
speed car wash brushes.
• Do not use any alkaline or acid
detergent. It may damage and corrode
the aluminum wheels coated with a
clear protective finish.

3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
• This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate
governmental safety and emissions
regulations.
In addition, damage or performance
problems resulting from any
modification may not be covered
under warranty.
• If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present with
other exhaust fumes. Therefore, if
you smell exhaust fumes of any kind
inside your vehicle, have it inspected
and repaired immediately. If you ever
suspect exhaust fumes are coming
into your vehicle, drive it only with
all the windows fully open. Have
your vehicle checked and repaired
immediately.
WARNING
Exhaust
Engine exhaust gases contain carbon
monoxide (CO). Though colorless
and odorless, it is dangerous and
could be lethal if inhaled. Follow the
instructions on this page to avoid CO
poisoning.
• Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
• When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with the
engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system.

Maintenance
Operating precautions for catalytic
converters (if equipped)
WARNING
Fire
• A hot exhaust system can ignite
flammable items under your vehicle.
Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc.
• The exhaust system and catalytic
system are very hot while the engine
is running or immediately after the
engine is turned off. Keep away from
the exhaust system and catalytic, you
may get burned. Also, do not remove
the heat sink around the exhaust
system, do not seal the bottom of the
vehicle or do not coat the vehicle for
corrosion control. It may present a
fire risk under certain conditions.Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for petrol
engine.
• Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
• Do not misuse or abuse the engine.
Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.
• Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
• Do not modify or tamper with any
part of the engine or emission
control system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
• Avoid driving with a extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
catalytic converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
