Maintenance
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 main-
tain its luster. Removing oil, tar, and
similar materials with a spot remover
will usually strip the wax from the fin-
ish. Be sure to re-wax these areas
even if the rest of the vehicle does
not yet need waxing.
Wet brakes
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.
WARNING
•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 liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
CAUTION
•Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
•Do not use steel wool, abra-
sive cleaners, or strong deter-
gents containing highly alka-
line or caustic agents on
chrome-plated or anodized
aluminum parts. This may
result in damage to the protec-
tive coating and cause discol-
oration or paint deterioration.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation 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 vehi-
cle, 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.

Maintenance
•Do not operate the engine in con-
fined 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.
Operating precautions for cat-
alytic converters (if equipped)
Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-
ing.
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 dry grass, paper,
leaves, etc.
•The exhaust system and cat-
alytic system are very hot
while the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, 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.
WARNING

Yo u r v e h i c l e i s e q u i p p e d w i t h a c a t -
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
•Use only UNLEADED FUEL for
gasoline engine.
•Do not operate the vehicle when
there are signs of engine mal-
function, 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.
(Continued)
(Continued)
•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 emis-
sion control system. All inspec-
tions and adjustments must be
made by an authorized
HYUNDAI dealer.
•Avoid driving with a very low
fuel level. If you run out of
gasoline, it could cause the
engine to misfire and result in
excessive loading of the cat-
alytic converter.

Specifications & Consumer information*1:Refer to the recommended SAE viscosity numbers on the next page.
*2:Engine oils labeled Energy Conserving Oil are now available.Along with other additional benefits, they contribute to fuel economy by reducingthe amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’stime, they can offer significant cost and energy savings.
*3:If the ACEA A5 engine oil is not available in your country, you are able to use ILSAC GF-4 (or above) or API SM (or above).
*4:If the API service SM engine oil is not available in your country, you are able to use API service SL.
