Cleaning the upholstery and interior
trim
Vinyl
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl surfaces with a vinyl cleaner.
Fabric
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean with a mild soap solution recom-
mended for upholstery or carpets.
Remove fresh spots immediately 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
properly maintained.
Cleaning the lap/shoulder belt web-bing
Clean the belt webbing with any mild
soap solution recommended for cleaning
upholstery or carpet. Follow the instruc-
tions provided with the soap. Do not
bleach or re-dye the webbing because
this may weaken it.
Cleaning the interior window glass
If the interior glass surfaces of the vehi-
cle become fogged (that is, covered with
an oily, greasy or waxy film), they should
be cleaned with glass cleaner. Follow the
directions on the glass cleaner container.
CAUTION
Using anything but recommendedcleaners and procedures may affect the fabric’s appearance and fire-resistant properties.
CAUTION
Do not scrape or scratch the inside of the rear window. This may resultin damage to the rear window defroster grid.
WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
water enters the engine or hybrid
battery in the trunk, electric shocks
or burns may result in serious injury
or death.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations.
There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-
al.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch.
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.
1. Crankcase emission control system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative emission control(including ORVR: Onboard
Refueling Vapor Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel vapors
from escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be
loaded into a canister while refueling at
the gas station, preventing the escape of
fuel vapors into the atmosphere.)
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 solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant tempera-
ture is low during idling, the PCSV closes
so that evaporated 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 performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or dura-
bility and may even violate governmen-
tal 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. It may also cause
wire damage, battery discharge and
fire. For your safety, do not use unau-
thorized electronic devices.
Engine exhaust gas precautions (car-bon 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 sus-
pect 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 car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine exhaust and a wide variety
of automobile components and
parts, including components found
in the interior furnishings in a vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm.

779
Maintenance
Do not operate the engine in confinedor 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 vehi- cle 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 catalyticconverters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for gaso- line engines.
Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance. 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 sys-
tem. 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.
WARNING- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegetation,
paper, leaves, etc.

CALIFORNIA PERCHLORATE NOTICE
Your vehicle is equipped with a high volt-
age battery. An inappropriately disposed
high voltage battery can be harmful to
the environment and human health and
could result in death or serious injury.
To dispose the high voltage battery con-
tact an authorized HYUNDAI dealer.Perchlorate Material-special handling
may apply, See www.dtsc.ca.gov/haz-
ardouswaste/perchlorate.
Notice to California Vehicle Dismantlers:
Perchlorate containing materials, such as
air bag inflators, seatbelt pretensioners
and keyless remote entry batteries, must
be disposed of according to Title 22
California Code of Regulations Section
67384.10 (a).
