EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle is
being driven in severe conditions, morefrequent oil and filter changes arerequired.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for proper tension and adjusted as neces-
sary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is correctly replaced.

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 vehicle
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 valveinto 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 atmos-
phere.
(The ORVR system is designed to allow
the vapors from the fuel tank to beloaded into a canister while refueling at
the gas station, preventing the escape of
fuel vapors into the atmosphere.)
