Filter Inspection
The cabin air filter should be replaced
according to the Maintenance Schedule.
If the vehicle is operated in severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and replaced
earlier. When you replace the cabin air
filter, replace it performing the following
procedure, and be careful to avoid
damaging other components.
Filter replacement
OCN7080013
1. Push in both sides of the glove box as
shown. This will ensure that the glove
box stopper pins will get released
from its holding location allowing the
glove box to hang.

2. Remove the cabin air filter case while
pr essing the lock on the right side of
the cover.

3. Replace the cabin air filter.
4.
Reassemble in the r
everse order of
disassembly.
NOTICE
Install a new cabin air filter in the correct
direction with the arrow symbol (↓)
facing downwards, otherwise, it may be
noisy and the effectiveness of the filter
may be reduced.

Tire Rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
according to the maintenance schedule
or sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pressure,
improper wheel alignment, out-of-
balance wheels, severe braking or severe
cornering. Look for bumps or bulges in
the tread or side of the tire. Replace the
tire if you find any of these conditions.
Replace the tire if fabric or cord is visible.
After rotation, be sure to bring the front
and rear tire pressures to specification
and check lug nut tightness (proper
torque is 79~94 lbf·ft [11~13 kgf·m]).
„„Without a spare tire
OHI078078
Disc brake pads should be inspected for
wear whenever tires are rotated.
Information
Tires that are asymmetrical or
directional can only be installed
on the wheel in one direction. The
outside and inside of an asymmetrical
tire is not easily distinguishable. Pay
careful attention to the markings on
the sidewalls of the tires, noting the
“outside” marking and also the rotating
direction before installing them on the
vehicle.
WARNING
• Do not use the compact spare tire for
tire rotation.
• Do not mix bias ply and radial ply
tires under any circumstances.
This may cause unusual handling
characteristics that may cause loss
of vehicle control resulting in an
accident.

Maintenance
9-68
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
booklet in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations. There
are three emission control systems, as
follows.
(1)
Crank
case emission control system
(2)
Ev

aporative emission control system
(3)
Exhaust emission con

trol system
In order to ensure the proper function
of the emission control systems, it
is recommended that you have your
vehicle inspected and maintained
by an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)
• To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).
• After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
1. Crankcase Emission Control
Sy
stem
The positive crankcase ventilation system
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
System Including Onboard
Refueling Vapor Recovery
(ORVR)
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 controlled by the Engine Control
Module (ECM); when the engine coolant
temperature 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.
