Maintenance
•Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures at the proper levels. If a
tire frequently needs refilling,
we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
•Overinflation produces a
harsh ride, excessive wear at
the center of the tire tread,
and a greater possibility of
damage from road hazards.
CAUTION
•Warm tires normally exceed
recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
•Be sure to reinstall the tire
inflation valve caps. Without
the valve cap, dirt or moisture
could get into the valve core
and cause air leakage. If a
valve cap is missing, install a
new one as soon as possible.
CAUTION
Tire pressure
Always observe the following:
•Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't been driv-
en more than 1.6 km (1 mile)
since startup.)
•Check the pressure of your
spare tire each time you check
the pressure of other tires.
•Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
•Wo r n , o l d t i r e s c a n c a u s e
accidents. If your tread is
badly worn, or if your tires
have been damaged, replace
them.
CAUTION
Tire inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.

Maintenance
EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passpor t in your vehicle.
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 n
emission control system to meet all
emission regulations.
There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
1. Crankcase emission control
system
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 con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
For the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
•To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch.
•After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
