Maintenance
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire
inflation pressures
All tire pressures (including the spare)
should be checked when the tires are
cold. “Cold Tires” means the vehicle has
not been driven for at least three hours
or driven less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehicle
handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in chapter 2.

All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
WARNING
Tire underinflation
Severe underinflation (70 kPa (10 psi) or
more) can lead to severe heat build-up,
causing blowouts, tread separation and
other tire failures that can result in the
loss of vehicle control leading to severe
injury or death. This risk is much higher
on hot days and when driving for long
periods at high speeds.
NOTICE
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, we recommend that the
system be checked by an authorized
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.
NOTICE
• Warm tires normally exceed
recommended cold tire pressures
by 28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to adjust
the pressure or the tires will be
underinflated.
• 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.

Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control systems
which are 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 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 control
system
The Evaporative Emission Control
System is designed to prevent
fuel vapors from escaping 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.
