Curb Weight
This means the weight of a motor vehicle
with standard and optional equipment
including the maximum capacity of fuel,
oil and coolant, but without passengers
and cargo.
DOT Markings
A code molded into the sidewall
of a tire signifying that the tire is in
compliance with the U.S. Department
of Transportation motor vehicle safety
standards. The DOT code includes the
Tire Identification Number (TIN), an
alphanumeric designator which can
also identify the tire manufacturer,
production plant, brand and date of
production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the Front
Axle.
GAWR RR
Gross Axle Weight Rating for the Rear
axle.
Intended Outboard Sidewall
The side of an asymmetrical tire,
that must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light truck (LT) tire
A tire designated by its manufacturer as
primarily intended for use on lightweight
trucks or multipurpose passenger
vehicles.
Load ratings
The maximum load that a tire is rated to
carry for a given inflation pressure.
Load Index
An assigned number ranging from 1 to
279 that corresponds to the load carrying
capacity of a tire.
Maximum Inflation Pressure
The maximum air pressure to which a
cold tire may be inflated. The maximum
air pressure is molded onto the sidewall.
Maximum Load Rating
The load rating for a tire at the maximum
permissible inflation pressure for that
tire.
Maximum Loaded Vehicle Weight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight
The number of occupants a vehicle
is designed to seat multiplied by 150
pounds (68 kg).
Occupant Distribution
Designated seating positions.
Outward Facing Sidewall
An asymmetrical tire has a particular
side that faces outward when mounted
on a vehicle. The outward facing
sidewall bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or deeper
than the same moldings on the inner
facing sidewall.
Passenger (P-Metric) tire
A tire used on passenger cars and some
light duty trucks and multipurpose
vehicles.

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.
