Maintenance
Changing Engine Coolant
Have coolant changed by an author-
ized retailer of Genesis Branded
products according to the
Maintenance Schedule at the begin-
ning of this chapter.
To prevent damage to engine
parts, put a thick towel around the
radiator cap before refilling the
coolant to prevent the coolant
from overflowing into engine
parts, such as the alternator.
NOTICE
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control
resulting in an accident.
Engine coolant may also cause
damage to paint and body trim.
WARNING
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning
counterclockwise to remove it.
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
Always turn off the engine
unless the vehicle has to be
inspected with the engine on.
Be cautious as the cooling fan
may operate if the negative (-)
battery terminal is not discon-
nected.

If soiled, the air cleaner filter must be
replaced.
Visit an authorized retailer of
Genesis Branded products to
replace the air cleaner filter.
Replace the filter according to the
Maintenance Schedule
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the air
cleaner filter more often than the
usual recommended intervals (refer to
"Maintenance Under Severe Usage
Conditions" in this chapter). Do not drive with the air cleaner
filter removed. This will result in
excessive engine wear.
When removing the air cleaner filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use Genuine Genesis Part, use of non-Genuine Genesis Part
could damage the engine.

Maintenance
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) Crankcase emission control sys- tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control 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 retailer of Genesis
Branded products in accordance
with the maintenance schedule in
this manual.
For the Inspection and Maintenance
Test (
with Electronic Stability Control
(ESC)
system)
To prevent the vehicle from mis- firing during dynamometer test-
ing, 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 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 ControlSystem Including Onboard
Refueling Vapor Recovery
(ORVR)
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 be loaded into a can-
ister while refueling at the gas sta-
tion, 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 sole-
noid valve.
