Your vehicle is equipped with an
emission control system to meet all

There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-
tem

tem
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it is

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

1. Crankcase emission control
system
The positive crankcase ventilation
and
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.
