SYSTEM OVERVIEW

Exhaust System
Check the complete exhaust system and the nearby body
areas and trunk lid for broken, damaged, missing or
mispositioned parts, open seams, holes, loose
connections, or other deterioration which could permit
exhaust fumes to seep into the trunk may be an indication
of a problem in one of these areas. Any defects should be
corrected immediately.
Notice
When you are inspecting or replacing exhaust system
components, make sure there is adequate clearance
from all points on the underbody to avoid possible
overheating of the floor panel and possible damage to
the passenger compartment insulation and trim
materials.

DOC (Diesel Oxidation Catalyst)

DOC (Diesel Oxidation Catalyst) is the purification device
to reduce the toxic emissions from the exhaust gas from
the engine. By using the chemical reaction, the amount of
toxic gas such as NOx can be reduced.
Notice
To prevent damage of DOC, never contact the lift pad
when lifting up the vehicle.
EXHAUST SYSTEM
DI ENG SM - 2004.4
Muffler
Aside from the exhaust manifold connection, the exhaust
system uses a flange and seal joint design rather than a
slip joint coupling design with clamp and U-bolts. If hole,
open seams, or any deterioration is discovered upon in-
spection of the front muffler and pipe assembly, the com-
plete assembly should be replace, the complete assem-
bly should be replaced. The same procedure is applicable
to the rear muffler assembly. Heat shields for the front and
rear muffler assembly and catalytic converter protect the
vehicle and the environment from the high temperatures
that the exhaust system develops.

Heat Shield

The heat shield protects the vehicle and components from
the high heat generated from the exhaust system.
In this vehicle, the heat shield to block the heat from DOC
is installed to the underbody, and the heat shield to block
the heat from the rear muffler is installed to the underbody
between the fuel tank and the rear muffler.

Hanger

The hanger is to support the components.
If the ganger is not properly installed, it may cause the
vibration that is very difficult to diagnose. Therefore, install
the hanger to the correct location so that the exhaust sys-
tem cannot contact to the underbody and other
components.
