3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present with
other exhaust fumes. Therefore, if
you smell exhaust fumes of any kind
inside your vehicle, have it inspected
and repaired immediately. If you ever
suspect exhaust fumes are coming
into your vehicle, drive it only with
all the windows fully open. Have
your vehicle checked and repaired
immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
following to avoid CO poisoning.
• Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
• When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
• Never sit in a parked or stopped
vehicle for any extended time with the
engine running.
• When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system.
Operating precautions for catalytic
converters (if equipped)
WARNING
• A hot exhaust system can ignite
flammable items under your vehicle.
Do not park, idle, or drive the vehicle
over or near flammable objects, such
as dry grass, paper, leaves, etc.
• The exhaust system and catalytic
system are very hot while the engine
is running or immediately after the
engine is turned off. Keep away from
the exhaust system and catalytic
converter as you may get burned.
Also, do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle and
do not coat the vehicle for corrosion
control. It may present a fire risk
under certain conditions.
