Maintenance
Purge Control Solenoid Valve (PCSV)
The Purge Control Solenoid Valve
(PCSV) 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 evapo-
rated fuel to the engine.
3. Exhaust emission control system
The exhaust emission control sys-
tem is a highly effective system
which controls exhaust emissions
whilst maintaining good vehicle per-
formance.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present
with other exhaust fumes. There-
fore, 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
Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though colour-
less and odourless, it is dangerous
and could be lethal if inhaled. Follow
the instructions on this page to
avoid CO poisoning.
Do not operate the engine in con-
fined 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.
