Driving tips
. Avoid racing the engine.
. Never turn off the ignition switch while
the vehicle is moving.
. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), we re-
commend that you have your vehicle
checked and repaired by an authorized
SUBARU dealer.
. Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-
tem.
. Do not drive with an extremely low fuel
level.
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-
tures.
. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.
Diesel particulate filter (die-
sel engine models)
1) Catalytic converter
2) Diesel particulate filter
The diesel particulate filter is a device that
eliminates particulate matter in the ex-
haust gas of a diesel engine.
In most cases, the accumulated soot is
automatically burned in the filter while
driving. However, accumulated soot in the
filter is not burned if you drive the vehicle
under the following conditions.
. When the vehicle is continuously dri-
ven at 15 km/h (9 mph) or less
. When the vehicle is driven without
sufficient preheating or the vehicle is
repeatedly driven for only a short period
of time
. When the vehicle is idling for a long
time
S08AP
The diesel particulate filter warning light

WARNING

filter operates at very high tem-
peratures.
