Regeneration Required
Warning Light
REGEN. REQUIRED
This light (amber) comes on when
Running regeneration or Switch
regeneration is required. When this
light comes on, perform DPF
regeneration soon. If the engine
continues to run without performing
DPF regeneration, this light will
change color from amber to red.
If this light turns red, perform DPF
regeneration immediately. If you do
not perform DPF regeneration, the
check engine malfunction indicator
light and reduced engine power
indicator light will come on,
imposing performance restriction on
the vehicle. If this happens, the
vehicle must be serviced at your
dealer. See Diesel Particulate Filter

Regeneration in Progress
Light
REGEN. IN PROGRESS
When this light is ON, DPF
regeneration is in progress. When
the vehicle is stationary, the exhaust
sound changes as the engine speed
increases. Also, operating sounds of
the exhaust throttle may be heard. Keep people and flammable objects
away from the exhaust pipe,
because the exhaust temperature
becomes high during regeneration.
When regeneration is completed,
the light goes out automatically. See
Diesel Particulate Filter
0180.
During extended engine idling, this
light may appear on the DIC and the
DPF may be automatically
regenerated.
Checking PM Level Light
CHECKING PM LEVEL
In the case of performing the
"Selectable" regeneration, this light
comes on when the DPF switch is
kept held down. While this light is
ON, the system is checking whether
or not the "Selectable" regeneration
is possible. If the "Selectable"
regeneration is possible, the light
changes to the selectable (switch)
regeneration required warning light.
If the indication does not change to
the selectable (switch) regeneration
required warning light, the
"Selectable" regeneration is not
possible.
Exhaust System Warning Light
EXH. SYSTEM

Radio Reception
Usually, a problem with radio
reception does not mean there is a
problem with your radio - it is just the normal result of conditions
outside the vehicle. For example,
nearby buildings and terrain can
interfere with FM reception. Power
lines or telephone wires can
interfere with AM signals.
And of course, radio signals have a
limited range. The farther you are
from a station, the weaker its signal
will be. In addition, reception
conditions change constantly as
your vehicle moves.
Here are some common reception
problems that probably do not
indicate a problem with your radio.
FM Transmissions
Fading and drifting stations -
Generally, the effective range of FM
is about 40 km (25 miles). Once
outside this range, you may notice
fading and drifting, which increase
with the distance from the radio
transmitter. They are often
accompanied by distortion.
Multi-path - FM signals are
reflective, making it possible for two
signals to reach your antenna at the
same time. If this happens, the
signals will cancel each other out,
causing a momentary flutter or loss
of reception.
Static and fluttering - These occur
when signals are blocked by
buildings, trees, or other large
objects. Increasing the bass level
may reduce static and fluttering.
Station swapping - If the FM signal
you are listening to is interrupted or
weakened, and there is another
strong station nearby on the FM
band, your radio may tune in the
second station until the original
signal can be picked up again.
AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere -
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,
