or some of the removed label still
attached to it. Using the disc like
this may cause the disc to not eject
properly and damage the disc.
Discs with Special Shapes
Heart-shaped or octagon-shaped
discs cannot be played. Do not use
them as they may cause damage.
Disc Accessories
Do not use commercially available
accessories (such as stabilizers,
protective seals, etc.) that are said
to improve sound quality or protect
the discs, and CD labels, etc. They
may change the thickness of the
disc and external specifications and
lead to damage.
Do not use commercially available
accessories (such as CD rings,
protectors) that are said to improve
sound quality or are effective
against vibrations. They may come
off inside the device, causing the
disc to become unplayable or
unretrievable and lead to
malfunction.Supported MP3/WMA File
Standards
MP3 (MPEG Audio LAYER 3) is a
standard format for sound
compression technology.
MP3 can compress a file to
one-tenth of its original size.
WMA (Windows Media™
Audio) is a
Microsoft sound compression
format. It can compress sounds to a
smaller size than the MP3.
MP3/WMA files recorded in the
CD-ROM, CD-R, and CD-RW can
be played.
Discs formatted in the ISO9660
level 1 and 2, Romeo and Joliet file
system can be used.
Files with extensions compatible to
MP3 and WMA can be played
(.mp3, .wma).
CD-R and CD-RW compatible to
multisessions and also have MP3/
WMA files can be played.
Compatible with ID3 tag ver.1.0,
ver.1.1, ver.2.2 and ver.2.3.
Compatible to WMA tag. The sampling frequency and bit rate
corresponds as follows.

a gasoline engine. So, your engine
must crank faster than a gasoline
engine before it will start.
To be sure the engine can turn fast
enough to start, use SAE 10W-40
viscosity engine oil when prevailing
temperatures drop below 0 °C (32 °
F). See the oil quality and oil
viscosity recommendations. Using
the proper viscosity oil will make
starting easier down to -23 °C (-10 °
F). When prevailing temperatures
drop below -23 °C (-10 °F), the
optional engine block heater may be
needed for starting.
Maintenance Items to Aid Cold
Weather Starting
Since the basic principle of diesel
engine ignition is based on
compression, the diesel engine is
somewhat harder to start than a
gasoline engine when the
temperature is below freezing.
To help prevent hard starting
problems, special attention should
be given to following normal
maintenance items:1. Neglecting to have the fuel
filter and water separator
serviced can be one of the
major contributors to hard
starting. If water is permitted to
accumulate in the primary filter,
it will freeze and make starting
the engine impossible.
2. Make sure the fuel tank vent is open.
3. Always refuel at the end of a day's operation. Moisture will
condense in an empty tank;
therefore, the tank should be
filled before leaving the vehicle
standing for an extended
period.
Do not use starting aids in the air
intake system. Such aids can cause
immediate engine damage. See
Fuel for Diesel Engines 0232.
Stopping the Engine
When stopping the diesel engine,
take the following steps: 1. Bring the vehicle to a complete stop.
2. Firmly apply the parking brake. 3. Move the selector lever to the
P position and make sure that
the shift indicator shows P.
4. Allow the engine to idle for approximately 3 minutes.
5. Turn the engine control switch to the ACC or LOCK position.
Do not shut down the engine
immediately after driving the vehicle.
Otherwise, a seizure or other
failures may result.
To prevent the battery from going
dead, turn the engine control switch
to the ACC or LOCK position after
stopping the engine. If you leave the
vehicle for an extended period of
time, place the engine control switch
in the LOCK position.
Let the engine idle for 3 minutes
before shutting off the engine. This
allows the turbocharger to slow
down while keeping the bearings
lubricated.
