Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the level and specific gravity of
battery electrolyte.
●Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the specified size and the same brand, and that
chains match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Remove any ice that has accumulated on the vehicle chassis.
●Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.

3-1. Using the air conditioning system and defogger
Rear outlets
Direct air flow to the left or right,
up or down
Turn the knob fully to the outside
of the vehicle to close the vent
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur.
●Immediately after is pressed, the fan may stop for a while until warm or
cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.
■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used for an extended
period.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched in accor-
dance with the temperature setting and the inside temperature.
■Window defogger feature
Recirculated air mode may automatically switch to
(outside air) mode in situ-
ations where the windows need to be defogged.
■When outside air temperature approaches 32F (0C)
The air conditioning system may not operate even when is pressed.

Interior features
■Automatic mode for air intake control (IS350 only)
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold,
the following may occur.
• Outside air mode does not switch to .
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immedi-
ately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the automatic air conditioning system on longer than necessary when
the engine is off.

The “ENGINE START STOP” switch is in IGNITION ON mode.
CAUTION
■When the outside rear view mirror defoggers are on
Do not touch the outside surface of the rear view mirror, as it can become very hot

These features are used to defog the rear window, and to remove rain-
drops, dew and frost from the outside rear view mirrors.

3-2. Using the audio system
■When the battery is disconnected
Station presets are erased.
■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually
changing position of the antenna, differences in signal strength and surrounding
objects, such as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.

3-2. Using the audio system
■Discs that can be used
Discs with the marks shown below can be used.
Playback may not be possible depending on recording format or disc features, or
due to scratches, dirt or deterioration.
■CD player protection feature
To protect the internal components, playback is automatically stopped when a
problem is detected while the CD player is being used.
■If CDs are left inside the CD player or in the ejected position for extended peri-
ods
CDs may be damaged and may not play properly.
■Lens cleaners
Do not use lens cleaners. Doing so may damage the CD player.
■MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1 /10 of their original size by using MP3
compression.
WMA (Windows Media
TM Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards and to the media/formats
recorded by them that can be used.
●MP3 file compatibility
• Compatible standards
MP3 (MPEG1 LAYER3, MPEG2 LSF LAYER3)
• Compatible sampling frequencies
MPEG1 LAYER3: 32, 44.1, 48 (kHz)
MPEG2 LSF LAYER3: 16, 22.05, 24 (kHz)
• Compatible bit rates (compatible with VBR)
MPEG1 LAYER3: 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 (kbps)
MPEG2 LSF LAYER3: 64, 80, 96, 112, 128, 144, 160 (kbps)
• Compatible channel modes: stereo, joint stereo, dual channel and monaural

3-2. Using the audio system
●ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title
and artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags. (The
number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
●MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.
●Playback
• To play MP3 file with steady sound quality, we recommend a fixed bit rate of
128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3
and WMA files on the market, and depending on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be
possible at all.

Microsoft Corporation in the U.S.A. and other countries.
