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-

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.

●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 th e disc and in some cases, playback may not be
possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of
Microsoft Corporation in the U.S.A. and other countries.
