When driving
IS250/220d/200d_EERetighten the chains after driving 0.5 1.0 km (1/4 1/2
mile).
Tire chains (models with 16- and 17-inch tires)
Observe the following precautions when installing and removing chains.
Install and remove tire chains in a safe location.
Install tire chains on the rear tires. Do not install tire chains on front tires.
Install tire chains following the instructions provided in the accompany-
ing manual.
CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Driving with tire chains (models with 16- and 17-inch tires)
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.

3-1. Using the air conditioning system and defogger
IS250/220d/200d_EE
Automatic mode for air intake control (IS250 only)
In automatic mode, the system detects exhaust gas and other pollutants and
automatically switches between outside air and recirculated air modes.
Pollen removal mode
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 immediately after the air conditioning system is started in auto-
matic mode.
CAUTION
To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather.
The difference 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 air conditioning system on longer than necessary when the
engine is stopped.

MP3 and WMA files
MP3 (MPEG Audio LAYER3) 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 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/for-
mats recorded by them that can be used.
