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 same size and 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.

■Micro dust and pollen filter
●In order to prevent the windows 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 .
■When the indicator light on “A/C” flashes
Touch “A/C” and turn off the air conditioning system before turning it on once more.
There may be a problem in the air conditioning system if the indicator light contin-
ues to flash. Turn the air conditioning system off and have it inspected by your Lexus
dealer.
■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 automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The differ-
ence 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 12 volt battery discharge
Do not leave the automatic air conditioning system on longer than necessary when
the engine is off.
