When driving
IS F_EE
CAUTION
When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
push and hold the “ENGINE START STOP” switch for more than 3 sec-
onds.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. Turning the engine off while driving will not cause
loss of steering or braking control, but the power assist to these systems will
be lost. This will make it more difficult to steer and brake, so you should
pull over and stop the vehicle as soon as it is safe to do so.

Do not leave the “ENGINE START STOP” switch in ACCESSORY or
IGNITION ON mode for long periods without the engine running.
When starting the engine

to the prevailing weather conditions.
Pre-winter preparations
Use fluids that are appropriate to the prevailing outside
temperatures.
• 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.
Ensure that all tires are the specified size and the same brand.
Tire chains cannot be installed on 19-inch tires. Use the
specified type of tire chains and install them on the rear
tires only. Before installing the tire chains, change all four
tires and wheels to those of the specified size (tires: 225/
40R18, wheels: 18x8JJ +45 offset). For details, contact any
authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Before driving the vehicle

Do not try to forcibly open a window or move a wiper that
is frozen. Pour warm water over the frozen area to melt the
ice. Wipe away the water immediately to prevent it from

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

IS F_EE
EON (Enhanced Other Network) system (for traffic announcement func-
tion)
If the RDS station (with EON data) you are listening to is not broadcasting a
traffic information program and the audio system is in the TA (traffic

broadcasting a traffic information program in the EON AF list when traffic
information begins.
