cle
• When approaching the side or front of a
vehicle
• If a preceding vehicle has a small rear
end, such as an unloaded truck
• If a preceding vehicle has a low rear end,
such as a low bed trailer
• If a vehicle ahead is carrying a load which
protrudes past its rear bumper
• If a vehicle ahead has extremely high
ground clearance
• If a vehicle ahead is irregularly shaped,
such as a tractor or side car
• If the sun or other light is shining directly
on a vehicle ahead
• If a vehicle cuts in front of your vehicle or emerges from beside a vehicle
• If a vehicle ahead makes an abrupt
maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preced-
ing vehicle
• When a vehicle ahead is not directly in
front of your vehicle
• When driving in incl ement weather such
as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow,
dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the sur-
rounding brightness changes suddenly,
such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun
or the headlights of oncoming traffic,
shines directly into the camera sensor
• When the surrounding area is dim, such
as at dawn or dusk, or while at night or in
a tunnel
• After the hybrid system has started the
vehicle has not been driven for a certain
amount of time
• While making a left/r ight turn and for a
few seconds after making a left/right turn
• While driving on a curve and for a few
seconds after driving on a curve
• If your vehicle is skidding
• If the front of the vehicle is raised or low-
ered

Parking precaution
If the vehicle is parked for a long time, the
vehicle height may change due to
changes in the ambient temperature.
When parking the vehicle, make sure
that the area above and below the vehi-
cle is clear, so that the vehicle will not
contact anything if its height changes.
Be careful when parking the vehicle in an
area with a low ceiling or near low hang-
ing objects, as the vehicle height will
increase when passengers exit the vehi-
cle and the access mode control oper-
ates.

310 4-6. Driving tips
LS500h_OM_OM50F42U_(U) Perform the following according to the
driving conditions:
Do not try to forcib ly 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
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.
Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions. Park the vehicle and shift the shift posi-
tion to P without setting the parking
brake. The parking brake may freeze
up, preventing it from being released. If
the vehicle is parked without setting
the parking brake, make sure to block
the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly leading to
an accident.
Vehicles with front and rear tires of
the same size
Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire
size.
Side chain (0.12 in. [3 mm] in diam-
eter)
Cross chain (0.16 in. [4 mm] in
diameter)
Vehicles with front and rear tires of
differing sizes
Tire chains cannot be mounted.
Snow tires should be used instead.NOTICE■
Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.

Switching between outside air and
recirculated air modes
Press the outside/recirculated air
mode switch. The mode changes as follows each time
the switch is pressed.
automatic mode → (outside air
mode) → (recirculated air mode)
→ automatic mode
When the system is switched to automatic
mode, the air conditioning system operates
automatically. ■
Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch. Set the outside/reci rculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch auto-
matically.)
To defog the windshield and the side win-
dows quickly, turn the air flow and tem-
perature up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■
Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.
The defoggers will automatically turn off after a while. The operation time changes
according to the ambient temperature and
vehicle speed. ■

When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on ●
In order to reduce the air conditioning
power consumption, the air conditioning
system may switch to recirculated air
mode automatically. This may also
reduce fuel consumption. ●
It is possible to switch to outside air mode
at any time by pressing the outside/recir-
culated air mode switch. ■
Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning “A/C”
on will dehumidify the air from the outlets
and defog the windshield effectively. ●
If you turn “A/C” off, the windows may fog
up more easily. ●
The windows may fog up if the recircu-
lated air mode is used. ■
Outside/recirculated air mode ●
When driving on dusty roads such as tun-
nels or in heavy traffic, set the out-
side/recirculated air mode switch to the
recirculated air mode. This is effective in
preventing outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirc ulated air mode will
also cool the vehicle interior effectively.
●
Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■
Registering air conditioning settings to
electronic keys
●
Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.
