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.

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.
■
