2384-6. Driving tips
Use fluids that are appropriate to 
the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Power control unit coolant (LC500h)
•Washer fluid
Have a service technician inspect 
the condition of the 12-volt battery.
 Have the vehicle fitted with four 
snow tires.
Ensure that all tires are the specified size 
and the same brand.
Perform the following according to the 
driving conditions:
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 
freezing.
 When the outside door handle is 
frozen, unlock the doors using the 
wireless remote control. If the out-
side door handles remain retracted 
and do not move even if the doors 
are unlocked using the wireless 
remote control, pour warm water 
over the frozen area to melt the ice 
and wipe away the water immedi-
ately to prevent it from freezing. The 
outside door handle may not retract 
due to ice, however, the outside 
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the 
climate control system fan, remove 
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving 
the vehicle in winter. Always drive 
the vehicle in a manner appropriate 
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to 
reduce the risk of accidents. 
Failure to do so may result in a loss of 
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air 
pressure.
●Do not drive in excess of 75 mph (120 
km/h), regardless of the type of snow 
tires being used.
●Use snow tires on all, not just some 
wheels.
NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may 
damage the vehicle body and suspen-
sion, and adversely affect driving perfor-
mance.
■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.

3026-3. Do-it-yourself maintenance
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on 
a tire.
●You have tire damage such as cuts, splits, 
cracks deep enough to expose the fabric, 
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be 
properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus 
dealer.
■Tire life
Any tire over 6 years old must be checked 
by a qualified technician even if it has sel-
dom or never been used or damage is not 
obvious.
■Low profile tires (21-inch tires)
Generally, low profile tires will wear more 
rapidly and tire grip performance will be 
reduced on snowy and/or icy roads when 
compared to standard ti res. Be sure to use 
snow tires on snowy and/or icy roads and 
drive carefully at a speed appropriate for 
road and weather conditions.
■Maximum load of tire
Check that the maximum load of the 
replacement tire is greater than 1/2 of the 
Gross Axle Weight  Ratings (GAWR) of 
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label. 
For the maximum load of the tire, see the 
load limit at maximum cold tire inflation 
pressure mentioned on the sidewall of the 
tire. ( P.383)
■Tire types
●Summer tires Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer 
tires do not have the same traction per-
formance as snow tires, summer tires are 
inadequate for driving on snow-covered 
or icy roads. For driving on snow-covered 
roads or icy roads, the use of snow tires is 
recommended. When installing snow 
tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide 
better traction in 
snow and to be ade-
quate for driving in most winter condi-
tions as well as for use year-round. All 
season tires, howeve r, do not have ade-
quate traction performance compared 
with snow tires in heavy or loose snow. 
Also, all season tires fall short in accelera-
tion and handling performance com-
pared with summer  tires in highway 
driving.
●Snow tires
For driving on snow-covered roads or icy 
roads, we recommend us ing snow tires. If 
you need snow tires,  select tires of the 
same size, construction and load capacity 
as the originally installed tires. Since your 
vehicle has radial tires as original equip-
ment, make sure your snow tires also 
have radial construction. Do not install 
studded tires without first checking local 
regulations for possible restrictions. 
Snow tires should be installed on all 
wheels. ( P.238)
■If the tread on snow tires wears down 
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is 
lost.
WARNING
■When inspecting or replacing tires
Observe the following precautions to 
prevent accidents.
Failure to do so may cause damage to 
parts of the drivetrain  as well as danger-
ous handling characteristics, which may 
lead to an accident  resulting in death or 
serious injury.

When trouble arises
7-2.Steps to take in an emergency
If your vehicle needs to be 
towed
If towing is necessary, we recom-
mend having your vehicle towed by 
your Lexus dealer or commercial 
towing service, using a wheel-lift 
type truck or flatbed truck.
Use a safety chain system for all 
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions. 
Failure to do so may result in death or 
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle 
with all four wheels raised off the ground. 
If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and 
related parts may be damaged or an 
accident may occur due to a change in 
direction of the vehicle.
LC500h: Be sure to transport the vehi-
cle with all four wheels raised off the 
ground. If the vehicle is towed with the 
tires contacting the ground, the drive-
train and related parts may be damaged, 
an accident may occur due to a change 
in direction of the vehicle or electricity 
generated by the operation of the motor 
may cause a fire to occur depending on 
the nature of the damage or malfunction.
■While towing
●When towing using cables or chains, 
avoid sudden starts, etc. which place 
excessive stress on the towing eyelets, 
cables or chains. The towing eyelets, 
cables or chains may become dam-
aged, broken debris may hit people, 
and cause serious damage.
●Do not turn the engine switch 
switch> off. 
This may lead to an accident as the 
rear wheels will be locked by the park-
ing lock. 
Also, there is a possibility that the 
steering wheel is locked and cannot be 
operated.
