LS500_OM_(U)_1810 4-6.Driving tips
 Use fluids that are appropriate to
the prevailing outside temperatures. •Engine oil
• Engine coolant
•Washer fluid
 Have a service technician inspect
the condition of the battery.
 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 specified size
and brand, and that chains match the size
of the tires. *
: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.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. ■
When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height
control of the electronically modulated
air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. (  P.293)■
Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower. ●
Avoid driving on bumpy road surfaces
or over potholes. ●
Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●
Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●
Do not use LTA (Lane Tracing Assist)
system.

NOTICE■
To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels, etc.)●
Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the
paint surface
• If dead insects, in sect droppings or
bird droppings are present on the
paint surface
• After driving in an area contaminated
with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled
with dust or mud
• If liquids such as benzene and gasoline
are spilled on the paint surface ●
If the paint is chipped or scratched,
have it repaired immediately. ●
To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels. ■
Cleaning the exterior lights ●
Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights. ●
Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses. ■
When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged. ■
When using a high pressure car wash ●
When washing the vehicle, do not
spray the camera or its surrounding
area directly with a high pressure
washer. Shock applied from high pres-
sure water may cause the device to not
operate normally. ●
Do not bring the nozzle tip close to
boots (rubber or re sin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts

WARNING
The engine compartment contains many
mechanisms and fluids that may move
suddenly, become hot, or become elec-
trically energized. To avoid death or seri-
ous injury, observe the following
precautions. ■
When working on the engine com-
partment●
Keep hands, clothi ng and tools away
from the moving fan and engine drive
belt.●
Be careful not to touch the engine,
radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil
and other fluids may also be hot.
●
Do not leave anything that may burn
easily, such as paper and rags, in the
engine compartment.
●
Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are
flammable.
■
When working near the electric cool-
ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION
ON mode, the electric cooling fan may
automatically start to run if the air condi-
tioning is on and/or the coolant tempera-
ture is high. (  P.378)Items Parts and tools ■
Safety glasses
Wear safety glasses to prevent flying or
falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE■
If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine

B WARNING■
When installing the tire
Failure to follow these precautions could
cause the wheel nuts to loosen and the
tire to fall off, result ing in death or serious
injury. ●
Never use oil or grease on the wheel
bolts or wheel nuts.
Oil and grease may cause the wheel
nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In
addition, the oil or grease can cause
the wheel nuts to loosen and the wheel
may fall off, causing a serious accident.
Remove any oil or grease from the
wheel bolts or wheel nuts. ●
Have the wheel nuts tightened with a
torque wrench to 103 ft•lbf (140 N•m,
14.3 kgf•m) as soon as possible after
changing wheels. ●
Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving. ●
When installing a tire, only use wheel
nuts that have been specifically
designed for that wheel. ●
If there are any cracks or deformations
in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle
inspected by your Lexus dealer.
