Driving
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.
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.
 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.
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
■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.

2436-1. Maintenance and care

Maintenance and care
WARNING
■Precautions regarding the exhaust
pipes
As exhaust gases cause the exhaust
pipes to become quite hot, do not touch
the exhaust pipes while the engine is run-
ning or immediately after the engine is
turned off.
When washing the vehicle, be careful not
to touch the exhaust pipes until they have
cooled sufficiently, as touching hot
exhaust pipes can cause burns.
■Precaution regarding the rear
bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped
or scratched, the system may malfunc-
tion. If this occurs, consult your Lexus
dealer.
NOTICE
■Application of coatings to the vehicle
body (vehicles wi th CFRP parts)
Do not apply any kind of coating to the
vehicle body as doing so may damage
the paint or reduce its durability.
■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.
■To prevent damage to the windshield
wiper arms
When lifting the wiper arms away from
the windshield, pull the driver side wiper
arm upward first, and repeat for the pas-
senger side. When returning the wipers
to their original position, do so from the
passenger side first.
■When using an automatic car wash
(vehicles with rain-sensing windshield
wipers)
Set the wipers to the intermittent wind-
shield wipers. ( P.143)
If AUTO mode is selected, the wipers
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.

2446-1. Maintenance and care
NOTICE
●Do not bring the nozzle tip close to
boots (rubber or resin 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
•Suspension parts
•Steering parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged. Also, do not
continuously hold the nozzle in the
same place.
●Do not spray the lower part of the
windshield continuously.
If water enters the air conditioning sys-
tem intake located near the lower part of
the windshield, the ai r conditioning sys-
tem may not operate correctly.
●Do not wash the underside of the vehi-
cle using a high pressure car washer.
●Do not point the nozzle of a high pres-
sure washer at the areas shown in the
illustration, as high pressure water may
damage the oil coolers.
■Hood vent
When washing the vehicle, do not allow a
large amount of water to enter the hood
vent at once, such as when using a
bucket, etc. or point the nozzle of a high
pressure washer at the hood vent.
Water may get inside the engine com-
partment and affect the engine and other
components.

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 fans 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.
ItemsParts and tools●Do not smoke, cause sparks or expose
an open flame to fuel or the battery.
Fuel and battery fumes are flammable.
●Be extremely cautious when working
on the battery. It contains poisonous
and corrosive sulfuric acid.
■When working near the electric cool-
ing fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION
ON mode, the electric cooling fans may
automatically start to run if the air condi-
tioning is on and/or the coolant tempera-
ture is high. ( P.270)
■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
wear due to dirt in the air.
