8 Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
The wipers will automatically operate a
couple of times afte r the washer squirts.
Vehicles with headlight cleaners:
When the headlights are on and the lever is
pulled and held, the headlight cleaners will
operate once. After this, the headlight
cleaners will operate every 5th time the
lever is pulled.
■The windshield wipers and washer can
be operated when
The engine switch is in IGNITION ON
mode.
■Dripping prevention wiper sweep (vehi-
cles with rain-sensing windshield wip-
ers)
After washing and wiping operation several
times, the wipers operate one more time after a short delay to prevent dripping.
However, this function will not operate while
driving.
■Effects of vehicle speed on wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the Intermittent wiper
interval.
■Raindrop sensor (vehicles with rain-
sensing windshield wipers)
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc. are
present on the windshield.
●If the wiper switch is turned to the
position while the engine switch is in
IGNITION ON mode, the wipers will
operate once to show that AUTO mode
is activated.
●If the temperature of the raindrop sensor
is 194°F (90°C) or higher, or 5°F (-15°C)
or lower, automatic operation may not
occur. In this case, operate the wipers in
any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked, if there is washer fluid in the
washer fluid tank.

■Caution regarding the use of wind-
shield wipers in AUTO mode (vehi-

the windshield is subject to vibration in
AUTO mode. Take care that your fingers,
etc. do not become caught in the wind-
shield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE
■When the washer fluid tank is empty
Do not operate the switch continually as
the washer fluid pump may overheat.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other
object. The nozzle will be damaged.

2664-6. Driving tips
LEXUS NX300 Owners Manual_USA_M78389_en
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 front tires
*.
Ensure that all tires are the same size and
brand, and that chains match the size of the
tires.
*: Tire chains cannot be mounted on the
225/60R18 tires.
Snow tires should be used instead.
Perform the following according to the
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.
■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 LDA (Lane Departure
Alert with steering control) (if
equipped).
●Do not use LTA (Lane Tracing Assist)
(if equipped).
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.
