5-6.Driving tips
 Use fluids that are appropriate to
the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Power control unit coolant
• Washer fluid
 Have a service technician
inspect the condition of the 12-
volt 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
vehicles with 235/55R19 tires.
Winter driving tips
Carry out the necessary prepa -
rations and inspections before
driving the vehicle in winter.
Always drive the vehicle in a
manner appropriate to the pre -
vailing weather conditions.
Pre-winter preparations
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 serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive at speeds in excess of the speed limit or the speed limit
specified for the snow tires being
used.
●Use snow tires on all, not just some
wheels.
■Driving with tire chains (except
235/55R19 tires)
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehi - cle 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 50 km/h (30 mph),
whichever is lower.
●Avoid driving on bumpy road sur -
faces or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shift-
ing operations that cause sudden engine braking.
●Slow down sufficiently before enter - ing a curve to ensure that vehicle
control is maintained.
●Do not use LTA (Lane Tracing
Assist) system (if equipped).
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer or legitimate tire retailers.
This is because the removal and
attachment of snow tires affects the operation of the tire pressure warning
valves and transmitters.

4887-1. Maintenance and care
7-1.Maintenance and care
Working from top to bottom, lib-
erally apply water to the vehicle
body, wheel wells and underside
of the vehicle to remove any dirt
and dust.
 Wash the vehicle body using a
sponge or soft cloth, such as a
chamois.
 For hard-to-remove marks, use
car wash soap and rinse thor -
oughly with water.
 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean sur -
face, apply wax when the vehicle body
is cool.
■Before car washes
Check that the fuel filler door and charging port lid on your vehicle are
closed properly.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from t he front of the vehi-
cle. Make sure to extend the mirrors
before driving.
●Brushes used in automatic car
washes may scratch the vehicle sur - face, parts (wheel, etc.) and harm
your vehicle’s paint.
●Rear spoiler may not be washable in
some automatic c ar washes. There
may also be an increased risk of dam - age to vehicle.
■High pressure car washes
As water may enter the cabin, do not
bring the nozzle tip near the gaps around the doors or perimeter of the
windows, or spray th ese areas continu-
ously.
■Note for a smart e ntry & start sys- tem
If the door handle becomes wet while
the electronic key is within the effective range, the door may lock and unlock
repeatedly. In that c ase, follow the fol-
lowing correction procedures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed.
(Take care to ensur e that the key is not stolen.)
●Set the electronic key to battery-sav - ing mode to disable the smart entry &
start system. ( →P.224)
■Wheels and wheel ornaments
●Remove any dirt immediately by using
a neutral detergent.
●Wash detergent of f with water imme-
diately after use.
●To protect the paint from damage,
make sure to observe the following
precautions. • Do not use acidic, alkaline or abrasive
detergent.
• Do not use hard brushes.
• Do not use deterg ent on the wheels when they are hot, such as after driv -
ing or parking in hot weather.

Cleaning instructions

4907-1. Maintenance and care
WARNING
■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
malfunction. If this occurs, consult any authorized Toyo ta retailer or
Toyota authorized repairer, or any
reliable repairer.
NOTICE
■To prevent paint deterioration and corrosion on the body and
components (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, insect droppings or
bird droppings are present on the
paint surface
• After driving in an area contami - nated with soot, o ily smoke, mine
dust, iron powder or chemical sub -
stances
• If the vehicle becomes heavily
soiled with dust or mud
• If liquids such as benzene and gas - oline are spilled on the paint sur-
face
●If the paint is chipped or scratched,
have it repaired immediately.
●To prevent the wh eels from corrod-
ing, remove any dirt and store in a
place with low humidity when stor - ing 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 off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper
blades may be damaged.
■When using a high pressure car
wash
●When washing the vehicle, do not let water from the high-pressure
washer directly hit the camera (if
equipped) or the area around the camera. Due to the shock from the
high pressure water, it is possible
that the device may not operate normally.
●Do not bring the no zzle tip close to boots (rubber o r resin manufac-
tured cover), or co nnectors or the
following parts. The parts may be damaged if they
come into contact with high-pres -
sure water.
• Traction battery
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi -
cle body. Otherwis e resin section,
such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously hold the
nozzle in the same place.
