Driving
Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine/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.
Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner 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 m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the size specified.
●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 specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing 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.
●Do not use LDA (Lane Depar-
ture Alert) system.
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers 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.

3026-1. Maintenance and care
6-1.Maintenance and care
Working from top to bottom,
liberally 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
thoroughly with water.
 Wipe away any water.
 Wax the vehicle when the
waterproof coating deterio-
rates.
If water does not bead on a clean
surface, apply wax when the vehi-
cle body is cool.
■Automatic car washes
●Fold the mirrors before washing
the vehicle. Start washing from the
front of the vehicle. Make sure to
extend the mirrors before driving.
●Brushes used in automatic car
washes may scratch the vehicle
surface, parts (wheel, etc.) and
harm your vehicle’s paint.
●Vehicles with a rear spoiler: In cer-
tain automatic car washes, the rear spoiler may interfere with
machine operation. This may pre-
vent the vehicle from being
cleaned properly or result in dam-
age to the r
ear spoiler.
■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 these
areas continuously.
■When using a car wash (vehi-
cles with a smart key system)
If the door handle becomes wet
while the electronic key is within the
effective range, the door may lock
and unlock repeatedly. In that case,
follow the following correction pro-
cedures to wash the vehicle:
●Place the key in a position 6 ft. (2
m) or more separate from the
vehicle while the vehicle is being
washed. (Take care to ensure that
the key is not stolen.)
●Set the electronic key to bat-
tery-saving mode to disable the
smart key system. ( P.137)
■Wheels and wheel ornaments
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the
wheels when they are hot, such
as after driving or parking in hot
weather
■Brake pads and calipers
Rust may form if the vehicle is
parked with wet brake pads or disc
rotors, causing them to stick. Before
parking the vehicle after it is
washed, drive slo wly and apply the
brakes several times to dry the
Cleaning and protect-
ing the vehicle exte-
rior
Perform cleaning in a man-
ner appropriate to each
component and its material.

WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-inform ation display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fans.
ItemsParts and tools●Be careful not to touch the
engine, power control unit, radi-
ator, 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 compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the 12-volt battery. Fuel and
12-volt battery fumes are flam-
mable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
■When working near the elec-
tric cooling fans or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fans may auto-
matically start to r un if the air con-
ditioning is on an d/or the coolant
temperature is high. ( P.321)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting 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.

Maintenance and care
Use only Toyota wheel nuts
and wheel nut wrenches
designed for use with your
aluminum wheels.
 When rotating, repairing or
changing your tires, check
that the wheel nuts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels.
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended in the Owner’s Manual,
as this may result in a loss of
handling control.
●Never use an inner tube in a
leaking wheel which is designed
for a tubeless tire.
Doing so may result in an acci-
dent, causing death or serious
injury.
■When installing the wheel
nuts
Never use oil or grease on the
wheel bolts or wheel nuts.
Oil and grease may cause the
wheel nuts to be excessively tight-
ened, leading 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 an accident and
resulting in death or serious injury.
Remove any oil or grease from
the wheel bolts or wheel nuts.
■Use of defective wheels pro-
hibited
Do not use cracked or deformed
wheels. Doing so could cause the
tire to leak air during driving, pos-
sibly causing an accident.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.

WARNING
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the r eplacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
NOTICE
■To ensure the tire pressure
warning system operates
properly
Do not install tires with different
specifications or makers, as the
tire pressure warning system may
not operate properly.
If a war ning message
