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 serious 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
(except 195/50R19 tires)
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), 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.

4305-6. Driving tips
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 wind-
shield.
 Check for and remove any
excess ice or snow that may
have accumulated on the
exterior lights, outside rear
view mirrors, windows, vehi-
cle’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 suit-
able to road conditions.

Turn automatic mode of the
parking brake off.
Otherwise, the parking brake
may freeze and not be able to
be released automatically.
Also, avoid using the following as
the parking brake may operate
automatically, even if automatic
mode is off.
• Brake hold system
Park the vehicle and shift the
shift position to P without set-
ting the parking brake. The
parking brake may freeze up,
preventing it from being
released. If the vehicle is
parked without setting the
parking brake, make sure to
block the wheels. Failure to
do so may be dangerous
because it may cause the
vehicle to move unexpect-
edly, possibly leading to an
accident.
 When the parking brake is in
automatic mode, release the
parking brake after shifting
the shift position to P.
( P.264)
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from your Toyota
dealer 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.

Driving
If the vehicle is parked without
setting the parking brake,
confirm that the shift position
cannot be moved out of P.
 If the vehicle is left parked
with the brakes damp in cold
temperatures, there is a pos-
sibility of the brakes freezing.
Vehicles without 195/50R19
tires
Use the correct tire chain size
when mounting the tire chains.
Chain size is regulated for each
tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain: 0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
Vehicles with 195/50R19 tires
Tire chains cannot be mounted.
Snow tires should be used
instead.
Regulations regarding the use
of tire chains vary depending on
location and type of road.
Always check local regulations
before installing chains.
■Tire chain installation
Observe the following precautions
when installing and removing
chains:
●Install and remove tire chains in a
safe location.
●Install tire chains on the front tires
only. Do not install tire chains on
the rear tires.
●Install tire chains on front tires as
tightly as possible. Retighten
chains after driving 1/4 - 1/2 mile
(0.5 - 1.0 km).
●Install tire chains following the
instructions provid ed with the tire
chains.
WARNING
■When parking the vehicle
When parking the vehicle without
applying the parking brake, make
sure to chock the wheels. If you
do not chock the wheels, the vehi-
cle may move unexpectedly, pos-
sibly resulting in an accident.

■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are
showing on a tire.
●You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage
●A tire goes flat repeatedly or can-
not be properly repaired due to
the size or location of a cut or
other damage
If you are not sure, consult your
Toyota dealer.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.
■Low profile tires (vehicles with
195/50R19 tires)
Generally, low profile tires will wear
more rapidly and tire grip perfor-
mance will be reduced on snowy
and/or icy roads when compared to
standard tires. Be sure to use snow
tires on snowy and/or icy roads and
drive carefully at a speed appropri-
ate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2
of the Gross Axle Weight Ratings
(GAWR) of either the front axle or
the rear axle, whic hever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum
cold tire inflation pressure men-
tioned on the sidewall of the tire.
(  P.609)
■Tire types
●Summer tires
Summer tires are high-speed per-
formance tires best suited to high-
way driving under dry conditions.
Since summer tires do not have
the same traction performance as
snow tires, summer tires are inad-
equate for driving on snow-cov-
ered or icy roads. For driving on
snow-covered roads or icy roads,
the use of snow tires is recom-
mended. When installing snow
tires, be sure to replace all four
tires.
●All season tires
All season tires are designed to
provide better traction in snow and
to be adequate for driving in most
winter conditions as well as for
use year-round. All season tires,
however, do not have adequate
traction performance compared
with snow tires in heavy or loose
snow. Also, all season tires fall
short in acceleration and handling
performance compared with sum-
mer tires in highway driving.
●Snow tires
For driving on snow-covered
roads or icy roads, we recom-
mend using snow tires. If you
need snow tires, select tires of the
same size, construction and load
capacity as the originally installed
tires. Since your vehicle has radial
tires as original equipment, make
sure your snow tires also have
radial construction. Do not install
studded tires without first checking
local regulation s for possible
restrictions. Snow tires should be
installed on all wheels. ( P.429)

Maintenance and care
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initia lize the tire pres-
sure warning system after tire rota-
WARNING
■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of the drivetrain as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted
or bias-ply tires).
●Do not mix summer, all season
and snow tires.
●Do not use tires that have been
used on another vehicle.
Do not use tires if you do not
know how they were used previ-
ously.
NOTICE
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire in flation pressure,
reducing the cushioning ability of
the tires. In addition, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.
■Low profile tires (vehicles
with 195/50R19 tires)
Low profile tires may cause
greater damage than usual to the
tire wheel when sustaining impact
from the road surface. Therefore,
pay attention to the following:
●Be sure to use proper tire infla-
tion pressure. If tires are under-
inflated, they may be damaged
more severely.
●Avoid potholes, uneven pave-
ment, curbs and other road haz-
ards. Failure to do so may lead
to severe tire and wheel dam-
age.
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.
