CAUTION
nThe ABS does not operate effectively when
lTires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
l The vehicle hydroplanes while driving at high speed on the wet or slick
road.
n Stopping distance when the ABS is ope rating on the wet or slick roads
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
l When driving on dirt, gravel or snow-covered roads
l When driving with tire chains
l When driving over bumps in the road
l When driving over roads with potholes or uneven roads
n Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS will not function correctly if different tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
n Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
n Pre-winter preparations
lUse fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
l Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
l 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.
nBefore driving the vehicle
Perform the following according to the driving conditions.
lDo not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to
melt the ice. Wipe away the water immediately to prevent it
from freezing.
l To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
l Remove any ice that has accumu lated on the vehicle chassis.
l Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

When driving
CAUTION
n
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or
serious injury.
lUse tires of the size specified for your vehicle.
l Maintain the recommended level of air pressure.
l Do not drive in excess of 75 mph (120 km/h) regardless of the type of
snow tires being used.
l Snow tires should be installed on all wheels.
n Driving with snow chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
lDo not drive in excess of the speed limit specified for the tire chains being
used or 30 mph (50 km/h), whichever is lower.
l Avoid driving on bumpy road surfaces or over potholes.
l Avoid sudden turns and braking.
l Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
NOTICE
nRepairing or replacing snow tires
Request repairs of and obtain replacement snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
n Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and trans-
mitter ID codes registered by your Toyota dealer.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
nWhen to replace your vehicle's tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
lA tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.

244 4-3. Do-it-yourself maintenance
nIf the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
nMaximum load of tire
Check that the maximum load of the replaced tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR) , see the Certification Label. (→P.
248, 341).
nTire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Sinc e summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 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 summer tires in highway driving.
3Snow tires For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally 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 regulations for possible restriction. Snow tires
should be installed on all wheels. ( →P. 141)

246 4-3. Do-it-yourself maintenance
CAUTION
nTire pressure warning system operation
The tire pressure warning system may not provide warning immediately
if a tire bursts or if sudden air leakage occurs.
nWhen inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may le ad to fatal or injury accidents.
lDo not mix tires of different makes, models, tread patterns or tread-
wear.
lDo not use tire sizes other than those recommended by Toyota.
lDo not mix radial, bias-belted, or bias-ply tires.
lDo not mix summer, all season and winter tires.
lDo not use tires that have been used on another vehicle.
lDo not use tires if you do not know how they were used previously.
