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.
 Prewinter preparations
 Use fluids that are appropriate to the prevailing outside tem−
peratures.
Engine oil
Engine coolant
Washer fluid
 Have a service technician inspect the level and specific grav−
ity of battery electrolyte.
Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
 Before driving the vehicle
Perform the following according to the driving conditions.

Do 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.
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.

When driving
CAUTION
 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.
 Use tires of the size specified for your vehicle.
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.
 Snow tires should be installed on all wheels.
4WD models:
Do not mix tires of different makes, models, tread patterns or treadwear.
 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.
 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 turns and braking.

Slow down sufficiently before entering a curve to ensure that vehicle con−
trol is maintained.
NOTICE
 Repairing 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.
 Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

288 4−3. Do−it−yourself maintenance
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,
sensor ID codes must be registered in the tire pressure warning com−
puter.
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.
If the ID code is not registered , the system will not work properly.
After about 20 minutes, the tire pressure warning light comes on after
blinking for 1 minute to indicate a system malfunction.
When to replace your vehicle’s tires
Tires should be replaced if:
You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
A 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.
Tire 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.
If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.

Maintenance and care
Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
Maximum load of tire
Check that the maximum load of the re placed 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. 292, 363, 375).
Tire types
1 Summer tires
Summer tires are high−speed performance tires best suited to highway
driving under dry conditions. Since 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 prov ide 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. (

Maintenance and care
CAUTION
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately
if a tire bursts or if
sudden air leakage occurs.
When 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.
Do not mix tires of different makes, models, tread patterns or tread−
wear.
Do not use tire sizes other than those recommended by Toyota.
Do not mix radial, bias−belted, or bias−ply tires.
Do not mix summer, all season and winter 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 previously.
NOTICE
Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
Do not use puncture sealant sprays to repair flats
Puncture sealant sprays may damage tire pressure warning valves and
transmitters.
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot−
holes.
These conditions may cause losses in tire inflation 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.
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Wheels
When replacing wheels
The wheels of your Toyota are equipped with sensors that allow the tire
pressure warning system sensors to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valve and transmitter must be switched over
from the old wheels. (
P. 288) If a wheel is bent, cracked or heavily corroded, it should be
replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
 Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and offset.
Replacement wheels are available at your Toyota dealer.
Toyota does not recommend using:

Wheels of different sizes or types
Used wheels

Bent wheels that have been straightened

Aluminum wheel precautions (if equipped)
Use only Toyota wheel nuts and wrench 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 balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
CAUTION
When replacing wheels
Do not use wheels that are a different size from those recommended in
the Owner ’s Manual, as this may result in 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 accident, causing death or seri−
ous injury.
NOTICE
Replacing tire pressure warning valves and transmitters
Because tire repair or replacement may affect the tire pressure warn−
ing valves and transmitters, make su re 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 transmitters at your
Toyota dealer.
Ensure that only Genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non−genuine wheels.

338 5−2. Steps to take in an emergency
CAUTION
Maintenance of the tire
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ−
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pr
essure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS−ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under−inflated. Accordingly,
when the low tire pressu
re telltale (tire pressure warning light) illumi−
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under−
inflated tire causes the tire to overheat and can lead to tire failure.
Under−inflation also reduces fuel effi
ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub−
stitute for proper tire main tenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under−inflation has not reached the
level to trigger illu
mination of the TPMS low ti re pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat−
ing properly. The TPMS (tire pressure warning system) malfunction indi−
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det
ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi−
nated. This sequence will
continue upon subsequent vehicle start−ups as
long as the malfunction exists. When the malfunction indi cator is illumi−
nated, the system may not be able to detect or signal low tire pressure
as intended.
