inspect the condition of the 
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 may 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 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. (if equipped)
●Do not use LDA (Lane Depar-
ture Alert with steering control) 
system. (if equipped)
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.

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
●Keep hands, clothing and tools 
away from the moving fan and 
engine drive belt.
●Be careful not to touch the 
engine, radiator, exhaust mani-
fold, 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. 
Fuel fumes are flammable.
ItemsParts and tools●Be extremely cautious when 
working on the battery. It con-
tains poisonous and corrosive 
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator 
grille
Be sure the engine switch is off.
With the engine switch in ON, the 
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant 
temperature is high. ( P.438)
■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.

WARNING
■When adding washer fluid
Do not add washer fluid when the 
engine is hot or running as 
washer fluid contains alcohol and 
may catch fire if spilled on the 
engine, etc.
NOTICE
■Do not use any fluid other 
than washer fluid
Do not use soapy water or engine 
antifreeze instead of washer fluid.
Doing so may cause streaking on 
the vehicle’s painted surfaces, as 
well as damaging the pump lead-
ing to problems of the washer 
fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as 
necessary.
Refer to the freezing tempera-
tures listed on the label of the 
washer fluid bottle.

Maintenance and care
etc., molded into the sidewall of 
each tire.
Replace the tires if the treadwear 
indicators are showing on a tire.
■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 with 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 (18-inch 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 or tire chains on snowy and/or 
icy roads and drive carefully at a 
speed appropriate 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 mentioned on 
the sidewall of the tire. ( P.524)
■Tire types
●Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway 
driving under dry conditions. Since 
summer tires do not have the same 
traction performance as snow tires, 
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 install-
ing snow tires, be sure to replace all 
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to 
be adequate for driving in most win-
ter conditions as well as for use 
year-round. All season tires, how-
ever, do not have adequate traction 
performance compared with snow 
tires in heavy or loose snow. Also, 
all season tires fall  short in accelera-
tion and handling performance com-
pared with summer tires in highway 
driving.
●Snow 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 
originally installed tires. Since your 
vehicle has radial tires as original 
equipment, make sure your snow  
Page 444 of 576

4447-3. Do-it-yourself maintenance
COROLLA H/B_Utires also have radial construction. 
Do not install studded tires without 
first checking local regulations for 
possible restrictions. Snow tires 
should be installed on all wheels. 
(
 P.251)
■If the tread on snow tires wears 
down below 0.16 in. (4 mm)
The effectiveness of the tires as 
snow tires is lost.
■Checking the tire valves
When replacing the tires, check the 
tire valves for deformation, cracks, 
and other damage.
Rotate the tires in the order 
shown.
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 drive train 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
■Low profile tires (18-inch 
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.
■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.

Maintenance and care
Front
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 initialize the tire pres-
sure warning system after tire rota-
tion.
Your vehicle is equipped with a 
tire pressure warning system 
that uses tire pressure warning 
valves and transmitters to detect 
low tire inflation pressure before 
serious problems arise.
If the tire pressure drops below 
a predetermined level, the driver 
is warned by a warning light. 
( P.476)
■Routine tire inflation pressure 
checks
The tire pressure warning system 
does not replace routine tire inflation 
pressure checks. Make sure to 
check tire inflation pressure as part 
of your routine of daily vehicle 
checks.
■Situations in which the tire 
pressure warning system may 
not operate properly
●In the following cases, the tire 
pressure warning system may not 
operate properly.
• If non-genuine Toyota wheels are  used.
• A tire has been replaced with a  tire that is not an OE (Original 
Equipment) tire.
• A tire has been replaced with a  tire that is not of  the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-sup ported run-flat tire 
is equipped.
• If a window tint that affects the 
radio wave signals is installed.
• If there is a lot of snow or ice on  the vehicle, particularly around the 
wheels or wheel housings.
• If the tire inflation pressure is  extremely higher than the speci-
fied level.
• If tires not equipped with tire pres- sure warning valv es and transmit-
ters are used.
• If the ID code on the tire pressure  warning valves and transmitters is 
not registered in the tire pressure 
warning computer.
●Performance may be affected in 
the following situations.
• Near a TV tower, electric power 
plant, gas station, radio station, 
large display, airport or other facil-
ity that generates strong radio 
waves or electrical noise.
• When carrying a portable radio,  cellular phone, cordless phone or 
other wireless communication 
device.
●When the vehicle is parked, the 
time taken for the warning to start 
or go off could be extended.
●When tire inflation pressure 
declines rapidly for example when 
a tire has burst, the warning may 
not function.

■Warning performance of the tire 
pressure warning system
The warning of the tire pressure 
warning system will change in 
accordance with driving conditions. 
For this reason, the system may  give a warning even if the tire pres-
sure does not reach a low enough 
level, or if the pressure is higher 
than the pressure that was adjusted 
to when the system was initialized.
