Driving
COROLLA_U
4-6.Driving tips
Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician
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
WA R N I N G
■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. (if equipped)
●Do not use LDA (Lane Depar-
ture Alert with steering control)
system. (if equipped)
NOTICE
■Repairing or replacing snow
tires (vehicles with a tire pres-
sure warning system)
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.

4527-1. Maintenance and care
COROLLA_U
7-1.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.126)
■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
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
■Plated portions
If dirt cannot be re moved, clean the
parts as follows:

ner appropriate to each

WA R N I N G
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 a fter 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 battery. Fuel and battery
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 fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.471)
■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 ai r cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

4867-3. Do-it-yourself maintenance
COROLLA_U
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels (vehi-
cles with a tire pressure warn-
ing system)
The wheels of your vehicle are
equipped with tire pressure warning
valves and transmit ters that allow
the tire pressure warning system to
provide advance warning in the
event of a loss in tire inflation pres-
sure. Whenever wheels are
replaced, the tire pressure warning
valves and transmitters must be
installed. ( P.480)
Wheels
If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.
Wheel selection
WA R N I N G
■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
●Be sure to install the wheel nuts
with the tapered ends facing
inward.(P.539) Installing the
nuts with the tapered ends fac-
ing outward can cause the
wheel to break and eventually
cause the wheel to come off
while driving, wh ich could lead
to an accident resulting in death
or serious injury.
●Never use oil or grease on the
wheel bolts or wheel nuts.
Oil and grease may cause the
wheel nuts to be excessively
tightened, 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 fr om the wheel
bolts or wheel nuts.
■Use of defective wheels pro-
hibited
Do not use cracke d or deformed
wheels. Doing so could cause the
tire to leak air during driving, pos-
sibly causing an accident.
