4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors and remove the antenna before washing the vehicle.
Start washing from the front of the vehicle. Make sure to re-install the
antenna and extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
■ High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity
of the windows.
● Before car wash, check that the fuel filler door on your vehicle is closed
properly.
■ Bumpers and side moldings
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime
condition.
● Working from top to bottom, liber ally 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
car wash mitt.
● For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

Maintenance and care
CAUTION
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 manifold, 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 or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.

230 4-3. Do-it-yourself maintenance
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least
once a month.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure ma y result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your Scion dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be mi sleading. In addition, tire infla-
tion pressures that are even just a few pounds off can degrade ride
and handling.
●Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

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 tire 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.

Vehicle specifications
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can caus e heat buildup and possible tire fail-
ure.
