WARNING

■

To prevent vehicle damage or vehicle fire

●

Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air intake vent, and in the luggage com-
partment.
Doing so may cause the hybrid battery (traction battery), electrical compo-
nents, etc., to malfunction or catch fire.

●

Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.

stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.

■

Water on the floor

Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.

6-2. Maintenance

Maintenance requirements

Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.

For full details of your maintenance schedule, refer to the “Toyota Service
Booklet” or “Toyota Warranty Booklet”.

What about do-it-yourself maintenance?

Many  maintenance  items  are  easy  to  do  yourself  if  you  have  a  little
mechanical ability and a few basic automotive tools.
Note,  however,  that  some  maintenance  tasks  require  special  tools  and
skills. These are best performed by qualified technicians. Even if you’re an
experienced  do-it-yourself  mechanic,  we  recommend  that  repairs  and
maintenance  be  conducted  by  any  authorized  Toyota  retailer  or  Toyota
authorized repairer, or any reliable repairer. Any authorized Toyota retailers
or repairer will keep a record of maintenance, which could be useful should
you ever require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Toyota repairer to ser-
vice  or  maintain  your  vehicle,  we  recommend  that  you  request  that  a
record of maintenance be kept.

To ensure safe and economical driving, day-to-day care and reg-
ular maintenance are essential. Toyota recommends the follow-
ing maintenance:

Where to go for maintenance service?

In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Toyota retailers or repairers or other duly
qualified  and  equipped  professionals.  For  repairs  and  services  covered  by
your warranty, please visit an authorized Toyota retailers or repairer, who will
use  genuine  Toyota  parts  in  repairing  any  difficulties  you  may  encounter.
There  can  also  be  advantages  in  utilizing  authorized  Toyota  retailers  or
repairers  for  non-warranty  repairs  and  services,  as  members  of  the Toyota
network  will  be  able  to  expertly  assist  you  with  any  difficulties  you  may
encounter.
Your authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Toyota vehicles.

Does your vehicle need repairs?

Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:

●

Engine misses, stumbling or pinging

●

Appreciable loss of power

●

Strange engine noises

●

A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)

●

Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked
immediately.)

●

Flat-looking tires, excessive tire squeal when cornering, uneven tire wear

●

Vehicle pulls to one side when driven straight on a level road

●

Strange noises related to suspension movement

●

Loss of brake effectiveness, spongy feeling brake pedal, pedal almost
touches the floor, vehicle pulls to one side when braking

●

Engine coolant temperature continually higher than normal (

sible. Your vehicle may need adjustment or repair.

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

●

Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-infor-
mation display and the “READY” indicator are both off.

●

Keep hands, clothing and tools away from the moving fan.

●

Be careful not to touch the engine, power control unit, 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 and rags, in the
engine compartment.

●

Do not smoke, cause sparks or expose an open flame to fuel or the 12-volt
battery. Fuel and 12-volt battery fumes are flammable.

●

Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.

●

Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experience discom-
fort, consult a doctor.

■

When working near the electric cooling fans or radiator grille

Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (

P. 604)

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.

■

If the brake fluid level is low or high

It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

WARNING

■

Pre-driving check

Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.

■

After installing the support rod into the slot

Make sure the rod supports the hood securely preventing it from falling
down onto your head or body.

NOTICE

■

When closing the hood

Be sure to return the support rod to its clip before closing the hood. Closing
the hood without returning the support rod properly could cause the hood to
bend.
