Repair and replacement

It is recommended that genuine

Toyota parts be used for repairs to

ensure performance of each sys-

tem. If non-Toyota parts are used in

replacement or if a repair shop other

than a Toyota dealer performs

repairs, confirm the warranty cover-

age.

■

Allow inspection and repairs to

be performed by a Toyota

dealer

●

Toyota technicians are

well-trained specialists and are

kept up to date with the latest ser-

vice information. They are well

informed about the operation of all

systems on your vehicle.

●

Keep a copy of the repair order. It

proves that the maintenance that

has been performed is under war-

ranty coverage. If any problem

should arise while your vehicle is

under warranty, your Toyota

dealer will promptly take care of it.

General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.

Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.

For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.

Engine oil consumption

A certain amount of engine oil will

be consumed while driving. In the

following situations, oil consump-

tion may increase, and engine oil

may need to be refilled in between

oil maintenance intervals.

●

When the engine is new, for

example directly after purchasing

the vehicle or after replacing the

engine

●

If low quality oil or oil of an inap-

propriate viscosity is used

●

When driving at high engine

speeds or with a heavy load, or

when driving while accelerating or

decelerating frequently

●

When leaving the engine idling for

a long time, or when driving fre-

quently through heavy traffic

■

Engine oil level rise

If the vehicle is repeatedly driven

without the engine warmed up,

moisture caused by dew condensa-

tion inside the engine or fuel which

did not burn mixes into the engine

oil, resulting in a rise in engine oil

level. However, this is not a mal-

function. For example, the engine

become difficult to be warmed up in

the following situations.

●

When driving a short distance

●

When driving at a low speed

●

When the outside temperature is

low

When checking the engine oil, make

sure that the engine is warmed up. If

the engine oil level exceeds the refill

upper limit mark, contact your Toy-

ota dealer.
