■Where to go for the maintenance service?
In order to maintain your vehicle in the best possible condition, Toyota recom-
mends that all repairs and service operations be carried out by authorized
Toyota retailers or repairers or other duly qualified and equipped profession-
als. For repairs and services covered by your warranty, please visit an autho-
rized Toyota retailer 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 Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer will
perform all of the scheduled maintenance on your vehicle reliably and eco-
nomically 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 misfire, 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
If you notice any of these clues, take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as pos-
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 el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Vehicles without a smart entry & start system: Make sure that the power
switch is in the “LOCK” position and the “READY” indicator are off.
● Vehicles with a smart entry & start system: Make sure that the “Power on”
on the multi-information 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. Fuel fumes
are flammable.
● 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 discomfort, consult a doctor.
■ When working near the electric cooling fan or radiator grille
Vehicles without a smart entry & start system
Be sure the power switch is in the “LOCK” position.
With the power switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 443)
Vehicles with a smart entry & start system
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fan may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 443)

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 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.
