Where to go for maintenance service?
In order to maintain your vehicle in the highest possible condition, Toyota
recommends that all repairs and service operations be carried out by autho-
rized Toyota dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an
authorized Toyota dealer or repairer, who will use genuine Toyota parts in
repairing any difficulties you may encounter. There can also be advantages
in utilizing authorized Toyota dealers 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 dealer or repairer, or another duly qualified and equipped pro-
fessional service department 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 missing, st umbling 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 mon-
oxide 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 or clutch 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
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.

WARNING
■
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system: Be sure the engine switch is
off. With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( →P. 334)
Vehicles with a smart entry & start system: Be sure the “ENGINE START
STOP” switch is off. With the “ENG INE START STOP” switch in IGNITION
ON mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the cool ant temperature is high. (→P. 334)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the 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 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.

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to
check that the radiator cooling fans operate and to check for
coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are operating by
checking the fan sound and air flow. If it is difficult to check these,
turn the air conditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)

Toyota dealer or repairer, or another duly qualified and
equipped professional.
If the fans are operating: Have the vehicle inspected at the nearest authorized
