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 dealers or repairers or other duly
qualified and equipped professionals. 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 repair-
ers 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 profes-
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Toyota vehicles.
Does your vehicle need repair?
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, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condi-
tioning 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 driving straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal or clutch pedal
(vehicles with a manual transmission), pedal almost touches the floor, vehi-
cle 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.

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
Hybrid model: Make sure that the indicator on the power switch and the
“READY” indicator are both off.
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 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 discomfort, consult a doctor.
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
With the engine 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. 519)
Vehicles with a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 519)
Hybrid model:
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. 519)

Maintenance and care
CAUTION
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 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.

Maintenance and care
CAUTION
When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
When using a floor jack, follow the instructions of the manual provided with
the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the engine (except hybrid model) or hybrid system (hybrid
model) while the vehicle is supported by the floor jack.
Except hybrid model: Stop the vehicle on level firm ground, firmly set the
parking brake and shift the shift lever in P (Multidrive), E, M or R (multi-
mode manual transmission) or R (manual transmission).
Hybrid model: Stop the vehicle on level, firm ground, firmly set the parking
brake and shift the shift position to P.
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Do not raise the vehicle while someone is in the vehicle.
When raising the vehicle, do not place any object on top of or underneath
the floor jack.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.
