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
● Keep hands, clothing and tools away from the moving fans and en gine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right

● Do not leave anything that may burn easily, such as paper and r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a smart key system:
Be sure the engine switch is off.
With the engine switch in the “ON” position, the electric cooli ng fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. ( P. 527)
Vehicles with a smart key system:
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may

Maintenance and care
HIGHLANDER_U■
If the oil is spilled on the engine cover (vehicles with 3.5 L V6 [2GR-FKS]
engine)
To prevent the engine cover from being damaged, remove any engi ne oil
from the engine cover as soon as possible using a neutral deter gent. Do not
use an organic solvent such as brake cleaner.
WARNING
■ Used engine oil
● Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation and skin cancer, so c are
should be taken to avoid prolonged and repeated contact. To remove used
engine oil from your skin, wash thoroughly with soap and water.
● Dispose of used oil and filters only in a safe and acceptable manner. Do
not dispose of used oil and filters in household trash, in sewe rs or onto the
ground.
Call your Toyota dealer, service station or auto parts store fo r information
concerning recycling or disposal.
● Do not leave used engine oil within the reach of children.
NOTICE
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil

WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may resu lt in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
NOTICE
■Replacing tire pressure warn ing valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced b y your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work prop erly
with non-genuine wheels.
●Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death o r serious injury.
