WARNING
● Do not place anything on the luggage cover. In the event of sudden brak-
ing or turning, the item may go flying and strike an occupant. This could
lead to an unexpected accident, resulting in death or serious injury.
● Do not allow children to climb on the luggage cover. Climbing on the lug-
gage cover could result in damage to the luggage cover, possibly causing
death or serious injury to the child.
● Make sure that the rear edge of the cover is laying flat. If the cover is
installed with the rear edge raised, t he view from the rear window may be
obstructed, which could cause an accident.
● Make sure that seat belts are not caught up in the luggage cover. If a seat
belt is caught up in the cover, it may not be able to restrain passengers
properly.

In the following conditions, it may not operate correctly
● The portable device is fully charged
● There is foreign matter between the charge area and portable device
● The temperature of the portable device gets higher from charging
● The charging surface of the portable device is facing up
● The placement of the portable device is out of alignment with the charge
area
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that gener ates strong radio waves or electrical
noise
● When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal

already in the engine.
Make sure to check the oil type and prepare the items needed
before adding oil.
Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.

A certain amount of engine oil will be consumed while driving. In the following
situations, oil consumption 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 inappropriate viscosity is used

Maintenance and care
■Situations in which the tire pressure warning system may not operate
properly (if equipped)
●In the following cases, the tire pressure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• When a replacement tire is used, the system may not operate correctly
due to the structure of the replacement tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without the tire pressure warning valve and transmitter is used.
• If the ID code on the tire pressure warning valves and transmitters is not
registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
• When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

Maintenance and care
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident resulting
in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
● Vehicles with an emergency tire puncture repair kit: Do not tow anything if
a tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.
■ When initializing the tire pressure warning system (if equipped)
Do not initialize the tire pressure wa rning system without first adjusting the
tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.
