WA R N I N G
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
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.

4887-3. Do-it-yourself maintenance
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
 When rotating, repairing or
changing your tires, check that
the wheel nuts ar e still tight after
driving 1600 km (1000 miles).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
WA R N I N G
●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 grease can cause the wheel nuts to
loosen and the wheel may fall off,
causing an accident and resulting in
death or serious injury. Remove any oil or grease from the wheel bolts or
wheel nuts.
■Use of defective wheels prohib-
ited
Do not use cracked or deformed wheels. Doing so could cause the tire
to leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters (vehicles
with a tire pressure warning sys-
tem)
●Because tire repair or replacement
may affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. In addition, make sure to
purchase your tire pressure warn-
ing valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
●Ensure that only genuine Toyota
wheels are used on your vehicle. Tire pressure warning valves and
transmitters may not work properly
with non-genuine wheels.

The engine oil level is low. Check the
WA R N I N G
●Vehicles with a compact spare tire
and full-size spare tire: If the tire
pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you
have a flat tire. Check the tires. If a tire is flat, change it with the spare
tire and have the flat tire repaired
by the nearest any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: If the tire pressure
warning light comes on even after
tire inflation pressure adjustment, it is probable that you have a flat tire.
Check the tires. If a tire is flat, repair
the flat tire by using emergency tire puncture repair kit.
●Avoid abrupt maneuvering and braking.
If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leak-age should occur (vehicles with
a tire pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warn-
ing system operates properly
(vehicles with a tire pressure warning system)
Do not install tires with different speci-
fications or makers, as the tire pres- sure warning system may not operate
properly.
If a war ning message is
displayed
The multi-information display
shows warnings for system
malfunctions and incorrectly
performed operations, and
messages that indicate a need
for maintenance. When a mes-
sage is displayed, perform the
appropriate corrective action
for the message.
If a warning message is dis-
played again after the appro-
priate actions have been
performed, contact any author-
ized Toyota retailer or Toyota
authorized repairer, or any reli-
able repairer.
Additionally, if a warning light
comes on or flashes at the
same time that a warning mes-
sage is displayed, take the
appropriate corrective action
for the warning light. ( P.511)

5228-2. Steps to take in an emergency
• “Smart Entry & Start System Malfunc-
tion”
●If any of the following messages are
displayed on the multi-information dis- play, it may indicate a malfunction.
Immediately stop the vehicle and con-
tact any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
• “Braking Power Low” • “Charging System Malfunction”
• “Oil Pressure Low”
NOTICE
■If “High Power Consumption Par-
tial Limit on AC/Heater Opera- tion” is displayed frequently
There is a possible malfunction relat-
ing to the charging system or the bat- tery may be deteriorating. Have the
vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
If you have a flat tire
(vehicles with an emer-
gency tire puncture
repair kit)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
Depending on the damage, this
kit cannot be used to repair the
tire. ( P.523)
After temporarily repairing the
tire with the kit, have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer. Repairs
conducted using the emer-
gency tire puncture repair kit
are only a temporary measure.
Have the tire repaired and
replaced as soon as possible.
