Maintenance and care
AVENSIS_EE (OM20B44E)
CAUTION
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 loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
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 tightened,
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 acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
Be sure to install the wheel nuts with
the tapered ends facing inward. Install-
ing the nuts with the tapered ends fac-
ing 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 or
serious injury.Tapered

wheel beyond repair.
When performing an emergency repair
Perform the emergency repair without removing the nail or screw that has
punctured the tread of the tire. If the object that has punctured the tire is
removed, the repair using the sealant in the emergency tire puncture repair
kit may fail.
When fixing the flat tire

Store it in a clean place.
Do not remove the inside cap of the sealant bottle.
Turn the valve core tool with your hand when screwing it in. If you use
another tool in conjunction with the valve core tool, damage may occur.
Do not operate the compressor continuously for more than 7 minutes. The
motor may overheat and be damaged. Let the compressor cool before
using it again.
Compressor precautions
The compressor power source should be 12 V DC suitable for vehicle use.
Do not connect the compressor to 24 V DC or any other power source.
The compressor is an oil-less type. Do not lubricate with oil.
