Maintenance and care
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valves
and transmitters (except for compact spare tire) that allow the tire pressure
warning system to provide advance warning in the event of a los s in tire infla-
tion pressure. Whenever wheels are replaced, tire pressure warning valves
and transmitters must be installed. ( P. 618)
WARNING
■When replacing wheels
● Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may resu lt in a 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
● Be sure to install the wheel nuts with the tapered ends facing inward.
( P. 738) 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 dea th or serious
injury.
● 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, caus ing an acci-
dent and resulting in death or serious injury. Remove any oil o r grease
from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possi bly causing an
accident.

7387-2. Steps to take in an emergency
C-HR_HV_OM_Europe_OM10720E
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
Install the spare tire and loosely tighten each wheel nut by ha nd by
approximately the same amount.
When replacing an aluminum
wheel with a compact spare
tire, tighten the wheel nuts until
the tapered portion comes into
loose contact with the disc
wheel seat.
When replacing an aluminum
wheel with an aluminum wheel,
turn the wheel nuts until the
washers come into contact with
the disc wheel.
