injury.
●Have the wheel nuts tightened with a torque wrench to 76 ft·lbf (103
N·m, 10.5 kgf·m) as soon as possible after changing wheels.

Maintenance and care
CAUTION
■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
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
■Location of tools
There are no place to install the jack, wheel nut wrench and wheel
chocks, so do not put it inside the vehicle.
Failure to follow the precaution could cause the interior to get damaged,
the tools may fly out in events such as sudden braking, and may cause
an accident.
●Be sure to install the wheel nuts with
the tapered end faci
ng inward. Install-
ing the nuts with the tapered end fac-
ing outward can cause wheel to
break and eventually cause a wheel
to come off while driving, which could
lead to an accident resulting in death
or serious injury.Tapered
