When trouble arises
When replacing tires on a vehi-
cle with wheel lock nuts, use the
following procedures to remove
and install the wheel lock nuts.
The wheel lock key is stored
together with the tools on the right-hand side of the luggage
compartment. Always return the
wheel lock key to its original
position after use, so that it does
not get lost.
■Removal
For ease of removal, the wheel
lock nut should always be the
first one loosened.
1 Place the wheel lock key on
top of the wheel lock nut,
turning until the wheel lock
key and wheel lock nut pat-
terns engage.
2 Place the wheel nut wrench
on the wheel lock key, and
while applying pressure on
the wheel lock key, loosen
the wheel lock nut.
■Installation
For ease of installation, the
wheel lock nut should always be
the last one tightened.
1 By hand, install a wheel lock
nut on each wheel.
2 Place the wheel lock key on
top of the wheel lock nut,
turning until the wheel lock
key and wheel lock nut pat-
terns engage.
3 Place the wheel nut wrench
on the wheel lock key, and
while applying pressure on
the wheel lock key, tighten
the wheel lock nut to the rec-
ommended torque.
WARNING

and the wheel nut wrench as
shown in the illustration.
5 Raise the vehicle until the tire
is slightly raised off the

WARNING
■Replacing a flat tire
●Observe the fo
llowing precau-
tions. Failure to do so may
result in serious injury.
• Do not touch the disc wheels or the area around the brakes
immediately after the vehicle
has been driven. After the vehi-
cle has been driven the disc
wheels and the area around the
brakes will be extremely hot.
Touching these areas with
hands, feet or oth er body parts
while changing a tire, etc. may
result in burns.
• Remove the spare tire before jacking up the vehicle. If the
spare tire is removed after jack-
ing up the vehicle, the tire car-
rier and the spare tire may
interfere with the jack and cause
a serious accident.
●Failure to follow these precau-
tions could cause the wheel
nuts to loosen and the tire to fall
off, resulting in death or serious
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.
