3647-2. Steps to take in an emergency
When replacing tires on a vehicle with 
wheel lock nuts, use the following pro-
cedures to remove and install the 
wheel lock nuts. The wheel lock key is 
stored in the tray inside 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 loos-
ened.
1 Place the wheel lock key on top of 
the wheel lock nut, turning until the 
wheel lock key and wheel lock nut 
patterns 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 tight-
ened.
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 
patterns 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 
recommended torque.
1 Open the trunk.
2 Pull the lever upwards when lifting 
the luggage mat up.
WARNING
●Do not start the engine or drive the 
vehicle while the vehicle is supported 
by the jack.
●Do not raise the vehicle while some-
one is inside.
●When raising the vehicle, do not put an 
object on or under the jack.
●Do not raise the vehicle to a height 
greater than that required to replace 
the tire.
●Use a jack stand if it  is necessary to get 
under the vehicle.
●When lowering the vehicle, make sure 
that there is no-one near the vehicle. If 
there are people nearby, warn them 
vocally before lowering.

NOTICE
Do not use an impact wrench. Using an 
impact wrench may cause permanent 
damage to wheel lock nut and wheel lock 
key. If in doubt about wheel lock applica-
tion, contact your Lexus dealer.

When trouble arises
1Remove any dirt or foreign matter 
from the wheel contact surface.
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.
2
Install the spare tire and loosely 
tighten each wheel nut by hand by 
approximately the same amount.
Tighten the wheel nuts until the tapered 
portion   comes into loose contact with 
the disc wheel seat  .
3Lower the vehicle.
4 Firmly tighten each wheel nut two 
or three times in the order shown in 
the illustration.
Tightening torque:
WARNING
●Failure to follow these precautions 
could cause the wheel nuts to loosen 
and the tire to fall of f, resulting in death 
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 tightened, lead-
ing 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 a serious accident.
Remove any oil or grease from the 
wheel bolts or wheel nuts.
• 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.
• When installing a tire, only use wheel  nuts that have been specifically 
designed for that wheel.
• If there are any cracks or deformations  in the bolt screws, nut threads or bolt 
holes of the wheel, have the vehicle 
inspected by your  Lexus dealer.
• Do not attach a heavily damaged  wheel ornament, as it may fly off the 
wheel while the vehicle is moving.
