RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and the
tire. When resting the tire on the ground,
place the tire so that the wheel design
faces up to avoid scratching the wheel
surface. 4

WARNING ■
Replacing a flat tire ●
Do not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will
be extremely hot. Touching these areas with hands, feet or other body parts while
changing a tire, etc. may result in burns. ●
Failure to follow these precautions could cau se the wheel nuts to loosen and the tire
to fall off, 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, 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 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.
• Do not attach a heavily damaged wheel or nament, as it may fly off the wheel while
the vehicle is moving.
• 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.

500 7-2. Steps to take in an emergency
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)Firmly tighten each wheel nut two or
three times in the order shown in the
illustration. Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools. ■
The spare tire ●
RC350/RC300:
The spare tire is identified by the label “TEMPORARY USE ONLY” on the tire sidewall.●
Use the spare tire temporarily , and only in an emergency.●
Make sure to check the tire inflat ion pressure of the spare tire. (  P. 548)■
When using the spare tire
As the spare tire is not equipped with a tire pressure warning valv e and transmitter, low
inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warn ing light comes on, the
light remains on. ■
When the spare tire is equipped
The vehicle becomes lower when driving with the spare tire compared to when driving
with standard tires. ■
If you have a flat rear tire on a road covered with snow or ice (vehicles with front and
rear tires of the same size except fo r vehicles with LDH and 19-inch tires)
Install the spare tire on one of the front whee ls of the vehicle. Perform the following steps
and fit tire chains to the rear tires:
Replace a front tire with the spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires. 4
