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

cle. Do not use your spare tire on another vehicle. ●
Do not use more than one spare tires simultaneously. ●
Replace the spare tire with a stan dard tire as soon as possible.●
Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations
that cause sudden engine braking. ■
When the spare tire is attached
The vehicle speed may not be correctly detected, and the following systems may not
operate correctly:
Also, not only can the following system not be utilized fully, but it may even negatively
affect the drive-train components:
• AWD system (if equipped) ■
Speed limit when using the spare tire
Do not drive at speeds in excess of 50 mp h (80 km/h) when a spar e tire is installed on
the vehicle.
The spare tire is not designed for driving at high speeds. Fa ilure to observe this precau-
tion may lead to an accident causing death or serious injury. ■
After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their storage
location to reduce the possibilit y of personal injury during a collision or sudden brak-
ing.
NOTICE ■
Driving with tire chains and the spare tire
Do not fit tire chains to the spare tire.
Tire chains may damage the vehicle body and adversely affect driving performance.■
When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and trans-
mitter, contact your Lexus dealer as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.• ABS & Brake assist
