■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 valve 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 warning 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.

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 spare tire is installed on
the vehicle.
The spare tire is not designed for driving at high speeds. Failure 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
