Maintenance of the tires
Each tire, including the spare (if provided ), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicl e has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).

Resetting the tire pressure warning data
After adjusting the tire inflation pressu re, be sure to initialize the data. ( P. 76 4 )
If the message remains on, the system ma y have malfunctioned. Have the vehicle
inspected by your Lexus dealer as soon as possible. ■
Warning message in vehicle-to-vehicle distance control mode of the dynamic
radar cruise control (if equipped)
In the following cases, the warning message may not be displayed even if vehicle-
to-vehicle distance decreases: ●
When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle ●
When the vehicle ahead is traveling at a very low speed ●
Immediately after cruise control speed is set ●
At the instant the accelerator pedal is depressed
NOTICE■
While the engine oil level warning is displayed
Continued engine operation with low engine oil will damage the engine.
