■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recomm ended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la bel (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 [tire and load in formation label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when on e or more of your tires is significantly
under-inflated. Accordingly, when the low ti re pressure telltale (tire pressure 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 ma y affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure wa rning system) is not a substitute for proper
tire maintenance, and it is the driver’s resp onsibility to maintain correct tire pressure,
even if under-inflation has no t reached the level to trigger illumination of the TPMS low
tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS
(tire pressure warning system) malfunction indi cator is combined with the low tire pres-
sure telltale (tire pressure warning light). When the system detects a malfunction, the
telltale will flash for approximately one minu te and then remain continuously illumi-
nated. This sequence will cont inue upon subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfun ctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning syst em) malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressure warning system) to continue to function
properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specificatio ns or makers, as the tire pressure warning
system may not operate properly.

*: A buzzer sounds the first time a message is shown on the multi-information display.
■If “Hybrid System Overheated Reduced Output Power” is shown
This message may be displayed when driving under severe operating conditions.
(For example, when drivin g up a long steep hill.)
Handling method: P. 5 2 7
■If “Maintenance Required for Hybrid Battery Cooling Parts at Your Dealer” is shown
The filter may be clogged, the air intake vent may be blocked or there may be a gap in
duct. Have maintenance performed on the hy brid battery (traction battery) cooling
component at your Lexus dealer.
■If “Hybrid Battery Low Shift Out of N to Recharge” is shown
Message is displayed when the remaining charge for the hybrid battery (traction battery)
is low.
As the hybrid battery (traction battery) can not be charged when the shift lever is in N,
when stopped for long periods of time shift the shift lever to P.
■If “Hybrid Battery Low Hybrid System St opped Shift to P and Restart” is shown
Message is displayed when the remaining charge for the hybrid battery (traction battery)
is low, because vehicle has been sh ifted N for a long period of time.
When operating the vehicle, restart the hybrid system.
■If “Shift to P Before Exiting Vehicle” is shown
Message is displayed when the driver’s door is opened without turning the power switch
to OFF with the shift lever in any position other than P.
Shift the shift lever to P.
■If “Shift Is in N Release Accele rator Before Shifting” is shown
Message is displayed when the accelerator pe dal has been depressed and the shift lever
is in N. Release the accelerator peda l and shift the shift lever to D or R.
■If “Maintenance Required Soon” is shown (U.S.A. only)
Indicates that all maintenance according to the driven distance on the maintenance
schedule
* should be performed soon.
Comes on approximately 4500 miles (7200 km) after the message has been reset.
If necessary, perform maintenance.
*: Refer to the separate “Scheduled Maintenance” or “Owner’s Manual Supplement” for
the maintenance interval applicable to your vehicle.

■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY USE ONLY” on the
tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire. ( P. 5 4 1 )
■When using the compact spare tire
As the compact spare tire is not equipped wi th a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare ti re will not be indicated by the tire pressure
warning system. Also, if you replace the compact spare tire after the tire pressure warn-
ing light comes on, th e light remains on.
■When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire compared to when
driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the follow-
ing steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.
