the image that is actually displaye d on the multi-information display.
■Warning message in radar cruise mode (if equipped)
In the following situations, 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
■Resetting the message indicating maintenance is required (U.S.A. only)
Make sure to reset the oil change system. ( →P. 4 6 6 )

When trouble arises
■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. 577)
■After completing the tire change
The tire pressure warning system must be reset. ( →P. 4 8 9 )
■When using the compact spare tire
As the compact spare tire is not equipped with a tire pressure warning valve and trans-
mitter, low inflation pressure of the spare tire 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, the 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.

■When using the compact spare tire
●Remember that the spare tire provided is specifically designed for use with your vehi-
cle. Do not use your spare tire on another vehicle.
●Do not use more than one spare tire simultaneously.
●Replace the spare tire with a standard tire as soon as possible.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations
that cause sudden engine braking.
■When the compact spare tire is attached
The vehicle speed may not be correctly detected, and the following systems may not
operate correctly:

If your vehicle overheats
■If the high coolant temperature warning light comes on or flashes
Stop the vehicle in a safe place and turn off the air conditioning system, and
then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Lexus
dealer.
The following may indicate that your vehicle is overheating.
●The high coolant temper ature warning light (→P. 528) comes on or flashes,
or a loss of hybrid system power is experienced. (For example, the vehicle
speed does not increase.)
●The warning message indicating overheats is shown on the multi-informa-
tion display. ( →P. 5 4 0 )
●Steam comes out from under the hood.

CT200h_OM_OM76174U_(U)9-1. Spec
ifications
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and they rep-
resent the tire’s ability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to th is tire is based on braking (straight
ahead) traction tests and does not include cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and
not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.

■Vehicle customization
●When the Speed linked door locking function and the Shift position linked door locking
function are both on, the door lock operates as follows.
• When shifting the shift position to any po sition other than P, all the doors will be
locked.
• If the vehicle is started with all the doors locked, the Speed linked door locking func- tion would not operate.
• If the vehicle is started with any door un locked, the Speed linked door locking func-
tion will operate.
●When the smart access system with push-butto n start is off, Smart door unlocking can-
not be customized.
●When the doors remain closed after unlock ing the doors and the automatic door lock
function is activated, the signals will be generated in accordance with the operation sig-
nal (buzzer) and the operation signal (emergency flashers) settings.
■In the following situations, customize mode in which the settings can be changed
through the “DISP” switch will automatically be turned off.
●A warning message appears after the cu stomize mode screen is displayed.
●The power switch is turned off.
●The vehicle begins to move while the customize mode screen is displayed.

■Cautions during customization
As the hybrid system needs to be operating during customization, ensure that the vehi-
cle is parked in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful carbon monoxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is operating while
customizing features.
