When trouble arises
NOTICE
When performing an emergency repair
Perform the emergency repair without removing the nail or screw that has
punctured the tread of the tire. If the object that has punctured the tire is
removed, repair by the emergency tire puncture repair kit may not be possible.
The kit is not waterproof. Make sure that the kit is not exposed to water, such
as when it is being used in the rain.
Do not put the kit directly onto dusty ground such as sand at the side of the
road. If the kit vacuums up dust etc., a malfunction may occur.
Use the kit with the top facing upward. The kit cannot work properly if it is
laid on its side.
Handling the emergency tire puncture repair kit
The compressor power source should be 12 V DC suitable for vehicle use. Do
not connect the compressor to any other source.
If gasoline splatters on the kit, the kit may deteriorate. Take care not to allow
gasoline to contact it.
Store the kit in its assigned place out of reach of children.
Do not disassemble or modify the kit. Do not subject parts such as the air
pressure indicator to impacts. This may cause a malfunction.
To avoid damage to the tire pressure warning valves and transmitters (vehicles
with the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional or other qualified service shop as soon as possible. Make sure to
replace the tire pressure warning valve and transmitter when replacing the tire.

When trouble arises
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 sys-
tem, and then stop the hybrid system.

6609-2. Customization
CT200h_OM_OM76102E_(EE)
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 position other than P, all the doors
will be locked.
• If the vehicle is started with all the doors locked, the speed linked door lock-
ing function would not operate.
• If the vehicle is started with any door unlocked, the speed linked door lock-
ing function will operate.
When the smart entry & start system is off, smart door unlocking cannot be cus-
tomized.
When the doors remain closed after unlocking the doors and the automatic door
lock function is activated, the signals will be generated in accordance with the
Operation signal (buzzer) and the Operation signal (emergency flashers) set-
tings.
In the following situations, customize mode in which the settings can be changed
through the multi-information display will automatically be turned off.
A warning message appears after the customize mode screen is displayed.
The power switch is turned off.
The vehicle begins to move while the customize mode screen is displayed.
WA R N I N G
Cautions during customization
As the hybrid system needs to be operating during customization, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may col-
lect 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.
