CT200h_OM_OM76102E_(EE)
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Open and close any of the doors of your vehicle with the power switch
off.
Maintain the engine speed of the second vehicle and start the hybrid
system of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator light
does not come on, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Once the hybrid system has started, remove the jumper cables in the
exact reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the fuse
box cover to its original position.
Once the hybrid system starts, have the vehicle inspected at any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional as soon as possible.
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system is off.
Turn off any unnecessary electrical components when the vehicle is running at
a low speed for an extended period, such as in heavy traffic.
When the 12-volt battery is removed or discharged
The hybrid system may not start. (P. 507)
If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels will
be locked. (P. 562)
When the 12-volt battery is reconnected, start the hybrid system and confirm
that the shift position can be changed to each position using the shift position
indicator.
Make sure that the key is not inside the vehicle when recharging or replacing
the 12-volt battery. The key may be locked in the vehicle if the alarm is acti-
vated. (P. 9 3 )

When trouble arises
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the 12-volt battery
may discharge, and the hybrid system may be unable to start. (The 12-volt bat-
tery recharges automatically while the hybrid system is operating.)
WA R N I N G
Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12-volt battery:
Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
Do not allow the other end of the jumper cable connected to the “+” terminal
to come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
Do not smoke, use matches, cigarette lighters or allow open flame near the
12-volt battery.
12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precau-
tions when handling the 12-volt battery:
When working with the 12-volt battery, always wear safety glasses and take
care not to allow any battery fluids (acid) to come into contact with skin,
clothing or the vehicle body.
Do not lean over the 12-volt battery.
In the event that battery fluid comes into contact with the skin or eyes, imme-
diately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can
be received.
Always wash your hands after handling the 12-volt battery support, terminals,
and other battery-related parts.
Do not allow children near the 12-volt battery.
After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional as soon as possible.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt bat-
tery to emit a malodorous gas, which may be detrimental to the health of pas-
sengers.

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.
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 any
authorized Lexus dealer or
repairer, or another duly quali-
fied and equipped professional.
The following may indicate that your vehicle is overheating.
The high coolant temperature warning light (P. 570) comes on or
flashes, or a loss of hybrid system power is experienced. (For exam-
ple, the vehicle speed does not increase.)
The warning message indicating overheats is shown on the multi-
information display. (P. 583)
Steam comes out from under the hood.
