Before driving
CT200h_EE (OM76041E)
Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every few
months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Charging the 12-volt battery
P. 6 2 3
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

CT200h_EE (OM76041E)
Alarms and warning messages
A combination of exterior and interior alarms as well as warning messages
shown on the multi-information display is used to prevent theft of the vehi-
cle and accidents resulting from erroneous operation. Take appropriate mea-
sures in response to any warning message on the multi-information display.
(P. 565)
The following table describes circumstances and correction procedures
when only alarms are sounded.
Security feature
P. 8 1
Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.

2-1. Driving procedures
CT200h_EE (OM76041E)
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 6 4 1 )
For efficient use
Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift position in the N position for an extended period of
time may discharge the hybrid battery (traction battery). The vehicle
cannot run if the hybrid battery (traction battery) is discharged.
CAUTION
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid
system operating. This prevents the vehicle from creeping.

2-1. Driving procedures
CT200h_EE (OM76041E)
About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
Automatically P position selection function
When the “POWER” switch is in ON mode while the shift position is in a
position other than P and the vehicle is stopped completely, pressing the
“POWER” switch will cause the automatically P position selection function
to operate together with the “POWER” switch being turned to off.
If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-
volt battery in this situation. (P. 620)
Sport mode automatic deactivation
Sport mode is automatically deactivated if the “POWER” switch is turned
off after driving in sport mode.
After recharging/reconnecting the 12-volt battery
P. 4 9 9
Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features P. 655)

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your hybrid transmis-
sion. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional before towing.
The hybrid system is operating but the vehicle will not move.
The vehicle makes an abnormal sound.
If there is a malfunction in the P position control system, the smart
entry & start system or the immobilizer system, or if the 12-volt
battery is discharged, the vehicle cannot be towed with the front
wheels on the ground, as the front wheels may be locked. In this
case, transport the vehicle with both front wheels or all four wheels
lifted.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional or a commercial towing service, using a lift-
type truck or flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
