5-1. Essential information
CT200h_EE (OM76041E)
Emergency towing
If a tow truck is not available in
an emergency, your vehicle
may be temporarily towed
using a cable or chain secured
to the emergency towing eye-
let(s). This should only be
attempted on hard surfaced
roads for short distances at
under 30 km/h (18 mph).
A driver must be in the vehicle
to steer and operate the brakes.
The vehicle’s wheels, drive
train, axles, steering and brakes
must be in good condition.

5-1. Essential information
CT200h_EE (OM76041E)
CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
Do not turn the “POWER” switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
NOTICE
To prevent damaging the vehicle
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the vehi-
cle could be damaged while being towed.
To prevent causing serious damage to the hybrid transmission when towing
using a wheel-lift type truck
Never tow this vehicle from the front with the rear wheels on the ground.
To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
To prevent causing serious damage to the hybrid transmission in emergency
towing
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the hybrid transmission.

When trouble arises
CT200h_EE (OM76041E)
*1:Open door warning buzzer:
P. 569
*2:Driver’s and front passenger’s seat belt buzzer:
The driver’s and front passenger’s seat belt buzzer sounds to alert the
driver and front passenger that his or her seat belt is not fastened. The
buzzer sounds for 30 seconds after the vehicle reaches a speed of 20 km/
h (12 mph). Then, if the seat belt is still unfastened, the buzzer will
sound in a different tone for 90 more seconds.
Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and the warning
buzzer to sound even if a passenger is not sitting in the seat.
If a cushion is placed on the seat, the sensor may not detect a passenger,
and the warning light may not operate properly.
Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient of the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.

If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
Customization that can be configured at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 655)
However, Lexus recommends that the seat belt reminder buzzer be opera-
tional to alert the driver and front passenger when seat belts are not fastened.
CAUTION
If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.

CAUTION
When fixing the flat tire
Stop your vehicle in a safe and flat area.
Connect the valve and hose securely with the tire installed on the vehicle.
If the hose is not properly connected to the valve, air leakage may occur or
sealant may be sprayed out.
If the hose comes off the valve while inflating the tire, there is a risk that
the hose will move abruptly due to air pressure.
After inflation of the tire has completed, the sealant may splatter when the
hose is disconnected or some air is let out of the tire.
Keep back from the tire while it is being repaired, as there is a chance of it
bursting while the repair operation is being performed. If you notice any
cracks or deformation of the tire, turn off the compressor switch and stop
the repair operation immediately.
The kit may overheat if operated for a long period of time. Do not operate
the compressor continuously for more than 10 minutes.
Parts of the kit become hot during operation. Be careful handling the kit
during and after operation.
Do not attach the vehicle speed warning sticker to an area other than the
one indicated. If the sticker is attached to an area where an SRS airbag is
located, such as the pad of the steering wheel, it may prevent the SRS air
bag from operating properly.
Driving to spread the liquid sealant evenly
Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
If the vehicle does not drive straight or you feel a pull through the steering
wheel, stop the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/
cm
2 or bar, 19 psi) or below, this may indicate severe tire damage.
