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. 572) comes
on or flashes, or a loss of hybrid system power is experienced.
(For example, the vehicle speed does not increase.)
“HYBRID SYSTEM OVERHEAT” (P. 586) is shown on

if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”

Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system
on to check that the radiator cooling fan operates and to
check for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on
immediately after a cold start. Confirm that the fan is operating
by checking the fan sound and air flow. If it is difficult to check
these, turn the air conditioning system on and off repeatedly.
(The fan may not operate in freezing temperatures.)

CAUTION
To prevent an accident or injury when inspecting under the hood of your
vehicle
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injuries such as burns.
Check that the indicator on the “POWER” switch and the “READY” indi-
cator are off.
On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fan may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fan, which may lead to
fingers or clothing (especially a tie, a scarf or a muffler) getting caught,
resulting in serious injury.
Do not loosen the coolant reservoir cap while the hybrid system and radi-
ator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use commercially available coolant additives.

If the vehicle becomes stuck
CAUTION
When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the sur-
rounding area is clear to avoid striking other vehicles, objects or people. The
vehicle may also lunge forward or lunge back suddenly as it becomes free.
Use extreme caution.
When changing the shift position
Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any positions other than P or N may cause the
vehicle to accelerate abruptly, causing an accident and resulting in death or
serious injury.
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Set the parking brake and shift the shift position to P.
Stop the hybrid system.
Remove the mud, snow or sand from around the stuck
tire.
Place wood, stones or some other material under the tires
to help provide traction.
Restart the hybrid system.
Shift the shift position to D or R, release the parkingSTEP1

If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following proce-
dure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase
the effort required to slow the vehicle.
Shift the shift position to N.
If the shift position is shifted to N
After slowing down, stop the vehicle in a safe place by
the road.
Stop the hybrid system.
If the shift position cannot be shifted to N
Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
To stop the hybrid system,
press and hold the “POWER”
switch for 2 consecutive sec-
onds or more, or press it
briefly 3 times or more in
succession.

CAUTION
If the hybrid system has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake
pedal harder to depress and the steering wheel heavier to turn. Decelerate as
much as possible before turning off the hybrid system.
