CAUTION
■When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of death
or serious injury:
●When using a floor jack, follow the instructions of the manual provided with the
jack.
●Do not use the jack that was supplied with your vehicle.
●Do not put any part of your body underneath the vehicle when it is supported
only by the floor jack.
●Always use floor jack and/or automotive jack stands on a solid, flat, level surface.
●Do not start the hybrid system while the vehicle is supported by the floor jack.
●Stop the vehicle on level, firm ground, firmly set the parking brake and shift the
shift lever to P.
●Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage the vehi-
cle and may cause the vehicle to fall off the floor jack.
●Do not raise the vehicle while someone is in the vehicle.
●When raising the vehicle, do not place any object on top of or underneath the
floor jack.
●Be sure to turn off the height control an d stop the hybrid system. Otherwise, the
vehicle height may change in the automatic leveling function. ( P. 2 8 7 )
●Lift up the vehicle using a floor jack such as
the one shown in the illustration.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light ) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire trea d life, and may affect the vehicle's handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driv er's responsibility to maintain correct tire
pressure, even if under-inflation has not re ached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indicate when th e system is not operating properly. The
TPMS (tire pressure warning system) malfunction indicator is combined with the
low tire pressure telltale (tire pressure warning light). When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists . When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure as intended.

CAUTION
■Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
●Put the jack properly in its jack point.
●Do not put any part of your body under the vehicle while it is supported by the
jack.
●Do not start the hybrid system or drive the vehicle while the vehicle is supported
by the jack.
●Do not raise the vehicle while someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●Be sure to turn off the height control and stop the hybrid system.
●When lowering the vehicle, make sure that there is no-one near the vehicle. If
there are people nearby, warn them vocally before lowering.

LS600hL_U(OM50E41U)
Ensure that the shift lever is in P and depress the brake pedal.
Touch the Lexus emblem side of
the electronic key to the power
switch.

keeping the brake pedal depressed.
In the event that the hybrid system still cannot be started, contact your
Lexus dealer.
■Stopping the hybrid system
Shift the shift lever to P and press the power switch as you normally do when stop-
ping the hybrid system.
■Replacing the key battery
As the above procedure is a temporary meas ure, it is recommended that the elec-
tronic key battery be replaced immediately when the battery is depleted. ( P. 4 7 2 )
■Changing power switch modes
Within 10 seconds of the buzzer soundi ng, release the brake pedal and press the
power switch.

5327-2. Steps to take in an emergency
LS600hL_U(OM50E41U)
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.)
If the fan is not operating:
Stop the hybrid system immediately and contact your Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the nearest Lexus dealer.
■If “Hybrid System Overheat” is shown on the multi-information dis-
play
Stop the vehicle in a safe place.
Stop the hybrid system and carefully lift the hood.
After the hybrid system has
cooled down, inspect the
hoses and radiator core (radia-
tor) for any leaks.Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact your
Lexus dealer.

CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●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.
●After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automatically
start, or the cooling fan may suddenly oper ate even if the gasoline engine stops.
Do not touch or approach rotating parts such as the fan, which may lead to fin-
gers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in
serious injury.
NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid syst em has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too quickly can cause da mage 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 any coolant additive.
●Do not loosen the coolant reservoir caps
while the hybrid system and radiator are
hot.
High temperature steam or coolant could
spray out.
