LX570_OM_OM60L21U_(U) ■
Starting the engine when the battery is discharged
The engine cannot be started by push-starting. ■
Avoiding a discharged battery ●
Turn off the headlights and the audio system while the engine is off. ●
Turn off any unnecessary electrical compon ents when the vehicle is running at a
low speed for an extended period, such as in heavy traffic, etc.■
Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical
appliances. If the vehicle is left for a long time, the battery may discharge, and the
engine may be unable to start. (The battery recharges automatically during driving.) ■
When the battery is removed or discharged ●
The power back door must be initialized. ( P. 6 0 )●
Make sure the key is not inside the vehicle when recharging or replacing the
battery. The key may be locked in the vehicle if the alarm is activated. ( P. 1 2 0 )Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Open and close any of the do ors with the “ENGINE START
STOP” switch off.
Maintain the engine speed of th e second vehicle and turn the
“ENGINE START STOP” switch to IGNITION ON mode,
then start the vehicle’s engine.
Once the vehicle’s engine ha s started, remove the jumper
cables in the exact reverse ord er in which they were con-

Correction procedures
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine 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 your Lexus
dealer.The following may indicate that your vehicle is overheating.
● The needle of the engine coolant temperature gauge ( P. 1 9 0 )
enters the red zone or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam is coming from under the hood. STEP 1

is between the “F” and “L” lines on
the reservoir.
Reservoir
“F”

Radiator cap
Add coolant if necessary.
( P. 74 8 ) Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans op erate and to check for coolant
leaks from the radiator or hoses. The fans operate when the air conditio ning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking
the fan sound and air flow. If it is diff icult to check these, turn the air con-
ditioning system on and off repeatedly. (The fans may not operate in
freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Lexus dealer.

LX570_OM_OM60L21U_(U) CAUTION■
To prevent an accident or injury when in specting 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 compartm ent may be very hot, causing serious
injury such as burns. ●
Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fans
and belts. Failure to do so may cause the hands or clothing to be caught, resulting
in serious injury. ●
Do not loosen the radiator cap or the c oolant reservoir cap while the engine and
radiator are hot.
Serious injury, such as burns, may resu lt from hot coolant and steam released
under pressure.
NOTICE■
When adding engine coolant
Wait until the engine has cooled do wn before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too quickly
can cause damage to the engine. ■
To prevent damage to the cooling system
Observe the following precautions: ●
Avoid contaminating the coolant with foreig n matter (such as sand or dust etc.).●
Do not use any coolant additives.
