WARNING

12-volt battery precautions

The 12-volt battery contains poisonous and corrosive acidic electrolyte, while related

parts contain lead and lead compounds. Observe the following precautions when han-

dling the 12-volt battery:

●

When working with the 12-volt battery, always wear safety glasses and take care not

to allow any battery fluids (acid) to come into contact with skin, clothing or the vehicle

body.

●

Do not lean over the 12-volt battery.

●

In the event that battery fluid comes into contact with the skin or eyes, immediately

wash the affected area with water and seek medical attention.

Place a wet sponge or cloth over the affected area until medical attention can be

received.

●

Always wash your hands after handling the 12-volt battery support, terminals, and

other battery-related parts.

●

Do not allow children near the 12-volt battery.

■

After recharging the 12-volt battery

Have the 12-volt battery inspected at any authorized Lexus retailer or Lexus autho-

rized repairer, or any reliable repairer as soon as possible.

If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery to

emit a malodorous gas, which may be detrimental to the health of passengers.

■

When replacing the 12-volt battery



P. 609

NOTICE

■

When handling jumper cables

When connecting the jumper cables, ensure that they do not become entangled in the

cooling fans or belt.

■

To prevent damaging the vehicle

The exclusive jump starting terminal is to be used when charging the 12-volt battery

from another vehicle in an emergency. It cannot be used to jump start another vehicle.

8-2. Steps to take in an emergency

If your vehicle overheats

●

The high coolant temperature warning light (



P. 667) comes on or flashes,

or a loss of hybrid system power is experienced. (For example, the vehicle
speed does not increase.)

●

The warning message indicating overheats is shown on the multi-information
display. (



P. 682)

●

Steam comes out from under the hood.

■

If the high coolant temperature warning light comes on or flashes

Stop the vehicle in a safe place and turn off the air conditioning system, and
then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system 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 any autho-

rized Lexus retailer or Lexus

authorized repairer, or any reli-

able repairer.

The following may indicate that your vehicle is overheating.

The coolant level is satisfactory if it is between the “FULL” and “LOW” lines
on the reservoir.

Reservoir
“FULL” line
“LOW” line

Add coolant if necessary.

Water can be used in an emergency

if coolant is unavailable.

Start the hybrid system and turn the air conditioning system on to check
that the radiator cooling fans operate and to check for coolant leaks from
the radiator or hoses.

The fans operate when the air conditioning system is turned on immediately after a

cold start. Confirm that the fans are 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 fans may not operate in freezing temperatures.)

If the fans are not operating:
Stop the hybrid system immediately and contact any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.
If the fans are operating:
Have the vehicle inspected at the nearest any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.

WARNING

■

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 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 radiator are hot.

High temperature steam or coolant could spray out.

NOTICE

■

When adding engine/power control unit coolant

Add coolant slowly after the hybrid system has cooled down sufficiently. Adding cool

coolant to a hot hybrid system 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 any coolant additive.

8-2. Steps to take in an emergency

If the vehicle becomes stuck

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 parking brake and carefully apply
the accelerator to free the vehicle.

■

When it is difficult to free the vehicle

Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt or snow:

Press

to turn off TRC. (



P. 370)

WARNING

■

When attempting to free a stuck vehicle

If you choose to push the vehicle back and forth to free it, make sure the surrounding

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.

Engine oil selection

“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom-
mends the use of approved “Toyota Genuine Motor Oil”. Another motor oil of
matching quality can also be used.
Oil grade:
0W-20 and 5W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving” or SN PLUS “Resource- Conserving”; or ILSAC
multigrade engine oil

Recommended viscosity (SAE):
SAE 0W-20 is filled into your Lexus
vehicle at manufacturing, and the
best choice for good fuel economy
and good starting in cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used. How-
ever, it should be replaced with SAE
0W-20 at the next oil change.
