When trouble

If your vehicle overheats

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. 92) 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.

Correction procedures

7-2. Steps to take in an emergency

The coolant level is satisfactory if it is between the “F” and “L” lines on the res-
ervoir.

Reservoir
“F” line
“L” line
Radiator cap

Add coolant if necessary.

Water can be used in an emergency if

coolant is unavailable.

Start the engine and turn the air conditioning system on to check that the air
conditioning condenser 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 engine immediately and contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.

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.

●

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 seri-

ous injury.

●

Do not loosen the radiator cap or the coolant reservoir cap while the engine and radi-

ator are hot. High temperature steam or coolant could spray out.

NOTICE

■

When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. 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 foreign matter (such as sand or dust etc.).

●

Do not use any coolant additive.

558

7-2. Steps to take in an emergency

If the vehicle becomes stuck

Stop the engine. Set the parking brake and shift the shift lever to P.
Remove the mud, snow or sand from around the rear wheels.
Place wood, stones or some other material under the rear wheels to help pro-
vide traction.
Restart the engine.
Shift the shift lever to the D or R position and release the parking brake. Then,
while exercising caution, depress the accelerator pedal.

■

When it is difficult to free the vehicle

■

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 shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.

This may lead to unexpected rapid acceleration of the vehicle that may cause an acci-

dent and result in death or serious injury.

NOTICE

■

To avoid damaging the transmission and other components

●

Avoid spinning the rear wheels and depressing the accelerator pedal more than nec-

essary.

●

If the vehicle remains stuck even after these procedures are performed, the vehicle

may require towing to be freed.

●

When a warning message for the automatic transmission fluid temperature is dis-

played while attempting to free a stuck vehicle, immediately remove your foot from

the accelerator pedal and wait until the warning message disappears. Otherwise, the

transmission may become damaged. (

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.

Oil viscosity (0W-20 is explained here as an example):

• The 0W in 0W-20 indicates the characteristic of the oil which allows cold

startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.

• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the

oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.

How to read oil container label:
The International Lubricant Specification Advisory Committee (ILSAC) Cer-
tification Mark is added to some oil containers to help you select the oil you
should use.

Fuel information

■

Gasoline quality
In very few cases, driveability problems may be caused by the brand of gasoline you are

using. If driveability problems persist, try changing the brand of gasoline. If this does not

correct the problem, consult your Lexus dealer.

■

Recommendation of the use of gasoline containing detergent additives

●

Lexus recommends the use of gasoline that contains detergent additives to avoid the

build-up of engine deposits.

●

All gasoline sold in the U.S.A. contains minimum detergent additives to clean and/or

keep clean intake systems, per EPA’s lowest additives concentration program.

●

Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more informa-

tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official

website www.toptiergas.com.

■

Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated

gasolines, are available in some cities. These fuels are typically acceptable for use, pro-

viding they meet other fuel requirements.
Lexus recommends these fuels, since the formulations allow for reduced vehicle emis-

sions.

You must only use unleaded gasoline.
Select premium unleaded gasoline with an octane rating of 91 (Research
Octane Number 96) or higher required for optimum engine performance
and fuel economy. If the octane rating is less than 91, damage to the engine
may occur and may void the vehicle warranty.
At minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. .
