7
When trouble arises
1Stop the vehicle in a safe place and 
turn off the air conditioning system, 
and then stop the engine.
2 If you see steam: 
Carefully lift the hood after the 
steam subsides.
If you do not see steam: 
Carefully lift the hood.
3 After the engine has cooled down 
sufficiently, inspect the hoses and 
WARNING
●When working with the 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 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 battery support, terminals, and 
other battery-related parts.
●Do not allow children near the battery.
■When replacing the battery
When the vent plug and indicator are 
close to the hold down clamp, the battery 
fluid (sulfuric acid) may leak.
NOTICE
■When handling jumper cables
When connecting the jumper cables, 
ensure that they do not become entan-
gled in the cooling fan or engine drive 
belt.
If your vehicle overheats
The following may indicate that 
your vehicle is overheating.
 The engine coolant temperature 
gauge ( P.64, 67) is in the red 
zone or a loss of engine power is 
experienced. (For example, the 
vehicle speed does not increase.)
 “Engine Coolant Temp High Stop 
in a Safe Place See Owner’s 
Manual” is shown on the multi-
information display.
 Steam comes out from under the 
hood.

radiator core (radiator) for any 
leaks.
Radiator
Cooling fan
If a large amount of coolant leaks, immedi-
ately contact your Lexus dealer.
4The coolant level is satisfactory if it 
is between the “F” and “L” lines on 
the reservoir.
Reservoir
“F” line
“L” line
Coolant inlet cap
5 Add coolant if necessary.
Water can be used in an emergency if  coolant is unavailable.
6
Start the engine and turn the air 
conditioning system on to check 
that the radiator cooling fan oper-
ates 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 con-
ditioning system on  and off repeatedly. 
(The fan may not oper ate in freezing tem-
peratures.)
7 If the fan is not operating:
Stop the engine immediately and 
contact your Lexus dealer.
If the fan is 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 com-
partment may be very hot.

When trouble arises
1Stop the engine. Set the parking 
brake and shift the shift lever to P.
2 Remove the mud, snow or sand 
from around the front wheels.
3 Place wood, stones or some other 
material under the front wheels to 
help provide traction.
4 Restart the engine.
5 Shift the shift lever to D or R and 
release the parking brake. Then, 
while exercising caution, depress 
the accelerator pedal.
■When it is difficult to free the vehicle
Press the   switch  to turn off TRAC.
WARNING
●Keep hands and clothing (especially a 
tie, a scarf or a muffler) away from the 
fan and belts. Failure to do so may 
cause the hands or clothing to be 
caught, resulting in serious injury.
●While the engine and radiator are hot, 
do not loosen or remove the coolant 
inlet cap or coolant reservoir cap. 
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 sys-
tem
Observe the following precautions:
●Avoid contaminating the coolant with 
foreign matter (such as sand or dust 
etc.).
●Do not use any coolant additive.
If the vehicle becomes stuck
Carry out the following proce-
dures if the tires spin or the vehicle 
becomes stuck in mud, dirt or snow:

Vehicle specifications
■Traction AA, A, B, C
The traction grades, from highest to 
lowest, are AA, A, B and C, and they 
represent the tire’s  ability to stop on 
wet pavement as measured under con-
trolled conditions on  specified govern-
ment test surfaces of asphalt and 
concrete.
A tire marked C may have poor traction 
performance.
Warning: The traction grade assigned to 
this tire is based on braking (straight 
ahead) traction tests and does not include 
cornering (turning) traction.
■Temperature A, B, C
The temperature grades are A (the 
highest), B, and C, representing the 
tire’s resistance to the generation of 
heat and its ability to dissipate heat  when tested under controlled condi-
tions on a specified indoor laboratory 
test wheel.
Sustained high temperature can cause the 
material of the tire to degenerate and 
reduce tire life, and excessive temperature 
can lead to sudd
en tire failure.
Grade C corresponds to  a level of perfor-
mance which all passenger car tires must 
meet under the Fede ral Motor Vehicle 
Safety Standard No. 109.
Grades B and A represent higher levels of 
performance on the laboratory test wheel 
than the minimum required by law.
Warning: The temperature grades of a tire 
assume that it is properly inflated and not 
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and 
possible tire failure.
