Maintenance and care
●When the engine is new, for 
example directly after purchasing 
the vehicle or after replacing the 
engine
●If low quality oil or oil of an inap-
propriate viscosity is used
●When driving at high engine 
speeds or with a heavy load, or 
when driving while accelerating or 
decelerating frequently
●When leaving the engine idling for 
a long time, or when driving fre-
quently through heavy traffic
The coolant level is satisfactory 
if it is between the “MAX” and 
“MIN” lines on the reservoir 
when the engine is cold.
Reservoir
“MAX” line
“MIN” line
If the level is on or below the “MIN” 
line, add coolant  up to the “MAX” 
line. ( P.362)
■Coolant selection
Only use “Toyota Super Long Life 
Coolant” or a similar high quality 
ethylene glycol ba sed non-silicate, 
non-amine, non-nitrite, and 
non-borate coolant with long-life 
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is 
a mixture of 50% c oolant and 50% 
deionized water. (Minimum tem-
WARNING
■Used engine oil
●Used engine oil  contains poten-
tially harmful contaminants 
which may cause skin disorders 
such as inflammation and skin 
cancer, so care should be taken 
to avoid prolonged and 
repeated contact. To remove 
used engine oil from your skin, 
wash thoroughly with soap and 
water.
●Dispose of used oil and filters 
only in a safe an d acceptable 
manner. Do not dispose of used 
oil and filters in household trash, 
in sewers or onto the ground.
Call your Toyota dealer, service 
station or auto parts store for 
information concerning recy-
cling or disposal.
●Do not leave used engine oil 
within the rea ch of children.
NOTICE
■To prevent serious engine 
damage
Check the oil level on a regular 
basis.
■When replacing the engine oil
●Be careful not to spill engine oil 
on the vehicle components.
●Avoid overfilling, or the engine 
could be damaged.
●Check the oil level on the dip-
stick every time  you refill the 
vehicle.
●Be sure the engine oil filler cap 
is properly tightened.

perature: -31°F [-35°C])
Canada:
“Toyota Super Long Life Coolant” is 
a mixture of 55% coolant and 45% 
deionized water. (Minimum tem-
perature: -44°F [-42°C])
For more details about coolant, con-
tact your Toyota dealer.
■If the coolant level drops within 
a short time of replenishing
Visually check the radiator, hoses, 
engine coolant reservoir caps, drain 
cock and water pump.
If you cannot find  a leak, have your 
Toyota dealer test the cap and 
check for leaks in the cooling sys-
tem.
Check the radiator and con- denser and clear away any for-
eign objects. If either of the 
above parts is extremely dirty or 
you are not sure of their condi-
tion, have your vehicle 
inspected by your Toyota dealer.
■Checking fluid level
The brake fluid level should be 
between the “MAX” and “MIN” 
lines on the tank.
WARNING
■When the engine is hot
Do not remove the engine coolant 
reservoir cap. ( P.363)
The cooling system may be under 
pressure and may spray hot cool-
ant if the cap is removed, causing 
serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor 
straight antifreeze. The correct 
mixture of water and antifreeze 
must be used to provide proper 
lubrication, corrosion protection 
and cooling. Be sure to read the 
antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to 
prevent it from d amaging parts or 
paint.
Checking the radiator and 
condenser
WARNING
■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and 
cause serious injuries, such as 
burns.

Manual is displayed
●If “Engine Coolant Temp High” is 
displayed, follow the instructions 
accordingly. ( P.362)
●If any of the following messages 
are displayed on the multi-infor-

●If any of the following messages 
are displayed on the multi-infor-
mation display, it may indicate a 
malfunction. Immediately stop the 
vehicle and contact your Toyota 
dealer.
• “Braking  Power Low”
• “Charging System Malfunction”
• “Oil Pressure Low”
 Stop the vehicle in a safe 
place on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
NOTICE
■If “High Power Consumption 
Partial Limit  on AC/Heater 
Operation” is displayed fre-
quently
There is a possible malfunction 
relating to the charging system or 
the battery may be  deteriorating. 
Have the vehicle inspected by 
your Toyota dealer.
If  you have a flat tire 
(vehicles without 
spare tire)
Your vehicle is not equipped 
with a spare tire, but instead 
is equipped with an emer-
gency tire puncture repair 
kit.
A puncture caused by a nail 
or screw passing through 
the tire tread can be 
repaired temporarily using 
the emergency tire puncture 
repair kit. (The kit contains a 
bottle of sealant. The seal-
ant can be used only once 
to temporarily repair one 
tire without removing the 
nail or screw from the tire.) 
After temporarily repairing 
the tire with the kit, have the 
tire repaired or replaced by 
your Toyota dealer.
WARNING
■If you have a flat tire
Do not continue driving with a flat 
tire.
Driving even a short distance with 
a flat tire can damage the tire and 
the wheel beyond repair, which 
could result in an accident.
Before repairing the tire

1Stop the vehicle in a safe 
place and turn off the air con-
ditioning 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 radiator core (radi-
ator) for any leaks.

If a large amount of coolant leaks, 
immediately contact your Toyota 
dealer.

The coolant level is satisfac-
tory if it is between the “MAX” 
and “MIN” lines on the reser-
voir.

The following may indicate 
that your vehicle is over-
heating.
The engine coolant tem-
perature gauge ( P.72, 75) 
is in the red zone or a loss 
of engine power is experi-
enced. (For example, the 
vehicle speed does not 
increase.)

able.
6Start the engine and turn the 
air conditioning system on to 
check that the radiator cool-
ing fan operates and to check 
for coolant leaks from the 
radiator or hoses.
The fan operates when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm 
that the fan is op erating by check-
ing 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 oper-
ate in freezing temperatures.)
7 If the fan is not operating:
Stop the engine immediately 
and contact your Toyota 
dealer.
If the fan is operating:
Have the vehicle inspected at 
the nearest Toyota dealer.
WARNING
■When inspecting under the 
hood of your vehicle
Observe the following precau-
tions. 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 sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf 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.
●Do not loosen the coolant reser-
voir caps while the engine and 
radiator are hot.
High temperature steam or 
coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the 
engine has cooled down suffi-
ciently. 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 precau-
tions:
●Avoid contaminating the coolant 
with foreign matter (such as 
sand or dust etc.).
●Do not use any coolant additive.
