to R
*.
 When the shift lever is shifted 
from P or R to forward drive 
shift position such as D
*.

NOTICE
■When parking the vehicle
Always set the parking brake and 
shift the shift lever to P. Failure to 
do so may cause the vehicle to 
move or the vehi cle may acceler-
ate suddenly if the accelerator 
pedal is accidentally depressed.
■Avoiding damage to vehicle 
parts
●Do not turn the steering wheel 
fully in either direction and hold 
it there for an extended period 
of time.
Doing so may damage the 
power steering motor.
●When driving over bumps in the 
road, drive as slowly as possible 
to avoid damagi ng the wheels, 
underside of the vehicle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause 
the following situations. Hold the 
steering wheel firmly and gradu-
ally depress the brake pedal to 
slow down the vehicle.
●It may be difficult to control your 
vehicle.
●The vehicle will make abnormal 
sounds or vibrations.
●The vehicle will lean abnor-
mally.

■When encountering flooded 
roads
Do not drive on a road that has 
flooded after heavy rain etc. 
Doing so may cause the following 
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by 
water immersion
In the event that you drive on a 
flooded road and the vehicle 
becomes flooded or stuck in mud 
or sand, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in the quantity and 
quality of the engine oil, tran-
saxle fluid, etc.
●Lubricant condition for the bear-
ings and suspension joints 
(where possible), and the func-

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.

Maintenance and care
■Adding fluid
1 Slide and lift up the rubber 
strip to partly remove it as 
shown.
2 Disconnect the claws and 
remove the service cover.
3 Remove the reservoir cap.
4 Add brake fluid slowly while 
checking the fluid level.
Make sure to check the fluid 
type and prepare the necessary 
item.

J1703 brake fluid
Item
Clean funnel
■Brake fluid can absorb moisture 
from the air
Excess moisture in the brake fluid 
can cause a dangerous loss of brak-
ing efficiency. Use only newly 
opened brake fluid.
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that 
there are no loose connections, 
cracks, or loose clamps.
WARNING
■When filling the reservoir
Take care as brake fluid can harm 
your hands and eyes and damage 
painted surfaces.
If fluid gets on your hands or in 
your eyes, flush the affected area 
with clean water immediately.
If you still experi ence discomfort, 
see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level 
to go down slight ly as the brake 
pads wear out or when the fluid 
level in the accumulator is high.
If the reservoir needs frequent 
refilling, there m ay be a serious 
problem.
