6) Set the AT select lever to each gear position
while checking that the demanded gear position is
correctly attained.
39.HEATER & VENTILATION
Operate the heater and ventilation system to check
for normal airflow outlet control, air inlet control, air-
flow capacity, and heating performance.
40.AIR CONDITIONER
Operate the air conditioner. Check that the A/C
compressor operates normally and enough cooling
is provided.
41.ATF LEVEL
Check that the ATF level is normal. If insufficient,
check that no leaks are found. Then add the neces-
sary amount of the specified ATF.
42.POWER STEERING FLUID LEVEL
Check that the power steering fluid level is normal.
If insufficient, check that no leaks are found. Then
add the necessary amount of the specified power
steering fluid.
43.FLUID LEAK CHECK
Check the entire areas of the vehicle for any trace
of coolant/oil/fluid leaks.
44.WATER LEAK TEST
Spray the vehicle with water and check that no wa-
ter enters the passenger compartment.
 Before performing the water leakage test, re-
move anything that may obstruct the operation or
which must be kept dry.
 Close all windows completely, and then close all
doors tightly. Close the hood before starting the
test.
 Connect a hose to a tap, and spray water on the
vehicle. The rate of water discharge must be ap-
prox. 20 — 252 (5.3 — 6.6 US gal, 4.4 — 5.5 Imp
gal) per minute.
When spraying water on areas adjacent to the floor
and wheel house, increase the pressure. When di-
recting water on areas other than the floor portion
and wheel house, decrease the pressure. But the
force of water must be made strong occasionally by
pressing the end of the hose.
NOTE:
Be sure to keep the hose at least 10 cm (3.9 in)
from the vehicle.
Check the following areas:
 Front window and body framework mating por-
tion
 Door mating portions
 Glass mating portions
 Rear quarter window mating portions
