1. APPEARANCE CHECK
1) If the vehicle is covered with protective coating,
visually check the vehicle body for damage and
dents.
2) If there is no protective coating, check the body
paints for small areas of damage or stains and re-
pair as necessary.
3) Check the window glass, door glass, and lights
for any cracks or damage and repair or replace the
parts as necessary.
4) Check the plated parts, such as the grilles and
door knobs, for damage or loss of gloss and repair
or replace the parts as necessary.
2. TIRE CHECK
 Check the tire outer faces for any damage.
 Check the tire air pressure by referring to the fol-
lowing table.
3. FUSE INSTALLATION
A vehicle just delivered has no fuse for the room
lamp circuit to prevent battery discharge. Attach a
15 A fuse (A) as shown in the figure.
4. CONNECTION OF AIR CONDITIONER
HARNESS
A vehicle just delivered has its air conditioner har-
ness disconnected to protect the air conditioner
compressor. Connect the harness as shown in the
figure.
5. CHECK THE DOORS FOR LOCK/UN-
LOCK AND OPEN/CLOSE OPERATIONS.
1) Using the key, lock and unlock the door several
times to check for normal operation. Open and
close the door several times for smooth movement.Tire sizeTire inflation pressure

Check the keyless entry system operations as fol-
lows:
 Fully open all the door windows.
 Remove the key from the ignition switch and
close all the doors including rear gate.
 Press the “LOCK” button on the keyless transmit-
ter once and check if all the doors are locked, and
the hazard light flashes once.
 Press the “UNLOCK” button on the keyless
transmitter once and check if the all doors are un-
locked, and the hazard light flashes twice. Close all doors and rear gate, press the “LOCK”
button of the keyless transmitter. Press the “UN-
LOCK” button of the keyless transmitter and wait
for 30 seconds. Check that all doors and the rear
gate are automatically locked again.
22.SEAT
Check that each seat provides full functionality in
sliding and reclining. Check all available functions
of the rear seat.
23.SEAT BELT
Pull out the seat belt and then release it. Check that
the belt webbing retracts smoothly.
24.WHEEL ALIGNMENT
Check the wheel alignments. Alignment.>
25.TEST MODE CONNECTORS
Turn the ignition switch to ON and check that the
malfunction indicator light starts blinking. If the light
blinks, return the ignition key to LOCK and discon-
nect the test mode connector. Then, turn the igni-
tion key to ON again. If the malfunction indicator
light blinks at that time in spite of the disconnected
test mode connector, carry out an engine diagno-
sis.
26.STARTING CONDITION
Start the engine and check that the engine starts
smoothly. If any battery voltage problems are
found, recharge or replace the battery. If any nois-
es are observed, immediately stop the engine and
check and repair the necessary components.
