●
If window tint with a metallic content or metallic objects are attached to
the rear window
● Vehicles with AUTO ACCESS SEAT: If the wireless remote control of the
AUTO ACCESS SEAT is operated simultaneously, the AUTO ACCESS
SEAT may not operate properly.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.
■ Notes for the entry function
●Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, floor or in the glove box when the engine is started or “ENGINE START STOP” switch modes
are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave
reception conditions, it may be detected by the antenna outside the cabin
and the door will become lockable from the outside, possibly trapping the
electronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone. However, only the doors detecting the
electronic key can be used to unlock the vehicle.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the electronic key
is within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the smart key system. (Use the wireless remote control to
unlock the doors.)
● If power slide door is unable to operate due to prohibition by the power
sliding door main switch, the door unlock and open operation will not be
performed. ( P. 70)

SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you sit less than 10 in.
(250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the pedals comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, sim-
ply by reclining the back of the seat somewhat. If reclining the back of
your seat makes it hard to see the road, raise yourself by using a firm,
non-slippery cushion, or raise the seat if your vehicle has that feature\
.
• If your steering wheel is adjustable, tilt it downward. This points the air- bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while
still maintaining control of the foot pedals, steering wheel, and your view of
the instrument panel controls.

CAUTION
■SRS airbag precautions
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when SRS driver, front passenger and
knee airbags deploy.
● Do not attach anything to areas such as
the door, windshield glass, side door
glass, front or side pillars, roof side rail
and assist grip.
● Vehicles without a smart key system:
Do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
SRS knee airbag inflation or be thrust
into the driver’s seat area by the force
of the deploying airbag, thus causing a
danger.
