CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the ped-
als while driving. An unexpectedly high speed may result or it may become difficult to
stop the vehicle, leading to an accident, or leading to death or a serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year vehicles,
even if they are Lexus Genuine floor mats.
●Only use floor mats designed for the driver’s seat.
●Always install the floor mat securely using the retaining hooks (clips) provided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
●Check that the floor mat is securely fixed in
the correct place with all the provided retain-
ing hooks (clips). Be especially careful to per-
form this check after cleaning the floor.
●With the engine stopped and the shift lever in
P, fully depress each pedal to the floor to
make sure it does not interfere with the floor
mat.

Adjust the angle of the seatback so
that you are sitting straight up and so
that you do not have to lean forward
to steer. (→P. 1 4 7 )
Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the elbow
when gripping the steering wheel.
(→P. 1 4 7 )
Lock the head restraint in place with the center of the head restraint closest to
the top of your ears. (→P. 1 5 6 )
Wear the seat belt correctly. (→P. 36)
Make sure that all occupants are wearing their seat belts before driving the vehi-
cle. (→P. 3 6 )
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt. (→P. 5 8 )
For safety drive
For safe driving, adjust the seat and mirror to an appropriate position before
driving.

Make sure that you can see backward clearly by adjusting the inside and outside
rear view mirrors properly. (→P. 161, 163)
Adjusting the mirrors
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat belt and head restraint.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism may also be damaged.
●When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while driving, do not force yourself to continue driving
and take a break immediately.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They work
together with the seat belts to help reduce the risk of death or serious injury.

The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. As the airbags deploy, a chemical reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the occupants.
When the Pop Up Hood is activated, a non-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: →P. 5 4 )

CAUTION
■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 seri-
ous injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) from your driver airbag provides 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 250 mm (10 in.) 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 com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the way forward, simply 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 airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommended above, while still maintaining control
of the foot pedals, steering wheel, and your view of the instrument panel controls.
