221-1. For safe use
1-1.For safe use
Use only floor mats designed specifi-
cally for vehicles of the same model
and model year as your vehicle. Fix
them securely in place onto the carpet.
1Insert the retaining hooks (clips)
into the floor mat eyelets.
2 Turn the upper knob of each retain-
ing hook (clip) to secure the floor
mats in place.
Always align the marks .
The shape of the reta ining hooks (clips)

tion.
Before driving
Observe the following before start-
ing off in the vehicle to ensure
safety of driving.
Installing floor mats
A
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s
floor mat to slip, poss ibly interfering with
the pedals while driv ing. An unexpect-
edly high speed may result or it may
become difficult to stop the vehicle. This
could lead to an accident, resulting in
death or 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 Genu-
ine floor mats.
●Only use floor mats designed for the
driver’s seat.
●Always install the floor mat securely
using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on
top of each other.
●Do not place the floor mat bot-
tom-side up or upside-down.
■Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this
check after cleaning the floor.
●With the engine stopped and the shift
position in P, fully depress each pedal
to the floor to make sure it does not
interfere with the floor mat.

231-1. For safe use
1
For safety and security
Adjust the angle of the seatback so
that you are sitting straight up and
so that you do not have to lean for-
ward to steer. (P.121)
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.121)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
( P.138)
Wear the seat belt correctly.
( P.24) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (
P.24)
Use a child restraint system appropri-
ate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. ( P.45)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
( P.142, 143, 151)
For safe driving
For safe driving, adjust the seat and
mirror to an appropriate position

Correct driving posture
WARNING
■For safe driving
Observe the following precautions.
Failure to do so may result in death or
serious injury.
A
B
C
D
●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 pos-
ture from being achieved, and reduce
the effectiveness 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 mechanism may
also be damaged.
●Always observe the legal speed limit
when driving on public roads.
●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 con-
tinue driving and take a break immedi-
ately.
