WARNING
■General precautions while driving
Driving under the infl uence: Never drive
your vehicle when un der the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment and reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mistakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

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
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.
