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.
1
Insert 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.

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 driving. 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 bottom-
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.110)
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.110)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
( P.116)
Wear the seat belt correctly.
( P.25) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (
P.25)
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.46)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
( P.118, 119)

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.

Mechanical keys
Key number plate
Card key (electronic key) (if
equipped)
Operating the smart access system with

■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is stored inside
the card key should be used only if a

●If the battery cover is not installed and the
battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive terminal
facing the Lexus emblem.
■When riding in an aircraft
When bringing an electronic key onto an
aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an
electronic key in your bag etc., ensure that
the buttons are not likely to be pressed
accidentally. Pressing a button may cause
the electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
(The card key battery life is from one year
to one year and a half.)

sound in the cabin when the engine is
stopped.
●Electronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance. ( P.105)
●As the electronic key always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( P.297)
• The smart access system with push-but- ton start or the wireless remote control

mately 10 days after a new electronic key

electronic key (other than those in your
possession) has been registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject them to
strong shocks or bend them.
●Do not expose the keys to high tem-
peratures for long periods of time.

or more away from electric appliances
that are turned on. Radio waves emitted
from electric applianc es within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.
■In case of a smart access system with
push-button start malfunction or
other key-related problems
 P.330
■When an electronic key is lost
 P.329
■Handling the card key (if equipped)

drinking water, etc. is spilled on the
key, immediately remove the battery
cover and wipe the battery and termi-
nals. (To remove the battery cover,
