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)
may differ from that shown in the illustra-
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
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.

231-1. For safe use

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.103)
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.103)
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.42)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
( P.109, 110)
For safe driving
For safe driving, adjust the seat and
mirror to an appropriate position
before driving.
Correct driving posture
WARNING
■For safe driving
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.
A
B
C
●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.
Correct use of the seat belts

571-4. Theft deterrent system
1
For safety and security
1-4.Theft deterrent system
The indicator light flashes after the
engine switch has been turned off to
indicate that the system is operating.
The indicator light stops flashing after
the engine switch has been turned to
ACCESSORY or IGNITION ON
mode to indicate that the system has
been canceled.
■System maintenance
The vehicle has a maintenance-free type
engine immobilizer system.
■Conditions that may cause the system to
malfunction
●If the grip portion of the key is in contact
with a metallic object
●If the key is in close proximity to or touch-
ing a key registered to the security sys-
tem (key with a built-in transponder chip)
of another vehicle
Engine immobilizer system
The vehicle’s keys have built-in tran-
sponder chips that prevent the
engine from starting if a key has not
been previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the
vehicle when you leave the vehicle.
This system is designed to help pre-
vent vehicle theft but does not
guarantee absolute security
against all vehicle thefts.
Operating the system
NOTICE
■To ensure the system operates cor-
rectly
Do not modify or remove the system. If
modified or removed, the proper opera-
tion of the system cannot be guaranteed.

Vehicle status information and indicators
■Rev peak (Normal mode/SPORT
S mode)
The engine speed reaches or exceeds
3600 rpm, an afterimage of the
tachometer will be displayed at the
highest engine speed for approxi-
mately 1 second.
■Meter display and layout
If the drive mode is changed, some of
the meter displays and the gauge lay-
out will be changed. ( P.192)
■The meters and display illuminate when
The engine switch is in IGNITION ON
mode.
■Welcome illumination of the analog
speedometer
●When the driver’s door is opened, the
analog speedometer will illuminate. Then,
when the driver’s door is closed, the ana-
log speedometer will illuminate and go
off (pulsate) 3 times.
●In the following situations, the analog
speedometer will not pulsate even
though the driver’s door is opened and
closed:
• Within 60 seconds after the analog
meter pulsation completes
• Within 60 seconds of turning the engine switch off
■Variable red zone
To help protect the engine, the engine
speed is controlled by starting the red zone
of the tachometer at different engine
speeds ranging from 3700 rpm to 7300
rpm depending on the engine coolant tem-
perature. Before driv ing under extremely
high load conditions, make sure to suffi-
ciently warm up the engine.
■Eco driving meter
●The number of blue segments displayed
on the eco driving meter
decreases/increases depending on the
vehicle acceleration. Use this meter as a
guideline when you wish to drive in an
eco-friendly manner that reduces fuel
consumption.
However, on a downward grade where
the vehicle can accelerate without the
accelerator pedal being depressed, the
eco driving meter may not display the
eco-driving state correctly.
●When the shift lever is moved to P, N or
R, the segments will turn gray and the eco
driving meter will not operate.
■Dimming the analog speedometer light-
ing
The analog speedometer lighting will be
dimmed when the ambient light is bright,
such as during the daytime, and SPORT S
or SPORT S+ mode is selected.
■Outside temperature display
●In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has

 Distance
• Driving range: Displays driving range
with remaining fuel
*3, 4
•After start: Displays drive distance since
vehicle start
 Other
Blank: No item
*1:Resetting: P.75
*2: Use the displayed fuel consumption as a
reference.
*3: When only a small amount of fuel is added to the tank, the display may not
be updated.
When refueling, turn the engine switch
off. If the vehicle is refueled without
turning the engine switch off, the display
may not be updated.
*4: This distance is computed based on
your average fuel consumption. As a
result, the actual distance that can be
driven may differ from that displayed.
■Eco Driving Indicator
During Eco-friendly acceleration (Eco
driving), the Eco Driving Indicator
Light will turn on.
When the acceleration exceeds the
Zone of Eco driving, or when the vehi-
cle is stopped, the light turns off. Eco Driving Indicator will not operate
under the following conditions:

The shift lever is in any position
other than D.
 A paddle shift switch is operated.
 Neither normal mode nor Eco drive
mode is selected. ( P.192)
 The vehicle speed is approximately
80 mph (130 km/h) or higher.
■Tire pressure
 P.275
■Gear positions
Displays the current gear position
when the shift lever is in D or M.
■Vehicle sway warning
Detects the sway of the vehicle within a
lane, which is often associated with a
decrease in the driver’s attention level,
and displays the decrease in attention
using a bar display.
The shorter the bar length, the more
the driver may need to rest.
This display is a pa rt of the LDA (Lane
Departure Alert with steering control) sys-
tem. The display is en abled when the oper-
ating conditions of the vehicle sway
warning are met. ( P.165)
■Units
The units of measure used can be
changed while driving.
Unlike the units sett ing performed on ,
the units setting performed on can be
changed while driving.
