CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with
the pedals 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 vehi-
cles, 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) 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 clean-
ing the floor.
With the hybrid system 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 6 4 )
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. 164)
Lock the head restraint in place with the center of the head restraint
closest to the top of your ears. (P. 173)
Wear the seat belt correctly. (P. 38)
Make sure that all occupants are wearing their seat belts before driving
the vehicle. (P. 3 8 )
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt. (P. 6 1 )
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. 178, 180)
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
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.
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 immediately.

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 prop-
erly.
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 serious 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
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10
in.) distance, 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.

CAUTION
SRS airbag precautions
Do not hang coat hangers or hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the
SRS curtain shield airbags deploy.
If a vinyl cover is put on the area where the SRS knee airbag will deploy, be
sure to remove it.
Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags. Such accessories
may prevent the side airbags from activating correctly, disable the system or
cause the side airbags to inflate accidentally, resulting in death or serious
injury.
Do not allow anyone to kneel on the pas-
senger seats toward the door or put their
head or hands outside the vehicle.
Do not attach anything to or lean any-
thing against areas such as the dashboard,
steering wheel pad and lower portion of
the instrument panel.
These items can become projectiles when
the SRS driver, front passenger and knee
airbags deploy.
Do not attach anything to areas such as a
door, windshield glass, side door glass,
front or rear pillar, roof side rail and assist
grip. (Except for the speed limit sticker

When the sensors located at the back of the front bumper detect an impact
with a body, such as a pedestrian, which meets or exceeds the threshold
level while the vehicle is being driven within the operational speed range,
the system becomes operational and raises the rear portion of the hood.
Sensors

Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the
Pop Up Hood system raises the rear portion of the hood to reduce the
possibility of a serious impact to the pedestrian’s head area by adding
clearance to the engine compartment.

Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
The accelerator pedal is released while driving with the shift lever in D or S.
The brake pedal is depressed while driving with the shift lever in D or S.
EV indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
During gasoline engine warm-up
During hybrid battery (traction battery) charging
When the temperature of the hybrid battery (traction battery) is high or low
When the heater is switched on
Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery
does not need to be charged from an outside source. However, if the vehicle is
left parked for a long time the hybrid battery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes or 16 km (10 miles). If the hybrid battery becomes fully discharged and
you are unable to jump-start the vehicle with a 12-volt battery, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always shift the shift lever to P when the vehicle is stopped. When driving in
heavy traffic, operate the vehicle with the shift lever in D or S to avoid dis-
charging the battery.
Charging the 12-volt battery
P. 552 The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or the gasoline engine is
stopped.
