1401-8. Safety information
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 properly.
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. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) 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 10 in. (250 mm) 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 dr ivers can achieve the 10 in. (250 mm)
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, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

2642-4. Using other driving systems
■
Flicker effect
When the camera is used under fluorescent light, sodium lights, or mercury lights
etc., the lights and the illuminated areas may appear to flicker.
CAUTION■
When using the rear view monitor system, observe the following precautions to
avoid an accident that could result in death or serious injuries: ●
Never depend solely on the monitor system when reversing.●
Always check visually and with the mirrors to confirm your intended path is clear.●
Use your own eyes to confirm the vehicle’s surroundings, as the displayed image
may become faint or dark, and moving imag es will be distorted, or not entirely
visible when the outside temperature is low. When backing up, be sure to check
behind and all around the vehicle visually and with the mirrors before proceeding.●
Always check the vehicle surrounding area, because the guide lines are ancillary
lines.●
The guide lines are ancillary lines and do not change even if the steering wheel is
turned.●
Depicted distances between objects and flat surfaces differ from actual dis-
tances.●
Do not use the system if the back door is open.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning co mputer and the tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (  P. 6 7 3 )
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
● When rotating the tires
● When the tire inflation pressure is changed such as when changing
travelling speed or load weight
● When changing the tire size
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detec t low tire infla-
tion pressure before serious problems arise. (  P. 7 3 6 )

7405-2. Steps to take in an emergency
●
If non-genuine Lexus wheels are used (Even if you use Lexus wheels, the tire
pressure warning system may not work properly with some types of tires.)●
If tire chains are used●
Vehicles with a full-size spare tire: If the spare tire is in a location subject to poor
radio wave signal reception●
Vehicles with a full-size spare tire: If a large metallic object which can interfere
with signal reception is pu t in the luggage compartment■
If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute
when the “POWER” switch is turned to ON mode, have it checked by your Lexus
dealer.■
Customization
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features  P. 825)
CAUTION■
When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate using more force than usual.■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury. ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.●
If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest Lexus dealer.
●
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.
■
If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

When trouble arises
7735-2. Steps to take in an emergency
■
If you have a flat front tire on a road covered with snow or ice (vehicles with a
compact spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the
following steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehi-
cle.
Fit tire chains to the front tires.■
After completing the tire change
The tire pressure warning system must be reset. (  P. 6 7 1 )
CAUTION■
Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury. ●
Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.●
Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do no t use other tire jacks for replacing tires
on this vehicle.●

Do not put any part of your body under the vehicle while it is supported by the
jack.●
Do not start or run the hybrid system while your vehicle is supported by the jack.●
Do not raise the vehicle while someone is inside.●
When raising the vehicle, do not put an object on or under the jack.
●
Do not raise the vehicle to a height greate r than that required to replace the tire.
●
