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, possibly 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.

Q

When installing the driver’s floor mat

O

Do not use floor mats designed for 

other models or different model year 

vehicles, even if they are Lexus 

Genuine floor mats.

O

Only use floor mats designed for the 

driver’s seat.

O

Always install the floor mat securely 

using the retaining hooks (clips) pro-

vided.

O

Do not use two or more floor mats on 

top of each other.

O

Do not place the floor mat bottom-

side up or upside-down.

Q

Before driving

O

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.

O

Do not adjust the position of the 

driver’s seat while driving.

Doing so could cause the driver to lose 

control of the vehicle.

O

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.

O

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.

O

Always observe the legal speed limit 

when driving on public roads.

O

When driving over long distances, 

take regular breaks before you start to 

feel tired. Also, if you feel tired or

wearing their seat belts before driv-
ing the vehicle.

WARNING

Observe the following precautions to 

reduce the risk of injury in the event of 

sudden braking, sudden swerving or an 

accident. 

Failure to do so may cause death or seri-

ous injury.

Q

Wearing a seat belt

O

Ensure that all passengers wear a seat 

belt.

O

Always wear a seat belt properly.

O

Each seat belt should be used by one 

person only. Do not use a seat belt for 

more than one person at once, includ-

ing children.

O

Lexus recommends that children be 

seated in the rear seat and always use 

a seat belt and/or an appropriate child 

restraint system.

O

To achieve a proper seating position, 

do not recline the seat more than nec-

essary. The seat belt is most effective 

when the occupants are sitting up 

straight and well back in the seats.

O

Do not wear the shoulder belt under 

your arm.

O

Always wear your seat belt low and 

snug across your hips.

Q

Pregnant women

Obtain medical advice and wear the seat 

belt in the proper way. (



P.33)

Women who are pregnant should posi-

tion the lap belt as low as possible over 

the hips in the same manner as other 

occupants, extending the shoulder belt 

completely over the shoulder and avoid-

ing belt contact with the rounding of the 

abdominal area.
If the seat belt is not worn properly, not 

only the pregnant woman, but also the 

fetus could suffer death or serious injury 

as a result of sudden braking or a colli-

sion.

seat belt until it is replaced. Damaged 

seat belts cannot protect an occupant 

from death or serious injury.

O

Ensure that the belt and plate are 

locked and the belt is not twisted.

If the seat belt does not function cor-

rectly, immediately contact any autho-

rized Lexus retailer or Lexus 

authorized repairer, or any reliable 

repairer.

O

Replace the seat assembly, including 

the belts, if your vehicle has been 

involved in a serious accident, even if 

there’s no obvious damage.

O

Do not attempt to install, remove, 

modify, disassemble or dispose of the 

seat belts. Have any necessary repairs 

carried out by any authorized Lexus 

retailer or Lexus authorized repairer, 

or any reliable repairer. Inappropriate 

handling may lead to incorrect opera-

tion.

Q

Emergency locking retractor (ELR)

The retractor will lock the belt during a sud-

den stop or on impact. It may also lock if you 

lean forward too quickly. A slow, easy 

motion will allow the belt to extend so that 

you can move around fully.

button .

2

Push the seat belt shoulder anchor 
up.

Move the height adjuster up and down as 
needed until you hear a click.

The pretensioners help the seat belts to 
quickly restrain the occupants by 
retracting the seat belts when the vehi-
cle is subjected to certain types of 
severe frontal or side collision.

The pretensioners do not activate in the 
event of a minor frontal impact, a minor 
side impact, a rear impact or a vehicle roll-
over.

Q

Replacing the belt after the preten-

sioner has been activated

If the vehicle is involved in multiple colli-

sions, the pretensioner will activate for the 

first collision, but will not activate for the 

second or subsequent collisions.

Q

PCS-linked seat belt pretensioner con-

trol

If the PCS (Pre-Collision System) deter-

mines that the possibility of a collision with a 

vehicle is high, the seat belt pretensioners 

will be prepared to operate.

tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemical 
reaction in the inflators quickly fills the airbags with non-toxic gas to help restrain 
the motion of the occupants.

Q

If the SRS airbags deploy (inflate)

O

Slight abrasions, burns, bruising etc., may 

be sustained from SRS airbags, due to the

tion) by hot gases.

O

A loud noise and white powder will be 

emitted.

O

Parts of the airbag module (steering 

wheel hub, airbag cover and inflator) as 

well as the front seats, parts of the front 

and rear pillars, and roof side rails, may 

be hot for several minutes. The airbag 

itself may also be hot.

• An SRS airbag is deployed.

• A seat belt pretensioner is activated.

• The vehicle is involved in a severe rear-

end collision.

Q

SRS airbag deployment conditions (SRS 

front airbags)

O

The SRS front airbags will deploy in the 

event of an impact that exceeds the set 

threshold level (the level of force corre-

sponding to an approximately 20 - 30 

km/h [12 - 18 mph] frontal collision with a 

fixed wall that does not move or deform).

However, this threshold velocity will be 

considerably higher in the following situ-

ations:

• If the vehicle strikes an object, such as a 

parked vehicle or sign pole, which can 

move or deform on impact

• If the vehicle is involved in an underride 

collision, such as a collision in which the 

front of the vehicle underrides, or goes 

under, the bed of a truck

O

Depending on the type of collision, it is 

possible that only the seat belt preten-

sioners will activate.

Q

SRS airbag deployment conditions (SRS 

side and curtain shield airbags)

O

The SRS side and curtain shield airbags 

will deploy in the event of an impact that 

exceeds the set threshold level (the level 

of force corresponding to the impact 

force produced by an approximately 

1500 kg [3300 lb.] vehicle colliding with 

the vehicle cabin from a direction per-

pendicular to the vehicle orientation at an 

approximate speed of 20 - 30 km/h [12 - 

18 mph]).

O

Both SRS curtain shield airbags may 

deploy in the event of a severe side colli-

sion.

O

Both SRS curtain shield airbags may also 

deploy in the event of a severe frontal 

collision.

Q

Conditions under which the SRS air-

bags may deploy (inflate), other than a 

collision

The SRS front airbags and SRS curtain 

shield airbags may also deploy if a serious 

impact occurs to the underside of your 

vehicle. Some examples are shown in the 

illustration.

WARNING

O

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 air-

bag 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 breast-

bone. 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 recom-

mended above, while still maintaining 

control of the foot pedals, steering wheel, 

and your view of the instrument panel 

controls.

O

The SRS front passenger airbag also 

deploys with considerable force, and 

can cause death or serious injury 

especially if the front passenger is very 

close to the airbag. The front passen-

ger seat should be as far from the air-

bag as possible with the seatback 

adjusted, so the front passenger sits 

upright.

O

Improperly seated and/or restrained 

infants and children can be killed or 

seriously injured by a deploying air-

bag. An infant or child who is too small 

to use a seat belt should be properly 

secured using a child restraint system. 

Lexus strongly recommends that all 

infants and children be placed in the 

rear seats of the vehicle and properly 

restrained. The rear seats are safer for 

infants and children than the front pas-

senger seat. (



P.46)

O

Do not sit on the edge of the seat or 

lean against the dashboard.

O

Do not allow a child to stand in front of 

the SRS front passenger airbag unit or 

sit on the knees of a front passenger.

O

Do not allow the front seat occupants 

to hold items on their knees.

O

Do not lean against the door, the roof 

side rail or the front, side and rear pil-

lars.

WARNING

O

Do not allow anyone to kneel on the 

passenger seat toward the door or put 

their head or hands outside the vehi-

cle.

O

Do not attach anything to or lean any-

thing against areas such as the dash-

board, 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.

O

Do not attach anything to areas such 

as a door, windshield, side window, 

front or rear pillar, roof side rail and 

assist grip. (Except for the speed limit 

label 



P.448)

O

Do not hang coat hangers or other 

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.

O

If a vinyl cover is put on the area where 

the SRS knee airbag will deploy, be 

sure to remove it.

O

Do not use seat accessories which 

cover the parts where the SRS side air-

bags inflate as they may interfere with 

inflation of the SRS airbags. Such

Q

When installing a child restraint sys-

tem

For safety reasons, always install a child 

restraint system in a rear seat. In the

the front seat can be used as long as the 

airbag manual on-off system is set to 

“OFF”.

WARNING

Q

When a child restraint system is not 

installed on the front passenger seat

Ensure that the airbag manual on-off sys-

tem is set to “ON”.

If it is left off, the airbag may not deploy in 

the event of an accident, which may 

result in serious injury or even death.

Riding with children

Observe the following precautions 
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child 
becomes large enough to properly 
wear the vehicle’s seat belt.



It is recommended that children 
sit in the rear seats to avoid acci-
dental contact with the shift lever, 
wiper switch, etc.



Use the rear door child-protector 
lock or the window lock switch to 
avoid children opening the door 
while driving or operating the 
power window accidentally. 
(

P.181, 210)



Do not let small children operate 
equipment which may catch or 
pinch body parts, such as the 
power window, hood, back door, 
seats, etc.

WARNING

Q

When children are in the vehicle

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 tempera-

tures inside the vehicle can be fatal to 

children.
