If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the anti-theft system automatically locks the vehicle again.
Alarms and warning indicators
A combination of exterior and interior alarms as well as warnings displayed

Impact detection door lock release system
In the event that the vehicle is subject to a strong impact, all the doors are
unlocked. Depending on the force of the impact or the type of accident,
however, the system may not operate.
Using the mechanical key
The doors can also be locked and unlocked with the mechanical key. (P.
458)
Customization that can be configured at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional
Settings (e.g. unlocking function using a key) can be changed.
(Customizable features P. 484)
CAUTION
To prevent an accident
Observe the following precautions while driving the vehicle.
Failing to do so may result in a door opening and an occupant falling out,
resulting in death or serious injury.
Always use a seat belt.
Ensure that all doors are properly closed.
Do not pull the inside handle of the doors while driving.
The doors may be opened and the passengers may be thrown out of the
vehicle, resulting in death or serious injury.
Be especially careful for the front doors, as the doors may be opened even
if the inside lock buttons are in locked position.
Set the rear door child protector locks when children are seated in the rear
seat.

Removing the head restraints (rear seats)
Adjusting the height of the head restraints
When using the rear seat head restraints
Make sure the head restraints are not in the stowed/folded position while in
use.
CAUTION
Head restraint precautions
Observe the following precautions regarding the head restraints. Failure to
do so may result in death or serious injury.
Use the head restraints designed for each respective seat.
Adjust the head restraints to the correct position at all times.
After adjusting the head restraints, push down on them and make sure
they are locked in position.
Do not drive with the head restraints removed.
Pull the head restraint up while pushing
both of the lock release buttons.

Make sure that the head restraints are
adjusted so that the center of the head
restraint is closest to the top of your ears.

If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel, airbag cover and inflator) as
well as the front seats, and parts of the front pillar, rear pillar and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
The windshield may crack.
SRS airbag deployment conditions (front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 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 if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if the vehicle is involved in an underride collision
(e.g. a collision in which the front of the vehicle “underrides”, or goes
under, the bed of a truck, etc.).
It is possible that in some collisions where the forward deceleration of
the vehicle is very close to the designed threshold level, the SRS front
airbags and the seat belt pretensioners may not activate together.
SRS airbag deployment conditions (side and curtain shield airbags)
The SRS side airbags and SRS 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 perpen-
dicular to the vehicle orientation at an approximate speed of 20 - 30 km/h
[12 - 18 mph]).

CAUTION
SRS airbag precautions
Observe the following precautions regarding the 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.
Since the risk zone for driver airbag is the first 50 - 75 mm (2 - 3 in.) of
inflation, placing yourself 250 mm (10 in.) from your driver airbag pro-
vides 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 maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.

CAUTION
SRS airbag precautions
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 passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. 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 the safest for infants and children. (P. 1 1 6 )
Do not sit on the edge of the seat or
lean against the dashboard.
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.
Do not drive the vehicle while the
driver or passenger have items resting
on their knees.

2-1. Driving procedures

When driving
IS F_EE
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be
especially slippery.
Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driv-
ing. This is due to automatic up-shifting control or down-shifting implemen-
tation to meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recom-
mended to observe:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of
brake system needs bedding-down of the brake shoes periodically or when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, perform the bedding down.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 4 7 4 )
