When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for the child restraint system installa-
tion.
When a junior seat is installed, always ensure that the shoulder belt is
positioned across the center of the child's shoulder. The belt should be
kept away from the child's neck, but not so that it could fall off the child's
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, choking or other serious injuries may result
in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
Make sure the outside rear seat head restraints are not in the folded posi-
tion.
Ensure that the belt and tab are securely locked and the seat belt is not
twisted.
Push and pull the child seat from side to side and forward to be sure it is
secure.
Follow all installation instructions provided by the child restraint system
manufacturer.
Never use a rear-facing child restraint
system on the front passenger seat
when the airbag manual on-off switch
is on.
(P. 135)
The force of the rapid inflation of the
front passenger airbag can cause death
or serious injury to children in the
event of an accident.
A warning label on the passenger side
instrument panel reminds you not to
install a rear-facing child restraint sys-
tem on the front passenger seat

CAUTION
To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint. Make sure the child restraint system is securely attached, or it may
cause death or serious injury to the child or other passengers in the event of
a sudden stop, sudden swerve or an accident.

CAUTION
When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as long
as the airbag manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system 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.

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 )

When starting off
To prevent the vehicle from creeping forward, keep the brake pedal firmly
depressed when shifting the shift lever.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly, allowing you to depress the brake and accelerator
pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
Do not drive the vehicle over or stop the vehicle near flammable materi-
als.
Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the trunk is closed. Large amounts of exhaust in the vehicle can
cause driver drowsiness and an accident, resulting in death or a serious
health hazard. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, immedi-
ately.
Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
