CAUTION
■SRS airbag precautions
●If a vinyl cover is put on the area where the SRS knee airbags 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 inflat ion of the airbags. Such accessories may
prevent the side airbags from activating co rrectly, disable the system or cause the
side airbags to inflate accidentally, resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door
or window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off
any residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by
your Lexus dealer.
●Do not attach anything to or lean anything
against areas such as the dashboard, steer-
ing 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.
●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.

2-1. Driving procedures

When driving
Starting off on a steep uphillMake sure that the pa rking brake is set secu rely, and then select
shift position D.
Check that the shift position indicator shows D.
Gently depress the accelerator pedal.
Release the parking brake.
■Driving in the rain
●Drive carefully when it is raining, becaus e visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, be cause 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 th e tires and the road surface, preventing
the steering and brakes from operating properly.
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 994 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• 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 sys-
tem needs bedding-down of the brake shoes periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down operation.

2-1. Driving procedures
CAUTION
●Do not select shift position R when the vehicle is rolling forward, do not select D
when moving in reverse, and do not press the P position switch before the vehicle
stops fully. Doing so will cause the buzzer to sound and the shift position to
change to N. In addition, excessive forc e will be applied to the powertrain and
damage may result.
●Do not change the shift position to N while the vehicle is moving.
Doing so may cause insufficient engine braking, resulting in an accident.
●Do not turn the hybrid system off while driving.
The power steering and brake actuator will not operate properly if the hybrid sys-
tem is off.
●Use engine braking (shift position B) to maintain a safe speed when driving down
a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. ( P. 1 5 5 )
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their body are not
outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steer ing may cause tire slippage and reduce
your ability to control the vehi cle, resulting in an accident.
●Abrupt changes from shift position D to B and rapid changes in the engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a pudd le, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on on ly one side are wet and not functioning
properly, steering control may be af fected, resulting in an accident.

2-1. Driving procedures
NOTICE
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire. ( P. 5 2 7 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of engine oil, transaxle fluid for the hybrid system
etc.
●Lubricant condition for the bearings and suspension joints (where possible), and
the function of all joints, bearings, etc.
As flooding may damage components involv ed in P position control, the parking
lock may jam in the locked position.
■If the vehicle will not shift out of the P position
There is a possibility that the 12-volt batt ery is discharged. Check the 12-volt battery
in this situation.
