play only)
If lateral G-forces of 0.5 G or greater are
generated, the G-force value displayed on
the sub-content displa y area will turn yel-
low and be held for 3 seconds.
■Rear wing position (vehicles with
an active rear wing)
Displays the raised/retracted state of
the active rear wing
■Using the lap timer
If the engine is stopped while a lap is being
timed, the lap timer will stop and the lap
time up to that point will be recorded.
■Torque distribution display (if equipped)
Torque distribution may not be displayed
correctly in some cases, such as when the
vehicle passes over road expansion joints.
■G-force display
●The G-force values may not be zero even
when the vehicle is parked, such as when
it is parked on an incline.
●The steering amount, accelerator pedal
input, and brake fluid pressure displays
are disabled until the engine has warmed
up (the variable red zone of the tachome-
ter has retracted to 7300 rpm).
After the engine has warmed up, these
displays will be enabled.
●Depending on the vehicle usage condi-
tions, the brake fluid pressure display may
not reach its maximum reading even
though the brake pedal is fully depressed.
●If a battery terminal is disconnected and
reconnected, the steeri ng amount display
may be disabled temporarily. After driv-
ing the vehicle for a while, the display will
be enabled.

Driving
NOTICE
●Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill.
■When parking the vehicle
●Always set the parking brake and shift
the shift lever to P. Failure to do so may
cause the vehicle to move or the vehi-
cle may accelerate suddenly if the
accelerator pedal is accidentally
depressed.
●Vehicles with titanium mufflers: Be
careful when parking in a parking spot
with anything protruding from the sur-
face, such as a multi-level parking sys-
tem, as the protruding area may
contact and damage the muffler.
■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
damaging the wheels, underside of the
vehicle, etc.
●Vehicles with titanium mufflers: As the
vehicle’s ground clearance is low,
when driving over bumps or areas
where the road height changes, drive
as slowly as possible to avoid damag-
ing the muffler.
■If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●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.313, 319)
■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 vehi-
cle:
●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 fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, differential, etc.
●Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.
■Precaution for CCB (Carbon
Ceramic Brake) discs (if equipped)
Be careful not to subject the CCB discs
to any kind of strong impact.
Even if there is no obvious damage, in the
following situations, have the vehicle
inspected by your Lexus dealer:

Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires.
Ensure that all tires are the specified size
and the same brand.
Perform the following according to the
driving conditions:
Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attach-
ment of snow tires affects the operation
of the tire pressure warning valves and
transmitters.
