Vehicle status information and indicators
*4: This distance is computed based on your average fuel consumption. As a
result, the actual distance that can be
driven may differ from that displayed.
■Energy monitor
 P.99
■AWD Control
Displays the driving force applied to
each wheel using segments.
The greater the number of segments
displayed, the greater the driving force
applied.
■G-force (if equipped)
Displays lateral G-forces on the vehi-
cle. Also displays, around the periph-
ery of the G-force display, the left and
right steering amount, accelerator
pedal input, and brake fluid pressure.
Acceleration G-force on the vehi-
cle
Current G-force value (analyzed
value of front/rear and left/right
G-forces)
Record of the maximum G-forces

Brake fluid pressure
Steering amount
This display is intended for use as a guide- line. Depending on fact
ors such as the road
surface condition, temperature and vehicle
speed, the display may not show the actual
condition of the vehicle.
 Resetting the record of maximum
G-forces
Press and hold of the meter control
switch to reset the record.
Peak hold function
If lateral G-forces of 0.5 G or greater are
generated, the G-forc e value display will
turn amber and be held for 2 seconds.
■Tire pressure
 P.382
■Units (if equipped)
The units of measure used can be
changed while driving.
Unlike the units sett ing performed on the
settings display, th e units setting per-
formed on the drive information display
can be changed while driving.
■Blank (No items)
Displays no drive information contents.
■G-force display (if equipped)
●The G-force values may not be zero even
when the vehicle is parked, such as when
it is parked on an incline.
●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 12-volt battery terminal is discon-
nected and reconnect ed, the steering
amount display may be disabled tempo-
rarily. After driving th e vehicle for a while,
the display will be enabled.
■Tire pressure
• It may take a few minutes to display the tire inflation pressu re after the power

Driving
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect
the condition of the 12-volt battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires ar e of the specified size
and the same brand, and that chains match
the size of the tires.
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
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.
Pre-winter preparations
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.
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use the LTA (Lane Tracing
Assist) system.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow
tires from your Lexus dealer 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.
