Vehicle status information and indicators
■
Display items
 Odometer Displays the total distance the vehicle has
been driven.
 Trip meter A/trip meter B Displays the distance the vehicle has been
driven since the meter was last reset. Trip
meters A and B can be used to record and
display different distances independently.
 Distance until next engine oil
change Displays the distance the vehicle can be
driven until an oil change is necessary.
■
Changing the display
Each time the “ODO TRIP” switch is
pressed, the displayed item will be changed. When the trip meter is dis-
played, pressing and holding the switch
will reset the trip meter.
■
Pop-up display
Distance until the next engine oil
change will displayed when a warning
message indicating that oil mainte-
nance should be performed soon or is
required is displayed.
The brightness of the instrument panel
lights can be adjusted.
1 Darker
2 Brighter ■
Brightness of the meters (day mode and
night mode)
The brightness of the meters changes
between day mode and night mode.
●
Day mode: When the tail lights are off or WARNING
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE■
To prevent damage to the engine and
its components●
Do not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed.●
The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( → P.453)

Engine speed
On hybrid vehicles, engine speed is pre-
cisely controlled in order to help improve
fuel efficiency and reduce exhaust emis-
sions etc.
There are times when the engine speed that
is displayed may differ even when vehicle
operation and driving conditions are the
same. ■
Hybrid System Indicator is displayed
when
The Hybrid System Indicator is displayed in
the following situations: ●
The shift position is in D or M.●
The driving mode is other than sport
mode.■
Outside temperature display●
In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds
(less than 12 mph [20 km/h])
• When the outside temperature has
changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●

The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the information display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.

Driving NOTICE■
When driving the vehicle●
Do not depress the accelerator and
brake pedals at the same time during
driving, as this may restrain the hybrid
system output.●
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 position to P. Failure to do so
may cause the vehicle to move or the
vehicle may accelerate suddenly if the
accelerator pedal is accidentally
depressed. ■
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.
■
If you get a flat tire while driving
A flat or damaged ti re may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●

Information on what to do in case of a flat
tire ( → P.442) ■
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, hybrid
transmission, transfer (AWD models),
differential, etc. ●
Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.
If the shift control system is damaged by
flooding, it may not be possible to shift
the shift position to P, or from P to other
positions. In this case, contact your Lexus
dealer.
■
When parking the vehicle
Always set the parking brake, and shift
the shift position to P. Failure to do so
may cause the vehicle to move or the
vehicle may accelerate suddenly if the
accelerator pedal is accidentally
depressed.

3094-6. Driving tips
LS500h_OM_OM50F42U_(U) 4
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 rear tires. *
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires. *
: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.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. ■
When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height
control of the electronically modulated
air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. ( → P.301)■
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 LTA (Lane Tracing Assist)
system. (if equipped)
●
Do not use LKA (Lane-Keeping
Assist) system. (if equipped)
