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.)●
When “--” or “E” is displayed, the system
may be malfunctioning. Take your vehicle
to your Lexus dealer.■

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.WARNING■
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 in formation 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.
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.443)

Rev indicator
When the engine speed reaches a set
speed or the red zone, a ring-shaped
indicator ( ) will be displayed on the

mately 1 second. ■

1694-2. Driving procedures
LS500_OM_OM50F54U_(U) 4
Driving When vehicle speed drops (down-
shift only).
When it is necessary to protect the
engine or automatic transmission
when the engine coolant tempera-
ture is low, the automatic transmis-
sion fluid temperature is high or low,
or other reasons.
Also, the gear will not shift when the
vehicle speed is low, even if an upshift
operation is performed. ■
Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the paddle shift switch is operated. (A
buzzer will sound twice.)
1 Right turn
2 Lane change to the right (move the
lever partway and release it) The right hand signals will flash 3 times.
3 Lane change to the left (move the
lever partway and release it) The left hand signals will flash 3 times.
4 Left turn ■
Turn signals can be operated when
The engine switch is in IGNITION ON
mode.
■
If the indicator flashes faster than usual
Check that a light bulb in the front or rear
turn signal lights has not burned out.
■
If the turn signals stop flashing before a
lane change has been performed
Operate the lever again.Turn signal lever

Driving 4-6.Driving tips
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 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.293)■
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)

■
Coolant selection
Only use “Toyota Super Long Life Coolant”
or a similar high quality ethylene glycol
based non-silicate, non-amine, non-nitrite,
and non-borate coolant with long-life
hybrid organic acid technology.
U.S.A.:
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. (Minimum temperature: -31°F
[-35°C])
Canada:
“Toyota Super Long Life Coolant” is a mix-
ture of 55% coolant and 45% deionized
water. (Minimum temperature: -44°F
[-42°C])
For more details about coolant, contact
your Lexus dealer. ■
If the coolant level drops within a short
time of replenishing
Visually check the radi ator, hoses, engine
coolant reservoir caps, drain cock and
water pump.
If you cannot find a leak, have your Lexus
dealer test the cap and check for leaks in
the cooling system.
Check the radiator, condenser, inter-
cooler radiator and intercooler sub
radiator and clear away any foreign
objects. If either of the above parts is
extremely dirty or yo u are not sure of
their condition, have your vehicle
inspected by your Lexus dealer.B

When the engine is hot
Do not remove the engine coolant reser-
voir cap, the intercooler coolant reser-
voir cap and the coolant inlet cap.
( → P.445)
The cooling system may be under pres-
sure and may spray hot coolant if the cap
is removed, causing serious injuries, such
as burns.
NOTICE■
When adding coolant
Coolant is neithe r plain water nor
straight antifreeze. The correct mixture
of water and antifreeze must be used to
provide proper lubrication, corrosion
protection and cooling. Be sure to read
the antifreeze or coolant label.
■
If you spill coolant
Be sure to wash it off with water to pre-
vent it from damaging parts or paint.
Checking the radiator, con-
denser, intercooler radiator (if
equipped) and intercooler sub
radiator (if equipped)
