LS500_OM_(U)_1810 Displays warning messages if a malfunction occurs (  P.425)■
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.■
Liquid crystal display

Customization
The gauges and meters can be customized
on of the multi-information display.
(  P.85) ■
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.

158 4-1. Before driving
LS500_OM_(U)_1810 WARNING●
In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while the
engine is running, and apply the park-
ing brake as necessary.●
If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.●
Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.■
When the vehicle is parked●
Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter
or spray can, and may lead to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing
the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.
●
Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.
●
Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument pane l or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle. ●
Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire. ●
Always apply the parking brake, shift
the shift position to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
If the vehicle is parked with the shift
position in P but the parking brake is
not set, the vehicle may start to move,
possibly leading to an accident. ●
Do not touch the exhaust pipes while
the engine is running or immediately
after turning the engine off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, leading to death or a serious
health hazard. ■
When braking ●
When the brakes are wet, drive more
cautiously.
Braking distance in creases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
