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 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.
NOTICE
■To prevent damage to the engine and
its components
●Do not let the indicator of the tachom-
eter enter the red zone, which indi-
cates 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.410)

(Take care to ensure that the key is not
stolen.)
• Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.125)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a buzzer may sound outside the
vehicle and “Key Detected in Vehicle”
may be shown on the multi-information
display. To turn off the alarm, lock all the
doors.

Vehicle specifications
0W-20 oil may be used. However, it
must be replaced with SAE 0W-16 at
the next oil change.Outside temperature
Oil viscosity (0W-16 is explained here
as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which allows
cold startability. Oils with a lower
value before the W allow for easier
starting of the engine in cold
weather. • The 16 in 0W-16 indicates the vis-
cosity characteristic of the oil when
the oil is at high temperature. An oil
with a higher viscosity (one with a
higher value) may be better suited if
the vehicle is operated at high
speeds, or under extreme load con-
ditions.
How to read oil container label:
API registered marks is added to some
oil containers to help you select the oil
you should use.
*: The coolant capacity is a reference quantity. If replacement is necessary, contact your Lexus dealer.
