■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

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,

■Cautions during setting up the dis-
play
As the engine needs to be running
during setting up the display, en sure that
the vehicle is parked in a place with ade-
quate ventilation. In a closed area such as
a garage, exhaust gases including harm-
ful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to
death or a serious health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that
the engine is running while setting up the
display features.

963-2. Opening, closing and locking the doors and trunk
Trunk
The trunk can be opened using the
trunk opener, entry function or
wireless remote control.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■Before driving
●Make sure that the trunk lid is fully
closed. If the trunk lid is not fully
closed, it may open unexpectedly
while driving and hit near-by objects or
luggage in the trun k may be thrown
out, causing an accident.
●Do not allow children to play in the
trunk.
If a child is accidentally locked in the
trunk, they could suffer from heat
exhaustion, suffocation or other inju-
ries.
●Do not allow a child to open or close
the trunk lid.
Doing so may cause the trunk lid to
open unexpectedly, or cause the
child’s hands, head, or neck to be
caught by the closing trunk lid.
■Important points while driving
Never let anyone sit in the trunk. In the
event of sudden braking or a collision,
they are susceptible to death or serious
injury.
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the
body to be caught, resulting in serious
injury.
●Remove any heavy loads, such as snow
and ice, from the trunk lid before
opening it. Failure to do so may cause
the trunk lid to suddenly shut again
after it is opened.
●When opening or closing the trunk lid,
thoroughly check to make sure the
surrounding area is safe.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●Use caution when opening or closing
the trunk lid in windy weather as it may
move abruptly in strong wind.
●The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an
incline than on a level surface, so
beware of the trunk lid unexpectedly
opening or closing by itself. Make sure
that the trunk lid is fully open and
secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure
to press it lightly on its outer surface. If
the trunk handle is used to fully close
the trunk lid, it may result in hands or
arms being caught.
●Do not attach any accessories other
than genuine Lexus parts to the trunk
lid. Such additional weight on the trunk
lid may cause the lid to suddenly shut
again after it is opened.

start
An attempt was made to lock the doors
using the smart access system with
push-button start while the electronic key
was still inside the vehicle. Retrieve the elec-
tronic key from the vehicle and lock the
doors again.
■Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key

with push-button start antennas.
( P.99)
The radio waves may affect the opera-
tion of such devices. If necessary, the
entry function can be disabled. Ask
your Lexus dealer for details, such as
the frequency of radio waves and tim-
ing of the emitted radio waves. Then,
consult your doctor to see if you
should disable the entry function.
●Users of any electrical medical device
other than implantable cardiac pace-
makers, cardiac resynchronization
therapy-pacemakers or implantable
cardioverter defibrillators should con-
sult the manufacturer of the device for
information about its operation under
the influence of radio waves.
Radio waves could have unexpected
effects on the operation of such medi-
cal devices.
