421-1. For safe use
Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
■When parking
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time.
If such a situation cannot be avoided,
park the vehicle in an open space and
ensure that exhaust fumes do not enter
the vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.
■Exhaust pipe
The exhaust system needs to be checked
periodically. If there is a hole or crack
caused by corrosion, damage to a joint
or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired
by your Lexus dealer.

less remote control or mechanical
key.
 For Canada: Unlock the doors using

remote control.
 Turn the engine switch to ACCES-
SORY or IGNITION ON mode, or
start the engine. (The alarm will be
deactivated or stopped after a few
seconds.)
■System maintenance

alarm system.
Alarm

give an alert when an intrusion is
detected.
The alarm is triggered in the follow-
ing situations when the alarm is set:
 A locked door is unlocked or
opened in any way other than
using the entry function, wireless
remote control or mechanical
key

■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 be displayed when a warn-
ing 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.
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 num-
ber appearing on the display. This lag
could cause the driver to downshift
again, causing rapid and excessive
engine braking 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.393)

WARNING
●Vehicles without power trunk lid:
When closing the trunk lid, make sure
to press it lightly on its outer surface. If
the trunk grip 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.
■Trunk easy closer (vehicles with
power trunk lid)
In the event that the trun k lid is left slightly
open, the trunk easy closer will automati-
cally close it to the fully closed position. It
takes several seconds before the trunk
easy closer begins to operate. Be careful
not to catch fingers or anything else in
the trunk lid, as this may cause bone frac-
tures or other serious injuries.
■Power trunk lid (if equipped)
Observe the following precautions when
operating the power trunk lid.
Failure to do so may cause serious injury.
●Check the safety of the surrounding
area to make sure there are no obsta-
cles or anything that could cause any
of your belongings to get caught.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●If the trunk closer switch is pressed
while the trunk lid is opening during
automatic operation, the trunk lid
stops opening. Take extra care when
on an incline, as the trunk lid may open
or close suddenly.
●On an incline, the trunk lid may sud-
denly shut after it opens automatically.
Make sure the trunk lid is fully open
and secure before using the trunk.
●In the following situations, the power
trunk lid may detect an abnormality
and automatic operation may be
stopped. In this case, the trunk lid has
to be operated manually. Take extra
care in this situat ion, as the stopped
trunk lid may suddenly shut, causing an
accident.
• When the trunk lid contacts an obsta- cle
• When the battery voltage suddenly drops, such as when the engine switch
is turned to IGNITION ON mode or
the engine is started during automatic
operation
●Do not attach any accessories other
than genuine Lexus parts to the trunk
lid. The power trunk lid may not oper-
ate, causing itself to malfunction, or the
trunk lid may suddenly shut again after
it is opened.
■Hands Free Power Trunk Lid (vehi-
cles with power trunk lid)
Observe the following precautions.
Failure to do so may cause serious injury.
●Exhaust gases cause the exhaust pipes
to become quite hot. When operating
the Hands Free Power Trunk Lid, be
careful not to touch the exhaust pipe.
●Do not operate the Hands Free Power
Trunk Lid if there is little space under
the rear bumper.
■Jam protection function (vehicles
with power trunk lid)
Observe the following precautions.
Failure to do so may cause serious injury.
