Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WA R N I N G
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless.
Observe the following precautions.
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 vehicle even when the trunk lid is closed, open the
windows and have the vehicle 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 wh ile the engine is running, exhaust gases
may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked period ically. 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.

■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on when
you start the engine, this could mean that these systems are not available to help pro-
tect you in an accident, which could result in death or serious injury. Have the vehicle
inspected by your Lexus dealer immediately if this occurs.

●The engine is not running.
●The shift lever is in any position other than D.
●Neither normal mode nor Eco drive mode is selected. ( →P. 2 4 8 )

suspended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION ON mode. It may also take a few minutes to display the tire infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge. Eco Driving Indicator Light

ing), the Eco Driving Indicator Light will turn
on. When the acceleration exceeds the Zone
of Eco driving, or when the vehicle is stopped,

WA R N I N G
■Trunk easy closer (vehicles with
power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or any-
thing 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 whil e the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take ex tra care when on an incline, as the trunk
lid may open or close suddenly.
●On an incline, the trunk lid may suddenly 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 opener and closer may detect an abnor-
mality and automatic operation may be stoppe d. In this case, the trunk lid has to be
operated manually. Take extra care in this situation, as the stopped trunk lid may sud-
denly shut, causing an accident.
• When the trunk lid contacts an obstacle
• 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 opera-
tion
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or the
trunk lid may suddenly shut again after it is opened.
■Jam protection function (vehicles with power trunk opener and closer)
Observe the following precautions.
Failure to do so may cause serious injury.
●Never use any part of your body to intent ionally activate the jam protection function.
●The jam protection function may not work if something gets caught just before the
trunk lid fully closes. Be careful not to catch fingers or anything else in the trunk lid.
●The jam protection function may not work depending on the shape of the object that
is caught. Be careful not to catch fingers or anything else.
In the event that the trunk lid is left slightly open,
the trunk easy closer will automatically close it
to the fully closed position. It takes several sec-
onds before the trunk easy closer begins to
operate. Be careful not to catch fingers or any-
thing else in the trunk lid, as this may cause
bone fractures or other serious injuries.

Operation of each component
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the system
may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor, or in the door pockets or glove box when the engine is started or engine switch modes are
changed.
●Do not leave the electronic key on top of the instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outside the cabin and the doors will become lockable from the
outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within th e effective range, the doors may be locked or
unlocked by anyone. However, only the doors detecting the electronic key can be used
to unlock the vehicle.
●Even if the electronic key is not inside the vehicle, it may be possible to start the engine
if the electronic key is near the window.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash when th e electronic key is within the effective range.
(The doors will automatically be locked after approximately 60 seconds if the doors
are not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic key is near
the vehicle, there is a possibility that the door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (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. 110)
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the multi-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden approach to the effective range or door handle may prevent the doors from
being unlocked. In this case, return the door handle to the original position and check
that the doors unlock before pulling the door handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
●If there is another electronic key in the de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.
