For safety and security
Exhaust gas precau-
tions
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 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 back door closed.
●If you smell exhaust gases in
the vehicle even when the back
door is closed, open the win-
dows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
engine.
●Do not leave the vehicle with
the engine on 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 snow-
banks build up around the vehi-
cle 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 corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

Before driving
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
given.
●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 fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 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 bat- tery-saving mode to disable the
smart key system. ( P.109)
●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 vehi-
cle. 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.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked before pulling the
door handle again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
■When the vehicle is not driven
for extended periods
●To prevent theft of the vehicle, do
not leave the electronic key within
6 ft. (2 m) of the vehicle.
●The smart key system can be deactivated in advance. (
P.535)
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.109)
■To operate the system properly
Make sure to carry the electronic
key when operating the system. Do
not get the electronic key too close
to the vehicle when operating the
system from the outside of the vehi-
cle.

ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention function may not operate.)

be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■Engine speed while driving
(vehicles with a continuously
variable transmission)
In the following conditions, the
engine speed may become high
while driving. This is due to auto-
matic up-shifting control or
down-shifting implementation to
meet driving conditions. It does not
indicate sudden acceleration.
