WARNING
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an acc ident, resulting in
death or serious injury.
■ When installing the driver’s floor mat
● Do not use floor mats designed for other models or different mo del year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
● Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the engine stopped and the shift
lever in P (continuously variable trans-
mission) or N (manual transmission),
fully depress each pedal to the floor to
make sure it does not interfere with the
floor mat.

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 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 l id is closed,
open the windows and have the vehicle inspected at your Toyota 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 on for a long time.
If such a situation cannot be avoided, park the vehicle in an o pen 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 exhaus t noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

*1: These lights turn on when the engine switch is turned to the “ON” position
(vehicles without a smart key system) or the engine switch is turned to
IGNITION ON mode (vehicles with a smart key system), to indicat e that a
system check is being performed. They will turn off after the engine is
started, or after a few seconds. There may be a malfunction in a system if
a light does not come on, or turn off. Have the vehicle inspect ed by your
Toyota dealer.

WARNING
■The display at low temperatures
Allow the interior of the vehicle to warm up before using the d isplay. At
extremely low temperatures, the display monitor may respond slo wly, and
display changes may be delayed.
For example, there is a lag between the driver’s shifting and t he new gear
number appearing on the display. This lag could cause the drive r to down-
shift again, causing rapid and excessive engine braking and pos sibly an
accident resulting in death or injury.
■ Cautions during setting up the display
As the engine needs to be running during setting up the display , ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxi de (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
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
are in the red zone. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 531)
