■Before driving
●Check that the floor mat is
securely fixed in the correct
place with all the provided
retaining hooks (c lips). Be espe-
cially careful to perform this
check after cleaning the floor.
●With the engine stopped and
the shift lever in P (continuously
variable transmission) or N
(manual transmission), fully
depress each pedal to the floor

fere with the floor mat.

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 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 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.

which could result in death or seri-
ous injury. Have the vehicle

■Driving in the rain
●Drive carefully when it is raining,
because visibility will be reduced,
the windows may become
fogged-up, and the road will be
slippery.
●Drive carefully when it starts to
rain, because the road surface will
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.

Driving
WARNING
■When driving the vehicle
●Do not drive if you are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay response in an emer-
gency, resulting in an accident.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire if there is any
flammable material nearby.
●During normal driving, do not
turn off the engine. Turning the
engine off while driving will not
cause loss of steering or brak-
ing control, but the power assist
to these systems will be lost.
This will make it more difficult to
steer and brake, so you should
pull over and stop the vehicle as
soon as it is safe to do so.
However, in the event of an
emergency, such as if it
becomes impossible to stop the
vehicle in the normal way:
P.472
●Use engine braking (shift posi-
tion B*1 or downshift*2, 3) to
maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
(
P.153, 155, 160)
*1: Vehicles with a continuously
variable transmission (without
paddle shift switches)
*2: Vehicles with a continuously variable transmission (with
paddle shift switches)
*3: Vehicles with a manual trans-mission
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may resu lt in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.
