Turn the engine switch off and
ensure that all the doors and
windows are closed.
 Confirm the type of fuel.
■Fuel types
 P.537
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that only
accommodates the special nozzle on
unleaded fuel pumps.
Opening the fuel tank
cap
Perform the following steps to
open the fuel tank cap:
Before refueling the vehicle
WA R N I N G
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure to
do so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to dis-
charge any static electricity. It is important to discharge static elec-
tricity before refueling because
sparks resulting from static electric- ity can cause fuel vapors to ignite
while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to
remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be
heard before fully removing the cap. In hot weather, pressurized
fuel may spray out the filler neck
and cause injury.
●Do not allow anyone that has not
discharged static electricity from their body to come close to an open
fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are
harmful if inhaled.
●Do not smoke while refueling the
vehicle. Doing so may cause the fuel to
ignite and cause a fire.
●Do not return to the vehicle or touch
any person or object that is stati-
cally charged. This may cause static electricity to
build up, resulting in a possible igni-
tion hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into
the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.
●Do not top off the fuel tank.

2624-5. Using the driving support systems
vehicle cannot be detected.
*2: The greater the difference in speed between your vehicle and the detected vehi-
cle is, the farther away the vehicle will be detected, causing the outside rear view
mirror indicator to illuminate or flash.
■The Blind Spot Monitor is opera-
tional when
The Blind Spot Monitor is operational
when all of the following conditions are
met:
●The Blind Spot Monitor is on.
●The shift lever is in a position other
than R.
●The vehicle speed is greater than
approximately 16 km/h (10 mph).
■The Blind Spot Monitor will detect a
vehicle when
The Blind Spot Monitor will detect a
vehicle present in the detection area in
the following situations:
●A vehicle in an adjacent lane over-
takes your vehicle.
●You overtake a vehicle in adjacent
lane slowly.
●Another vehicle enters the detection
area when it changes lanes.
■Conditions under which the system will not detect a vehicle
The Blind Spot Monitor is not designed
to detect the following types of vehicles
and/or objects:
●Small motorcycles, bicycles, pedestri-
ans, etc.*
●Vehicles traveling in the opposite
direction
●Guardrails, walls, signs, parked vehi-
cles and similar stationary objects*
●Following vehicles that are in the
same lane*
●Vehicles traveling 2 lanes away from
your vehicle*
●Vehicles which are being overtaken
rapidly by your vehicle*
*: Depending on the conditions, detec-
tion of a vehicle and/or object may
occur.
■Conditions under which the system may not function correctly
●The Blind Spot Monitor may not detect vehicles correctly in the following situ-
ations:
• When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
• When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding
area on the rear bumper
• When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or
fog • When multiple vehicles are approach-
ing with only a small gap between
each vehicle • When the distance between your vehi-
cle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and
the vehicle that enters the detection
area • When the difference in speed
between your vehicle and another
vehicle is changing • When a vehicle enters a detection
area traveling at about the same
speed as your vehicle • As your vehicle starts from a stop, a
vehicle remains in the detection area
• When driving up and down consecu-
tive steep inclines, such as hills, dips in the road, etc.
• When driving on roads with sharp
bends, consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when
driving on the edge of a lane, and the vehicle in an adjacent lane is far away
from your vehicle
• When towing a trailer

4-5. Using the driving support systems
Driving
• When an accessory (such as a bicycle
carrier) is installed to the rear of the vehicle
• When there is a significant difference
in height between your vehicle and the vehicle that enters the detection
area
• Immediately after the Blind Spot Moni- tor is turned on
●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle
and/or object may increase in the fol-
lowing situations: • When the sensor is misaligned due to
a strong impact to the sensor or its
surrounding area • When the distance between your vehi-
cle and a guardrail, wall, etc. that
enters the detection area is short • When driving up and down consecu-
tive steep inclines, such as hills, dips
in the road, etc. • When vehicle lanes are narrow, or
when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the
detection area
• When driving on roads with sharp bends, consecutive curves, or uneven
surfaces
• When the tires are slipping or spinning • When the distance between your vehi-
cle and a following vehicle is short
• When an accessory (such as a bicycle carrier) is installed to the rear of the
vehicle

When the sensors detect an object,
such as a wall, a graphic is shown
Toyota parking
assist-sensor*
The distance from your vehicle
to objects, such as a wall,
when parallel parking or
maneuvering into a garage is
measured by the sensors and
communicated via the
multi-information display,
head-up display (if equipped)
and a buzzer. Always check the
surrounding area when using
this system.

WA R N I N G
■Pre-driving check
Check that the hood is fully closed
and locked.
If the hood is not locked properly, it
may open while the vehicle is in motion and cause an accident, which
may result in death or serious injury.
■After installing the support rod
into the slot
Make sure the rod supports the hood securely preventing it from falling
down onto your head or body.
NOTICE
■When closing the hood
Be sure to return the support rod to its
clip before closing the hood. Closing
the hood with the support rod not clipped could cause the hood to bend.
Positioning a floor jack
When using a floor jack, follow
the instructions in the manual
provided with the jack and per-
form the operation safely.
When raising your vehicle with
a floor jack, position the jack
correctly. Improper placement

■After a fuse is replaced
●When installing the lid, make sure that
the tab is installed securely.
●If the lights do not turn on even after
the fuse has been replaced, a bulb
may need replacement. ( P.455)
●If the replaced fuse blows again, have
the vehicle inspected by any author- ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer.
■If there is an overload in a circuit
The fuses are designed to blow, protect- ing the wiring harness from damage.
■When replacing light bulbs
Toyota recommends that you use genu-
ine Toyota products designed for this vehicle.
Because certain bulbs are connected to
circuits designed to prevent overload, non-genuine parts or parts not designed
for this vehicle may be unusable.
WA R N I N G
■To prevent system breakdowns
and vehicle fire
Observe the following precautions.
Failure to do so may cause damage
to the vehicle, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than that indi-
cated, or use any other object in
place of a fuse.
●Always use a genuine Toyota fuse
or equivalent. Never replace a fuse with a wire,
even as a temporary fix.
●Do not modify the fuses or fuse
boxes.
