2023 TOYOTA HIGHLANDER HYBRID ECU

1984-1. Before driving
■GCWR (Gross Combination
Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
■GVWR (Gross Vehicle
Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehi-
cle weight is the total weight of
the vehicle. When towing a
trailer, it is the sum of the vehicle
weight (including the occu-
pants, cargo and any optional
equipment installed on the vehi-
cle) and the tongue weight.
■GAWR (Gross Axle Weight
Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).
WARNING
■When towing a trailer
Toyota recommends trailers with
brakes that confor m to any appli-
cable federal and state/provincial
regulations.
●If the gross trailer weight
exceeds unbraked TWR, trailer
brakes are required. Toyota rec-
ommends trailers with brakes
that conform to all applicable
federal and state/provincial reg-
ulations.
●Never tap into y our vehicle’s
hydraulic system, as this will
lower the vehicle’s braking
effectiveness.
●Never tow a trailer without using
a safety chain securely attached
to both the traile r and the vehi-
cle. If damage occurs to the
coupling unit or hitch ball, there
is danger of the trailer wander-
ing into another lane.

bility at intersections and on
curves by automatically adjust-
ing the direction of the light axis
of the headlights according to
vehicle speed and the degree of the tire’s angle as controlled by
steering input.
AFS operates at speeds of 6 mph
(10 km/h) or higher.
■Customization

dows, and turn the power
switch off.
 Confirm the type of fuel.
■Fuel types
 P. 4 9 8
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unle aded fuel pumps.
Opening the fuel tank
cap
The fuel tank of your vehicle
has a special structure,
which requires a reduction
in fuel tank pressure before
refueling. After the opener
switch has been pressed, it
will take several seconds
until the vehicle is ready for
refueling.
Before refueling the vehi-
cle
WARNING
■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 sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity 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 f uel tank cap is
loosened. Wait until the sound
cannot be heard before fully
removing the cap. In hot
weather, pressurized fuel may
spray out of 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 statically charged.
This may cause static electricity
to build up, resulting in a possi-
ble ignition 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.

2824-5. Using the driving support systems
from your vehicle*
●Vehicles which are being over-
taken rapidly by your vehicle*
*
: Depending on the conditions, detection of a vehicle and/or
object may occur.
■Conditions under which the
system may not function cor-
rectly
●In the following situations, vehi-
cles may not be detected correctly
(while driving):
• When the sensor is misaligned
due to a strong impact to the sen-
sor or its surrounding area
• When mud, snow, ice, a sticker,
etc. is covering the sensor or sur-
rounding 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 approaching with only a small gap
between each vehicle
• When the distanc e between your
vehicle and a following vehicle is
short
• When there is a significant differ- ence in speed between your vehi-
cle 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 con- secutive 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 adja-
cent lane is far away from your vehicle
• When an accessory (such as a bicycle carrier) is installed to the
rear of the vehicle
• When there is a significant differ- ence in height between your vehi-
cle and the vehicle that enters the
detection area
• Immediately after the Blind Spot
Monitor is turned on
• When towing with the vehicle●Instances of unnecessary detec-
tion may increase in situations
such as the following (while driv-
ing):
• When the sensor is misaligned due to a strong impact to the sen-
sor or its surrounding area
• When the distance between your vehicle and a guardrail, wall, etc.
that enters the detection area is
short
• When driving up and down con-
secutive 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 r oads with sharp
bends, consecutive curves, or
uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is
short
• When an accessory (such as a bicycle carrier) is installed to the
