ECU TOYOTA HIGHLANDER 2022 Workshop Manual

1884-1. Before driving
WARNING
●Even if the total load of occu-
pant’s weight and the cargo
load is less than the total load
capacity, do not apply the load
unevenly. Improper loading may
cause deteriorat ion of steering
or braking control which may
cause death or serious injury.
■When using a roof luggage
carrier (vehicles with roof
rails)
Observe the following precau-
tions:
●Place the cargo so that its
weight is distributed evenly
between the front and rear
axles.
●If loading long or wide cargo,
never exceed the vehicle overall
length or width. (
P.500)
●Before driving, make sure the
cargo is securel y fastened on
the roof luggage carrier.
●Loading cargo on the roof lug-
gage carrier will make the cen-
ter of gravity of the vehicle
higher. Avoid high speeds, sud-
den starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control or vehicle rollover due to
failure to operate this vehicle
correctly and resu lt in death or
serious injury.
●If driving for a long distance, on
rough roads, or at high speeds,
stop the vehicle now and then
during the trip to make sure the
cargo remains in its place.
●Do not exceed 165 lb. (75 kg)
cargo weight on the roof lug-
gage carrier.
NOTICE
■When loading cargo
Be careful not to scratch the sur-
face of the moon roof or pan-
oramic moon roof.

Driving
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched.
Do not drive if the trailer is not
level, and check for improper
tongue weight, overloading, worn
suspension, or other possible
causes.
●The trailer cargo is securely
loaded.
●The rear view mirrors conform to
all applicable federal, state/provin-
cial or local regu lations. If they do
not, install rear view mirrors
appropriate for towing purposes.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transaxle,
transfer [AWD models], rear differ-
ential [AWD models] or wheel bear-
ing), Toyota recommends that you
do not tow a trailer until the vehicle
has been driven for over 500 miles
(800 km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 50 mph
(80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle
will require more f requent mainte-
nance due to the additional load.
(See “Scheduled Maintenance
Guide” or “Owner’s Manual Sup-
plement”.)
●Retighten the fixing bolts of the
towing ball and bracket after
approximately 600 miles (1000
km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to contr ol trailer sway-
ing by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradu-
ally to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and trailer should stabilize.
(if enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.)
●After the trailer swaying has
stopped:
• Stop in a safe place. Get all occu- pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not
shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle-trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that
swaying of the towing vehicle-trailer
increases as speed increases.

■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.

1With the headlights on, push
the lever away from you to
turn on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
2Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams with
the headlights on or off.
AFS (Adaptive Front-lighting
System) secures excellent visi-
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
Some functions can be customized.

To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unle aded fuel pumps.
■If the malfunction indicator

The malfunction indicator lamp may
illuminate erroneous ly if refueling is
performed repeatedly when the fuel
tank is nearly full.

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.

WARNING
■Luggage cover
●When installing/stowing the lug-
gage cover, make sure that the
luggage cover is securely
installed/stowed. Failure to do
so may result in serious injury in
the event of sudden braking or a

sudden braking or turning, the
item may go flying and strike an
occupant. This could lead to an
unexpected accident, resulting
in death or serious injury.
●Do not allow ch ildren to climb
