2023 TOYOTA HIGHLANDER HYBRID differential

1964-1. Before 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, hybrid
transmission, rear differential or
wheel bearing), 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.
