2023 TOYOTA RAV4 HYBRID ECU

2084-1. 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 vehi-
cle weight (including the occu-
pants, cargo and any optional
equipment installed on the vehi-
cle) and the tongue weight.
WARNING
●Vehicle-trailer instability is more
likely on steep long downhills.
Before descending steep or
long downhill grades, slow
down and downshift. Do not
make sudden downshifts when
descending steep or long down-
hill grades. Avoid holding the
brake pedal down too long or
applying the brakes too fre-
quently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
●Do not tow a trailer when the
compact spare tire is installed
on your vehicle.
■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.
