WARNING
Do not exceed the trailer hitch assem-
●
bly weight, gross vehicle weight, gross
axle weight and trailer tongue weight
capacities.
Do not use the dynamic radar cruise
●
control system when trailer towing.
Slow down and downshift before
●
descending steep or long downhill
grades. Do not make sudden down-
shifts while descending steep or long
downhill grades.
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 downhill
grades. Avoid holding the brake pedal
down too long or applying the brakes
too frequently. 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
■
Lexus recommends trailers with brakes
that conform to any applicable federal
and state/provincial regulations.
If the gross trailer weight exceeds
●
unbraked TWR, trailer brakes are
required. Lexus recommends trailers
with brakes that conform to all applica-
ble federal and state/provincial regula-
tions.
● Never tap into your 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 trailer and the vehicle. If damage
occurs to the coupling unit or hitch
ball, there is danger of the trailer wan-
dering into another lane.
