Lexus LX 470 1998 Owner's Manual page 230

Brakes and safety chains
D Lexus recommends trailers with brakes that conform to any
applicable federal and state/provincial regulations.
D A safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the chain for
turns. The chain should cross under the trailer tongue to
prevent the tongue from dropping to the ground in case it
becomes damaged or separated. For correct safety chain
procedures, consult your Lexus dealer.
CAUTION
D If the total trailer weight exceeds 453 kg (1000 lb.), trailer
brakes are required.
D Never tap into your vehicle's hydraulic system as it will
lower its braking effectiveness.
D 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 possible
danger of the trailer wandering over into another lane.
Tires
D Ensure that your vehicle's tires are properly inflated. Adjust the
tire pressure to the recommended cold tire pressure indicated
below:
Tire pressure, kPa (kgf/cm 2 or bar, psi)
Front 220 (2.2, 32)
Rear 240 (2.4, 35)
D The trailer tires should be inflated to the pressure recommended
by the trailer manufacturer in respect to the total trailer weight.
Trailer lights
D Trailer lights must comply with federal, state/provincial and local
regulations. The LX470 tow hitch comes with 4−pin wiring. For
towing a recreational vehicle, a 6 or 7−pin connector is required.
See your local recreational vehicle dealer or rental agency for the
correct type of wiring and relays for your trailer. Check for
correct operation of the turn signals and stop lights each time you
hitch up. Direct splicing may damage your vehicle's electrical
system and cause a malfunction of your lights.
Break−in schedule
D Lexus recommends that you do not tow a trailer with a new
vehicle or a vehicle with any new power train component (engine,
transmission, differential, wheel bearing, etc.) for the first 800 km
(500 miles) of driving.
