●Ensure that your vehicle’s tires are properly inflated. (→ P. 578)
●Trailer tires are inflated according to the trailer manufacturer’s recommendation.
●All trailer lights work as required by law.
●All lights work each time you connect 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 to ngue weight, overload-
ing, worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local regula-

CAUTION
■Hitch
Trailer hitch assemblies have different weight capacities established by the hitch manu-
facturer. Even though the vehicle may be physically capable of towing a higher weight,
the operator must determine the maximum weight rating of the particular hitch assem-
bly and never exceed the maximum weight rating specified for the trailer-hitch.
Exceeding the maximum weight rating set by the trailer-hitch manufacturer can cause
an accident resulting in death or serious personal injuries.
■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 applicable federal and state/pro-
vincial regulations.
●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 co upling unit or hitch ball, there is danger of
the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage.
■Do not directly splice trailer lights
Do not directly splic e trailer lights. Directly splicin g trailer lights may damage your
vehicle’s electrical system and cause a malfunction.

could be seriously injured. You must comple te the shifting of the transfer mode and
confirm that the indicator has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.
