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 weig ht 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 ch ain 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 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 splice trailer lights. Dire ctly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.

■When the four-wheel drive co
ntrol switch can be operated
●The engine switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator
●The indicator blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator continues to blink when you operate the
four-wheel drive control switch to the H4 or L4 position, stop the vehicle completely,
shift the shift lever securely into N and then operate the switch again.
●If the shift lever is moved before the low sp eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted comp letely. The transfer mode disengages both
the front and rear drive shafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the shift lever is in P. You or someone else
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.

Vehicles without Multi-terrain Select:
VSC is automatically turned off. (The VSC OFF indicator will come on.)

VSC and TRAC/Active TRAC are automatically turned off. (The VSC OFF indicator will
come on and the “TRAC OFF” will be sh own on the multi-information display.)
■When the center differential lock/unlock switch can be operated
The engine switch is in IGNITION ON mode.
■The center differential lock indicator
●The indicator blinks while locking/unlocking the center differential.
●If the center differential lock indicator bl inks and the buzzer sounds when the center

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.
