■Trailer towing precautions
●To tow a trailer safely, use extreme care an
d drive the vehicle in accordance with the
trailer’s characteristics and operating conditions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer stability, brake setting an d performance, and the hitch. Your vehicle
will handle differently when towing a trailer.
●Set the vehicle height to the “LO” mode and turn off the 4-Wheel AHC when you
connect a trailer, otherwise the vehicle heig ht may change due to the automatic level-
ing function, and you may catch part of your body in the vehicle, resulting in an acci-
dent. ( P. 2 9 7 )
■To avoid accident or injury
●Do not exceed the TWR, unbrak ed TWR, GCWR, GVWR or GAWR.
●If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with suffi-
cient capacity is required.
●If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing hitch with
sufficient capacity is required.
●Adjust the tongue weight within the approp riate range. Place heavier loads as close
to the trailer axle as possible.
●Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed limit
for your trailer as set forth in your trailer owner’s manual, whichever is lowest. Slow
down sufficiently before making a turn, in crosswinds, on wet or slippery surface, etc.
to help avoid an accident. If you experience a vehicle-trailer instability from reducing
a certain speed, slow down and make sure you keep your vehicle speed under the
speed of which you expe rience the instability.
●Do not make jerky, abrupt or sharp turns.
●Do not apply the brakes suddenly as you may skid, resulting in ja ckknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces.
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities.
●Do not use cruise control (if equipped) or dynamic radar cruise control (if equipped)
when trailer towing.
●Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descen ding steep or long downhill grades.
●Vehicle-trailer instability is more likely on steep long down hills. Before descending
steep or long downhill grades, slow down and downshift. Do not make sudden down-
shifts when descending stee p 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.

■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 to disable the pre-collision system
In the following situations, disable the system, as it may not operate properly, possibly
leading to an accident resultin g in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another vehicle
●When transporting the vehicle via truck, boat, train or similar means of transportation
●When the vehicle is raised on a lift with the engine running and the tires are allowed to
rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or
speedometer tester, or when using an on vehicle wheel balancer
●When a strong impact is applied to the front bumper or front grille, due to an accident
or other reasons
●If the vehicle cannot be driven in a stable manner, such as when the vehicle has been
in an accident or is malfunctioning
●When the vehicle is driven in a sporty manner or off-road
●When the tires are not properly inflated
●When the tires are very worn
●When tires of a size other than specified are installed
●When tire chains are installed
●If the suspension is modified
●If the front of the vehicle is raised or lowered, such as when loaded with heavy lug-
gage

■Situations unsuitable for dynamic radar cruise control with full-speed range
Do not use dynamic radar cruise control wi th full-speed range in any of the following
situations.
Doing so may result in inappropriate speed control and could cause an accident result-
ing in death or serious injury.
●Roads where there are pedestrians, cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep downhills, or where there are sudden changes between sharp up and down
gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad enough that they may prevent the sensors from
detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the front surface of the radar sensor or camera sen-
sor
●In traffic conditions that require frequent repeated acceleration and deceleration
●When your vehicle is towing a trailer or during emergency towing
●When an approach warning buzzer is heard often

■Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following situations:
●Actual vehicle speed falls more than approximately 10 mph (16 km/h) below the preset
vehicle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below approximately 25 mph (40 km/h).
●VSC is activated.
●The switching operation continues for 5 seco nds or more after the center differential
lock switch has been operated.
■If “Cruise Control Malfunction Visit Your Dealer” is shown on the multi-information
display
Press the “ON/OFF” button once to deactivate the system, and then press the button
again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately after
being activated, there may be a malfunction in the cruise control system. Have the vehi-
cle inspected by your Lexus dealer.

Doing so may result in loss of control and could cause an accident resulting in death or
serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep hills
Vehicle speed may exceed the set speed when driving down a steep hill.

NOTICE
■When parking in areas with limited overhead height
After leaving the vehicle or unloading the luggage, the vehicle height may be slightly
higher than normal. Take care wh
en overhead height is limited.
■To avoid damage to the vehicle
●Normal mode will be switched to automatically even if the vehicle is started off in low
mode. Take care when over head height is limited.
●Do not select the low mode when driving on bumpy roads, as the underbody of the
vehicle may contact the road surface.
●When traveling on bumpy roads or through water, or when towing, turn off easy
access mode.
■Avoid rapid changes to the vehicle height
As the pump may overheat. Leave at a few seconds between selections when changing
the vehicle height mode.
