Conditions that may trigger the system even if there is no possibility of collision●
When there is an object by the roadside at the entrance to a curve ●
When passing an oncoming vehicle on a curve ●
When driving over a narrow iron bridge ●
When there is a metal object on the road surface ●
When driving on an uneven road surface (nose up, nose down)●
When passing an oncoming vehicle on a left-turn●
When your vehicle rapidly clos es on the vehicle in front●
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel ●
When climbing a steep hill causes an overhead billboard or other metallic
structure to appear directly in the vehicle’s line of travel ●
When an extreme change in vehicle height occurs ●

Off-road precautions Off-road vehicle feature
● Specific design characteristics give it a higher center of gravity than
ordinary passenger cars. This vehicle design feature causes this type of
vehicle to be more likely to rollover. And, utility vehi cles have a signifi-
cantly higher rollov er rate than other types of vehicles.
● An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at th e same speeds as ordinary passen-
ger cars any more than low-slung sports cars a re designed to perform
satisfactorily under off-road cond itions. Therefore, sharp turns at
excessive speeds may cause rollover. This vehicle belongs to the utility ve hicle class, which has higher ground
clearance and narrower tread in relation to the height of its center of grav-
ity to make it capable of performing in a wide variety of off-road applica-
tions.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury. ●
Use tires of the size sp ecified for your vehicle.●
Maintain the recommended level of tire inflation pressure. ●
Do not drive in excess of 75 mph (120 km/h ), regardless of the type of snow tires
being used. ●
Snow tires should be in stalled on all wheels.■
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed limit specified for the tire chains being used or
30 mph (50 km/h), whichever is lower. ●
Avoid driving on bumpy road surfaces or over potholes. ●
Avoid sudden acceleration, abrupt steering, sudden braking and shifting opera-
tions that cause sudden engine braking. ●
Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.■
When installing tire chains
Turn off the vehicle height control.
The vehicle height may change due to the automatic leveling function and you may
catch part of your body in the vehi cle, resulting in an accident. (  P. 320)

LX570_OM_OM60L96U_(U) Trailer Tongue Weight
● A recommended tongue weight varies in accordance with the types of
trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must be
loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongu e weight/Gross trailer weight  100 =
9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitc h when towing, return the front axle
to the same weight as be fore the trailer connection.
If front axle weight cannot be mea sured directly, measure the front
fender height above the front axle before connection. Adjust weight
distributing hitch torque until front fender is return ed to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can
be measured with platform scales found at a highway weighing sta-
tion, building supply company, tru cking company, junk yard, etc.

Matching trailer ball height to trailer coupler height
■
Before towing
Check that the following conditions are met: ●
Ensure that your vehicle’s ti res are properly inflated. (  P. 895)●
Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion. ●
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 tongue weight,
overloading, worn suspensi on, or other possible causes.●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all appl icable federal, state/provincial or local
regulations. If they do no t, install rear view mirrors appropriate for towing pur-
poses. No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer ball
setup must be the proper height for the cou-
pler on the trailer.

After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the sp eed at which trailer swaying occurred is
beyond the limit of your partic ular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increase s as speed increases.
CAUTION■
Trailer towing precautions ●
To tow a trailer safely, use extreme care and drive the vehicle in accordance with
the trailer’s characteristics and operating conditions. Failure to do so could cause
an accident resulting in death or seriou s injury. Vehicle stab ility and braking per-
formance are affected by trailer stability, brake setting and performance, and the
hitch. Your vehicle will handle d ifferently 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 height may change due to the auto-
matic leveling function, and you may catch part of your body in the vehicle, result-
ing in an accident. (  P. 320)
