WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine running. This
prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty in oper-
ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay re sponse in an emergency, resulting in an accident.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the engine. Turning the engine off while driving
will not cause loss of steering or braking control, but the power assist to these systems
will be lost. This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 515
●Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. ( P. 217)
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h ) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or no t before driving at such speeds.
●When crossing rivers, turn off height control after putting the vehicle height in high
mode, and drive at 18 mph (30 km/h) or less. Otherwise the vehicle height may
change due to the automatic leveling function, resulting in an accident. ( P. 302)

●A recommended tongue weight varies in accordance with the types of trailers
or towing as described below.
●To ensure the recommended values show
n 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 %. (Tongue weig ht/Gross trailer weight  100 = 9 % to 11 %)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front axle to the
same weight as before the trailer connection.
If front axle weight cannot be meas ured directly, measure the front fender
height above the front axle before co nnection. Adjust weight distributing
hitch torque until front fender is return ed to the same height as before con-
nection.
The gross trailer weight, gross axle weight and tongue weight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

LX570_OM_OM60T33U_(U)4-1. Before driving
Stop your vehicle and a trailer
in line and perform the following:
●Connecting a trailer
Put the 4-Wheel AHC in the “LO” (low) mode.
Turn off the engine switch or the 4-Wheel AHC.
Connect a trailer.
Turn on the engine switch or the 4-Wheel AHC.
Select the N (normal) mode with the height select switch.
When a vehicle loaded with four occupants tows a trailer of about 4000 lb.
(1800 kg) with more than about 400 lb. (180 kg) tongue load, the normal mode
may not be selected. However, there is no problem to continue normal driving.
Drive with sufficient care because of large load.
●Disconnecting a trailer
Put the 4-Wheel AHC in the “LO” (low) mode. (Make sure the vehi\
cle
height is in the “LO” mode by pulling the switch to “ ” on the height select
switch.)
Turn off the engine switch or the 4-Wheel AHC.
Set the supporting leg of a trailer on the ground and raise the hitch by 4 in.
(100 mm).
Turn on the engine switch or the 4-Wheel AHC.
Wait for about 20 seconds until the re ar vehicle height is lowered by the
automatic leveling function.
Make sure the hitch is disconnected. If not, raise the hitch higher and
repeat steps 2 through 5.
Move the vehicle forward in the “LO” mode where the hitch does not touch
anything in the N (normal) mode.
Put the 4-Wheel AHC in the N mode.

■Matching trailer ball height to trailer coupler height
■Before towing
Check that the followin
g conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 569)
●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-
tions. If they do not, install rear view mirrors appropriate for towing purposes.
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 coupler on the
trailer.

WARNING
■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 condit ions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer st ability, brake setting and performanc e, 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 height 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. 302)
■To avoid accident or injury
●Do not exceed the TWR, unbraked 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 trai ler 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 experien ce 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 experience the instability.
●Do not make jerky, abrupt or sharp turns.
●Do not apply the brakes suddenly as you ma y skid, resulting in jackknifing 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 with full-
speed range (if equipped) when trailer towing.
●Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descending 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 steep or long do wnhill 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.

■“HI” (high) height mode
Vehicle height is about 2.0 in. (50 mm) higher at the front, and about 2.4 in.
(60 mm) higher at the rear than the normal mode height.
This mode is suitable when drivin g on bumpy roads or through water.
High height mode is only available when the vehicle speed is under 18 mph
(30 km/h).
■N (normal) height mode
The standard vehicle height. This mode is suitable for ordinary driving.
When driving at high speeds, the vehicle height is automatically lowered by
0.8 in. (20 mm) in the front and 0.6 in. (15 mm) in the rear, to ensure excellent
aerodynamic character istics and stability.
If the vehicle speed drops, normal he ight mode is automatically resumed.
■“LO” (low) height mode
Vehicle height is about 2.4 in. (60 mm) lower at the front, and about 1.6 in. (40
mm) lower at the rear than the normal mode height.
This mode allows easy access to the vehicle.
Low height mode is only available wh en the vehicle is travelling at 7 mph
(12 km/h) or less. When the vehicle speed exceeds 7 mph (12 km/h), normal
height mode is automatically selected.
