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.

● If you wish to install a trailer hitch, contact your Lexus dealer.
● Use only a hitch that conforms to the gros s trailer weight requirement
of your vehicle.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coating of grease.
● Remove the trailer hitc h whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to pre-
vent entry of any substances into the vehicle.

LX570_OM_OM60L96U_(U) Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to
avoid an accident, death or seriou s injury, keep the following in mind
when towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Lexus recommends that the vehicle- trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road. Do not exceed this limit, the posted
towing speed limit or the speed limi t for your trailer as set forth in your
trailer owner’s manual, whichever is lowest. Inst ability of the towing
vehicle-trailer combination (tra iler sway) increases as speed
increases. Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and rever sing with the trailer attached in an
area away from traffic until you beco me accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the le ft. Move your hand to the right to move the
trailer to the right. (T his is generally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to reduce the risk of an accident.
● As stopping distance is increased wh en towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.

3942-5. Driving information
LX570_OM_OM60L96U_(U) ● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turn s, and slow down before making a
turn.
● Note that when making a turn, the trailer wheels will be closer than the
vehicle wheels to the inside of th e turn. Compensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficie ncy and charging system perfor-
mance when using engine braking, do not put the transmission in “D”.
If in the S mode, the transmission shift range position must be in 5 or
lower.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending , slow down and downshift. Do not
make sudden downshifts while desc ending steep 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.
● Due to the added load of the trail er, your vehicle’ s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving up
a long or steep grade. If the engine coolant temperature gauge indi-
cates overheating, immediately turn off the air conditioning (if in use),
pull your vehicle off the road and stop in a safe spot. (  P. 878)

When driving
LX570_OM_OM60L96U_(U) ● Always place wheel blocks under bo th the vehicle’s and the trailer’s
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in “P”. Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into “P” and turn off the engine.
● When restarting after parking on a slope:
With the transmission in “P”, start the engine. Be sure to keep the
brake pedal pressed.
Shift into “D” or “R” (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks. STEP 1
