●
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 dist ributed so that the tongue weight is
9 % to 11 %. (Tongue weight/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 measured 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 we ight and tongue we ight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.Trailer Tongue Weight 1

Driving Trailer hitch assemblies have different weight capacities. Lexus recommends the
use of Lexus hitch/bracket for your vehicle. For details, contact your Lexus
dealer. ●
If you wish to install a trailer hitch, contact your Lexus dealer. ●
Use only a hitch that conforms to the gross 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 hitch whenever you are not towing a trailer. After removing
the hitch, seal any mounting hole in the vehicle body to prevent entry of any
substances into the vehicle.
Remove the clip.
Grasp the lower edge of the hitch
cover and raise the cover. When reattaching the cover, reverse the
steps listed.Hitch

LX570_OM_OM60N01U_(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 contin ue 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 vehicle
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.Connecting and disconnecting a trailer 1

Driving Your vehicle will handle differently when towing a trailer. Help to avoid an acci-
dent, death or serious 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 limit for your trailer as set forth in your trailer owner’s man-
ual, whichever is lowest. Instability of the towing vehicle-trailer combination
(trailer 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 con-
nections. Recheck after driving a short distance. ●
Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become accustomed to the feel of the vehicle-
trailer combination. ●
Reversing with a trailer attached is di fficult and requires practice. Grip the
bottom of the steering wheel and move your hand to the left to move the
trailer to the left. Move your hand to the right to move the trailer to the right.
(This is generally opposite to reversing without a trailer attached.) Avoid sharp
or prolonged turning. Have someone gu ide you when reversing to reduce the
risk of an accident. ●
As stopping distance is increased when towing a trailer, vehicle-to-vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length. ●
Avoid sudden braking as you may skid, re sulting in the trailer jackknifing and
loss of vehicle control. This is especially true on wet or slippery surfaces.Trailer towing tips

198
LX570_OM_OM60N01U_(U) 4-1. Before driving●
Avoid jerky starts or sudden acceleration. ●
Avoid jerky steering and sharp turns, and slow down before making a turn. ●
Note that when making a turn, the traile r wheels will be closer than the vehicle
wheels to the inside of the turn. Comp ensate by making a wider than normal
turning radius. ●
Slow down before making a turn, in crosswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer. ●
Take care when passing other vehicles. Passing requires considerable dis-
tance. 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 efficiency and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 6 or lower.
(  P. 2 1 0 )●
Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending steep or long downhill grades. ●
Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency. ●
Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air cond itioning (if in use), pull your vehicle off the road and
stop in a safe spot. (  P. 5 5 6 )

Driving ●
Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Apply the parking 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 place, release the brakes slowly until the
blocks absorb the load.
Shift into P and apply the parking brake.
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 a forward gear. If reversing, shift into R.
If the parking brake is in manual mode, release the parking brake.
(  P. 2 1 8 )
Release the brake pedal, and slowly pull or back away from the wheel
blocks. Stop and apply the brakes.
Have someone retrieve the blocks. 1

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. 5 6 9 )●
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, an d 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.
