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

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differential or wheel bearing), Lexus recommends that you do not
tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will requir e more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.) ●
Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing. ■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal i mmediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. ●
After the trailer sw aying 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 speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.

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 ma y 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.
