■Matching trailer ball height to trailer
coupler height
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. Coupler

■Before towing
Check that the following conditions are
met:
●Ensure that your vehicle’s tires are prop-
erly inflated. ( P.428)
●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 tongue weight, over-
loading, worn suspension, or other possi-
ble causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all
applicable federal, state/provincial or
local regulations. If they do not, install
rear view mirrors appropriate for towing
purposes.
■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
Trailer towing (vehicles with
towing package)
Your vehicle is de signed primarily
as a passenger-and-load-carrying
vehicle. Towing a trailer can have an
adverse impact on handling, per-
formance, braking, durability, and
fuel consumption. For your safety
and the safety of others, you must
not overload your vehicle or trailer.
You must also ensure that you are
using appropriate towing equip-
ment, that the towing equipment
has been installed correctly and
used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking
performance are affected by trailer
stability, brake performance and
setting, trailer brakes, the hitch and
hitch systems (if equipped).
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with your trailer’s character-
istics and operating conditions.
Lexus warranties do not apply to
damage or malfunction caused by
towing a trailer for commercial pur-
poses.

■GCWR (Gross Combination
Weight Rating)
The maximum allowable gross combi-
nation weight. The gross combination
weight is the sum of the total vehicle
weight (including the occupants, cargo
and any optional equipment installed
on the vehicle) and the weight of the
trailer being towed (including the
cargo in the trailer).
■GVWR (Gross Vehicle Weight
Rating)
The maximum allowable gross vehicle
weight. The gross vehicle weight is the
total weight of the vehicle. When tow-
ing a trailer, it is the sum of the vehicle
weight (including the occupants, cargo
WARNING
●Do not exceed the trailer hitch assem-
bly weight, gross vehicle weight, gross
axle weight and trailer tongue weight
capacities.
●Do not use the dynamic radar cruise
control system when trailer towing.
●Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts while descending steep or long
downhill grades.
●Vehicle-trailer instabil ity is more likely
on steep long downhills. Before
descending steep or long downhill
grades, slow down and downshift. Do
not make sudden downshifts when
descending 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.
●Do not tow a trailer when the compact
spare tire is installed on your vehicle.
■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 applica-
ble federal and state/provincial regula-
tions.
●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 chain 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 wan-
dering 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.
Directly splicing trailer lights may dam-
age your vehicle’s electrical system and
cause a malfunction.

Trailer hitch assemblies have different
weight capacities. Lexus recommends
the use of Lexus hitch/bracket for your
vehicle. For details, contact your Lexus
dealer.

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 hitch ball whenever you
are not towing a trailer. Remove the
trailer hitch if you do not need it.
After removing the hitch, seal any
mounting hole in the vehicle body to
prevent entry of any substances into

WARNING
■Hitch
Trailer hitch assemblies have different
weight capacities established by the hitch
manufacturer. Even though the vehicle
may be physically capable of towing a
higher weight, the operator must deter-
mine the maximum weight rating of the
particular hitch assembly 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.

Driving
Your vehicle will handle differently
when towing a trailer. Help to avoid an
accident, 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 manual, whichever is
lowest. Instability of the towing vehi-
cle-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
connections. 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 tr ailer 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 left. Move
your hand to the right to move the
trailer to right. (This 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
when towing a trailer, vehicle-to
vehicle distance 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, resulting in the trailer jackknif-
ing and a loss of vehicle control. This
is especially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden accel-
eration.
 Avoid jerky steering and sharp
turns, and slow down before making
turn.
 Note that when making a turn, the
trailer wheels will be closer than the
vehicle wheels to the inside of the
turn. Compensate by making a
wider than normal turning radius.
 Slow down before making a turn, in
cross winds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can desta-
bilize the trailer.
 Take care when passing other vehi-
cles. Passing requires considerable
distance. After pass ing 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 effi-
ciency and charging system perfor-
mance when using engine braking,
