No matter which class of tow hitch applies,

Trailer towing (vehicles with-
out towing package)

Lexus does not recommend towing
a trailer with your vehicle. Lexus
also does not recommend the
installation of a tow hitch or the use
of a tow hitch carrier for a wheel-
chair, scooter, bicycle, etc. Your
vehicle is not designed for trailer
towing or for the use of tow hitch
mounted carriers.

Trailer towing (vehicles with
towing package)

Your vehicle is designed 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.

Contact your Lexus dealer for fur-
ther information about additional
requirements such as a towing kit,
etc.

4-1. Before driving

for a more safe trailer hookup, the trailer

ball setup must be the proper height for the

coupler on the trailer.

Before towing

Check that the following conditions are

met:

●

Ensure that your vehicle’s tires are prop-

erly inflated. (



P.458)

●

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.

■

Adaptive Variable Suspension System

(if equipped)

The suspension can be switched for

improvement in driveability. (



P.279)

■

Break-in schedule

If your vehicle is new or equipped with any

new power train components (such as an

engine, hybrid transmission, rear 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

require more frequent maintenance due

to the additional load. (See “Warranty

Supplement” or “Scheduled Mainte-

nance”.)

●

Retighten the fixing bolts of the towing

ball 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 swaying by

turning the steering wheel.

• Begin releasing the accelerator pedal

immediately 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. (if enabled, Trailer Sway

Control can also help to stabilize the vehicle

and trailer.)

●

After the trailer swaying 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 appropri-

ate, 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 pre-

vent instability. Remember that swaying of

the towing vehicle-trailer increases as

speed increases.

WARNING

■

Trailer towing precautions

To tow a trailer safely, use extreme care

and drive the vehicle in accordance with

the trailer’s characteristics and operating

conditions. Failure to do so could cause

an accident resulting in death or serious

injury. Vehicle stability and braking per-

formance are affected by trailer stability,

brake setting and performance, and the

hitch. Your vehicle will handle differently

when towing a trailer.

■

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

sufficient capacity is required.

●

Adjust the tongue weight within the

appropriate 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, which-

ever is lowest. Slow down sufficiently

before making a turn, in cross winds,

on wet or slippery surface, etc. to help

avoid an accident. If you experience a

vehicle-trailer instability from reduc-

ing 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 may skid, resulting in jackknifing

and loss of vehicle control. This is

especially true on wet or slippery sur-

faces.

●

Do not exceed the trailer hitch assem-

bly weight, gross vehicle weight, gross

axle weight and trailer tongue weight

capacities.

●

Do not use the following systems when

trailer towing.

• Dynamic radar cruise control with

full-speed range

• LTA (Lane Tracing Assist)

• PCS (Pre-Collision System)

• BSM (Blind Spot Monitor) (if

equipped)

●

Slow down and downshift before

descending steep or long downhill

grades. Do not make sudden down-

shifts while descending steep or long

downhill grades.

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
and any optional equipment installed
on the vehicle) and the tongue weight.

WARNING

●

Vehicle-trailer instability 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.

■

TWR (Trailer Weight Rating)

The maximum allowable gross trailer
weight. The gross trailer weight is the
sum of the trailer weight and the weight
of the cargo in the trailer.
TWR is calculated assuming base vehi-
cle with one driver, one front passen-
ger, towing package (if available), hitch
and hitch systems (if required).

Additional optional equipment, passengers
and cargo in the vehicle will reduce the
trailer weight rating so as not to exceed
GCWR, GVWR and GAWR.
If the gross trailer weight exceeds 3000
lb. (1360 kg), it is recommended to use a
trailer with 2 or more axles.

WARNING

■

Hitches

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.

Auto current cut-off function

In case of over current, the auto cut-off

function stops the power flowing to the

trailer lights to prevent damage to the vehi-

cle’s electrical system.
This function is activated when the rated

current of any of the following trailer light

circuit components is exceeded:

●

Tail lights: maximum 7.8 A

●

Stop/turn signal light (right): maximum

4.5 A

●

Stop/turn signal light (left): maximum 4.5

■

When the auto current cut function is

activated

If a trailer light does not come on due to the

activation of the auto current cut function,

the light system will need to be reset.
Follow the reset procedure shown below.

●

If a tail light does not come on, turn off the

headlight switch.

●

If the right-side stop/turn signal light does

not come on, put the turn signal in the off

position or remove foot from the brake

pedal.

●

If the left-side stop/turn signal light does

not come on, put the turn signal in the off

position or remove foot from the brake

pedal.

If the emergency flashers do not operate,

press the emergency flasher switch to turn

them off.
After the light system is reset, operate the

light switches again to see if the lights oper-

ate normally.
If the lights do not operate normally, have

the vehicle inspected by your Lexus dealer.

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 vehi-

Driving

cle-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 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
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 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 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 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 effi-
ciency and charging system perfor-
mance when using engine braking,
do not put the transmission in D.
(



P.189)



Instability happens more frequently
when descending steep or long
downhill grades. Before descend-
ing, 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

180

4-1. Before driving

frequently. This could cause the
brakes to overheat and result in
reduced braking efficiency.



Due to the added load of the trailer,
your 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 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.446)



Always place wheel blocks under
both the vehicle’s and the trailer’s
wheels when parking. Put the trans-
mission in P and apply the parking
brake. Avoid parking on a slope, but
if unavoidable, do so only after per-
forming 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 hybrid system.



When restarting after parking on a
slope:

With the transmission in P, start the
hybrid system. Be sure to keep the
brake pedal depressed.

Shift into a forward gear. If revers-
ing, shift into R.

If the parking brake is in manual
mode, release the parking brake.
(
