Trailer towing (vehicles with towing package)
Trailer towing
Your vehicle is designed primarily as a passenger-and-load-carrying vehicle. Tow-
ing a trailer can have an adverse impact on handling, performance, 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 appro-
priate towing equipment, 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 perform-
ance and setting, trailer brakes, the hitch and hitch systems (if equipped).To tow
a trailer safely, use extreme care and drive the vehicle in accordance with your
trailer's characteristics and operating conditions.Lexus warranties do not apply to
damage or malfunction caused by towing a trailer for commercial purposes.
Contact your Lexus dealer for further information about additional requirements
such as a towing kit, etc.
INFORMATION
■
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.

●
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, 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
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.
■
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 require more frequent maintenance due to the
additional load. (See "Warranty and Services Guide", "Owner’s Manual Supplement"
or "Scheduled Maintenance".)
●
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 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 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 performance 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.
●
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, whichever 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 reducing
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 surfaces.
●
Do not exceed the trailer hitch assembly 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

WARNING
•
LTA (Lane Tracing Assist)
•
LDA (Lane Departure Alert)
•
PCS (Pre-Collision System)
•
BSM (Blind Spot Monitor)
●
Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descending steep or long downhill grades.
●
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.
●
Vehicles with compact spare tire: Do not tow a trailer when the compact spare tire is
installed on your vehicle.
●
Vehicles with an emergency tire puncture repair kit: Do not tow the vehicle when the
tire installed is repaired with the emergency tire puncture repair kit.
■
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/
provincial 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 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 wandering into another lane.

●
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 the vehicle.
WARNING
Trailer hitch assemblies have different weight capacities established by the hitch manufac-
turer. Even though the vehicle may be physically capable of towing a higher weight, the
operator must determine 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.
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.
Positions for towing hitch receiver and hitch ball
A
Weight carrying ball position: 43.0 in.
(1093.0 mm)
B
Hitch receiver pin hole position: 34.6 in.
(880.0 mm)
Connecting trailer lights
Please consult your dealer when installing trailer lights, as incorrect installation may
cause damage to the vehicle's lights. Please take care to comply with your state's
laws when installing trailer lights.
NOTICE
Do not directly splice trailer lights. Directly splicing trailer lights may damage your
vehicle's electrical system and cause a malfunction.
Trailer towing tips
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.
1-4. Entering/exiting the vehicle and loading luggage

e driving
●
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 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 connec-
tions. 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 jackknifing and a
loss of vehicle control. This is especially true on wet or slippery surfaces.
●
Avoid jerky starts or sudden acceleration.
●
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 surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
●
Take care when passing other vehicles. 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 efficiency and charging system performance when
using engine braking, do not put the transmission in D. If in the M mode, the
transmission shift range position must be in 6 or lower.
1-4. Entering/exiting the vehicle and loading luggage
112
●
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, 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 indicates overheating,
immediately turn off the air conditioning (if in use), pull your vehicle off the road
and stop in a safe spot.
Parking on a slope when towing a trailer
Always place wheel blocks under both the vehicle's and the trailer's wheels when
parking. Put the transmission in P and apply the parking brake. Avoid parking on a
slope, but if unavoidable, do so only after performing the following:
1
Apply the brakes and keep them applied.
2
Have someone place wheel blocks under both the vehicle's and trailer's
wheels.
3
When the wheel blocks are in place, release the brakes slowly until the blocks
absorb the load.
4
Shift into P and apply the parking brake.
5
Turn off the engine.
Starting off on a slope when towing a trailer
1
With the transmission in the P, start the engine.
2
Be sure to keep the brake pedal depressed.
3
Shift into a forward gear.
If reversing, shift into R.
4
If the parking brake is in manual mode, release the parking brake.
5
Release the brake pedal, and slowly pull or back away from the wheel blocks.
Stop and apply the brakes.
6
Have someone retrieve the blocks.
