Matching trailer ball height to trailer coupler height
■
Before towing
Check that the following conditions are met: ●
Ensure that your vehicle’s tires are properly inflated. (  P. 8 8 9 )●
Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion. ●
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,
overloading, 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 pur-
poses. 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 cou-

When driving

AVS (adaptive variable suspension system)
The suspension can be switched for improvement in driveability. (  P. 3 2 9 )■
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 tow-
ing. 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 traile r, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Owner’s Guide”, “Warranty and Services Guide”,
“Owner’s Manual Supplement” or “Warranty Booklet”.) ●
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 peda l 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.)
