Driving mode select switch

■
The suspension can be switched for improvement in driveability. (P. 286)

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 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 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.
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 vehi-
cle-trailer increases as speed increases.
