When driving
lCrosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If swaying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehicle and trailer will stabilize.
lTake 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.
lIn order to maintain engine braking efficiency when driving on a long
steep downgrade, do not use overdrive. Transmission shift range posi-
tion must be in 4 in S mode.
lDue to the added load of the trailer, your vehicle's engine may over-
heat 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. 587)
lAlways place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.

lWhen restarting after parking on a slope:
With the transmission in the P position, start the engine. Be sure
to keep the brake pedal depressed.
Shift into 3, 2, 1, or the R position (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
nBefore towing
Check that the following conditions are met:
lThe vehicle's tires are properly inflated. (→P. 4 8 7 )
lTrailer tires are inflated according to the trailer manufacturer's recommendation.
lAll trailer lights work.
lAll lights work each time you connect them.
lThe trailer ball is set up at the proper height for the coupler on the trailer.
lThe vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
lThe trailer cargo is securely loaded.
lThe 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.
nBreak-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential and wheel bearing), Lexus recommends that
you do not tow a trailer until it has been driven for over 500 miles (800 km).
However, avoid full throttle acceleration.
nMaintenance
lIf you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner's Manual Sup-
plement” or “Scheduled Maintenance”.)
lRetighten the fixing bolts of the towing ball and bracket after approximately 600
miles (1000 km) of trailer towing.
