2-5. Driving information
GX460_U.S.A. (OM60J00U)●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
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 crosswinds, on wet or slippery sur-
faces, 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 perfor-
mance when using engine braking, do not put the transmission in D.
Transmission shift range position must be in 5 in the S mode.
● 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 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 indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. ( →P. 744)

When driving
GX460_U.S.A. (OM60J00U)●
Always place wheel blocks under both the vehicle’s and the trailer’s
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’s and
trailer’s 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.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the
brake pedal pressed.
Shift into 3, 2, L, or R (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.

■AVS (adaptive variable suspension system)
The suspension can be switched for improvement in driveability. (→P. 3 2 1 )
■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 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 “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.

3-1. Using the air conditioning system and defogger
GX460_U.S.A. (OM60J00U)Rear outlets (vehicles without a re
ar automatic air conditioning sys-
tem)
Direct air flow to the left or right,
up or down.
Turn the knob to open or close
the vent.
■Air conditioning system settings
When the “ENGINE START STOP” switch is turned on, the air conditioning system
settings will be set to those that were in use the last time the “ENGINE START
STOP” switch was turned off.
Air conditioning system settings are memorized individually on each electronic key,
so the settings reproduced will be specific to the key that is used.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and ambi-
ent conditions. As a result, the following may occur.
●Immediately after the switch is pressed, the fan may stop for a while until warm
or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is on.

3-1. Using the air conditioning system and defogger
GX460_U.S.A. (OM60J00U)
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in AUTO mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning compres-
sor when the “AUTO” switch ON) can be changed.
(Customizable features →P. 7 8 2 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine
is stopped.
