Trailer towing tipsYour 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 va ry by state or province. Do not
exceed the posted towing speed limit.
● 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
connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in an
area away from traffic until you be come 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 yo ur hand to the right to move the
trailer to the right. (This is gene rally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to redu ce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. 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 jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.

When driving
GX460_OM_OM60J63U_(U)●
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 tr ailer wheels will be closer than the
vehicle wheels to the inside of th e 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 vehi cles. 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 th e 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 eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. ( P. 74 9 )

Always place wheel bloc ks under both the vehicle’s and the trailer’s
wheels when parking. Apply the pa rking 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 pl ace, 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 th e engine. Be sure to keep the
brake pedal pressed.
Shift into 3, 2, L, or R (if reversing).
Release the parking brake and br ake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

GX460_OM_OM60J63U_(U)Rear outlets (vehicles without a rear 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 memori zed 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 accord ing 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.

■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to in
accordance with the temperature setting, the inside temperature, outside tempera-
ture, etc.
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used.
■When the outside temperature exceeds 75 F (24 C) and the air conditioning
system is on
●In order to reduce the air conditioning power consumption, the air conditioning
system may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the “ENGINE START
STOP” switch is turned to IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
■Window defogger feature
Recirculated air mode may automatically switch to
(outside air) mode in situ-
ations where the windows need to be defogged.
■Automatic mode for air intake control (vehicles with a rear automatic air condi-
tioning system)
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the air conditioning is off, and th e fan is operating, turning automatic mode
on will activate the air conditioning system.
■Micro dust and pollen filter
●In order to prevent the windows from fogging up when the outside air is cold,
the following may occur.
• Outside air mode does not switch to (recirculated air) mode.
• The air conditioning syst em operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■When outside air temperature is below 32 F (0 C)
The cooling and dehumidification function may not operate even when the “A/C”
button is pressed.

■When the “A/C ON” in the multi-information display (accessory meter) flashes
Press
the “A/C” button and turn off the cooling and dehumidification function and
turn it on again. There may be a problem in the air conditioning system if the indica-
tor light continues to flash. Turn the air co nditioning system off and have it inspected
by your Lexus dealer.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. 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 op eration of the air conditioning compres-
sor when the “AUTO” switch ON) can be changed.
(Customizable features P. 7 8 8 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operatio n 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.
