GX460_OM_OM60Q84U_(U)4-1. Before driving
Your vehicle will handle differently when
towing a trailer. Help to avoid an acci-
dent, death or serious injury, keep the following in mind when towing:
●Speed limits for towing a trailer vary by state or province. Do not exceed the
posted towing speed limit.
●Lexus recommends that the vehicle-traile r speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exce ed this limit, the posted towing speed
limit or the speed limit for your trailer as set forth in your trailer owner’s man-
ual, 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 con-
nections. Recheck after driving a short distance.
●Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become acc ustomed to the feel of the vehicle-
trailer combination.
●Reversing with a trailer attached is di fficult 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 your hand to the right to move the trailer to the right.
(This is generally opposite to reversing without a trailer attached.) Avoid sharp
or prolonged turning. Have someone gu ide you when reversing to reduce the
risk of an accident.
●As stopping distance is increased when towing a trailer, vehicle-to-vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length.
●Avoid sudden braking as you may skid, re sulting in the trailer jackknifing and
loss of vehicle control. This is especi ally true on wet or slippery surfaces.

GX460_OM_OM60Q84U_(U)4-5. Using the driving support systems
CAUTION
■The rear height control air suspension must be turned off
Be sure to observe the following precautions. Otherwise, the automatic leveling func-
tion may cause vehicle height to change, an
d you may catch part of your body in the
vehicle, resulting in an accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flatbed truck, tu rn off the rear height control air suspen-
sion and stop the engine.
●When the vehicle must be towed or disconnect ing a trailer, put the vehicle height in N
mode and turn off the rear he ight control air suspension.
●When the vehicle is stuck, turn off the rear height control air suspension.
■Selecting the correct height mode
●HI mode should only be used when drivin g on rough roads, for example when driving
off-road.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Before lowering vehicle height, check that there is no one under the vehicle.
NOTICE
■Be careful in any place where overhead space is limited
The vehicle height will rise when a higher mode is selected or cargo is unloaded. This
may cause damage to the vehicle.
■Do not select LO mode when driving on bumpy roads
If the underbody of the vehicle touches a rugged road surface, the vehicle may be
damaged.
■Changing vehicle height
Do not change vehicle height frequently.
The compressor may overhe at and stop operation.
■When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven road driv-
ing.
