WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping. ■
When driving the vehicle ●
Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing th e accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only
slightly. This allows you to depress th e brake and accelerator pedals properly.
• Depress the brake pedal using your righ t foot. Depressing the brake pedal using
your left foot may delay response in an emergency, resulting in an accident. ●
The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement. ●
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.

224 4-1. Before driving
RX450h_U_OM0E013U 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-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 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 accustomed 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 right. (This
is generally opposite to reversing without a trailer attached.) Avoid sharp or
prolonged turning. Have someone guid e 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 traile r jackknifing and a
loss of vehicle control. This is especially true on wet or slippery surfaces. ●
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 traile r wheels will be closer than the vehicle
wheels to the inside of the turn. Comp ensate by making a wider than normal
turning radius. ●
Slow down before making a turn, in cross winds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer. ●
Take care when passing other vehicles. Passing requires considerable dis-
tance. After passing a vehicle, do not forget the length of your trailer, and be
sure you have plenty of room before changing lanes.Trailer towing tips

RX450h_U_OM0E013U WA R N I N G ■
Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance with the
trailer’s characteristics and op erating conditions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer stability, brake setting and performance, and the hitch. Your vehicle
will handle differently when towing a trailer. ■
To avoid accident or injury ●
Do not exceed the TWR, unbrak ed TWR, GCWR, GVWR or GAWR.●
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with suffi-
cient capacity is required. ●
Adjust the tongue weight within the approp riate range. Place heavier loads as close
to the trailer axle as possible. ●
Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed limit
for your trailer as set forth in your trailer owner’s manual, whichever is lowest. Slow
down sufficiently before making a turn, in cr oss winds, on wet or slippery surface, etc.
to help avoid an accident. If you experience a vehicle-trailer instability from reducing
a certain speed, slow down and make sure you keep your vehicle speed under the
speed of which you expe rience the instability.●
Do not make jerky, abrupt or sharp turns. ●
Do not apply the brakes suddenly as you ma y skid, resulting in ja ckknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces. ●
Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities. ●
Do not use the following systems when trailer towing.
•Cruise control
*• Dynamic radar cruise control
*• Dynamic radar cruise cont rol with full-speed range
*• LDA (Lane-Departure Alert with steering control)
*• LKA (Lane-Keeping Assist)
*• PCS (Pre-Crash Safety system)
*• BSM (Blind Spot Monitor)
* : If equipped ●
Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descen ding steep or long downhill grades.●
Vehicle-trailer instability is more likely on steep long downhills. Before descending
steep or long downhill grades, slow down and downshift. Do not make sudden down-
shifts when descending stee p 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. ●
Do not tow a trailer when the compact spare tire is installed on your vehicle.
