Driving
Your 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 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 manual, whichever is
lowest. Instability of the towing vehi-
cle-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
become accustomed to the feel of
the vehicle-trailer combination.
 Reversing with a tr ailer 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
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
guide you when reversing to reduce
the risk of an accident.
 As stopping distance is increased
when towing a trailer, vehicle-to
vehicle distance 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, resulting in the trailer jackknif-
ing and a loss of vehicle control. This
is especially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden accel-
eration.
 Avoid jerky steering and sharp
turns, and slow down before making
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
cross winds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed can desta-
bilize the trailer.
 Take care when passing other vehi-
cles. Passing requires considerable
distance. After pass ing 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 effi-
ciency and charging system perfor-
mance when using engine braking,
Trailer towing tips

1724-1. Before driving
LEXUS NX300h Owners Manual_USA_M78578_en
do not put the transmission in D.
( P.180)
 Instability happens more frequently
when descending steep or long
downhill grades. Before descend-
ing, 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 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.418)
 Always place wheel blocks under
both the vehicle’s and the trailer’s
wheels when parking. Put the trans-
mission in P and apply the parking
brake. Avoid parking on a slope, but
if unavoidable, do so only after per-
forming the following:
1 Apply the brakes and keep them
applied.
2 Have someone place wheel blocks
under both the vehicle’s and trailer’s
wheels. 3
When the wheel blocks are in
place, release the brakes slowly
until the blocks absorb the load.
4 Shift into P and apply the parking
brake.
5 Turn off the hybrid system.
 When restarting after parking on a
slope:
1 With the transmission in P, start the
hybrid system. Be sure to keep the
brake pedal depressed.
2 Shift into a forward gear. If revers-
ing, shift into R.
3 If the parking brake is in manual
mode, release the parking brake.
(P.185)
4 Release the brake pedal, and slowly
pull or back away from the wheel
blocks. Stop and apply the brakes.
5 Have someone retrieve the blocks.

depending on vehicle conditions, there are
situations when EV drive mode cannot be
used. (The distance that is possible depends
on the hybrid battery [traction battery] level
and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve
the best possible fuel economy during nor-
mal driving (using the gasoline engine and
electric motor [tractio n motor]). Driving in
EV drive mode more than necessary may
lower fuel economy.
WARNING
■Caution while driving
When driving in EV drive mode, pay spe-
cial attention to the area around the vehi-
cle. Because there is no engine noise,
pedestrians, people riding bicycles or
other people and vehicles in the area
may not be aware of the vehicle starting
off or approaching them, so take extra
care while driving. Therefore, take extra
care while driving even if the acoustic
vehicle alerting system is active.
