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.●
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 (if equipped)
• Dynamic radar cruise control (if equipped)
• Dynamic cruise control with full-speed range (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. ●
Vehicles with a compact spare tire: Do no t tow a trailer when the compact spare tire
is installed on your vehicle. ■
Hitch
Trailer hitch assemblies have different weight capacities established by the hitch manu-
facturer. Even though the vehicle may be physically capable of towing a higher weight,
the operator must determine the maximum weig ht rating of the particular hitch assem-
bly and never exceed the maximum weight rating specified for the trailer-hitch.
Exceeding the maximum weight rating set by the trailer-hitch manufacturer can cause
an accident resulting in death or serious personal injuries.

Before using the LDA
Do not over rely on the LDA. The LDA does not drive the vehicle automatically, nor
does it reduce the amount of care you need to take. As such, the driver must always
assume full responsibility for understandin g his/her surroundings, for operating the
steering wheel to correct the driving line, and for driving safely. Also, take occasional
rests from fatigue due to driving over long periods of time, etc.
Inappropriate or negligent driving co uld lead to an unexpected accident.■
Do not drive without holding the steering wheel
While the steering control function is operating, when the system judges that the vehi-
cle is being driven without holding the steering wheel, a warning message is displayed.
(  P. 2 7 1 )
Inappropriate steering wheel operations and/or negligent driving could lead to an
unexpected accident. When driving, firmly ho ld the steering wheel and keep safe driv-
ing in mind. ■
To avoid operating the LDA by mistake
Switch the LDA off using the LDA switch when not in use. (  P. 2 7 2 )■
Situations unsuitable for LDA
Do not use the LDA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident. ●
When driving with snow tires, tire ch ains, a spare tire, or similar equipment●
When a tire with a different structure, maker, brand, or tread pattern is used. ●
When remain tread of the tire or the air pressure is insufficient●
When restructuring the suspension ●
When there are objects or structures along the roadside that might be misinterpreted
as lane markers (such as guardrails, a curb, reflector posts, etc.) ●
When driving on snowy roads ●
When pavement lane markers are difficult to see due to rain, snow, fog, sand, dust,
etc. ●
When there are visible lines on the pavement from road repairs, or if the remains of
old lane markers are still visible on the road ●
When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane ●
When driving on road surfaces that are slippery from rain, snow, etc.●
When driving in traffic lanes other than highways and freeway ●
When driving through construction areas

Vehicles with a compact spare tire: Do no t tow if your vehicle has a compact spare
tire installed. ■
When initializing the tire pressure warning system
Do not initializing tire inflation pressure wi thout first adjusting the tire inflation pressure
to the specified level. Otherwise, the tire pressure warning light may not come on even
if the tire inflation pressure is low, or it may come on when the tire inflation pressure is
actually normal. ■
Caution regarding interference with electronic devices
●
Users of any electrical medical device other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the ma nufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effe cts on the operation of such medical
devices. ●
People with implantable cardiac pacemakers,
cardiac resynchronization therapypacemak-
ers or implantable cardioverter defibrillators
should not come within 17.7 in. (450 mm) of
the tire pressure warning system initiators.
The radio waves may affect the operation of
such devices.

When trouble arises
NX300h_U_OM78007U ■
When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured:  P. 5 7 5
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered sufficiently.●
Check the tire inflation pressure and adjust to the appropriate level. ●
If the warning light does not go out even after several minutes, check that the tire infla-
tion pressure is at the specified level and carry out initialization. (  P. 5 1 8 )
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently. ■
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes). ■
When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The comp act spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning light
will not turn off even though the flat tire ha s been replaced with the spare tire. Replace
the spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure
warning light will go off after a few minutes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure
warning valve and transmitter. The tire pressure warning light will turn on if the tire infla-
tion pressure of the spare tire is low. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure
warning light will go off after a few minutes. ■
