trailer INFINITI QX50 2019 Owners Manual

∙ Use only an original equipment type fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emission
control system. An incorrect cap can re-
sult in a serious malfunction and possible
injury. It could also cause the
Mal-
function Indicator Light (MIL) to come
on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.
∙ Do not fill a portable fuel container in the vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are filling it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
∙ Do not use a fuel containing more than15% ethanol in your vehicle. For addi-
tional information, refer to “Fuel recom-
mendation” in the “Technical and con-
sumer information” section of this
manual.
∙ The Loose Fuel Cap warning message will be displayed if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly after the Loose Fuel Cap
warning is displayed may cause the Mal-
function Indicator Light (MIL) to
illuminate.
∙ Failure to tighten the fuel-filler cap prop- erly may cause the
Malfunction In-
dicator Light (MIL) to illuminate. If
the
light illuminates because the
fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive
the vehicle. The
light should turn
off after a few driving trips. If the
light does not turn off after a few driving
trips, have the vehicle inspected. It is rec-
ommended that you visit an INFINITI re-
tailer for this service. ∙ For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” section of
this manual.
∙ If fuel is spilled on the vehicle body, flush it away with water to avoid paint
damage.

could result in serious injury or death.
∙ Do not use the MOD system when tow- ing a trailer. The system may not function
properly.
∙ Excessive noise (for example, audio sys- tem volume or open vehicle window) will
interfere with the chime sound, and it
may not be heard.
∙ The MOD system performance will be limited according to environmental con-
ditions and surrounding objects such as:
– When there is low contrast between background and the moving objects.
– When there is a blinking source of light.
– When strong light such as another ve- hicle’s headlight or sunlight is present.
– When camera orientation is not in its usual position, such as when a mirror is
folded. – When there is dirt, water drops or
snow on the camera lens.
– When the position of the moving ob- jects in the display is not changed.
∙ The MOD system might detect flowing water droplets on the camera lens, white
smoke from the muffler, moving shad-
ows, etc.
∙ The MOD system may not function prop- erly depending on the speed, direction,
distance or shape of the moving objects.
∙ If your vehicle sustains damage to the parts where the camera is installed, leav-
ing it misaligned or bent, the sensing zone
may be altered and the MOD system may
not detect objects properly.
∙ When the temperature is extremely high or low, the screen may not display objects
clearly. This is not a malfunction.
NOTE:
The blue MOD icon will change to orange if
one of the following has occurred: ∙ When the system is malfunctioning.
∙ When the component temperature reaches a high level (icon will blink).

WARNING
∙ Do not leave children or adults whowould normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally injure themselves or others through
inadvertent operation of the vehicle.
Also, on hot, sunny days, temperatures in
a closed vehicle could quickly become
high enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death. ∙ If you suspect that exhaust fumes are en-
tering the vehicle, drive with all windows
fully open, and have the vehicle inspected
immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the engine running for any extended length of time.
∙ Keep the rear vent windows, liftgates, doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
∙ If electrical wiring or other cable connec- tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer’s recommendation to
prevent carbon monoxide entry into the
vehicle.
∙ The exhaust system and body should be inspected by a qualified mechanic
whenever: a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
∙ The exhaust gas and the exhaust systemare very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
∙ Do not stop or park the vehicle over flam- mable materials such as dry grass, waste
paper or rags. They may ignite and cause
a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2-wheel drive models are
less capable than All-Wheel Drive (AWD)
models for rough road driving and extrication
when stuck in deep snow or mud, or the like.
Please observe the following precautions:
WARNING
∙ Spinning the front wheels on slipperysurfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD to
the 2WD mode. This could reduce the
traction. Be especially careful when tow-
ing a trailer (AWD models).
∙ Drive carefully when off the road and avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers in
position when driving over rough terrain.
∙ Do not drive across steep slopes. Instead drive either straight up or straight down
the slopes. Off-road vehicles can tip over
sideways much more easily than they can
forward or backward.
∙ Many hills are too steep for any vehicle. If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over.
∙ Do not shift gears while driving on down- hill grades as this could cause loss of con-
trol of the vehicle. ∙ Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
∙ If your engine stalls or you cannot make it to the top of a steep hill, never attempt to
turn around. Your vehicle could tip or roll
over. Always back straight down in R
(Reverse) gear and apply brakes to con-
trol your speed.
∙ Heavy braking going down a hill could cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
∙ Unsecured cargo can be thrown around when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
∙ Secure heavy loads in the cargo area as far forward and as low as possible. Do not
equip the vehicle with tires larger than
specified in this manual. This could cause
your vehicle to roll over.
Starting and driving5-11

∙ Remember not to drive at high speeds forextended periods of time in lower than
8th gear. This reduces fuel economy.
When shifting up
Use the + (up) side paddle shifter. (Shifts to
higher range.)
When shifting down
Use the (down) side paddle shifter. (Shifts
to lower range.)
∙ The transmission will automatically downshift the gears. (For example, if you
select the 3rd range, the transmission will
shift down between the 3rd and 1st
gears.)
∙ Moving the shift lever rapidly to the same side twice will shift the ranges in succes-
sion.
When canceling the manual shift mode
Move the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode. ∙ In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age or loss of control. ∙
When this situation occurs, the Continu-
ously Variable Transmission (CVT) posi-
tion indicator will blink and the chime
will sound.
∙ In the manual shift mode, the transmis-
sion may shift up automatically to a
higher range than selected if the engine
speed is too high. When the vehicle
speed decreases, the transmission auto-
matically shifts down and shifts to 1st
gear before the vehicle comes to a stop.
∙ CVT operation is limited to automatic drive mode when CVT fluid temperature
is extremely low even if manual shift
mode is selected. This is not a malfunc-
tion. When CVT fluid warms up, manual
mode can be selected.
∙ When the CVT fluid temperature is high, the shift range may upshift in lower rpm
than usual. This is not a malfunction.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the ac-
celerator pedal to the floor. This shifts the
transmission down into a lower gear, de-
pending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, when climb-
ing steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automatically
to reduce the chance of transmission dam-
age. Vehicle speed can be controlled with the
accelerator pedal, but the engine and vehicle
speed may be limited.
Fail-safe
When the fail-safe operation occurs, the
Continuously Variable Transmission will not
be shifted into the selected driving position.
If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, refer to “Malfunction In-
dicator Light (MIL)” in the “Instruments and
controls” section of this manual. This will oc-
cur even if all electrical circuits are function-
ing properly. In this case, place the ignition
Starting and driving5-23

∙When the electronic parking brake is fre-
quently applied and released in a short
period of time, the parking brake may
not operate in order to prevent the park-
ing brake system from overheating. If
this occurs, operate the electronic park-
ing brake switch again after waiting ap-
proximately 1 minute.
∙ If the electronic parking brake must be
applied while driving in an emergency,
pull up and hold the parking brake
switch. When you release the parking
brake switch, the parking brake will be
released.
∙ While pulling up the electronic parking
brake switch during driving, the parking
brake is applied and a chime sounds. The
electronic parking brake indicator light
(red) in the meter and in the parking
brake switch illuminates. This does not
indicate a malfunction. The electronic
parking brake indicator light (red) in the
meter and in the parking brake switch
turns off when the parking brake is re-
leased. ∙
When pulling the electronic parking
brake switch up with the ignition switch
in the OFF or AUTO ACC position, the
parking brake switch indicator light will
continue to illuminate for a short period
of time.
WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
∙ Release the parking brake switch as soon as the engine is delivering enough torque
to the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-
matic brake hold can be displayed on the
vehicle information display.
WARNING
∙ The automatic brake hold function is not
designed to hold the vehicle on a steep hill
or slippery road. Never use the automatic
brake hold when the vehicle is stopped on
a steep hill or slippery road. Failure to do
so may cause the vehicle to move.
∙ When the automatic brake hold function is activated but fails to maintain the ve-
hicle at a standstill, depress the brake
pedal to stop the vehicle. If the vehicle
unexpectedly moves due to outside con-
ditions, the chime may sound and auto-
matic brake hold warning may illuminate
in the vehicle information display.
∙ Be sure to deactivate the automatic brake hold function when using a car
wash or towing your vehicle.

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the warn-
ings and instructions for proper use of the
LDP system could result in serious injury or
death.
∙ The LDP system may activate if youchange lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
∙ Because the LDP may not activate under the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
∙ The LDP system will not operate at speeds below approximately 37 mph
(60 km/h) or if it cannot detect lane
markers.
∙ Do not use the LDP system under the fol- lowing conditions as it may not function
properly: – During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift or tempo- rary lane.
– When driving on roads where the lane width is too narrow.
