2020 INFINITI QX50 trailer

∙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 warnings
and instructions for proper use of the LDP sys-
tem 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.
– When driving without normal tire conditions (for example, tire wear, low
tire pressure, installation of spare tire,
tire chains, non-standard wheels).
– When the vehicle is equipped with nonoriginal brake parts or suspension
parts.
– When you are towing a trailer or other vehicle.
The system may not function properly un-
der the following conditions:
∙ On roads where there are multiple paral- lel lane markers; lane markers that are
faded or not painted clearly; yellow
painted lane markers; non-standard lane
markers; or lane markers covered with
water, dirt, snow, etc. ∙ On roads where discontinued lane mark-
ers are still detectable.
∙ On roads where there are sharp curves.
∙ On roads where there are sharply con- trasting objects, such as shadows, snow,
water, wheel ruts, seams or lines remain-
ing after road repairs. (The LDP system
could detect these items as lane
markers.)
∙ On roads where the traveling lane merges or separates.
∙ When the vehicle’s traveling direction does not align with the lane marker.
∙ When traveling close to the vehicle in front of you, which obstructs the lane
camera unit detection range.
∙ When rain, snow or dirt adheres to the windshield in front of the lane camera
unit.
∙ When the headlights are not bright due to dirt on the lens or if the aiming is not
adjusted properly.

– When a sudden change in brightness occurs (e.g., when the vehicle enters or
exits a tunnel or under a bridge). ∙ Do not use the BSI system under the fol-
lowing conditions because the system
may not function properly:
– During bad weather (e.g., rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving with a tire that is not within normal tire conditions (e.g., tire
wear, low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BSI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
5-60Starting and driving

∙ The system may not detect the vehicle infront of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead. ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The radar sensor will not detect the following
objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The sensor generally detects the signals re-
turned from the vehicle ahead. Therefore, if
the sensor cannot detect the reflection from
the vehicle ahead, the ICC system may not
maintain the selected distance.
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When your vehicle is towing a trailer, etc.
∙ When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle. The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically be
canceled. If the sensor is covered with ice, a
transparent or translucent vinyl bag, etc., the
ICC system may not detect them. In these
instances, the vehicle-to-vehicle distance
control mode may not cancel and may not be
able to maintain the selected following dis-
tance from the vehicle ahead. Be sure to
check and clean the sensor regularly.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the vehicle-to-vehicle distance
detection mode to maintain the selected dis-
tance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the centerline of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.
If this occurs, the ICC system may warn you
by blinking the system indicator and sound-
ing the chime. The driver may have to manu-
ally control the proper distance away from
vehicle traveling ahead.
5-90Starting and driving

∙ Always pay attention to the operation ofthe vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(following distance) or selected vehicle
speed under some circumstances.
∙ The system may not detect the vehicle in front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following
conditions:
– On roads with heavy, high-speed traf- fic or sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads – When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
