ECO mode INFINITI QX50 2023 Service Manual

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, see “Malfunction Indica-
tor Light (MIL)” (P. 2-15). This will occur
even if all electrical circuits are functioning
properly. In this case, place the ignition
switch in the OFF position and wait for
10 seconds. Then place the ignition switch
back in the ON position. The vehicle should
return to its normal operating condition. If it
does not return to its normal operating con-
dition, have the transmission checked and re-
paired, if necessary. It is recommended that
you visit an INFINITI retailer for this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of
a collision. Be especially careful when driv-
ing. If necessary, pull to the side of the road
at a safe place and allow the transmission
to return to normal operation, or have it
repaired if necessary.
WARNING
• Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
• Do not release the parking brake from
outside the vehicle.
• Do not use the shift lever in place of the
parking brake. When parking, be sure the
parking brake is fully engaged. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
The electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.
The driver’s seat belt needs to be fastened.
WARNING
• The electronic parking brake will not be
automatically applied when the engine is
stopped without using the ignition
switch (for example, by engine stalling).
Without the vehicle stationary, the elec-
tronic parking brake will not be auto-
matically applied even if the engine is
turned off with the ignition switch.

• The radar sensors may be blocked by tem-porary ambient conditions such as splash-
ing water, mist or fog. The blocked condi-
tion may also be caused by objects such as
ice, frost or dirt obstructing the radar sen-
sors. Check for and remove objects ob-
structing the area around the radar
sensors.
• Do not attach stickers (including transpar- ent material), install accessories or apply
additional paint near the camera unit or
radar sensors.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the area around the radar sensors. Do not touch the camera
lens or remove the screw located on the
camera unit. It is recommended that you
visit an INFINITI retailer if the camera unit

ICC system malfunction
If the ICC system malfunctions, it will be
turned off automatically, a chime will sound,
and the speed control status warning
(orange) will illuminate.
Action to take:
If the warning light comes on, stop the vehicle
in a safe place. Turn the engine off, restart
the engine and set the ICC system again. If it
is not possible to set the ICC system or the
indicator stays on, it may be a malfunction.
Although the normal driving can be contin-ued, the ICC system should be inspected. It is
recommended that you visit an INFINITI re-
tailer for this service.
NOTE:
If the ICC system is temporarily unavailable,
the conventional cruise control mode may
still be used. For additional information, see
“Conventional (fixed speed) cruise control
mode” (P. 5-101).
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around
the sensor.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.
• Do not attach metallic objects near the sensor area (brush guard, etc.). This could
cause failure or malfunction.
• Do not alter, remove, or paint the front bumper. Before customizing or restoring the front
bumper, it is recommended that you visit an
INFINITI retailer.
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the systems
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar-
ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit an
INFINITI retailer.

STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately.
• The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads. •
The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• It is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in the
traveling lane, and be in control of the
vehicle at all times. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering
Assist. To avoid serious injury or death,
do not rely on the system to prevent
accidents or to control the vehicle’s
speed in emergency situations. Do not
use the Steering Assist except in appro-
priate road and traffic conditions.Steering Assist operation
The Steering Assist controls the steering sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for
vehicles with ProPILOT Assist)” (P. 5-84).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the vehicle is driven at speeds under 37 mph
[60 km/h])
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering
assist function is disabled after the wiper
operates for approximately 10 seconds).
