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 condition,
have the transmission checked and repaired,
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 will apply auto-
matically if the ignition switch is placed in the
OFF position when the brake force is main-
tained by the automatic brake hold function.
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.

The ProPILOT Assist system has the follow-
ing two functions:
1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of two
cruise control modes:
• Conventional (fixed speed) cruise control
mode: For cruising at a preset speed
NOTE:Steering assist is not available in the conven-
tional (fixed speed) cruise control mode.
•Vehicle-to-vehicle distance control mode:
The ICC system maintains a selected dis-
tance from the vehicle in front of you within
the speed range of 0 to 90 mph (0 to 144
km/h) up to the set speed. The set speed
can be selected by the driver between 20 to
90 mph (30 to 144 km/h). When the ve-
hicle ahead slows to a stop, your vehicle
gradually decelerates to a standstill. When
the vehicle is stopped, the ICC system
maintains braking force to keep your ve-
hicle stopped.
NOTE:When your vehicle is stopped for less than 3
seconds and the vehicle ahead begins to
move, your vehicle will start moving again
automatically.

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar sen-
sor may detect vehicles in a different lane, or
may temporarily not detect a vehicle traveling
ahead. This may cause the radar system to
decelerate or accelerate the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
Automatic cancellation
The following are conditions in which the ICC
system may be temporarily unavailable. In
these instances, the ICC system may not can-
cel and may not be able to maintain the se-
lected following distance from the vehicle
ahead.Condition A
Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and your
vehicle is traveling below the speed of 15
mph (25 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shift lever is not in the D (Drive) position or manual shift mode.
• The electronic parking brake is applied.
