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
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 driving.
If necessary, pull to the side of the road at a
safe place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
WARNING
∙ Be sure the parking brake is fully releasedbefore 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

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
