CAUTION
.Keep the interior of the vehicle as
quiet as possible to hear the tone
clearly. Excessive noise (such as
audio system volume or an open
vehicle window) will interfere
with the tone and it may not be
heard.
. Keep the sonar (located on the
bumper fascia) free from snow,
ice and large accumulations of
dirt (do not clean the sonar with
sharp objects). If the sonar is
covered, it will affect the accuracy
of the sonar system.
. The sonar system may not oper-
ate correctly if a license plate
cover is installed.
The sonar system sounds a tone to warn
the driver of obstacles near the bumper.
The sonar indicator will also appear in the
touch screen display. (
“Sonar indica-
tor” page 5-49.) The system detects front
obstacles when the shift lever is in the
position or
position and both front and

position.
The system may not detect objects at
speeds above 6 MPH (10 km/h) and may
not detect certain angular or moving
objects.
Refer to the illustration for approximate
zone coverage areas. As you move closer
to the obstacle, the rate of the tone
increases. When you move even closer
to the obstacle, the tone will sound
continuously.
The sensitivity level of the sonar can be
adjusted (higher or lower) in the sonar
setting display. (

. Transmission oil temperature is 284°F
(140°C) or higher:
If the transmission oil temperature
increases to over 284°F (140°C), the
color of the meter display changes to
red. However, the vehicle can continue
to be driven until the temperature
reaches 295°F (146°C). If the oil tem-
perature exceeds 284°F (140°C) while
driving (the color of the meter dis-
played in red), change both the trans-
mission oil and the differential oil after
driving because these fluids have
deteriorated because of the heat.

ways use run-flat tires of the specified
size on all four wheels. Mixing tire sizes or
construction may reduce vehicle handling
stability. If necessary, contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure infor-
mation on the touch screen display and
adjust pressure of each tire properly. See
the separate Multi Function Display Own-
er’s Manual.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire
pressures as described earlier in this
section. If the tire becomes under-inflated
while driving, the low tire pressure warn-
ing light will come on. If the tire becomes
flat while driving, the low tire pressure
warning light and the run-flat tire warn-
ing display will come on.
Low tire pressure:
NOTICE
.Never install tire chains on a
punctured run-flat tire, as this
could damage your vehicle.
. Avoid driving over any projection
or pothole, as the clearance be-
tween the vehicle and the ground
is smaller than normal.
. Do not enter an automated car
wash with a punctured run-flat
tire.
. It is recommended you have the
punctured tire replaced by a GT-R
certified NISSAN dealer as soon
