Reverse tilt-down feature (if so
equipped)
The reverse tilt-down feature will turn both
outside mirror surfaces downward to pro-
vide better rear visibility close to the vehicle
when the mirror control switch is in either
the L or R position.
The mirrors automatically return to their
original position when you shif t out of R
(Reverse).
The outside mirror surfaces will return to
their original position when one of the fol-
lowing has occurred:
• The shif t lever is moved to any positionother than R (Reverse).
• The outside mirror control switch is set to the neutral or center position.
• The ignition switch is placed in the OFF position.
NOTE:
If the outside mirror control switch is in
the center (neutral) position, mirror sur-
face will NOT turn downward when the
shif t lever is moved to R (Reverse).
For additional information regarding this
feature, see “Memory seat” (P. 3-30).
The memory seat system has three features:
• Memory storage function (Key-link)
• Memory storage function (Switch)
• Entry/exit function
Key-link, when enabled, automatically re-
tains the driver’s last seat, automatic steer-
ing wheel, and outside mirror positions for
that specific key when the ignition is turned
from ON to OFF.
Each memory switch button (1 or 2) on the
driver’s door can also store one additional
position which is independent of the key-
linked position.
MEMORY STORAGE FUNCTION
(key-link)
Use the following process to setup key-link:
1. Unlock the vehicle with the desired Intel- ligent Key while the ignition is OFF.
2. Place the ignition in the ON position.
3. Within the “Settings” menu of the vehicle information display, select “Key-Linked
Settings” and press the OK button on the
steering switch.
4. While in the menu, press the OK button on the steering switch to turn the sys-
tem ON/OFF. Once step 4 is completed, every time the
ignition is switched from ON to OFF, the
memory positions of the driver’s seat, au-
tomatic steering wheel and the outside
mirrors are linked to the Intelligent Key.
Follow the same procedure if you want
to link the 2nd, 3rd or 4th Intelligent Key.
NOTE:
If new memory positions are set prior to
turning the ignition from ON to OFF, the
previously linked memory positions for
the respective key will be overwritten by
new positions.
Recalling Intelligent Key memory
positions
If the “Key-Linked Settings” are enabled in
the vehicle information display for that par-
ticular key, every time you enter the vehicle
the driver’s seat, automatic steering wheel,
and outside mirrors will automatically
move to the driver’s last position of the
respective Intelligent Key.
NOTE:
The key-linked memory positions can be
different from the positions stored in the
memory switch (1 or 2).

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and window washer fluid
as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust head restraints/headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-8). 1. Apply the parking brake.
