10. Low fuel warning
This warning appears when the fuel level in
the tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the empty (0) position.
There is a small reserve of fuel remaining in
the tank when the fuel gauge reaches the
empty (0) position.
11. Low washer fluid warning
This warning appears when the washer tank
fluid is at a low level. Add washer fluid as
necessary. (See “Window washer fluid” (P.8-
10).)
12. Door/trunk open warning
This warning appears if any of the doors
and/or the trunk lid are open or not closed
securely. The vehicle icon indicates which
door or the trunk lid is open on the display.
13. Intelligent Key system warning
This warning appears if there is a malfunc-
tion in the Intelligent Key system.
If this warning appears while the engine is
stopped, the engine cannot be started. If this
warning appears while the engine is running,
the vehicle can be driven. However, in these
cases, have the system checked as soon as
possible. It is recommended you visit an
INFINITI retailer for this service.
14. Loose Fuel Cap warning
This warning appears when the fuel-filler
cap is not tightened correctly after the
vehicle has been refueled. (See “Fuel-filler
cap” (P.3-25).)
15. Tire Pressure Low - Add Air
warning
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and low tire pressure is detected. The
warning appears each time the ignition
switch is placed in the ON position as long
as the low tire pressure warning light
remains illuminated. If this warning appears,
stop the vehicle and adjust the pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Information
label. (See “Low tire pressure warning light”
(P.2-14) and “Tire Pressure Monitoring
System (TPMS)” (P.5-5).)
16. Flat Tire - Visit dealer warning
(if so equipped)
This warning appears when the low tire
pressure warning light in the meter illumi-
nates and one or more flat tires are detected
while driving. A chime also sounds for
approximately 10 seconds. (See “Low tire
pressure warning light” (P.2-14) and “Tire
Pressure Monitoring System (TPMS)” (P.5-5).)
17. Low oil pressure warning
This warning appears if low engine oil
pressure is detected. If the warning appears
during normal driving, pull off the road in a
safe area, stop the engine immediately and
call an INFINITI retailer or other authorized
repair shop.
The low oil pressure warning is not designed
to indicate a low oil level. Use the dipstick to
check the oil level. (See “Engine oil” (P.8-7).)
18. All-Wheel Drive (AWD) warning
(if so equipped)
This warning appears when the Intelligent
All-Wheel Drive (AWD) system is not func-
tioning properly while the engine is running.
The displayed message will vary depending
on the condition of the AWD system mal-
function. (See “Intelligent All-Wheel Drive
(AWD)” (P.5-123).)

INDICATORS FOR MAINTE-
NANCE
For setting the indicators for maintenance,
see the INFINITI InTouchTMOwner’s Man-
ual.
1. Engine oil and filter replacement
indicator
This indicator appears when the customer
set time comes for changing the engine oil
and filter. You can set or reset the distance
for changing the engine oil and filter.
2. Tire replacement indicator
This indicator appears when the customer
set distance comes for replacing tires. You
can set or reset the distance for replacing
tires.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, includ-
ing tire pressure checks. See “Changing
wheels and tires” (P.8-35). Many factors
including tire inflation, alignment, driv-
ing habits and road conditions affect tire
wear and when tires should be replaced.
Setting the tire replacement indicator
for a certain driving distance does not
mean your tires will last that long. Use
the tire replacement indicator as a guide
only and always perform regular tire
checks. Failure to perform regular tire
checks, including tire pressure checks
could result in tire failure. Serious vehicle damage could occur and may lead to a
collision, which could result in serious
personal injury or death.
3. Other indicator
This indicator appears when the customer
set time comes for replacing items other
than the engine oil, oil filter and tires. You
can set or reset the distance for replacing
the items.
Instruments and controls2-25

CAUTION
If the oil replacement indicator is dis-
played, change the engine oil as soon as
possible. Operating your vehicle with
deteriorated oil can damage the engine.
Warning check
The present warnings are displayed. If no
warning is present, “No Warning” is dis-
played.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions in-
terfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.)
4. Push the ignition switch while depressing the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle information
display even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the Intelligent Key
battery discharge indicator, touch the
ignition switch with the Intelligent Key
again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery as
soon as possible. (See “Intelligent Key
battery replacement” (P.8-19).)
. Make sure the area around the vehicle is
clear.
. Check fluid levels such as engine oil,
coolant, 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.
. 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. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-10).)
BEFORE STARTING THE ENGINE

5-20Starting and driving
5. Push the shift lever buttonand move
the shift lever to N (Neutral) position
while holding down the shift lock.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive Shift Control (ASC)
The adaptive shift control system automati-
cally operates when the transmission is in
the D (Drive) position and selects an appro-
priate gear depending on the road conditions
such as uphill, downhill or curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow smooth
driving with a small number of shifts.
Control on downhill roads:
The adaptive shift control system shifts to a
low gear that suits the degree of the slope,
and uses the engine braking to reduce the
number of times that the brake must be
used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel- erator pedal is depressed.
NOTE:
.
Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift to
a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by the
accelerator pedal when the vehicle is in
the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes main-
tains a lower gear for a longer period of
time than when adaptive shift control is
not operating. Engine speed will be
higher for a specific vehicle speed while
ASC system is operating than when ASC
is not operating.
WARNING
. Be sure the parking brake is fully
released 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 gear shift in place of
the parking brake. When parking, be
sure the parking brake is fully en-
gaged.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
PARKING BRAKE

5-124Starting and driving
system checked as soon as possible. It is
recommended you visit an INFINITI retailer
for this service.
The “AWD High Temp.” (high temperature)
warning
may appear while trying to free a
stuck vehicle due to increased oil tempera-
ture. The driving mode may change to Two-
Wheel Drive (2WD). If this warning is
displayed, stop the vehicle with the engine
idling, as soon as it is safe to do so. Then if
the warning turns off, you can continue
driving.
The “Tire Size Incorrect” warning
may
appear if there is a large difference between
the diameters of front and rear wheels. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that the
tires are not excessively worn.
If any warning message continues to be
displayed, have your vehicle checked as soon
as possible. It is recommended you visit an
INFINITI retailer for this service.
WARNING
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are
raised.
. If the “AWD Error” warning appears
while driving there may be a mal-
function in the AWD system. Reduce
the vehicle speed and have your
vehicle checked as soon as possible. It is recommended you visit an
INFINITI retailer for this service.
. If the “AWD Error” warning remains
on after the above operation, have
your vehicle checked as soon as
possible. It is recommended you visit
an INFINITI retailer for this service.
. The power train may be damaged if
you continue driving with the “AWD
Error” warning on.

.Do not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compound or aggressive polishing
on a base coat/clear coat paint finish may
dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting
damage or staining. Special cleaning pro-
ducts are available at an INFINITI retailer or
any automotive accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This
will prevent dirt and salt from building up
and causing the acceleration of corrosion on
the underbody and suspension. Before the
winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the win-
dows, do not use sharp-edged tools,
abrasive cleaners or chlorine-based dis-
infectant cleaners. They could damage
the electrical conductors, radio antenna
elements or rear window defroster ele-
ments.
WHEELS
Wash the wheels when washing the vehicle
to maintain their appearance.
. Clean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
. INFINITI recommends that the road
wheels be waxed to protect against road
salt in areas where it is used during winter.
CAUTION
Do not use abrasive cleaners when
washing the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
.
Do not use a cleaner that uses strong
acid or alkali contents to clean the
wheels.
. Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as
ambient temperature.
. Rinse the wheel to completely re-
move the cleaner within 15 minutes
after the cleaner is applied.
