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 on 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 “Battery” (P.8-
11).) .
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/
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. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-11).) 1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N
(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push

ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tem-
perature with heavy loads, such as when
towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function may
be automatically turned OFF for a short
time (the blower will continue to oper-
ate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shift or upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function
will automatically be turned back ON. If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tempera-
ture gauge does not return to the normal
range from the H position, this may
indicate a malfunction. Move the vehicle
off the road to a safe area and allow the
engine to cool. If after checking the oil
and coolant, the
remains on or
engine coolant temperature does not
return to the normal range, do not
continue to drive. It is recommended
you contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic, which could increase the chance of a
collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. See
“If your vehicle overheats” (P.6-14).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.

DRIVING THE VEHICLE

5-124Starting and driving
The 4WD shift switch is used to select the
4WD mode depending on the driving condi-
tions. There are 3 types of drive modes
available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode, AUTO,
4H and 4L.
You must depress the 4WD shift switch to
select 4L, and the vehicle MUST be sta-
tionary and the shift lever in the N (Neutral)
position when changing into or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warning
light turns off. Otherwise, the vehicle
could unexpectedly move even if the
automatic transmission is in the P
(Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illuminated or
turn off before shifting the transmis-
sion into gear. If the shift lever is
shifted from the N (Neutral) position
to any other gear while the 4LO and
4HI indicators are blinking alter- nately, the vehicle may move unex-
pectedly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed, as it
will cause increased fuel consumption
and higher oil temperatures, and
could damage drivetrain component.
Speeds over 62 MPH (100 km/h) in
4HI is not recommended.
. The 4LO position provides maximum
traction. Avoid raising vehicle speed
excessively, as the maximum speed is
approximately 31 MPH (50 km/h).
. When driving straight, shift the 4WD
shift switch to the AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or rever-
sing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while driv-
ing on steep downhill grades. Use the
engine brake and low automatic
transmission gears for engine brak-
ing. .
Do not operate the 4WD shift switch
(between AUTO and 4H) with the
rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in 4HI or
4LO may cause unnecessary noise
and tire wear. INFINITI recommends
driving in the AUTO position under
these conditions.
. The 4WD transfer case may not be
shifted between 4HI and 4LO at low
ambient temperatures and the 4LO
and 4HI indicators may blink even
when the 4WD shift switch is shifted.
After driving for a while you can
change the 4WD shift switch be-
tween 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under the
tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.
. If it is difficult to free the vehicle, repeat
forward and backward movement to
increase the movement.

If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light blinks
rapidly during operation, stop the vehicle in a
safe place immediately. Then if the light
turns off after a while, you can continue
driving.
A large difference between the diameters of
front and rear wheels will make the 4WD
warning light blink slowly (about once per
two seconds). Change the 4WD shift switch
to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes on or
blinks slowly during operation or
rapidly after stopping the vehicle for
a while, have your vehicle checked as
soon as possible. It is recommended
you visit an INFINITI retailer for this
service.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warn-
ing light turns on.
. When the 4WD warning light comes
on, the 2WD mode may be engaged
even if the 4WD shift switch is in AUTO or 4H. Be especially careful
when driving. If corresponding parts
are malfunctioning, the 4WD mode
will not be engaged even if the 4WD
shift switch is shifted.
. Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces
in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
shift lever to the N (Neutral)
position and shift the 4WD shift
switch to AUTO.
. If the 4WD warning light is still 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 transfer case may be damaged if
you continue driving with the warn-
ing light blinking.
Starting and driving5-127

.Wax your vehicle only after a thorough
washing. Follow the instructions sup-
plied with the wax.
. 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.
