increase the movement.
. If the vehicle is stuck deep in mud, tire
chains may be effective.
CAUTION
. Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
. Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.

4WD SHIFT SWITCH
.Shift the 4WD shift switch to either the
AUTO, 4H or 4L position, depending on
driving conditions.
. With the switch set to the AUTO posi-
tion, distribution of torque to the front
and rear wheels changes automatically,
depending on road conditions encoun-
tered [ratio; 0 : 100 (2WD) ?50 : 50
(4WD)]. This results in improved driving
stability.
. If the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the ignition switch is
placed in the OFF position while in the AUTO, 4H or 4L, you may feel a jolt.
This is not abnormal.
. When the vehicle is stopped after
making a turn, you may feel a slight
jolt after the shift lever is shifted to N
(Neutral) or P (Park) position. This
occurs because the transfer clutch is
released and not because of a malfunc-
tion.
CAUTION
. 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 reversing.
. Do not shift the 4WD shift switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears for engine braking.
. Do not operate the 4WD shift switch with
the rear wheels spinning.
. Before placing the 4WD shift switch in
the 4H position from AUTO, ensure the
vehicle speed is less than 62 MPH (100
km/h). Failure to do so can damage the
4WD system.

.Never shift the 4WD shift switch be-
tween 4L and 4H while driving.
. Engine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery
surfaces with the 4WD shift switch in
AUTO.

4WD shift indicator
4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within 1
second after placing the ignition switch in
the ON position.
While the engine is running, the 4WD shift
indicator will illuminate the position se-
lected by the 4WD shift switch. (See the
4WD shift procedure list shown in the
“INFINITI all-mode 4WD
®system” earlier in
this section.)
. The 4WD shift indicator may blink while shifting from one drive mode to the
other. When the shifting is completed,
the 4WD shift indicator will come on. If
the indicator does not come on im-
mediately, make sure the area around
the vehicle is safe, and drive the
vehicle straight, accelerate or decele-
rate or move the vehicle in reverse,
then shift the 4WD shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.
4WD WARNING LIGHT
Warning light Comes on or blinks
when:
Illuminates There is a mal-
function in the 4WD system
Blinks rapidly The transfer case
oil temperature is abnormally high
Blinks slowly The difference in
wheel rotation is large
The 4WD warning light is located in the
meter.
The 4WD warning light comes on when the
ignition switch is placed in the ON posi-
tion. It turns off soon after the engine is
started.

5-106Starting and driving
If any malfunction occurs in the 4WD
system when the ignition switch is placed
in the ON position, the 4WD warning light
will either remain illuminated or blink.
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 by an INFINITI
retailer as soon as possible.
. Shifting between 4HI and 4LO is not
recommended when the 4WD warning 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 by an INFINITI retailer as soon
as possible.
. The transfer case may be damaged if you
continue driving with the warning light blinking.

WARNING
.Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
. Never leave the engine running while the
vehicle is unattended.
. Do not leave children unattended inside
the vehicle. They could unknowingly
activate switches or controls. Unat-
tended children could become involved
in serious accidents. .
Safe parking procedures require that
both the parking brake be applied and
the transmission be placed in the P
(Park) position. Failure to do so could
cause the vehicle to move unexpectedly
or roll away and result in an accident.
. Make sure the automatic transmission
shift lever has been pushed as far
forward as it can go and cannot be
moved without depressing the foot
brake pedal.
1. Firmly apply the parking brake.
2. Move the shift lever to the P (Park)
position.
3. To help prevent the vehicle from rolling into the street when parked on a
sloping drive way, it is a good practice
to turn the wheels as illustrated.
.HEADED DOWNHILL WITH CURB:*1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
.HEADED UPHILL WITH CURB:*2
Turn the wheels away from the curb and
move the vehicle back until the curb
side wheel gently touches the curb.
.HEADED UPHILL OR DOWNHILL, NOCURB:
*3
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Push the ignition switch to the OFF position.

The TOW MODE should be used when
pulling a heavy trailer or hauling a heavy
load. Driving the vehicle in the TOW MODE
with no trailer/load or light trailer/light
load will not cause any damage. However,
fuel economy may be reduced, and the
transmission/engine driving characteris-
tics may feel unusual.
Push the TOW MODE switch to activate
TOW MODE. The indicator light on the TOW
MODE switch illuminates when the TOW
MODE is selected. Push the TOW MODE
switch again to turn the TOW MODE OFF.
TOW MODE is automatically canceled when
the ignition switch is placed in the OFFposition.
SIC4454
For driving or starting the vehicle on snowy
roads or slippery areas, turn the SNOW
mode on.
To turn the SNOW mode on, push the
SNOW mode switch. The SNOW mode
indicator light on the meter panel will
illuminate. When the SNOW mode is
activated, engine output is controlled to
avoid wheel spin.
To turn the SNOW mode off, push the
switch and the indicator on the meter
panel will turn off. Turn the SNOW mode off
for normal driving and fuel economy.

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
.Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip based
on vehicle speed (traction control func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes so note the following:
.
The road may be slippery or the system
may determine some action is required
to help keep the vehicle on the steered
path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn off
the system, the VDC system still operates
to prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
and the VDC warning light
will not
flash. The VDC system is automatically
reset to on when the ignition switch is
placed in the off position then back to the on position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
illuminates (for 4WD models).
See
“Vehicle Dynamic Control (VDC) warn-
ing light” in the“2. Instruments and
controls” section and “Vehicle Dynamic
Control (VDC) off indicator light” in the“2.
Instruments and controls” section.
The computer has a built-in diagnostic
feature that tests the system each time you
start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
. The VDC system is designed to help
improve driving stability but does not
prevent accidents due to abrupt steering
operation at high speeds or by careless
or dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery

SIC2574
Push the switch on to warn other drivers
when you must stop or park under
emergency conditions. All turn signal lights
will flash.
WARNING
.If stopping for an emergency, be sure to
move the vehicle well off the road.
. Do not use the hazard warning flashers
while moving on the highway unless
unusual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the
ignition switch in any position.
When an impact that could activate the
supplemental air bags is detected, the
hazard warning flasher lights blink auto-
matically. If the hazard warning flasher
switch is pushed twice, the hazard warning
flashers will turn off.
WARNING
Do not turn the hazard warning flasher
switch to off until you can make sure that it
is safe to do so. Also, the hazard flasher
warning may not blink automatically de-
pending on the force of impact.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada)
for details.

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls” section,“TIRE PRESSURE infor-
mation” in the“4. Monitor, climate, audio,
phone and voice recognition systems”
section and “Tire Pressure Monitoring
System (TPMS)” in the“5. Starting and
driving” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa- tion is displayed on the monitor screen
while driving, avoid sudden steering
maneuvers or abrupt braking, reduce
vehicle speed, pull off the road to a safe
location and stop the vehicle as soon as
possible. Driving with under-inflated
tires may permanently damage the tires
and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light OFF. If
the light still illuminates while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

Installing the spare tire
The full-size temporary use only spare tire
(if so equipped) is designed for emergency
use. (See specific instructions under the
heading“Wheels and tires” in the“8.
Maintenance and do-it-yourself” section.)
1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence as illustrated (
*1,*2,*3,
*4,*5,*6) until they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
. Incorrect wheel nuts or improperly tigh-
tened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 98 ft-lb (133 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
