●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. (See “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section.)1. Apply the parking brake.
2. Move the selector lever to the P (Park) or
N (Neutral) position. (P is recommended.)
The starter is designed not to operate unless
the selector lever is in either of the above
positions.
3. Push the ignition switch to the ON posi-tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in
extremely cold weather or when restart-
ing, depress the accelerator pedal a little
(approximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After 5
or 6 seconds, stop cranking by pushing
the ignition switch to OFF. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the accelerator pedal
by depressing the brake
pedal and pushing the push-button igni-
tion switch to start the engine. If the
engine starts, but fails to run, repeat the
above procedure.
CAUTION
Do not operate the starter for more than 15
seconds at a time. If the engine does not start,
push the ignition switch to OFF and wait 10
seconds before cranking again, otherwise the
starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the en-
gine while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the
engine running for a minimum of 2 - 3
minutes before shutting it off. Starting and
stopping the engine over a short period of
time may make the vehicle more difficult to
start.
When racing the engine up to 4,000 rpm or
more under the no load condition, the en-
gine will enter the fuel cut mode.

5. To stop the engine, shift the selector leverto the P (Park) position and push the
ignition switch to the OFF position.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 tempera-
ture 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 operate).
Engine power and, under some conditions, ve-
hicle 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 downshift or up-
shift as it reaches prescribed shift points. You
can also shift manually.
As driving conditions change and engine cool-
ant temperature is reduced, vehicle speed can
be increased using the accelerator pedal, and
air conditioning cooling function will automati-
cally 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 tem-
perature 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 con-
tinue to drive and 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 by an INFINITI retailer.
See “WARNING/INDICATOR LIGHTS AND AU-
DIBLE REMINDERS” in the “2. Instruments and
controls” section.
DRIVING THE VEHICLE
5-14Starting and driving

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” in the “6. In case of
emergency” section.
CAUTION
Running the engine with the engine oil pres-
sure warning light on could cause serious dam-
age to the engine almost immediately. Such
damage is not covered by warranty. Turn off the
engine as soon as it is safe to do so.
AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
After starting the engine, fully depress the foot
brake pedal and push the selector lever button
before shifting the selector lever to the R (Re-
verse), N (Neutral), D (Drive) or Manual shift
mode position. Be sure the vehicle is fully
stopped before attempting to shift the selector
lever.
This automatic transmission model is designed
so that the foot brake pedal must be depressed
before shifting from P (Park) to any drive posi-
tion while the ignition switch position is ON.
The selector lever cannot be moved out of the P
(Park) position and into any of the other gear
positions if the ignition switch is pushed to the
LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed and
push the selector lever button to shift into
a driving gear. 2. Release the parking brake and foot brake,
then gradually start the vehicle in motion.
WARNING
●Do not depress the accelerator pedal while
shifting from P (Park) or N (Neutral) to R (Re-
verse), D (Drive) or manual shift mode. Al-
ways depress the brake pedal until shifting
is completed. Failure to do so could cause
you to lose control and have an accident.
● Cold engine idle speed is high, so use cau-
tion when shifting into a forward or reverse
gear before the engine has warmed up.
● Never shift to P (Park) or R (Reverse) while
vehicle is moving forward. Never shift to P
(Park), D (Drive) or manual shift mode while
vehicle is moving rearward. Failure to do so
could cause you to lose control and have an
accident.
● Except in an emergency, do not shift to the N
(Neutral) position while driving. Doing so
can cause a loss of engine braking which
may result in a collision, serious personal
injury or death. In addition, coasting with
the transmission in the N (Neutral) position
may cause serious damage to the
transmission.
Starting and driving5-15

The 4WD shift switch is used to select the 4WD
mode depending on the driving conditions.
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 stationary and the
selector lever in the N (Neutral) position when
changing into or out of 4L.
WARNING
●When parking, apply the parking brake be-
fore stopping the engine and make sure that
the 4WD shift indicator is on and the ATP
warning light turns off. Otherwise, the ve-
hicle could unexpectedly move even if the
automatic transmission is in the P (Park)
position.
● The 4LO and 4HI indicators must stop blink-
ing and the 4LO or 4HI indicator must remain
illuminated or turn off before shifting the
transmission into gear. If the selector lever
is shifted from the N (Neutral) position to any
other gear while the 4LO and 4HI indicators
are blinking alternately, the vehicle may
move unexpectedly.
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 in-
creased 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 trac-
tion. Avoid raising vehicle speed exces-
sively, as the maximum speed is approxi-
mately 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 reversing.
● Do not shift the 4WD shift switch (between
AUTO and 4H) while driving on steep down-
hill grades. Use the engine brake and low
automatic transmission gears for engine
braking.
● Do not operate the 4WD shift switch (be-
tween 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 sur-
faces 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 tem-
peratures 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 between 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 vehicle is stuck deep in mud, tire
chains may be effective.
Starting and driving5-87

●Never shift the 4WD shift switch between 4L
and 4H while driving.
● Engine idling speed is high while warming
up the engine. Be especially careful when
starting or driving on slippery surfaces with
the 4WD shift switch in AUTO.
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 selected by
the 4WD shift switch. (See the 4WD shift proce-
dure list shown in the “INFINITI ALL-MODE
4WD SYSTEM” earlier in this section.) ●
The 4WD shift indicator may blink while shift-
ing from one drive mode to the other. When
the shifting is completed, the 4WD shift indi-
cator will come on. If the indicator does not
come on immediately, make sure the area
around the vehicle is safe, and drive the ve-
hicle straight, accelerate or decelerate 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.

Starting and driving5-89

The 4WD warning light comes on when the
ignition switch is placed in the ON position. It
turns off soon after the engine is started.
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 warn-
ing 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 stop-
ping the vehicle for a while, have your ve-
hicle checked by an INFINITI retailer as soon
as possible.
● Shifting between 4HI and 4LO is not recom-
mended 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 in-
creased fuel consumption.
If the 4WD warning light turns on when driv-
ing 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 selector 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
●Incorrect wheel nuts or improperly tightened
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 tightened to speci-
fication at all times. It is recommended that
wheel nuts be tightened to specifications at
each lubrication interval. ●
Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for three
hours or more or driven less than 1 mile (1.6
km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to the
driver side center pillar.
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is be-
cause the tire pressurizes as the tire tempera-
ture rises. This does not indicate a system
malfunction.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
4. Close the lift gate.
WARNING
Always make sure that the spare tire and jack-
ing equipment are properly secured after use.
Such items can become dangerous projectiles
in an accident or sudden stop.
