WARNING LIGHTS
orAnti-lock Braking
System (ABS) warning light
When the ignition switch is in the ON
position, the Anti-lock Braking System
(ABS) warning light illuminates and then
turns off. This indicates the ABS is opera-
tional.
If the ABS warning light illuminates while the
engine is running, or while driving, it may
indicate the ABS is not functioning properly.
Have the system checked. It is recommended
you visit an INFINITI retailer for this service.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then
operates normally, but without anti-lock
assistance. (See “Brake system” (P.5-122).)
Automatic transmission check

the light flickers or comes on 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 engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level. (See “Engine
oil” (P.8-6).)
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.
Four-Wheel Drive (4WD)
warning light (4WD models)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the 4WD system malfunctions, or the diameter of the front and the rear wheels are
different, the warning light will either remain
illuminated or blink. (See “INFINITI all-mode

®” (P.5-111).)
CAUTION
.
If the warning light comes on while
driving there may be a malfunction in
the 4WD system. Reduce the vehicle
speed and have your vehicle checked
as soon as possible. It is recom-
mended you visit an INFINITI retailer
for this service.
. If the 4WD warning light turns on
when driving on dry or hard surfaced
roads:
— in the 4H(I) position, shift the 4WD shift switch to AUTO
— in the 4L(O) 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 warning light is still on after the
above operations, have your vehicle
checked as soon as possible. It is
recommended you visit an INFINITI
retailer for this service.
Forward Emergency Braking
(FEB) system warning light
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the engine is started.
This light illuminates when the Forward
Emergency Braking (FEB) with pedestrian
detection system is set to OFF on the lower
display.
If the light illuminates when the FEB with
pedestrian detection system is ON, it may
indicate that the system is unavailable. See
“Forward Emergency Braking (FEB) with
pedestrian detection” (P.5-93) for more de-
tails.
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors
the tire pressure of all tires except the spare.

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.
Starting and driving5-17
DRIVING THE VEHICLE
Page 365 of 516
.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion 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 a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD before it
is placed on a dynamometer. Using
the wrong test equipment may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
CAUTION
.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 Four-Wheel Drive (4WD)
warning light turns on when driving
on dry hard surface roads:
— in the 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
lever to the N (Neutral) position
with the brake pedal depressed
and shift the 4WD shift switch to
AUTO.
If the 4WD warning light is still on
after the above operation, have
your vehicle checked. It is recom-
mended you visit an INFINITI
retailer for this service.
. The transfer case may be damaged if
you continue driving with the 4WD
warning light blinking.
See “On-pavement and off-road driving
precautions” (P.5-8) for other precautions
for offroad driving.

INCREASING FUEL ECONOMYINFINITI ALL-MODE 4WD®(if so equipped)
Page 369 of 516
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.

5-118Starting 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 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.

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving parts.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off. It is recommended you visit an
INFINITI retailer for this service.
CAUTION
.
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-34).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
