CAUTION
Do not continue driving if the alternator belt is
loose, broken or missing.
Distance Control Assist (DCA)
system warning light
(orange; if so equipped)
This light comes on if there is a malfunction in
the Distance Control Assist (DCA) system.
If the warning light illuminates, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and turn on the DCA
system again.
If it is not possible to turn on the system or the
warning light stays on, it may indicate that the
system is malfunctioning. Although the vehicle
is still driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engineimmediately and call an INFINITI retailer
or other authorized repair shop. The engine oil pressure warning light is not de-
signed to indicate a low oil level. Use the dip-
stick to check the oil level.
(See “ENGINE OIL” in
the “8. Maintenance and do-it-yourself” sec-
tion.)
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.
Intelligent Cruise Control
(ICC) system warning light
(orange; if so equipped)
This light comes on if there is a malfunction in
the Intelligent Cruise Control (ICC) system.
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, resume driving and set the ICC system
again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the sys-
tem is malfunctioning. Although the vehicle is
still driveable under normal conditions, have the
vehicle checked at an INFINITI retailer.
Intelligent Key warning
light
After the ignition switch is pushed to the ON
position, this light comes on for about 2 sec-
onds and then turns off.
This light warns of a malfunction with the
electrical steering lock system (if so equipped)
or the Intelligent Key system.
If the light comes on while the engine is
stopped, it may be impossible to free the
steering lock (if so equipped) or to start the
engine. If the light comes on while the engine is
running, you can drive the vehicle. However in
these cases, contact an INFINITI retailer for
repair as soon as possible.
Lane departure warning light
(orange; if so equipped)
When the ignition switch is pushed to the ON
position, the light will come on in orange, turn
green, and then turn off. This indicates that the
Lane Departure Warning (LDW) and Lane Depar-
ture Prevention (LDP) systems are operational.
While the LDW and/or LDP system is on, the
light will blink in orange and a warning chime
will sound if the vehicle is traveling close to
either the left or the right of a traveling lane
with detectable lane markers.
2-14Instruments and controls

The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.If any malfunction occurs in the AWD system
while the engine is running, the warning light
will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high power train oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
If the warning light is blinking after the above
operation, have your vehicle checked by an
INFINITI retailer as soon as possible.
WARNING
●
For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
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
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
CAUTION
● Do not operate the engine on a free roller
when any of the wheels are raised.

ALL-WHEEL DRIVE (AWD) (if so equipped)
5-74Starting and driving

4. Lower the vehicle slowly until the tiretouches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
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:
80 ft-lb (108 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.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the luggage floor board.
3. Close the lift gate.
WARNING
● Always make sure that the spare tire and
jacking equipment are properly secured af-
ter use. Such items can become dangerous
projectiles in an accident or sudden stop.
● The T-type spare tire and small size spare
tire are designed for emergency use. See
specific instructions under the heading
“WHEELS AND TIRES” in the “8. Maintenance
and do-it-yourself” section.

REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the paint surface to avoid lasting damage or
staining. Special cleaning products are avail-
able 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 windows, do
not use sharp-edged tools, abrasive cleaners or
chlorine-based disinfectant cleaners. They
could damage the electrical conductors, radio
antenna elements or rear window defroster
elements.
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 remove the
cleaner within 15 minutes after the cleaner is
applied.
CHROME PARTS
Clean chrome parts regularly with a non- abra-
sive chrome polish to maintain the finish.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
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 selector lever to P (Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition 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 whenever 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 sup-
ported 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 warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer because the fuel lines are under high
pressure even when the engine is off.
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 engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.

of coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the INFINITI Service and Main-
tenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●To avoid the danger of being scalded, never
change the coolant when the engine is hot.
●
Never remove the radiator cap when the engine
is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.
●Avoid direct skin contact with used coolant. If
skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
● Keep coolant out of reach of children and
pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill

6. Recheck oil level with the dipstick.
It is normal to add some oil between oil mainte-
nance intervals or during the break-in period,
depending on the severity of operating condi-
tions.
CAUTION
Oil level should be checked regularly. Operat-
ing the engine with an insufficient amount of oil
can damage the engine, and such damage is
not covered by warranty.
