– During bad weather (rain, fog, snow, etc.)When the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking may result in overheating
the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it difficult to keep a proper distance between vehicles
because of frequent acceleration or
deceleration
● Do not use the Intelligent Cruise Control sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead. ●
In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The vehicle-to-
vehicle distance control mode of the Intelligent
Cruise Control (ICC) system may not be able to
maintain the selected distance between ve-
hicles (following distance) or selected vehicle
speed under some circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated on the front of the
vehicle to detect vehicles traveling ahead. The
sensor generally detects the signals returned
from the reflectors on a vehicle ahead. There-

WARNING
●This system is only an aid to assist the driver
and is not a collision warning or avoidance
device. It is the driver’s responsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
● This system will not adapt automatically to
road conditions. Do not use the system on
roads with sharp curves, or on icy roads, in
heavy rain or in fog.
The distance sensor will not detect the follow-
ing objects:
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel
lane
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Distance Control Assist system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. To avoid accidents, never use the Dis-
tance Control Assist system under the fol-
lowing conditions:
– On roads with sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor – On steep downhill roads (frequent brak-
ing may result in overheating the brakes)
– On repeated uphill and downhill roads
● Do not use the Distance Control Assist sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead.
● In some road or traffic conditions, a vehicle
or object can unexpectedly come into the
sensor detection zone and cause automatic
braking. You may need to control the dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the DCA system when it is not recommended
in this section.
Starting and driving5-55

WARNING
If the engine is not running or is turned off while
driving, the power assist for the steering will
not work. Steering will be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.

8. Replace the vent caps (if so equipped). Besure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
9. Put the battery cover on.Do not attempt to start the engine by pushing.
CAUTION
● Automatic transmission models cannot be
push-started or tow-started. Attempting to
do so may cause transmission damage.
● Three way catalyst equipped models should
not be started by pushing since the three
way catalyst may be damaged.
● Never try to start the vehicle by towing it;
when the engine starts, the forward surge
could cause the vehicle to collide with the
tow vehicle.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty Information
Booklet (Canada).
CAUTION
● Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position.
Do not stop the engine.2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb- ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.

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
3.
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.
CHANGING ENGINE OIL AND FILTER
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn the engine off and wait more than 15 minutes.
4. Raise and support the vehicle using a suitable floor jack and safety jack stands.
●Place the safety jack stands under the
vehicle jack-up points.
● A suitable adapter should be attached to
the jack stand saddle.

E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed onlevel roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. ●
U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.
