conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under the following conditions:
—On roads where the traffic is heavyor there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
When the windshield wiper is oper-
ated at the high speed (HI) position,
the Intelligent Cruise Control system
is automatically canceled. If the
vehicle is equipped with a rain
sensing auto wiper, the system may
cancel when the wipers are set to the
AUTO position.
—When strong light (for example, at
sunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. 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 distance from other vehicles
using the accelerator 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
Y51D-V-E01-C712CA46-F1DA-4C8D-AA1F-94E1C58C147FAlways 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 vehicles (following dis-
tance) 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

5-72Starting and driving
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
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
following 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
distance control function, never rely
solely on the Distance Control Assist
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing 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
conditions. To avoid accidents, never use
the Distance Control Assist system
under the following 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, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequentbraking may result in overheating
the brakes)
—On repeated uphill and downhill
roads
. 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 distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.

BRAKING PRECAUTIONSY51D-V-E01-306DF583-15A7-4F2E-A62C-BF5322FC38D7The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakesY51D-V-E01-78C52DD3-F84F-4DBD-A69F-5E2253E57FCEThe brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure 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 brakesY51D-V-E01-4164933E-9063-4069-9B0B-00C0D135CBA1When 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 thevehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-INY51D-V-E01-8D2FFD7C-4467-45F7-A514-CBBDEBD1F7FBBreak in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened 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
service manual and can be performed by
an INFINITI retailer.
Using the brakesY51D-V-E01-CBE6144D-573B-4C4C-8A27-7992EBD125D3Avoid 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.
WARNING
.
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
. If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.

Y51D-V-E01-9ECDEC9C-D91E-43BE-8956-65EFDD4A98EF
CAUTION
.Do not continue to drive if your vehicle
overheats. 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, possibly 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
shift 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
conditioner temperature control to
maximum hot and fan control to high speed.
3. If engine overheating is caused by
climbing 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.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood
further until no steam or coolant can be
seen.
5. Open the engine hood.WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking or the cooling fan does
not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
7. After the engine cools down, check thecoolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer.
