WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
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.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather conditions. To avoid accidents, never use
the Intelligent Cruise Control system
under the following conditions:
—On roads where the traffic is heavy
or 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 low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere to
the 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.
Starting and driving5-39

5-60Starting 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.

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 hy-
draulic 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, especially in sharp turns and at
low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hy-
draulic 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. 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 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 sideduring 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
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 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

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. Attempt-
ing 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.
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
