OPERATING TIPS
The sensors,OAandOBon the instrument
panel, help the system maintain a constant
temperature. Do not put anything on or
around these sensors. • When the engine coolant temperature and
outside air temperature are low, the air may
flow from defroster or foot outlets to ini-
tialize automatic heating mode. This is not a
malfunction. After the coolant temperature
warms up, air will flow normally from the
foot outlets
• A visible mist may be seen coming from the ventilators in hot, humid conditions as the
air is cooled rapidly. This does not indicate a
malfunction.

button to place the vehicle in the P (Park)
position and check that the electronic
parking brake indicator light is illumi-
nated to confirm that the electronic
parking brake is applied. The electronic
parking brake indicator light will remain
on for a period of time after the driver’s
door is locked.
CAUTION
When parking in an area where the outside
temperature is below 32°F (0°C), the park-
ing brake, if applied, may freeze in place
and may be difficult to release.
For safe parking, it is recommended that
you place the shift position in the P (Park)
position and securely block the wheels.
NOTE:
• If a malfunction occurs in the electronic parking brake system (for example, due to
battery discharge), it is recommended that
you visit an INFINITI retailer. • Under the following conditions the elec-
tronic parking brake will automatically be
applied and the braking force of the auto-
matic brake hold will be released:
– The braking force is applied by the auto- matic brake hold function for 3 minutes
or longer.
– The vehicle is in the P (Park) position.
– The electronic parking brake is applied manually.
– The driver’s seat belt is unfastened.
– The driver’s door is opened.
– The ignition switch is placed in the OFF position.
– A malfunction occurs in the automatic brake hold function.
MANUAL OPERATION

Starting and driving5-25

•This function is only activated with the
left turn signal and will briefly accelerate
the vehicle even if a lane change is not
initiated. This can include non-passing
situations such as left side exits.
• Ensure that when passing another ve-
hicle, the adjacent lane is clear before ini-
tiating the pass. Sudden changes in traf-
fic may occur while passing- always
manually steer or brake as needed- never
solely rely on the system.
ICC system limitations
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death:
• The ICC system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use the
ICC system in city traffic or congested
areas. •
The ICC system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing traffic.
Do not use the system on roads with
sharp curves or on icy roads, in heavy rain
or in fog.
• As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absentminded driving or overcome poor
visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by
depressing the brake pedal, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain a safe distance between
vehicles.
• When the ICC system automatically
brings the car to a stop, your vehicle can
automatically accelerate if the vehicle
is stopped for less than approximately
3 seconds. Be prepared to stop your ve-
hicle if necessary.
• Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main- tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circumstances.
• The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following con-
ditions:
– On roads with heavy, high-speed
traffic or sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
Starting and driving5-89

• HEADED UPHILL OR DOWNHILL,NO CURB
OC:
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Place the ignition switch in the LOCK position.ELECTRIC POWER STEERING
TYPE
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.
• When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged. While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will
return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.
For additional information, see “Power steer-
ing warning light” (P. 2-16).
POWER STEERING
Starting and driving5-137

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear 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.
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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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 rotors are replaced, in order to
assure the best brake performance.
This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
• The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is
responsible for safety.
BRAKE SYSTEM
5-140Starting and driving

CAUTION
• Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
• Do not push start this vehicle. The three-
way catalyst may be damaged.WARNING
• 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 coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized 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.
2. Push the park button to shift to the P (Park) position.
Do not stop the engine.
3. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radia-
tor 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 en-
gine, 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 coolant is leaking,
the water pump belt is missing or loose, 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.
