Initialize entry/exit function If the battery cable is disconnected, or if the
fuse opens, the entry/exit function will not work
though this function was set on before. In such
a case, after connecting the battery or replacing
with a new fuse, open and close the driver’s
door more than two times after the ignition
switch is turned from the ON position to the
LOCK position. The entry/exit function will be
activated.
SEAT SYNCHRONIZATION FUNCTION The seat synchronization function automatically
adjusts the positions of the steering wheel and
outside mirrors when the seat is adjusted using
the power seat switches.
However, the steering wheel and outside mir-
rors will not move if the seat is adjusted over
the maximum thresholds. The system considers
that the steering wheel and outside mirror
adjustments are not necessary because the
seat may not be adjusted for the driving posi-
tion. Note that the function is set to disabled as
the factory default setting. The seat synchronization function operates un-
der the following conditions:
● The ignition switch is in the ON position.
● The selector lever is in the P (Park) position
(Automatic Transmission models) or the
parking brake is applied (Manual Transmis-
sion models).
● The seatback is raised (Coupe).
If the outside mirrors or the steering wheel
reaches its maximum adjustment, the function
is automatically disabled. Restart the function
by selecting a previously stored seat memory
position using the memory switches (1 or 2). An
Intelligent Key that was previously linked to the
stored seat memory can also be used to restart
the function.
If a seat position was not previously stored in
the seat memory, restart the function by adjust-
ing the steering wheel and outside mirrors
manually for your best driving position and then
drive the vehicle above 4 MPH (7 km/h). SPA2322

SONAR SYSTEM OFF SWITCH The sonar system OFF switch on the instrument
panel allows the driver to turn the sonar system
on and off. To turn the sonar system on and off,
the ignition switch must be in the “ON” posi-
tion. The indicator light
 1
on the switch will
illuminate when the system is turned off. If the
indicator light flashes when the sonar system is
not turned off, it may indicate a malfunction in
the sonar system. WARNINGIf 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.
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.SSD0929

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.
● Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
● Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:
– understeer (vehicle tends to not follow
the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the
indicator in the instrument panel flashes so
note the following: ● The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
See “Slip indicator light” in the “2. Instruments
and controls” section and “Vehicle Dynamic
Control (VDC) off indicator light” in the “2.
Instruments and controls” section.
If a malfunction occurs in the system, the
and indicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator illuminates to
indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The indicator
flashes if this occurs. All other VDC functions
are off and the indicator will not flash.
The VDC System is automatically reset to on when the ignition switch is placed in the off
position then back to the on position.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunc-
tion.
WARNING● The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driving
and cornering on slippery surfaces and al-
ways drive carefully.

If the battery is disconnected or discharged,
the steering wheel will lock and cannot be
turned. Supply power using jumper cables
before pushing the ignition switch and dis-
engaging the steering lock.
CAUTION● Always connect positive (+) to positive (+)
and negative (  ) to body ground (as illus-
trated) — not to the battery.
● Make sure the jumper cables do not touch
moving parts in the engine compartment and
that clamps do not contact any other metal.
5. Start the engine of the booster vehicle
 A
and let it run for a few minutes.
6. Keep the engine speed of the booster
vehicle
 A
at about 2,000 rpm, and start
the engine of the vehicle being jump
started

).
8. Replace the vent caps (if so equipped). Be
sure 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.

restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level. Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI retailer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from
the air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes are
evident, check for the cause and have it cor-
rected immediately. Power steering fluid level* and lines: Check the
level when the fluid is cold, with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
