GUID-8D71F741-560B-4B4E-AA55-F9F223C96E4FThe selector lever must be in the P (Park)
position with the ignition switch in the OFF
position.
The entry/exit function can be activated or
canceled by pressing and holding the SET
switch for more than 10 seconds.
The indicator lights on the memory
switches (1 and 2) will blink once when
the function is canceled, and the indicator
lights will blink twice when the function is
activated. Note that the indicator lights
may illuminate after 5 seconds while
holding the SET switch. This indicates
readiness for linking the Intelligent Key to
a stored memory position. Keep the SET
switch pressed for more than 10 seconds
to turn on or off the entry/exit function.
The entry/exit function can also be acti-
vated or canceled if the “Lift Steering
Wheel on Exit” key or“Slide Driver Seat Back on Exit”
key is turned to ON or OFF in
the “Comfort” settings. (See “Vehicle
information and settings” (P.4-9).)
Initialize entry/exit functionGUID-0EEBBCEC-2899-4DC8-AE43-1CC42FE3C5C1If 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 FUNCTIONGUID-44A9BCE7-C5A3-4DE5-84C7-DAFAF434BFA8The seat synchronization function automa-
tically 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
mirrors 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 neces-
sary because the seat may not be adjusted
for the driving position. Note that the
function is set to disabled as the factory
default setting.

SONAR SYSTEM OFF SWITCHGUID-446340A3-E5C0-4566-9701-88DF98FE3774The 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”position. The
indicator light
*1on 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.
GUID-7A26DC9E-F480-487F-A4C2-174FF498CC5C
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 PRECAUTIONSGUID-69469B45-E0A5-4BC3-B99F-C3213CC27874The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakesGUID-95686AE6-7A34-4D3E-9305-085085C76F84The 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 brakesGUID-B2433212-C5E2-4B61-9394-8ED34BB6A681When 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

5-58Starting and driving
Normal operationGUID-36C3BA08-72B5-4E9B-96CF-93CCD7FE6655The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic
pressure. This action is similar to pumping
the brakes very quickly. You may feel a
pulsation in the brake pedal and hear a
noise from under the hood or feel a
vibration from the actuator when it is
operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
GUID-B2222C83-77D9-46CF-971F-591ADE2397C3The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, 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 func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
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 VDC
warning light
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 “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
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 VDC warning light
flashes if
this occurs. All other VDC functions are off,
and the VDC warning light
will not
flash. The VDC system is automatically

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 the
coolant 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.
GUID-EFD3ED0D-F0D8-4E16-A86F-75D73E7484FAWhen towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an
INFINITI retailer. Local service operators are
familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, INFINITI recommends that
you have a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions.
WARNING
. Never ride in a vehicle that is being
towed.
. Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
.When towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any unit is damaged, dollies must be

securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head 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
steering 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
properly.
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 vehicleGUID-29B64B94-E77F-40DC-A4B2-6B5D542860EDThe 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 tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
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, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) 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 corrected 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.
