∙When the INFINITI InTouch™ system
malfunctions or does not operate nor-
mally.
∙ While driving (the vehicle is not
stopped). 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 acceler-
ating 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 cor-
rectly.
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.

When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring 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 fea-
ture 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 controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ∙ Do not modify the vehicle’s suspension. If
suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the VDC system may not
operate properly. This could adversely
affect vehicle handling performance, and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and
the
indicator lights may illuminate.
∙ If engine control related parts are not INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate. ∙ When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator may flash or both
the
andindicator lights may
illuminate. Do not drive on these types of
roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or ramp,
the
indicator may flash or both
the
andindicator lights may
illuminate. This is not a malfunction. Re-
start the engine after driving onto a
stable surface.
∙ If wheels or tires other than the INFINITI recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or both
the
andindicator lights may
illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow cov-
ered road.

BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of force
to each of the four wheels depending on the
radius of the turn.
WARNING
∙ The VDC system is designed to help thedriver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
∙ Do not modify the vehicle’s suspension. If suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the VDC system may not
operate properly. This could adversely
affect vehicle handling performance, and

ommended or are extremely deterio-
rated, the VDC system may not operate

Engine coolant*:Replace coolant at the
specified interval. When adding or replacing
coolant, be sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent with the proper mixture. (For ad-
ditional information on the proper mixture for
your area, refer to “Engine cooling system” in
the “Do-it-yourself” section of this manual.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter: Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity refer to
“Recommended fluids/lubricants and capaci-
ties” in the “Technical and consumer informa-
tion” section of this manual.
Engine valve clearance*: Inspect only if valve
noise increases. Adjust valve clearance if nec-
essary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as nec-
essary. Fuel lines*:
Check the fuel hoses, piping and
connections for leaks, looseness, or deterio-
ration. Tighten connections or replace parts
as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace
any deteriorated or damaged parts immedi-
ately.
Brake pads and rotors: Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks,
deterioration, and damage. Tighten connec-
tions or replace parts as necessary.
In-cabin microfilter: Replace at specified in-
tervals. When driving for prolonged periods in
dusty conditions, replace the filter more fre-
quently. Propeller shaft(s):
Check for damage, loose-
ness, and grease leakage. (AWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots: Check for dam-
age, looseness, and leakage of oil or grease.
Under severe driving conditions, inspect more
frequently.
Tire rotation: Tires should be rotated every
7,500 miles (12,000 km) according to the
instructions under “Explanation of general
maintenance items” in this section. When ro-
tating tires, check for damage and uneven
wear. Replace if necessary.
Transmission fluid/oil, differential oil and
transfer case oil: Visually inspect for signs of
leakage at specified intervals.
Replace at specified intervals.

NOTE:
Maintenance items with “” should be performed more frequently according to “Maintenance under severe driving conditions”.
(1) If using a car-top carrier or driving on rough or muddy roads, inspect CVT fluid deterioration every 60,000 miles (96,000 km), then change
CVT fluid if necessary. And if the inspection is not performed, change (not just inspect) CVT fluid every 60,000 miles (96,000 km). It is
recommended that you visit an INFINITI retailer for this service.
(2) If using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000 km) or 24 months.
(3) For additional information on tire rotation, refer to “General maintenance” in this section.
