power steering INFINITI M 2011 User Guide

When the VDC OFF switch is used to turn off the
VDC system, the active trace control system is
also turned off.
If the active trace control is not functioning
properly, the IBA OFF indicator light illuminates
in the instrument panel.
RISE-UP AND BUILD-UP
The system gradually adjusts braking power
during normal braking to help provide an en-
hanced brake feel.
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 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. ●
The active trace control (if so equipped),
rise-up and build-up and brake force distri-
bution systems may not be effective depend-
ing on the driving condition. Always drive
carefully and attentively.
● Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate prop-
erly. This could adversely affect vehicle han-
dling performance, and the VDC warning
light
may illuminate.
● If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate. ●
When driving on extremely inclined surfaces
such as higher banked corners, the VDC sys-
tem may not operate properly and the VDC
warning light
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 VDC
warning light
may illuminate. This is
not a malfunction. Restart the engine after
driving onto a stable surface.
● If wheels or tires other than the INFINITI rec-
ommended ones are used, the VDC system
may not operate properly and the VDC warn-
ing light
may illuminate.
● The VDC system is not a substitute for winter
tires or tire chains on a snow covered road.

When towing your vehicle, all State (Provincial
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 appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends that
you have a service operator tow your vehicle. It
is advisable to have the service operator care-
fully read the following precautions.
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 transmis-
sion, axles, steering system and powertrain
are in working condition. If any unit is dam-
aged, dollies must be used.
● Always attach safety chains before towing. For information about towing your vehicle be-
hind a recreational vehicle (RV), see “FLAT
TOWING” in the “9. Technical and consumer
information” section of this manual.

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.

●Prolonged and repeated contact with used
engine oil may cause skin cancer.
● Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep used engine oil out of reach of children. When checking or replacement is required, we
recommend an INFINITI retailer for servicing.
CAUTION
●
Use only Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
● Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will cause
deterioration in driveability and automatic
transmission durability, and may damage
the automatic transmission, which is not
covered by the INFINITI new vehicle limited
warranty. Check the fluid level in the reservoir.
The fluid level should be checked using the HOT
range (
1: HOT MAX.,2: HOT MIN.) at fluid
temperatures of 122 to 176°F (50 to 80°C) or
using the COLD range (
3: COLD MAX.,4:
COLD MIN.) at fluid temperatures of 32 to 86°F
(0 to 30°C).
If the fluid is below the MIN line, add Genuine
NISSAN PSF or equivalent. Remove the cap and
fill through the opening.
CAUTION
● Do not overfill.
● Use Genuine NISSAN PSF or equivalent.

CAUTION
●Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.
