steering INFINITI M 2010 Repair Manual

3. To help prevent the vehicle from rollinginto the street when parked on a sloping
drive way, it is a good practice to turn the
wheels as illustrated.
cHEADED DOWNHILL WITH CURB:s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
c HEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
c HEADED UPHILL OR DOWNHILL, NO CURB:
s3
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. Push the ignition switch to the LOCK
position.
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 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.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
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.
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.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
cThe Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal surfaces even with ABS. Stopping dis-
tances may also be longer on rough, gravel
or snow covered roads, or if you are using
tire chains. Always maintain a safe distance
from the vehicle in front of you. Ultimately,
the driver is responsible for safety.
c Tire type and condition may also affect brak-
ing effectiveness.
± When replacing tires, install the specified size of tires on all four wheels.
± When installing a spare tire, make sure that it is the proper size and type as speci-
fied on the Tire and Loading Information
label. See ªTIRE AND LOADING INFORMA-
TION LABELº in the ª9. Technical and con-
sumer informationº section of this
manual. ± For detailed information, see ªWHEELS
AND TIRESº in the ª8. Maintenance and
do-it-yourselfº section of this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ªclunkº noise and/or feel a
pulsation in the brake pedal. This is normal and
does not indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.

WARNING
cThe VDC system is designed to help improve
driving stability but does not prevent acci-
dents due to abrupt steering operation at
high speeds or due to careless or dangerous
driving techniques. Reduce vehicle speed
and be especially careful when driving and
cornering on slippery surfaces and always
drive carefully.
c Do not modify the vehicle's suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars and bushings
and wheels are not INFINITI approved or are
extremely deteriorated the VDC system may
not operate properly. This could adversely
affect vehicle handling performance, and the
ªVDC OFFº indicator or ªSLIPº indicator or
both indicator lights may illuminate.
c If brake related parts such as brake pads,
rotors and calipers are not standard equip-
ment or are extremely deteriorated, the
ªVDC OFFº indicator or ªSLIPº indicator or
both indicator lights may illuminate.
c If engine related parts such as muffler are
not standard equipment or are extremely de-
teriorated, the ªVDC OFFº indicator or ªSLIPº
indicator or both indicator lights may
illuminate. c
When driving on extremely inclined surfaces
such as higher banked corners, the VDC sys-
tem may not operate properly and the ªVDC
OFFº indicator or ªSLIPº indicator or both
indicator lights may illuminate. Do not drive
on these types of roads.
c When driving on unstable surfaces such as a
turntable, ferry, elevator or ramp, the ªVDC
OFFº indicator or ªSLIPº indicator or both
indicator lights may illuminate. This is not a
malfunction. Restart the engine after driving
onto a stable surface.
c If wheels or tires other than those recom-
mended are used, the VDC system may not
operate properly and ªVDC OFFº indicator or
ªSLIPº indicator or both indicator lights may
illuminate.
c The VDC system is not a substitute for winter
tires or tire chains on a snow covered road. The Rear Active Steer system is an electronically
controlled four-wheel steering system.
The angle of the rear wheels are adjusted by the
Rear Active Steer system, depending on the
vehicle speed and steering angle. The rear
wheels are designed to turn momentarily in the
opposite direction and then change to the same
direction as the front wheels.
At low speeds, the rear wheels will not turn and
the system functions as a two-wheel steering
system.
If a malfunction occurs in the system, the Rear
Active Steer function will stop but the ordinary
two-wheel steering system will operate nor-
mally. The ªRASº warning light will illuminate. If
the light illuminates while driving, contact an
INFINITI retailer for repair.
WARNING
The Rear Active Steer system, although a so-
phisticated device, cannot prevent accidents
resulting from careless or dangerous driving
techniques. Ultimately the responsibility for
safety of self and others rests in the hands of
the driver. Therefore only through attentive
and careful driving methods can the Rear Active
Steer system be fully appreciated and safety
assured.

Every new INFINITI comes with a 4 year, unlim-
ited mileage Roadside Assistance plan. In the
event of a roadside emergency, Roadside Assis-
tance Service is available to you. Please refer to
your Warranty Information Booklet (U.S.) or
Warranty & Roadside Assistance Information
Booklet (Canada) for details. Both the Warranty
Information Booklet and Roadside Assistance
Calling Card in your Owner's Literature Portfolio
provide the Toll-Free Number to call for assis-
tance. Roadside Assistance is provided 24
hours a day, 365 days a year, for 4 years from
the date sold to give emergency roadside help,
in the event of mechanical or nonmechanical
trouble(s) such as flat tires, out-of-gas, dead
battery, lost keys, mechanical breakdown, acci-
dent, etc.TIRE PRESSURE MONITORING SYSTEM
(TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires except the spare. When the
low tire pressure warning light is lit, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and warn
you of it by the low tire pressure warning light
(in the instrument panel) or the LOW PRESSURE
information screen (on the display). This system
will activate only when the vehicle is driven at
speeds above 16 MPH (25 km/h). For more
details, see ªWARNING/INDICATOR LIGHTS AND
AUDIBLE REMINDERSº in the ª2. Instruments
and controlsº section and ªTIRE PRESSURE
MONITORING SYSTEM (TPMS)º in the ª5. Start-
ing and drivingº section.
For information about the tire pressure informa-
tion display, see ªHOW TO USE INFO BUTTONº
in the ª4. Monitor, climate, audio, phone and
voice recognition systemsº section.
WARNING
cIf the low tire pressure warning light illumi-
nates or LOW PRESSURE information is dis-
played on the monitor screen while driving,
avoid sudden steering maneuvers or abrupt
braking, reduce vehicle speed, pull off the
road to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage the
tires and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur and
may lead to an accident and could result in
serious personal injury. Check the tire pres-
sure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure
shown on the Tire and Loading Information
label to turn the low tire pressure warning
light OFF. If the light still illuminates while
driving after adjusting the tire pressure, a
tire may be flat. If you have a flat tire, replace
it with a spare tire as soon as possible.
c When a spare tire is mounted or a wheel is
replaced, tire pressure will not be indicated,
the TPMS will not function and the low tire
pressure warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Contact your INFINITI retailer
as soon as possible for tire replacement
and/or system resetting.

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment. If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the
INFINITI Warranty Information Booklet.
Windshield:
Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal.
Automatic transmission P (Park) position
mechanism: On a fairly steep hill, check that the vehicle is held securely with the selector
lever in the P (Park) position without applying
any brakes.
Brake pedal:
Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI retailer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justment, see an INFINITI retailer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed 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.
