2010 INFINITI M engine

WARNING
cFor AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
c Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed on a
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
Your vehicle is equipped with full-time All-
Wheel Drive (AWD).
Switching the driving mode is not necessary. The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.If any malfunction occurs in the AWD system
while the engine is running, the warning light
will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high powertrain oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light turns
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
CAUTION
c
If the warning light remains on after the
above operation, have your vehicle checked
by an INFINITI retailer as soon as possible.
c If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.

cThe powertrain may be damaged if you con-
tinue driving with the warning light blinking
rapidly.
WARNING
cDo not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
c Never leave the engine running while the
vehicle is unattended.
c Do not leave children unattended inside the
vehicle. They could unknowingly activate
switches or controls. Unattended children
could become involved in serious accidents. c
Safe parking procedures require that both
the parking brake be applied and the trans-
mission placed into P (Park). Failure to do so
could cause the vehicle to move unexpect-
edly or roll away and result in an accident.
c Make sure the automatic transmission se-
lector lever has been pushed as far forward
as it can go and cannot be moved without
depressing the foot brake pedal.
1. Firmly apply the parking brake.
2. Move the selector lever to the P (Park)
position.

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.

Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and 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
cWhile driving on a slippery surface, be care-
ful when braking, accelerating or downshift-
ing. Abrupt braking or accelerating could
cause the wheels to skid and result in an
accident.
c 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.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force than
a conventional brake booster even with light
pedal force.
WARNING
The Brake Assist is only an aid to assist braking
operation and is not a collision warning or
avoidance device. It is the driver's responsibil-
ity to stay alert, drive safely and be in control of
the vehicle at all times.
PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system equipped
models)
When the Preview Function identifies the need
to apply emergency braking by sensing a ve-
hicle ahead in the same lane and the distance
and relative speed from it, it applies the brake
pre-pressure before the driver depresses the
brake pedal and helps improve brake response
by reducing pedal free play.
c This system will not operate when the ve-
hicle is moving at approximately 20 MPH
(32 km/h) or less.

cWhen the Preview Function operates, the
brake pedal may move slightly and may
make a small noise. This is not a system
malfunction.
Warning light and display
When the Preview Function is not operating
properly, the buzzer sounds and the system
warning light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine and resume driving.
If the indicator stays on, it may indicate that the
Preview Function is malfunctioning (the brake is
operative). Although the Vehicle is still drive-
able under normal conditions, have the vehicle
checked at an INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating prop-
erly, be sure to observe the following:
c Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
c Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so could
cause failure or malfunction. If the sensor is
damaged due to an accident, contact an
INFINITI retailer.
c Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.

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.

Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h). The speed varies according to
road conditions.
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. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the brak-
ing and engine output to help improve vehicle
stability.
c
When the VDC system is operating, the
ªSLIPº indicator in the instrument panel
blinks.
c If the ªSLIPº indicator blinks, the road con-
ditions are slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. (See ªSlip indicator
lightº in the ª2. Instruments and controlsº
section, and ªVehicle Dynamic Control (VDC)
off indicator lightº in the ª2. Instruments
and controlsº section.)
c Indicator light
If a malfunction occurs in the system, the
ªSLIPº and ªVDC OFFº indicator lights illumi-
nate in the instrument panel. As long as
these indicators are illuminated, the VDC
system function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other drive wheel. If the vehicle is operated with the VDC
OFF switch pushed and the VDC system turned
off, all VDC systems will be turned off. The ABLS
system and ABS will still operate with the VDC
system off. If the ABLS system is activated, the
ªSLIPº indicator will blink and 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 malfunction.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise
or feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system computer has a built-in diag-
nostic feature that tests the system each time
you start the engine and move the vehicle at a
low speed forward or backward. When the
self-test occurs, you may hear a ªclunkº noise
and/or feel a pulsation in the brake pedal. This
is normal and is not an indication of a
malfunction.

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.
