ESP INFINITI M 2011 Owner's Manual

The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle
ahead in the traveling lane and the driver must
take avoidance action immediately. The system
helps reduce the rear-end collision speed by
applying the brakes when the system judges
that the collision cannot be prevented.
The IBA system will function when your vehicle
is driven at speeds of approximately 10 MPH (15
km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH
(15 km/h) faster than the vehicle ahead.The IBA system uses a distance sensorA
located below the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the traveling lane, the vehicle
ahead detection indicator light on the instru-
ment panel blinks and a warning chime sounds.
The IBA system will be turned on/off by pushing
the IBA OFF switch. The IBA OFF indicator light
display will illuminate when the system is
turned off.
PRECAUTIONS ON IBA SYSTEM
WARNING
●
The IBA system is not a collision avoidance
system. It is the driver’s responsibility to
stay alert, drive safely and be in control of
the vehicle at all times.
● As there is a performance limit, the system
may not provide a warning or braking in cer-
tain conditions.
● The system will not detect the following
objects:
– Pedestrians, animals or obstacles in the roadway
– Oncoming vehicles in the same lane

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.
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.
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 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.
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.
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 save the brakes 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 care-
ful when braking, accelerating or downshift-
ing. Abrupt braking or accelerating 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.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 (Intelligent Cruise
Control 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.
● This system will not operate when the ve-
hicle is moving at approximately 20 MPH (32
km/h) or less. ●
The pre-pressure function ceases when the
following conditions are met:
a) When the driver depresses the accel- erator pedal or the brake pedal.
b) If the driver does not operate the ac- celerator or brake pedal within ap-
proximately 1 second.

travel lane as illustrated
WARNING
●This system is only an aid to assist braking
operation and is not a collision warning or
avoidance device. It is the driver’s responsi-
bility to stay alert, drive safely and be in
control of the vehicle at all times. ●
As there is a performance limit to the Pre-
view Function, never rely solely on this sys-
tem. This system does not correct careless
inattentive or absent-minded driving, or
overcome poor visibility in rain, fog, or other
bad weather. Reduce vehicle speed by de-
pressing the brake pedal, in order to main-
tain a safe distance between vehicles.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. The Preview Function may not operate
properly under the following conditions. The
vehicle is still driveable under normal condi-
tions and the Brake Assist will operate.
– When rain, snow or dirt adhere to the sys- tem sensor
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– Winding or hilly roads may cause the sen- sor to temporarily not detect a vehicle in
the same lane or may detect objects or
vehicles in other lanes.
– Vehicle position in the lane may cause the sensor to temporarily not detect a vehicle
in the same lane or may detect objects or
vehicles in other lanes. ●
When 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, a chime sounds and the system warn-
ing 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:
●Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
● 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.
● 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
● The 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.
● 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 “TIRE AND LOADING INFORMA-
TION LABEL” in the “9. Technical and con-
sumer information” section of this
manual.

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, 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 function).
● Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions).
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 warn-
ing 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) warning
light” in the “2. Instruments and controls”
section.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instru-
ment panel. The VDC system automatically
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, except for rise-up and
build-up and brake force distribution, and the
VDC warning light
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.
See “Vehicle Dynamic Control (VDC) warning
light” in the “2. Instruments and controls”
section and “Vehicle Dynamic Control (VDC) off
indicator light” in the “2. Instruments and con-
trols” section.
The computer has a built-in diagnostic feature
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.
ACTIVE TRACE CONTROL (if so
equipped)
This system senses driving based on the driv-
er’s steering and acceleration/braking patterns,
and controls brake pressure at individual
wheels and engine output to help smooth ve-
hicle response.
When the drive mode selector switch is set to
the “SPORT” mode, the amount of brake control
provided by active trace control is reduced.

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.

WARNING
●Never rely solely on the hill start assist sys-
tem to prevent the vehicle from moving back-
ward on a hill. Always drive carefully and
attentively. Depress the brake pedal when
the vehicle is stopped on a steep hill. Be
especially careful when stopped on a hill on
frozen or muddy roads. Failure to prevent the
vehicle from rolling backwards may result in
a loss of control of the vehicle and possible
serious injury or death.
● The hill start assist system is not designed
to hold the vehicle at a standstill on a hill.
Depress the brake pedal when the vehicle is
stopped on a steep hill. Failure to do so may
cause the vehicle to roll backwards and may
result in a collision or serious personal
injury.
● The hill start assist system may not prevent
the vehicle from rolling backwards on a hill
under all load or road conditions. Always be
prepared to depress the brake pedal to pre-
vent the vehicle from rolling backwards. Fail-
ure to do so may result in a collision or seri-
ous personal injury.
The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a
hill.
The hill start assist system will operate auto-
matically under the following conditions:
●
The transmission is shifted to a forward or
reverse gear.
● The vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds. After 2
seconds the vehicle will begin to roll back and
the hill start assist system will stop operating
completely.
The hill start assist system will not operate
when the transmission is shifted to the N
(Neutral) or P (Park) position or on a flat and
level road. The 4 Wheel Active Steer (4WAS) system is an
electronically controlled four-wheel steering
system.
Depending on the vehicle speed and steering
angle, the angles of the front and rear wheels
are adjusted by the 4WAS system to help
improve driving performance.
If a malfunction occurs in the system, the 4WAS
function will stop but the ordinary two-wheel
steering system will operate normally. The
“4WAS” warning light will illuminate. If the light
illuminates while you are driving, contact an
INFINITI retailer for repair.
The steering wheel may be slightly turned even
when driving on a straight road due to a
protection mechanism for the 4WAS system.
This is not a malfunction. The steering wheel
will return to the normal position after the
protection mechanism deactivates.
The protection mechanism activates under the
following conditions:
●
The steering wheel is operated forcibly when
it is hard to operate or the tires are blocked
by obstacles.
● The steering wheel is continuously operated
when the vehicle is parked or being driven at
extremely low speed.

●The steering wheel is forcibly turned beyond
its operation limits.
● The battery voltage is reduced.
Repeated steering maneuvers that may activate
the protection mechanism will damage the
4WAS system.
WARNING
The 4WAS system, although a sophisticated
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 4WAS system be fully
appreciated and safety optimized.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F (0°C),
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” section.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “BATTERY” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or
icy roads, INFINITI recommends the use of MUD
& SNOW or ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire type,
size, speed rating and availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires.
Skid and traction capabilities of studded snow
tires, on wet or dry surfaces, may be poorer than
that of non-studded snow tires.
Tire chains may be used. For details, see “TIRE
CHAINS” in the “8. Maintenance and do-it-
yourself” section of this manual.
For all-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.

Jacking up the vehicle and removing
the damaged tire
WARNING
●Never get under the vehicle while it is sup-
ported only by the jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Use only the jack provided with your vehicle
to lift the vehicle. Do not use the jack pro-
vided with your vehicle on other vehicles.
The jack is designed for lifting only your ve-
hicle during a tire change.
● Use the correct jack-up points. Never use any
other part of the vehicle for jack support.
● Never jack up the vehicle more than
necessary.
● Never use blocks on or under the jack.
● Do not start or run the engine while vehicle is
on the jack, as it may cause the vehicle to
move. This is especially true for vehicles
with limited slip differentials.
● Do not allow passengers to stay in the ve-
hicle while it is on the jack. Carefully read the caution label attached to the
jack body and the following instructions.
1. Place the jack directly under the jack-up
point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
Align the jack head between the two
notches in the front or the rear as shown.
Also fit the groove of the jack head be-
tween the notches as shown.
The jack should be used on level firm ground.
