instrument panel INFINITI M 2011 Service 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.
