– For detailed information, see Wheels and
tires in the 8. Do-it-yourself section.
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 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 “clunk” 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. It is recommended you visit an
INFINITI retailer for this service.
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.

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 maintain
control of the vehicle in the following condi-
tions:– understeer (vehicle tends to not follow the steered path despite increased steering
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 sec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
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 driv- ing and cornering on slippery surfaces and
always drive carefully.
•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
properly. This could adversely affect vehicle
handling 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 sur-
faces such as higher banked corners, the
VDC system 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
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-90Starting and driving

VDC warning lightmay illuminate. This
is not a malfunction. Restart the engine af-
ter driving onto a stable surface.
•If wheels or tires other than the INFINITI
recommended ones are used, the VDC sys-
tem may not operate properly and the VDC
warning light
may illuminate.
•The VDC system is not a substitute for win-
ter tires or tire chains on a snow covered
road.
•If VDC is malfunctioning, VDC is unable to
stabilize the vehicle. In addition, other driv-
ing safety systems are switched off. This
increases the risk of skidding and an acci-
dent. Drive on carefully. Have VDC checked.
It is recommended you visit an INFINITI re-
tailer for this service.
CAUTION
•When VDC is deactivated, theVDC
OFF warning light lights up continuously.
•If both thewarning light andwarning light are lit continuously, VDC is
not available due to a malfunction.
TRACTION CONTROL SYSTEM (TCS)
The Traction Control System (TCS) is part of
VDC..
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deactivate
VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.
If VDC intervenes, the
VDC warning lamp
flashes in the combination meter.
If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the accel-
erator pedal as far as is necessary.
•Adapt your driving style to suit the prevailing
road and weather conditions.
Deactivating/activating VDC
WARNING
If you deactivate VDC, VDC no longer stabilizes
the vehicle. There is an increased risk of skid-
ding and an accident.
Only deactivate VDC in the situations de-
scribed in the following section.
You can select between the following statuses
of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the follow-
ing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel.
NOTE
Activate VDC as soon as the situations described
above no longer apply. VDC will otherwise not be
Starting and driving5-91

able to stabilize the vehicle if the vehicle starts
to skid or a wheel starts to spin.
You can activate/deactivate VDC using the ve-
hicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press the button on the steering wheel.
The current selection is displayed.
5. To activate/deactivate: press the but-
ton again.
VDC is deactivated if the
warning light
in the combination meter lights up continu-
ously when the engine is running.
Characteristics when VDC is deactivated
:
If VDC is deactivated and one or more wheels
start to spin, theVDC warning lamp
flashes in the combination meter. In such situ-
ations, VDC will not stabilize the vehicle. If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE FORCE
DISTRIBUTION)
EBD monitors and controls the brake pressure
on the rear wheels to help improve handling
during braking.
WARNING
If EBD is malfunctioning, the EBD [Inoperative
See Operator’s Manual] warning is displayed
in the vehicle information display. The
VDC warning lamp may also light up.
If EBD is malfunctioning as a result of a VDC
malfunction, the rear wheels can lock, e.g. un-
der full braking. This increases the risk of skid-
ding and an accident.You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked. It is recommended
you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisa-
tion.
This steering support is provided in particular if:
•Both right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from STEER
CONTROL, if:
•VDC is malfunctioning.
•The steering is faulty.
Power steering will, however, continue to
function.

TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, INFINITI recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. It is rec-
ommended that you visit an INFINITI retailer
for the tire type, size, speed rating and
availability information.
2. 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.
3. Tire chains may be used if desired. Make sure they are the proper size for the tires on
your vehicle and are installed according to
the chain manufacturer’s instructions. Use
chain tensioners when recommended by the
tire chain manufacturer to ensure a tight fit. Loose end links of the tire chains must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. In addition, drive at a reduced
speed, otherwise, your vehicle may be dam-
aged and/or vehicle handling and perfor-
mance may be adversely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to remove
ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snowdrifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
•Wet ice (32°F, 0°C and freezing rain), very
cold snow or ice can be slick and very hard
to drive on. The vehicle will have much less
traction or “grip” under these conditions.
Try to avoid driving on wet ice until the road
is salted or sanded.
•Whatever the condition, drive with caution.
Accelerate and slow down with care. If ac-
celerating or downshifting too fast, the
drive wheels will lose even more traction.
•Allow more stopping distance under these
conditions. Braking should be started
sooner than on dry pavement.
•Allow greater following distances on slip-
pery roads.
•Watch for slippery spots (glare ice). These
may appear on an otherwise clear road in
shaded areas. If a patch of ice is seen ahead,
brake before reaching it. Try not to brake
while on the ice, and avoid any sudden
steering maneuvers.
•Do not use cruise control on slippery roads.
•Snow can trap dangerous exhaust gas un-
der your vehicle. Keep snow clear of the
exhaust pipe and from around your vehicle.

The hazard warning flasher switch1operates
regardless of the ignition switch position except
when the battery is discharged.
The hazard warning flasher is used to warn
other drivers when you have to stop or park
under emergency conditions.
When the hazard warning flasher switch is
pushed, all turn signal lights will flash. To turn
off the hazard warning flasher, push the hazard
warning switch again.
WARNING
•If stopping for an emergency, be sure to
move the vehicle well off the road.
•Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive so
slowly that your vehicle might become a
hazard to other traffic.
•Turn signals do not work when the hazard
warning flasher lights are on.
Some jurisdictions may prohibit the use of the
hazard warning flasher switch while driving. If you have a flat tire, follow the instructions in
this section.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
WARNING
•If the low tire pressure warning light illumi-
nates or a tire pressure-related warning is
displayed by the vehicle information dis-
play while driving, avoid sudden steering
maneuvers or abrupt braking, reduce ve-
hicle speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as pos-
sible. Driving with under-inflated tires may
permanently damage the tires and increase
the likelihood of tire failure. Serious vehicle
damage could occur and may lead to an ac-
cident and could result in serious personal
injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the recom-
mended COLD tire pressure shown on the
tire and loading information label to turn
the low tire pressure warning light OFF. If
you have a flat tire, replace it with a replace-
ment tire as soon as possible.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light

HAZARD WARNING FLASHER SWITCH
FLAT TIRE
6-2In case of emergency

In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions/
maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the vehicle information dis-
play.
You must not exceed a maximum speed of 50
MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle’s tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be used
as a temporary measure. Make sure that you
use the proper size and type (summer or winter
tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneuvers,
and driving over obstacles (curbs, pot holes,
off road). This applies in particular to a laden
vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the tire.
After driving in emergency mode, have the
wheel rims checked with regard to their further
use. It is recommended you visit an INFINITI
retailer for this service. The faulty tire must be
replaced.
REMOVING AND FITTING WHEELS
NOTE
A spare wheel is not provided with your vehicle.
Blocking the wheels
WARNING
Make sure to block the appropriate wheel to
prevent the vehicle from moving, which may
cause personal injury.
Place suitable blocks
1in front of and behind
the wheel diagonally opposite the flat tire
Ato
prevent the vehicle from moving when it is on
the jack.
