5-54Starting and driving
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test featureGUID-4FC5730B-9006-485D-8F47-48423827A0FDThe ABS includes electronic sensors, elec-
tric 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 pulsa-
tion 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 operates 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 operationGUID-4A24737D-9B87-4CFC-A807-4E8F57A64E71The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
GUID-9B2B3B86-188B-477E-85AC-1E8002A9BE3EThe Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, 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 func-
tion).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
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
warning light
in the instrument panel
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

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) warn-
ing light” (P.2-14).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically 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,
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) warn-
ing light” (P.2-14) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-16).
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 malfunction.
WARNING
. The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steering
operation at high speeds or by careless
or dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving 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 deteriorated, 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
recommended or are extremely deterio-
rated, 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
deteriorated, the VDC warning light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked corners,
the VDC system may not operate prop-
erly 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
recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

FREEING A FROZEN DOOR LOCKGUID-2C882469-11A3-4715-8BCB-FA19FFE0887FTo 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.
ANTIFREEZEGUID-C3261124-A271-4B19-A25E-63CCB5008F6AIn the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-8).
BATTERYGUID-F9CBEBD7-C133-422D-A36C-05EFDC8A701EIf the battery is not fully charged during
extremely 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”
(P.8-15).
DRAINING OF COOLANT WATERGUID-52E88C59-7722-46BD-A12A-8762FEB37D9CIf the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-8).
TIRE EQUIPMENTGUID-A19A4B63-2858-43F2-970D-016811637FE9SUMMER 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
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 prohi-
bit 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”(P.8-35) of this manual.
COLD WEATHER DRIVING

SPECIAL WINTER EQUIPMENTGUID-9E63915B-AEEB-4DF7-AE59-93BA4A80CE83It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades.
. 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 window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICEGUID-B958E8BB-93DC-4740-87FE-FFE84942F1FF
WARNING
. Wet ice (328F, 08C 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 cau-
tion. Accelerate and slow down with
care. If accelerating 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
slippery 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 the cruise control on slippery
roads.
. Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
GUID-225659C5-E0EC-4FA3-AF40-10B3DE04F272Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 208F
(−78C) or lower.
To use the engine block heaterGUID-403EC22E-E30C-4DE3-AC84-7E1C9EDC9E2B1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be
plugged in for at least 2 - 4 hours,
depending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.

the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure 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.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 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.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors (for models not equipped with the emergency tire puncture repair kit).
. If you used the Emergency Tire Sealant
to repair a minor tire puncture, your
INFINITI retailer will also need to replace
the TPMS sensor in addition to repairing
or replacing the tire (for models
equipped with the emergency tire punc-
ture repair kit).
. INFINITI recommends using only NISSAN
Genuine Emergency Tire Sealant pro-
vided with your vehicle. Other tire
sealants may damage the valve stem
seal which can cause the tire to lose air
pressure (for models equipped with the
emergency tire puncture repair kit).
CHANGING FLAT TIRE (for models
with spare tire)

Installing the spare tireGUID-003A0190-9B2C-45A9-A542-11B8BA923B48The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading“Wheels and tires” (P.8-
29).)
1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Check that all the wheel nuts contact
the wheel surface horizontally.
When replacing a front tire, make sure
that the hole in the spare tire wheel is
aligned with the pin on the brake rotor. 3. With the wheel nut wrench, tighten
wheel nuts alternately and evenly in the
sequence as illustrated (
*1,*2,*3,
*4,*5) until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
. Incorrect wheel nuts or improperly tigh-
tened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench. Wheel nut tightening torque:
80 ft-lb (108 N·m)
The wheel nuts must be kept tightened
to specifications at all times. It is
recommended that the wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for 3
hours or more or driven less than 1
mile (1.6 km).
COLD tire pressures are shown on the
Tire and Loading Information label
affixed to the driver side center pillar.
5. Securely store the flat tire and jacking equipment in the vehicle.
