Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.

1-60Safety—Seats, seat belts and supplemental restraint system

When the VDC OFF 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
indicator flashes if this oc-
curs. All other VDC functions are off and
the
indicator 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.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward 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 indica-
tion 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 al-
ways drive carefully. ∙ Do not modif y the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the
indicator may flash or
the
indicator light may
illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and both
the
andindicator lights
may illuminate.
∙ If engine control related parts are not NISSAN recommended or are ex-
tremely deteriorated, both the
and theindicator lights may
illuminate. ∙ When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator may
flash or the
indicator 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
indicator may flash or
the
indicator light may illumi-
nate. This is not a malfunction. Re-
start the engine af ter driving onto a
stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator may
flash or the
indicator light may
illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
5-84Starting and driving

BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the front and rear wheels
depending on the radius of the turn.
WARNING
∙ The VDC system is designed to helpthe 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 al-
ways drive carefully.
∙ Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the
indicator may flash or
the
indicator light may
illuminate. ∙ If brake related parts such as brake
pads, rotors and calipers are not

Starting and driving5-85

NOTE:
Tire chains are not permitted for use
with 18 in wheels.
Wheel sizeMinimum space re-
quired
16 in .7 in (17 mm)
17 in .2 in (4 mm)
A tire chain that provides the specified
amount of space will provide the neces-
sary clearance between the tire and the
closest vehicle suspension or body com-
ponent. The minimum clearances are de-
termined using the factory-equipped tires.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain
must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when using
tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels. Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can
cause damage to the various mechanisms
of the vehicle due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 5,000 miles (8,000 km).
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
of this manual.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
