traction control NISSAN FRONTIER 2000 D22 / 1.G Owners Manual

CAUTION
Do not drive on dry hard surface roads
in four-wheel drive. Driving on dry hard
surfaces in 4H or 4L may cause unnec-
essary noise, tire wear, and increased
fuel consumption. NISSAN recom-
mends driving in the 2H position under
these conditions.
WARNING
IWhen parking the vehicle, apply the
parking brake and always make sure
to shift the transfer control lever into
the 2H, 4H or 4L position.
IDo not leave the transfer control le-
ver in the N (Neutral) position. Oth-
erwise, the vehicle could roll unex-
pectedly even if the manual
transmission is in gear or the auto-
matic transmission is in the P (Park)
position.
IFailure to engage the transfer con-
trol lever in 2H, 4H, or 4L could result
in the vehicle moving unexpectedly,
resulting in serious personal injury
or property damage.2HÐ (2WD, high range) Only the rear
wheels are driven. Use for driving under the
same conditions as standard 2WD vehicles
or state dynamometer I/M testing.
4HÐ (4WD, high range) Four wheels are
driven. Use when driving on roads where it
is difficult to drive in the 2H position (i.e.,
driving at normal speeds on snow covered,
icy, wet, muddy or sandy roads).
4LÐ (4WD, low range) Four wheels are
driven. Use when climbing or descending
steep hills, or during hard driving in sand,
mud or deep snow. The 4L position provides
maximum power and traction. Avoid raising
vehicle speed excessively, as the maximum
speed is approximately 30 MPH (48 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N (Neutral) position.
Shift the lever quickly and smoothly when
moving across the N (Neutral) position with
the vehicle stopped.
Your NISSAN is equipped with one of two
4WD systems, auto-lock free-running hubs
or manual-lock free-running hubs.

trailer must also pass the other vehicle
before you can safely change lanes.
ITo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
IAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change oil in the
transmission more frequently. For addi-
tional information see the ``Maintenance''
section earlier in this manual.DOT (Department of Transportation) Quality
Grades: All passenger car tires must con-
form to Federal Safety Requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However, rela-
tive tire performance depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades from highest to lowest
are AA, A, B, and C. Those grades repre-sent the tire's ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
