fuel consumption NISSAN PATHFINDER 2002 R50 / 2.G Owners Manual

2HÐ (2WD, high range) Only the rear wheels
are driven. Use for driving under the same
conditions as standard 2WD vehicle, 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).
The 4H position provides maximum power
and traction. Avoid excessive speed, as it
will cause loss of traction. Speed over 50
MPH (80 km/h) in 4H is not recommend.
4LÐ (4WD, low range) Four wheels aredriven. Use when climbing or descending
steep hills, or during hard driving in sand, mud
or deep snow. The 4L position provides maxi-
mum power and traction. Avoid raising vehicle
speed excessively, as the maximum speed is
approximately 30 MPH (50 km/h).
NÐ No wheels are driven. Always keep the
transfer lever out of the N position. Shift the
lever quickly and smoothly when moving
across the N position with the vehicle stopped.
CAUTION
Do not drive the vehicle in 4H or 4L on
dry hard surface roads. Driving on dry,
hard surfaces in 4H or 4L may cause
unnecessary noise, tire wear and in-
creased fuel consumption.
WARNING
IWhen parking the vehicle, apply the
parking brake and shift the transfer
control lever in the 2H, 4H or 4L
position.IDo not leave the transfer control lever
in the N position. Otherwise, the ve-
hicle could roll unexpectedly even if
the manual transmission is in any
gear or the automatic transmission in
the P position. If the ATP light is on,
this indicates that the automatic
transmission P position will not func-
tion and the transfer lever is in neu-
tral.
IFailure to engage the transfer control
lever in 2H, 4H or 4L could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage.

fuel additives (i.e.: fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvents or similar
ingredients that can be harmful to the fuel
system and engine.Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number
(VQ35DE engine) or 87 AKI (Anti-knock Index)
number (VG33E engine). However, you may
use unleaded gasoline with an octane rating
as low as 85 AKI (Anti-Knock Index) number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knockwhile holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time.
