ECU NISSAN PATHFINDER 2023 Repair Manual

WARNING
Apply the electronic parking brake if
the shif t lever is in any position while
the engine is not running. Failure to do
so could cause the vehicle to move un-
expectedly or roll away and result in
serious personal injury or property
damage.
CAUTION
• Use the P (Park), R (Reverse) or D
(Drive) position only when the vehicle
is completely stopped.
• When switching to the desired shif t
position by operating the shif t lever,
check that the shif t lever returns to
the home position by releasing your
hand from the lever. Holding the shif t
lever in a mid-way position may also
damage the shif t control system.
• Do not operate the shif t lever while
the accelerator pedal is depressed.
This may cause a sudden start which
could result in an accident. •
The following operations are not al-
lowed because excessive force
would be applied to the transmission
and this may result in damage to the
vehicle:
– Moving the shif t lever to the R (Re-
verse) position when driving
forward
– Moving the shif t lever to the D
(Drive) position when reversing
If these operations are attempted, a
chime sounds and the vehicle shif ts to
the N (Neutral) position.
If the vehicle is moving over 5 mph (8
km/h) when shif ting to D (Drive) from R
(Reverse), the N (Neutral) position will
automatically be selected. A buzzer will
sound, noting that D (Drive) was not se-
lected. When selecting D (Drive) while
reversing below 5 mph (8 km/h) the
range will change normally.
P (Park)
CAUTION
• To prevent transmission damage,
use the P (Park) position only when
the vehicle is completely stopped.
• Do not slide the shif t lever while
pressing the park button. This may
damage the shif t control system.
Use the P (Park) position when the vehicle is
parked or when starting the engine. Make
sure the vehicle is completely stopped be-
fore pressing the park button to engage
the P (Park) position. For maximum safety,
the brake pedal must be depressed before
engaging the P (Park) position. Use this po-
sition together with the electronic parking
brake. When parking on a hill, first depress
the brake pedal, apply the electronic park-
ing brake and then engage the P (Park)
position. The parking lock should not be
used as a brake when parking. In order to
secure the vehicle, always apply the elec-
tronic parking brake in addition to the park-
ing lock.

•Properly position the mats in the
floorwell using the floor mat posi-
tioning hook. For additional informa-
tion, see “Floor mat installation”
(P. 7-6 ).
• Make sure the floor mat does not in-
terfere with pedal operation.
• Periodically check the floor mats to
make sure they are properly
installed.
• Af ter cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle. When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the
shif t position in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t po-
sition in the P (Park) position and with
the parking brake applied, fully apply and
release all pedals. The floor mat must
not interfere with pedal operation or
prevent the pedal from returning to its
normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
floor mat positioning hooks.
