5. To stop the engine, move the shif t leverto the P (Park) position and push the
ignition switch to the OFF position.
In preparation for the next engine start, the
engine may have a slightly delayed shutoff
af ter placing the ignition switch in the OFF
position, depending on the driving condi-
tions.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly
and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.

To push the shif t lock release, complete the
following procedure:1. Place the ignition switch in the LOCK position.
2. Apply the parking brake.
3. Remove the shif t lock release cover. If a screwdriver is used to remove the
cover, it should be wrapped in a protec-
tive cloth to prevent damage to the
cover and surrounding plastic.
4. Insert a small object or finger in the shif t lock release slot and push.
5. Move the shif t lever to the N (Neutral) position while holding the shif t lock re-
lease.
6. Now the vehicle may be moved to the desired location.
If the shif t lever cannot be moved out of P
(Park), have the automatic transmission
system checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.WARNING
If the shif t lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and
others.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, please
note that the transmission will be locked in
any of the forward gears according to the
condition. If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
This will occur even if all electrical cir-
cuits are functioning properly. In this
case, place the ignition switch in the OFF
position and wait for 3 seconds. Then
place the ignition switch back in the ON
position. The vehicle should return to its
normal operating condition. If it does not
return to its normal operating condition,
have the transmission checked and re-
paired, if necessary. It is recommended
that you visit a NISSAN dealer for this
service.
5-22Starting and driving

*1: Before moving the shif t lever from N (Neutral), wait until the 4LO indicator stays on steady. This indicates that the 4WD shif t procedureis completed and the transfer gear is correctly set in the 4LO position. If the vehicle is shif ted into gear before the indicator is on steady,
the transfer gear may grind, not engage correctly or stay in the N (Neutral) position.
- If the 4WD vehicle information display warning message illuminates, perform the following procedure to return the transfer case to
the correct operating condition.
1. Turn off the engine by placing the ignition switch in the OFF position.
2. Start the engine.
- Check that the 4WD vehicle information display warning message turns of f. If the warning message in the vehicle information display
stays on, have the system checked. It is recommended that you visit a NISSAN dealer for this service.
3. Apply the parking brake, depress the brake pedal and move the shif t lever to the N (Neutral) position.
4. With the brake pedal depressed, move the 4WD shif t switch to the desired mode.
- Be sure to wait until the transfer gear change completes before shif ting the shif t lever from the N (Neutral) position.
*2: While changing in and out of 4LO, the ignition switch must be in the ON position and the vehicle’s engine must be running for a shif t to take place and for the 4WD shif t and 4LO position indicators to be operable. Otherwise, the shif t will not take place and no indicators
will be on or flashing.
*3: Make sure the transfer 4LO position indicator turns on when you shif t the 4WD shif t switch to 4LO. The
indicator light will also turn
on when 4LO is selected. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.

– In the 4H position, shif t the 4WDshif t switch to 2WD.
– In the 4LO position, stop the ve- hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
∙ If the warning message is still on af ter the above operation, have your ve-
hicle checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
∙ The transfer case may be damaged if you continue driving with the warning
message on. The E-Lock system can provide additional
traction and should only be used when a
vehicle has become or is becoming stuck.
This system operates by electronically
“locking” the two rear drive wheels to-
gether, allowing them to turn at the same
speed. The system is used when it is not
possible to free a stuck vehicle even when
using the 4LO position (4-Wheel Drive ve-
hicles).
When added traction is required, activate
the E-Lock system by pushing the switch
on. For additional information, refer to
“Electronic locking rear differential (E-Lock)
system switch” in the “Instruments and
controls” section of this manual. Once the
system fully engages, the indicator light in
the instrument panel will remain on. When
the system is activated, both rear wheels
will engage, providing added traction.
The rear wheels may momentarily slip or
move to engage the system, and the sys-
tem will only engage up to approximately
4 mph (7 km/h). Once the vehicle is free, the
system should be turned off and driving
resumed.
The Anti-lock Braking System (ABS) is dis-
abled and the ABS warning light illumi-
nates when the E-Lock system is on.WARNING
∙ Never leave the E-Lock system on
when driving on paved or hard-
surfaced roads. Turning the vehicle
may result in the rear wheels slipping
and result in an accident and personal
injury. Af ter using the E-Lock system
to free the vehicle, turn the system off.
∙ Use the E-Lock system only in an emergency when it is not possible to
free a stuck vehicle even when using
4LO. Never use the E-Lock system on a
slippery road surface such as snow or
ice surface. Using the E-Lock system
when driving in these road conditions
may cause unexpected movement of
the vehicle during engine braking, ac-
celerating or turning, which may re-
sult in an accident and serious per-
sonal injury.
∙ Observe the above warnings. Other- wise, loss of normal steering control
may result. This may result in an acci-
dent and serious personal injury.

DIFFERENTIAL (E-Lock) SYSTEM (if
so equipped)
5-52Starting and driving

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric 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 pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds above3-6mph(5-
10 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
