pedal and move the shift lever from P (Park) to
any of the desired shift positions.
WARNING
● Apply the parking brake if the shift lever
is in any position while the engine is not
running. Failure to do so could cause
the vehicle to move unexpectedly or roll
away and result in serious personal in-
jury or property damage.
If the key is turned to the OFF or ACC position for
any reason while the vehicle is in N (Neutral) , or
any drive position, the key cannot be turned to the
LOCK position and be removed from the ignition
switch. If this occurs, perform the following steps: 1. Apply the parking brake when the vehicle is stopped.
2. Move the shift lever to P (Park) to park the vehicle and turn the ignition switch to the
LOCK position to remove the key.
P (Park):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the P (Park) shift lever position when the
vehicle is parked or when starting the engine. Make sure the vehicle is completely stopped.
The brake pedal must be depressed and
the shift lever button pushed in to move the
shift lever from N (Neutral) or any drive
position to P (Park) .
Apply the parking brake.
When parking on a hill, apply the parking brake
first, then place the shift lever into the P (Park)
position.
R (Reverse):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the R (Reverse) position to back up. Make
sure the vehicle is completely stopped before
selecting R (Reverse) position. The brake
pedal must be depressed and the shift lever
button pushed in to move the shift lever
from P (Park) , N (Neutral) or any drive po-
sition to R (Reverse) .
N (Neutral):
Neither forward nor reverse gear is engaged. The
engine can be started in this position. You may
shift to N (Neutral) and restart a stalled engine
while the vehicle is moving.

D (Drive):
Use this position for all normal forward driving.
L (Low):
Use this position for maximum engine braking on
steep downhill gradients/climbing steep slopes
and whenever approaching sharp bends. Do not
use the L (Low) position in any other circum-
stances.
Shift lock release
If the battery charge is low or discharged, the
shift lever may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift lever button pressed.
It will be necessary to jump start or have your
battery charged, see “Jump starting” in the “In
case of emergency” section. Contact your
NISSAN dealer or a professional towing service.
To move the shift lever, complete the following
procedure:1. Press the ignition switch to the LOCK posi- tion. 2. Apply the parking brake.
3. Using a protective cloth on the tip ofa3mm
screwdriver, remove the shift lock release
cover.
● If available, a plastic trim tool can also be
used.
4. Insert the small screwdriver in the shift lock release slot and push down.
5. Move the shift lever to the N (Neutral) posi- tion while holding down the shift lock re-
lease.
6. Push the ignition switch to the ON position to unlock the steering wheel. Now the ve-
hicle may be moved to the desired location.
If the shift lever cannot be moved out of P (Park) ,
have a NISSAN dealer check the transmission as
soon as possible.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.

Overdrive (O/D) OFF switch
When the O/D OFF switch is pushed with the
shift lever in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light (CVT models)” in the
“Instruments and controls” section of this manual.
Use the Overdrive off mode when you need im-
proved engine braking.
To turn off the Overdrive off mode, push the O/D
OFF switch again. The
indicator light will
turn off.
Each time the engine is started, or when the shift
lever is shifted to any position other than D (Drive) , the Overdrive off mode will be automati-
cally turned off.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, the CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction Indicator Light
(MIL)” in the “Instruments and controls”
section. This will occur even if all electrical
circuits are functioning properly. In this
case, place the ignition switch in the OFF
position and wait for 10 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 a NISSAN dealer check the transmis-
sion and repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially careful
when driving. If necessary, pull to the side
of the road at a safe place and allow the
transmission to return to normal opera-
tion, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
●
Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Do not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
● Do not shift to the N (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.

CAUTION
●Do not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
● Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
● Stop your vehicle completely before
shifting into R (Reverse) .
● When the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.
● Do not shift to the “N” (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.
Shifting
To change gears or when upshifting or down-
shifting, depress the clutch pedal fully, shift into
the appropriate gear, then release the clutch
slowly and smoothly.
To ensure smooth gear changes, fully depress
the clutch pedal before operating the shift lever. If
the clutch pedal is not fully depressed before the
transmission is shifted, a gear noise may be
heard. Transmission damage may occur.
Start the vehicle in 1st gear and shift to 2nd, 3rd,
4th and 5th up to 6th gear in sequence according
to vehicle speed. To back up, lift up on the shift lever ring
1and
then move it to the R (Reverse) position after
stopping the vehicle completely.
The shift lever ring
1returns to its original posi-
tion when the shift lever is moved to the N (Neu-
tral) position.
If it is difficult to move the shift lever into R
(Reverse) or 1 (1st) , shift into N (Neutral) , then
release the clutch pedal. Depress the clutch
pedal again and shift into R (Reverse) or 1 (1st) .

The cruise control is automatically canceled if:● you depress the brake or clutch pedal while
pushing the ACCEL/RES or SET/COAST
switch. The preset speed is deleted from
memory.
● the vehicle slows down more than 8 MPH
(13 km/h) below the set speed.
● you depress the clutch pedal (manual trans-
mission) , or move the shift lever to N (Neu-
tral) (CVT) .
To reset at a faster cruising speed, use one of
the following three methods.
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch.
When the vehicle attains the speed you de-
sire, release the switch.
● Push and release the ACCEL/RES switch.
Each time you do this, the set speed in-
creases by about 1 MPH (1.6 km/h). To reset at a slower cruising speed,
use one
of the following three methods.
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. Re-
lease the switch when the vehicle slows to
the desired speed.
● Push and release the COAST/SET switch.
Each time you do this, the set speed de-
creases by about 1 MPH (1.6 km/h).
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h).CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these rec-
ommendations may result in shortened
engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 RPM.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 mi
(800 km) . Your engine, axle or other parts
could be damaged.

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops
● Use smooth, gentle accelerator and
brake application whenever possible
● Maintain constant speed while commut-
ing and coast whenever possible
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops
● Maintaining a steady speed can minimize
red light stops and improve fuel efficiency
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load ●
Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes
● Select a gear range suitable to road con-
ditions
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains 6.
Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time
7. Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling
FUEL EFFICIENT DRIVING TIPS
5-26Starting and driving

10.Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system
11. ECO Mode
● The ECO mode helps to enhance the fuel
economy by controlling the engine and CVT
(if so equipped) operation automatically to
avoid rapid acceleration. ●
Keep your engine tuned up.
● Follow the recommended scheduled main-
tenance.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● Use the recommended viscosity engine oil.
See “Engine oil and oil filter recommenda-
tions” in “Technical and consumer informa-
tion” in this manual.
INCREASING FUEL ECONOMY

WARNING
●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire. ●
Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) for
CVT models or in an appropriate gear
for manual transmission models. Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as
it can go and cannot be moved without
depressing the foot brake pedal.
● Never leave the engine running while
the vehicle is unattended. ●
Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.
2. Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Continuously Variable Transmission
(CVT) models:
Move the shift lever into the P (Park) posi-
tion.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
● HEADED DOWNHILL WITH CURB:
1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
