CAUTION
To avoid possible damage to your ve-
hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this pur-
pose.
1. Af ter starting the engine, fully depress the foot brake pedal before moving the
shif t lever out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shif t lever into a driving
gear.
3. Release the foot brake, then gradually start the vehicle in motion.
4. Stop the vehicle completely before mov- ing the shif t lever into the P (Park)
position.
The Continuously Variable Transmission
is designed so the foot brake pedal MUST
be depressed before shif ting from P
(Park) to any drive position while the ig-
nition switch is in the ON position.
The shif t lever cannot be moved out of P
(Park) and into any of the other gear po-
sitions if the ignition switch is placed in
the LOCK, OFF or ACC position. To move the shif t lever:

P (Park)
CAUTION
To prevent transmission damage, use
the P (Park) position only when the ve-
hicle is completely stopped.
Use the P (Park) shif t lever position when
the vehicle is parked or when starting the
engine. Make sure the vehicle is completely
stopped. The brake pedal must be de-
pressed and the shif t lever button
pressed in to move the shif t 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 shif t lever into the P (Park) position.
R (Reverse)
CAUTION
To prevent transmission damage, use
the 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 the R (Reverse)
position. The brake pedal must be de-
pressed and the shif t lever button pressed in to move the shif t lever from P
(Park), N (Neutral) or any drive position to
R (Reverse).
N (Neutral)
Neither forward nor reverse gear is en-
gaged. The engine can be started in this
position. You may shif t 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) (if so equipped)
Use this position for maximum engine
braking on steep downhill gradients/
climbing steep slopes and whenever ap-
proaching sharp bends. Do not use the L
(Low) position in any other circumstances.
Manual shif t mode (if so
equipped)
When the shif t lever is in the manual shif t
gate, the transmission is ready for the
manual shif t mode. Shif t ranges can be
selected manually by moving the shif t le-
ver up or down. To cancel manual shif t
mode, return the shif t lever to the D (Drive)position. The transmission returns to auto-
matic driving mode.
When the shif t lever is shif ted from D (Drive)
to the manual shif t gate with the vehicle
stopped or while driving, the transmission
enters the manual shif t mode. Shif t ranges
can be selected manually. In the manual
shif t mode, the shif t range is displayed on
the position indicator in the meter. When
moving the shif t lever to the manual shif t
gate, the position indicator displays 1 (1st)
up to 7 (7th) depending on vehicle speed.
Shif t ranges up or down one by one as
follows:
1⇔
2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7
M7 (7th)
Use this position for all normal forward
driving at highway speeds.
M6 (6th) and M5 (5th)
Use this position when driving up long
slopes or for engine braking when driving
down long slopes.
M4 (4th), M3 (3rd) and M2 (2nd)
Use for hill climbing or engine braking on
downhill grades.
5-18Starting and driving

M1 (1st)
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
sand or mud, or for maximum engine brak-
ing on steep downhill grades.
• Remember not to drive at high speeds forextended periods of time in lower than
the 6th range. This reduces fuel economy.
When shif ting up
Move the shif t lever to the + (up) side. (Shif ts
to higher range.)
When shif ting down
Move the shif t lever to the − (down) side.
(Shif ts to lower range.)
• Moving the shif t lever rapidly to the same side twice will shif t the ranges in succes-
sion.
• The transmission will automatically downshif t the gears. (For example, if you
select the 3rd range, the transmission will
shif t down between the 3rd and 1st
gears.)
When canceling the manual shif t mode
Return the shif t lever to the D (Drive) posi-
tion to return the transmission to the nor-
mal driving mode. •
In the manual shif t mode, the trans-
mission may not shif t to the selected
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
• When this situation occurs, the Con-
tinuously Variable Transmission (CVT)
position indicator light will blink and
the chime will sound.
• In the manual shif t mode, the trans-
mission may shif t up automatically to a
higher range than selected if the en-
gine speed is too high. When the ve-
hicle speed decreases, the transmis-
sion automatically shif ts down and
shif ts to 1st gear before the vehicle
comes to a stop.
• CVT operation is limited to automatic drive mode when CVT fluid temperature
is extremely low even if manual shif t
mode is selected. This is not a malfunc-
tion. When CVT fluid warms up, manual
mode can be selected.
• When the CVT fluid temperature is high, the shif t range may upshif t in lower rpm
than usual. This is not a malfunction.
Shif t lock release
If the battery charge is low or discharged,
the shif t lever may not be moved from the
P (Park) position even with the brake pedal
depressed and the shif t lever button
pressed.
It will be necessary to jump start or have
your battery charged. For additional infor-
mation, refer to “Jump starting” in the “In
case of emergency” section of this manual.
It is recommended that you contact a
NISSAN dealer or a professional towing ser-
vice.
LSD3739

OFF position:
For normal driving and fuel economy, use
the OFF position.
ON position:
For driving up or down long slopes where
engine braking is necessary, or for powerful
acceleration, use the ON position. The
transmission will automatically select a dif-
ferent gear ratio, allowing the engine to
provide high output.
Remember not to drive at high speeds for
extended periods of time with the drive
sport mode in the ON position. This re-
duces fuel economy.
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
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, refer to “Malfunction Indicator
Light (MIL)” in the “Instruments and con-
trols” section of this manual. This will oc-
cur even if all electrical circuits are func-
tioning properly. In this case, place the
ignition switch in the OFF position and
wait for 10 seconds. Then push the
switch back to the ON position. The ve-
hicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have the
transmission checked and repaired, if
necessary. It is recommended that you
visit a NISSAN dealer for this service.
WARNING
When the high fluid temperature pro-
tection mode or fail-safe operation oc-
curs, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could in-
crease the chance of a collision. Be es-
pecially careful when driving. If neces-
sary, pull to the side of the road at a safe
place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
MANUAL TRANSMISSION (if so
equipped)
CAUTION
• Do not rest your foot on the clutch
pedal while driving. This may cause
clutch damage.
• Fully depress the clutch pedal before
shif ting to help prevent transmission
damage.
• Stop your vehicle completely before
shif ting into R (Reverse).
Starting and driving5-21

•When the vehicle is stopped with the
engine running (for example, at a
stop light), shif t to N (Neutral) and re-
lease the clutch pedal with the foot
brake applied.
• Do not shif t to the N (Neutral) posi-
tion while driving. Doing so may re-
sult in an accident due to loss of en-
gine braking.
Shif ting
To change gears or when upshif ting or
downshif ting, depress the clutch pedal
fully, shif t into the appropriate gear, then
release the clutch slowly and smoothly.
To ensure smooth gear changes, fully de-
press the clutch pedal before operating the
shif t lever. If the clutch pedal is not fully
depressed before the transmission is
shif ted, a gear noise may be heard. Trans-
mission damage may occur.
Start the vehicle in 1st gear and shif t to 2nd,
3rd, 4th and 5th up to 6th gear in sequence
according to vehicle speed. To back up, lif t up on the shif t lever ring
O1
and then move it to the R (Reverse) position
af ter stopping the vehicle completely.
The shif t lever ring
O1returns to its original
position when the shif t lever is moved to
the N (Neutral) position.
If it is difficult to move the shif t lever into R
(Reverse) or 1 (1st), shif t into N (Neutral), then
release the clutch pedal. Depress the
clutch pedal again and shif t into R (Re-
verse) or 1 (1st).
Suggested up-shif t speeds
The following are suggested vehicle
speeds for shif ting into a higher gear.
These suggestions relate to fuel economy
and vehicle performance. Actual upshif t

The TSR system provides the driver with
information about the most recently de-
tected speed limit. The system captures
the road sign information with the multi-
sensing front camera unit
O1located on
the windshield in front of the inside rear-
view mirror and displays the detected
signs in the vehicle information display. For
vehicles equipped with a navigation sys-
tem, the speed limit displayed is based on a
combination of navigation system data
and live camera recognition. TSR informa-
tion is always displayed at the top of the vehicle information display, and optionally
in the main central area of the display
screen.

Action to take:
When the interior temperature is reduced,
the TSR system will resume operating au-
tomatically.
SYSTEM MALFUNCTION
If the TSR system malfunctions, it will be
turned off automatically and the system
“Malfunction” warning message will appear
in the vehicle information display.
Action to take:
If the TSR “Malfunction” message appears,
pull of the road at a safe location and stop
the vehicle. Turn the engine off and restart
the engine. If the TSR “Malfunction” mes-
sage continues to appear, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, refer to ”Sys-
tem maintenance” in the “Lane Departure
Warning (LDW)” section.

•The system may not function prop-
erly under the following conditions:
– On roads where there are multiple
parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers;
or lane markers covered with wa-
ter, dirt, snow, etc.
– On roads where the discontinued
lane markers are still detectable.
– On roads where there are sharp
curves.
– On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The LDW system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range. –
When rain, snow, dirt or an object
adheres to the windshield in front
of the lane camera unit.
– When the headlights are not
bright due to dirt on the lens or if
the aiming is not adjusted
properly.
– When strong light enters the lane
camera unit. (For example, the
light directly shines on the front of
the vehicle at sunrise or sunset.)
– When a sudden change in bright-
ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
SYSTEM TEMPORARILY
UNAVAILABLE
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the LDW system may be deacti-
vated automatically and the following
message will appear in the vehicle infor-
mation display: “Unavailable: High Cabin
Temperature.”
When the interior temperature is reduced,
the LDW system will resume operating au-
tomatically. The LDW system is not designed to warn
under the following conditions:
• When you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDW system will
become operable again approximately 2
seconds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the LDW functions will resume.
SYSTEM MALFUNCTION
