cause a loss of control or engine
damage.
CAUTION
. Do not rest your foot on the
clutch pedal while driving. This
may damage the clutch.
. Fully depress the clutch pedal
before shifting to help prevent
transmission damage.
. Stop your vehicle completely be-
fore 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.

Shifting
To change gears, or when upshifting or
downshifting, fully depress the clutch
pedal, shift into an appropriate gear, and
then slowly and smoothly release the
clutch pedal.
This vehicle is equipped with a short
throw shifter manual transmission. To
ensure smooth gear changes, be sure to
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 could
occur.
Start the vehicle in 1st gear and upshift to2nd, 3rd, 4th, 5th and 6th gear in
sequence according to the vehicle speed.
To back up, depress the shift knob and
then move the shift lever to the R
(Reverse) position after stopping the ve-
hicle completely.
The shift knob returns to its original
position when the shift lever is moved to
the N (Neutral) position.
If it is difficult to move the shift lever into
R (Reverse) or 1st (Low gear), shift to N
(Neutral), then release the clutch pedal.
Fully depress the clutch pedal again and
shift into R or 1st.
SynchroRev Match mode (S-MODE)
(if so equipped for Manual Trans-
mission models)
The SynchroRev Match mode (S-MODE)
automatically adjusts the engine speed to
match the selecting gear ratio while
changing gears.
Precautions:
.
Shift lever and clutch pedal operations
are not different than a conventional
manual transmission.
. Fully depress the clutch pedal. Insuffi-
cient pedal depression may cause
slow response of this system. .
When the clutch pedal is depressed
with the gear still engaged, the engine
speed is kept at the proper level for
the engaged gear. Thus, the engine
speed may be kept high depending on
the gear position and vehicle speed.
. When the clutch pedal is depressed
with the transmission in neutral, the
system operates for approximately 2
seconds, and then the engine speed
will decrease to the idle speed.
. When the engine coolant temperature
is low right after starting the engine,
engine speed synchronization will be
delayed or may be insufficient.
. The system controls the engine speed
up to the rev limit. Note that S-MODE
is not a function that prevents over-
revving resulting from shifting mis-
takes.
. The system does not operate while
the vehicle is backing up.
. If the engine speed is limited lower
than usual when the engine oil tem-
perature is extremely high, the system
will control up to the limited engine
speed.
. If the malfunction indicator light illu-
minates, the system may not operate
and the S-MODE indicator turns off.

SynchroRev Match mode (S-MODE)
warning:
The SynchroRev Match mode (S-MODE)
warning will appear on the vehicle infor-
mation display and the S-MODE indicator
will turn off if a system malfunction
occurs.
If the warning appears, the S-MODE func-
tion will not operate, but manual trans-
mission will operate normally and driving
can be continued. Have the system
checked. It is recommended you visit a
NISSAN dealer for this service.
SSD0831
Activating the system:
To activate the S-MODE, push the S-
MODE switch
. The S-MODE indicatoron the tachometer will show “S”. To
deactivate, push and hold the S-MODE
switch for more than 1 second. The S-
MODE indicator will turn off.While the S-MODE is off, you can drive the
vehicle as a conventional manual trans-
mission model.
Note that the status of the S-MODE (on or
off) is memorized even after the ignition
switch is turned off; however, it will be
initialized (off) when the battery is dis-
connected.
The transmission position indicator
shows the selected gear: N (Neutral), 1, 2,
3, 4, 5, 6, R (Reverse).
SynchroRev Match mode (S-MODE) op-
eration:
The SynchroRev Match mode (S-MODE)
automatically adjusts the engine speed
by controlling the engine throttle. The
accelerator pedal does not have to be
depressed.
The system detects the clutch pedal and
shift lever operations, and then calculates
the target engine speed using the shifting
gear position and the vehicle speed
information.
The system provides accurate engine
speed control that helps achieve quick
gear shifting and reduces shift shock on
clutch engagement.
.
When downshifting:
The engine speed is automatically
increased to the target engine speed
Starting and driving5-19

5-20Starting and driving
before the clutch is engaged.
. When upshifting:
The engine speed is automatically
kept after the engine speed lowers to
the target engine speed.
Rapid clutch engagement before the
engine speed lowers to the target
engine speed may cause shift shock.
. When depressing the clutch pedal
with the gear engaged:
The engine speed is automatically
kept at the proper engine speed for
the engaged gear.
This function will not operate when
low (1st) gear is selected.
There is a delay between the clutch
pedal operation and the S-MODE op-
eration. Make sure the engine speed is
adjusted before engaging the clutch
again.
SSD0832
Upshift indicator
The up-shift indicator is located in the
tachometer and shows the driver the
timing to shift into a higher gear by
illuminating. The use of the up-shift
indicator will help you to upshift at a
constant engine speed from any gear.
The up-shift indicator will start flashing
when the engine speed reaches about
500 rpm before the set figure while
driving, and then illuminate after the
engine speed reaches the set figure.
The engine speed for upshifting can be
set on the vehicle information display. See
“Trip computer” (P.2-23). There may be a slight difference be-
tween the timing of the up-shift indica-
tor illumination and the tachometer
indication.
Suggested up-shift speeds
Shown below are suggested vehicle
speeds for shifting into a higher gear.
These suggestions relate to fuel economy
and vehicle performance. Actual up-shift
speeds will vary according to road condi-
tions, the weather and individual driving
habits.

released before driving. Failure to
do so can cause brake failure and
lead to an accident.
. Do not release the parking brake
from outside the vehicle.
. Do not use the shift lever in place
of the parking brake. When park-
ing, be sure the parking brake is
fully engaged.
. To help avoid risk of injury or
death through unintended opera-
tion of the vehicle and/or its
systems, do not leave children,
people who require the assis-
tance of others or pets unat-
tended in your vehicle.
Additionally, the temperature in-
side a closed vehicle on a warm
day can quickly become high
enough to cause a significant risk
of injury or death to people and
pets.

PRECAUTIONS ON CRUISE CON-
TROL
.If the cruise control system malfunc-
tions, it will cancel automatically. The
CRUISE indicator light on the meter
panel will then blink to warn the driver.
. If the engine coolant temperature
becomes excessively high, the cruise
control system will cancel automati-
cally.
. If the CRUISE indicator light blinks,
turn the cruise control main switch
off and have the system checked. It is
recommended you visit a NISSAN
dealer for this service.
. The CRUISE indicator light may blink
when the cruise control main switch is
turned ON while pushing the ACCEL/
RES, COAST/SET or CANCEL switch. To
properly set the cruise control system,
perform the following procedures.
WARNING
Do not use the cruise control when
driving under the following condi-
tions:
.when it is not possible to keep the
vehicle at a set speed .
in heavy traffic or in traffic that
varies in speed
. on winding or hilly roads
. on slippery roads (rain, snow, ice,
etc.)
. in very windy areas
Doing so could cause a loss of
vehicle control and result in an acci-
dent.
CAUTION
On manual transmission models, do
not shift into N (Neutral) without
depressing the clutch pedal when
the cruise control is set. Should this
occur, depress the clutch pedal and
turn the main switch off immedi-
ately. Failure to do so may cause
engine damage.
CRUISE CONTROL

5-24Starting and driving
To reset at a slower cruising speed,use
one of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed,
push the COAST/SET switch and re-
lease it.
. Push and hold the COAST/SET switch.
Release the switch when the vehicle
slows down to the desired speed.
. Push, then quickly release the COAST/
SETT switch. Each time you do this,
the set speed will decrease by about 1
MPH (1.6 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehi-
cle will resume 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 perfor-
mance and ensure the future relia-
bility and economy of your new
vehicle.
Failure to follow these recommenda-
tions may result in shortened engine
life and reduced engine perfor-
mance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. 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 possi-
ble. 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 andbrake application whenever possi-
ble.
.Maintain constant speed whilecommuting and coast whenever
possible.
2. Maintain constant speed.
.Look ahead to try and anticipate and minimize stops.
.Synchronizing your speed with traf-fic lights allows you to reduce your
number of stops.
.Maintaining a steady speed canminimize red light stops and im-
prove fuel efficiency.
3. Use air conditioning (A/C) at higher vehicle speeds.
.Below 40 MPH (64 km/h), it is moreefficient 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 aerody-
namic drag.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS

.Recirculating the cool air in thecabin when the A/C is on reduces
cooling load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h)
(where legally allowed) can improve
fuel efficiency due to reduced aero-
dynamic drag.
.Maintaining a safe following dis-tance behind other vehicles re-
duces unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to determine 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 cruis-
ing 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 morethan 30 seconds of idling at start-
up to effectively circulate the en-
gine oil before driving.
.Your vehicle will reach its ideal
operating temperature more
quickly while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, re-
sulting in reduced demand on your
A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-7).)

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.
. Never leave the engine running
while the vehicle is unattended.
. Do not leave children unattended
inside the vehicle. They could
unknowingly activate switches
or controls. Unattended children
could become involved in serious
accidents. .
To help avoid risk of injury or
death through unintended opera-
tion of the vehicle and/or its
systems, do not leave children,
people who require the assis-
tance of others or pets unat-
tended in your vehicle.
Additionally, the temperature in-
side a closed vehicle on a warm
day can quickly become high
enough to cause a significant risk
of injury or death to people and
pets.
. Safe parking procedures require
that both the parking brake be
applied and the transmission placed into P (Park) for Automatic
Transmission (AT) model or in an
appropriate gear for Manual
Transmission (MT) model. Failure
to do so could cause the vehicle
to move unexpectedly or roll
away and result in an accident.
. Make sure the automatic trans-
mission shift lever has been
pushed as far forward as it can
go and cannot be moved without
depressing the foot brake pedal.
1. Firmly apply the parking brake.
2. Automatic transmission models:
Move the shift lever to the P (Park)
position.
Manual transmission models:
Place the shift lever in the R (Reverse)
gear. When parking on an uphill grade,
place the shift lever in the 1st gear.
3. To help prevent the vehicle from roll- ing into the street when parked on a
sloping drive way, it is a good practice
to turn the wheels as illustrated.
.HEADED DOWNHILL WITH CURB:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
PARKING/PARKING ON HILLS

.HEADED UPHILL WITH CURB:
Turn the wheels away from the
curb and move the vehicle back
until the curb side wheel gently
touches the curb.
.HEADED UPHILL OR DOWNHILL, NOCURB:
Turn the wheels toward the side of
the road so the vehicle will move
away from the center of the road if
it moves.
4. Push the ignition switch to the OFF position.
WARNING
If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt
breaks, you will still have control of the
vehicle. However, much greater steering
effort is needed, especially in sharp turns
and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate
hydraulic circuits. If one circuit malfunc-
tions, you will still have braking at two
wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping dis-
tance will be longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one
side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake
pedal to heat-up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
