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

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. For additional information, refer
to “Malfunction Indicator Light (MIL)” in the
“Instruments and controls” section of this
manual. 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 notreturn 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) .

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
(805 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 effi-
cient to open windows to cool the vehicle
due to reduced engine load
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-26Starting and driving

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
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 pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best braking
performance. This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels.
BRAKE SYSTEM
5-30Starting and driving

– When installing a spare tire, makesure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to the ”Tire and load-
ing information label” in the “Techni-
cal and consumer information”
section of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes 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
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates 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 ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation 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 operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional 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 driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
