3. AEB system warning light
AEB SYSTEM OPERATION
The AEB system will function when your
vehicle is driven at speeds above approxi-
mately 3 mph (5 km/h).
If a risk of a forward collision is detected,
the AEB system will provide an initial warn-
ing to the driver by both a visual (yellow)
and audible alert.
If the driver applies the brakes quickly and
forcefully af ter the warning, and the AEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force. If
the driver does not take action, the AEB
system issues the second visual warning
(red) and audible warning and also applies
partial braking.
If the risk of a collision becomes imminent,
the AEB system applies harder braking au-
tomatically.

NOTE:
The vehicle’s brake lights come on when
braking is performed by the AEB system.
Depending on vehicle speed and distance
to the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences of a colli-
sion, should one be unavoidable. If the
driver is handling the steering wheel, accel-
erating or braking, the AEB system will
function later or will not function.
The automatic braking will cease under the
following conditions:∙ When the steering wheel is turned as far as necessary to avoid a collision.
∙ When the accelerator pedal is de- pressed.
∙ When there is no longer a vehicle de- tected ahead.
If the AEB system has stopped the vehicle,
the vehicle will remain at a standstill for
approximately 2 seconds before the
brakes are released.

AEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The AEB system cannot detect all ve- hicles under all conditions.
∙ The radar sensor does not detect the following objects:
– Pedestrians, animals or obstacles in the roadway.
– Oncoming vehicles.
– Crossing vehicles.
∙ The radar sensor has some perfor- mance limitations. If a stationary ve-
hicle is in the vehicle’s path, the AEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h).
∙ The radar sensor may not detect a ve- hicle ahead in the following
conditions:
– Dirt, ice, snow or other material covering the radar sensor. – Interference by other radar
sources.
– Snow or road spray from traveling vehicles.
– If the vehicle ahead is narrow (e.g., motorcycle).
– When driving on a steep downhill slope or roads with sharp curves.
∙
In some road or traffic conditions, the
AEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the ac-
celerator pedal to override the system.
∙ Braking distances increase on slip- pery surfaces.
∙
The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstructions of
the sensor area such as ice, snow, stick-
ers, etc. In these cases, the system may
not be able to warn the driver properly.
Be sure that you check, clean and clear
the sensor area regularly.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.

During the first 1,200 miles (2,000 km),
follow these recommendations to ob-
tain maximum engine performance
and ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.
∙ Avoid driving for long periods at con- stant 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 pos- sible. 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 com- muting and coast whenever possible
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops
∙ Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
5-68Starting and driving

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 exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes
∙ Select a gear range suitable to road conditions 5.
Use Cruise Control
∙ Using cruise control during highway driving 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 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 more than 30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving
∙ Your vehicle will reach its ideal oper- ating temperature more quickly
while driving versus idling
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem
11. ECO Mode
∙ The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable
Transmission (if so equipped) opera-
tion automatically to avoid rapid ac-
celeration.
Starting and driving5-69

∙ Keep your engine tuned up.
∙ Follow the recommended scheduledmaintenance.
∙ 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 engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.
WARNING
∙ Do not stop or park the vehicle overflammable 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 in P (Park) for
Continuously Variable Transmission
(CVT) models or in an appropriate
gear for manual transmission (M/T)
models. Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the shif t 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 whilethe vehicle is unattended.
∙ To help avoid risk of injury or death through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
1. Firmly apply the parking brake.
2. M/T models
Place the shif t lever in the R (Reverse)
position. When parking on an uphill
grade, place the shif t lever in 1st gear.
CVT models
Move the shif t lever into the P (Park)
position. 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.
∙ HEADED UPHILL OR DOWNHILL, NO CURB
3:
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. Place the ignition switch in the LOCK position and remove the key.
WARNING
∙ If the engine is not running or isturned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate.
∙ When the power steering warning light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
The power steering system is designed to
provide power assist while driving to oper-
ate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. When the temperature of the
power steering system goes down, the
power assist level will return to normal.
Avoid repeating such steering wheel op-

erations that could cause the power steer-
ing system to overheat.
You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, there will
be no power assist for the steering, but you
will still have control of the vehicle. At this
time, greater steering effort is required to
operate the steering wheel, especially in
sharp turns and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.The brake system has two separate hy-
draulic 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 pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance 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 downshif t 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
downshif ting. Abrupt braking or ac-
celerating 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 as-
sist for the brakes will not work. Brak-
ing 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 lon-
ger 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 stopping effect of the parking brake is
weakened or whenever the parking brake
