BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking
force than a conventional 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 de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System
(ABS) is a sophisticated device,
but it cannot prevent accidents
resulting from careless or dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces even with ABS. Stopping
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 vehicle 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.
— When installing a spare tire, make sure that it is the proper
size and type as specified on
the Tire and Loading Informa-
tion label. See “Tire and Load-
ing Information label” (P.10-
10) of this manual.
— For detailed information, see “Wheels and tires” (P.8-29) of
this manual.
The Anti-lock Braking System (ABS) con-
trols the brakes so the wheels do not lock
during hard braking or when braking on
slippery surfaces. The system detects the
rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By pre- venting each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes.
The ABS will operate 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, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-

tion, it switches the ABS off and illumi-
nates 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. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 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 applies 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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following: .
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn
off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the off
position then back to the on position.

ing light” (P.2-15) and “Vehicle Dynamic

INTELLIGENT ENGINE BRAKE (Con-
tinuously Variable Transmission
(CVT) models)
The Intelligent Engine Brake function
adds subtle deceleration by controlling
CVT gear ratio, depending on the corner-
ing condition calculated from driver’s
steering input and plural sensors. This
benefit to easier traceability and less
workload of adjusting speed with braking
at corners.
The Intelligent Engine Brake also adds
subtle deceleration with gear ratio con-
trol according to driver’s brake pedal
operation.
The Intelligent Engine Brake can be set to
ON (enabled) or OFF (disabled) through
the Vehicle Information Display “Settings”
page. See “Vehicle information display”
(P.2-18) for more information.
JVS0403X
When the Intelligent Engine Brake is
operated at corners and the “Chassis
Control” mode is selected in the trip
computer, the Intelligent Engine Brake
graphics are shown in the vehicle infor-
mation display. See “Trip computer” (P.2-
34) for more information.
If the chassis control warning message
appears in the vehicle information dis-
play, it may indicate that the Intelligent
Engine Brake is not functioning properly.
Have the system checked as soon as
possible. It is recommended that you visit
a NISSAN dealer for this service.
WARNING
The Intelligent Engine Brake may not
be effective depending on the driv-
ing condition. Always drive carefully
and attentively.
When the Intelligent Engine Brake is
operating, the needle of the tachometer
will rise up and you may hear an engine
noise. This is normal and indicates that
the Intelligent Engine Brake is operating
properly.

. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction
of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instruc-
tions below.
Stopping the vehicle
1. Safely move the vehicle off the road
and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake.
4. Continuously Variable Transmission
(CVT) models:
Move the shift lever to the P (Park)
position.
Manual Transmission (MT) models:
Move the shift lever to the R (Reverse)
position.
5. Turn off the engine.
6. Raise the hood to warn other traffic, and to signal professional road assis-
tance personnel that you need assis-
tance. 7. Have all passengers get out of the
vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
.Make sure the parking brake is
securely applied and the Manual
Transmission is shifted into R
(Reverse), or the CVT into P (Park).
. Never change tires when the ve-
hicle is on a slope, ice or slippery
areas. This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle.
Wait for professional road assis-
tance.

Blocking wheels
Place suitable blocksat both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.
WARNING
Be sure to block the wheel as the
vehicle may move and result in
personal injury.

the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-7) of this manual for
wheel off-set dimensions.
. Since the spare tire is not
equipped with the TPMS, when a
spare tire is mounted or a wheel
is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 1 minute. The light
will remain on after 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as possible. It is recommended you
visit a NISSAN dealer for these
services.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning. .
The use of retread tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
All-Wheel Drive (AWD) models
CAUTION
.Always use tires of the same size,
brand, construction (bias, bias-
belted or radial), and tread pat-
tern on all four wheels. Failure to
do so may result in a circumfer-
ence difference between tires on
the front and rear axles which will
cause excessive tire wear and
may damage the transmission,
transfer case and rear differential
gears.
. Only use spare tires specified for
each AWD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
