– When replacing tires, install thespecified 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 Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.

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 rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing 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 Anti-lock Braking System 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 Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(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 applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
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.
Starting and driving5-55

WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.The VDC system uses various sensors to
monitor driver inputs and vehicle motion.
Under certain driving conditions, the VDC
system helps to perform the following
functions:
∙ 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 control func-
tion).
∙ 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 fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations. When the VDC system operates, theindicator 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 indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip in-
dicator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system,
the
indicator light comes on in the
instrument panel. The VDC system auto-
matically turns off when these indicator
lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator and the
Automatic Emergency Braking (AEB) sys-
tem warning light illuminate to indicate the
VDC system is off.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-56Starting and driving
Page 323 of 435
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
indicator flashes if this oc-
curs. All other VDC functions are off and
the
indicator 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.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward or in reverse at a slow speed. When
the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
∙ The VDC system is designed to help the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully. ∙ Do not modif y the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the
indicator light may flash or
illuminate.
∙ If brake related parts such as brake pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and
the
indicator light may
illuminate.
∙ If engine control related parts are not NISSAN recommended or are ex-
tremely deteriorated, the
indi-
cator light may illuminate.
∙ When driving on extremely inclined surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or illuminate. Do not drive
on these types of roads. ∙ When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or illuminate. This is not a mal-
function. Restart the engine af ter
driving onto a stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the front and rear wheels
depending on the radius of the turn.

The chassis control is an electric control
module that includes the following func-
tions:∙ Intelligent Trace Control
∙ Intelligent Engine Brake
∙ Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response. The I–TC can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Chassis Control” page. For addi-
tional information, refer to “Vehicle infor-
mation display” in the “Instruments and
controls” section of this manual.
When the Vehicle Dynamic Control (VDC)
OFF switch is used to turn off the VDC sys-
tem, the I–TC is also turned off.
When the I–TC is operated and the Chassis
Control mode is selected in the vehicle in-
formation display, the I–TC graphics are
shown in the vehicle information display.
For additional information, refer to “Vehicleinformation display” in the “Instruments
and controls” section of this manual.
WARNING
The I–TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the I–TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I–TC is operating properly.
Even if the I–TC is set to OFF, some func-
tions will remain on to assist the driver (for
example, avoidance scenes).
INTELLIGENT ENGINE BRAKE (I-EB)
The I-EB function adds subtle deceleration
by controlling the Continuously Variable
Transmission gear ratio, depending on the
cornering condition calculated from driv-
er’s steering input and plural sensors. This
benefit is for easier traceability and less
workload of adjusting speed with braking
at corners.
The I-EB also adds subtle deceleration with
gear ratio control according to driver’s
brake pedal operation.

The I-EB can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Chassis Control” page. For addi-
tional information, refer to “Vehicle infor-
mation display” in the “Instruments and
controls” section of this manual.
When the I-EB is operated at corners and
the Chassis Control mode is selected in the
vehicle information display, the I-EB graph-
ics are shown in the vehicle information
display. For additional information, refer to
“Vehicle information display” in the “Instru-
ments and controls” section of this manual.
WARNING
The I-EB may not be effective depend-
ing on driving conditions. Always drive
carefully and attentively.
When the I-EB is operating, the needle of
the tachometer will rise up and you may
hear an engine noise. This is normal and
indicates that the I-EB is operating prop-
erly.
ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
based on wheel speed information and
controls four wheel brake pressure to en-
hance ride comfort in effort to restrain un-
comfortable upper body movement. This
system comes into effect above 25 mph
(40 km/h). When the VDC OFF switch is
used to turn off the VDC system, the ARC is
also turned off.
When the brake control of the ARC is oper-
ated and the Chassis Control mode is se-
lected in the vehicle information display,
the ARC graphics are shown in the vehicle
information display. For additional infor-
mation, refer to “Vehicle information dis-
play” in the “Instruments and controls” sec-
tion of this manual.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating properly.
WARNING
∙ Never rely solely on the hill start assist system to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. De-
press the brake pedal when the ve-
hicle is stopped on a steep hill. Be es-
pecially careful when stopped on a hill
on frozen or muddy roads. Failure to
prevent the vehicle from rolling back-
wards may result in a loss of control of
the vehicle and possible serious injury
or death.
∙ The hill start assist system is not de- signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and may
result in a collision or serious personal
injury.
∙ The hill start assist may not prevent the vehicle from rolling backwards on
a hill under all load or road conditions.
Always be prepared to depress the
brake pedal to prevent the vehicle
from rolling backwards. Failure to do
so may result in a collision or serious
personal injury.
HILL START ASSIST SYSTEM
5-60Starting and driving
Page 327 of 435
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the brake
pedal and apply the accelerator when the
vehicle is stopped on a hill.
The hill start assist system will operate au-
tomatically under the following conditions:∙ The transmission is shif ted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake.
The maximum holding time is 2 seconds.
Af ter 2 seconds the vehicle will begin to roll
back and the hill start assist system will
stop operating completely.
The hill start assist system will not operate
when the transmission is shif ted to the N
(Neutral) or P (Park) position or on a flat and
level road.
When the Vehicle Dynamic Control (VDC)
indicator light illuminates in the meter, the
hill start assist system will not operate. For
additional information, refer to “Vehicle Dy-
namic Control (VDC) indicator light” in the
“Instruments and controls” section of this
manual.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry function on the Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
anti-freeze, drain the cooling system, in-
cluding the engine block. Refill before oper-
ating the vehicle. For additional informa-
tion, refer to “Changing engine coolant” in
the “Do-it-yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded tires may be used. However,
some states, provinces and territories
prohibit their use. Check local laws be-
fore installing studded tires.
COLD WEATHER DRIVING
Starting and driving5-61
Page 328 of 435
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drif ts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid driv-
ing on wet ice until the road is salted
or sanded. ∙ Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steering
maneuvers.
∙ Do not use the cruise control on slip- pery roads.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
PARKING BRAKE
When parking in an area where the outside
temperature is below 32°F (0°C), do not ap-
ply the parking brake to prevent it from
freezing. For safe parking:
∙ Place the shif t lever in the P (Park) posi- tion.
∙ Securely block the wheels.
