This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 respon-
sible 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
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (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 slip-
pery 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.
Starting and driving5-35

When the ABS senses that 1 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.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.●
ABLS system uses automatic braking to
transfer power from a slipping drive wheel to
the wheel on the same axle with more trac-
tion. The ABLS system applies braking to
the slipping wheel, which helps redirect
power to the other wheel.
● On 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system operates for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
● The ABLS system is always ON. In some
conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake func-
tion will continue. ABLS will function even
when the VDC system is turned OFF.
● The ABLS does not operate if both wheels
on a drive axle are slipping.WARNING
● The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering opera-
tion or by careless driving or dangerous
driving practices. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces. Al-
ways drive carefully.
●
Do not modify the vehicle’s suspension. If
suspension parts such as shock absorb-
ers, struts, springs, stabilizer bars, bush-
ings and wheels are not NISSAN ap-
proved for your vehicle or are extremely
deteriorated, the ABLS system may not
operate properly. This could adversely af-
fect vehicle handling performance, and
the slip indicator light may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the ABLS system may not
operate properly and the slip indicator
light may illuminate.
● If wheels or tires other than the NISSAN
recommended ones are used, the ABLS
system may not operate properly and
the slip indicator light may illuminate.
ACTIVE BRAKE LIMITED SLIP (ABLS)
SYSTEM
5-36Starting and driving

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle 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 function) .
● If the 4WD transfer case is shifted into 4LO
the
indicator light will come on and
the VDC system will be turned off. See “Us-
ing four wheel drive (4WD)” earlier in this
section.
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing 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 cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the
indi-
cator 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.
See “Slip indicator light” and ”Vehicle Dynamic
Control (VDC) OFF indicator light” in the ”Instru-
ments and controls” section.
If a malfunction occurs in the system, the
indicator light will come on in the instrument
panel. The VDC system automatically turns off
when these indicator lights are off.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate 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
indicator flashes if this occurs. 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 feature
that tests the system each time you start the
engine and move the vehicle forward 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
indication of a malfunction.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
Starting and driving5-37

●Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer 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 per-
formance, and the
indicator may
flash or the
indicator light may
illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the VDC system may not
operate properly and the
indica-
tor light may illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, the
indicator light
may illuminate.
● When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
the
indicator light may 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 may flash or
the
indicator light may illuminate.
This is not a malfunction. Restart the
engine after 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 may flash or
the
indicator light may illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
WARNING
● Never rely solely on the hill descent
control system to control vehicle speed
when driving on steep downhill grades.
Always drive carefully and attentively
when using the hill descent control sys-
tem and decelerate the vehicle speed by
depressing the brake pedal if neces-
sary. Be especially careful when driving
on frozen, muddy or extremely steep
downhill roads. Failure to control ve-
hicle speed may result in a loss of con-
trol of the vehicle and possible serious
injury or death.
●
The hill descent control may not control
the vehicle speed on a hill under all load
or road conditions. Always be prepared
to depress the brake pedal to control
vehicle speed. Failure to do so may result
in a collision or serious personal injury.
The hill descent control system helps maintain
vehicle speed when driving under 15-21 MPH
(25-35 km/h) on steeper downhill grades. Hill
descent control is useful when engine braking
alone in 4H or 4L cannot control vehicle speed.
Hill descent control applies the vehicle brakes to
control vehicle speed allowing the driver to con-
centrate on steering while reducing the burden of
brake and accelerator operation.
HILL DESCENT CONTROL SYSTEM (if
so equipped)
5-38Starting and driving

●When additional braking is required on
steep downhill roads, activate the hill de-
scent control system by pushing the switch
ON. See “Hill descent control switch” in the
“Instruments and controls” section.
● Once the system is activated, the indicator
light will remain on in the instrument panel.
See “Hill descent control system on indica-
tor light” in the “Instruments and controls”
section.
If the accelerator or brake pedal is depressed
while the hill descent control system is on, the
system will stop operating temporarily. As soon
as the accelerator or brake pedal is released, the
hill descent control system begins to function
again if the hill descent control operating condi-
tions are fulfilled.
For the best results, when descending steep
downhill grades, the hill descent control switch
should be ON and the shift lever in 2 (Second
gear) or 1 (Low gear) for engine braking.WARNING
● Never rely solely on the hill start assist
system to prevent the vehicle from mov-
ing backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is stopped
on a steep hill. Be especially careful
when stopped on a hill on frozen or
muddy roads. Failure to prevent the ve-
hicle from rolling backwards 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 standstill
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. Al-
ways 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. 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.
Hill start assist will operate automatically under
the following conditions:
● The shift lever is shifted 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. After
2 seconds the vehicle will begin to roll back and
hill start assist will stop operating completely.
Hill start assist will not operate when the shift
lever is shifted into N (Neutral) or P (Park) or on a
flat and level road.
HILL START ASSIST SYSTEM (if so
equipped)
Starting and driving5-39

●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 reach-
ing 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.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist with cold
temperature starting.
The engine block heater should be used when
the outside temperature is 20°F (-7°C) or lower.
WARNING
● Do not use your engine block heater
with an ungrounded electrical system or
a 2-pronged adapter. You can be seri-
ously injured by an electrical shock if
you use an ungrounded connection.
● Disconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
● Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal
injury. To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and prop- erly store the cord to keep it away from
moving parts.
5-42Starting and driving

●If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal in-
jury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
● 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 approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting. ●
Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● 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 instructions be-
low:
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. Shift the manual transmission into R
(Reverse) , or the automatic transmission
into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. 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 auto-
matic transmission into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
6-4In case of emergency

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal
injury.1. If the booster battery is in another vehicle, position the two vehicles to bring their bat-
teries near each other.
Do not allow the two vehicles to touch. 2. Apply the parking brake. Move the shift lever
to N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) . Switch off
all unnecessary electrical systems (lights,
heater, air conditioner, etc.) .
3. Remove vent caps on the battery (if so equipped) . Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence il- lustrated (
A,B,C,D).
CAUTION
●Always connect positive () to positive
() and negative () to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
● Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
5. Start the engine of the booster vehicle and let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm, and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, turn the key off and
wait 3 to 4 seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.
8. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.

6-12In case of emergency

CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Automatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
● For manual transmission models, never
try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
WARNING
● Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
● To avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect abnormal
noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and move the shift lever to
N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) . Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-13

TOWING RECOMMENDED BY
NISSAN
Two-wheel drive models
NISSAN recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flatbed truck as illustrated.
CAUTION
●Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward) , as this may
cause serious and expensive damage to
the transmission. If it is necessary to
tow the vehicle with the front wheels
raised always use towing dollies under
the rear wheels.
● When towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies: – Place the ignition switch in the OFF
position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with a
steering lock mechanism) .
● If you have to tow manual transmission
models with the rear wheels on the
ground (if you do not use towing dol-
lies) or four wheels on the ground:
● Always release the parking brake.
● Move the transmission shift lever to
the N (Neutral) position
● Observe the following restricted tow-
ing speeds and distances for manual
transmission models only:
Speed: Below 60 MPH (97 km/h)
Distance: Less than 500 miles
(805 km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before towing
to prevent damage to the transmission.
