engine NISSAN FRONTIER 2009 Owner´s Manual

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.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
cWhile 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.
cIf 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
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake performance.

manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
cThe 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.
cTire 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) .

When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
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 oper-
ating. 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 required while driving.cABLS is a form of traction control using
sensors from the Anti-lock Brake System
(ABS) to transfer power from a slipping drive
wheel to a wheel with more traction. The
ABLS system applies braking to the slipping
wheel, which helps redirect power to an-
other wheel.
cOn 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system will operate for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
cThe ABLS system is always ON unless the
system detects brake pad overheating. If
high brake pad temperature is detected, it
will turn OFF, but normal brake function will
continue. ABLS will function even when the
VDC system is turned OFF.
WARNING
The ABLS system provides increased trac-
tion, but will not prevent accidents due to
abrupt steering operation or by careless
driving or dangerous driving practices.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces, and always drive
carefully.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.
cWhen the Vehicle Dynamic Control (VDC)
system is operating, the SLIP indicator in the
instrument panel blinks.
cIf the 4WD transfer case is shifted into 4LO
the
indicator light will come on and
the VDC system will be turned off. See
“Transfer case shifting procedures” earlier in
this section.
cIf the SLIP indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “In-
struments and controls” section.
If the battery is removed or discharged, the trac-
tion control system may be disabled and the
SLIPand
indicator lights will not turn off
after 2 seconds when the ignition switch is turned
to the ON position. Perform the following proce-
dure to reset the system:
cStart the engine and set the steering wheel
in the straight forward position.

cDrive the vehicle at speeds above 10 mph
(15 km/h) for at least 10 minutes.
cThe VDC OFF indicator light should go off
indicating the traction control system is op-
erational.
cIf you interrupt the reset procedure by turn-
ing the ignition off, you will need to restart
the reset procedure.
If after driving the vehicle for more than 10 min-
utes and theSLIPand
lights remain illumi-
nated in the instrument panel, have the Vehicle
Dynamic Control system checked by a NISSAN
dealer.
If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, most VDC and Traction Control System
(TCS) functions will be turned off. TheSLIP
indicator will flash if wheel spin is detected. The
ABS will still operate with the VDC system off.
When the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
vibration from under the hood. This is not a mal-
function and indicates that the VDC system is
working properly.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
cThe Vehicle Dynamic Control system is
designed to help improve driving stabil-
ity 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 sur-
faces and always drive carefully.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
approved for your vehicle or are ex-
tremely deteriorated the Vehicle Dy-
namic Control system may not operate
properly. This could adversely affect ve-
hicle handling performance, and the
VDC OFF indicator light may come on.cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Vehicle Dynamic Control
system may not operate properly and
the Vehicle Dynamic Control OFF indi-
cator light may come on.
cIf engine related parts such as muffler
are not standard equipment or are ex-
tremely deteriorated, the “VDC OFF” in-
dicator or “SLIP” indicator or both indi-
cator lights may illuminate.
cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the Vehicle Dynamic Control system
may not operate properly and the VDC
OFF indicator light may come on. Do
not drive on these types of roads.
cWhen driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the Vehicle Dynamic Control off
indicator light may illuminate. This is
not a malfunction. Restart the engine
after driving onto a stable surface.

cIf wheels or tires other than the recom-
mended ones are used, the Vehicle Dy-
namic Control system may not operate
properly and the Vehicle Dynamic Con-
trol off indicator light may come on.
cThe Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.WARNING
cNever rely solely on the hill descent
control system to control vehicle speed
when driving on steep down hill 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 an 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.
cThe 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 re-
sult 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.
cWhen 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.
cOnce the system is activated the indicator
light will remain on in the instrument panel,
see “Hill descent control system on indicator
light” in the “Instruments and controls” sec-
tion.
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 selector lever in 2 (Second
gear) or 1 (Low gear) for engine braking.

WARNING
cNever 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
vehicle from rolling backwards may re-
sult in a loss of control of the vehicle
and possible serious injury or death.
cThe 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.
cThe 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:
cThe selector lever is shifted to a forward or
reverse gear.
cThe 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
selector is shifted to N or P or on a flat and level
road.
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 inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and 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 maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.3. Tire chains may be used. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
cA sturdy, flat board to be placed under the
jack to give it firm support.
cA shovel to dig the vehicle out of snowdrifts.
cExtra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet 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” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.cWhatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
cAllow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.
cWatch 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.
cDo not use the cruise control on slip-
pery roads.
cSnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. If the
vehicle is being driven with low tire pressure, the
TPMS will activate and warn you of it by the low
tire pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 MPH (25 km/h) . For more details, refer
to “Warning/indicator lights and audible remind-
ers” in the “Instruments and controls” section,
and “Tire Pressure Monitoring System (TPMS)”
in the “Starting and driving” section.
WARNING
cIf 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 acci-
dent and could result in serious per-
sonal injury. 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.
cWhen 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.cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
cDo 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.

ing plate on the wheel and then lift the
spare tire.
Jacking up vehicle and removing the
damaged tire
WARNING
cNever get under the vehicle while it is
supported only by the jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cUse only the jack provided with your
vehicle to lift the vehicle. Do not use the
jack provided with your vehicle on other
vehicles. The jack is designed for lifting
only your vehicle during a tire change.
cUse the correct jack-up points. Never
use any other part of the vehicle for jack
support.
cNever jack up the vehicle more than
necessary.cNever use blocks on or under the jack.
cDo not start or run the engine while
vehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
cDo not allow passengers to stay in the
vehicle while it is on the jack.
cNever run the engine with a wheel(s) off
the ground. It may cause the vehicle to
move.
Always refer to the illustration for the correct
placement and jack-up points for your specific
vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.
1. Loosen each wheel nut one or two turns by
turning counterclockwise with the wheel nut
wrench.Do not remove the wheel nuts
until the tire is off the ground.
