2011 NISSAN FRONTIER check engine

If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedures:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position, and wait approximately 10 sec-
onds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake and clutch fluid (if so equipped) ,
and windshield-washer fluid as frequently as
possible, or at least whenever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Check that all doors are closed.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten the seat belt and ask all passengers
to do likewise.
● Check the operation of warning lights when
the key is turned to the ON (3) position. See
“Warning/indicator lights and audible re-
minders” in the “Instruments and controls”
section of this manual. 1. Apply the parking brake.
2.
Automatic transmission:
Move the shift selector to P (Park) or N
(Neutral) . P (Park) is recommended.
The shift selector cannot be moved out
of the P (Park) position and into any of
the other gear positions if the ignition
switch is placed in the OFF position or
if the key is removed from the ignition
switch.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
Manual transmission:
Move the shift selector to N (Neutral) . De-
press the clutch pedal to the floor while
cranking the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Crank the engine with your foot off the
accelerator pedal by placing the ignition
switch in the START position. Release the
key when the engine starts. If the engine
starts, but fails to run, repeat the above
procedure.

WARNING
●For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
CAUTION
● Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position for automatic transmission vehicles, stop the ve-
hicle and shift the shift selector to
the N position with the brake pedal
depressed and shift the 4WD shift
switch to 2WD.
– in the 4LO position for manual trans- mission vehicles, stop the vehicle
and shift the shift selector to the N
position with the clutch pedal de-
pressed and shift the 4WD shift
switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
USING FOUR WHEEL DRIVE
(4WD) (if so equipped)
Starting and driving5-23

*1: Before moving the shift selector from neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedure is completedand the transfer gear is correctly set in the 4LO position. If the vehicle is shifted into gear before the indicator is on steady, the transfer gear may grind,
not engage correctly or stay in the neutral position.
- If the 4WD warning light illuminates, perform the following procedure to return the transfer case to correct operating condition.
1. Turn off the engine by turning the ignition switch OFF.
2. Start the engine.
- Check that the 4WD warning light turns off. If the 4WD warning light illuminates, have the system checked by a NISSAN dealer.
3. Apply the parking brake, for automatic transmission vehicles, depress the brake pedal and move the shift selector to Neutral position. For manual transmission vehicles, move the shift selector to Neutral position.
4. With the brake pedal depressed on automatic transmission vehicles or with the clutch pedal depressed on manual transmission vehicles, move the 4WD shift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the shift selector from Neutral position.
*2: While changing in and out of 4LO, the ignition key must be ON and the vehicle’s engine must be running for a shift to take place and for the indicator lights (4WD shift and 4LO position indicator) to be operable. Otherwise, the shift will not take place and no indicator lights will be on or flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shift the 4WD shift switch to 4LO. The
indicator light (if so equipped) will
also turn on when 4LO is selected. See “Vehicle Dynamic Control (VDC) system” later in this section.

4WD shift indicator light
The 4WD shift indicator light is located in the
odometer display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.● The 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on. ●
If the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
If the 4WD shift indicator light indication
changes to 2WD when the 4WD shift
switch is shifted to the 4H position at low
ambient temperatures, the 2WD mode
may be being engaged due to malfunc-
tioning drive system. If the indicator does
not return to normal and the 4WD warning
light comes on, have the system checked
by the nearest NISSAN dealer.
4WD warning light
Warning light Comes on or blinks
when:
Comes on There is a mal-
function in the4–wheel drive system
Blinks
slowly The difference in
wheel rotation is large
The 4WD warning light is located in the meter. The 4WD warning light comes on when the igni-
tion switch is turned to ON. It turns off soon after
the engine is started.
If any malfunction occurs in the 4WD system
when the ignition switch is ON, the warning light
will either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
●
If the warning light comes on or blinks
slowly during operation, have your ve-
hicle checked by a NISSAN dealer as
soon as possible.
● Shifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.

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.

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 toprovide 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:
● A scraper and stiff-bristled brush to remove
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 snowdrifts.
● 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” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.

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, and the CHECK
TIRE PRES (pressure) warning message is dis-
played in the odometer, 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 activate only when
the vehicle is driven at speeds above 16 MPH
(25 km/h) . For more details, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, and
“Tire Pressure Monitoring System (TPMS)” in the
“Starting and driving” section.
WARNING
●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 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.
● 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.
