2010 NISSAN FRONTIER check engine

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.
5-38Starting and driving

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.

CAUTION
cDo not push start this vehicle. The
three-way catalyst may be damaged.
cAutomatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
cFor 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
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo 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.
cDo 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 selector
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 emergency6-11

6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors are generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to your
vehicle, NISSAN recommends having a service
operator tow your vehicle. It is advisable to have
the service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it has
been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any of these conditions apply, dollies or
a flatbed tow truck must be used.
cAlways attach safety chains before
towing.For information about towing your vehicle behind
a recreational vehicle (RV) , refer to “Flat towing”
in the “Technical and consumer information” sec-
tion of this manual.

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money.
However, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition, as well as its emis-
sions and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hiclesbeforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hoodCheck that the doors
and engine hood operate properly. Also ensure
that all latches lock securely. Lubricate hinges,
latches, latch pins, rollers and links as necessary.
Make sure that the secondary latch keeps the
hood from opening when the primary latch is
released.
MAINTENANCE REQUIREMENTS GENERAL MAINTENANCE
8-2Maintenance and do-it-yourself

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
