engine NISSAN FRONTIER 2010 Owner´s Manual

THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo not push or tow your vehicle to start
the engine.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
all 4 tires to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
Starting and driving5-3

cMany hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
cDo not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
cStay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
cIf your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear. Never
back down in N (Neutral) or with the
clutch depressed (manual transmission
vehicles) , using only the brake, as this
could cause loss of control.
cHeavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed. Use the hill
descent control feature (if so
equipped) .cUnsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
cTo avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as pos-
sible. Do not equip the vehicle with tires
larger than specified in this manual.
This could cause your vehicle to roll
over.
cDo not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
cBefore operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
cAlways drive with the floor mats in
place as the floor may become hot.cLower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
cDo not drive beyond the performance
capability of the tires, even with 4WD
engaged.
cFor 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.

MANUAL TRANSMISSION (if so
equipped)
The ignition switch includes a device that helps
prevent accidental removal of the key while driv-
ing.
The key can only be removed when the ignition
switch is in the LOCK position.
On manual transmission models, to turn the igni-
tion switch to the LOCK position from the ACC or
ON position, place the ignition switch in the OFF
position, push the key in, then place the ignition
switch in LOCK position.
KEY POSITIONS
LOCK: Normal parking position (0)
OFF: (Not used) (1)
ACC: (Accessories) (2)
This position activates electrical accessories
such as the radio when the engine is not running.
ON: Normal operating position (3)
This position turns on the ignition system and the
electrical accessories.
START: (4)
This position starts the engine. As soon as the
engine has started, release the key. It automati-
cally returns to the ON position.
NISSAN VEHICLE IMMOBILIZER
SYSTEM (if so equipped)
The NISSAN Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
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.

WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
