2011 NISSAN FRONTIER ignition

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
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do 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
● Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants. ●
Keep 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.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do 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

subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:● The TPMS does not monitor the tire
pressure of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25
km/h) . Also, this system may not detect a
sudden drop in tire pressure (for example a
flat tire while driving) . ●
The low tire pressure warning light does not
automatically turn off when the tire pressure
of all 4 tires are adjusted. After the tires are
inflated to the recommended pressure, the
vehicle must be driven at speeds above 16
MPH (25 km/h) to activate the TPMS and
turn off the low tire pressure warning light.
Use a tire pressure gauge to check the tire
pressure.
● The CHECK TIRE PRES (pressure) warning
message is displayed in the odometer when
the low tire pressure warning light is illumi-
nated and low tire pressure is detected. The
CHECK TIRE PRES warning message turns
off when the low tire pressure warning light
turns off. Push the reset button for more than
1 second to manually turn off the CHECK
TIRE PRES warning message. The low tire
pressure warning light remains illuminated
until the tires are inflated to the recom-
mended COLD tire pressure. The CHECK
TIRE PRES warning message is displayed
each time the ignition switch is placed in the
ON position as long as the low tire pressure
warning light remains illuminated. See
“Check tire pressure warning message” in
the “Instruments and controls” section. ●
The CHECK TIRE PRES warning is not dis-
played if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
● The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire Pressure Monitoring System
(TPMS)” in the “In case of emergency” section.
5-4Starting and driving

WARNING
●Never remove the ignition key or place
the ignition switch in the LOCK position
while driving. The steering wheel will
lock (for models with a steering lock
mechanism) . This may cause the driver
to lose control of the vehicle and could
result in serious vehicle damage or per-
sonal injury.
AUTOMATIC TRANSMISSION (if so
equipped)
The ignition lock is designed so the ignition
switch cannot be placed in the LOCK position
and the key removed until the shift selector is
moved to the P (Park) position.
When removing the key from the ignition, make
sure the shift selector is in the P (Park) position.
If the shift selector is not returned to P (Park)
position, the ignition switch cannot be moved to
the LOCK position. To remove the key from the ignition switch:
1. Shift the shift selector to the P (Park) posi- tion with the ignition switch in the ON posi-
tion.
2. Place the ignition switch to the LOCK posi- tion.
3. Remove the key from the ignition.
If the shift selector is shifted to the P (Park)
position after the ignition switch is placed in the
OFF position or when the ignition switch cannot
be turned to the LOCK position, proceed as
follows to remove the key. 1. Move the shift selector into the P (Park) position.
2. Turn the ignition key slightly toward the ON position.
3. Turn the key to the LOCK position.
4. Remove the key.
The shift selector is designed so it cannot moved
out of P (Park) and into any of the other gear
positions if the ignition key is turned to OFF

Starting and driving5-11

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.

AUTOMATIC TRANSMISSION (if so
equipped)
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) , 3, 2 or 1.
Always depress the brake pedal until
shifting is completed. Failure to do so
could cause you to lose control and
have an accident.
● Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
● Never shift to P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
CAUTION
● When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brake should be used for this purpose.
● Do not downshift abruptly on slippery
roads. This may cause a loss of control. The automatic transmission in your vehicle is
electronically controlled to produce maximum
power and smooth operation.
The recommended operating procedures for this
transmission are shown on the following pages.
