2020 NISSAN FRONTIER check engine

3. Try to rearrange the trailer load so it isbalanced as described in this section.
• Be careful when passing other vehicles. Passing while towing a trailer requires
considerably more distance than normal
passing. Remember, the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
• Downshif t the transmission to a lower gear for engine braking when driving
down steep or long hills. This will help
slow the vehicle without applying the
brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control not be used while towing a trailer.
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits. • Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more fre-
quently. For additional information, refer
to the “Do-it-yourself ” section in this
manual.FLAT TOWING – 4WD WITH
AUTOMATIC TRANSMISSION
Towing a vehicle behind a recreational ve-
hicle, such as a motor home, is sometimes
called flat towing.
CAUTION
• DO NOT flat tow a 4WD vehicle
equipped with an automatic trans-
mission. Flat towing or using a ve-
hicle dolly WILL DAMAGE internal
transmission parts due to lack of
lubrication.
• For emergency towing procedures
refer to “Towing recommended by
NISSAN” in the “In case of emer-
gency ” section of this manual.
10-36Technical and consumer information

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested us-
ing a two wheel dynamometer (such as
the dynamometers used by some
states for emissions testing), or similar
equipment. Make sure you inform the
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 transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready ” condi-
tion. Before taking the I/M test, check the
vehicle's inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready ”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
