2003 NISSAN FRONTIER check engine

Your new NISSAN is the result of our dedication to
produce the finest in safe, reliable and economical
transportation. Your vehicle is the product of a suc-
cessful worldwide company that manufactures cars
and trucks in over 17 countries and distributes them
in 170 nations.
NISSAN vehicles are designed and manufactured
by Nissan Motor Co., Ltd. which was founded in
Tokyo, Japan in 1933, and NISSAN affiliates world-
wide, collectively growing to become the fifth largest
automaker in the world. In addition to cars and
trucks, NISSAN also makes forklift trucks, marine
engines, boats and other diversified products.
NISSAN has made a substantial and growing in-
vestment in North America. NISSAN’s commitment
is over $6 billion dollars in capital investments in
facilities across the continent. Some of the facilities
include the Nissan Manufacturing facility in Smyrna,
Tennessee, vehicle styling design at Nissan DesignAmerica, Inc. in San Diego, California, and engineer-
ing at Nissan Technical Center North America in
Farmington Hills, Michigan. Additionally, NISSAN
employs nearly 19,000 people throughout the
United States, Canada, and Mexico. An additional
60,000 people work for the 1,250 NISSAN and
INFINITI dealers across North America.
NISSAN is also a substantial contributor to the
Canadian economy. Nissan Canada Inc., its suppli-
ers and over 150 dealers employ approximately
4,500 people. These include company employees
and the staffs of NISSAN dealers all across Canada.
In addition, many Canadians work for companies
that supply NISSAN and NISSAN dealers with ma-
terials and services ranging from the operation of
port facilities and transportation services, to the
supply of lubricants, parts and accessories.
NISSAN pioneered the use of electronics and com-
puters in automobiles, and has led the industry inimproving both performance and fuel efficiency
through new engine designs and the use of syn-
thetic materials to reduce vehicle weight. The com-
pany has also developed ways to build quality into its
vehicles at each stage of the production process,
both through extensive use of automation and —
most importantly — through an awareness that
people
are the central element in quality control.
From the time the parts arrived from our suppliers
until you took delivery of your new NISSAN, dozens
of checks were made to ensure that only the best job
was being done in producing and delivering your
vehicle. NISSAN also takes great care to ensure that
when you take your NISSAN to your dealer for
maintenance, the service technician will perform his
work according to the quality standards that have
been established by NISSAN.
Safety has also been built into your NISSAN. As you
know, seat belts are an integral part of the safety
systems that will help protect you and your passen-
gers in the event of a sudden stop or an accident.
We urge you to use the seat belts every time you
drive the vehicle.
The NISSAN story of growth and achievement re-
flects our major goal: to provide you, our customer,
with a vehicle that is built with quality and craftsman-
ship — a product that we can be proud to build and
you can be proud to own.

soon as safely possible until the light turns off.
CAUTION
Continued vehicle operation when the A/T
oil temperature warning light is on may
damage the automatic transmission.
Automatic transmission park

model)
This light indicates that the automatic transmis-
sion parking function is not engaged. If the trans-
fer control shift lever is not secured in any drive
position while the automatic transmission selec-
tor lever is in the P (Park) position, the vehicle
