1999 NISSAN FRONTIER check engine light

WARNING
IInfants and small children should
always be placed in an appropriate
child restraint while riding in the ve-
hicle. Failure to use a child restraint
can result in serious injury or death.
IChildren and infants should never be
carried on your lap. It is not possible
for even the strongest adult to resist
the forces of a severe accident. The
child could be crushed between the
adult and parts of the vehicle. Also,
do not put the same seat belt around
both your child and yourself.INever install a rear-facing child re-
straint in the front seat, unless the
passenger supplemental air bag is
OFF. Be sure to turn the passenger
supplemental air bag ON/OFF switch
OFF. An inflating air bag could seri-
ously injure or kill your child. See
``Passenger supplemental air bag
ON/OFF switch and light'' earlier in
this section.
IAn improperly installed child re-
straint could lead to serious injury or
death in an accident.
IIn general, child restraints are de-
signed to be installed with a lap belt
or the lap portion of a three-point
type seat belt.
Child restraints for infants and small chil-
dren of various sizes are offered by several
manufacturers. When selecting any child
restraint, keep the following points in mind:
1) Choose only a restraint with a label cer-
tifying that it complies with Federal Motor
Vehicle Safety Standard 213 or Cana-
dian Motor Vehicle Safety Standard 213.
2) Check the child restraint in your vehicle
to be sure it is compatible with the vehi-cle's seat and seat belt system. Choose
a child restraint that meets the guidelines
of the Society of Automotive Engineers
recommended practice J1819 for child
restraint installation.
3) If the child restraint is compatible with
your vehicle, place your child in the child
restraint and check the various adjust-
ments to be sure the child restraint is
compatible with your child. Always follow
all of the recommended procedures.
All U.S. states and provinces of Canada
require that infants and small children be
restrained in an approved child restraint
at all times while the vehicle is being
operated.
WARNING
IDo not install a child restraint in the
jump seats (King Cab model). These
seats are not suitable for child re-
straint installation.
IDo not install a child restraint in the
center position of the front bench
seat. This position is not suitable for
child restraint installation.

ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise have your vehicle towed.
IPressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stop-
ping distance and require greater
pedal effort as well as pedal travel.

mark on the brake fluid reservoir, do
not drive until the brake system has
been checked at an authorized NIS-
SAN dealer.

This light indicates that the automatic trans-
mission parking function is not engaged. If
the transfer control is not secured in any
drive position while the automatic transmis-
sion selector lever is in the P position, the

4L position when the warning light comes
on.
IWhen parking, always make sure that the
transfer lever is in H or 4L and the
parking brake is set.
IIf the ATP light is ON, this indicates that
the automatic transmission P position will
not function and the transfer lever is in N

lever in H or 4L could result in the vehicle
moving unexpectedly, resulting in serious
personal injury or property damage.
Automatic transmission oil
temperature warning light
(
model)
This light comes on when the automatic
transmission oil temperature is too high. If
the light comes on while driving, reduce the

sound when the vehicle is in motion whether
or not the brake pedal is depressed. Have
the brakes checked as soon as possible if
the warning sound is heard.

emission control system malfunction has
been detected. Have the vehicle in-
spected by an authorized NISSAN
dealer. You do not need to have your
vehicle towed to the dealer.
IMalfunction indicator light blinking þ An
engine misfire has been detected which
may damage the emission control sys-
tem. To reduce or avoid emission control
system damage:
Ido not drive at speeds above 45 MPH
(72 km/h).
