Inst rument s and Cont rols
2013 TL

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
If your vehicle has an automatic
transmission, set the parking
brake before you put the
transmission in Park. This keeps
the vehicle from moving and
putting pressure on the parking
mechanism in the transmission.Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Lock the doors.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire. Check the indicator on the
instrument panel to verif y that the
security system is set.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb. If your vehicle has a manual
transmission, put it in f irst gear.If the vehicle is f acing downhill,
turn the front wheels toward the
curb. If your vehicle has a manual
transmission, put it in reverse gear.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
If you are unable to stop the
engine normally when the vehicle is
parked (in the Park position on the
automatic transmission models), see on

The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way
catalytic converter. These four
systems work together to control
the engine’s combustion and
minimize the amount of HC, CO,
and NOx that come out the tailpipe.
The exhaust emissions control
systems are separate from the
crankcase and evaporative
emissions control systems.The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate
from the rest of your vehicle.
Read your warranty manual for
more information.
The PGM-FI system uses sequential
multiport f uel injection. It has three
subsystems: air intake, engine
control, and f uel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. It then controls how much f uel to inject
under all operating conditions.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor. The exhaust gas recirculation
(EGR) system takes some of the
exhaust gas and routes it back
into the intake manifold. Adding
exhaust gas to the air/fuel mixture
reduces the amount of NOx
produced when the fuel is burned. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.

Technical Inf ormation
2013 TL

The three way catalytic converters
contain precious metals that serve as
catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converters are ref erred
to as three-way catalysts, since they
act on HC, CO, and NOx.
Replacement units must be original
Acura parts or their equivalent.
The three way catalytic converters
must operate at a high temperature
for the chemical reactions to take
place. They can set on fire any
combustible materials that come
near them. Park your vehicle away
from high grass, dry leaves, or
other flammables.Defectivethreewaycatalytic
converters contribute to air pollution,
and can impair your engine’s
perf ormance. Follow these
guidelines to protect your vehicle’s
three way catalytic converters.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the
three way catalytic converters
ineffective. Keep the engine well maintained.
Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly.
