be towed with all f our wheels on the
ground, do the f ollowing:Release the parking brake.
Start the engine.
Shif t to D f or several seconds,
then to N.
Turn of f the engine. With all f our wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inf orm
them a f lat-bed is required.
Emergency Towing
The only way you can saf ely tow
your vehicle is with f lat-bed
equipment.

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine, your vehicle must be
transported with the all f our wheels of f
the ground. The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns f reely bef ore you begin
towing.
Towing your vehicle with two tires on
the ground will damage parts of the
4WD system. It should be transported
on a f lat-bed truck or trailer. Trying to lif t or tow your vehicle by the

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our 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 f rom the crankcase and
evaporative emissions control
systems.
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)
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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.
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 emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
