Traction Control System

TCS ON/OFF Switch
This switch is under the side vent. It lets you turn the Traction Control
System on and off. You cannot turn
off the TCS while the TCS indicator
light is flashing.
Deactivate the system by pressing
the TCS On/Off switch. The TCS
indicator light comes on as a reminder. Pressing the switch again
turns the system back on. The Traction Control System turns
on every time you start the engine,
even if you turned it off the last time
you drove the vehicle.
TCS Indicator
The TCS indicator comes on or flashes under the following condi-
tions:
When you turn the ignition switch
to ON (II).

When you manually turn off the
TCS.
It flashes when the TCS is
regulating wheelspin.
If the system's diagnostics senses a problem in the TCS, the indica-
tor will come on and stay on.
If the brakes overheat, the
indicator will come on. If the TCS indicator comes on and
stays on for more than 10 minutes
while driving, pull to the side of the road when it is safe and turn off the
engine. Reset the system by
restarting the engine, and watch the
TCS indicator. If the indicator remains on, or comes back on whiledriving, have the system inspected
by your Honda dealer. You can still drive the vehicle without TCS.
This indicator will come on along with the ABS indicator if there is aproblem in the anti-lock brakesystem (see ABS Indicator on page 206
).
The TCS indicator may occasionally
come on for one or two seconds and
then go out. This is normal.

Towing a Trailer

Driving Safely With a Trailer
The added weight, length, and height of a trailer will affect your
vehicle's handling and performance, so driving with a trailer requires
some special driving skills and

techniques.

For your safety and the safety of
others, take time to practice driving
maneuvers before heading for the
open road, and follow the guidelines
discussed below.
Towing Speeds and Gears
Driving slower than normal in all driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D 4
position when towing
a trailer on level roads. D 3
is the
proper shift lever position to use when towing a trailer in hilly terrain.
(See "Driving on Hills" in the next

column for additional gear
information.)
Making Turns and Braking

Make turns more slowly and wider
than normal. The trailer tracks a smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and distance for braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknife or turn over.

Driving on Hills

When climbing hills, closely watch your temperature gauge. If it nearsthe red mark, turn the air
conditioning off, reduce speed and, if
necessary, pull to the side of the
road to let the engine cool. Do notdrive over 45 mph (72 km/h) on a
long uphill stretch.
If the transmission shifts frequently
between 3rd and 4th gears while
going up a hill, shift to D 3
. If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator,
as this can cause the transmission to

overheat.

When driving down hills, reduce your speed and shift down to 2ndgear. Do not "ride" the brakes, and
remember it will take longer to slowdown and stop when towing a trailer.

Spark Plugs

7. Torque the spark plug. (If you do not have a torque wrench, tighten
the spark plug two-thirds of a turn
after it contacts the cylinder head.)
Tightening torque:
13 lbf .
ft (18 N .
m, 1.8 kgf.m)
Tighten the spark plugs carefully. A
spark plug that is too loose can
overheat and damage the engine. Overtightening can cause damage to

the threads in the cylinder head.

8. Install the ignition coil. Reinstall
the hexagon socket head cap bolt.
9. Push the wire connector on to the ignition coil. Make sure it locks in

place.

10. Repeat this procedure for the other five spark plugs.
11. Reinstall the cover on the front cylinder bank while putting its
mounting clip in the hole on the
passenger's side. Secure the cover
by turning the heads of the two holding clips one-quarter turnclockwise with a flat-tippedscrewdriver.

Taking Care of the Unexpected

This section covers the more- common problems that motorists
experience with their vehicles. It
gives you information about how to safely evaluate the problem and what
to do to correct it. If the problem has stranded you on the side of the road,
you may be able to get going again. If not, you will also find instructions
on getting your vehicle towed. Compact Spare Tire....................... 286

If Your Engine Overheats

The pointer of your vehicle's
temperature gauge should stay in

the midrange under most conditions.
It may go higher if you are driving up
a long steep hill on a very hot day. If
it climbs to the red mark, you should

determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your vehicle can overheat for several

reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the heating and cooling/ climate control system and all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coining from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If the high heat is due to overloading (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving.

NOTICE

Steam and spray from an

overheated engine can
seriously scald you.

Do not open the hood if steam

is coming out.ProCarManuals.comMain Menu Table of Contents s t

If Your Engine Overheats

4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 311).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page187). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes off. 10.Start the engine and set the
temperature control dial tomaximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and refilled with the proper mixture assoon as you can.
11.Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engineneeds repair. (See Emergency
Towing on page 311.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.ProCarManuals.comMain Menu Table of Contents s t
