The DRL system makes the low-beam headlamps come
on at a reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The exterior lamps control is in the parking lamps
only position (This applies only to vehicles that
are rst sold in Canada).
The light sensor detects daytime light.
The parking brake is released or the vehicle is not
in PARK.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights
are not on unless you turn the exterior lamps control to
the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when they are needed.
Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, and the instrument panel
lights. The radio lights will also be dim.Your vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Make sure it is not covered or the automatic headlamp
system will be on when it is not needed.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the automatic
headlamp systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and automatic headlamp systems will only
be affected when the light sensor sees a change
in lighting lasting longer than this delay.
If you start your vehicle in a dark garage, the automatic
headlamp system comes on immediately. Once you
leave the garage, it takes about one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure
the instrument panel brightness control is in the full
bright position. See “Instrument Panel Brightness
Control” underInstrument Panel Brightness on
page 3-16.
To idle your vehicle with the automatic headlamp
system off, turn the ignition on and set the exterior light
switch to the off/on position. For Canadian vehicles,
the transmission must stay in PARK (P) for this function.
As with any vehicle, you should turn on the regular
headlamps when they are needed.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
When in manual shift mode, the odometer will change
from the vehicle’s mileage to the letter M, for manual
mode, and a number indicating the requested gear
range when moving the shift lever forward or rearward.
For more information seeAutomatic Transmission
Operation on page 2-27.
Your vehicle has a tamper resistant odometer.
Repair or replacement of your instrument panel cluster
should only be performed by your dealer/retailer.
Trip Odometer
The trip odometer can display how far you have driven
since you last reset it.
For more information seeDIC Operation and Displays
on page 3-43.
Tachometer
The tachometer
shows your engine
speed in revolutions
per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.2.4L and 3.6L Engine

if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might hear
the antilock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same time. In
many emergencies, steering can help you more than
even the very best braking.
Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transmission to limit wheel spin.
Also, the traction control system activates the
appropriate corner brakes to gain even quicker control
to limit wheel spin.This light, located on the
instrument panel, will come
on when your Traction
Control System is limiting
wheel spin.
You may feel or hear the system working, but this is
normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-10.
The Traction Control System operates in all transmission
shift lever positions except park or neutral. But the
system can upshift the transmission only as high as the
shift lever position you’ve chosen, so you should use
the lower gears only when necessary. SeeAutomatic
Transmission Operation on page 2-27.

Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” (towing your
vehicle with all four wheels on the ground) and “dolly
towing” (towing your vehicle with two wheels on
the ground and two wheels up on a device known
as a “dolly”).
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.
Here are some important things to consider before you
do recreational vehicle towing:
What’s the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer’s
recommendations.
How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
Do you have the proper towing equipment? See
your dealer/retailer or trailering professional for
additional advice and equipment recommendations.
Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you’ll
want to make sure your vehicle is prepared to be
towed. SeeBefore Leaving on a Long Trip on
page 4-13.
Dinghy Towing
If you have the 3.9L V6 engine with the four-speed
automatic transmission, your vehicle cannot be dinghy
towed.
If your vehicle does not have the 3.9L V6 engine with a
four-speed automatic transmission, it can be dinghy
towed.
When dinghy towing your vehicle, the vehicle should be
run at the beginning of each day and at each RV fuel
stop for about ve minutes. This will ensure proper
lubrication of transmission components.
4-26

Driving On Grades
When towing a trailer on long uphill grades and the
outside temperature is above 85°F (29°C), reduce your
vehicle speed to 45 mph (72 km/h) to avoid overheating
the engine cooling system.
Reduce speed and shift to a lower gearbeforeyou start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.But if you ever have to park your rig on a hill, here is
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P) for an automatic transmission or into
gear for a manual transmission. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P).
5. Release the regular brakes.
4-33

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transmission uid (do not
overll), engine oil, drive belt, cooling system and
brake system. Each of these is covered in this manual,
and the Index will help you nd them quickly. If you
are trailering, it is a good idea to review this information
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-33.
