Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring.
The arrows on your instrument panel will ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ash, telling other drivers
you are about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the
trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not.
It is important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you 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.
If you are towing a trailer that weighs more than 1,000 lbs
(450 kg), drive in AUTOMATIC OVERDRIVE (D) or,
as you need to, a lower gear. This will minimize heat
build-up and extend the life of your transaxle.
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, do the
following:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel 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 then shift to PARK (P).
5. Release the regular brakes.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-10
for the location of the engine air cleaner/lter.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after
each 50,000 mile (83 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information.
If you are driving in dusty/dirty conditions, inspect the
lter at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/lter, remove the lter
from the vehicle and lightly shake the lter to release
loose dust and dirt. If the lter remains caked with
dirt, a new lter is required.To inspect or replace the air cleaner/lter, do the
following:
1. Remove the two clamps on the duct.
2. Remove the duct.
3. Unlatch the two hooks on top of the engine air
cleaner/lter housing.
4. Inspect or replace the engine air cleaner/lter.
5. Align the tabs located on the bottom of the panel
with the slots at the bottom of the housing. 3.5L V6 Engine shown, 3.6L V6 Engine similar

6. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs are seated
correctly in the slots.
7. Put the duct back on and reinstall the clamps.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air; it helps
to stop ames if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.
Automatic Transaxle Fluid
When to Check and Change
Automatic Transaxle Fluid
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be
sure to use the transaxle uid listed inRecommended
Fluids and Lubricants on page 6-12.
How to Check Automatic
Transaxle Fluid
Because this operation can be a little difficult, you may
choose to have this done at the dealership service
department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
Notice:Too much or too little uid can damage the
transaxle. Too much can mean that some of the uid
could come out and fall on hot engine or exhaust
system parts, starting a re. Too little uid could
cause the transaxle to overheat. Be sure to get an
accurate reading if you check the transaxle uid.

4. Open the hood on the other vehicle and locate the
positive (+) and negative (−) terminal locations on
that vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose. The terminal is
located under a tethered cap at the front of the
underhood fuse block. SeeEngine Compartment
Overview on page 5-10for more information
on location.
If your vehicle has the
3.5L V6 engine, squeeze
the tabs and swing the cap
out of the way to access
the remote positive (+)
terminal.If your vehicle has the
3.6L V6 engine, pull up
on the cap to access
the remote positive (+)
terminal.
You should always use the remote positive (+)
terminal instead of the positive (+) terminal on
the battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan. 3.5L V6 Engine
