Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual's Maintenance Schedule or
Index for more information. Things
that are especially important in
trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
on page 9‑20.
Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's
tires

Vehicle Care 9-13
What to Do with Used Oil
Used engine oil contains elements
that can be unhealthy for your skin
and could even cause cancer. Do
not let used oil stay on your skin.
Clean your skin and nails with soap
and water, or a good hand cleaner.
Wash or properly dispose of clothing
or rags. See the manufacturer's
warnings about the use and
disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies of
water. Recycle it by taking it to a
place that collects used oil.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer/retailer service department
and have it repaired as soon as
possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at your dealer/retailer service
department. Contact your dealer/
retailer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
on
page 12‑12. Change the fluid and filter at the
intervals listed in
Scheduled
Maintenance
on page 10‑2, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 10‑7.
Engine Air Cleaner/Filter
See Engine Compartment Overviewon page 9‑6
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
Maintenance IIintervals and replace
it at the first oil change after each
83 000 km (50,000 mile) interval.
See Scheduled Maintenance
on
page 10‑2

Vehicle Care 9-83
4. Turn all accessories off.
5. To prevent the battery fromdraining while the vehicle is
being towed, remove fuse 32,
the Discrete Logic Ignition
Switch fuse, from the instrument
panel fuse block and store it in a
safe location. See Instrument
Panel Fuse Block on page 9‑42.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination has been
reached:
1. Set the parking brake.
2. Shift the transmission to
P (Park).
3. Turn the ignition key to LOCK/OFF.
4. Install fuse 32, the Discrete Logic Ignition Switch fuse. See
Instrument Panel Fuse Block
on
page 9‑42.
5. Start the engine and let it idle for more than three minutes before
driving the vehicle.
Notice: Too much or too
little fluid can damage the
transmission. Be sure that the
transmission fluid is at the proper
level before towing with all four
wheels on the ground. Notice:
Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.
Dolly Towing
(All-Wheel‐Drive Vehicles)
All-wheel‐drive vehicles should not
be towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.

10-4 Service and Maintenance

environment. Applying silicone
grease on weatherstrips with a
clean cloth makes them last
longer, seal better, and not stick
or squeak.
