9-12 Driving and Operating
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑44.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

9-60 Driving and Operating
Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load. 4. Reapply the brake pedal. Then
apply the parking brake and shift
into P (Park).
5. Release the brake pedal.Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer is clear of the chocks.
7. Stop and have someone pick up and store the chocks.
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 10‑20.
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

It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN,with the engine off.
2. Press the DIC MENU button to display the Vehicle
Information menu.
3. Press either the up or down arrows to view REMAINING
OIL LIFE.
4. Press the SET/CLR button until 100% is displayed.
5. Turn the key to LOCK/OFF.
Or:
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds. The system is reset when the
CHANGE ENGINE OIL SOON
message goes off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

How to Check Automatic

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 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. Contact your
dealer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
on page 13‑17.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11‑3, and be sure
to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.Engine Air Cleaner/Filter
See Engine Compartment Overview
on page 10‑6 for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect or replace the air cleaner/
filter at the scheduled maintenance
intervals. See Maintenance
Schedule on page 11‑3 for more
information. If driving in dusty/dirty
conditions, inspect the filter at each
engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains covered with dirt, a new
filter is required. Never use
compressed air to clean the filter. To inspect or replace the engine air
cleaner/filter:
1. Open the hood. See
Hood on
page 10‑5.
2. Locate the air filter housing on the passenger side of the engine
compartment. See Engine
Compartment Overview on
page 10‑6.
3. Remove the four air cleaner housing cover screws.

6. 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 10‑42.
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 10‑42.
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.
