Low Oil Pressure Message
Your vehicle may have a low oil pressure warning
message.
Your oil pressure message lets you know when
you may have a problem with your engine oil
pressure.
When the engine is running and this message
appears, the engine oil level may be too low.
There may also be another problem causing low
oil pressure.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

INST ECONOMY (Instant Economy):Instant fuel
economy reects the fuel economy that the
vehicle has right now. Instant fuel economy varies
with your driving conditions, such as acceleration,
braking and the grade of the road being
traveled. Unlike average fuel economy, instant fuel
economy cannot be reset.
FUEL RANGE:The fuel range is an estimated
distance that your vehicle can travel on the
remaining fuel. The fuel economy used to calculate
the range is based on your driving history since
the last reset of the average speed.
FUEL USED:The fuel used display will show you
how much fuel has been used since the last
time it was reset. To reset the fuel used to zero,
press and hold the SET button while the fuel used
is displayed on the DIC and until the display
goes to zero.AVG SPEED (Average Speed):The average
speed display will show your average speed from
when you rst started your vehicle. To reset
the average speed, press and hold the SET button
while the average speed is displayed on the
DIC and until the speed resets to your current
speed.
OIL LIFE LEFT HOLD SET TO RESET:This
message displays the current percentage of the oil
life by the engine oil life system. Be careful not
to reset this display other than when the oil
has been changed. See “How to Reset the Engine
Oil Life System” underEngine Oil Life System
on page 368for more information.
In addition to the engine oil life system monitoring
the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on
page 475andEngine Oil on page 365.

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.
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 transaxle uid, engine oil, belts, 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 these sections before you
start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Trailer Wiring Harness
Your vehicle may have a trailer wiring harness
located at the rear of your vehicle. To use
the trailer wiring harness, you need a converter
kit. Contact your dealer for more information.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 364
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 (85 000 km) interval. See
Scheduled Maintenance on page 475for 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. Do not use
compressed air to clean the lter.

How to Add Automatic Transaxle Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle uid to use. See
Recommended Fluids and Lubricants on page 485.
If the uid level is low, add only enough of the
proper uid to bring the level into the
cross-hatched area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally less
than one pint (0.5 L). Do not overll.Notice:Use of the incorrect automatic
transaxle uid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
uid listed inRecommended Fluids and
Lubricants on page 485.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transaxle Fluid,” earlier in this section.
4. When the correct uid level is obtained, push
the dipstick back in all the way.

Windshield Replacement
Keep in mind that your windshield is part of the
Head-Up Display (HUD) system. If you ever have
to get your windshield replaced, be sure to get
one that is designed for HUD or your HUD image
may look blurred or out of focus.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
on page 475for more information.
Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts on page 486.

To reset the system, do the following:
1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads
LOW TIRE PRESSURE HOLD SET TO
RESET.
3. Press and hold the SET button until you hear
a chime, and TIRE PRESSURE RESET is
displayed.
You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC
will return to TIRE PRESSURE NORMAL. If the
LOW TIRE PRESSURE message comes back on,
the check tire pressure system has not reset.
Repeat the procedure.
The system completes the calibration process
during driving. The system learns the pressure at
each tire throughout the operating speed range
of your vehicle. The system normally takes
between 30 and 60 minutes of driving to learn
the tire pressures. The system normally takes
10 to 20 minutes of driving in each speed range
to learn tire pressures. The speed ranges are
20 to 40 mph (32 to 64 km/h), 40 to 60 mph
(64 to 96 km/h), and above 60 mph (96 km/h).
This time may be longer depending on yourindividual driving habits. The learning process
does not need to be completed during a single trip.
Once learned, the system will remember the tire
pressure until the system is reset.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. SeeWhen
It Is Time for New Tires on page 418andWheel
Replacement on page 422for more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire, If it
moves, use the folding wrench to tighten the cable.
SeeStoring a Flat or Spare Tire and Tools on
page 444.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 475.
