VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
•Store the removed IOD fuse in the Power Distribution
Center location #11 labeled “IOD Storage.”
•Or, disconnect the negative cable from the battery.
•Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the

Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H”,
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, and you hear continuous chimes, turn the
engine off immediately, and call for service.

Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking, tears,
cuts, abrasion, and excessive swelling suggest deteriora-
tion of the rubber. Particular attention should be made to
examining those hose surfaces nearest to high heat
sources, such as the exhaust manifold.Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Often fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done when-
ever the brake system is serviced and every engine oil
change.
MAINTAINING YOUR VEHICLE 331

Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the “Brake Warning Light” shows system failure.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However, low
fluid level may be caused by a leak and a checkup may be
needed.

Under frequent heavy-duty driving conditions,
change all lubricants and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service to prevent excessive
wear.

WARNING!
Airbag Warning Light
You will want to have the airbag system ready to inflate for
your protection in an impact. The airbag system is designed
to be maintenance free. If any of the following occurs, have
an authorized dealer service the system promptly:
•Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Even if the display still reads a few degrees above
32°F (0°C), the road surface may be icy, particularly
in woods or on bridges. Drive carefully under such
conditions to prevent an accident and possible per-
sonal injury or property damage.
Step Button
Press the STEP button to cycle through all of the displays.
The displays are: Average Miles/GAL, Miles To Empty,
Trip Miles, Time Elapsed, Miles To Service, Tire PSI, and
Blank Screen.
Average Miles/GAL
Shows the average fuel economy in miles per gallon
(MPG), or liters per 100 km (L/100 km) since the last
reset.Miles To Empty
Shows the estimated distance that can be traveled before
the fuel gauge shows E (Empty). The distance is calcu-
lated by multiplying the amount of fuel remaining by the
projected fuel economy. The distance predicted will
change every few seconds to a higher or lower number as
these factors change. This display cannot be reset.
Trip Miles
Shows the distance traveled since the last reset.
Time Elapsed
Shows the accumulated ignition ON time since the last
reset.
Miles To Service
Shows the amount of miles remaining until service is
required (owner selected).
136 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent mechanic.
