Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior, trunk or underhood lamps
on. If you leave any of
these lamps on while the ignition is in LOCK or OFF,
they will automatically turn off after 10 minutes. The
lamps won’t come back
on again until you do one of
the following:
Turn the ignition to RUN or ACCESSORY.
Turn the interior lamps thumbwheel completely to
the right, then back slightly to the left.
Open (or close and reopen) a door that is closed.
If the vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn
off the lamps
after only three minutes.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency supplies in
your trunk. Include
an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight,
a red
cloth and a couple of reflective warning triangles. And,
if you will be driving under severe conditions, include
a small bag
of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.

Loading Your Vehicle
.
1 TIRE-LOADING INFORMATION
1 OCCUPANTS VEHiCLE 6
OT, ADD 28KPA(4PSI)
FOR MORE INFORMATION
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label is
on the inside of the trunk lid. The label tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also give you
important information about the number of people
that can be in your vehicle and the total weight you can
carry. This weight is called the vehicle capacity
weight and includes the weigh of all occupants, cargo
and all non-factory installed options. The
other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
4-35

If you do have a heavy load, spread it out. Don’t carry
more than
167 pounds (75 kg) in your trunk.
~ 3 not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and
it can change the way your vehicle
handles. These could cause you to lose
control and crash.
Also, overloading can
shorten the life of your vehicle.
Notice: Your warranty does not cover parts or
components that fail because
of overloading.
If you put things inside your vehicle - like suitcases,
tools, packages or anything else - they will go as
fast as the vehicle goes. If you have to stop or
turn quickly,
or if there is a crash, they’ll keep going. Things you
put insi your
ve--.:le can s.. .. and injure people in a sudden stop or turn,
or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as you
can. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them
are above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure
it whenever you can.
Don’t leave a seat folded down unless you
need to.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GWV)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. And
if you tow a trailer, you must add the
tongue load to the GVW because your vehicle will
be carrying that weight, too. See Loading Your Vehicle
on page 4-35 for more information about your
vehicle’s maximum load capacity.
A
If you’re using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue
(A) should
weigh
10-15 percent of the total loaded trailer
weight
(B).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see if the weights
are proper.
If they aren’t, you may be able to get them
right simply by moving some items around in the
trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limit
for cold tires. You’ll find these numbers on the Tire
Loading Information label, found on the inside of
the trunk lid,
or see Loading Your Vehicle on page 4-35.
Then be sure you don’t go over the GVW limit for
your vehicle, including the weight of the trailer
tongue.

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system can
determine
if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into
the
atmosphere. See Malfunction Indicator Lamp on
page
3-32.
Notice: If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not fit properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See “Malfunction Indicator Lamp” in
the Index.
Filling a Portable Fuel Container
~ .-ver fil. - portable fL-- cc..-ainer while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor. You can be badly burned and your vehicle
damaged if this occurs.
To help avoid injury to
you and others:
Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle,
in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Don’t smoke while pumping gasoline.
