Accessory Inflator System (Option)
Your vehicle may have an air inflator. With it, you
can inflate things like air mattresses and basketballs,
and you can also use it to bring your tires up to the
proper pressure.
The air inflator is located in the rear compartment on the
driver's side. To remove the cover, pull the tab on the
cover and pull it off.
The air inflator kit is stored in the glove box. It includes
a 20
-foot (6 m) hose with an air pressure gage and
nozzle adapters.
CAUTION:
Inflating something too much can make it
explode, and you or others could be injured. Be
sure to read the inflator instructions, and inflate
any object only to its recommended pressure.

Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?
Highway Hypnosis
Is there actually such a condition as ªhighway hypnosisº?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don't let it
happen to you! If it does, your vehicle can leave the
road in less than a second, and you could crash and
be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.

Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.

If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can
make your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you
go down a steep or long hill.
CAUTION:
If you don't shift down, your brakes could get so
hot that they wouldn't work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.

Loading Your Vehicle
The Certification/Tire label is found on the rear edge of
the driver's door.
The label shows the size of your original tires and the
inflation pressures needed to obtain the gross weight
capacity of your vehicle. This is called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
The Certification/Tire label also tells you the maximum
weights for the front and rear axles, called the Gross
Axle Weight Rating (GAWR).To find out the actual loads on your front and rear axles,
you need to go to a weigh station and weigh your vehicle.
Your dealer can help you with this. Be sure to spread out
your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle or the GAWR
for either the front or rear axle.
CAUTION:
Do 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.

4-37
If you're using a weight-carrying or a
weight
-distributing hitch, the trailer tongue weight (A)
should be 10 percent to 15 percent of the total loaded
trailer weight (B). Do not exceed the maximum
allowable tongue weight for your vehicle.
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
Certification/Tire Label at the rear edge of the driver's
door, or see ªTire Loadingº in the Index. Then be sure
you don't go over the GVW limit for your vehicle,
including the weight of the trailer tongue.
Hitches
It's important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why you'll need the right hitch. Here are
some rules to follow:

The bumpers on your vehicle are not intended
for hitches. Do not attach rental hitches or other
bumper
-type hitches to them. Use only a
frame
-mounted hitch that does not attach to
the bumper.

If you'll be pulling a trailer that, when loaded, will
weigh more than 2,000 lbs. (900kg). be sure to use a
properly mounted, weight
-carrying hitch and sway
control of the proper size. This equipment is very
important for proper vehicle loading and good
handling when you're driving.

Will you have to make any holes in the body of your
vehicle when you install a trailer hitch?
If you do, then be sure to seal the holes later when
you remove the hitch. If you don't seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle. See ªCarbon Monoxideº in the
Index. Dirt and water can, too.

If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake
to a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use in
a skid. In any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

5-21
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
The following steps will tell you how to use the jack and
change a tire.

5-24
3. To remove the compact spare tire from the cable, tilt
the retainer at the end of the cable so it can be pulled
up through the wheel opening.4. If your vehicle is an all
-wheel-drive vehicle, after
removing the compact spare tire, turn the wrench
clockwise to raise the cable back up.
On an AWD vehicle, you can not store a full
-size
tire under the vehicle. It should be stowed inside
the vehicle by the cable provided. See ªStoring the
Flat Tire on an All
-Wheel-Drive Vehicleº later in
this section.
If you have a front
-wheel-drive vehicle, the hoist
is used to store a full
-size or a flat road tire under the
vehicle. See ªStoring the Spare Tire and Toolsº and
ªStoring the Flat Tire on a Front
-Wheel-Drive
Vehicleº later in this section.
If the compact spare tire will not lower, check under the
vehicle to see if the tire is hanging loose and the cable
end and spring under the wheel plate are missing. If so,
the secondary latch system is engaged. See ªSecondary
Latch Systemº later in this section.
To continue changing the flat tire see ªRemoving
the Flat Tire and Installing the Spare Tireº later in
this section.

5-26 Secondary Latch System (If Equipped)
Your vehicle may have an underbody mounted tire hoist
assembly equipped with a secondary latch system. It's
designed to stop a tire from suddenly falling off your
vehicle if the cable holding the tire is damaged. For the
secondary latch to work, the tire must be stowed with
the valve stem pointing down.
Front
-wheel-drive vehicles use the underbody tire hoist
assembly to store either the compact spare or a flat road
tire. See ªStoring a Flat or Spare Tire and Toolsº in
the Index for instructions on storing the spare or flat
tire correctly.
If your vehicle is equipped with all
-wheel-drive, the
underbody tire hoist assembly stores only the compact
spare tire. See ªStoring the Spare Tire and Toolsº in
the Index for instructions. To store a flat full
-size tire
correctly, see ªStoring the Flat Tire on an
All
-Wheel-Drive Vehicleº in the Index.
CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly and
you and others could get hurt. Read and follow
the instructions listed below.
To release the spare tire from the secondary latch,
do the following:
CAUTION:
Someone standing too close during the procedure
could be injured by the jack. If the spare tire does
not slide off the jack completely, make sure no
one is behind you or on either side of you as you
pull the jack out from under the spare.
