CAUTION:
Children who are up against, or very close to,
any air bag when it inflates can be seriously
injured or killed. Air bags plus lap
-shoulder belts
offer outstanding protection for adults and older
children, but not for young children and infants.
Neither the vehicle's safety belt system nor its
air bag system is designed for them. Young
children and infants need the protection that a
child restraint system can provide.
Q:What are the different types of add-on
child restraints?
A:Add-on child restraints, which are purchased
by the vehicle's owner, are available in four basic
types. Selection of a particular restraint should
take into consideration not only the child's weight,
height and age but also whether or not the restraint
will be compatible with the motor vehicle in which
it will be used.
For most basic types of child restraints, there are
many different models available. When purchasing
a child restraint, be sure it is designed to be used
in a motor vehicle. If it is, the restraint will have a
label saying that it meets federal motor vehicle
safety standards.
The restraint manufacturer's instructions that
come with the restraint state the weight and
height limitations for a particular child restraint.
In addition, there are many kinds of restraints
available for children with special needs.

2-27 Leaving Your Vehicle With the
Engine Running
CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pressing
the button on the console shift lever. If you can, it means
that the shift lever wasn't fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don't shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called ªtorque lock.º
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver's seat. To find out how, see ªShifting Into
PARK (P)º in the Index.
When you are ready to drive, move the shift lever out
of PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).

2-52 Luggage Carrier
CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier
-- like paneling, plywood, a mattress,
and so forth
-- the wind can catch it as you
drive along. This can cause you to lose control.
What you are carrying could be violently torn
off, and this could cause you or other drivers
to have a collision, and of course damage your
vehicle. You may be able to carry something like
this inside. But, never carry something longer
or wider than the luggage carrier on top of
your vehicle.
A luggage carrier allows you to load things on top of
your vehicle. The luggage carrier has slats and side rails
attached to the roof, sliding crossrails and places to use
for tying things down. These let you load some other
things on top of your vehicle, as long as they are not
wider or longer than the luggage carrier.To slide the crossrails to where you want them, pull up on
the lever on each side of the crossrail. This will release
the crossrail and allow you to slide it. When the crossrail
is where you want it, push down on the lever to lock it
into place.
NOTICE:
Loading cargo that weighs more than 220 lbs. (100 kg)
on the luggage carrier may damage your vehicle.
When you carry cargo on the luggage carrier
of a proper size and weight, put it on the slats,
and distribute the weight evenly. Then slide the
crossrail up against the rear of the load, to help
keep it from moving. You can then tie it down.
Cargo containers must be loaded on the
crossrails only.
Don't exceed the maximum vehicle capacity when loading
your vehicle. For more information on vehicle capacity and
loading, see ªLoading Your Vehicleº in the Index.
To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage carrier is
locked and cargo is still securely fastened.

Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It's the number one contributor to
the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to
drive a vehicle:

Judgment

Muscular Coordination

Vision

Attentiveness.
Police records show that almost half of all motor
vehicle
-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was drinking
and driving. In recent years, about 16,000 annual motor
vehicle
-related deaths have been associated with the use
of alcohol, with more than 300,000 people injured.Many adults
-- by some estimates, nearly half the
adult population
-- choose never to drink alcohol,
so they never drive after drinking. For persons under 21,
it's against the law in every U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws.
The obvious way to solve the leading highway safety
problem is for people never to drink alcohol and then
drive. But what if people do? How much is ªtoo muchº
if the driver plans to drive? It's a lot less than many
might think. Although it depends on each person
and situation, here is some general information on
the problem.
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:

The amount of alcohol consumed

The drinker's body weight

The amount of food that is consumed before
and during drinking

The length of time it has taken the drinker to
consume the alcohol.

4-4
According to the American Medical Association, a
180
-lb. (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about 0.06 percent. The person would reach the
same BAC by drinking three 4
-ounce (120 ml) glasses
of wine or three mixed drinks if each had 1
-1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.
It's the amount of alcohol that counts. For example,
if the same person drank three double martinis
(3 ounces or 90 ml of liquor each) within an hour,
the person's BAC would be close to 0.12 percent.
A person who consumes food just before or during
drinking will have a somewhat lower BAC level.
There is a gender difference, too. Women generally
have a lower relative percentage of body water than
men. Since alcohol is carried in body water, this means
that a woman generally will reach a higher BAC level
than a man of her same body weight when each has the
same number of drinks.
The law in an increasing number of U.S. states, and
throughout Canada, sets the legal limit at 0.08 percent.
In some other countries, the limit is even lower.
For example, it is 0.05 percent in both France and
Germany. The BAC limit for all commercial drivers
in the United States is 0.04 percent.
The BAC will be over 0.10 percent after three to
six drinks (in one hour). Of course, as we've seen,
it depends on how much alcohol is in the drinks,
and how quickly the person drinks them.

4-6
Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you're driving on snow or ice,
it's easy to ask more of those control systems than
the tires and road can provide. That means you can
lose control of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That's perception time. Then you have to bring up
your foot and do it. That's reaction time.
Average reaction time is about 3/4 of a second.
But that's only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part. So do alcohol, drugs and
frustration. But even in 3/4 of a second, a vehicle
moving at 60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it's pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.

4-26 Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline of a hill. If this happens, you have to decide
whether to try to drive across the incline. Here are some
things to consider:

A hill that can be driven straight up or down
may be too steep to drive across. When you go
straight up or down a hill, the length of the wheel
base (the distance from the front wheels to the
rear wheels) reduces the likelihood the vehicle will
tumble end over end. But when you drive across
an incline, the much more narrow track width
(the distance between the left and right wheels) may
not prevent the vehicle from tilting and rolling over.
Also, driving across an incline puts more weight on
the downhill wheels. This could cause a downhill
slide or a rollover.
Surface conditions can be a problem when you drive
across a hill. Loose gravel, muddy spots, or even wet
grass can cause your tires to slip sideways, downhill.
If the vehicle slips sideways, it can hit something
that will trip it (a rock, a rut, etc.) and roll over.

Hidden obstacles can make the steepness of the
incline even worse. If you drive across a rock with
the uphill wheels, or if the downhill wheels drop into
a rut or depression, your vehicle can tilt even more.
For reasons like these, you need to decide carefully
whether to try to drive across an incline. Just because the
trail goes across the incline doesn't mean you have to
drive it. The last vehicle to try it might have rolled over.
CAUTION:
Driving across an incline that's too steep will
make your vehicle roll over. You could be
seriously injured or killed. If you have any
doubt about the steepness of the incline, don't
drive across it. Find another route instead.

4-44
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle
-- such as behind
a motorhome. The two most common types of
recreational vehicle towing are known as ªdinghy
towingº (towing your vehicle with all four wheels on
the ground) and ªdolly towingº (towing your vehicle
with two wheels on the ground and two wheels up on
a device know as a ªdollyº).
Your vehicle was not designed to be towed with any
of it's wheels on the ground. If your vehicle must be
towed, see ªTowing Your Vehicleº in the Index.
Loading Your Vehicle
The Certification/Tire label is found on the driver's door
edge, above the door latch. 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, cargo and trailer tongue weight,
if pulling a trailer.

4-45
The Certification/Tire label also tells you the maximum
weights for the front and rear axles, called 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.
If you do have a heavy load, you should spread
it out.
Similar appearing vehicles may have different
GVWRs and payloads. Please note your vehicle's
Certification/Tire label or consult your dealer for
additional details.
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.
Using heavier suspension components to get added
durability might not change your vehicle's weight
ratings. Ask your dealer to help you load you vehicle
the right way.
NOTICE:
Your warranty does not cover parts or components
that fail because of overloading.

4-46
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's a crash, they'll keep going.
CAUTION:
Things you put inside your vehicle can strike and
injure people in a sudden stop or turn, or in a crash.

Put things in the cargo area of your vehicle.
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.
There's also important loading information for off-road
driving in this manual. See ªLoading Your Vehicle for
Off
-Road Drivingº in the Index.
Electronically Controlled Air
Suspension System
Your vehicle is equipped with an electronically
controlled air suspension system that automatically
keeps your vehicle level as you load and unload.
The system includes a compressor, two height
sensors and two air springs supporting the rear axle.
The system also has an internal clock to prevent
overheating. If the system overheats, all leveling
function stops until the system cools down.
During this time, the indicator light on the air
inflator system will be flashing.
The ignition has to be on for the system to inflate,
in order to raise the vehicle to the standard ride height
after loading. The system can lower the vehicle to the
standard ride height after unloading with the ignition on
and also for up to 30 minutes after the ignition has been
turned off.
You may hear the compressor operating when you load
your vehicle, and periodically as the system adjusts the
vehicle to the standard ride height.
Load leveling will not function normally with the inflator
hose attached to the inflator outlet. Remove the inflator
hose from the outlet during loading and unloading.
