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 eliminate the leading highway safety
problem is for people never to drink alcohol and then
drive. But what if people do? How much is“too much”if
someone 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.
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 liquors 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

Never go downhill with the transmission in
NEUTRAL (N), or with the clutch pedal pressed
down in a manual shift. This is called“free-wheeling”.
Your brakes will have to do all the work and could
overheat and fade.
Q:Am I likely to stall when going downhill?
A:It’s much more likely to happen going uphill. But if
it happens going downhill, here’s what to do.
Stop your vehicle by applying the regular brakes.
Apply the parking brake.
Shift to PARK (P) (or to neutral with the manual
transmission) and, while still braking, restart the
engine.
Shift back to a low gear, release the parking brake,
and drive straight down.
If the engine won’t start, get out and get help.
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.

Payload
This is the maximum load capacity that your vehicle can
carry. Be sure to include the weight of the occupants
as part of your load. If you added any accessories
or equipment after your vehicle left the factory,
remember to subtract the weight of these things from
the payload. Your dealer can help you with this.
Remember not to exceed the Gross Axle Weight Rating
(GAWR) of the front or rear axle. SeeLoading Your
Vehicle on page 4-46.
Two-Tiered Loading
By positioning four 2”x6”wooden planks across the
width of the pickup box, you can create an upper
load platform. The planks must be inserted in the pickup
box depressions. The length of the planks must allow
for at least a 3/4 inch (2 cm) bearing surface on
each end of the plank.
When using this upper load platform, be sure the load is
securely tied down to prevent it from shifting. The
load’s center of gravity should be positioned in a zone
over the rear axle.
Any load that extends beyond the vehicle’s taillamp
area must be properly marked according to local laws
and regulations.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the rear axle. SeeLoading Your
Vehicle on page 4-46.
Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.
Notice:Your warranty does not cover parts or
components that fail because of overloading.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the rear axle. SeeLoading Your
Vehicle on page 4-46.
Truck-Camper Loading Information
The Truck-Camper Loading label is located on the
passenger’s door near the latch. It will tell you if your
vehicle can carry a slide-in camper, how much of a load
your vehicle can carry, and how to correctly spread
out your load. Also, it will help you match the right
slide-in camper to your vehicle.
When the truck is used to carry a slide-in camper, the
total cargo load of the truck consists of the
manufacturer’s camper weightgure, the weight of
installed additional camper equipment not included in
the manufacturer’s camper weightgure, the weight of
camper cargo, and the weight of passengers in the
camper. The total cargo load should not exceed
the truck’s cargo weight rating and the camper’s center
of gravity should fall within the truck’s recommended
center of gravity zone when installed.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear and cracking. See“Wiper
Blade Check”underAt Least Twice a Year on
page 6-26.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
seeNormal Maintenance Replacement Parts on
page 5-96.
Notice:Use care when removing or installing a
blade assembly. Accidental bumping can cause the
arm to fall back and strike the windshield.
1. To remove the old wiper blades, lift the wiper arm
until it locks into a vertical position.
