2003 GMC YUKON DENALI flat tire

A chiid in a rear-facing chiid restraint can be
seriously injured or killed if the right front
passenger’s air bag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating air bag. Be sure the air
bag is
off before using a rear-facing child
restraint in
the right front seat position.
Even though the passenger sensing system
is
designed to turn off the passenger’s frontal air
bag
if the system detects a rear-facing child
restraint, no system is fail-safe, and no one can
guarantee that an air bag will not deploy under
some unusual circumstance, even though
it is
turned off. General Motors therefore
recommends that rear-facing child restraints be
secured in the rear seat whenever possible,
even
if the air bag is off.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as
it will go. It is
better to secure the child restraint in a rear seat. If
your vehicle has the passenger sensing system and
you need to secure a rear-facing child restraint in
the right front passenger’s seat, the passengers frontal
air bag must be
off. See Passenger Sensing System
on page 1-81 and Securing a Chiid Restraint in tire Right
Front Seat Position on page
1-68 for more on this
including important safety information.
Wherever you install it, be sure
to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle.
Be sure to properly secure
any child restraint in your vehicle
- even when no
child is in it.
Top Strap
Some child restraints have a top strap, or “top tether”.
It can help restrain the child restraint during a collision.
For it
to work, a top strap must be properly anchored
to the vehicle. Some top strap-equipped child restraints
are designed for use with or without the
top strap
being anchored. Others require the top strap always
to
be anchored. Be sure to read and follow the
instructions for your child restraint. If yours requires that
the top strap be anchored, don’t use the restraint
unless it is anchored properly.

Operating Your All-Wheel-Drive
Vehicle
Off Paved Roads
Many of the same design features that help make your
vehicle responsive on paved roads during poor weather
conditions
- features like all-wheel drive - help make it
much better suited for off-road use than a conventional
passenger car.
Its higher ground clearance also helps
your vehicle step over some off-road obstacles. But your
vehicle doesn’t have features like special underbody
shielding and
a transfer case low gear range, things that
are usually thought necessary for extended or severe
off-road service. This guide is for operating your vehicle
off paved roads.
Also, see
Braking on page 4-6.
Off-road driving can be great fun. But it does have
some definite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you’ve left the great North American
road system behind. Traffic lanes aren’t marked.
Curves aren’t banked. There are no road signs.
Surfaces can be slippery, rough, uphill or downhill.
In short, you’ve gone right back
to nature.
Off-road driving involves some new skills. And that’s
why it’s very important that you read this guide.
You’ll find many driving tips and suggestions.
These will help make your off-road driving safer
and more enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure
to have all necessary maintenance
and service work done. Check
to make sure all
underbody shields (if
so equipped) are properly
attached.
Is there enough fuel? Is the spare tire fully
inflated? Are the fluid levels up where they should be?
What are the local laws that apply
to off-roading
where you’ll be driving? If you don’t know, you should
check with law enforcement people in the area. Will you
be on someone’s private land? If
so, be sure to get
the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how
to load your vehicle.
The heaviest things should be on the load floor and
forward
of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain doesn’t
toss things around.
4-1 6

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect
to
move slightly slower at night.
When you want to leave the freeway, move
to the
proper lane well in advance.
If you miss your exit, do
not, under any circumstances,
stop and back up. Drive
on
to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according
to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll be
ready and willing
to help if you need it. dere
are some things you can check before a trip:

Windshield Washer Fluid: Is the reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked

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 “highway
hypnosis”? 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

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. See Operating
Your All- Wheel-Drive Vehicle
Off Paved Roads on
page
4- 16 for information about driving off-road.

Towing Loading Your Vehicle
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page
7-5.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
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 “dinghy towing” (towing your vehicle
with all four wheels on the ground) and “dolly towing”
(towing your vehicle with two wheels
on the ground and
two wheels
up on a device known as a “dolly”).
Your vehicle was not designed
to be towed with any of
its wheels on the ground.
If your vehicle must be
towed, see Towing Your Vehicle on page
4-44.
Notices Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two
of
its wheels on the ground, will damage drivetrain
components. Don’t tow an all-wheel-drive vehicle
if
any of its wheels will be on the ground.

capacity of your vehicle. This is called the GVWR (Gross
Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
The Certificationmire 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

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 vehicie ‘Weight (GVLiij
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 will 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

maximum load capacity.

If you’re using a weight-carrying or a weight-distributing
hitch, the trailer tongue weight (A) should be
10 percent

15 percent of the total loaded trailer weight (B).
Do not exceed the maximum allowable tongue weight
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. for
your
vehicle.
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 label at the rear edge of the driver’s door
or
see Loading Your Vehicle on page 4-44. Then be
sure you don’t go over the GVW and rear axle limits for
your vehicle, including the weight of the trailer tongue.
If you use a weight distributing hitch, make sure
you don’t go over the rear axle limit before you apply
the weight distributing spring bars.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your Warranty booklet for details.

are dangerous.
Overloading your tires can cause
overheating as
a result of too much
friction. You could have an air-out and a
serious accident. See “Loading Your
Vehicle”
in the Index.
0 Underinflated tires pose the same danger
as overloaded tires. The resulting accident could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
Inflation -- Tire Pressure
The CertificationKire label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours
or driven
no more than
1 mile (1.6 km).
