CADILLAC ESCALADE EXT 2009 3.G Owners Manual

Magnetic Ride Control™
The vehicle may have the MagneRide control system.
MagneRide constantly checks speed, wheel position,
lift/dive and steering of the vehicle. The damping force
for each shock absorber and adjustment level is
chosen for the best ride and handling.
MagneRide also works with the tow/haul switch that,
when engaged, will provide more rmness from
the shock absorbers. This added control gives better
ride and handling when carrying heavy loads or towing a
trailer. SeeTow/Haul Mode on page 2-39for more
information.
Road Sensing Suspension
The Road Sensing Suspension (RSS) feature provides
superior vehicle ride and handling under a variety of
passenger and loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
RSS also interacts with the tow/haul mode that, when
engaged, will provide additional control of the shock
absorbers. This additional control results in better rideand handling characteristics when the vehicle is loaded
or towing a trailer. See “Tow/Haul Mode” under
Towing a Trailer on page 5-40.
Locking Rear Axle
Vehicles with a locking rear axle can give more traction
on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when traction is low,
this feature will allow the rear wheel with the most
traction to move the vehicle.
All-Wheel Drive (AWD) System
With this feature, engine power is sent to all four wheels
at all times. This is like four-wheel drive, but there is
no separate lever or switch to engage or disengage the
front axle. It is fully automatic, and adjusts itself as
needed for road conditions.
Steering
Power Steering
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
5-9

Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until out of the curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and nd
a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. These
problems can be avoided by braking — if you can stop
in time. But sometimes you cannot stop in time
because there is no room. That is the time for evasive
action — steering around the problem.
The vehicle can perform very well in emergencies like
these. First apply the brakes. SeeBraking on page 5-4.
It is better to remove as much speed as possiblefrom a collision. Then steer around the problem, to the
left or right depending on the space available.
An emergency like this requires close attention and a
quick decision. If holding the steering wheel at the
recommended 9 and 3 o’clock positions, it can be turned
a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
5-10

Off-Road Recovery
The vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that the vehicle straddles the edge of the
pavement. Turn the steering wheel 3 to 5 inches, 8 to
13 cm, (about one-eighth turn) until the right front
tire contacts the pavement edge. Then turn the steering
wheel to go straight down the roadway.
Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:
Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass. If
in doubt, wait.
Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your side
of the lane.
Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
Wait your turn to pass a slow vehicle.
When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver
has asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or area of
less danger.
5-11

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to the vehicle’s
three control systems. In the braking skid, the wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels
to spin.
Remember: Any traction control system helps avoid only
the acceleration skid. If the traction control system is
off, then an acceleration skid is best handled by easing
your foot off the accelerator pedal.
If the vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
the vehicle may straighten out. Always be ready for
a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, slow
down and adjust your driving to these conditions. It is
important to slow down on slippery surfaces because
stopping distance will be longer and vehicle control
more limited.While driving on a surface with reduced traction, try your
best to avoid sudden steering, acceleration, or braking,
including reducing vehicle speed by shifting to a lower
gear. Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until the
vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
Off-Road Driving
Vehicles with 22-inch tire/wheel assemblies should not
be driven off-road except on a level, solid surface.
Many of the vehicle design features that help make the
vehicle more responsive on paved roads during poor
weather conditions also help make it better suited
for off-road use than conventional passenger vehicles.
The vehicle does not have features usually thought to be
necessary for extended or severe off-road use such
as special underbody shielding and transfer case
low gear range.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Always wear your safety belt and observe safe driving
speeds, especially on rough terrain.
5-12

Drinking and driving can be very dangerous on any road
and this is certainly true for off-road driving. At the
very time you need special alertness and driving skills,
your reexes, perceptions, and judgment can be
affected by even a small amount of alcohol. You could
have a serious — or even fatal — accident if you
drink and drive or ride with a driver who has been
drinking.
Off-roading can be great fun but has some denite
hazards. The greatest of these is the terrain itself. When
off-road driving, traffic lanes are not marked, curves
are not banked, and there are no road signs. Surfaces
can be slippery, rough, uphill, or downhill.
Avoid sharp turns and abrupt maneuvers. Failure to
operate the vehicle correctly off-road could result in loss
of vehicle control or vehicle rollover.
Off-roading involves some new skills. That is why it is
very important that you read these driving tips and
suggestions to help make off-road driving safer
and more enjoyable.Before You Go Off-Roading
Have all necessary maintenance and service
work done.
Make sure there is enough fuel, that uid levels are
where they should be, and that the spare tire is fully
inated.
Be sure to read all the information about
all-wheel-drive vehicles in this manual.
Make sure all underbody shields, if the vehicle has
them, are properly attached.
Know the local laws that apply to off-roading where
you will be driving or check with law enforcement
people in the area.
Be sure to get the necessary permission if you will
be on private land.
5-13

If you think you will need some more ground clearance
at the front of your vehicle, you can remove the front
fascia lower air dam. The air dam is held in place by
two bolts and 10 snaps accessible from underneath the
front fascia.
To remove the air dam:
1. Remove the two outboard air dam bolts.
2. With a at-blade tool, disengage the snaps.
3. After the bolts are removed and the snaps are
disengaged, push forward on the air dam until it
is free.
Notice:Operating your vehicle for extended
periods without the front fascia lower air dam
installed can cause improper air ow to the engine.
Always be sure to replace the front fascia air
dam when you are nished off-road driving.
After off-roading, be sure to reinstall the air dam:
1. Line up the snaps and push the air dam rearward
to engage the snaps.
2. Install the two outboard bolts.Loading Your Vehicle for Off-Road
Driving
{CAUTION:
Cargo on the load oor piled higher than the
seatbacks can be thrown forward during a
sudden stop. You or your passengers could
be injured. Keep cargo below the top of the
seatbacks.
Unsecured cargo on the load oor can be
tossed about when driving over rough terrain.
You or your passengers can be struck by
ying objects. Secure the cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to roll
over. You can be seriously or fatally injured if
the vehicle rolls over. Put heavy loads inside
the cargo area, not on the roof. Keep cargo in
the cargo area as far forward and low as
possible.
5-14

There are some important things to remember about
how to load your vehicle.
The heaviest things should be on the oor, forward
of the rear axle. Put heavier items as far forward
as you can.
Be sure the load is properly secured, so things are
not tossed around.
You will nd other important information underLoading
the Vehicle on page 5-31andTires on page 6-54.
Environmental Concerns
Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. We recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
Always use established trails, roads, and areas that
have been specially set aside for public off-road
recreational driving and obey all posted regulations.
Avoid any driving practice that could damage
shrubs, owers, trees, or grasses or disturb wildlife.
This includes wheel-spinning, breaking down
trees, or unnecessary driving through streams or
over soft ground.
Always carry a litter bag and make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open res (where
permitted), camp stoves, and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch re from
the heat of the vehicle’s exhaust system.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to a remote area. Know the terrain and plan your
route. Get accurate maps of trails and terrain. Check to
see if there are any blocked or closed roads.
It is also a good idea to travel with at least one other
vehicle in case something happens to one of them.
For vehicles with a winch, be sure to read the winch
instructions. In a remote area, a winch can be handy if
you get stuck but you will want to know how to use
it properly.
Getting Familiar with Off-Road Driving
It is a good idea to practice in an area that is safe
and close to home before you go into the wilderness.
Off-roading requires some new and different skills.
Tune your senses to different kinds of signals. Your eyes
need to constantly sweep the terrain for unexpected
obstacles. Your ears need to listen for unusual tire
or engine sounds. Use your arms, hands, feet, and body
to respond to vibrations and vehicle bounce.
5-15

Controlling the vehicle is the key to successful off-road
driving. One of the best ways to control the vehicle
is to control the speed. At higher speeds:
You approach things faster and have less time to
react.
There is less time to scan the terrain for obstacles.
The vehicle has more bounce when driving over
obstacles.
More braking distance is needed, especially on an
unpaved surface.
{CAUTION:
When you are driving off-road, bouncing and quick
changes in direction can easily throw you out of
position. This could cause you to lose control and
crash. So, whether you are driving on or off the
road, you and your passengers should wear
safety belts.
Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain. Be familiar with the terrain and its many
different features.Surface Conditions:Off-roading surfaces can be
hard-packed dirt, gravel, rocks, grass, sand, mud, snow,
or ice. Each of these surfaces affects the vehicle’s
steering, acceleration, and braking in different ways.
Depending on the surface, slipping, sliding, wheel
spinning, delayed acceleration, poor traction, and longer
braking distances can occur.
Surface Obstacles:Unseen or hidden obstacles can
be hazardous. A rock, log, hole, rut, or bump can startle
you if you are not prepared for them. Often these
obstacles are hidden by grass, bushes, snow, or even
the rise and fall of the terrain itself.
Some things to consider:
Is the path ahead clear?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill?
Will you have to stop suddenly or change direction
quickly?
When driving over obstacles or rough terrain, keep a rm
grip on the steering wheel. Ruts, troughs, or other surface
features can jerk the wheel out of your hands.
When driving over bumps, rocks, or other obstacles, the
wheels can leave the ground. If this happens, even
with one or two wheels, you cannot control the vehicle
as well or at all.
5-16

Because you will be on an unpaved surface, it is
especially important to avoid sudden acceleration,
sudden turns, or sudden braking.
Off-roading requires a different kind of alertness from
driving on paved roads and highways. There are no road
signs, posted speed limits, or signal lights. Use good
judgment about what is safe and what is not.
Driving on Hills
Off-road driving often takes you up, down, or across a
hill. Driving safely on hills requires good judgment
and an understanding of what the vehicle can and
cannot do. There are some hills that simply cannot be
driven, no matter how well built the vehicle.
{CAUTION:
Many hills are simply too steep for any vehicle. If
you drive up them, you will stall. If you drive down
them, you cannot control your speed. If you drive
across them, you will roll over. You could be
seriously injured or killed. If you have any doubt
about the steepness, do not drive the hill.
Approaching a Hill
When you approach a hill, decide if it is too steep to
climb, descend, or cross. Steepness can be hard
to judge. On a very small hill, for example, there may be
a smooth, constant incline with only a small change in
elevation where you can easily see all the way to
the top. On a large hill, the incline may get steeper as
you near the top, but you might not see this because the
crest of the hill is hidden by bushes, grass, or shrubs.
Consider this as you approach a hill:
Is there a constant incline, or does the hill get
sharply steeper in places?
Is there good traction on the hillside, or will the
surface cause tire slipping?
Is there a straight path up or down the hill so you
will not have to make turning maneuvers?
Are there obstructions on the hill that can block your
path, such as boulders, trees, logs, or ruts?
What is beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and
walk the hill if you do not know. It is the smart way
to nd out.
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs, and exposed rocks because
they are more susceptible to the effects of erosion.
5-17

Driving Uphill
Once you decide it is safe to drive up the hill:
Use a low gear and get a rm grip on the steering
wheel.
Get a smooth start up the hill and try to maintain
speed. Not using more power than needed can
avoid spinning the wheels or sliding.
{CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.
Try to drive straight up the hill if at all possible. If
the path twists and turns, you might want to nd
another route.
Ease up on the speed as you approach the top of
the hill.
Attach a ag to the vehicle to be more visible to
approaching traffic on trails or hills.
Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
Use headlamps even during the day to make the
vehicle more visible to oncoming traffic.
{CAUTION:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.
If the vehicle stalls, or is about to stall, and you cannot
make it up the hill:
Push the brake pedal to stop the vehicle and keep
it from rolling backwards and apply the parking
brake.
If the engine is still running, shift the transmission to
R (Reverse), release the parking brake, and slowly
back down the hill in R (Reverse).
