2009 CADILLAC ESCALADE ESV trailer

When the System Does Not Seem to
Work Properly If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 6-100 .
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the liftgate during the
last drive cycle, the red light may illuminate in the
rear display. Once the attached object is removed,
URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at least
15 mph (25 km/h), take the vehicle to your dealer/retailer. Side Blind Zone Alert (SBZA) The vehicle may have a Side Blind Zone Alert (SBZA)
system. Read this entire section before using the system.

The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modications to
this equipment. Such modications could void the user’s
authority to operate the equipment.
{ CAUTION: SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
Vehicles outside the side blind zones which
may be rapidly approaching.
Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanes
may result in damage to the vehicle, injury, or
death. Always check the outside and rearview
mirrors, glance over your shoulder, and use the
turn signal before changing lanes.
When the system detects a vehicle in the side blind zone,
amber SBZA displays light up in the side mirrors. This
indicates that it may be unsafe to change lanes. Before
making a lane change, always check the SBZA display,
check the outside and rearview mirrors, look over your
shoulder for vehicles and hazards, and use the turn
signal. SBZA Detection Zones The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 11 ft. or 3.5 m.
This zone starts at each side mirror and goes back
approximately 16 ft. (5.0 m). The height of the zone is
approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off
the ground.
Use caution while changing lanes when towing a trailer,
as the SBZA detection zones do not change when a
trailer is towed.
2-45

SBZA does not operate when the left or right corners
of the rear bumper are covered with mud, dirt, snow,
ice, slush, or in heavy rainstorms. For cleaning
instructions, see Washing Your Vehicle on page 6-100 .
If the DIC still displays the SIDE BLIND ZONE SYSTEM
UNAVAILABLE message after cleaning the bumper, see
your dealer/retailer.
The SBZA displays may remain on if a trailer is attached
to the vehicle, or a bicycle or object is extending out
to either side of the vehicle.
When SBZA is disabled for any reason other than the
driver turning it off, the driver will not be able to turn SBZA
back on using the DIC. The SIDE BLIND ZONE ALERT
ON option will not be selectable if the conditions for
normal system operation are not met. Until normal
operating conditions for SBZA are met, you should not
rely upon SBZA while driving. SBZA Error Messages The following messages may appear in the DIC:
SIDE BLIND ZONE ALERT SYSTEM OFF: This
message indicates that the driver has turned the
system off.
SIDE BLIND ZONE SYSTEM UNAVAILABLE: This
message indicates that the SBZA system is disabled
either because the sensor is blocked and cannot detect
vehicles in your blind zone, or the vehicle is passing
through an open eld of view area, such as the desert,
where there is insufficient data for operation. The sensor
may be blocked by mud, dirt, snow, ice, slush, or even
heavy rainstorms. This message may also activate during
heavy rain or due to road spray. The vehicle does not
need service. For cleaning, see Washing Your Vehicle on
page 6-100 .
SERVICE SIDE BLIND ZONE ALERT SYSTEM: If this
message appears, both SBZA displays will remain on
indicating there is a problem with the SBZA system.
If these displays remain on after continued driving, the
system needs service. Take the vehicle to your
dealer/retailer.

Reading Lamps If the vehicle has reading lamps, press the button
located next to the lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps cannot be adjusted.
Electric Power Management The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not
be spinning fast enough at idle to produce all the
power that is needed for very high electrical loads. A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase engine
idle speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. See DIC
Warnings and Messages on page 3-56 .

This light comes on during a malfunction in one of
two ways:
Light Flashing: A misre condition has been detected.
A misre increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still ashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
Light On Steady: An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required. An emission system malfunction might be corrected by
doing the following:
Make sure the fuel cap is fully installed. See Filling
the Tank on page 6-9 . The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
If the vehicle has been driven through a deep puddle
of water, the vehicle’s electrical system might be wet.
The condition is usually corrected when the electrical
system dries out. A few driving trips should turn the
light off.
Make sure to fuel the vehicle with quality fuel. Poor
fuel quality causes the engine not to run as efficiently
as designed and can cause: stalling after start-up,
stalling when the vehicle is changed into gear,
misring, hesitation on acceleration, or stumbling
on acceleration. These conditions might go away
once the engine is warmed up.
If one or more of these conditions occurs, change the
fuel brand used. It will require at least one full tank of
the proper fuel to turn the light off.
See Gasoline Octane on page 6-5 .
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
x any mechanical or electrical problems that might have
developed.

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.
See Tow/Haul Mode on page 2-33 for 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
ride and handling characteristics when the vehicle is
loaded or towing a trailer. See “Tow/Haul Mode” under
Towing a Trailer on page 5-44 .
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 If the vehicle has this feature, engine power is sent to all
four wheels when extra traction is needed. 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.
If the vehicle is a Two-mode Hybrid, see “Four-Wheel
Drive” in the Two-mode Hybrid Supplement.

Steps for Determining Correct Load Limit 1.
Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle’s placard.2.
Determine the combined weight of the driver
and passengers that will be riding in your
vehicle.3.
Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.4.
The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs (1400 − 750 (5 x 150) = 650 lbs). 5.
Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated in
Step 4. 6.
If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity of your vehicle. See Towing a
Trailer on page 5-44 for important information
on towing a trailer, towing safety rules and
trailering tips.
