2008 CADILLAC ESCALADE EXT transmission

Tow/Haul Mode
Your vehicle has a tow/haul mode. The tow/haul mode
adjusts the transmission shift pattern to reduce shift
cycling, providing increased performance, vehicle
control, and transmission cooling when towing or
hauling heavy loads.
Press the button located on the end of the shift lever
to turn the tow/haul on or off. When the tow/haul is on,
a light on the instrument panel cluster will come on.SeeTow/Haul Mode Light on page 3-44for more
information.
Also see “Tow Haul Mode” underTowing a Trailer
on page 4-43for more information.
The tow/haul mode works with the Autoride
®feature,
if the vehicle has this, to enhance the ride when trailering
or with a loaded vehicle. SeeAutoride
®on page 4-42.
Grade Braking
Grade Braking assists when driving on a downhill
grade. It maintains the vehicle’s speed by automatically
implementing a shift schedule that uses the engine
and the transmission to slow the vehicle. This reduces
wear on the brakes system and increases control of
the vehicle. The system constantly monitors the vehicle’s
speed, acceleration, throttle position, and whether the
brake pedal is being pressed, and determines when
to keep the current vehicle speed or to slow down.
The system will then automatically command downshifts
that reduces the vehicles speed, until the brake pedal
is no longer being pressed. This indicates the desired
vehicle speed has been reached.

The tow/haul mode and grade braking shift modes
can be activated by pressing the button on the end
of the shift control stalk. While in the DSC mode,
grade braking is deactivated, allowing the driver to
select a gear.
SeeAutomatic Transmission Operation on page 2-36
for more information.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.
A chime sounds and the warning light ashes when
the parking brake is applied and the vehicle is moving
at least 5 mph (8 km/h).To release the parking brake, hold the regular brake
pedal down. Then pull the bottom edge of the lever,
with the parking brake symbol and located above
the parking brake pedal.
If the ignition is on when the parking brake is released,
the brake system warning light goes off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-43.
2-41

Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle can put too much force on the parking pawl in the
transmission. It might be difficult to pull the shift lever out
of PARK (P). This is called torque lock. To prevent torque
lock, set the parking brake and then shift into PARK (P)
properly before you leave the driver’s seat. To nd out
how, seeShifting Into PARK (P) on page 2-42.
When you are ready to drive, move the shift lever out
of PARK (P) before releasing the parking brake.
If torque lock does occur, you might need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission.
Then you should be able to pull the shift lever out
of PARK (P).
Shifting Out of PARK (P)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in PARK (P) with the shift lever button
fully released, and
Prevent movement of the shift lever out of
PARK (P), unless the ignition is in ON/RUN or
ACC/ACCESSORY and the regular brake
pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-40for more
information.
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, press the
shift lever all the way into PARK (P).
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have
your vehicle serviced soon.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior lamps
control to the OFF position and then release. For
vehicles rst sold in Canada, the transmission must
be in the PARK (P) position, before the DRL lamps
can be turned off.
Automatic Headlamp System
When it is dark enough outside and the headlamp switch
is in AUTO, the automatic headlamp system will turn on
the headlamps at the normal brightness along with other
lamps such as the taillamps, sidemarker, parking lamps,
roof marker lamps, and the instrument panel lights.
The radio lights will also be dim.
To turn off the automatic headlamp system, turn
the exterior lamps switch to the off position and
then release. For vehicles rst sold in Canada, the
transmission must be in the PARK (P) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top
of the instrument panel. Be sure it is not covered,
or the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead
street lights does not affect the system. The DRL
and automatic headlamp system will only be affected
when the light sensor sees a change in lighting
lasting longer than the delay.

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner environment.
The check engine light
comes on to indicate
that there is an OBD II
problem and service
is required.
Malfunctions often are indicated by the system before
any problem is apparent. This can prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly diagnosing
any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, the emission controls
might not work as well, your vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by your warranty.Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This could
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.
This light comes on, as a check to show it is working,
when the ignition is turned ON/RUN but the engine is not
running. If the light does not come on, have it repaired.
This light also 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 your vehicle. Diagnosis and service might
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service might be required.
