warning light DODGE RAM 2500 GAS 2008 3.G Owner's Manual

WARNING!
Always engage the parking brake when powering
down the vehicle if the(SERVICE 4WD(light is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning, as this can cause
damage to driveline components.When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the
transfer case.
Because 4-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.

slippery surface, a slight application of the accelerator
will supply maximum traction. When starting with only
one rear wheel on an excessively slippery surface, slight
momentary application of the parking brake may be
necessary to gain maximum traction.
WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground, since the vehicle may drive through the rear
wheel remaining on the ground. You could lose
control of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
DRIVING ON SLIPPERY SURFACES
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the car in front to avoid a collision in a sudden stop.
314 STARTING AND OPERATING

CAUTION!
²Driving through standing water may cause dam-
age to your vehicle's drivetrain components. Al-
ways inspect your vehicle's fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
²Getting water inside your vehicle's engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
²Driving through standing water limits your vehi-
cle's traction capabilities. Do not exceed 5 mph (8
km/h) when driving through standing water.
²Driving through standing water limits your vehi-
cle's braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
²Getting water inside your vehicle's engine can
cause it to lock up and stall out, and leave you
stranded.
²Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
316 STARTING AND OPERATING

PARKING BRAKE
The foot-operated parking brake is positioned below the
lower left corner of the instrument panel. To release the
parking brake, pull the parking brake release handle.
NOTE:The instrument cluster red brake warning light
will come on and flash to indicate that the parking brake
is applied. You must be sure that the parking brake is
fully applied before leaving the vehicle.
Be sure the parking brake is firmly set when parked and
the shift lever is in the PARK position. When parking on
a hill you should apply the parking brake before placing
the shift lever in PARK, otherwise the load on the
transmission locking mechanism may make it difficult to
move the shift lever out of PARK.

318 STARTING AND OPERATING

WARNING!
Both Rear-Wheel and Four-Wheel Anti-Lock Brake
Systems contain sophisticated electronic equipment.
It may be susceptible to interference caused by
improperly installed or high output radio transmit-
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
Four-Wheel Anti-Lock Brake System Ð If
Equipped
This Four-Wheel Anti-lock Brake System (ABS) is de-
signed to aid the driver in maintaining vehicle control
under adverse braking conditions. The system operateswith a separate computer to modulate hydraulic pressure
to prevent wheel lockup and help avoid skidding on
slippery surfaces.
The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.
The ABS conducts a low-speed selftest at about 10 mph
(16 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
The ABS pump motor runs during the self-test at 10 mph
(16 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation. This is
normal.
STARTING AND OPERATING 321

When you are in a severe braking condition involving
use of the ABS, you will experience some pedal drop as
the vehicle comes to a complete stop. This is the result of
the system reverting to the base brake system and is
normal.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal, and indicate that the
system is functioning.
ABS Warning Light
The ABS includes an amber warning light. When the light
is illuminated, the ABS is not functioning. The system
reverts to standard, non-anti-lock brakes.
WARNING!
Pumping of the anti-lock brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
322 STARTING AND OPERATING

HSA (Hill Start Assist)
The HSA system is designed to assist the driver in
launching a vehicle on an incline. HSA will maintain the
level of brake pressure the driver inputs for a short
duration once the driver takes his foot off of the brake
pedal. If the driver does not apply the throttle during this
short duration, the system will release brake pressure
and the vehicle will roll down the incline. The system will
release brake pressure in proportion to the amount of
throttle applied.
During operation, Hill Start Assist will activate the brake
control system and a clicking noise will occur. If your foot
is on the brake pedal during operation you may feel a
slight pedal movement. The clicking and pedal move-
ment is normal and both will stop when HSA becomes
inactive.WARNING!
If the clutch pedal (manual vehicles only) remains
depressed during the application of the throttle, the
HSA will disengage allowing the vehicle to roll
down the incline. This could cause a collision with
another vehicle or object. To avoid this, do not apply
throttle while depressing the clutch pedal until you
are ready to release the clutch. Always remember the
driver is responsible for braking the vehicle.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
²Vehicle must be stopped
²Vehicle must be on a 7% or greater incline
328 STARTING AND OPERATING

²Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills (i.e., less than
7%), with a loaded vehicle, or while pulling a trailer
where the system will not activate and slight rolling
may occur, which could cause a collision with an-
other vehicle or object. Always remember the driver
is responsible for braking the vehicle.
The system will only work if the intended direction of the
vehicle and vehicle gear match. For example, if the
intended direction is forward up a hill and the vehicle is
in drive (automatic equipped vehicle), and the activation
criteria are met, HSA will activate.
HSA on Automatic Vehicles
The system will work in REVERSE and all forward gears
on vehicles equipped with an automatic transmission.
The system will not activate if the vehicle is placed in
neutral.
HSA on Manual Vehicles
The system will work in REVERSE, forward gears, and
NEUTRAL on manual transmission equipped vehicles.
The system does not recognize NEUTRAL on manual
vehicles, thus it will hold the vehicle on an incline for a
short period while in NEUTRAL, regardless of clutch
position. To prevent this, do not attempt to roll down a
hill simply by putting the transmission in NEUTRAL and
letting gravity act on the vehicle, as the HSA will prevent
the vehicle from rolling. Instead, use the appropriate gear
for moving in the desired direction.

Towing and Hauling with HSA (Vehicles Equipped
with Automatic Transmissions Only)
The HSA system does not know if your vehicle is loaded
or towing a trailer, unless the TOW/HAUL button,
located on the transmission gear shift lever, is selected.
When activated, the TOW/HAUL light will illuminate in
the instrument cluster. For more information on TOW/
HAUL mode, refer to ªWhen To USE TOW/HAUL and
O/D OFF Modesº under9Automatic Transmissionº in
Section 5. In order to accommodate the extra weight
entailed under towing and hauling conditions and to
increase driver comfort while launching on a hill, the
system recognizes when the TOW/HAUL button is acti-
vated and compensates by releasing brake pressure at a
slower rate while throttle is applied in order to prevent
the vehicle from rolling down the hill.
WARNING!
If you use a trailer brake controller with your trailer,
your trailer brakes may be activated and deactivated
with the brake switch. If so, when the brake pedal is
released, there may not be enough brake pressure to
hold the vehicle and trailer on a hill and this could
cause a collision with another vehicle or object be-
hind you. In order to avoid rolling down the incline
while resuming acceleration, manually activate the
trailer brake or apply more vehicle brake pressure
prior to releasing the brake pedal. Always remember
the driver is responsible for braking the vehicle.
330 STARTING AND OPERATING

WARNING!
HSA is not a parking brake. If you stop the vehicle on
a hill without putting the transmission in PARK or
using the parking brake, it will roll down the incline
and could cause a collision with another vehicle or
object. Always remember to use the parking brake
while parking on a hill, and that the driver is
responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, follow this
procedure:
1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply park-
ing brake on manual transmission vehicle.2. Start the engine.
3. With the engine running, the brake applied, and the
clutch out, rotate the steering wheel 180É counterclock-
wise from center.
4. Press ESP button four times within twenty seconds.
The ªESP/TCS Indicator Lightº should appear and dis-
appear four times.
5. Rotate the steering wheel 360É clockwise (180É clock-
wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the ªESP/
TCS Indicator Lightº will blink several times to confirm
HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.
