2008 DODGE RAM 3500 GAS wheel

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.

Electronic Roll Mitigation (ERM)
The ERM system anticipates the potential for wheel lift
by monitoring the driver 's steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur.
²ERM cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. Only a safe,
attentive, and skillful driver can prevent accidents.
²The capabilities of an ERM-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
332 STARTING AND OPERATING

ESP (Electronic Stability Program)
The ESP system enhances directional control and stability
of the vehicle under various driving conditions. ESP
corrects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
Engine power may also be reduced to help the vehicle
maintain the desired path.
ESP uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The ªESP/TCS Indicator Lightº located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The ªESP/TCS Indicator Lightº also
flashes when TCS is active. If the ªESP/TCS Indicator
Lightº begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure
to adapt your speed and driving to the prevailing road
conditions.

WARNING!
²ESP (Electronic Stability Program) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
²ESP cannot prevent accidents, including those
resulting from excessive speed in turns, driving on
slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
²The capabilities of an ESP-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
The ESP system has multiple operating modes depend-
ing on vehicle type: Two-Wheel Drive (2WD) or Four-
Wheel Drive (4WD). 4WD vehicles may be equippedwith either a four-mode position (2WD/Neutral/4HI/
4LO) transfer case or a five-mode position (2WD/
AUTO/Neutral/4H/4LO) transfer case. If you have a
4WD vehicle, and want to determine which transfer case
is on your vehicle and how to operate it, refer to the
ªFour Wheel Drive Operatingº in Section 5.
All 2WD vehicles and 4WD vehicles in 2WD,
AUTO or 4HI Modes can choose the following ESP
operating modes:
ESP On
This is the normal operating mode for ESP in 2WD/
AUTO/4HI Modes and in 2WD vehicles. Whenever the
vehicle is started, or the transfer case (if equipped) is
shifted from 4LO or Neutral, back to 4HI or AUTO, the
ESP system will be in this mode. This mode should be
used for almost all driving situations. ESP should only be
turned to ªPartial Offº or ªESP Offº for specific reasons
as noted below.
334 STARTING AND OPERATING

ESP Partial Off
This mode is entered by momentarily depressing the
9ESP OFFº switch. When in9Partial Off9mode, the TCS
portion of ESP, except for the ªlimited slipº feature
described in the TCS section, has been disabled and the
9ESP/TCS Indicator Light9will be illuminated. All other
stability features of ESP function normally. This mode is
intended to be used if the vehicle is in deep snow, sand,
or gravel conditions and more wheel spin than ESP
would normally allow is required to gain traction. To
turn ESP on again, momentarily depress the9ESP OFFº
switch. This will restore the normal ªESP Onº mode of
operation.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial Offº
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the ªPartial Offº mode isovercome, turn ESP back on by momentarily depressing
the ªESP Control Switchº. This may be done while the
vehicle is in motion.
WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
All 4WD vehicles in Auto and 4HI Modes can also
choose the following ESP operating mode. This is
the only ESP operating mode in 4LO:
Full Off
This mode is intended for off-road use when ESP stability
features could inhibit vehicle maneuverability due to trail
conditions. This mode is entered by depressing and

ESP/BAS Warning Lamp and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ªESP/BAS Warning
Lampº and the yellow ªESP/TCS Indicator Lightº in the
instrument cluster both come on when the ignition
switch is turned to the ON position. They should both go
out with the engine running. If the ªESP/BAS Warning
Lampº comes on continuously with the engine running,
a malfunction has been detected in either the ESP or BAS
system, or both. If this light remains on after several
ignition cycles, and the vehicle has been driven several
miles/kilometers at speeds greater than 30 mph (48
km/h), see your authorized dealer as soon as possible to
have the problem diagnosed and corrected.
NOTE:
²The ªESP Indicator Lightº and the ªESP/BAS Warning
Lampº come on momentarily each time the ignition
switch is turned ON.
²Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
²The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal. The sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.
TSC (Trailer Sway Control)
The TSC system uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the appro-
priate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the
appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to ªTrailer Towingº in Section 5 of this manual for more
STARTING AND OPERATING 337

information on towing a trailer with your vehicle. When
TSC is functioning, the ªESP/TCS Indicator Lightº will
flash, the engine power may be reduced and you may
feel the brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is disabled
when the ESP system is in the Partial Off or Full Off
modes.
TSC is only active in the default ªESP Onº mode. TSC can
be disabled by pressing the ESP Off button and entering
ªESP Partial Offº mode. It is not active in the ªESP Partial
Offº or ªESP Offº modes. Please refer to the ESP portion
of this section for an explanation of the different ESP
operating modes.WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
MULTI-DISPLACEMENT SYSTEM (MDS) Ð 5.7L
ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine's eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
338 STARTING AND OPERATING

Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or six, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Compact Spare Tire Ð If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your stylevehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!
²Temporary use spare tires are for emergency use
only. With these tires, DO NOT drive more than 50
mph (80 km/h).
²Temporary-use spare tires have limited tread life.
When the tread is worn to the tread wear indica-
tors, the temporary use spare tire needs to be
replaced.
²Be sure to follow the warnings, which apply to
your spare. Failure to do so could result in spare
tire failure and loss of vehicle control.
