RAM C/V (2013 year). Instruction — part 32

HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.

WARNING!

There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.

Disabling/Enabling HSA

If you wish to turn on or off the HSA system, it can be
done using the Customer Programmable Features in the
Electronic Vehicle Information Center (EVIC). Refer to

“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.

For vehicles not equipped with the EVIC, perform the
following steps:

NOTE:

You must complete Steps 1 through 8 within 90

seconds.

1. Center the steering wheel (front wheels pointing

straight forward).

2. Shift the transmission into NEUTRAL.

3. Apply the parking brake.

4. Start the engine.

5. Release the clutch pedal (if equipped).

6. Rotate the steering wheel one-half turn to the left.

STARTING AND OPERATING

7. Press the “ESC Off” switch (located in the lower

switch bank below the climate controls) four times
within 20 seconds. The “ESC Activation/Malfunction
Indicator Light” should turn on and turn off two
times.

8. Rotate the steering wheel back to center and then an

additional half-turn to the right.

9. Turn the ignition switch to the OFF position and then

back to the ON position. If the sequence was com-
pleted properly, the “ESC Activation/Malfunction In-
dicator Light” will blink several times to confirm HSA
is disabled.

10. Repeat these steps if you want to return this feature

to it’s previous setting.

Towing With HSA

HSA will provide assistance when starting on a grade
when pulling a trailer.

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 behind you. In order to avoid
rolling down the hill while resuming acceleration,
instructionly activate the trailer brake prior to releas-
ing the brake pedal. Always remember the driver is
responsible for braking the vehicle.

WARNING! (Continued)

• HSA is not a parking brake. If you stop the vehicle

on a hill without putting the transmission in PARK
and using the parking brake, it will roll down the
hill and could cause a collision with another ve-
hicle or object. Always remember to use the park-
ing 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, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.

Tire Terminology And Definitions

Term

Definition

B-Pillar

The vehicle B-Pillar is the structural member of the body located
behind the front door.

Cold Tire Inflation Pressure

Cold tire inflation pressure is defined as the tire pressure after
the vehicle has not been driven for at least 3 hours, or driven less
than 1 mile (1.6 km) after sitting for a three hour period. Inflation
pressure is measured in units of PSI (pounds per square inch) or
kPa (kilopascals).

Maximum Inflation Pressure

The maximum inflation pressure is the maximum permissible
cold tire inflation pressure for this tire. The maximum inflation
pressure is molded into the sidewall.

Recommended Cold Tire Inflation Pres-

sure

Vehicle manufacturer’s recommended cold tire inflation pressure
as shown on the tire placard.

Tire Placard

A paper label permanently attached to the vehicle describing the
vehicle’s loading capacity, the original equipment tire sizes and
the recommended cold tire inflation pressures.

3) tire size designed for your vehicle
4) cold tire inflation pressures for the front, rear, and
spare tires.

Loading

The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire and Loading
Information placard and in the “Vehicle Loading” section
of this instruction.

NOTE:

Under a maximum loaded vehicle condition,

gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in this section.

To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.

Steps For Determining Correct Load Limit

1. Locate the statement “The combined weight of occu-

pants and cargo should never exceed XXX lbs or
XXX kg” 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 pas-

sengers from XXX lbs or XXX kg.

5

STARTING AND OPERATING

511

4. The resulting figure equals the available amount of

cargo and luggage load capacity. For example, if
“XXX” amount equals 1,400 lbs (635 kg) and there will
be five 150 lb (68 kg) passengers in your vehicle, the
amount of available cargo and luggage load capacity
is 650 lbs (295 kg) (since 5 x 150 = 750, and 1400 – 750
= 650 lbs [295 kg]).

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, load from your

trailer will be transferred to your vehicle. Consult this
instruction to determine how this reduces the available
cargo and luggage load capacity of your vehicle.

NOTE:

• The following table shows examples on how to calcu-

late total load, cargo/luggage, and towing capacities
of your vehicle with varying seating configurations
and number and size of occupants. This table is for
illustration purposes only and may not be accurate for
the seating and load carry capacity of your vehicle.

• For the following example, the combined weight of

occupants and cargo should never exceed 865 lbs
(392 kg).

WARNING!

Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.

TIRES — GENERAL INFORMATION

Tire Pressure

Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:

Safety

WARNING!

• Improperly inflated tires are dangerous and can

cause collisions.

• Under-inflation increases tire flexing and can re-

sult in over-heating and tire failure.

• Over-inflation reduces a tire’s ability to cushion

shock. Objects on the road and chuckholes can
cause damage that result in tire failure.

• Over-inflated or under-inflated tires can affect ve-

hicle handling and can fail suddenly, resulting in
loss of vehicle control.

• Unequal tire pressures can cause steering prob-

lems. You could lose control of your vehicle.

(Continued)

514

STARTING AND OPERATING

WARNING! (Continued)

• Unequal tire pressures from one side of the vehicle

to the other can cause the vehicle to drift to the
right or left.

• Always drive with each tire inflated to the recom-

mended cold tire inflation pressure.

Economy

Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-inflation also increases
tire rolling resistance resulting in higher fuel consump-
tion.

Ride Comfort And Vehicle Stability

Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride. Both under-inflation and over-inflation affect the
stability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the steering.

Unequal tire pressures from side to side may cause erratic
and unpredictable steering response.

Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
