PARKVIEW REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView Rear
Back Up Camera that allows you to see a image of the
rear surroundings of your vehicle whenever the gear
selector is put into REVERSE or whenever it is initiated
through  Backup Camera  button in the  Controls  menu.
Whenever the gear selector is put into REVERSE, the
image will be displayed in the rearview mirror display (if
equipped) or Uconnect screen (if equipped) along with a
caution note to “check entire surroundings” across the
top of the screen. After five seconds this note will
disappear. NOTE: For the 3500, 4500 and 5500 Chassis Cab vehicles,
the Rear Backup Camera is shipped loose and not
installed. Please Refer to the Ram Body Builders Guide
for more information.
The ParkView camera is located to the left of the tailgate
handle.
When the vehicle is shifted out of REVERSE (with camera
delay turned OFF), the rear camera mode is exited and
the navigation or audio screen appears again.
When the vehicle is shifted out of REVERSE (with camera
delay turned ON), The rear camera image will be dis-
played for up to 10 seconds after shifting out of  RE-
VERSE  unless the forward vehicle speed exceeds 8 mph
(13 km/h), the transmission is shifted into  PARK  or the
ignition is switched to the OFF position.
Whenever the Rear View Camera image is activated
through  Backup Camera  button in the  Controls  menu, 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 205

Tire Pressure Monitoring Indicator Light
Yellow Telltale
Light What It Means
Tire Pressure Monitoring Indicator Light
The warning light switches on and a message is displayed to indicate that the tire pressure
is lower than the recommended value and/or that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the
indications corresponding to each tire in sequence.
IMPORTANT: Do not continue driving with one or more
flat tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. Repair
immediately using the dedicated tire repair kit and
contact your authorized dealership as soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when254 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size, (Continued) CAUTION! (Continued)type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.256 UNDERSTANDING YOUR INSTRUMENT PANEL

The 4H and 4L positions are intended for loose, slippery
road surfaces only. Driving in the 4H and 4L positions on
dry, hard surfaced roads may cause increased tire wear
and damage to the driveline components.
The “Transfer Case Position Indicator Light” in the
instrument cluster will alert the driver that the vehicle is
in four-wheel drive and that the front and rear drive-
shafts are locked together. This light will illuminate when
the transfer case is shifted into either the 4H or 4L
position. There is no light for the 2H or NEUTRAL
positions on some models.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H 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 four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference will adversely affect shifting and
can cause damage to the drivetrain.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. The front and rear
driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
NOTE: Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold tempera-
tures.424 STARTING AND OPERATING

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).

WARNING!You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the (Continued) WARNING! (Continued)NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position, see the information below:

WARNING! (Continued)accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent acci-
dents. The capabilities of an ESC equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety or
the safety of others.
• Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect (Continued) WARNING! (Continued)ESC performance. Improperly inflated and un-
evenly worn tires may also degrade ESC perfor-
mance. Any vehicle modification or poor vehicle
maintenance that reduces the effectiveness of the
ESC system can increase the risk of loss of vehicle
control, vehicle rollover, personal injury and death.
ESC Operating Modes
NOTE: Depending upon model and mode of operation,
the ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used for
specific reasons as noted in the following paragraphs. 5STARTING AND OPERATING 451
