warning light Ram 2500 2011 Owner's Guide

28. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
29. Anti-Lock Brake (ABS) Light
This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.30. Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.

WARNING!
Continued operation with the Transmission Tem-
perature Warning Light illuminated could cause the
fluid to boil over, come in contact with hot engine or
exhaust components causing a fire that may result in
personal injury.
For vehicles equipped with a premium cluster this warn-
ing light will display in the Electronic Vehicle Informa-
tion Center (EVIC). Refer to ”Electronic Vehicle Informa-
tion Center (EVIC) — If Equipped” for further
information.
31. Seat Belt Reminder Light
When the ignition switch is first turned to ON/
RUN, this light will turn on for five to eight
seconds as a bulb check. During the bulb check, if
the driver’s seat belt is unbuckled, a chime will sound.
After the bulb check or when driving, if the driver’s seatbelt remains unbuckled, the seat belt reminder light will
flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
32. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on
briefly as a bulb check. If the light stays on or comes on
while driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.

continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information.
•SERV 4WD

STARTING AND OPERATING 303

Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fourth gear (OVERDRIVE). The
transmission will automatically shift from third gear to
OVERDRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL switch has not been activated
•the transmission has reached normal operating
temperature
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE and will automatically select the most desirablegear for operation at this temperature. Normal operation
will resume when the transmission fluid temperature has
risen to a suitable level.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After the transmission cools
down, the transmission will resume normal operation.
The transmission will downshift from OVERDRIVE to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch. This will improve

through third gear are underdrive gears, and fourth gear
is direct drive. ERS fifth gear (Overdrive) is the same as
the normal fourth gear.
When in the DRIVE position in first through fourth gear,
the first tap down (-), will display the ERS designation for
the current gear (the transmission will not downshift).
For example, if you are in DRIVE and are in third (direct)
gear, when you tap the shift lever/switch one time in the
(-) direction, the display will show 4 (ERS 4 is direct gear).
Another tap down (-) will shift the transmission down to
ERS 3 (the added underdrive gear). When in the DRIVE
position in fifth gear, the first tap down (-) will downshift
the transmission and display 5 (ERS 5 is the same as
normal fourth gear). Another tap down (-) will shift the
transmission down to ERS 4 (direct gear).
To exit ERS mode, press and hold the shift lever/switch
in the (+) position until “D” is once again highlighted in
the instrument cluster display.WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.

in the (-) position continuously while braking. The trans-
mission will shift to the range from which the vehicle can
best be slowed down.
318 STARTING AND OPERATING

Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth gear (Overdrive).
The transmission will automatically shift from DRIVE to
Overdrive if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant (antifreeze) has reached normal
operating temperature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the TOW/HAUL switch has not been activated;
•transmission has reached normal operating
temperature.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear foroperation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of Overdrive until the
transmission cools down. After cool down, the transmis-
sion will resume normal operation.
The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
