2007 DODGE RAM 1500 GAS Owners Manual

ESP/TCS Indicator Light
The “ESP/TCS Indicator Light” located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The “ESP/TCS Indicator Light” also
flashes when TCS is active. If the “ESP/TCS Indicator
Light” 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!
•ESP (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.
•ESP 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.
•The 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.
STARTING AND OPERATING 353

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 equipped
with 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, refer to the Four Wheel Drive Operating Section
to determine which transfer case is on your vehicle and
how to operate it.
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 usedfor almost all driving situations. ESP should only be
turned to “Partial Off” or “ESP Off” for specific reasons
as noted below.
This mode is entered by momentarily
depressing the “ESP Control Switch”.
When in “Partial Off” mode, the TCS
portion of ESP, except for the “limited
slip” feature described in the TCS sec-
tion, has been disabled and the “ESP/
TCS Indicator Light” will be illumi-
nated. All other features of ESP function normally, with
the exception of engine power reduction. Engine power
is not reduced in this mode. 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 nor-
mally allow is required to gain traction. To turn ESP on
again, momentarily depress the “ESP Control Switch”.
This will restore the normal “ESP On” mode of operation.
354 STARTING AND OPERATING

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 “Partial Off”
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the “ESP Control Switch”. 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:
ESP 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
holding the “ESP Control Switch” for 5 seconds when the
vehicle is stopped and the engine is running. After 5
seconds, the “ESP/TCS Indicator Light” will illuminate
and the “ESP Off” message will appear in the odometer.
Press and release the trip odometer button located on the
instrument cluster to clear this message.
In this mode, ESP and TCS, except for the “limited Slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At 40
mph (64 km/h) the system returns to “Partial Off” mode,
described above. When the vehicle speed drops below 35
STARTING AND OPERATING 355
5

mph (56 km/h) the ESP system shuts off. ESP is off at low
vehicle speeds sao that it will not interfere with off-road
driving but ESP function returns to provide the stability
feature at speeds above 40 mph (64 km/h). The “ESP/
TCS Indicator Light” will always be illuminated when
ESP is off. To turn ESP on again, momentarily depress the
“ESP Control Switch”. This will restore the normal “ESP
On’ mode of operation.
“ESP Off” is the only operating mode for ESP in 4LO.
Whenever the vehicle is started in 4LO or the transfer
case (if equipped) is shifted from 4HI or neutral to 4LO,
the ESP system will be in this mode.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. “ESP Off”
mode is intended for off-highway or off-road use,
only.
ESP/BAS Warning Lamp and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow “ESP/BAS Warning
Lamp” and the yellow “ESP/TCS Indicator Light” 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 “ESP/BAS Warn-
ing Lamp” comes on continuously with the engine
running, a malfunction has been detected in either the
356 STARTING AND OPERATING

ESP or BAS system, or both. If this light remains on after
several ignition cycles, and the vehicle has been driven
several miles 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:
•The “ESP Indicator Light” and the “ESP/BAS Warning
Lamp” come on momentarily each time the ignition
switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The 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.
MULTI DISPLACEMENT SYSTEM (MDS) - 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.

TIRE SAFETY INFORMATION
Tire Markings
NOTE:
•P (Passenger)-Metric tire sizing is based on U.S. design
standards. P-Metric tires have the letter “P” molded
into the sidewall preceding the size designation. Ex-
ample: P215/65R15 95H.
•European Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letterPis absent from this tire
size designation. Example: 215/65R15 96H
•LT (Light Truck)-Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary Spare tires are high-pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•High Flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.
