2009 RAM CHASSIS CAB ECU

Tire Size
The tire size on the Label represents the actual tire size on
your vehicle. Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over front and rear axle. Weighing
the vehicle may show that the GAWR of either the front
or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
288 STARTING AND OPERATING

NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options, or authorized dealer-installed
options must be considered as part of the total load on
your vehicle. Refer to “Tire and Loading Information
placard” under “Tire Safety Information” in Section 5.
Towing Requirements
To promote proper break-in of your new vehicle drive-
train components, the following guidelines are recom-
mended:
CAUTION!
•Avoid towing a trailer for the first 500 miles
(805 km) of vehicle operation. Doing so may dam-
age your vehicle.
•During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h). Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.

WARNING! (Continued)
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning Flasher.1. If equipped, remove the spare wheel, jack, and tools
from storage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. When changing the front wheel, assemble the jack
drive tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle as close to
the tire as possible with the drive tubes extending to the
front. Connect the jack tube extension and wheel wrench.
Jack Warning Label
318 WHAT TO DO IN EMERGENCIES

When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Securely place the jack under the sway
bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing forward in vehicle.
Connect the jack tube extension and lug wrench.Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the
jack drive tube in order to lower the jack.
