2018 Ram ProMaster wheel torque

When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as the
vehicle comes to a stop. This is the result of the system
reverting to the base brake system.
Engagement of the ABS may be accompanied by a pulsing
sensation. You may also hear a clicking noise. These
occurrences are normal and indicate that the system is
functioning properly.
Electronic Brake Control System
Your vehicle is equipped with an advanced electronic
brake control system that includes the Traction Control
System (TCS), Brake Assist System (BAS) and Electronic
Stability Control (ESC), Trailer Sway Control (TSC), and
Hill Start Assist (HSA). These systems complement the
Anti-Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneuvers.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount of
wheel spin of each of the driven wheels. If wheel spin is
detected, brake pressure is applied to the slipping wheel(s)
and engine power is reduced, to provide enhanced accel-
eration and stability. A feature of the TCS system, Brake
Limited Differential (BLD), functions similar to a limitedslip differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied to
the wheel that is not spinning. This feature remains active
even if the ESC is in the “Partial Off” mode.
The “ESC Activation/Malfunction Indicator Light” (in the
instrument cluster) will start to flash as soon as the tires
lose traction and the wheels begin to spin. This indicates
that the TCS is active. If the indicator light flashes 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, and do not
switch off the ESC or TCS.
WARNING!
•
The TCS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.
• The TCS cannot prevent collisions, including those
resulting from excessive speed in turns, or hydro-
planing.

will be in this mode. This mode should be used for most
driving situations. ESC should only be turned off for
specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pushing the “ESC
Off” switch.
When in the “Partial Off” mode, the TCS portion of ESC,
except for the “limited slip” feature described in the TCS
section, has been disabled and the “ESC OFF Indicator
Light” will be illuminated. When in the “Partial Off” mode,
ESC will operate without engine torque management. This
mode is intended to be used if the vehicle is in deep snow,
sand or gravel conditions and more wheel spin than ESC
would normally allow is required to gain traction. To turn
ESC on again, momentarily push the “ESC Off” switch.
This will restore the normal “ESC On” mode of operation.
WARNING!
•When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature described
in the TCS section), has been disabled and the “ESC
Off Indicator Light” will be illuminated. When in

WARNING! (Continued)
“Partial Off” mode, the engine power reduction
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.
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 pushing the “ESC Off” switch. Once the situation
requiring ESC to be switched to the “Partial Off” mode is
overcome, turn ESC back on by momentarily pushing the
“ESC Off” switch. This may be done while the vehicle is in
motion.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is turned to the ON mode. It should go
out with the engine running. If the ESC
Activation/Malfunction Indicator Light comes on continu-
ously with the engine running, a malfunction has been
92 SAFETY

NOTE:
•The torque converter clutch will not engage, until the
transmission fluid and engine coolant are warm [usually
after 1 to 3 miles (2 to 5 km) of driving]. Because the
engine speed is higher when the torque converter clutch
is not engaged, it may seem as if the transmission is not
shifting into Overdrive when cold. This is normal. Using
the Electronic Range Select (ERS) shift control, when the
transmission is sufficiently warm, will demonstrate that
the transmission is able to shift into and out of Over-
drive.
• If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the transmis-
sion into gear may seem sluggish. This is due to the fluid
partially draining from the torque converter into the
transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds after starting the engine.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost. If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•
Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This
is due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in
any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.

WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
NOTE: Do not install the wheel cover on the spare tire.
7. Lower the vehicle by turning the jack screw to the left.
8. Refer to “Wheel And Tire Torque Specifications” in “Technical Specifications” for proper wheel lug bolt
torque.
9. Lower the jack to its fully-closed position.
10. Stow the damaged wheel/spare tire with the cable and wheel spacer before driving the vehicle.
11. Install the winch extension and rotate the wrench
handle clockwise until the winch mechanism opera-
tor hears “3 clicks” from the device to indicate the
wheel is properly stowed under the vehicle.
12. Stow the jack, jack handle and winch handle tools back in the storage compartment.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the
left front corner of the instrument panel, visible through
the windshield. This number also appears on the vehicle
frame and underbody as well as the Automobile Informa-
tion Disclosure Label affixed to a window on your vehicle,
the vehicle registration and title.
NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the “Brake System Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles. Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half-
way).
After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
