2015 Ram ProMaster wheel torque

•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission 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 con-
verter will refill within five seconds after starting the
engine.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the front (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have a collision. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when the roads are
slushy.

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.
(Continued)
WARNING! (Continued)
•The TCS cannot prevent collisions, including those
resulting from excessive speed in turns, or hydro-
planing.
• The capabilities of a TCS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize
the vehicle’s braking capability during emergency brak-
ing maneuvers. The system detects an emergency brak-
ing situation by sensing the rate and amount of brake
application, and then applies optimum pressure to the
brakes. This can help reduce braking distances. The BAS
complements the ABS. Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure

mode, ESC will operate without engine torque manage-
ment. 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 inPartial 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 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 Offmode. 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 situa-
tion 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 switch is turned to the ON
position. It should turn off with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
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 calibrated torque wrench.

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.

WHAT TO DO IN EMERGENCIES 289

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.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to 1/4 inch (6 mm) in the tire tread
can be sealed with Tire Service Kit. Foreign objects (e.g.,
screws or nails) should not be removed from the tire. Tire
Service Kit can be used in outside temperatures down to
approximately -4°F (-20°C).
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (90 km/h).

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.
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 personal injury.
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 “Torque Specifications” in this section 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.
