2020 Ram ProMaster City engine

194 STARTING AND OPERATING
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gearthat allows for adequate performance and avoids frequent
downshifts. For example, choose “5” if the desired speed
can be maintained. Choose “4” or “3” if needed to main -
tain the desired speed.
• To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear range or vehicle speed when grade and road condi -
tions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the Speed Control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use Speed Control in flat terrain and with light loads to maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over
-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

CAUTION!
• Always check the depth of the standing water before driving through it. Never drive through standing water
that is deeper than the bottom of the tire rims mounted
on the vehicle.
• Determine the condition of the road or the path that is under water and if there are any obstacles in the way
before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize wave effects.
• Driving through standing water may cause damage toyour vehicle’s drivetrain components. Always inspect
your vehicle’s fluids (i.e., engine oil, transmission, axle,
etc.) for signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through standing
water. Do not continue to operate the vehicle if any
fluid appears contaminated, as this may result in
further damage. Such damage is not covered by the
New Vehicle Limited Warranty.
• Getting water inside your vehicle’s engine can cause it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered by
the New Vehicle Limited Warranty. CAUTION!

JACKING AND TIRE CHANGING Jack Location — If Equipped
The jack and tools are stowed under the rear drivers front
seat or in the rear cargo area. It depends on the trim level.
Jack/Tools LocationWARNING!
• Do not attempt to change a tire on the side of the vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack
or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or slip -
pery areas.

The electric compressor will be turned on, sealant and air
will inflate the tire.
Minimum 26 psi (1.8 bar) of pressure should be reached
within 20 minutes. If the pressure has not been reached, turn
off and remove the Tire Service Kit, drive the vehicle 30 feet
(10 meters) back and forth, to better distribute the sealant
inside the tire.
Attach the clear flexible filling tube of the compressor
directly to the tire valve and repeat the inflation process.
When the correct pressure has been reached, start driving the
vehicle to uniformly distribute the sealant inside the tire.
After 10 minutes, stop and check the tire pressure. If the
pressure is below 19 psi (1.3 bar), do not drive the vehicle, as
the tire is too damaged, contact the nearest authorized
dealer.
