Drivability
Diesel engines are controlled by a PCM (Pow-
ertrain Control Module). With state of the art
technology and emissions regulations, vehicles
may perform differently from one model year to
another.
Drivability can also be affected by the following:
• After-treatment regeneration
• Two footed driving (if brake pedal and accel-
erator are pressed at the same time, you will
notice a delay in power).
• Temperature
• Weather
• Wind
• Load
• Altitude
• Gear Ratio
These conditions are considered natural events
and may not be corrected. If at any time the
check engine light is on, please visit an autho-
rized dealer.
Fuel Economy
Diesel engines offer superb fuel economy under
certain conditions. Fuel economy should im-
prove after the vehicle is broke in. Many factors
will affect or reduce fuel economy.
• After-treatment Regeneration
• Cold Temperatures
• Wind
• Extended Idling
• Towing
• Short Trips
• Fuel Quality
• City Driving
• Aftermarket Grills
• Oversized Tires
• Gear Ratios
If at any time your check engine light is on,
please visit an authorized dealer.
DIESEL ENGINE STARTING
• Your RAM is equipped with state-of-the-art
ceramic glow plugs to ensure quick starts.
• Some delay of engine cranking may occur
while the glow plugs reach operating tem-
perature. The length of time will vary from
1 to 5 seconds depending on the engine and
ambient temperatures.
• Remote start operation of your vehicle will
also automatically activate the glow plugs as
needed and no additional steps are required,
you may experience a delay in starting when
using remote start.
