Cold Weather Operation
To prevent possible engine damage while starting at low
temperatures, this vehicle will inhibit engine cranking
when the ambient temperature is less than –22° F (–30° C)
and the oil temperature sensor reading indicates an
engine block heater has not been used. An externally-
powered electric engine block heater is available as
optional equipment or from your authorized dealer.
The messageplug in engine heater will be displayed in the
instrument cluster when the ambient temperature is below
5° F (–15° C) at the time the engine is shut off as a reminder
to avoid possible crank delays at the next cold start.
CAUTION!
Use of the recommended SAE 5W-30 oil and adher-
ing to the prescribed oil change intervals is important
to prevent engine damage and ensure satisfactory
starting in cold conditions.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle.

Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of Chrysler Material
Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade)
SAE 5W-30 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also states the recommended engine oil viscosity
grade for your engine.
Lubricants which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
