Battery Blanket Usage

A battery loses 60% of its cranking power as the battery

temperature decreases to 0°F (-18°C). For the same de-

crease in temperature, the engine requires twice as much

power to crank at the same RPM. The use of 120 VAC

powered battery blankets will greatly increase starting

capability at low temperatures. Suitable battery blankets

are available from your authorized MOPAR® dealer.

Engine Warm-Up

Avoid full throttle operation when the engine is cold.

When starting a cold engine, bring the engine up to

operating speed slowly to allow the oil pressure to

stabilize as the engine warms up.

NOTE: High-speed, no-load running of a cold engine

can result in excessive white smoke and poor engine

performance. No-load engine speeds should be kept

under 1,200 RPM during the warm-up period, especially

in cold ambient temperature conditions.

Your vehicle is equipped with a turbo speed limiter, this

feature limits the engine speed to 1,200 RPM when

engine coolant temperatures are below 70°F (21°C). This

feature is designed to protect the turbocharger from

damage and will only operate in PARK or NEUTRAL.

If temperatures are below 32°F (0°C), operate the engine

at moderate speeds for five minutes before full loads are

applied.
