If you regularly drive your vehicle in
very cold weather [below
4°F
(
20°C)], consider having an
engine block heater installed. It
should greatly improve starting in
very cold weather.
Also, when driving in very cold
weather, make sure that the 12 V
battery is fully charged either by
driving several miles each day or by
using a 12 V charger to fully charge
the battery.
An engine is harder to start in cold
weather. The thinner air found at
high altitude above 5,000 feet (1,600
meters) adds to the problem.
The unique design of a CNG engine
makes it even more difficult or
impossible to start if temperatures
drop below 4°F (
16°C).
Turn off all electrical accessories
to reduce the drain on the battery.
Make sure the malfunction
indicator lamp goes out before you
turn the ignition switch to the
START (III) position.
Push the accelerator pedal half-
way to the floor and hold it there
while starting the engine. Do not
hold the ignition switch in the
START (III) position for more
than 15 seconds. When the engine
starts, release the accelerator
pedal gradually as the engine
speeds up and smooths out.
If the engine fails to start in step 3,
push the accelerator pedal to the
floor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 3.
Your vehicle is not designed to tow a
trailer; attempting to do so can void
your warranties.
