The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate control
system, and rear defogger in order to reduce battery drain.If you live in a region where winter is extremely cold,
an engine block heater will improve starting and

below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.

smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
