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,

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