Clear away ice and snow that has accumulated under the fenders to avoid making steering difficult. During severe winter driving, stop when and where it is safe to do so and check under the fenders periodically. n During cold weather below -4°F (-20°C) If the engine is difficult to start using the normal method (without depressing the accelerator pedal), turn the ignition switch to the "START" position while slightly depressing the accelerator pedal. n Parking in cold weather WARNING Snow can trap dangerous exhaust gases under your vehicle.
