If you don't have booster cables in your trunk, you should have, especially for winter driving. Even newer engines can mysteriously conk out when you least expect it. Canadian tire has a wide assortment of booster cables, ranging in price from $10.49 for 8-ft cables to $139.99 for 20-ft cables. I'd probably choose something in the middling price range of $31.99 for 16-ft cables in a compact carry case.
