Your car is going to run into trouble at some point no matter how reliable it's been thus far. Depending on the situation, you might need to fix a flat tire quick or be prepared to wait overnight on a backcountry road until you can get help. While you can't always prevent these issues, you can prepare for them in advance.
INFINITI dealerships recommend that all drivers have a stockpile of supplies inside the trunk or in the backseat to get through emergencies like these safely. Check this list and make sure you have everything you need!
Your top priority for emergency supplies is a first aid kit. Kits should contain all the basics for cleaning, disinfecting, and treating wounds. Include a small selection of OTC pain relievers (like Tylenol and ibuprofen), allergy medications like Benadryl, and any other medications used on a regular basis.
Snacks and MREs
There's no telling where you'll be stranded, or when, so keeping a few snacks or even an MRE (Meal Ready-to-Eat) on hand is wise. Stock up on non-perishables like granola bars, energy bars, dried foods, and camping style ready-to-eat meals; keep them in a plastic tote in the trunk. Include utensils and a few drinks. These will be invaluable if you get stuck on the highway in a natural disaster or even gridlocked traffic.
Never forget water. It's the necessity for life, and you'll function far more efficiently if you're not dehydrated. Individual water bottles work fine, but you may want a couple of large jugs instead. Your car may overheat or need more radiator fluid, and water will do the trick until you can get back to civilization.
Clothes and Blankets
Don't get caught off guard by the elements. Keep a few sets of clothes in your vehicle and at least two pairs of warm socks. Also, leave a jacket or two in your trunk for when it gets cold. Blankets (including space blankets) serve many purposes and could save you from hypothermia in a snowstorm.
Having the proper hand wear around for situations such as tire changes and motor problems will more than pay for itself. Make sure you leave at least one pair of heavy-duty gloves in your trunk for mechanic work or other heavy-duty tasks.
Spare Tire and Tire Kit
Pretty much everyone gets a flat tire at some point, especially if you spend a significant amount of time driving. Most vehicles come with a "five-mile" spare tire, but you may want to invest in a proper spare. You should also have tire removal tools on hand, as well as a flat tire kit. Better to try patching it up before replacing it altogether! Last, if you don't have one already, pick up a tire kit with a battery powered air pump for re-inflating tires.
Surprisingly, few drivers think to keep a set of jumper cables in the trunk. Not only will these be a life-saver for your dead battery, but you'll quickly make friends by being one of the few people at work with a set on you.
Last, but not least, is the trusty flashlight. Smartphones have flashlight apps, but they're not as powerful, convenient to handle, or as long-lasting as standard full-size flashlights. Heavy-duty MAG lights and mechanic flashlights are preferred. Just be sure to stick an extra set of batteries in the dash.
It's good practice to keep a miniature survival kit in your vehicle at all times. Although the chances of being stuck for more than a few hours are slim, longer stretches aren't outside the realm of possibility. It doesn't hurt to drive a reliable vehicle, either, and that's a goal INFINITI of Thousand Oaks can help with!
