Screen Wash - should be mixed at the correct ratio to stop it freezing in the car and nozzles.
Engine Coolant - (Antifreeze) again should be mixed to the correct ratio. If too weak or too strong it can impair the performance.
Engine Oil - Make sure you have the correct engine oil as specified by the manufacturer. This will reduce undue wear on the engine during cold starting.
Battery - Make sure the battery is fully charged (and is holding it’s charge). Cold temperatures put greater demand on the battery.
Ice Scrapper - Allows you to manually clear the ice/snow.
De-Icer - Helps clear the ice/snow quicker. Failure to remove snow and ice properly could incur a fine and add 3 points to your licence.
Torch & Spare Batteries - If you break down, you'll need to find a safe place to wait for roadside assistance. A torch will help light your way on a dark verge.
Mobile Phone - Make sure your phone is fully charged, or carry a portable charger in case of breakdown. If you're delayed because of bad weather (or in a weather related incident), it's a good idea to let your loved ones know. It'll save them worrying and stop any distracting texts and phone calls coming in while you're behind the wheel.
