Top up your power steering fluid to ensure a smooth ride. Contaminated power steering fluid is a common cause of a stiff steering wheel, as are low levels of fluid. Fix contaminated fluid with a system flush. If the fluid level is low, there may be a leak in the system. Keep the reservoir filled with fresh fluid.
Although you can take have the battery tested by a mechanic, you can check for obvious signs of corrosion on the terminals or for signs of cracks or leaks. Have the battery fixed or replaced immediately if you find anything wrong.^{[10]

Why do vehicles need to be checked before they are driven?
