DRIVING TIPS CAUTION D Do not exceed 72 km/h (45 mph) or the posted towing speed limit, whichever is lower. Because instability (swaying) of a towing vehicle−trailer combination usually increases as the speed increases, exceeding 72 km/h (45 mph) may cause loss of control. D Slow down and downshift before descending steep or long downhill grades. Do not make sudden downshifts. D Avoid holding the brake pedal down too long or too frequently. This could cause the brakes to overheat and result in reduced braking efficiency. HOW TO SAVE FUEL AND MAKE YOUR VEHICLE LAST LONGER Improving fuel economy is easy - just take it easy. It will help make your vehicle last longer, too. Here are some specific tips on how to save money on both fuel and repairs: D Keep your tires inflated at the correct pressure. Check the pressure every two weeks, or at least once a month. Underinflation causes tire wear and wastes fuel. D Do not carry unnecessary weight in your vehicle. Excess weight puts a heavier load on the hybrid system, causing greater fuel consumption. D Accelerate slowly and smoothly. Avoid jackrabbit starts. D Avoid continuous changes of speed. driving wastes electric power and fuel. Stop−and−go D Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper distance from other vehicles to avoid sudden braking. This will also reduce wear on your brakes. D When parking, be sure to put the transmission into the "P" position. In the "N" position, the gasoline engine operates but electricity cannot be generated. The traction battery will be discharged requiring unnecessary engine power to recharge. 473
