8-2 Driving tips/New vehicle break-in driving – the first 1,000 miles (1,600 km) New vehicle break-in driving – the first 1,000 miles (1,600 km) S08AA The performance and long life of your vehicle are dependent on how you handle and care for your vehicle while it is new. Follow these instructions during the first 1,000 miles (1,600 km): . Do not race the engine. And do not allow engine speed to exceed 4,000 rpm except in an emergency. . Do not drive at one constant engine or vehicle speed, either fast or slow. . Avoid starting suddenly and rapid ac- celeration, except in an emergency. . Avoid hard braking, except in an emer- gency. The same break-in procedures should be applied to an overhauled engine, newly mounted engine or when brake pads or brake linings are replaced with new ones. Fuel economy hints S08AB The following suggestions will help to save fuel. . Select the proper gear position for the speed and road conditions. . Avoid sudden acceleration or decelera- tion. Always accelerate gently until you reach the desired speed. Then try to maintain that speed for as long as possi- ble. . Do not pump the accelerator and avoid racing the engine. . Avoid unnecessary engine idling. . Keep the engine properly tuned. . Keep the tires inflated to the correct pressure shown on the tire placard, which is located under the door latch on the driver’s side. Low pressure will increase tire wear and fuel consumption. . Use the air conditioner only when necessary. . Keep the front and rear wheels in proper alignment. . Avoid carrying unnecessary luggage or cargo. Engine exhaust gas (carbon monoxide) S08AC WARNING . Never inhale engine exhaust gas. Engine exhaust gas contains carbon monoxide, a colorless and odorless gas which is dan- gerous, or even lethal, if inhaled. . Always properly maintain the en- gine exhaust system to prevent engine exhaust gas from entering the vehicle. . Never run the engine in a closed space, such as a garage, except for the brief time needed to drive the vehicle in or out of it. . Avoid remaining in a parked ve- hicle for a lengthy time while the engine is running. If that is un- avoidable, then use the ventila- tion fan to force fresh air into the vehicle. . Always keep the front ventilator inlet grille free from snow, leaves or other obstructions to ensure that the ventilation system al- ways works properly.
