Instruments and controls the ambient temperature and driving conditions. We recommend that you drive moderately until the pointer of the temperature gauge reaches near the middle of the range. Engine operation is optimum with the engine coolant at this temperature range and high revving operation when the engine is not warmed up enough should be avoided. ! Ambient temperature gauge A B If the pointer exceeds the normal operating range, safely stop the vehicle as soon as possible. See the "In case of emergency" in chapter 9. A) U.S. spec. models B) Canada spec. models UG3028AB The ambient temperature gauge shows the ambient temperature in a range from −22°F to 122°F (−30°C to 50°C). The gauge can give a false reading under any of the following conditions: " When there is too much sun. " During idling; while running at low speeds in a traffic jam; when the engine is restarted immediately following a shutdown. - CONTINUED - 3-11
