8-26 Driving tips engine braking effect and prevent overheating of your vehicle's brakes. Do not make sudden downshifts. . When driving uphill in hot weather, the air conditioner may turn off automatically to protect the engine from overheating. . When driving uphill in hot weather, pay attention to the coolant temperature high warning light (for all models) and AT OIL TEMP warning light (for AT and CVT models) because the engine and transmission are relatively prone to overheating under these conditions. If the coolant temperature high warning light and/or the AT OIL TEMP warning light illuminates, immediately turn off the air conditioner and stop the vehicle in the nearest safe location. For further instructions and additional information, refer to the following sections. - "If you park your vehicle in an emergency" F9-2 - "Engine overheating" F9-12 - "Coolant temperature low indicator light/Coolant temperature high warning light" F3-13 - "AT OIL TEMP warning light (AT and CVT models)" F3-15 .
