STARTING AND DRIVING
394
CAUTION
When starting in cold weather, the auto-matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it has reachedthe proper operating temperature.
The engine should be idling when thegear selector is moved. Never accelerateuntil the gear is fully engaged. Accelerat-ing rapidly before a gear is properlyengaged could lead to harder wear ofcomponents.
To help prevent the transmission oil fromoverheating, select P or N when idling ata standstill for prolonged periods of time.

Refilling coolant
Coolant helps keep the combustion engine atthe right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions onthe package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant.
If there is coolant under the vehicle, smoke fromthe cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrewthe cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
