Driving and Operating Notice: Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. D4 (Automatic Overdrive): This position is for normal driving. When operating the vehicle in severe cold conditions, the transmission may be prevented from shifting into D4 gear until the transmission fluid has warmed up to its operational temperature. Notice: If the vehicle seems to start up rather slowly or not shift gears when you go faster, and you continue to drive the vehicle that way, you could damage the transmission. Have the vehicle serviced right away. You can drive in 2 (Second) when you are driving less than 55 km/h (35 mph) and D4 (Automatic Overdrive) for higher speeds until then. 2 (Second): This position gives you more power but lower fuel economy. You can use 2 (Second) on hills. It can help control vehicle speed as you go down steep mountain roads, while using the brakes off and on. Notice: Do not drive in 2 (Second) at speeds over 105 km/h (65 mph), or you can damage the transmission. Use D4 (Automatic Overdrive) as much as possible. Do not shift into 2 (Second) unless you are going slower than 105 km/h (65 mph) or you can damage the engine. 1 (First): This position gives you even more power but lower fuel economy than 2 (Second). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in 1 (First), the transmission will not shift into first gear until the vehicle is going slowly enough. 9-27 Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. If there is a malfunction with the automatic transmission, the malfunction indicator lamp or the HOLD indicator light will turn on or flash. See Malfunction Indicator Lamp on page 5‑14. Have the vehicle fixed as soon as possible.
