NOTE: The torque converter clutch will not engage

until the transmission fluid and engine coolant are warm

[usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because

the engine speed is higher when the torque converter

clutch is not engaged, it may seem as if the transmission

is not shifting into Overdrive when cold. This is normal.

Manually shifting (using the ERS shift control) between 4

(direct gear) and 5/D (Overdrive gear) positions will

demonstrate that the transmission is able to shift into and

out of Overdrive.

NOTE: If the vehicle has not been driven in several

days, the first few seconds of operation after shifting the

transmission into gear may seem sluggish. This is due to

the fluid partially draining from the torque converter into

the transmission. This condition is normal and will not

cause damage to the transmission. The torque converter

will refill within five seconds of shifting from Park into

any other gear position.

Rocking the Vehicle

If the vehicle becomes stuck in snow, sand, or mud, it can

often be moved by a rocking motion. Move the gear

selector rhythmically between D (Drive) and R (Reverse),

while applying slight pressure to the accelerator.

NOTE: The Electronic Stability Program (ESP) and

Traction Control (if equipped) should be turned OFF

before attempting to rock the vehicle. Refer to “Electronic

Brake Control System” in Section 3 of this manual.

The least amount of accelerator pedal pressure to main-

tain the rocking motion without spinning the wheels or

racing the engine is most effective. Racing the engine or

spinning the wheels, due to the frustration of not freeing

the vehicle, may lead to transmission overheating and

failure. Allow the engine to idle with the transmission

selector in N (Neutral) for at least one minute after every
