Warning! G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
i
When you brake or stop, the transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.
