or mud. This mode is not for use on dry
pavement.
Note: Four-wheel drive high can turn on or
off automatically based on Drive Mode

surfaces, but does so with additional
gearing for increased torque multiplication.
This mode is only for off-road conditions
such as deep sand, steep slopes, or pulling
heavy objects.
