1. Make sure that your vehicle is at a complete stop before you shift into
R (Reverse). Failure to do so may damage the transmission.
2. Move the gearshift lever into the neutral position and wait at least
three seconds before shifting into R (Reverse).
• The gearshift lever can only be moved into R (Reverse) by moving it
from left of 3 (Third) and 4 (Fourth) before shifting into R (Reverse).
This is a lockout feature that protects the transmission from
accidentally being shifted into R (Reverse) from
