Uphill/downhill driving

DRIVING UPHILL

The transmission may not upshift to a higher gear if the computer determines the current speed cannot be maintained once a higher gear is engaged.

For smoother vehicle performance, if you release the throttle while climbing a steep grade, the transmission may not upshift. This is normal, as the computer is temporarily preventing shifting. After reaching the top of the hill, normal gear shift function will resume.

DRIVING DOWNHILL

When travelling down steep grades, the computer may automatically select a lower gear. This function assists engine braking efforts, reducing the need for using the brakes.
