Uphill/downhill driving

DRIVING UPHILL

The Twin Clutch SST may not upshift to a higher shift position if the computer determines the current speed cannot be maintained once a higher shift position is engaged.

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

Caution

► Do not use the tendency of the vehicle to creep forward in order to drive at low speeds up hills.
The transmission may be damaged and an accident may occur due to the following conditions.
• The Twin Clutch SST fluid temperature will rise and can cause transmission damage.
• If the vehicle is continuously driven at low speeds using the tendency of the vehicle to creep forward, the vehicle will vibrate or the warning display will appear on the information screen in the multi-information display to alert the driver that the Twin Clutch SST fluid temperature has risen.
After that, if the Twin Clutch SST fluid temperature rises even higher, the transmission protection control will operate.
If this occurs, the vehicle may suddenly reverse as if the gearshift lever was in the “N” (NEUTRAL) position and cause an accident.
If the warning display appears or the transmission protection control operates, refer to “When warning display is showing”.

DRIVING DOWNHILL

When travelling down steep grades, the computer may automatically select a lower shift position.

This function assists engine braking efforts, reducing the need for using the service brakes.
