STARTING AND DRIVING

2003 SC430 from May ’03 Prod. (OM24449U)
(f) Good driving practice
If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope, shift
the selector lever to the ”4” position. Be sure to shift the
selector lever to the ”D” position after climbing the slope.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.
(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see ”If you cannot shift automatic transmission
selector lever” on page 270.
ELECTRONIC THROTTLE
