Mode W reduces torque at the wheels, which helps improve traction when starting off on a slippery surface. Press the button near the base of the gear selector to engage/disengage this driving mode. A "W" will be displayed in the instrument panel when Winter/Wet driving mode is engaged. Mode W will only function if the gear selector is in the Drive ( D) position. Once underway, turn off mode W to improve vehicle performance and fuel economy. Cold starts (turbo engines) When driving before the engine has reached its normal operating temperature, the transmission will shift up at slightly higher engine speeds to heat the three-way catalytic converter as quickly as possible. 137 06 Starting and driving Automatic transmission Kickdown Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly. Kickdown can be used for maximum acceleration or when passing at highway speeds. NOTE The gear selector must be in the D (Drive) position for kickdown to function. 138 06 Starting and driving Shiftlock override Overriding the shiftlock system Shiftlock prevents the gear selector from being moved out of Park unless the ignition key is in position II and the brake pedal is depressed. In certain cases it may be necessary to move the gear selector from the Park position manually.
