STARTING AND DRIVING
206
In the power mode, the ”ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the normal
mode.
To return to the normal mode, push the driving pattern selector
switch lightly on the ”SNOW” side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
”SNOW” side, the snow mode is turned on and the ”ECT
SNOW” light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern selector
switch on the ”SNOW” side again.
When you turn the ignition switch off in the snow mode, the
mode automatically changes to the normal mode.
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 40 km/h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a great
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION
To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow–covered) or winding roads.
Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
