SRS AIRBAGS
The SRS (Supplemental Restraint System) airbags are
designed to provide further protection for the driver and
front passenger when added to the primary protection
provided by the seat belts.
In response to a severe frontal impact, the SRS airbags
work together with the seat belts to help prevent or r educe
injury by inflating, in order to decrease the likelihood of
the driver's or front passenger's head or chest directly
hitting the steering wheel or dashboard.
The passenger airbag is activated even with no passenger in
the front seat.
Be sure to wear
your seat belt.

STARTING AND DRIVING
242In the power mode, the ºECT PWRº 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 ºSNOWº 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
ºSNOWº side, the snow mode is turned on and the ºECT
SNOWº light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern
selector switch on the ºSNOWº 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.

IN CASE OF AN EMERGENCY
