COMFORT ADJUSTMENT
2041. Adjust the driver's seat, driver's shoulder belt
anchor,
tilt and telescopic steering and outside rear
view mirrors to the desired position.
2. While pushing the ºSETº button, push button º1º
or º2º until the signal beeps.
The beep sound means that the positions are recorded
in the computer's memory.
By repeating these two steps and pressing the
remaining button, the driving position for another driver
can be recorded.
To set a new memorized position, select the desired
position and perform step 2. The previous memory will
be erased and the new position will be set.
To make only slight changes to an already memorized
position, the easiest way is to first activate the
memorized position, then make the desired changes
and perform step 2 above.

VEHICLE SKID CONTROLSYSTEM
The vehicle skid control system helps to provide
comprehensive control of the systems such as an
anti±lock brake system, traction control, engine
control, electronically modulated air suspension,
etc. This system automatically controls the output
of the brakes or engine to help prevent the vehicle
from skidding when cornering on a slippery road
surface or abrupt steering wheel operation occurs.
