The steering wheel can be moved in 
any of four directions. Adjust by moving 
the control lever in the desired direc-
tion.
Do not adjust the steering wheel 
while the vehicle is moving. There 
is a risk of accident from unexpected 
movement.< 
To store the steering wheel setting, 
refer to "Seat, mirror and steering 
wheel memory" on page 54.390de711
Automatic steering wheel 
adjustmentIn order to make it easier to get into and 
out of the vehicle, the steering wheel 
automatically moves into the top posi-
tion and returns to the driving (memory) 
position.
This automatic feature is controlled by 
the position of the ignition key and by 
the driver's door.
The heated steering wheel feature is 
available for operation when the ignition 
key is in position 2. 
Press the button to switch on and off.
The lamp within the button lights up 
when the steering wheel heater is in 
operation.
If you have a multifunction steering 
wheel without steering wheel heating, 
the button for the recirculated-air mode 
is in this location (refer to page 22).
