BEFORE YOU DRIVE
MIRRORS
Exterior Mirror Fold
1. Switch the ignition on.
2. To fold the mirrors, rotate the
control switch to the mirror fold
icon.
3. To unfold the mirrors rotate the control
switch away from the mirror fold icon.
NOTE: If the switch remains in the mirror
fold position the mirrors will stay folded
until the switch is moved.
Exterior Mirror Automatic Fold
The exterior mirrors can be set so that they
fold automatically when the vehicle is locked.
Unfolding occurs as a door is opened, not
when the vehicle is unlocked. See Auto Fold
Mirrors, page 3.12.
Mirror Dipping in Reverse
The exterior mirrors can be set to dip when
reverse is engaged. This provides a view of the
ground to the rear of the vehicle. See Reverse
Mirror Dip, page 3.13.

Exterior mirrors are heated when the demist
button in pressed (see Demisting/Defrosting,

heating also happens automatically when the
ambient temperature goes below 5°C (41°F)
and the engine is running.
