three times and unlock the driver’s door when all doors
are closed and there is a keyless access transmitter
inside the interior of the vehicle. When the driver’s
door is reopened, the key in reminder chime will sound

Park Tilt Mirrors
This feature assists the driver by improving rear
obstacle detection and is useful in viewing the curb
when parallel parking.
The passenger and/or driver mirror tilts to a preselected
position when the vehicle is in R (Reverse). This feature
lets the driver view the curb when parallel parking.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used. The mirror then
returns to this new position when the vehicle is shifted
into R (Reverse).
When the vehicle is shifted out of R (Reverse), and a
ve-second delay has occurred, the mirror will return
to its original position. The delay prevents movement
of the mirror if multiple gear transitions R (Reverse)
to D (Drive) to R (Reverse) occur during a parallel
parking maneuver.
If the outside mirror selector switch is in the middle
position, neither outside mirror will move.
Side Blind Zone Alert (SBZA)
If the vehicle has the Side Blind Zone Alert (SBZA)
system, seeSide Blind Zone Alert (SBZA) on page 2-44
for more information.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror’s surface is curved so more can be seen from
the driver’s seat.
Outside Heated Mirrors
For vehicles with this feature:
<(Rear Window Defogger):Press to heat the
mirrors. See “Rear Window Defogger” underDual
Climate Control System on page 3-48for more
information.

it has re-opened, refer to the two options previously
described under the “Close” feature instructions.Do not keep the sunroof open for long periods of time
while the vehicle is not in use. Debris can collect in the
