If you are uncomfortable with the proximity
to any vehicle or object, you may choose
to override the system by grabbing the
steering wheel or by pressing the Active
Park Assist button.
The system may not correctly operate in
any of the following conditions:
• You use a spare tire or a tire
significantly worn more than the other
tires.
• One or more tires are improperly
inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space. For
example, a pedestrian or cyclist.
• The edge of the neighboring parked
vehicle is high off the ground. For
example, a bus, tow truck or flatbed
truck.
• The weather conditions are poor. For
example, during heavy rain, snow or
fog.
Note: Keep the sensors on the bumper or
fascia free from snow, ice and large
accumulations of dirt. Covered sensors can
affect the system's accuracy. Do not clean
the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference. For
example, motorcycle exhaust, truck air
brakes or horns.

Parking Aids
Note: Following a change in tire size, the
system must recalibrate and operation may
be impaired for a short time.
Do not use the system if:
• You have attached a foreign object
close to the sensors on the front or rear
of your vehicle. For example, a bike rack
or trailer.
• You attach an overhanging object to
the roof. For example, a surfboard.
• A foreign object damages or obstructs
the front or rear bumper or side
sensors.
• The correct tire size is not in use on your
vehicle. For example, a mini-spare tire.
Using Active Park Assist - Parallel
Parking
E146186
When driving at a speed less than 22 mph
(35 km/h), the system automatically scans
both sides of your vehicle for an available
parking space. The system displays a
message and a corresponding graphic to
indicate it is searching for a parking space.
Use the direction indicator to select
searching either to the left-hand side or
right-hand side of your vehicle.
Note: If the direction indicators are not
used, the system defaults to the passenger
side of your vehicle.
