The system makes it easier to pull away
when the vehicle is on a slope without the
need to use the parking brake.
When the system is active, the vehicle will
remain stationary on the slope for a short
time after you release the brake pedal.
During this time, you have time to move
your foot from the brake to the accelerator
pedal and pull away. The brakes are
released automatically once the engine
has developed sufficient drive to prevent
the vehicle from rolling down the slope.
This is an advantage when pulling away
on a slope, for example from a car park
ramp, traffic lights or when reversing uphill
into a parking space.
WARNING
The system does not replace the
parking brake. When you leave the
vehicle, always apply the parking
brake and select first or reverse gear. USING HILL START ASSIST
The system is activated automatically
when you stop your vehicle on a slope
greater than 3%. The system operates with
the vehicle facing downhill if reverse gear
is selected and with the vehicle facing
uphill if any forward gear is selected.
Vehicles with manual
transmission only
The system can be switched on and off
using the information display. See General
Information (page 83).
Activating the system
WARNINGS
You must remain in the vehicle once
you have activated the system. WARNINGS
At all times you are responsible for
controlling the vehicle, supervising
the system and intervening, if
required. If a malfunction is detected when the
system is active, the system will be
deactivated and a message will be
shown in the display. See Information
Messages (page 90). You can activate the system only if the
following conditions have been met:
•
The engine is running.
• The system is switched on.
• On vehicles with manual transmission,
the clutch pedal is pressed.
• No failure mode is present.
To activate the system:
1. Press the brake pedal to bring the vehicle to a complete standstill. Keep
the brake pedal depressed.
2. If the sensors detect that the vehicle is
on a slope the system will be activated
automatically.
3. When you remove your foot from the brake pedal, the vehicle will remain on
the slope without rolling away for a
short time. This hold time will
automatically be extended if you are
in the process of driving off.
4. Drive off in the normal manner. The brakes will be released automatically.
Deactivating the system
To deactivate the system, perform one of

WARNINGS
The system does not relieve you of
your responsibility to drive with due
care and attention.
At all times you are responsible for
controlling the vehicle, supervising
the system and intervening if
required. You must observe that the selected
space remains clear of obstructions
at all times in the manoeuver.
Vehicles with overhanging loads,
street furniture and other items may
not be detected by the system. You
must make sure that the selected space
is suitable for parking. Do not use the system if a trailer is
attached to the vehicle.
Do not use the system if a bike rack
is attached to the back of the vehicle.
Do not use the system if an
overhanging item is attached to the
roof.
If the manoeuvre is interrupted
before completion, the system will
be disabled. The steering wheel
position will not indicate the true position
of the steering and you will have to take
control of the vehicle. Make sure that loose clothing, your
hands or your arms do not get caught
in the rotating steering wheel. The system will detect a suitable parallel
parking space and steer the vehicle into
the space. The system controls the
steering while the driver controls the
accelerator, transmission and brakes. The
manoeuvre can be stopped at any time by
holding the steering wheel or pressing the
active park assist switch. See At a Glance
(page 10).
The system will visually and audibly
instruct the driver throughout the
procedure to safely park the vehicle.
USING ACTIVE PARK ASSIST
CAUTIONS
The sensors may not detect objects
in heavy rain or other conditions that
cause disruptive reflections.
The sensors may not detect objects
with surfaces that absorb ultrasonic
waves.
The sensors may not detect the kerb.
Note:
If the traction control system is
disabled active park assist will not be
available. See General Information (page
83).
The system will not align the vehicle
correctly if:
• a spare tyre, or a tyre worn significantly
more than the other tyres is used
• the factory installed tyre size is not
used on the vehicle
• the tyres skid
• you allow the vehicle to roll
• the weather conditions are poor (heavy
rain, snow, fog, etc).
