To prevent this from happening, do the
following:
1. Pull the switch up and hold it in this
position.
2. Drive your vehicle, then release the
switch when you notice that the engine
has developed sufficient driving force.
Automatic Release - Drive Away
Release
Your vehicle will automatically release the
parking brake if:
• The driver door is closed.
• The transmission is in a forward or
reverse gear.
• The vehicle is accelerated.
• There are no faults detected in the
parking brake system.
The brake system warning lamp will go off
to confirm that you have released the
electric parking brake.
Note: If the electric parking brake warning
lamp stays illuminated, the electric parking
brake will not automatically release. You
must release the electric parking brake using
the electric parking brake switch.
Note: The electric parking brake drive away
release makes starting on a hill easier. This
feature will release the parking brake
automatically when the vehicle has
sufficient drive force to move up the hill.

Battery With No Charge

WARNING
You will not be able to apply or
release the electric parking brake if
the battery is low or has no charge.
If the battery is low or has no charge, use
jumper cables and a booster battery.

HILL START ASSIST

The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake. Failure to leave your vehicle securely
parked may lead to a crash or injury. See
Electric Parking Brake (page 193).
You must remain in your vehicle
when the system turns on. At all
times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required. Failure
to take care may result in the loss of
control of your vehicle, serious personal
injury or death.
The system will turn off if a
malfunction is apparent or if you rev
the engine excessively. Failure to
take care may result in the loss of control
of your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has
developed sufficient drive to prevent your
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.
Note: The system only functions when you
bring your vehicle to a complete standstill.
Shift the gearshift lever to reverse (R) when
facing downhill and first gear (1) when
facing uphill.
