GENERAL INFORMATION
Note:
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy Wheels
(page 308). See
Warning Lamps and
Indicators (page 102).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidly
by measuring the rate at which you press the
brake pedal. It provides maximum braking
efficiency as long as you press the pedal,
and can reduce stopping distances in critical
situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you turn the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the system
may be disabled. Have the system checked
by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
Note: When the system is operating, the
brake pedal will pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.

The anti-lock braking system will not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
ELECTRIC PARKING BRAKE
The electric parking brake replaces the
conventional handbrake. The operating
switch is located on the instrument panel to
the left of the steering wheel. WARNING
Always set the parking brake and leave
your vehicle with the transmission in
park (P). Note:
When you apply the electric parking
brake in certain conditions, for example on
a steep hill, the electric parking brake may
reapply the brakes within three to ten
minutes. As a result, you may notice various
noises when you apply and release the
electric parking brake. This is normal and no
cause for concern.
Applying the electric parking brake WARNING
If the brake system warning lamp does
not illuminate or flashes, there could
be a problem with your electric parking
brake. Have the system checked by an
authorized dealer as soon as possible. Note:
The brake system warning lamp will
illuminate for ten seconds if you switch the
ignition off after you apply the electric
parking brake, or you apply the electric
parking brake after you switch the ignition
off. Note:
The electric parking brake will not
automatically apply. You must apply the
electric parking brake using the electric
parking brake switch. Pull the switch to apply the electric parking
brake.
The brake system warning lamp will
illuminate to confirm that the electric parking
brake has been applied. See Information
Displays (page 107).

Applying the electric parking brake
when the vehicle is moving
WARNINGS
Applying the electric parking brake
while moving will result in use of the
anti-lock braking system. Do not use the
electric parking brake system when the
vehicle is moving unless the normal brake
system is unable to stop the vehicle. With the exception of emergency
conditions (for example, the brake
pedal does not work or is blocked), do not
apply the electric parking brake while the
vehicle is moving. On bends, or poor road
surfaces or weather conditions, emergency
braking can cause the vehicle to skid out of
control or off the road. If you apply the electric parking brake when
your vehicle is moving, the brake system
warning lamp will illuminate and a warning
tone will sound. See Information Displays
(page 107). If your vehicle speed is above
4 mph
(6 km/h), the braking force is applied as long
as the switch is applied. Release or press the
switch, or press the accelerator pedal to stop
the braking force.
Releasing the electric parking brake Release the electric parking brake either
manually by pressing the bottom of the
switch or automatically.Manual release WARNING
If the brake system warning light
remains illuminated or flashes after you
have released the parking brake, there could
be a problem with your braking system. Have
the system checked by an authorized dealer
as soon as possible. You can manually release the electric parking
brake by:
1. Switching the ignition on.
2. Pressing the brake pedal.
3. Pressing the electric parking brake
switch.
When you release the electric parking brake,
the brake system warning lamp will turn off.
Driving with a Trailer
Depending on the grade and the weight of
the trailer, your vehicle and trailer may roll
backwards slightly when you start on a slope.
185
MKZ (), enUSA BrakesE169086
Page 189 of 516

To prevent this from happening, do the
following:
1.
Pull the switch 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 driver safety belt is fastened.
• The vehicle is accelerated.
• There are no faults detected in the
parking brake system.
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.
The brake system warning lamp will go off
to confirm that you have released the electric
parking brake. 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. To assure
drive away release when starting uphill,
press the accelerator pedal quickly.
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
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking brake and
put the transmission in park (P). WARNINGS
You must remain in your vehicle once
you have activated the system.
During all times, you are responsible
for controlling your vehicle, supervising
the system and intervening, if required. If the engine is revved excessively, or
if a malfunction is detected, the system
will be deactivated. 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 will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your foot
from the brake to the accelerator pedal. The
brakes are released 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).
186
MKZ (), enUSA Brakes
Page 190 of 516
The system will activate automatically on any
slope that will cause significant vehicle
rollback.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep the
brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain on
the slope without rolling away for about
two or three seconds. 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 release automatically.

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
In certain situations for example, stuck in
snow or mud, turning the traction control off
may be beneficial as this allows the wheels
to spin with full engine power. Depending
on the type of system you have on your
vehicle, you can either turn the system off
using the information display or by pressing
the button.
Switching the System Off Using the
Information Display Controls (If Equipped)
Your vehicle comes with this feature already
enabled. If required, you can switch this
feature off using the information display
controls.
See General Information (page
107).
Switching the System Off Using a
Switch
(If Equipped)
The button is located in the instrument panel.
Press the button. You will see a message in
conjunction with an illuminated icon in the
display. Press the button again to return the
system to normal mode.
When you switch the traction control system
off, stability control remains fully active. System Indicator Lights and Messages WARNING
If a failure has been detected within
the AdvanceTrac system, the stability
control light will illuminate steadily. Verify
that the AdvanceTrac system was not
manually disabled through the information
display. If the stability control light still
illuminates steadily, have the system serviced
by an authorized dealer immediately.
Operating your vehicle with AdvanceTrac
disabled could lead to an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death. The stability control light
temporarily illuminates on engine
start-up and flashes when a driving
condition activates the stability system. The stability control off light
temporarily illuminates on engine
start-up and stays on when you
turn the traction control system off.
