Operating AWD Vehicles With Spare
or Mismatched Tires
WARNING
Only use replacement tires and wheels
that are the same size, load index,
speed rating and type (such as P-metric
versus LT-metric or all-season versus
all-terrain) as those originally provided by
Ford. The recommended tire and wheel size
may be found on either the Safety
Compliance Certification Label (affixed to
either the door hinge pillar, door-latch post,
or the door edge that meets the door-latch
post, next to the driver’ s seating position), or
the Tire Label which is located on the B-Pillar
or edge of the driver’ s door. If this
information is not found on these labels, then
you should contact your authorized dealer
as soon as possible. Use of any tire or wheel
not recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of loss
of vehicle control, vehicle rollover, personal
injury and death. A spare tire of a different size other than the
tire provided should never be used. The
AWD system may disable automatically and
enter front-wheel drive only mode to protect
driveline components if a non-full sized tire
is installed. This condition may display an
AWD OFF message in the information
display. If there is an AWD OFF message in
the information display from using a non-full
sized spare tire, this indicator should turn off
after reinstalling the repaired or replaced
normal road tire and cycling the ignition off
and on. It is recommended to reinstall the
repaired or replaced road tire as soon as
possible.
Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch high
profile tires on the rear axle) could cause the
AWD system to stop functioning and default
to front-wheel drive or damage the AWD
system. However, the AWD system is
capable of tolerating any combination of new
and worn tires of the same original tire size.
For example, using 3 worn tread tires and 1
new tread tire all of the same original tire
size, can be tolerated by the AWD system. Driving In Special Conditions With All-
Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
181
MKZ (CC9) Canada/United States of America, enUSA, First Printing All-Wheel Drive
(If Equipped)

acceleration or braking which could result
in an increased risk of loss of vehicle
control, vehicle rollover and/or personal
injury. Use all available road surface to
return the vehicle to a safe direction of
travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (that is, from concrete
to gravel) there will be a change in the
way the vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
Most of the time traction control improves
tire traction by managing wheel slip through
Brake, Engine, and AWD calibrations.
However, during low speed driving, disabling
traction control in deep sand can help keep
the wheels moving to maintain vehicle
momentum. When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels.
Do not drive your vehicle in deep sand for
an extended period of time. This could cause
the AWD system to overheat and default to
front-wheel drive. If this occurs, an AWD OFF
message displays in the information display.
To resume normal AWD function as soon as
possible, stop the vehicle in a safe location
and stop the engine for at least 10 minutes.
After the engine has been restarted and the
AWD system has adequately cooled, the
AWD OFF message turns off and normal
AWD function returns. In the event the
engine is not stopped, the
AWD OFF
message turns off when the system cools
and normal AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L (Low)
gear when possible. L (Low) gear operation
will maximize the engine and transmission
cooling capability. Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Avoid excessive speed because vehicle
momentum can work against you and cause
the vehicle to become stuck to the point that
assistance may be required from another
vehicle. Remember, you may be able to back
out the way you came if you proceed with
caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom of
the hubs (for trucks) (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.
183
MKZ (CC9) Canada/United States of America, enUSA, First Printing All-Wheel Drive
(If Equipped)

Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does
slide, steer in the direction of the slide until
you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.
Note:
Driving through deep water may
damage the transmission.
If the front or rear axle is submerged in water,
have the power transfer unit (PTU) or rear
axle serviced by an authorized dealer. Driving on Hilly or Sloping Terrain
Note:
Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will use.
Do not drive over the crest of a hill without
seeing what conditions are on the other side.
Do not drive in reverse over a hill without
the aid of an observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If you do stall out, do not try to turnaround
because you might roll over. It is better to
back down to a safe location. Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral; instead, disengage
overdrive or manually shift to a lower gear.
When descending a steep hill, avoid sudden
hard braking as you could lose control. The
front wheels have to be turning in order to
steer the vehicle.
184
MKZ (CC9) Canada/United States of America, enUSA, First Printing All-Wheel Drive (If Equipped)E143949

Note:
If the engine speed drops too low, the
information display indicates low engine
speed. Shift to a lower gear (manual
transmission only) to avoid automatic
cancellation.
Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open the
door while stopped.
• Holding the vehicle at a stop
continuously for more than two minutes.
Hilly Condition Usage
Note: An audible alarm sounds and the
system shuts down if it is applying brakes
for an extended period of time. This allows
the brakes to cool. The system functions
normally again when the brakes cool. Select a lower gear during prolonged
downhill driving on steep slopes, such as
mountainous areas, when the system is
active. In such situations, the system needs
additional engine braking to reduce the load
on the vehicle
’s regular brake system to
prevent the brakes from overheating.
Switching Adaptive Cruise Control Off
Press and release OFF when the system is
in stand by mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off.
Detection Issues WARNING
On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges, tunnels
and safety barriers. In these cases, the
system may brake late or unexpectedly. At
all times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. The radar sensor has a limited field of vision.
It may not detect vehicles at all or detect a
vehicle later than expected in some
situations. The lead vehicle graphic does not
illuminate if the system does not detect a
vehicle in front of you.
221
MKZ (CC9) Canada/United States of America, enUSA, First Printing Cruise Control

If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment. Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.
PRE-COLLISION ASSIST WARNINGS
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. WARNINGS
The system does not detect cyclists,
animals, pedestrians at night or
vehicles that are driving in a different
direction. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. The system does not operate during
hard acceleration or steering. Failure
to take care may lead to a crash or personal
injury. The system may fail or operate with
reduced function during cold and
severe weather conditions. Snow, ice, rain,
spray and fog can adversely affect the
system. Keep the front camera and radar free
of snow and ice. Failure to take care may
result in the loss of control of your vehicle,
serious personal injury or death. In situations where the vehicle camera
has limited detection capability, this
may reduce system performance. These
situations include but are not limited to direct
or low sunlight, vehicles at night without tail
lights, unconventional vehicle types,

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We recommend,
Robinair® Coolant and Battery Refractometer
75240 (Rotunda tool part number:
ROB75240). We do not recommend the use
of hydrometers or coolant test strips for
measuring coolant concentration.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Adding Coolant WARNING
Never remove the coolant reservoir
cap while the engine is running or hot. It is very important to use prediluted coolant
meeting the correct specification in order to
avoid plugging the small passageways in the
engine cooling system. See Capacities and
Specifications (page 374). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant meeting the correct specification. See Capacities and
Specifications
(page 367).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. Note:
During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Do not mix different colors or types of
prediluted coolant in your vehicle. Mixing of
prediluted coolant or using an incorrect
prediluted coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
In case of emergency, you can add a large
amount of water without prediluted coolant
in order to reach a vehicle service location.
On arrival do the following:
1. Drain the cooling system.
2. Chemically clean the cooling system. We
recommend Motorcraft Premium Cooling
System Flush.
3. Refill with prediluted coolant as soon as possible.
304
MKZ (CC9) Canada/United States of America, enUSA, First Printing Maintenance

Water alone, without prediluted coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available. Dispose of used engine coolant in an
appropriate manner. Follow your
community’
s regulations and standards for
recycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection. Coolant
concentrations below 40% decrease the
freeze and corrosion protection
characteristics of the coolant and may
cause engine damage. Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolant
temperature gauge moves toward the red
zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
305
MKZ (CC9) Canada/United States of America, enUSA, First Printing Maintenance

If you tow a trailer with your vehicle, the
engine may temporarily reach higher a
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road. You can
continue to drive your vehicle.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature does
not drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue. AUTOMATIC TRANSMISSION
FLUID CHECK
6F35/HF35 transmission
(If Equipped)
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
working properly, (For example: if the
transmission slips or shifts slowly) or if you
notice some sign of fluid leakage.
See
Scheduled Maintenance (page 495).
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
