Driving in Special Conditions With
Four-Wheel Drive
Four-wheel drive has operating
characteristics that are somewhat
different from front-wheel drive, both on
and off the freeway.
When driving at slow speeds under
high-load conditions, use a low gear when
possible. Low gear operation maximizes
the engine and transmission cooling
capability.
Under severe operating conditions, the air
conditioning may cycle on and off to
prevent the engine from overheating.
Note:
It may be useful to select the most
appropriate drive mode to most effectively
maximize vehicle performance. See Drive
Mode Control (page 223).
Note: It may be useful to switch traction
control off. This allows for more wheel spin
and engine torque in certain conditions or if
your vehicle becomes stuck.
Note: If the front or rear axle is submerged
in water, check the rear axle lubricant and
power transfer unit lubricant and change if
necessary.
See Driving Through Water
Limitations (page 246).
Basic Operating Principles
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
When driving your vehicle on surfaces
made slippery by loose sand, water, gravel,
snow or ice, proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed has been
reduced, ease your vehicle back onto the
road. Do not turn the steering wheel
sharply while returning your vehicle to the
road. It may be safer to stay on the shoulder of
the road and slow down gradually before
returning to the road. You could lose
control if you do not slow down or if you
turn the steering wheel too sharply or
abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control, or roll over. Remember, your
safety and the safety of others is your
primary concern.
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn must be made,
remember to avoid over-driving your
vehicle, for example, turn the steering
wheel only as rapidly and as far as required
to avoid the emergency. Excessive steering
can result in loss of vehicle control. Apply
smooth pressure to the accelerator pedal
or brake pedal when changes in vehicle
speed are required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle rollover, loss
of vehicle control and personal injury. Use
all available road surface to bring your
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 your vehicle goes from one type of
surface to another, for example, from
concrete to gravel, there will be a change
in the way your vehicle responds to a
maneuver, for example, steering,
acceleration or braking.
Note:
For off-road driving,

Trailer Lamps
WARNING: Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
• Do not drive faster than
70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades. •
Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.

Driving In Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Drive through the terrain without varying
vehicle speed. Apply the accelerator and
avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high ambient temperatures, use low
(L) mode, or shift to a lower gear when
possible. Select Low (L) mode or select a
lower gear to maximize the engine and
transmission cooling capability. See
Transmission (page 166).
Use the vehicle's momentum to maintain
forward motion in sand. Avoid coming to
a stop on steep sand slopes as the vehicle
may not be able to continue forward after
it has stopped.
Driving In Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud.
Even four-wheel drive vehicles can lose
traction in slick mud. If your vehicle does
slide, steer in the direction of the slide until
you regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Note: The vehicle brakes are less effective
when wet or muddy.
Driving Over Rocks and Gravel
Gravel is a constantly changing, low-grip
surface. Driving at slow speeds on gravel
reduces the risk of losing traction when you
stop, accelerate or turn a corner.
When approaching large rocks, position
the vehicle so that the tires pass over the
largest obstacle. Note:
Never attempt to straddle a rock that
is large enough to strike your axles or
undercarriage.
Note: Never attempt to drive over a rock
which is large enough to contact the door
sills.
If you lose traction on your wheels facing
uphill, stop and choose a more suitable
route.
Leave a generous gap between your
vehicle and other vehicles to minimize the
risk of damage from flying gravel. Avoid
dust clouds as they reduce visibility.
Before navigating on uneven ground,
secure anything inside the vehicle. If
possible, remove any roof-rack items. Use
the lowest gear possible and approach the
obstacle at a slow speed.
If your vehicle begins to slide down a slope,
steer downhill and gently apply the
throttle. If you lose traction on your uphill
wheels, stop immediately and choose a
more suitable route.
Approach logs, rocky steps or ditches
diagonally. Keep at least three wheels on
the ground at all times.
Climbing A Hill WARNING:
Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
Although natural obstacles can make it
necessary to travel diagonally up or down
a hill or steep incline, try to drive straight
up or straight down.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, first determine
the route you can use.
243
Bronco Sport (CHD) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Driving Hints

Ease off the accelerator as you reach the
other side to diminish the front wave. Apply
the accelerator slowly and as necessary
to climb out of the other side.
Muddy waters can reduce the cooling
system effectiveness by depositing debris
into the radiator.
Extra care must be taken crossing any type
of water. Do not drive into water unless
necessary. You should only drive through
areas that are designated and approved.
High currents even in shallow water can
wash the dirt out from around your tires or
push your vehicle across slippery rocks or
surfaces.
Never attempt to cross flowing water that
is deeper than your vehicles ground
clearance. Even in low currents your
vehicles body surface area can be pushed
downstream and out of control.
Do not cross any body of water that is fast
flowing and rising, wait for the flow rate to
reduce.
Determine exit points that are downstream
of your entry point to allow for drifting.
If there are other vehicles ahead, wait until
they
’ve left the water. Unsettled water can
make a safe passage more challenging.
Know your vehicle ’s abilities and be able
to recover it if something goes wrong.
Keep the doors fully closed during a water
crossing.
Vehicles used to traverse water regularly
should be periodically inspected for signs
of water ingestion in all of the vehicle's
fluids. If water is found inside your vehicle
fluids, service your vehicle or see an
authorized dealer.
After driving through water and as soon as
it is safe to do so, check the brakes, horn,
lights, and steering wheel to make sure
everything is still in working order. Avoid Getting High-Centered
Always keep available ground clearance
in mind and pick a route that minimizes the
risk of catching the underside of the vehicle
on an obstacle and getting high-centered.
Freeing A Stuck Vehicle
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Recovery hooks are mounted to the
vehicle's structure and are used to pull out
the vehicle from a surface or location when
stuck. Recover your vehicle using various
towing apparatus attached to your
recovery hook such as winch, open hook,
or strap.
Note: Do not use recovery hooks to
recreationally tow your vehicle. See Towing
the Vehicle on Four Wheels
(page 240).
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
the accelerator in each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute damage to the transmission
and tires may occur or the engine may
overheat.
If you are unable to free your vehicle call
roadside assistance. See
Roadside
Assistance (page 250).

Bronco Sport (CHD) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Driving Hints

Trail Control allows you to set a speed
between 1 mph (1.6 km/h) to 14 mph
(23 km/h) in a forward motion and 1 mph
(1.6 km/h) to 5 mph (8 km/h) in reverse.
The system controls acceleration and
braking in difficult off-road environments,
which allows you to focus on steering. See
What Is Trail Control
(page 184).
Trail Control Performance:
• Manages wheel slip to maximize
traction.
• Removes the need for you to use both
feet when driving in off-road situations.
• Provides braking to maximize traction
in descents.
• Gives you confidence in difficult
environments.
After Driving Your Vehicle Off-
Road WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death.
Driving off-road places more stress on your
vehicle than most on-road driving. After
driving off-road, check for damage to the
wheels, chassis and underbody.
Inspect the underbody of your vehicle by
checking tires, body structure, steering,
suspension, and exhaust system for
damage.
Inspect the tires for any cuts in the tread
or sidewall area. Also inspect the sidewall
for any bulge indicating damage to the tire.
Make sure that tires are inflated to proper
tire pressure as indicated on the tire
placard. Check the radiator for mud and debris and
clean as needed.
Check that the air filter is clean and dry.
Remove accumulations of plants or brush.
These things could be a fire hazard or hide
damage to the fuel lines, brake hoses, and
propeller shafts.
Make sure that the grille and radiator are
clear of any obstructions that may affect
cooling.
After extended operation in mud, sand,
water, or similar dirty conditions, inspect
the wipers and washers to make sure they
are working.
Note:
Mud caked windows are hard to see
through and can damage wiper blades or
motor.
Check wipers for debris or anything that
may scratch the windshield.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause vibrations
when driving and wheel imbalance.
Remove the material to reduce the
vibration.
Note: If you have removed the impacted
material from the wheels and your vehicle
still has a vibration check your vehicle for
damage or see an authorized dealer.
Inspect the exhaust system for damage or
looseness.
Make sure that the brakes are in proper
working order and free of any mud, stones
and debris, which can become trapped
around the brake rotor, backing plate and
caliper.
Inspect the wheels for dents, cracks, or
other damage.

ENGINE COOLANT CHECK
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 396).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration. Adding Coolant WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury. WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow
this instruction could result in personal
injury. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield.
Note: Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer
fluid reservoir or windshield washer fluid in
the engine coolant reservoir.
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.
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See
Capacities and
Specifications (page 323). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine
or cooling system components and may
not be covered by the vehicle warranty.
277
Bronco Sport (CHD) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Maintenance

Note:
If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Capacities and Specifications (page 323).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
Note: Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be 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 approved to the correct specification. See
Capacities and Specifications (page
323).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your
vehicle checked as soon as possible.
Operating an engine with a low level of
coolant can result in engine overheating
and possible engine damage. In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as
possible.
Water alone, without engine 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.
278
Bronco Sport (CHD) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Maintenance

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:
• You can decrease the coolant
concentration to 40%.
• 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.
Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 323).
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.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING:
Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.
279
Bronco Sport (CHD) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Maintenance

WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage. Engine Coolant Temperature
Management (If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep slope 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 could notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle could enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, slope and ambient
temperature. If this occurs, there is no
need to stop your vehicle. You can
continue to drive.
The air conditioning may 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:
