Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87 or
regular unleaded gasoline blended with a
maximum of 85% ethanol (E85).
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle warranty.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 234).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. Do not use:
•
Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Switching Between E85 and
Gasoline
We do not recommend repeatedly
alternating between E85 and gasoline. If
you switch from using E85 to gasoline, or
from gasoline to E85, add as much fuel as
possible, at least half a tank. Drive your
vehicle immediately for a minimum of 5 mi
(8 km)
to allow it to adapt to the change
in ethanol concentration. If you use E85
exclusively, we recommend that you fill
the fuel tank with regular unleaded
gasoline at each scheduled oil change.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.

If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle
back onto the pavement only after
reducing your speed. Do not turn the
steering wheel too sharply while
returning to the road surface.
• It could be safer to stay on the apron
or shoulder of the road and slow down
gradually before returning to the
pavement. You could lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often could be less risky to strike
small objects, such as highway
reflectors, with minor damage to your
vehicle rather than attempt a sudden
return to the pavement which could
cause the vehicle to slide sideways out
of control or rollover. Remember, your
safety and the safety of others should
be your primary concern.
If Your Vehicle Gets Stuck WARNING: Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander. If your vehicle gets stuck in mud or snow it
could be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability
Control
™, it could be beneficial to
disengage the AdvanceTrac® with Roll
Stability Control ™ system while
attempting to rock the vehicle.
Note: Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the
transmission and tires could occur or the
engine could overheat.
Emergency Maneuvers
• In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid
"over-driving" your vehicle (i.e., turn the
steering wheel only as rapidly and as
far as required to avoid the
emergency). Excessive steering can
result in less vehicle control, not more.
Additionally, smooth variations of the
accelerator and/or brake pedal
pressure should be utilized if changes
in vehicle speed are called for. Avoid
166
2021 Transit (TTH) Canada/United States of America, MK3J 19A321 AA enUSA, Edition date: 202010, Second-Printing All-Wheel Drive

abrupt steering, 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 (i.e., from concrete
to gravel) there is a change in the way
the vehicle responds to a maneuver
(steering, acceleration or braking).
Again, avoid these abrupt inputs.
Sand
Do not continuously drive your AWD
vehicle in deep sand for more than 2.5 mi
(4 km). This can cause the driveline
components to overheat.
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.
Avoid excessive speed because vehicle
momentum can work against you and
cause the vehicle to become stuck to the
point that assistance could be required
from another vehicle. Remember, you
could 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 could
be limited.
Note: Driving through deep water could
damage your vehicle. If the front or rear axle has been
submerged in water, the axle lubricant and
AWD transfer case lubricant should be
checked and changed if necessary.
When driving through water, determine the
depth; avoid water higher than the bottom
of the hubs (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle could stall.
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.
Driving on Hilly or Sloping Terrain
Although natural obstacles could 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.
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.

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 Wheels
(page 308). 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 gearshift lever 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 rapidly
brake 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 system is disabled, normal
braking is still effective. This
lamp momentarily illuminates
when you turn the ignition on. If the lamp
remains on when you release the parking
brake, have the system checked by an
authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does 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.
Note: If the system activates, the brake
pedal could pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
