2021 FORD GT heating

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, slope 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
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 279).
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, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
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.
BRAKE FLUID CHECK WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death.

General Information
WARNING: Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
Note: Do not use the kit if you have severely
damaged a tire. Only seal punctures located
within the tire tread with the kit.
Do not attempt to repair punctures larger
than
0.2362 in (6 mm) or damage to the
tire's sidewall. The tire may not completely
seal.
Loss of air pressure may adversely affect
tire performance. For this reason:
Note: Do not drive the vehicle above
50 mph (80 km/h)
.
Note: Do not drive further than
120 mi
(200 km). Drive only to the closest
authorized Ford dealer or tire repair shop to
have your tire inspected.
• Drive carefully and avoid abrupt
steering maneuvers.
• Periodically monitor tire inflation
pressure in the affected tire; if the tire
is losing pressure, have the vehicle
towed on a flat bed.
• Read the information in the Tips for
Use of the Kit section to make sure safe
operation of the kit and your vehicle.
Tips for Use of the Kit
To ensure safe operation of the kit:
• Read all instructions and cautions fully.
• Before operating the kit, make sure
your vehicle is safely off the road and
away from moving traffic. Switch on
the hazard lights.
• Always set the parking brake to ensure
the vehicle does not move
unexpectedly. •
Do not remove any foreign objects,
such as nails or screws, from the tire.
• When using the kit, leave the engine
running (only if the vehicle is outdoors
or in a well-ventilated area) so the
compressor does not drain the
vehicle's battery.
• Do not allow the compressor to
operate continuously for more than 15
minutes. This will help prevent the
compressor from overheating.
• Never leave the kit unattended during
operation.
• Sealant compound contains latex.
Those with latex sensitivities should
use appropriate precautions to avoid
an allergic reaction.
• Keep the kit away from children.
• Only use the kit when the ambient
temperature is between -22°F (-30°C)
and 158°F (70°C).
• Only use the sealing compound before
the use-by date. The use-by date is on
a label on the sealant canister, which
you can see through the rectangular
viewing window on the bottom of the
compressor. Check the use-by date
regularly and replace the canister after
four years of non-use.
• Do not store the kit unsecured inside
the passenger compartment of the
vehicle as it may cause injury during a
sudden stop or crash. Always store the
kit in its original location.
• After sealant use, an authorized Ford
dealer must replace the tire pressure
monitoring system sensor and valve
stem on the wheel.
• Operating the kit could cause an
electrical disturbance in radio
operation.

Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension (if
equipped) may require alignment
of all four wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
USING SUMMER TIRES
Your Ford GT was built with Michelin Pilot
Sport Cup 2 tires which are a summer tire.
Summer tires provide superior
performance on wet and dry roads.
Summer tires do not have the Mud and
Snow (M+S or M/S) tire traction rating on
the tire side wall. Since summer tires do
not have the same traction performance
as All-season or Snow tires, we do not
recommend using summer tires when
temperatures drop to about 45°F (7°C) or
below (depending on tire wear and
environmental conditions) or in snow and
ice conditions. Like any tire, summer tire
performance is affected by tire wear and
environmental conditions. If you must drive
in those conditions, we recommend using
Mud and Snow (M+S, M/S), All-season or
Snow tires.
Always store your summer tires indoors at
temperatures above 19°F (-7°C). The
rubber compounds used in these tires lose
flexibility and may develop surface cracks
in the tread area at temperatures below
19°F (-7°C)
. If the tires have been
subjected to 19°F (-7°C) or less, warm
them in a heated space to at least 41°F
(5°C) for at least 24 hours before installing
them on a vehicle, or moving the vehicle with the tires installed, or checking tire
inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply
heat or blow heated air directly on the tires.
Always inspect the tires after storage
periods and before use.
USING SNOW CHAINS
WARNING: If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load
range as the original tires listed on the
tire placard, and they must be installed
on all four wheels. Mixing tires of
different size or construction on your
vehicle can adversely affect your
vehicle's handling and braking, and may
lead to loss of vehicle control. WARNING:
Do not use snow chains
or cables on this vehicle as they may
cause damage to your vehicle which may
lead to loss of vehicle control.
Snow chains have not been approved for
use on your vehicle.
TIRE PRESSURE MONITORING
SYSTEM WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.

Oils and Fluids
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair.
NORMAL SCHEDULED MAINTENANCE
