2003 FORD FOCUS cooling

Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system:Illuminates when
the battery is not charging properly.
Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
specificationschapter.
Multi-function: Automatic
transaxle/cooling system (On
SPI, Zetec E or automatic
transaxle vehicles only):
Momentarily illuminates when the
ignition is turned to the ON position and the engine is off. If the light
illuminates while driving, have your vehicle serviced.

Speedometer:Indicates the
current vehicle speed.
Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between“H”and
“C”).If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine and let the engine cool.If it enters
the red section and the multi-function warning light illuminates, refer to

Specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot.

To aid in side window defogging/demisting in cold weather:
1. Select
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer instrument panel vents towards the side windows
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

1.Air flow selections:Controls
the direction of the airflow in the
vehicle. See the following for a brief
description on each control.
:Distributes outside air through
the instrument panel vents.
:Distributes outside air through
the instrument panel vents and the
floor vents.
:Distributes outside air through the floor vents.
:Distributes outside air through the windshield defroster vents and
floor vents.
:Distributes outside air through the windshield defroster vents. The
air conditioner will automatically turn on to dehumidify the air.
2.Fan speed adjustment:Controls the volume of air circulated in the
vehicle.
3.Rear Defrost (if equipped):Refer toRear Defrost.
4.Recirculated air:
Press to toggle between outside air and recirculated
air. Use with A/C for the most fast and efficient cooling of the vehicle. May
help reduce undesirable odors from entering the vehicle. Recirculated air
will not function in
or any position in betweenand

If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transaxle cooling.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transaxle damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.

•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
All Front Wheel Drive (FWD) vehicles:
If your vehicle is equipped with an automatic transaxle, you cannot tow
the vehicle with the front drive wheels on the ground. It is recommended
to tow your vehicle with the drive wheels on a dolly or two wheel car
hauling trailer.
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer or flatbed transport vehicle) your
vehicle can be flat towed (all wheels on the ground) under the following
conditions:
•Place the transmission in N (Neutral).
•Maximum speed is 56 km/h (35 mph).
•Maximum distance is 80 km (50 miles).
If your vehicle is equipped with a manual transaxle, and in the case of a
roadside emergency with a disabled vehicle (without access to wheel
dollies, car hauling trailer or flatbed transport vehicle) your vehicle can
be flat towed (all wheels on the ground) under the following conditions:
•Place the transmission in N (Neutral).
•Maximum distance is unlimited.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Roadside Emergencies

Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.
