brake FORD MUSTANG 2013 5.G Owner's Guide

GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers where the GCW of the towing
vehicle plus the trailer exceed the GVWR of the towing vehicle.The
GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight– is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer), and driver only (150 lb. [68 kg]).Consult
your authorized dealer (or theRV and Trailer Towing Guide
provided by your authorized dealer) for more detailed information.
WARNING:Do not exceed the GVWR or the GAWR specified on
the Safety Compliance Certification Label.
WARNING:Do not use replacement tires with lower load
carrying capacities than the original tires because they may lower
the vehicle’s GVWR and GAWR limitations. Replacement tires with a
higher limit than the original tires do not increase the GVWR and
GAWR limitations.
WARNING:Exceeding any vehicle weight rating limitation could
result in serious damage to the vehicle and/or personal injury.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
RECOMMENDED TOWING WEIGHTS
Your vehicle is capable of towing a trailer up to 1000 lb (454 kg) gross
trailer weight with a maximum tongue load of 100 lb (45 kg).Do not
towwith the Boss 302, Boss 302 Laguna Seca, GT Deluxe or Shelby
GT500 models; they are not rated to tow a trailer.
ESSENTIAL TOWING CHECKS
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1000 miles (1600 kilometers).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Service your vehicle more frequently if you tow a trailer. Refer to your
scheduled maintenance information.
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer to theLoad Carryingchapter.
Remember to account for the trailer tongue weight as part of the vehicle
load when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the
axle. Distribute the trailer load so 10–15% of the total trailer weight is on
the tongue.

Safety Chains
Always connect the safety chains to the vehicle’s hook retainers. To
connect the safety chains, cross them under the trailer tongue and allow
slack for turning corners.
If you use a rental trailer, follow the rental agency’s instructions.
Note:Never attach safety chains to the bumper.
Trailer Brakes
WARNING: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.
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.
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. Ensure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up the lamps.
Before Towing a Trailer
Practice turning, stopping and backing-up to get the feel of the
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers) and do not make full-throttle starts.
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
•Place the gearshift lever in P (Park) to aid in engine and transmission
cooling and A/C efficiency during hot weather while stopped in traffic.
•Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
Towing195

•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 the grade assist 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, place
wheel chocks under the trailer’s wheels.
WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift and
dollies or flatbed equipment. Do not tow with a slingbelt. Ford Motor
Company has not approved a slingbelt towing procedure. If the vehicle is
towed incorrectly, or by any other means, vehicle damage may occur.

BREAKING-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating.
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Combine errands and minimize stop-and-go driving.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Rev the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.
Driving Hints203
2013 05+ Mustang(197)
Owners Guide gf, 1st Printing
USA(fus)

•Drive a heavily loaded vehicle or tow a trailer.
•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 lb [180 kg] of weight carried).
•Add particular accessories to your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
WARNING:Drive through water in an emergency only, and not
as part of normal driving.
WARNING:Engine damage can occur if water enters the air
filter.
Note:Driving through deep water may allow water into the transmission
or air intake and can cause internal vehicle damage or cause it to stall.
Note:Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
wheel rims (for cars) or the bottom
of the hubs (for trucks).
When driving through water,
traction or brake capability may be
limited. Also, water may enter your
engine’s air intake and severely
damage your engine or your vehicle
may stall.
Wet brakes do not stop the vehicle
as quickly as dry brakes.

covers, the intake manifold or electrical components as grounding points.
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
1. Connect the positive (+) jumper
cable to the positive (+) terminal of
the discharged battery.
2. Connect the other end of the
positive (+) cable to the positive
(+) terminal of the assisting battery.
3. Connect the negative (-) cable to
the negative (-) terminal of the
assisting battery.
4. Make the final connection of the
negative (-) cable to an exposed
metal part of the stalled vehicle’s
engine, away from the battery and
the carburetor/fuel injection system.
Ensure that the cables are clear of fan blades, belts, moving parts of both
engines, or any fuel delivery system parts.
