Radiator fan, engine compartment blowers
The engine-compartment blowers are mounted under the engine compartment lid.After the engine is switched off, the engine compartment temperature is monitored for approx. 30 minutes.During this period, and depending on temperature, the engine-compartment blowers may continue to run or start to run.fCarry out work in this area only with the engine off and exercise extreme caution.
The radiators and radiator fans are in the front of the vehicle.The radiator fans in the front of the vehicle may be operating or unexpectedly start operating when the engine is switched on.fCarry out work in these areas only with the engine switched off.fTake great care to ensure that parts of the body, items of clothing or jewelery cannot be drawn in by the radiator fan, engine-compartment blower, drive belt or other moving parts.
Measurements on test stands
Performance test
Performance tests on roller-type test stands are not approved by Porsche.
Brake tests
Brake tests must be performed only on roller-type test stands.
The following limit values must not be exceeded on roller-type test stands: – Test speed 4.7 mph (7.5 km/h)– Test duration 20 seconds
Testing the electric parking brake
Electric parking brake tests on the brake test stand must only be performed with the ignition switched on and with the Porsche Doppelkupplung selector lever in position N. The vehicle switches automatically to brake test stand mode, in which the electric parking brake can be tested.The message “ Electric parking brake in service mode ” appears on the multi-function display in the instrument panel.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire vehicle must be lifted and the wheels must be free to turn.
Engine Oil
It is important to perform oil changes regularly in accordance with the intervals specified in your Maintenance Schedule .
Engine oil consumption
It is normal for your engine to consume oil. The rate of oil consumption depends on the quality and viscosity of oil, the speed at which the engine is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the lubricant.
If the vehicle is used for repeated short trips, and consumes a normal amount of oil, the engine oil measurement may not show any drop in the oil level at all, even after 600 miles (1000 km) or more. This is because the oil is gradually becoming diluted with fuel or moisture, making it appear that the oil level has not changed. The diluting ingredients evaporate out when the vehicle is driven at high speeds, as on an expressway, making it then appear that oil is excessively consumed after driving at high speeds.
If the conditions you drive your vehicle in are dusty, humid, or hot, the frequency of the oil change intervals should be greater.
If the vehicle is driven at a high rate of speed, climatic conditions are warm, and the load is high, the oil should be checked more frequently, as driving conditions will determine the rate of oil consumption.– The engine in your vehicle depends on oil to lubricate and cool all of its moving parts. Therefore, the engine oil should be checked regularly and kept at the required level.– Make it a habit to have the engine oil level checked with every refueling.– The oil pressure warning light is not an oil level indicator. The oil pressure warning light indicates serious engine damage may be occurring when lit, if engine rpm is above idle speed.

232 Maintenance and Car Care
High-pressure cleaning equipment, steam cleaners
Risk of damage as a result of using high-pressure cleaning equipment, steam cleaners or similar.
High-pressure cleaning equipment, steam cleaners or similar can damage the following components:– Convertible top– Tires– Logos, emblems– Painted surfaces– Alternator– Electrical components and plug connections in the engine compartment– ParkAssist sensors– Radar sensor for adaptive cruise control– Reversing camerafAlways read the operating instructions provided by the equipment manufacturer.fAlways cover the lid of the brake fluid reservoir prior to cleaning. Never point the cleaning jet directly at the lid.fWhen cleaning with a flat-jet nozzle or a so-called “dirt blaster”, maintain a minimum distance of 20 in. (50 cm).fNever use high-pressure cleaning equipment or steam cleaners with a round-jet nozzle.A high-pressure cleaning device or steam cleaner fitted with a round nozzle will damage your vehicle. The tires are particularly susceptible to damage.fDo not point the cleaning jet directly at any of the aforementioned components.
Decorative film
Risk of damage due to separation of the decorative film when using high-pressure cleaning equipment, steam cleaners or similar cleaning equipment.fDo not use high-pressure cleaning equipment, steam cleaners, etc. to clean decorative films.
Care of door lock
fTo prevent the door lock from freezing during the cold season, cover the lock barrel with suitable adhesive tape while washing the vehicle.
If the lock still freezes, use an ordinary de-icer. In many cases, a well warmed key can help.fNever use excessive force.
Car washing
The best protection for the vehicle from the damaging effects of the environment is frequent washing and preservation.
The longer road salt, road dust, industrial dust, insect remains, bird excrement, and tree exudations (e.g. resin, pollen), etc. are allowed to remain on the bodywork, the more harmful their effect.
Observe the following points in order to ensure that the vehicle is washed thoroughly without damaging the paintwork: fThe underside of the vehicle should also be thoroughly washed at the end of the gritting season at the latest.fWash your vehicle only at sites provided for this purpose to prevent soot, grease, oil and heavy metals from entering the environment.
fNew cars should be washed carefully with plenty of clear water to protect the new paint work. Dark paint finishes show up the smallest of surface damage (e.g., scratches) more readily than lighter colors. Dark colors are slightly more susceptible to scratching and require particularly careful paint care.Dark paints make even the smallest surface blemishes (scratches) more conspicuous than lighter colors.fDo not wash your Porsche in direct sunlight or when its body is hot.fWhen washing by hand, use a car shampoo, plenty of water, and a soft sponge or washing brush.We recommend Porsche car shampoo.fStart washing the vehicle by thoroughly wetting the paintwork and rinsing the heavy dirt off.fAfter washing the vehicle, rinse it thoroughly with water and rub it dry with chamois-leather.Do not use the same chamois for rubbing dry as you use for cleaning the windshield and windows.
Reduced or uneven braking action may be caused by wet brakes.fAfter washing the vehicle, test the brakes and steering and briefly brake the disks dry.When doing so, make sure that vehicles traveling behind you are not affected.

Maintenance and Car Care 233
Cleaning in car washes
Optional add-on parts or parts that project beyond the contours of the vehicle may be damaged by design features of car washes.
The following parts are particularly at risk: – Convertible top (hot wax treatment must not be used, as the wax attacks the convertible top material),– Windshield wipers and rear wiper (always switch them off – wiper stalk in position 0 – to prevent them wiping unintentionally in intermittent or sensor operation).– Exterior mirrors (always fold in).– External antenna (always unscrew).– Roof transport system (always remove completely).– Spoilers.– Wheels (the wider the rim and the lower the tire height, the greater the risk of damage).– High-gloss or silk-gloss wheels (to prevent these from getting scratched, do not clean with the wheel-cleaning brushes of the car wash). fPlease consult the operator before using automatic car washes.fAll parts not reached by a car wash, such as door and lid seams or door sills, must be washed and polished by hand.
Information
Automatic car washes spray water at odd angles and high pressures, which are not seen in normal driving. Therefore, water can sometimes find its way into the passengers compartment during or shortly after the car wash.
Convertible top
The service life and appearance of the convertible top depend largely on expert care and operation.
Incorrect care and operation can damage the convertible top or cause it to leak.
Never remove snow and ice with sharp-edged objects.
Cleaning the convertible top
Risk of damage to the convertible top due to the cleaning jet of the high-pressure cleaning equipment or hot wax treatment. fDo not clean the convertible top with high-pressure cleaning equipment. fDo not use hot wax treatment.
Do not wash the convertible top every time you wash the vehicle.
Normally, rinsing the convertible top with clean water is sufficient.fBrush dust off the convertible top in the direction of the weave using a soft brush. fOnly in the case of heavy soiling, wet the convertible top with lukewarm water and a wash-shampoo & convertible-top cleaner and rub gently using a sponge or soft brush.Rinse off wash-shampoo & convertible-top cleaner thoroughly from the convertible top with clean water.We recommend Porsche wash-shampoo.fAfter washing, treat the convertible top at least once a year with a convertible-top care product.Do not allow the convertible-top care product to come into contact with paint or glass. If it does, remove immediately.
fIn the case of leakage in the convertible-top covering or at its seams and folds, use a convertible-top care product.fPlease observe the information on the containers.We recommend Porsche convertible-top care product.fRemove bird excrement immediately. The acid this contains makes the rubber swell and the convertible top will leak.fOpen the convertible top only when completely dry, otherwise damp stains and abrasion marks may occur which cannot be removed.fAttempt to remove spots from the convertible-top covering by rubbing carefully with a soft rubber sponge.

Maintenance and Car Care 235
Repairing the underbody protection
The underside of your car is durably protected against chemical and mechanical influences.
As it is not possible to exclude the risk of damage to this protective coating in day to day driving, it is advisable to have the underside of the car inspected at certain intervals - preferably before the start of winter and again in spring - and the undercoating restored as necessary.
Your authorized Porsche dealer is familiar with the bodyseal treatment procedures and has the necessary equipment for applying factory approved materials. We recommend that you entrust them with such work and inspections.
Unlike conventional spray oils, undercoating and rust-proofing compounds based on bitumen or wax do not attack the sound-proofing materials applied at the factory.
The exhaust system becomes very hot when the engine is running. Flammable material close to the exhaust system could ignite. Additional undercoating or rust protection agents on or near the exhaust system can become too hot when driving and ignite.fDo not apply additional undercoating or rust-proofing on or near the exhaust manifold, exhaust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite.
fBefore applying fresh underseal, carefully remove deposits or dirt and grease. Once it has dried, the new undercoating compound forms a tough protective coating which provides efficient rust-proofing of the floor panels and components.
fAlways apply a fresh coating of suitable preservative to unprotect areas after cleaning the underside of the body, the transmission, the engine or carrying out repairs to under-body, engine or transmission components.
Effective rust-proofing is particularly important during the cold weather season. If your car is driven frequently in areas where salt has been spread on the roads, the whole engine compartment should be cleaned thoroughly after the winter to prevent salt from causing any lasting damage. A full under-body wash should also be performed at the same time.
Cleaning headlights, lights, interior and exterior plastic components, adhesive foils, reversing camera and radar sensor for adaptive cruise control
Observe the following points: fUse only clean water and a little dishwashing liquid or interior window cleaner to clean headlights, lights, plastic components and surfaces.Use a soft sponge or a soft, lint-free cloth.fDo not spray water or interior window cleaner directly onto the plastic components in the passenger compartment, but first onto a sponge or cloth. Cleaning agents may, for example, enter controls or switches and cause damage.
Information
An interior window cleaner can also be used to clean plastic surfaces (always read the cleaning instructions on the container).We recommend Porsche interior window cleaner.fGently wipe the surface without applying too much pressure.fDo not clean when dry.
fNever use other chemical cleaners or solvents.fRinse cleaned surfaces with clear water.
Alloy wheels
Metal particles (e.g. brass or copper in brake dust) must not remain too long on alloy wheels.Contact corrosion can cause pitting.
Information
Cleaners with an oxide-removing effect or wrong pH value, as are commonly used for other metals, as well as mechanical tools and products, will damage the oxide layer and are therefore unsuitable.fUse only cleaners for alloy wheels (pH value 9.5). Products with the wrong pH value can destroy the protective layer on the wheels . We recommend Porsche cleaner for alloy rims.fIf possible, wash the wheels every two weeks with a sponge or washing brush. If the wheels are exposed to road salt, grit or industrial dust, weekly cleaning is necessary.fEvery three months, after cleaning, grease the wheels with car wax or an acid-free grease (e.g. Vaseline).Rub the grease in well with a soft cloth.fPlease see the chapter “CLEANING IN CAR WASHES” on page 233.

Improperly secured floor mats can obstruct pedal travel.fAlways check the movement of the pedals before driving and make sure that they are not obstructed by a floor mat or any other object.fSecure the floor mat to prevent it from sliding into positions that could interfere with the safe operation of your vehicle – do not lay them loosely in the vehicle.Your authorized Porsche dealer will be glad to offer you floor mats of correct size including a securing possibility.
Cleaning airbag covers
Incorrect modifications may damage the airbag system. The airbag may not deploy properly in the event of an accident.fDo not make any modifications whatsoever to individual components, such as the padded covers on the steering wheel, the instrument panel, the underside of the instrument panel, front seats and door panels.fHave your authorized Porsche dealer to clean these components.
Cleaning fabric linings
fFabric linings on pillars, roofliner and sun blinds, etc. must be cleaned only using suitable cleaning agents or a suitable dry foam and a soft brush.
Alcantara® care
Do not use leather care products to clean Alcantara®. Alcantara® is a manufactured product. It is not genuine leather or suede.
For regular care, it is sufficient to clean the cover with a soft brush.
Strong abrasion or rubbing when cleaning will produce a lasting change to the surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or thinned white spirit and dab the dirt from the outside in.
Cleaning the safety belts
fUse mild detergent to clean soiled belts.fWhen drying, avoid direct sunlight.fOnly use suitable cleaning agents.fDo not tint or bleach the belts.The belt fabric could be weakened, thus affecting safety.
Storing your Porsche
If you intend to store your Porsche for a prolonged period, please consult your authorized Porsche dealer. The staff will be glad to advise you on the most suitable and necessary methods. fClean your vehicle thoroughly inside and outside. The under carriage and chassis components should be free of dirt and salt deposits. fFill up the fuel tank. fChange the oil and oil filter, and run the engine for several minutes. fIncrease the tire pressure to 50 psi/3.5 bar/350 kPa.It is not recommended to lift the vehicle, due to the possibility of corrosion on shock absorber piston shafts.The vehicle should be moved slightly, approximately every four weeks, to prevent flat spot on the tires.

248 Minor Repairs
Tire life
Tire life depends on various factors, i.e., road surfaces, traffic and weather conditions, driving habits, type of tires and tire care.fInspect your tires for wear and damage before driving off. If you notice uneven or substantial wear, wheels might need alignment or tires should be balanced or replaced.
Tire wear
The original equipment tires on your Porsche have built-in tire wear indicators. They are molded into the bottom of the tread grooves and will appear as approximately 1/2 in. (12 mm) bands when the tire tread depth is down to 1/16 of an in (1.6 mm).
When the indicators appear in two or more adjacent grooves, it is time to replace the tires. We recommend, however, that you do not let the tires wear down to this extent. Worn tires cannot grip the road surface properly and are even less effective on wet roads.
In the United States, state laws may govern the minimum tread depth permissible. Follow all such laws.
Driving on worn tires can result in loss of control of the vehicle and could cause serious personal injuries or death.fDo not drive with worn tires or tires showing cuts or bruises as they may lead to sudden deflation and loss of control which could cause severe personal injury.fSpecialized high performance tires on high performance sports cars exhibit more wear than those on a family sedan, or even a high performance sedan. Therefore, it is important to check your tire
pressure and condition at least every two weeks.
fIf you notice that tires are wearing unevenly, consult your authorized Porsche dealer.
Uneven wear may not always be due to improper wheel alignment. It can be the result of individual driving habits such as cornering at high speeds. If the tire pressure is not checked and adjusted regularly, abnormal tire wear can also occur.
Tire care
fAvoid damaging tires and wheel rims.fIf you must drive over a curb or other obstacle, drive slowly and at an obtuse angle.fCheck tires for uneven wear and damage before driving off.fRemove embedded material.fReplace worn or damaged tires immediately.fKeep oil, fuel, brake fluid, etc. away from tires.fReplace missing valve stem caps.fKeep tires inflated correctly.fWash tires when washing the vehicle. Also clean inner side of wheels.fDo not use abrasive cleaners when washing the wheels.fCheck wheel rims for corrosion.fRemove road salt, if driving in winter.
Tire damage, puncture
fPlease see the chapter “HIGH-PRESSURE CLEANING EQUIPMENT, STEAM CLEANERS” on page 232.
Driving the vehicle with low tire pressure increases risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases the rate of wear of the affected tires.fCheck tires – including sidewalls – regularly for foreign bodies, nicks, cuts, cracks and bulges.fAfter driving off road, examine tires for signs of damage such as cuts, tears, bulges or foreign objects stuck in the tread. Replace a damaged tire if necessary.fCross curb edges slowly and at right angles if possible. Avoid driving over steep or sharp curbs.fIn cases of doubt, have the wheel (particularly the inner side) checked by an authorized Porsche dealer.
In case of tire damage, where it is uncertain whether there is a break in the ply with all its consequences or tire damage caused by thermal or mechanical overloading due to loss of pressure or any other prior damage, we recommend that the tire be replaced for safety reasons.
If one faulty tire is replaced it should be noted that the difference in tread depth on one axle must not exceed 30%. Handling inconsistencies may result.fRecommendation: Replace both tires on one axle so that no handling inconsistencies may result due to different tread depths.fPerform a visual inspection if necessary.

250 Minor Repairs
Wheel alignment, wheel balancing
As a precaution, have wheels with summer tires balanced in the spring, and those with mud and snow tires before winter. Unbalanced wheels may affect car handling and tire life.Only the specified weights may be used for wheel balancing.
Self-adhesive weights must not come into contact with cleaning agents, since they could drop off.Uneven tread wear indicates wheel imbalance. In this event, the vehicle should be checked at an authorized Porsche dealer.
If, during a trip, uneven running or vibrations occur that could be caused by damage to tires or the car, the speed must be reduced immediately, but without braking sharply. If you continue your trip without having the cause of the fault remedied, you might lose control of your vehicle.fStop the vehicle and check the tires.fIf no cause for the fault can be found, drive carefully to the nearest authorized Porsche dealer.
The summer tires of your Sports Car have been specially developed and adapted for high performance. At low outside temperatures (<15°C (60°F)), the tire characteristics change. This can result in noises occurring when parking or maneuvering at low outside temperatures.
Wheels with Tire Pressure Monitoring System (TPMS) sensors
Before changing wheels, make sure that the wheels are compatible with your vehicle’s TPMS.fCheck this with your authorized Porsche dealer.
Removing and storing tires
fAfter changing, adjust tire pressure and torque wheel bolts diagonally. Please see the chapter “CHANGING WHEELS” on page 254.fStore tires in a cool and dry place. Rotate periodically to avoid flat spots.fDo not store summer tires or park vehicles fitted with summer tires at ambient temperatures below 5 °F (-15 °C).fAvoid contact with fuel, oil and grease.
Tires must always remain on the same side of the vehicle.When wheels are removed, the direction of rotation and position of each wheel should be marked.
Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with their marking.
The perception that tire durability and performance are not affected by storage and age is unfounded. Chemical additives, which make the rubber elastic, lose their effectiveness over the course of time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from time to time.
Information
Under no circumstances should tires older than 6 years be used on your Porsche.
The age of the tire can be obtained from the “DOT” code number. If, for example, the last four numbers read 1213, then the tire was produced in the 12th week of 2013.
Snow tires
The installation of Porsche approved snow tires is recommended.
Use Porsche approved snow tires for grip on snow and ice. Summer performance tires are not suitable for usage in cold, snowy, or icy conditions.Check with your local Motor Vehicle Bureau for possible restrictions.
