2004 PORSCHE CAYENNE fuel consumption

6Break in hints for the first
2,000 miles (3,000 kilometers)The following tips will be helpful in obtaining
optimum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, the moving parts must still wear
in with each other. This wearing-in occurs mainly in
the first 2,000 miles (3,000 km).Therefore:fPreferably take longer trips.
fAvoid frequent cold starts with short-distance
driving whenever possible.
fAvoid full throttle starts and abrupt stops.
fDo not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
fDo not run a cold engine at high rpm either in
Neutral or in gear.
fDo not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
fNever lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period.fDo not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles (3,000 kilometers).
There may be a slight stiffness in the steering,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and brake discsNew brake pads and discs have to be “broken in”,
and therefore only attain optimal friction when the
car has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This also applies whenever the brake pads
and brake discs are replaced.New tiresNew tires do not have maximum traction. They
tend to be slippery.
fBreak in new tires by driving at moderate
speeds during the first 60 to 120 miles (100
to 200 km). Longer braking distances must be
anticipated.
Engine oil and fuel consumptionDuring the break-in period oil and fuel consump-
tion may be higher than normal.
fPlease see the chapter “ENGINE DATA” on
Page 349.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road
conditions, as well as the amount of dilution and
oxidation of the lubricant.
fMake a habit of checking engine oil with every
refueling, add if necessary.

Displaying/resetting average
speed
Displaying range on remaining fuelThe range on remaining fuel is continuously
recomputed while driving based on fuel level,
current consumption and average consumption.
Displaying tire pressureThis display is available only in conjunction with the
Tire Pressure Monitoring option.
The current tire pressures at the actually present
levels are displayed in the “Tyre pressure” screen
of the on-board computer. These values would be
identical to those of a pressure gage connected to
the four valves. These pressures change while the
vehicle is being driven.
– The tire pressures increase as the temperature
in the tires rises, e.g. during high-speed
motorway driving.
– The tire pressures decrease as the tempera-
tures drop, e.g. during trips in cold regions
(such as mountains).
The values displayed therefore do not allow
conclusions to be drawn about possible pressure
deviations.
fIn order to display pressure deviations from
the prescribed pressure, select the menu item
TYRE PRESS. in the MAIN MENU.

Off-road roof-mounted Headlights
Cayenne S TranssyberiafPlease read the separate instructions for fitting
and operating the off-road roof-mounted
headlights.DisclaimerThe off-road roof-mounted headlights provided
with your Cayenne S Transsyberia have been
designed and manufactured solely for off-road
use. The use of these lights while on a public road
in your country may not be legal or may be legal
only under specified conditions. Check your
national, state/provincial and local laws or
regulations regarding any restrictions and/or
limitations for public highway use prior to
installation. It is common in many countries, for
example, that such roof-mounted headlights must
be hooded or covered while you are on a public
road.
Under no circumstances should the electrical
circuits for these lights be connected to the
circuits for the other lights provided with your
vehicle.
Safety Notes!
fCompletely remove the off-road roof-mounted
headlights before using an automatic car wash
– risk of damage to the vehicle!
fBefore every trip, and at regular intervals
during long trips, check that the off-road
roof-mounted headlights are secured to the
vehicle properly.
fWith the off-road roof-mounted headlights
fitted, do not exceed a maximum speed of
110 mph (180 km/h).
Nevertheless, Porsche recommends that you
do not exceed the posted speed limit.
fDriving, braking and steering behaviour
change due to the higher center of gravity and
the greater wind-resistant area. You should
adapt your driving style appropriately.
fSince fuel consumption and noise are
increased when the off-road roof-mounted
headlights are fitted, they should not remain on the vehicle when not in use.
Note on operation
If the engine is not running and the off-road
roof-mounted headlights are switched on, the
vehicle battery will be discharged.
Switching the off-road roof-mounted
headlights on/offThe off-road roof-mounted headlights are ready for
operation when the side lights are switched on.

Radiator fansThe radiator and radiator fans are in the front of
the car.
Warning!
Danger of injury. The fans can start running
as a function of temperature, even with the
engine switched off.
fExercise extreme caution when working in the area of the radiator fans.
Engine OilIt is important to perform oil changes regularly in
accordance with the intervals specified in your
Maintenance Schedule.Engine oil consumptionIt 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 le-
vel 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 express-
way, 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 lu-
bricate and cool all of its moving parts. There-
fore, the engine oil should be checked regular-
ly 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 occuring when lit, if
engine rpm is above idle speed.

The catalytic converters will be damaged by:
– push or tow starting the vehicle
– misfiring of the engine
– turning off the ignition while the vehicle is
moving or
– driving until the fuel tank is completely empty
– by other unusual operating conditions.
fDo not continue to operate your vehicle under
these conditions, since raw fuel might reach
the catalytic converters. This could result in
overheating of the converters. Federal law
prohibits use of leaded fuel in this car.
Fuel EconomyFuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications. Air
cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated to the correct
pressure.
fAlways monitor your fuel consumption.
fDrive smoothly, avoid abrupt changes in speed
as much as possible.
fAvoid jack rabbit starts and sudden stops.
fDo not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
fProlonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.fSwitch off the engine if stationary for longer
periods.
fAny additional weight carried in the vehicle
re d u c e s f u e l e c o n o m y. A l w a ys k e e p c a rg o t o a
minimum and remove all unnecessary items.
fOrganize your trips to take in several errands
in one trip.
fAll electrical accessories contribute to
increased fuel consumption.
fOnly switch on the air conditioning when neces-
sary.
fDo not drive with the Roof Transport System
mounted unless you need it.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage will probably be less
than the estimated mpg.
fPlease see all local and national speed limits.
