Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

284 OperationAt the gas station
Open fuel filler flap1 by pushing at
the point indicated by the arrow.
The fuel filler flap springs open.

Turn fuel cap2 counterclockwise and
hold on to it until possible pressure is
released.

Take off fuel cap2 and place it into
holder3 located on the inside of the
fuel filler flap.
To prevent fuel vapors from escaping
into open air, fully insert filler nozzle
unit.

Only fill your tank until the filler nozzle
unit cuts out – do not top off or over-
fill.

Replace fuel cap by turning it clockwise
until it audibly engages.

Close the fuel filler flap.Warning!
G
Overfilling of the fuel tank may create pres-
sure in the system which could cause a gas-
oline fuel discharge. This could cause the
gasoline fuel to spray back out when remov-
ing the fuel pump nozzle, which could cause
personal injury.i
Make sure to close the fuel filler flap before
locking your vehicle as the flap locking pin pre-
vents closing after you have locked the vehicle.
i
Leaving the engine running and the fuel cap
open can cause the yellow fuel tank reserve
warning lamp to flash and the malfunction indi-
cator lampú(USA only) or the malfunction
indicator lamp±(Canada only) to illuminate.
See also “Practical hints” section (
page 345).
i
Only use premium unleaded gasoline with a
minimum Posted Octane Rating of 91 (average of
96 RON/86 MON). Information on gasoline
quality can normally be found on the fuel pump.
For more information on gasoline, see the Facto-
ry Approved Service Products pamphlet.


418 Practical hintsFlat tire
Detach the electric air pump.

Stow electrical plug3 and air hose4
behind flap1 and place the air pump
back in the trunk.Lowering the vehicle

Lower vehicle by turning crank coun-
terclockwise until vehicle is resting ful-
ly on its own weight.

Remove the jack.
1-5 Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of 96 lb-ft
(130 Nm).

Before storing the jack in the trunk, it
should be fully collapsed.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes, etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.i
Vehicles with Advanced TPMS*:
Do not activate the tire inflation pressure moni-
tor (page 309) until a full size wheel/tire with
functioning sensor has been placed back into
service on the vehicle.
Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).i
Wrap the damaged wheel in the protective
film that comes with the spare wheel and put the
wheel in the trunk.
You can also place the damaged wheel down into
the spare wheel well. In this case, you must stow
the luggage bowl in the trunk.


452 Technical dataFuels, coolants, lubricants etc.Premium unleaded gasoline
Fuel requirements
Only use premium unleaded fuel:
The octane number (posted at the pump)
m u s t b e 9 1 m i n . I t i s a n a v e r a g e o f b o t h t h e
Research Octane Number (RON) and the
Motor Octane Number (MON):
(RON+MON)/2. This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious per-
sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors can damage your
health.
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded gasoline is not avail-
able and low octane fuel is used, follow these
precautions:


Have the fuel tank only partially filled with
unleaded regular gasoline and fill up with
premium unleaded gasoline as soon as pos-
sible.


Avoid full throttle driving and abrupt acceler-
ation


Do not exceed an engine speed of 3000 rpm
if the vehicle is loaded with a light load such
as two persons and no luggage.


Do not exceed
2/3 of maximum accelerator
pedal position if the vehicle is fully loaded or
operating in mountainous terrain.
