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. Please contact gas station personnel in
case labels on the pump cannot be found.
For more information on gasoline, see
"Premium unleaded gasoline" (

page 306),
see "Fuel requirements" (

page 306), and
the, or contact an authorized smart center.
G
Warning!
Overfilling of the fuel tank may create
pressure in the system which could cause
a gas discharge. This could cause the gas
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury.

Tires and wheels
>> Operation
185 Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1) The Tire and Loading Information placard
can be found on the driver’s door B
pillar.
This placard tells you important informa

tion about the number of people that can
be in the vehicle and the total weight that
can be carried in the vehicle. It also con

tains information on the proper size and
recommended tire inflation pressures for
the original equipment tires on your vehi

cle.2) The certification label, also found on the
driver’s door B
pillar, tells you about the
gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating
(GAWR). The GAWR is the total allowable
weight that can be carried by a single axle
(front or rear). Never exceed the GVWR or
GAWR for either the front axle or rear
axle.

Driver’s door B
pillar
Following is a discussion on how to work with
the information contained on the Tire and
Loading Information placard with regards to
loading your vehicle.

Tires and wheels
>> Operation
189
Certification label
Even after careful determination of the
combined weight of all occupants and cargo as
to not exceed the permissible load limit, you
must make sure that your vehicle never
exceeds the Gross Vehicle Weight Rating
(GVWR) and the Gross Axle Weight Rating
(GAWR) for either the front or rear axle. You
can obtain the GVWR and GAWR from the
certification label. The certification label can
be found on the driver’s door B
pillar, see
"Technical data" (

page 293).
Gross Vehicle Weight Rating (GVWR) means:
the total weight of the vehicle, all occupants,
and all cargo must never exceed the GVWR.
Gross Axle Weight Rating (GAWR) means:
the total allowable weight that can be carried
by a single axle (front or rear).To assure that your vehicle does not exceed
the maximum permissible weight limits (GVWR
and GAWR for front and rear axle), have the
loaded vehicle (including driver, passenger,
and all cargo) weighed on a suitable commer

cial scale.
Recommended tire inflation
pressure
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door B
pillar (

page 185).
The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. The tires can be considered cold if the
vehicle has been parked for at least 3 hours
or driven less than 1 mile (1.6 km).
G
Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ

omy, and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are
more likely to become punctured or
damaged by road debris, potholes etc.
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
on the driver’s door B
pillar. Overload

ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.

Tires and wheels
>> Operation
191 Checking tire inflation pressure
Regularly check your tire inflation pressure
at least once a month.
Check and adjust the tire inflation pressure
when the tires are cold. The tires can be con

sidered cold if the vehicle has been parked
for at least 3 hours or driven less than 1 mile
(1.6 km).
If you check the tire inflation pressure when
the tires are warm (the vehicle has been
driven for several miles or sitting less than
3 hours), the reading will be approximately
4 psi (0.3 bar) higher than the cold reading.
This is normal. Do not let air out to match the
specified cold tire inflation pressure. Other

wise, the tire will be underinflated.Checking tire inflation pressure manually
Follow the steps below to achieve correct tire
inflation pressure:
>Remove the cap from the valve on one tire.
>Firmly press a tire gauge onto the valve.
>Read tire inflation pressure on tire gauge
and check against the recommended tire
inflation pressure on the Tire and Loading
Information placard on the driver’s door
B
pillar (

page 185). If necessary, add air
to achieve the recommended tire inflation
pressure.
i
If you have overfilled the tire, release tire
inflation pressure by pushing the metal stem
of the valve with e.g. a tip of a pen. Then
recheck the tire inflation pressure with the
tire gauge.
>Install the valve cap.
>Repeat this procedure for each tire.
G
Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ

omy, and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are
more likely to become punctured or
damaged by road debris, potholes etc.
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
on the driver’s door B
pillar. Overload

ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.

If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a malfunc

tion using the TPMS telltale flashing and illu

mination sequence.
The telltale extinguishes after a few minutes
driving if the malfunction has been corrected.
G
Warning!
Each tire should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard. If your vehicle has
tires of a different size than the size in

dicated on the Tire and Loading Informa

tion placard, you should determine the
proper tire inflation pressure for those
tires.
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi

nates a low tire pressure telltale when
one or more of your tires is significantly
underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly underinflated
tire causes the tire to overheat and can
lead to tire failure.
Underinflation also reduces fuel effi

ciency and tire tread life, and may affect
the vehicle’s handling and stopping
ability. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction indicator
is combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon subse

quent vehicle start
ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a vari

ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre

vent the TPMS from functioning properly.
Always check the TPMS malfunction tell

tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

>Press Restarting TPMS button1.
>The combination low tire pressure/TPMS
malfunction telltale in the instrument
cluster (

page 34) flashes for approxi

mately 5 seconds and then goes out.
After driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s specified
range. Afterwards the current tire inflation
pressures are accepted as reference
pressures and then monitored.Potential problems associated with
underinflated and overinflated tires
Underinflated tires
Underinflated tires can:
• cause excessive and uneven tire wear
• adversely affect fuel economy
• lead to tire failure from being overheated
• adversely affect handling characteristicsOverinflated tires
Overinflated tires can:
• adversely affect handling characteristics
• cause uneven tire wear
• be more prone to damage from road
hazards
• adversely affect ride comfort
