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 under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as pos-
sible, and inflate them to the proper pres-
sure. Driving on a significantly
underinflated tire causes the tire to over-
heat and can lead to tire failure.
Continued
Warning (Continued)
G
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the ve-
hicle’s handling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if underinflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure tell-
tale.
Continued
Warning (Continued)
G
USA only: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 re-
main continuously illuminated. This se-
quence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be able to de-
tect or signal low tire pressure as intended.

Warning
G
The TPMS does not warn you against in-
correctly selected tire inflation pressure
and does not warn you when the tire pres-
sure is not properly selected for the re-
spective vehicle load. It warns you only
when the pressure of one or more tires
decreases significantly below the refer-
ence inflation pressure which was stored
at the time of calibration of the TPMS af-
ter you inflated the tires.Always ensure that you recalibrate the
TPMS after you have inflated the tires to
the recommended cold inflation pressure.
Continued
Warning (Continued)
G
Always adjust the tire inflation pressure
according to the tire and loading informa-
tion placard on the driver’s door B-pillar.Underinflated tires wear excessively and/
or unevenly, adversely affect handling and
fuel economy, and are more likely to fail
from being overheated.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.
Continued
Warning (Continued)
G
The TPMS is not able to issue a warning
due to a sudden dramatic loss of pressure
(e.g. tire blowout caused by a foreign ob-
ject). In this case bring the vehicle to a
halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.

Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure rec-

on the vehicle placard or the tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or the tire inflation
pressure label, you should determine the
proper tire inflation pressure for those
tires).

1. Safety 2. Economy
Improper inflation pressures can cause
uneven wear patterns to develop across
the tire tread. These abnormal wear pat-
terns will reduce tread life resulting in a
need for earlier tire replacement. Under-
inflation also increases tire rolling resis-
tance and results in higher fuel
consumption.
Warning
G
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly, ad-
versely affect handling and fuel economy,
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride com-
fort, wear unevenly, increase stopping dis-
tance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road de-
bris, potholes etc.
Warning
G
Improperly inflated tires are dangerous
and can cause accidents.
Unequal tire inflation pressures can
cause steering problems. You could lose
control of your vehicle.
Unequal tire inflation pressures from one
side of the vehicle to the other can cause
the vehicle to drift to the right or left. Al-
ways drive with each tire inflated to the
recommended cold tire inflation pres-
sure.

Do not blend other specific fuel addi-
tives with diesel fuel except for fuel flow
improver. They only result in unneces-
sary cost, and may be harmful to the en-
gine operation.
Flow improversThe effectiveness of flow improvers can-
not be guaranteed with all fuels. Ob-
serve the mixing ratio and comply with
the handling instructions given from the
manufacturer.
Warning
G
Under no circumstances should gasoline
be mixed with diesel fuel.
Due to the high pressure and high temper-
ature in the injection system, there is a
risk of fire and explosion.In addition, there is a risk of engine damage.Always follow basic safety rules when
working with any combustible material.
