is working to control the vehicle
on a low traction surface.
If the TCS indicator/warning light
comes on and stays on while
driving, the vehicle needs service.SeeCompetitive Driving Mode on
page 8-37,Traction Control System

System on page 8-36for more
information
Traction Control System
(TCS) OFF/StabiliTrak®
OFF Light
This light comes on when the
StabiliTrak system is turned off.
If the Traction Control System (TCS)
is off, wheel spin is not limited.
If the StabiliTrak system is off, the
system does not assist in controlling
the vehicle. Turn on the TCS and
the StabiliTrak system and the
warning light turns off.For SS models, if this light is on,
the vehicle is in Competitive Mode.
A warning also appears in the
DIC for StabiliTrak Competitive

Tire Pressure Light
For vehicles with a tire pressure light,
this light comes on briefly when the
engine is started and provides
information about tire pressures and
the Tire Pressure Monitoring System.
4-24 Instruments and Controls
When the Light is On Steady
This indicates that one or more of the
tires are significantly underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. SeeTire
Messages on page 4-36for more
information. Stop and check the tires
as soon as it is safe to do so.
If underinflated, inflate to the proper
pressure. SeeTire Pressure on
page 9-54for more information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
SeeTire Pressure Monitor
Operation on page 9-57for more
information.Engine Oil Pressure

Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice:Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.

Remaining Oil Life
This display shows an estimate
of the oil’s remaining useful life.
If Remaining Oil Life 99% is
displayed, that means 99% of

4-36 Instruments and Controls
Tire and Loading Information
Label
A vehicle specific Tire and
Loading Information label is
attached to the vehicle’s center
pillar (B-pillar). With the driver’s
door open, you will find the label
attached near the door lock post.The Tire and Loading Information
label shows the number of
occupant seating positions (A),
and the maximum vehicle
capacity weight (B) in kilograms
and pounds.
The Tire and Loading
Information label also shows the
tire size of the original equipment
tires (C) and the recommended
cold tire inflation pressures (D).
For more information on tires and
inflation seeTires on page 9-48
andTire Pressure on page 9-54.
There is also important loading
information on the Certification
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front
and rear axle. See “Certification
Label” later in this section.Steps for Determining Correct
Load Limit
1.Locate the statement
“The combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs” on your vehicle
placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1400 lbs and there will
be five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs
(1400−750 (5 x 150) = 650 lbs).
