Driving
AdvanceTrac Sport Mode (if equipped)
The AdvanceTrac system provides an available sport mode on some
models. This can be selected utilizing the stability off button as shown in
the table above.
Sport mode is not intended for use on public roadways as this mode
provides less AdvanceTrac system intervention than when the default
ESC and traction control systems are on. Sport mode will allow more
spirited driving while the AdvanceTrac system is still enabled.
STEERING
Your vehicle is equipped with an electric power-assisted steering (EPAS)
system. There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
If the steering wanders or pulls, check for:
• an improperly inflated tire.
• uneven tire wear.
• loose or worn suspension components.
• loose or worn steering components.
• improper steering alignment.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
Selectable steering
You can select the desired steering feel through the message center. The
settings are:
• Standard: Default factory setting.
• Sport: Slightly higher effort required for steering with more road force
felt through the steering wheel.
• Comfort: Slightly less effort required for steering with less road force
felt through the steering wheel.
