REDUCED ACCELERATION
DRIVE WITH CARE
This message displays when the
vehicle propulsion power is
reduced. A reduction in propulsion
power can affect the vehicle's ability
to accelerate. If this message is on,
but there is no observed reduction
in performance, proceed to your
destination. Under certain
conditions, the performance may be
reduced the next time the vehicle is
driven. The vehicle may be driven
while this message is on, but
maximum acceleration and speed
may be reduced. Anytime this
message stays on, or displays
repeatedly, the vehicle should be
taken to your dealer for service as
soon as possible.
Under certain operating conditions,
propulsion will be disabled. Try
restarting after the ignition has been
off for two minutes.
Vehicle Speed Messages
SPEED LIMITED TO XXX KM/
H (MPH)
This message shows that the
vehicle speed has been limited to
the speed displayed. The limited
speed is a protection for various
propulsion and vehicle systems,
such as lubrication, thermal, brakes,
suspension, Teen Driver (if
equipped), or tires.

If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
If the steering wheel is turned until it
reaches the maximum rotation and
is held at that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See your dealer if there is a
problem.
Dynamic Rack Travel
If equipped with Magnetic Ride
Control, Dynamic Rack Travel
(DRT) is a steering system feature
which enhances driving by providing
additional maximum steering wheel
rotation to allow a tighter turning
radius during low speed driving
conditions. If the vehicle speedincreases or if the suspension
encounters significant wheel travel,
such as a driveway, while at
maximum steering rotation, DRT
may gently push the steering back a
small amount to prevent the front
tires from contacting the vehicle.
This is normal operation. There is
no customer interface or display for
this feature. DRT is not available
when in Track Mode.
Curve Tips
.
Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable and
steady speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.
There are some situations when
steering around a problem may
be more effective than braking. .
Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:

Hill Rollback Control
If the vehicle is in gear and
inadvertently rolls backwards, Hill
Rollback Control helps limit the
rollback to a very low speed.
A noise may be heard while the
vehicle speed is actively being
controlled. A Driver Information
Center (DIC) message displays
when active.
Driver Mode Control
Driver Mode Control (DMC) adds a
sportier feel, provides a more
comfortable ride, or assists in different weather conditions or
terrain. This system simultaneously
changes the software settings of
various sub-systems to optimize
driving performance. Depending on
the option package, available
features, and mode selection; the
Exhaust, Suspension, Steering,
Brakes, and Powertrain will change
settings to achieve the desired
mode characteristics. If the vehicle
is equipped with Magnetic Ride
Control, selecting the various driver
modes adjusts the ride of the
vehicle to enhance the ride
performance for the road conditions
and the selected mode.
Driver Mode Control has multiple
modes: My Mode, Weather, Tour,
Sport, Track, and Z-Mode.
Weather, Tour, Sport, and Track are
four modes that have preset vehicle
setting for use in different driving
conditions. My Mode and Z-Mode
are two modes which can be
customized by the driver. In these
two modes, vehicle settings are
configured to enhance and
personalize the driving experience.
See
“Mode Description,” later in this
section.
Mode Activation
To activate My Mode, Weather, Tour,
Sport and Track Mode, turn the
Driver Mode Control (DMC) knob on
the center console to make a mode
selection. When a mode is selected,
an indicator will be displayed in the
Driver Information Center (DIC)i.

vehicle in ACC/ACCESSORY mode,
then press and hold the button on
the center console for 10
consecutive seconds to
automatically raise the vehicle.
The DIC may display the message
“Lift System Unavailable” if the
following occur:
. Any doors are ajar.
. The hood is open. .
The vehicle is moving over
38 km/h (24 mph).
. Too many lift requests within a
short period.
The Front Lift System should not be

Competitive Driving Mode
If equipped, Competitive Driving
Mode, PTM, and Launch Control are
systems designed to allow
increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and
suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
They will not compensate for driver
inexperience or lack of familiarity
with the race track. Drivers who
prefer to allow the system to have
more control of the engine, brakes, and suspension are advised to turn
the normal traction control and
StabiliTrak/ESC systems on.
Competitive Driving Mode
Competitive Driving Mode allows full
engine power while StabiliTrak/ESC
helps maintain directional control of
the vehicle by selective brake
application. In this mode, the TCS is
off and Launch Control is available.
Adjust your driving style to account
for the available engine power. See
“Launch Control”
later in this
section.

people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the transmission inP (Park).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
