Driving for Better Fuel
Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible:
. Set the climate controls to the
desired temperature after the
engine is started, or turn them
off when not required.
. Avoid fast starts and accelerate
smoothly.
. Brake gradually and avoid
abrupt stops.
. Avoid idling the engine for long
periods of time.
. When road and weather
conditions are appropriate, use
cruise control.
. Always follow posted speed
limits or drive more slowly when
conditions require.
. Keep vehicle tires properly
inflated. .
Combine several trips into a
single trip.
. Replace the vehicle's tires with
the same TPC Spec number
molded into the tire's sidewall
near the size.
. Follow recommended scheduled
maintenance.
. Using Tour mode rather than
Sport or Track modes, will result
in better Active Fuel
Management operation. See
Active Fuel Management 0169.
. For recommended shift speeds,
see Dual Clutch Transmission
0 171.
Premium Fuel
Use the recommended fuel. See
Recommended Fuel 0204.
Distracted Driving
Distraction comes in many forms
and can take your focus from the
task of driving. Exercise good
judgment and do not let other
activities divert your attention away
from the road. Many local

Driving and Operating 149
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

over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management
This vehicle's engine may be
equipped with Active Fuel
Management, which allows the
engine to operate on either all or
half of its cylinders, depending on
the driving conditions.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, passing,
or merging onto a highway, the
system will maintain full-cylinder
operation.
If the vehicle has an Active Fuel
Management indicator, see Driver
Information Center (DIC) for more
information on using this display.
Extended Parking
It is best not to park with the vehicle
running. If the vehicle is left running,
be sure it will not move and there is
adequate ventilation.

The Manual Paddle Shift system
can be deactivated by pulling the
D (Drive) switch on the center
console.
With the transmission in D (Drive),
pull the right + paddle or the left
− paddle to place the transmission
in Temporary Manual Paddle
Shift mode.
To exit Temporary Manual Paddle
Shift mode do one of the following:
. Hold the + paddle for more than
one second.
. Drive at a steady speed without
manual shifts or aggressive
cornering for more than
six seconds.
. Bring the vehicle to a stop. While the Manual Paddle Shift
feature is active, the transmission
will automatically downshift through
the gears as the vehicle slows. The
transmission will select 1 (First) gear
as the vehicle stops. From a stop,
the vehicle will start from and hold
1 (First) gear unless Manual Paddle
Shifts are used to shift into a
different gear, or D (Drive) is
selected.
To cause the transmission to
downshift to the lowest gear
possible for the vehicle speed, in
Manual Paddle Shift or Temporary
Manual Paddle Shift mode:
.
Pull and briefly hold the
−paddle. If the paddle continues
to be held as the vehicle slows,
downshifts will continue as
vehicle speed allows.
The Manual Paddle Shift system will
not allow an upshift or a downshift if
vehicle speed is too fast or too slow,
nor will it allow a start from any gear
other than 1 (First) gear.
When in Manual Paddle Shift mode,
if upshifting does not occur when
needed, vehicle speed will be limited to protect the engine. When
in Temporary Manual Paddle Shift
mode, the transmission will
automatically upshift if the
accelerator pedal is pressed all the
way to the floor.
Manual Paddle Shift can be used
with cruise control. See
Cruise
Control 0196.
The vehicle speeds required for
Manual Paddle Shift upshifts
depend on several vehicle inputs,
which will vary the allowed upshift
speed by a few km/h (mph).
To prevent damage to the
powertrain, Manual Paddle
downshifts to a lower gear cannot
be done above certain speeds.
