VEHICLE AGAIN
This message displays to indicate that
the steering column lock device was
unable to unlock the column, and the
engine did not start. If this happens,
immediately turn the steering wheel
from side to side. If that does not
unlock the steering column, turn the
ignition off, and then open the driver
door. Then turn the vehicle back on
and turn the steering wheel from side
to side for about 15 seconds. The
steering column must be turned to
each side immediately after pressing
ENGINE START/STOP to help the
steering column lock device unlock
the column. In some situations it may
take significant force. This situation
may be avoided by straightening the
front wheels before turning off the
engine.

186 DRIVING AND OPERATING
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is about
three-quarters of a second. In that
time, a vehicle moving at 100 km/h
(60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied. Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.
Steering
Variable Effort Steering
The vehicle has a steering system that
varies the amount of effort required to
steer the vehicle in relation to the
speed of the vehicle.
The amount of steering effort required
is less at slower speeds to make the
vehicle more maneuverable and easier
to park. At faster speeds, the steering
effort increases to provide a sport-like
feel to the steering. This provides
maximum control and stability.
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort. See your dealer if there is a
problem.If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If steering assist is used for an
extended period of time, power assist
may be reduced.
Normal use of the power steering
assist should return when the system
cools down.
See specific vehicle steering messages
under
Vehicle Messages 0141.
See your dealer if there is a problem.
Curve Tips
. Take curves at a reasonable speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of the
curve before accelerating gently
into the straightaway.

DRIVING AND OPERATING 195
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
Pressing the button cycles it through
three modes: ACC/ACCESSORY, ON/
RUN/START, and Stopping the
Engine/OFF.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. SeeRemote
Keyless Entry (RKE) System
Operation 029. To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or ON/
RUN, and the brake pedal must be
applied.
Stopping the Engine/OFF (No
Indicator Lights) :
When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0198.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
See Transmission Messages 0151.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags. If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn off the
ignition.
4. Set the parking brake. See Electric Parking Brake 0205.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.

DRIVING AND OPERATING 203
D :This position is for normal driving.
It provides the best fuel economy.
If you need more power for passing,
and you are:
. Going less than 55 km/h (35 mph),
push the accelerator pedal about
halfway down.
. Going about 55 km/h (35 mph) or
more, push the accelerator all the
way down.
The transmission will shift down
to a lower gear and have more
power.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Skidding”underLoss
of Control 0187.
M : This mode can be entered by
moving the shift lever from D (Drive)
to M (Manual Mode). M (Manual
Mode) allows the driver to select gears
appropriate for current driving
conditions. M (Manual Mode) can be
exited by returning the shift lever to
D (Drive). See Manual Mode0203.Caution
Spinning the tires or holding the
vehicle in one place on a hill using
only the accelerator pedal may
damage the transmission. The
repair will not be covered by the
vehicle warranty. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes to
hold the vehicle in place.
While in Sport Mode, the vehicle
monitors driving behavior and
automatically enables performance
shift features when spirited driving is
detected. These features maintain
lower transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit these features and return to
normal operation after a short period
when no spirited driving is detected.
See Driver Mode Control 0209.
Manual Mode
Tap Shift
Caution
Driving with the engine at a high
rpm without upshifting while using
Tap Shift, could damage the vehicle.
Always upshift when necessary
while using Tap Shift.
Vehicles with Tap Shift have controls
on the back of the steering wheel to
manually shift the automatic
transmission.

210 DRIVING AND OPERATING
system simultaneously changes the
software calibration of various
sub-systems. Depending on the option
package, available features, and mode
selected, the suspension, steering, and
powertrain will change calibrations to
achieve the desired mode
characteristics.
Press and release MODE on the center
console to activate the mode menu in
the instrument cluster. The first press
of the button will show the current
mode. Subsequent presses will scroll
through the available modes. Select a
new setting whenever driving
conditions change. The following
modes are available:
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
If the vehicle is equipped with AWD,
the Tour Mode is in between the Sport
and the Snow/Ice Modes for a more
balanced feel.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator will display in the Driver
Information Center (DIC).
When in Sport Mode, the vehicle will
shift automatically but may hold a
lower gear longer than it would in the
normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. SeeAutomatic
Transmission 0201. The steering,
including Active Rear Steer (if
equipped), will change to provide
more precise control.
If the vehicle is equipped with AWD,
the Sport Mode sends more torque to
the rear wheels.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. Snow/Ice
Mode will use a different accelerator
pedal map in order to optimize
traction on slippery surfaces.
When selected, the Snow/Ice Mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the
Vehicle Is Stuck 0190.
If the vehicle is equipped with AWD,
the Snow/Ice Mode will provide more
torque to the front wheels.
