Driving and Operating 193See the infotainment manual for
information on that system or the
navigation system, if equipped,
including pairing and using a cell
phone.
Defensive Driving Defensive driving means “ always
expect the unexpected. ” The first
step in driving defensively is to wear
the safety belt. See Safety
Belts 0 70 .
.
Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready.
.
Allow enough following distance
between you and the driver in
front of you.
.
Focus on the task of driving.
Drunk Driving Death and injury associated with
drinking and driving is a global
tragedy. { WarningDrinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
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.

194 Driving and Operating
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 0 146 .
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. 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.
.
Antilock Brake System (ABS)
allows steering while braking.

Driving and Operating 203to the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation 0 29 .
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) 0 206 .
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 0 156 . 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 0 214 .{ WarningTurning 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.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/
STOP for longer than two seconds,
or press twice in five seconds.
ACC/ACCESSORY (Amber
Indicator Light) : This mode allows
you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after
five minutes to prevent battery
rundown.

212 Driving and Operating CautionSpinning 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 0 219 . Manual Mode Tap Shift
CautionDriving 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. To enter Permanent Tap Shift Mode:
1. Move the shift lever from
D (Drive) to M (Manual Mode).
While in Tap Shift Mode, the M
of the PRNDM section of the
instrument cluster will become
highlighted, and the current
gear is indicated.
2. Tap the left control toward the
driver to downshift, and the
right control toward the driver
to upshift. To shift to the lowest
available gear, press and hold
the left control.
3. To exit, move the shift lever
back to D (Drive).
With the shift lever in D (Drive) and
not in Permanent Tap Shift Mode,
the Tap Shift controls will activate a
temporary tap manual shift mode,
allowing the transmission to be
manually shifted. The vehicle exits
Temporary Tap Shift Mode after the
accelerator pedal is steady for
six seconds. Temporary Tap Shift
Mode holds a gear longer without
exiting when coasting, to provide
powertrain braking. The Temporary
