Driving Information
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.
.On AWD vehicles, use Tour Mode
when conditions permit.
.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.
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 governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
.Do not use a phone in demanding
driving situations. Use a hands-free
method to place or receive
necessary phone calls.
.Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
.Designate a front seat passenger to
handle potential distractions.

. If you are towing a trailer, see
Driving Characteristics and Towing
Tips 0290.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking
brake is set before you leave it.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0290.
Shifting out of Park
This vehicle is equipped with an
electronic transmission. The shift lock
release button is designed to prevent
inadvertent shifting out of P (Park).
To shift out of P (Park):
1. Ensure the engine is running.
2. Apply the brake pedal. 3. Press and hold the shift lock
release button on the shift lever.
4. Move the shift lever to the desired position. For N (Neutral) hold the

until the N indicator
illuminates red.
5. The P indicator will turn white and the gear indicator will turn red
when the vehicle is no longer in
P (Park).
After releasing the shift lever, it will
return to the center position.
If the vehicle cannot shift from
P (Park), a Driver Information Center
(DIC) message may be displayed.
Check that the ignition is on, the
engine is running, the brake pedal is
applied, and the shift lock release
button is pressed when you are
attempting to shift out of P (park).
If all of these are met but the vehicle
will not shift out of P (Park), see your
dealer for service.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the vehicle
and ignite. Do not park 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 of its cylinders, or in reduced
cylinder operation mode, depending
on the driving conditions.
When less power is required, such as
cruising at a constant vehicle speed,
the system will operate in reduced
cylinder operation 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
freeway, the system will maintain
full-cylinder operation.

3. Pull the control toward you toshift. Pull the left control to
downshift, and the right control to
upshift.
To exit Permanent Tap Shift Mode: 1. To exit M (Manual Mode) and return to D (Drive), pull back on
the shift lever. The D in the shift
pattern will illuminate in red, and
the M will switch to white.
2. After releasing the shift lever, it will return to the center position.
M (Manual Mode) can be exited to
return to D (Drive) at any speed by
pulling the lever rearward from the
center position. It is not necessary to
stop the vehicle or shift to N (Neutral)
or P (Park) prior to shifting back to
D (Drive).
Temporary Tap Shift Mode
To enter Temporary Tap Shift Mode: 1. With the transmission in D (Drive) and not in Permanent Tap Shift
Mode, the Tap Shift controls will
activate a Temporary Tap Shift
Mode, allowing the transmission to
be manually shifted. 2. To deactivate, hold the right
control briefly. Automatic shifts
return after no manual shifts have
been done for seven to 10 seconds.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. This can
be used for sport driving or when
climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking.
The transmission will only allow
shifting into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). If shifting is
prevented for any reason, the M or D
will flash in the instrument cluster.
The transmission will not
automatically shift to the next higher
gear if the engine rpm is too high.
It will only automatically shift to the
next lower gear if the engine rpm is
much too low.

wheels only and may provide better
fuel economy.
