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.
.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.

DRIVING AND OPERATING 211
Warning (Continued)
serious—or even fatal —collision
if you drive after drinking or taking
drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has been
drinking or is impaired by drugs.
Find alternate transportation home;
or if you are with a group, designate
a driver who will remain sober.
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 or a brake
fault occurs, the brakes may lose
power assist. More effort will be
required to stop the vehicle and it can
take longer to stop.
Steering
Caution
To avoid damage to the steering
system, do not drive over curbs,
parking barriers, or similar objects
at speeds greater than 3 km/h
(1 mph). Use care when driving over
other objects such as lane dividers
and speed bumps. Damage caused
by misuse of the vehicle is not
covered by the vehicle warranty.
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.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.

antenna signal causing interference to
the Keyless Access system. SeeRemote
Keyless Entry (RKE) System Operation
0 7.
To shift out of P (Park), the vehicle
must be on 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) 0237.
If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
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) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{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.
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 within five seconds.

remains on. If the amber service
parking brake warning light is on, see
your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is pressed. If the
switch is pressed until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This is normal,
and is done to periodically check the
correct operation of the EPB system,
or at the request of other safety
functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red
parking brake status light is off. If the amber service parking brake
warning light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the
red parking brake status light is off.
If either light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0315.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life. The EPB can also be used to prevent
roll back for vehicles with a manual
transmission taking off on a hill.
When no roll back is desired, an
applied EPB will allow both feet to be
used for the clutch and accelerator
pedals in preparation for starting the
vehicle moving in the intended
direction. In this case, there is no
need to press the switch to release
the EPB.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.

256 DRIVING AND OPERATING
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature.
HSA does not replace the need to
pay attention and drive safely. You
may not hear or feel alerts or
warnings provided by this system.
Failure to use proper care when
driving may result in injury, death,
or vehicle damage. SeeDefensive
Driving 0210.
When the vehicle is stopped on a
grade, Hill Start Assist (HSA)
temporarily prevents the vehicle from
rolling in an unintended direction
during the transition from brake pedal
release to accelerator pedal apply. The
brakes release when the accelerator
pedal is applied or automatically
release after a few seconds. The brakes
may also release under other
conditions. Do not rely on HSA to
hold the vehicle.
HSA is available when the vehicle is
facing uphill in a forward gear,
or when facing downhill in R (Reverse). The vehicle must come to
a complete stop on a grade for HSA to
activate.Automatic Vehicle
Hold (AVH)
{Warning
Do not rely on this feature. It does
not replace the need to pay
attention and drive safely. You may
not hear or feel alerts or warnings
provided by this system. Failure to
use proper care when driving may
result in injury, death, or vehicle
damage.When Automatic Vehicle Hold (AVH)
is turned on and the vehicle is braked
to a stop, AVH prevents the vehicle
from moving during the transition
from brake pedal release to accelerator
pedal apply. The brakes release when
the accelerator pedal is applied. The
brakes may also release under other
conditions. Do not rely on AVH to
hold the vehicle.
If the accelerator pedal is not applied
within a few minutes, the Electric
Parking Brake will apply. The parking
brake will also apply if the driver door
is opened or the driver seat belt is
unfastened while AVH is holding the
vehicle.
AVH can be turned on by pressing
AUTO HOLD. The indicator light on
the switch will come on. The AVH
light on the instrument panel will
