Driving and Operating 9-15
Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions (Key
Access)
The ignition switch has four different
positions.
Notice:Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in, and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer.
The key must be fully extended to
start the vehicle.
To shift out of P (Park), turn the
ignition to ON/RUN and apply the
brake pedal.
1 (STOPPING THE ENGINE/LOCK/
OFF):
When the vehicle is stopped,
turn the ignition switch to LOCK/
OFF to turn the engine off. Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) on page 9‑23 for more
information.
This is the only position from which
the key can be removed. This locks
the steering wheel, ignition, and
automatic transmission.
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 neutral. This can be done while the vehicle is
moving. After shifting to 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 to LOCK/OFF.
4. Set the parking brake. See Parking Brake on page 9‑32.

9-16 Driving and Operating
{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,
turn the ignition to ACC/
ACCESSORY.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from right
to left while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service.
2 (ACC/ACCESSORY): This
position unlocks the steering wheel.
Some accessories can be used in
this position. 3 (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, as well as to display
some warning and indicator lights.
This position can also be used for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes.
The battery could be drained if the
key is left in the ON/RUN position
with the engine off. The vehicle
might not start if the battery is
allowed to drain for an extended
period of time.
4 (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
If the ignition becomes difficult to
turn, see Keys on page 2‑1.
Key Lock Release
Vehicles with an automatic
transmission are equipped with an
electronic key lock release system.
This system is to prevent ignition
key removal unless the shift lever is
in P (Park).

9-32 Driving and Operating
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch for the
EPB is on the center console. The
EPB can always be activated, even
if the ignition is off. To prevent
draining the battery, avoid repeated
cycles of the EPB system when the
engine is not running.
The system has a parking brake
status light and a parking brake
warning light. See
Electric Parking
Brake Light on page 5‑18. There are
also three parking brake related

GS Mode
.Additional stiffness in the shock
absorbers for increased body
control.
.The powertrain reacts more
quickly to the accelerator pedal.
.Power steering assistance is
reduced.
There is no automatic Drive Mode
Control (DMC) in this vehicle.
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
On vehicles with the Traction
Control System (TCS) or StabiliTrak,
the system may begin to limit wheel
spin while you are using cruise
control. If this happens, the cruise
control will automatically disengage.
See Traction Control System (TCS)
on page 9‑35 orStabiliTrak
®System
on page 9‑36.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
(Continued)
WARNING (Continued)
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
1(On/Off):Press to turn the
cruise control system on and off. An
indicator light will turn on or off in
the instrument cluster.

Driving and Operating 9-43
Each time this is done, the
vehicle goes about 1.6 km/h
(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle's speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previous set cruise control speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle's
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle's speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle's speed. When the brakes
are applied, the cruise control
shuts off. Ending Cruise Control
There are three ways to end cruise
control:
.To disengage cruise control,
step lightly on the brake pedal or
clutch; when cruise control
disengages, the indicator light
will not be lit.
.Press*on the steering wheel.
.To turn off the cruise control,
press
1on the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
1
or if the ignition is turned off.
Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Front and
Rear Parking Assist (UFRPA) or
Ultrasonic Rear Parking Assist
(URPA) system assists the driver
with parking and avoiding objects.
At speeds less than 8 km/h (5 mph),
the system detects objects up to
1.5 m (5 ft) behind the vehicle, and
at least 25 cm (10 in) off the ground.
If the vehicle has the UFRPA
system, it also detects objects 1.2 m
(4 ft) in front of the vehicle.
{WARNING
The parking assist system does
not detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at (Continued)

WARNING (Continued)
parts. The area damaged by the
tire chains could cause loss of
control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
on page 10‑41. If air goes out of a
tire, it is much more likely to leak
out slowly. But if there is ever a
blowout, here are a few tips about
what to expect and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.{WARNING
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{WARNING
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
