5-24 Instruments and Controls
The instantaneous fuel economy
reflects only the current fuel
economy and changes frequently as
driving conditions change. Unlike
average economy, this display
cannot be reset.
Average Vehicle Speed
This display shows the average
speed of the vehicle in kilometers
per hour (km/h) or miles per
hour (mph). This average is
calculated based on the various
vehicle speeds recorded since the
last reset of this value. The average
speed can be reset by pressing
SET/CLR while the Average Vehicle
Speed display is showing.
Timer
This display can be used as a timer.
To start the timer, press SET/CLR
while Timer is displayed. The
display will show the amount of time
that has passed since the timer was
last reset, not including time theignition is off. Time will continue to
be counted as long as the ignition is
on, even if another display is being
shown on the DIC. The timer will
record up to 99 hours, 59 minutes,
and 59 seconds (99:59:59) after
which the display will return to zero.
To stop the timer, press SET/CLR
briefly while Timer is displayed.
To reset the timer to zero, press and
hold SET/CLR.
Digital Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset.

Navigation System Turn-by-Turn
guidance. See the Navigation

Driving and Operating 9-17
Following break‐in, engine speed
and load can be gradually
increased.
Ignition Positions
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.
A (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 9‑21 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.
In an emergency, if the vehicle must
be shut off while driving:
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.

Driving and Operating 9-31
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
the driver 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 tooclose 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 the driver 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.
