236 Driving and Operating
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 is equipped with
an electric power steering
system, which reduces the
amount of effort needed to
steer the vehicle. It does not
have power steering fluid.
Regular maintenance is not
required.
If the vehicle experiences a
system malfunction and loses
power steering, greater
steering effort may be
required. Power steering
assist also may be reduced if
you turn the steering wheel as
far as it can turn and hold it
there with force for an
extended period of time.
See your dealer if there is a
problem.
Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before
entering a curve.

262 Driving and Operating
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
0287.
{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.
Accessory Mode (Amber
Indicator Light) :
This mode
allows the use of some
electrical accessories when
the engine is off.
With the ignition off, pressing
the button once without the
brake pedal applied will place
the ignition system in
accessory mode.
The ignition will switch from
accessory mode to OFF after
five minutes to prevent
battery rundown.
ON/RUN/START (Green
Indicator Light) : This mode is
for driving and starting. With
the ignition off, and the brake
pedal applied, pressing the
button once will place the
ignition system in ON/RUN/
START. Once engine cranking

transmission to be manually
shifted. While in Temporary
Tap Shift Mode, the D on the
instrument cluster will be
highlighted and the current
gear shown. Automatic shifts
return after no manual shifts
have been done for seven to
10 seconds. The Temporary
Tap Shift Mode can also be
deactivated by holding the
right upshift control briefly.
While using Tap Shift, the
vehicle will have firmer, quicker
shifting. You can use this 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 you to shift into gears
appropriate for the vehicle
speed and engine revolutions
per minute (rpm). The
transmission will not
automatically shift to the next
lower gear if the engine rpm is
too high, nor to the nexthigher gear when the
maximum engine rpm is
reached.
If shifting is prevented for any
reason, a SHIFT DENIED
message will be displayed in
the instrument cluster.
Manual Mode
(Electronic Shifter)
Tap Shift
Caution
Driving 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.
If equipped, vehicles with Tap
Shift have controls on the
back of the steering wheel to
manually shift the automatic
transmission.
Permanent Tap Shift Mode
To enter Permanent Tap
Shift Mode: 1. With the vehicle in D (Drive), pull back on the
shift lever to activate
M (Manual Mode). The M in
the shift pattern will
illuminate in red, and the D
will switch to white. While
in Permanent Tap Shift

286 Driving and Operating
.When ARM is deactivated,
the gear number is white.
.If no gear number is
displayed while the shift
lever is in gear, service is
required. All rev matching
will be disabled and the
malfunction indicator lamp
will be on. See Malfunction
Indicator Lamp (Check
Engine Light)0118. The
clutch and manual
transmission will continue to
operate normally.
ARM will also:
.Be active above 28 km/h
(18 mph).
.Match engine speed up to
6100 rpm.
.Not operate when the
accelerator pedal is applied.
.Be disabled when the
coolant temperature is
below 0 °C (32 °F).
Drive Systems
All-Wheel Drive
Vehicles with this feature
always send engine power
to all four wheels. It is fully
automatic, and adjusts itself as
needed for road conditions.
Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is pressed during the tests or
when the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light
0121.
