Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
.Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
.Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator andthen, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
.Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go.
The vehicle may straighten out.
Be ready for a second skid if it
occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other

Driving and Operating 9-15
If you put things inside the
vehicle—like suitcases, tools,
packages, or anything
else —they will go as fast as the
vehicle goes. If you have to stop
or turn quickly, or if there is a
crash, they will keep going.
{Warning
Things inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as
far forward as possible.
Try to spread the weight
evenly.
(Continued)
Warning (Continued)
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.
Starting and
Operating
New Vehicle Break-In
Follow these recommended
guidelines during the first
2 414 km (1,500 mi) of driving this
vehicle. Parts have a break-in
period and performance will be
better in the long run.
For the first 2 414 km (1,500 mi):
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4000 engine rpm.
.Avoid driving at any one
constant speed, fast or slow.
.Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.

9-16 Driving and Operating
.Do not let the engine labor.
Never lug the engine in high
gear at low speeds. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
.New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.
Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three modes: ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interferenceto the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation on page 2-2.
To shift out of P (Park), the vehicle
must be in ON/RUN/START and the
brake pedal must be applied.
Stopping the Engine/OFF (No
Indicator Lights):
When the
vehicle is stopped, press the
ENGINE START/STOP button 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) on page 9-21.
Automatic Transmission
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a
message in the Driver Information
Center (DIC). See Transmission
Messages on page 5-42. When the
vehicle is shifted into P (Park), the
ignition system will switch to OFF.

Driving and Operating 9-17
Manual Transmission
If the vehicle is stationary, the
ignition will turn OFF, and Retained
Accessory Power (RAP) will remain
active. SeeRetained Accessory
Power (RAP) on page 9-21.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is
switched to OFF and either front
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 to LOCK/OFF.
4. Set the parking brake. See Parking Brake (Electric) on
page 9-30 orParking Brake
(Manual) on page 9-32.{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 the ENGINE START/
STOP button for longer than
two seconds, or press twice within
five seconds.
ACC/ACCESSORY (Amber
Indicator Light): This mode allows
you to use some electrical
accessories when the engine is off.
With the ignition off, pressing the
button one time without the brake
pedal applied will place the ignition
system in ACC/ACCESSORY.

release the button. Engine cranking
will continue until the engine starts.
See Starting the Engine on
page 9-18. The ignition will then
remain in ON/RUN/START.
Service Only Mode
This power mode is available for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. With the vehicle off, and
the brake pedal not applied,
pressing and holding the button for
more than five seconds will place
the vehicle in Service Only Mode. The instruments and audio systems
will operate as they do in ON/RUN/

Starting Procedure (Keyless
Access)
1. With the Keyless Accesssystem, the RKE transmitter
must be in the vehicle. Press the
ENGINE START/STOP button
with the brake pedal applied.
When the engine begins
cranking, let go of the button.
The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or the RKE battery
is low, the Driver Information
Center (DIC) will display a
message. See Remote Keyless
Entry (RKE) System Operation
on page 2-2 andKey and Lock
Messages on page 5-36.{Caution
Cranking the engine for long
periods of time, by pressing the
ENGINE START/STOP button
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you press the ENGINE
START/STOP button, for up to a
maximum of 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool down. When the engine
starts, let go of the button and
the accelerator. If the vehicle starts briefly but then stops
again, do the same thing. This
clears the extra gasoline from
the engine. Do not race the
engine immediately after starting
it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Engine Heater
Vehicles with the engine coolant
heater can use this option in cold
weather conditions at or below
−18°C (0°F) for easier starting and
better fuel economy during engine
warm-up. Plug in the coolant heater
at least four hours before starting
your vehicle. An internal thermostat
in the plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above
−18°C (0°F).
