Starting and Operating Your
VehicleNew Vehicle Break-InNotice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:•
Do not drive at any one constant speed, fast or
slow, for the first 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
•
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
•
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 5-28for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR AJAR
when the driver door is opened, the ignition is in
ACC/ACCESSORY or LOCK/OFF and the key is in
the ignition. SeeDIC Warnings and Messages on
page 4-44for more information.Retained Accessory Power (RAP)These vehicle accessories can be used for up to
10 minutes after the engine turned off:•
Audio System
•
Power WindowsThe radio will work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF the radio will continue to
work 10 minutes or until the driver’s door is opened.
The power windows will continue to work for up to
10 minutes or until any door is opened.
Starting the EngineMove the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when the
vehicle is stopped.
3-21

Starting Procedure1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let go of
the key. The idle speed will slow down as the engine
warms. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START, cranking will be stopped after 15 seconds to
prevent cranking motor damage. To prevent gear
damage, this system also prevents cranking if the
engine is already running. Engine cranking can be
stopped by turning the ignition switch to the ACC/
ACCESSORY or LOCK/OFF position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
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 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
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 hold the key in START
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 key and accelerator. If the vehicle starts briefly
but then stops again, repeat these steps. 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.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.
3-22

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice,
or Snow on page 5-19.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{
WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It
provides the best fuel economy. If you need more
power for passing, and you are:
•
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
The transmission will shift down to the next gear and
the vehicle will have more power.

Windshield WasherAt the top of the multifunction lever, there is a paddle
with
L
on it. Push the paddle to spray washer fluid on
the windshield. The wipers run for several sweeps and
then either stop or return to the preset speed. The ignition
key must be in ACC/ACCESSORY or ON/RUN for this to
work. SeeWindshield Washer Fluid on page 6-33.
{
WARNING:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking your
vision.
When the vehicle is low on washer fluid, the WASHER
FLUID LOW ADD FLUID displays in the Driver
Information Center (DIC) for 60 seconds. When the
ignition is turned off, this message displays again for
three seconds to remind you that the fluid level is low.
Until the fluid reservoir is refilled, every time the vehicle
is started, the WASHER FLUID LOW ADD FLUID
message displays in the Driver Information Center (DIC)
for 60 seconds. SeeDIC Warnings and Messages on
page 4-44.
Cruise ControlWith cruise control, you 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 about 40 km/h (25 mph).
{
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.
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.
If your vehicle has the Traction Control System (TCS)
and the cruise control is on, TCS will begin to limit
wheel spin and the cruise control automatically turns off.
SeeTraction Control System (TCS) on page 5-7. When
road conditions allow you to safely use it again, the cruise
control can be turned back on.

Brake System Warning LightThe vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part
can still work and stop the vehicle. For good braking
both parts need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briefly when the engine is
started. If it does not come on then, have it fixed so it
will be ready to warn if there is a problem.When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
stays on if the parking brake does not fully release. If it
stays on after the parking brake is fully released, it means
the vehicle has a brake problem.
If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push, or
the pedal can go closer to the floor. It may take longer
to stop. If the light is still on, have the vehicle towed
for service. SeeTowing Your Vehicle on page 5-26.
{
WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United States
