New Vehicle Break-In
Caution
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 805 km (500 mi).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
. Avoid making hard stops for
the first 322 km (200 mi) 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

drained much sooner. And the
excessive heat can damage the
starter motor. Wait about
15 seconds between each try to
help avoid draining the battery or
damaging the starter.
2. If the engine does not start, wait about 15 seconds and try
again. Wait about 15 seconds
between each try.
When the engine has run about
10 seconds to warm up, the
vehicle is ready to be driven.
Do not run the engine at high
speed when it is cold.
If the weather is below freezing
(0 °C or 32 °F), let the engine
run for a few minutes to
warm up.

3. If the engine still will not start,or starts but then stops, 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
about three seconds. If the
vehicle starts briefly but then
stops again, do the same thing,
but this time keep the pedal
down for five or six seconds.
This clears the extra gasoline
from the engine.
Keyless Access 1. With the Keyless Access system, the RKE transmitter
must be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied. When the
engine begins cranking, let go
of the button.

after starting it. If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC)
message will display.
See
Driver Information Center
(DIC) 0109 and
Remote Keyless Entry (RKE)
System Operation (Keyless
Access) 010 or
Remote Keyless Entry (RKE)
System Operation (Key
Access) 016.
Caution
Cranking the engine for long
periods of time, by trying to start
the engine 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 ENGINE START/
STOP, 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
The engine heater can provide
easier starting and better fuel
economy during engine warm-up in
cold weather conditions at or below
−18 °C (0 °F). Vehicles with an
engine heater should be plugged in
at least four hours before starting.1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is
located in the driver side of the
engine compartment, near the
battery. It is shipped from the
factory with a tie holding it in place. Use care in removing
the tie so that the cord is not
damaged.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
(Continued)
Warning (Continued)
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make
it overheat and cause a fire,
property damage, electric
shock, and injury.
. Do not operate the vehicle
with the heater cord
permanently attached to the
vehicle. Possible heater
cord and thermostat
damage could occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never
close the hood on the
heater cord.
. Before starting the vehicle,
unplug the cord, reattach
the cover to the plug, and
securely fasten the cord.

4. Before starting the engine, besure to unplug and store the
cord as it was before to keep it
away from moving engine
parts. If you do not it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

3. Push the ignition key in, toward the steering column and then
turn the ignition off.
4. If equipped, remove the key and take it with you. If you can
leave the vehicle with the
ignition key in your hand, the
vehicle is in P (Park).
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
See Shifting Into Park 0177.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set before
you leave it. After you have moved

178 Driving and Operating
the shift lever into P (Park), hold the
brake pedal down. Then see if you
can move the shift lever away from
P (Park) without first pressing the
button on the shift lever. If you can,
it means that the shift lever was not
fully locked into P (Park).
Torque Lock
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle may put too much force on
the parking pawl in the
transmission. You may find it difficult
to pull the shift lever out of P (Park).
This is called“torque lock.”
To prevent torque lock, set the
parking brake and then shift into
P (Park) properly before you leave
the driver seat. To find out how, see
“Shifting Into Park” previously in this
section.
When you are ready to drive, move
the shift lever out of P (Park) before
you release the parking brake.
If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of the pressure from the parking pawl
in the transmission, so you can pull
the shift lever out of P (Park).
Shifting out of Park
This vehicle is equipped with a shift
lock control. The shift lock control is
designed to:
.
Prevent ignition key removal,
if equipped, unless the shift lever
is in P (Park) with the shift lever
button fully released.
. Prevent movement of the shift
lever out of P (Park) unless the
ignition is on and the brake
pedal is applied.
The shift lock control is always
functional except in the case of an
uncharged or low voltage (less than
9-volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See Jump Starting - North
America 0260. To shift out of P (Park):
1. Apply the brake pedal.
2. Turn the ignition on.
3. Press the shift lever button.
4. Move the shift lever to the desired position.
If still unable to shift out of P (Park): 1. Fully release the shift lever button.
2. Hold the brake pedal down and press the shift lever button
again.
3. Move the shift lever to the desired position.
If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
The doors may lock when shifting
from P (Park). See Automatic Door
Locks 023.

running with the RKE transmitter
inside the vehicle, it will continue to
run for up to an hour.
The vehicle could turn off sooner if it
is parked on a hill, due to lack of
available fuel.
The timer will reset if the vehicle is
taken out of P (Park) while it is
running.
Engine Exhaust
{Warning
Engine exhaust contains carbon
monoxide (CO), which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
. The vehicle idles in areas
with poor ventilation
(parking garages, tunnels,
deep snow that may block
underbody airflow or tail
pipes).
. The exhaust smells or
sounds strange or different.
. The exhaust system leaks
due to corrosion or damage.
. The vehicle exhaust system
has been modified,
damaged, or improperly
repaired.
