Driving and Operating 9-27
Vehicle speeds above
110 km/h (68 mph) should
be limited to five minutes
per use.
.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
breaking-in guideline every
time you get new brake
linings.
.Do not tow a trailer during
break-in. SeeDriving
Characteristics and Towing
Tips on page 9‑58 for the
trailer towing capabilities
of your vehicle and more
information.
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 9‑30.
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.

9-28 Driving and Operating
In an emergency, if the vehicle must
be shut off while driving:
1. Brake using a firm and steadypressure. 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), and turn the ignition
to LOCK/OFF. On vehicles with
an automatic transmission, the
shift lever must be in P (Park) to
turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake on page 9‑38.{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.
5. If the vehicle must be shut off while driving, turn the ignition to
ACC/ACCESSORY.
The ignition switch can bind in the
LOCK/OFF position with the wheels
turned off center. If this happens,
move the steering wheel from
right to left while turning the key
to ACC/ACCESSORY. If this does
not work, then the vehicle needs
service.
B (ACC/ACCESSORY): This
position provides power to some
of the electrical accessories.
It unlocks the steering wheel and
ignition. To move the key from ACC/ACCESSORY to LOCK/OFF,
push in the key and then turn it to
LOCK/OFF.
C (ON/RUN):
The ignition switch
stays in this position when the
engine is running. This position
can be used to operate the
electrical accessories, including the
ventilation fan and 12‐volt power
outlets, as well as to display some
warning and indicator lights. The
transmission is also unlocked in this
position on automatic transmission
vehicles.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
D (START): This position starts
the engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.

Driving and Operating 9-29
A warning tone sounds when the
driver door is opened if the ignition
is still in ACC/ACCESSORY and the
key is in the ignition.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
vehicle when it 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.
Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go 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 for many seconds,
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 ACC/ACCESSORY or
LOCK/OFF.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 to 10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Push the
accelerator pedal all the way to
the floor and hold it there as you
hold the key in START for a
maximum of 15 seconds. Wait at
least 15 seconds between each
try, to allow the cranking motor
to cool. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, repeat the
procedure. This clears the
extra gasoline from the engine.

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground.
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.Objects that are below the
bumper, underneath the
vehicle, or too close or far
from the vehicle.
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing, vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is
continuous for 5 seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below taillamp level. Objects must
also be within 2.5 m (8 ft) from the
rear bumper. The distance objects
can be detected may be less during
warmer or humid weather.

9-46 Driving and Operating
PARK ASSIST OFF displays on the
Driver Information Center (DIC) to
indicate that URPA is off. The
message disappears after a short
period of time.
SeeObject Detection System
Messages on page 5‑27 for URPA
messages.
Turning the System On and Off
The URPA system can be turned
on and off using the infotainment
system controls. See Vehicle
Personalization on page 5‑30 for
more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays on the DIC.
See Driver Information Center (DIC)
on page 5‑20 for more information.
This can occur under the following
conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑82.
.The park assist sensors are
covered by frost or ice, which
can occur after washing the
vehicle in cold weather. Keep
the sensors free of frost or ice.
.A trailer was attached to the
vehicle, or an object was
hanging out of the trunk during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
.The vehicle's bumper is
damaged. Take the vehicle to
your dealer to repair the system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.

.Do not use the Fuel Saver Mode
when towing.
.Obey speed limit restrictions.
Do not drive faster than the
maximum posted speed for
trailers, or no more than 90 km/h
(55 mph), to reduce wear on the
vehicle.
.For vehicles with the Ultra
Rear Parking Assist (URPA)
system, turn the system off when
towing a trailer. If the tow bar
is installed while not towing a
trailer, change the URPA system
to the“Tow Bar” setting. See
Ultrasonic Parking Assist on
page 9‑45 for more information.
Driving with a Trailer
Towing a trailer requires experience.
Get familiar with handling and
braking with the added trailer
weight. The vehicle is now longer
and not as responsive as the
vehicle is by itself. Check all trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps, tires
and mirror adjustments. If the trailer
has electric brakes, start the vehicle
and trailer moving and then apply
the trailer brake controller by hand
to be sure the brakes are working.
During the trip, check regularly to be
sure that the load is secure, and the
lamps and trailer brakes are working
properly.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move that hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.

Vehicle Care 10-21
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL coolant mixture to
the coolant surge tank until
the level reaches the COLD
FILL line.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight.
Check the level in the coolant
surge tank when the cooling system
has cooled down. If the coolant
is not at the proper level, repeat
Steps 1 through 3 and reinstall the
pressure cap. If the coolant still is
not at the proper level when the
system cools down again, see your
dealer.Engine Overheating
The vehicle has an indicator to warn
of engine overheating. There is an
engine coolant temperature warning
light on the vehicle's instrument
panel. See Engine Coolant
Temperature Gauge on page 5‑10.
The decision may be made not
to lift the hood when this warning
appears, but instead get service
help right away. See Roadside
Assistance Program (U.S. and
Canada) on page 13‑7 orRoadside
Assistance Program (Mexico) on
page 13‑9. If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan(s) are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Engine damage from
running the engine without
coolant is not covered by the
warranty.
