Example 3
1.Vehicle Capacity Weight
for Example 3 = 453 kg
(1,000 lbs).
2.Subtract Occupant Weight
@ 91 kg (200 lbs) × 5 =
453 kg (1,000 lbs).
3.Available Cargo Weight =
0 kg (0 lbs).
Refer to the vehicle's Tire and
Loading Information label for
specific information about the
vehicle's capacity weight and seating positions. The combined
weight of the driver, passengers,
and cargo should never exceed
the vehicle's capacity weight.
Certification Label
Label Example
A vehicle-specific Certification
label is attached to the vehicle's
center pillar (B-pillar). The label
tells the gross weight capacity of
the vehicle, called the Gross
Vehicle Weight Rating (GVWR).
The GVWR includes the weight
of the vehicle, all occupants,fuel, and cargo. Never exceed
the GVWR for the vehicle, or the
Gross Axle Weight Rating
(GAWR) for either the front or
rear axle.
And, if there is a heavy load, it
should be spread out. See
“Steps for Determining Correct
Load Limit”
earlier in this
section.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
shorten the life of the vehicle.

9-14 Driving and Operating
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
{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 (Continued)

9-16 Driving and Operating
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 9-31.
{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,
turn the ignition to ACC/
ACCESSORY.
2 (ACC/ACCESSORY): This
position provides power to some of
the electrical accessories. It unlocks
the ignition. To move the key from
ACC/ACCESSORY to LOCK/OFF,
the shift lever must be in P (Park). 3 (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
outlet, as well as to display some
warning and indicator lights. This
position can also be used for
service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. The transmission is also
unlocked in this position.
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 restart if
the battery is allowed to drain for an
extended period of time.
4 (START): This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving. A warning tone sounds when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition. If the
ignition becomes difficult to turn,
see
Keys on page 2-1.
Ignition Positions
(Keyless Access)
The vehicle has an electronic
keyless ignition with pushbutton
start.

Driving and Operating 9-17
Pressing the button cycles it through
three modes, ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The 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
interference to the keyless access
system. SeeRemote Keyless Entry
(RKE) System Operation on
page 2-3.
To shift out of P (Park), the vehicle
must be in ACC/ACCESSORY or
ON/RUN 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 9-23. If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See
Transmission Messages on
page 5-44. When the vehicle is
shifted into P (Park), the ignition
system will switch to OFF.
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), and turn the ignition
to OFF. On vehicles with an
automatic transmission, the shift
lever must be in P (Park) to turn
the ignition switch to the OFF
position.
4. Set the parking brake. See Parking Brake on page 9-31.
{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 in
five seconds.

9-20 Driving and Operating
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. SeeKey and Lock
Messages on page 5-39 and
Remote Keyless Entry (RKE)
System Operation on page 2-3.
{Caution
Cranking the engine for long
periods of time, by returning the
ignition 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 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.
eAssist Automatic Engine
Start/Stop
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
(Continued)
Warning (Continued)
may be injured. Because the
vehicle has the automatic engine
start/stop feature, the vehicle's
engine might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn off when the brakes
are applied and the vehicle comes
to a complete stop. The vehicle may
remain in auto stop for up to
two minutes. When the brake is
released or the accelerator pedal
applied, the engine will start. The
engine will continue to run until the
next auto stop.

Failure to use the
recommended extension cord
in good operating condition,
or using a damaged heater or
extension cord, could make it(Continued)
Warning (Continued)
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

securely fasten the cord.
Keep the cord away from any
moving parts. 4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
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.

2. Move the shift lever into P (Park) by pushing the lever all the way
toward the front of the vehicle.
3. Turn the ignition off.
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. (Continued)
Warning (Continued)
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).
SeeShifting Into Park on
page 9-24. If you are towing a
trailer, see Driving Characteristics
and Towing Tips on page 9-63.
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
the shift lever into P (Park), hold down the regular brake pedal. See if
you can move the shift lever away
from P (Park) without first pulling it
toward you. If you can, it means that
the shift lever was not fully locked
into P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the
transmission. This happens when
parking on a hill and shifting the
transmission into P (Park) is not
done properly and then it is difficult
to shift out of P (Park). To prevent
torque lock, set the parking brake
and then shift into P (Park). To find
out how, see "Shifting Into P (Park)"
listed previously.
If torque lock does occur, your
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park).

If you are towing a trailer and
parking on a hill, seeDriving
Characteristics and Towing Tips on
page 9-63.
Shifting out of Park
Automatic Transmission
Shift Lock
The vehicle has an automatic
transmission shift lock control
system. The shift lock control
system is designed to:
.Prevent ignition key removal
unless the shift lever is in
P (Park).
.Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN and the
brake pedal is applied.
The shift lock 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
(On-board with eAssist Only) on
page 10-78 orJump Starting (with
or without eAssist) on page 10-79.
If the shift lever cannot be moved
out of P (Park):
1. Apply and maintain the regular brakes.
2. Turn the ignition to the ON/RUN position. See Ignition Positions
(Key Access) on page 9-15 or
Ignition Positions (Keyless
Access) on page 9-16 for more
information.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button.
5. Move the shift lever into the desired gear. If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
