weight of the driver, passengers,
and cargo should never exceed the
vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/
Tire label is attached to the center
pillar (B-pillar).
The label may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. The label shows the
gross weight capacity of the
vehicle. This is called the GrossVehicle Weight Rating (GVWR).
The GVWR includes the weight of
the vehicle, all occupants, fuel,
and cargo.
The Certification/Tire label may
also show the maximum weights
for the front and rear axles, called
the Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear axles,
weigh the vehicle at a weigh
station. Your dealer can help with
this. Be sure to spread the load
equally on both sides of the
centerline.
CautionOverloading the vehicle may cause
damage. Repairs would not be
covered by the vehicle warranty. Do
not overload the vehicle.
{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.
.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.

{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 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 and shift to P (Park).
4. Set the parking brake. See Electric
Parking Brake 0238. Press ENGINE
START/STOP to turn the
vehicle off. If the vehicle cannot be pulled over
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice in 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
ENGINE START/STOP once without
the brake pedal applied will place the
ignition system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after 10 minutes
to prevent battery rundown.
ON/RUN/START (Green Indicator
Light) : This mode is for driving and
starting. With the ignition off and the
brake pedal applied, pressing ENGINE
START/STOP once will place the
ignition system in ON/RUN/START.
Once engine cranking begins, release
the button. Engine cranking will
continue until the engine starts. The

226 DRIVING AND OPERATING
Caution
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.
Caution
If you add electrical parts or
accessories, you could change the
way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty. See
Add-On Electrical Equipment0290.
To start the vehicle: 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. The idle speed
will go down as the engine warms
up. Do not race the engine
immediately 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
Remote Keyless
Entry (RKE) System Operation 07.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP 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 hold it there, then 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.
Stop/Start System
The Stop/Start system will shut off
the engine to help conserve fuel.
It has components designed for the
increased number of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.
