Loading Information label and
the Certification label.
{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
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle. Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is

starting it. Operate the engine
and transmission gently until
the oil warms up and lubricates
all moving parts.
Stop/Start System
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle may have an auto engine
stop/start 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 off before exiting the
vehicle.
The vehicle may be equipped with a
fuel saving Stop/Start system to
shut off the engine to help
conserve fuel.
Auto Stop (Vehicles without
eAssist)
If equipped, when the brakes are
applied and the vehicle is at a
complete stop, the engine may turn
off. When stopped, the tachometer
displays AUTO STOP. See
Tachometer 0112. When the brake
pedal is released or the accelerator
pedal is pushed, the engine will
restart.
The vehicle may remain in Auto
Stop even after it is shifted into
P (Park). Auto Stop will be
maintained until the door is opened
or the seat belt is unbuckled. There are several conditions that
may prevent an Auto Stop or cause
an Auto Start.
Auto Stop may be deactivated if:
.
A minimum vehicle speed is not
reached.
. The engine or transmission is
not at the required operating
temperature.
. The outside temperature is not
in the required operating range,
typically below −10 °C (14 °F) or
above 50 °C (122 °F).
. The transmission is in any gear
other than D (Drive).
. The battery charge is low.
. The battery has been
disconnected.
. The system may not be able to
shut off the engine in order to
maintain the air conditioning
comfort level or defrost system
settings. See Dual Automatic
Climate Control System 0152.
To maximize fuel economy, use
the ECO air conditioning mode.

or defrost. SeeDual Automatic
Climate Control System 0152.
. The high voltage battery charge
is low and requires recharging.
. Auto Stop time is greater than
two minutes.
. The hood is opened.
Engine Heater
The engine heater, if available, can
help in cold weather conditions at or
below −18 °C (0 °F) for easier
starting and better fuel economy
during engine warm-up. Plug in the
coolant heater at least four hours
before starting the vehicle. An
internal thermostat in the plug end
of the cord will prevent engine
heater operation at temperatures
above −18 °C (0 °F).
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is on the
driver side of the engine
compartment, between the
fender and the engine
compartment fuse block.
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.
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.
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.
