engine speed or load varies. This is
normal. If the oil pressure warning
light or DIC message indicates oil
pressure outside the normal
operating range, check the vehicle's
oil as soon as possible.
Coolant Temperature :Displays
the coolant temperature in degrees
Celsius (°C) or degrees Fahrenheit
(°F).
Diesel Exhaust Fluid (DEF) Level
Percent (Diesel Engine Only) :
If equipped, the DEF level will be
displayed as either OK, XX%,
or LOW. When LOW appears on the
display, add DEF as soon as
possible. See Diesel Exhaust Fluid
0 208.
Diesel Exhaust Fluid (DEF) Level
Gauge (Diesel Engine Only) :
If equipped, the DEF level displays
as a horizontal bar gauge with E or
0 and F or 1 at both ends. If more of
the bar is filled green, the vehicle
has a higher level of DEF. When the
estimated level is low, the gauge will
turn red and LOW will display above
the bar. When there is an error, the
bar will be empty and “unavailable”will appear. When LOW appears on
the display, add DEF as soon as
possible. See
Diesel Exhaust Fluid
0 208.
Diesel Exhaust Fluid (DEF) Range
(Diesel Engine Only) : If equipped,
this page displays how far the
vehicle can go before DEF needs to
be replaced. Range is displayed in
mi or km. When the estimated range
is low, LOW will display. If an error
occurs, “−−”will display. When DEF
range is high, a greater than sign is
shown before the range value.
When LOW appears on the display,
add DEF as soon as possible. See
Diesel Exhaust Fluid 0208.Vehicle Messages

Engine Power Messages
ENGINE POWER IS REDUCED
This message displays when the
vehicle's propulsion power is
reduced. A reduction in propulsion
power can affect the vehicle's ability
to accelerate. If this message is on,
but there is no observed reduction
in performance, proceed to your
destination. The performance may be reduced the next time the vehicle
is driven. The vehicle may be driven
while this message is on, but
maximum acceleration and speed
may be reduced. Anytime this
message stays on, or displays
repeatedly, the vehicle should be
taken to your dealer for service as
soon as possible.
Vehicle Speed Messages
SPEED LIMITED TO XXX
KM/H (MPH)
This message shows that the
vehicle speed has been limited to
the speed displayed. The limited

When the DRL are on, the taillamps,
sidemarker lamps, instrument panel
lights, and other lamps will not be
on. The instrument cluster will be lit.
The DRL turn off when the
headlamps are turned to
Oor the
ignition is off. For vehicles first sold
in Canada, the DRL can only be
turned off when the vehicle is
parked.
The regular headlamp system
should be turned on when needed.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor; otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
O

The exterior lamps turn off
immediately by turning the exterior
lamp control off.
This feature can be changed. See
Vehicle Personalization0152.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed. The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,this action may be noticeable to the
driver. If so, a DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible.
Battery Power Protection
This feature shuts off the interior
lamps if they are left on for more
than 10 minutes when the ignition is
off. This helps to prevent the battery
from running down.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

Driving Information
Driver Behavior
Driving is an important
responsibility. Driver behavior, the
driving environment, and the
vehicle's design all affect how well a
vehicle performs.
Being aware of these factors can
help in understanding how the
vehicle handles and what can be
done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced
or prevented by the use of seat
belts. In a rollover crash, an
unbelted person is significantly
more likely to die than a person
wearing a seat belt. In addition,
avoiding excessive speed, sudden
or abrupt turns, and drunken or
aggressive driving can help make
trips safer and avoid the possibility
of a crash.

182 Driving and Operating
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. If the
engine stops, there will be some
power brake assist but it will be
used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the
brake pedal will be harder to push.
Steering
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See your dealer if there is a
problem.
Curve Tips
.
Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking. .
Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
