126 Instruments and Controls
English
This gauge indicates boost under
heavier throttle.
It displays the air pressure level in
the intake manifold before it enters
the engine's combustion chamber.
The gauge is automatically centered
at zero every time the engine is
started. Actual boost is displayed
from this zero point. Changes in
ambient pressure, such as driving in
mountains and changing weather,
will slightly change the zero reading. Engine Oil Pressure
Gauge (Base Level
Cluster Only)
Metric, Standard Theme Shown English, Standard Theme Shown
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity.
A reading outside the normal
operating range can be caused by a
dangerously low oil level or some
other problem causing low oil
pressure. Check the vehicle's oil as
soon as possible. An oil pressure

Oil Messages 0 149
and Engine Oil 0 270 .
CautionLack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil. Engine Oil Temperature
Gauge (Performance
Configuration Only)
Metric English
This gauge shows the engine oil
temperature.
If the gauge pointer moves into the
high end, it means that the engine
oil has overheated. If the vehicle
has been operated under normal
driving conditions, pull off the road,
stop the vehicle, and turn off the
engine as soon as possible.
See Engine Oil 0 270 .

a symbol when the trunk is open.
Close the trunk completely.
Engine Cooling System
Messages A/C OFF DUE TO HIGH
ENGINE TEMP This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor automatically turns off.
When the coolant temperature
returns to normal, the air
conditioning compressor turns back
on. The vehicle can continue to be
driven.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine. COOLANT LEVEL LOW ADD

engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down.
ENGINE OVERHEATED —
STOP ENGINE This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
Stop and turn off the vehicle as
soon as it is safe to do so to avoid
severe damage. This message
clears when the engine has cooled
to a safe operating temperature. HIGH COOLANT
TEMPERATURE This message may display if the
coolant temperature is hot. See
Engine Overheating 0 280 .
Engine Oil Messages CHANGE ENGINE OIL SOON This message displays when the
engine oil needs to be changed.
When you change the engine oil, be
sure to reset the oil life system. See

Driving and Operating 205CautionCranking 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 ENGINE START/
STOP. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts,
release 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
{ WarningExiting the vehicle without first
shifting into P (Park) may cause
the vehicle to move. You or others
may be injured. Because the
vehicle has the 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 to LOCK/OFF, before
exiting the vehicle.
The vehicle has a fuel saving stop/
start system to shut off the engine
and help conserve fuel. Auto Engine Stop/Start
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
0 124 . When the brake pedal is
released or the accelerator pedal is
pushed, the engine will restart.
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 between − 10 °C (14 °F)
and 50 °C (122 °F).
.
The shift lever is in any gear
other than D (Drive).
.
The battery has been recently
disconnected.
.
The battery charge is low.
.
The interior comfort level has not
reached the required level for
the climate control system or

Driving and Operating 257necessary to go much 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.
Making Turns
CautionMaking very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer will not strike soft
shoulders, curbs, road signs, trees, or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
If the trailer turn signal bulbs burn
out, the arrows on the instrument
cluster will still flash for turns. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might get hot and no longer
work well.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if
the transmission shifts too often
under heavy loads and/or hilly
conditions.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, see Engine
Overheating 0 280 .
Parking on Hills
{ WarningParking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
