Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop the vehicle and turn off the
engine to avoid damage to the
engine. A warning chime sounds
when this light is on.
SeeEngine Overheating
on
page 10‑24for more information.
Tire Pressure Light
For vehicles with a Tire Pressure
Monitor System, this light comes on
briefly when the engine is started.
It provides information about tire
pressures and the Tire Pressure
Monitor System.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A tire pressure message can
accompany the light. See Tire
Messages
on page 5‑43for more
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information Label. See
Tire Pressure
on page 10‑74for
more information. When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See
Tire Pressure Monitor
Operation
on page 10‑77for more
information.

Engine Cooling System
Messages
Engine Hot A/C (Air
Conditioning) Off
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
SeeEngine Coolant Temperature
Gauge
on page 5‑16. 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. You can
continue to drive the vehicle.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.
Engine Overheated Idle Engine
Notice: If you drive your vehicle
while the engine is overheating,
severe engine damage may
occur. If an overheat warning
appears on the instrument panel
cluster and/or DIC, stop the
vehicle as soon as possible. Do
not increase the engine speed
above normal idling speed. See
Engine Overheating
on page 10‑24for more information.
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down. If the
message does not clear in a
few minutes or if the overheat light
stays on, shut the vehicle off and
have it serviced before driving
again. See Engine Coolant
Temperature Warning Light
on
page 5‑25.
See Overheated Engine Protection
Operating Mode
on page 10‑25for
information on driving to a safe
place in an emergency.
Engine Oil Messages
Change Engine Oil Soon
When this message displays, it
means that service is required for
the vehicle. See your dealer. See
Scheduled Maintenance
on
page 11‑3and Engine Oilon
page 10‑11for more information.
When you reset the Change Engine
Oil Soon message by clearing it
from the display, you still must reset
the engine oil life system separately.
For more information on resetting
the engine oil life system, see
Engine Oil Life System

Lighting 6-7
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 the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, 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 Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE or BATTERY
VOLTS LOW. If this message is
displayed, it is recommended that
the driver reduce the electrical loads
as much as possible. See
Driver
Information Center (DIC)
on
page 5‑27.
Battery Power Protection
This feature helps to prevent battery
drain if accessory lamps are left on.
If accessory lamps such as the
vanity mirror, cargo, reading,
console, or glove box are left on,
they automatically time-out after
about 20 minutes. To reset the
battery protection, all of the above
lamps must be turned off or the
ignition must be in the ACC/
ACCESSORY position.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned to LOCK/OFF, if the parking
lamps or headlamps have been left
on. This protects against draining
the battery. The battery saver does
not work if the headlamps are
turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than
10 minutes, turn the lamps back on
with the exterior lamp control.

9-8 Driving and Operating
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When your vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTireson
page 10‑66.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park your vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Black plate (55,1)Cadillac CTS/CTS-V Owner Manual - 2011
Driving and Operating 9-55
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, seeEngine Overheating
on page 10‑24.
Parking on Hills
{WARNING
Parking 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 for
vehicles with an automatic
transmission, or into gear for
vehicles with a manual transmission. Turn the wheels
into the curb if facing downhill or
into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park) for vehicles with an
automatic transmission or into
gear for vehicles with a manual
transmission.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.Start the engine,
.Shift into a gear, and
.Release the parking brake.
2. Let up on the brake pedal. 3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual's Maintenance Schedule or
Index for more information. Things
that are especially important in
trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. It is a good idea to
inspect these before and during
the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
