9-62 Driving and Operating
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 have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils 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 could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑14.
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. 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).
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.
.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 the
Maintenance Schedule on
page 11‑3. Things that are
especially important in trailer
operation are automatic
Black plate (63,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Driving and Operating 9-63
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 10‑14.
Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
.The weight of the trailer.
.The weight of the trailer tongue.
.The total weight on your
vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
454 kg (1,000 lbs). But even that
can be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature, and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue”
later in this section.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers, and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight. Ask your dealer for trailering
information or advice, or write us at
our Customer Assistance Offices.
See
Customer Assistance Offices
on page 13‑3.
Weight of the Trailer Tongue
The tongue load (1) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.
If there are a lot of options,
equipment, passengers, or cargo in
the vehicle, it will reduce the tongue
weight the vehicle can carry, which
will also reduce the trailer weight the
vehicle can tow. If towing a trailer,
the tongue load must be added to
the GVW because the vehicle will
be carrying that weight, too. See
Vehicle Load Limits on page 9‑10.
Black plate (64,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
9-64 Driving and Operating
The trailer tongue (1) should weigh
10 to 15 percent of the total loaded
trailer weight (2).
After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some
items around in the trailer.
Total Weight on Your Vehicle's
Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be foundon the Tire and Loading Information
label. See
Vehicle Load Limits on
page 9‑10. Make sure not to go over
the GVW limit for the vehicle,
including the weight of the trailer
tongue.
Towing Equipment
Hitches
Use the correct hitch equipment.
See your dealer or a hitch dealer for
assistance.
.The rear bumper on the vehicle
is not intended for hitches. Do
not attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
.Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If so,
seal the holes when the hitch is
removed. If the holes are not
sealed, dirt, water, and deadly
carbon monoxide (CO) from the exhaust can get into the vehicle.
See
Engine Exhaust on
page 9‑21.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Leave enough slack so the rig can
turn. Never allow safety chains to
drag on the ground.
Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well,
or at all.

10-16 Vehicle Care
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency
situation. If an overheated engine
condition exists, an overheat
protection mode, which alternates
firing groups of cylinders, helps
prevent engine damage. In this
mode, there is significant loss in
power and engine performance. The engine coolant temperature
warning light comes on in the
instrument cluster, to indicate the
vehicle has entered overheated
engine protection operating mode.
The temperature gauge also
indicates an overheat condition
exists. Driving extended distances
and/or towing a trailer in the
overheat protection mode should be
avoided.
Power Steering Fluid
The power steering fluid reservoir is
located under the engine cover on
the passenger side toward the rear
of the engine compartment. See
Engine Compartment Overview on
page 10‑5.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
you suspect there is a leak in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
Check the level after the vehicle has
been driven for at least 20 minutes
so the fluid is warm.
To check the power steering fluid:
1. Set the ignition to OFF and let
the engine compartment
cool down.
2. Remove the engine cover. Refer toEngine Cover on page 10‑6.
3. Wipe the cap and the top of the reservoir clean.
4. Turn the cap counterclockwise and pull it straight up.

Towing the Vehicle
Notice: Incorrectly towing a
disabled vehicle may cause
damage. The damage would not
be covered by the vehicle
warranty.
Have the vehicle towed on a wheel
lift tow truck. A flatbed car carrier
could damage the vehicle. The
wheel lift tow truck must raise the
rear of the vehicle and wheel dollies
must be used to lift the front wheels
off the ground.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing” in this
section.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle such as a motor home. The
two most common types of
recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly.
Here are some important things to
consider before recreational vehicle
towing:
.What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations.
.What is the distance that will be
traveled? Some vehicles have
restrictions on how far and how
long they can tow.
Black plate (75,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Vehicle Care 10-75
.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Dinghy Towing
Notice:If the vehicle is towed
with all four wheels on the
ground, the drivetrain components could be damaged.
The repairs would not be covered
by the vehicle warranty. Do not
tow the vehicle with all four
wheels on the ground.
The vehicle was not designed to be
towed with all four wheels on the
ground. If the vehicle must be
towed, a dolly should be used. See
the following information on dolly
towing.
Dolly Towing from the Front
(Front-Wheel Drive)
Vehicles with front-wheel drive can
be dolly towed from the front.
Use the following procedure to dolly
tow the vehicle from the front:
1. Attach the dolly to the tow
vehicle following the dolly
manufacturer instructions.
2. Drive the front wheels onto the dolly.
3. Shift the transmission to P (Park).
4. Firmly set the parking brake.
5. Use an adequate clamping device designed for towing to
ensure that the front wheels are
locked into the straight-ahead
position.
6. Secure the vehicle to the dolly following the manufacturer
instructions.
7. Release the parking brake only after the vehicle being towed is
firmly attached to the towing
vehicle.
8. Turn the ignition to OFF.
