2007 CADILLAC SRX tow

Checking Coolant
The coolant surge tank and pressure cap are
located on the driver’s side of the vehicle, toward
the rear of the engine compartment. See
Engine Compartment Overview on page 356for
more information on location.
{CAUTION:
Turning the surge tank pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. Never turn the surge
tank pressure cap — even a little — when
the engine and radiator are hot.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be at
the FULL COLD/FROID line on the side of the
surge tank. Follow the arrow from the top of
the tank down the side to the horizontal mark.

If No Steam Is Coming From Your
Engine
An overheat warning, can indicate a serious
problem.
If you get an engine overheat warning but see or
hear no steam, the problem might not be too
serious. Sometimes the engine can get a little too
hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is safe to
do so, pull off the road, shift to PARK (P)
or NEUTRAL (N) and let the engine idle.
2. Set the climate controls to the highest heat
setting and fan speed and open the windows,
as necessary.If the coolant warning light is not on or the coolant
temperature gage does not indicate the engine
is overheating, you can drive. Just to be safe, drive
slower for about 10 minutes. If the warnings do
not come back on, drive normally.
If the warnings continue and you have not stopped,
pull over, stop, and park the vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while parked. If the warnings are
still indicated, turn off the engine and get everyone
out of the vehicle until it cools down. Also, see
“Overheated Engine Protection Operating Mode”
later in this section.
You might decide not to lift the hood but to get
service help right away.

Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be
driven to a safe place in an emergency. Should an
hot engine condition exist, an overheat protection
mode which alternates ring groups of cylinders
helps prevent engine damage. In this mode, there is
a loss in power and engine performance. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss and change the oil. SeeEngine Oil on
page 360.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Electric Engine Cooling Fans
B. Coolant Surge Tank and Pressure Cap
Some vehicles may be equipped with an
engine driven fan, as well as the electric
pusher fans (A) which are located behind the
vehicle’s grille.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 471.
When rotating P255/50R20 size tires, always use
the correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
Tire and Loading Information label.Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the TPMS
sensors reset after a tire rotation, seeTire
Pressure Monitor System on page 410.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 464.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 424.

Notice:If your vehicle has a tire size other
than P255/50R20 use tire chains only where
legal and only when you must. Use chains that
are the proper size for your tires. Install
them on the tires of the rear axle. Do not use
chains on the tires of the front axle. Tighten
them as tightly as possible with the ends
securely fastened. Drive slowly and follow the
chain manufacturer’s instructions. If you
can hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Driving
too fast or spinning the wheels with chains on
will damage your vehicle.If a Tire Goes Flat
It is unusual for a tire to blowout while you are
driving, especially if you maintain your vehicle’s
tires properly. If air goes out of a tire, it is
much more likely to leak out slowly. But if you
should ever have a blowout, here are a few tips
about what to expect and what to do:
If a front tire fails, the at tire will create a drag
that pulls the vehicle toward that side. Take your
foot off the accelerator pedal and grip the
steering wheel rmly. Steer to maintain lane
position, and then gently brake to a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much
like a skid and may require the same correction
you would use in a skid. In any rear blowout
remove your foot from the accelerator pedal. Get
the vehicle under control by steering the way
you want the vehicle to go. It may be very bumpy
and noisy, but you can still steer. Gently brake
to a stop, well off the road if possible.
423

{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after time. The
wheel could come off and cause an
accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In
an emergency, you can use a cloth or a
paper towel to do this; but be sure to use
a scraper or wire brush later, if needed, to
get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose.
Your wheel could fall off, causing a
serious accident.
10. Install the spare tire.
11. Put the wheel nuts back on with the rounded
end of the nuts toward the wheel.
12. Tighten each nut by hand until the wheel is
held against the hub.
433

Secondary Latch System
Your vehicle has an underbody mounted tire hoist
assembly equipped with a secondary latch
system. It is designed to stop the compact spare
tire from suddenly falling off your vehicle if the
cable holding the spare tire is damaged. For the
secondary latch to work, the tire must be
stowed with the valve stem pointing down. See
Storing a Flat or Spare Tire and Tools on page 439
for instructions on storing the spare tire correctly.
{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack. If
the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.
436

To store the spare tire and tools, do the following:
1. Lay the compact spare tire on the ground
at the rear of the vehicle. Position the
compact spare tire so that the valve stem is
pointed down facing the rear of the vehicle.
2. Lower the cable to the ground. SeeRemoving
the Spare Tire and Tools on page 426.3. Tilt the retainer downward and slip it through
the center hole of the spare tire.
Make sure the retainer is fully seated across
the underside of the wheel.
4. Attach the wheel wrench to the hoist shaft.
5. Turn the wheel wrench clockwise to lift
the spare tire.
6. When the tire is almost in the stored position,
turn the tire so that the valve stem is towards
the rear of the vehicle.
This will help when you check and maintain
tire pressure in the spare.
7. Raise the tire fully against the underside of
the vehicle. Continue turning the wheel
wrench until you feel more than two clicks.
This indicates that the compact spare
tire is secure and the cable is tight. The spare
tire hoist cannot be overtightened.
