2008 CADILLAC CTS hood release

If the vehicle is left running it automatically shuts off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the remote
start button is pressed and held again before the rst
10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of
the engine run time, 10 minutes are added and you
now have 15 minutes of engine running. The added
ten minutes are considered a second remote vehicle
start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the keyless access ignition control knob before
the remote start feature can be used again.The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled.
See “Remote Start” underDIC Vehicle
Customization on page 3-69.
The engine turns off during a remote vehicle start if the

the dust and pollen from the air entering the vehicle.

air lter installed could let water or other debris enter
the system. This could cause a water leak or noises.

old one.
The passenger compartment air lter is located
underneath the hood below the windshield wiper arm
and the screen on the passenger side of the vehicle.

for more information on location.To replace the passenger compartment air lter:
1. Turn the ignition to ON/RUN with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are straight up on
the windshield.
This allows access to the leaf screen.
The passenger compartment air lter is
located under the screen.
3. Open the hood to access the engine compartment.
SeeHood Release on page 5-12for more
information.
4. Remove the three screws that hold the screen in
place and lift off the screen by lifting and sliding it
toward the center of the vehicle.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may
be necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to
be re-aimed. It is possible however, to re-aim the
headlamps as described.
The vehicle should:
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
Have all four tires on a level surface which is level
all the way to the wall.
Be placed so it is perpendicular to the wall.
Not have any snow, ice, or mud on it.
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
Normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
Have all tires properly inated.
If your vehicle has a spare tire, ensure the spare tire
is in its original location in the vehicle.
Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. SeeHood Release on page 5-12
for more information.
