SLIDING DOOR – FREQUENTLY
ASKED QUESTIONS
Why does the power sliding door stop
moving?
The power sliding door stops when it
detects an obstacle. A tone sounds
and the power sliding door starts
moving in the opposite direction. After
you remove the obstacle, you can
continue to operate the power sliding
door.
Why is the power sliding door moving
with reduced speed? You let the power sliding door open
for more than five minutes. Fully close
the power sliding door using the button
on the instrument panel or the power
sliding door handles. Open the power
sliding door as normal.
Why can I not close the power sliding
door? If the power sliding door does not
close, restart the engine and then
close it as normal. See Closing the
Sliding Door From Inside Your
Vehicle (page 83). If the power sliding
door still does not close, manually
close the power sliding door and then
open it as normal. If the power sliding
door still does not close the system
has malfunctioned. Have your vehicle
checked as soon as possible.
What can I do if the power sliding door
does not operate as normal? If there is a malfunction on the power
sliding door, restart the engine. How can I open the sliding door if the
system loses power?
If the sliding door loses power, you
could need to apply more force when
trying to open it. Push the back of the
sliding door and the interior sliding
door handle in opening direction at the
same time and open it as normal.

You can only attempt to start the
engine for a limited amount of time before
the starting system temporarily disables. If
you exceed the starting time limit, a
message may appear and you cannot
attempt to start the engine for at least 15
minutes.
Before starting your vehicle, check the
following:
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
Starting the Engine
1. Fully press the brake pedal.
Note: Do not touch the accelerator pedal.
2. Turn the key to position III.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: The engine takes longer to start at
lower temperatures. It may crank for several
seconds when very cold.
Failure to Start
If you cannot start the engine after 3
attempts, wait 10 seconds and do the
following:
1. Fully press the brake pedal.
2. Apply the parking brake.
3. Shift into park (P).
4. Fully press the accelerator pedal and hold it there.
5. Turn the key to position
III and wait
until the engine stops cranking.
6. Release the accelerator pedal.
7. Start the engine. Stopping the Engine When Your

2. Turn the key to position
0.
3. Apply the parking brake.
Stopping the Engine When Your
Vehicle is Moving WARNING:
Switching off the
engine when your vehicle is still moving
results in a significant decrease in
braking assistance. Higher effort is
required to apply the brakes and to stop
your vehicle. A significant decrease in
steering assistance could also occur. The
steering does not lock, but higher effort
could be required to steer your vehicle.
When you switch the ignition off, some
electrical circuits, for example airbags,
also turn off. If you unintentionally switch
the ignition off, shift into neutral (N) and
restart the engine.
1. Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. Shift into park (P).
3. Turn the key to position
0.
4. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.

Engine Warning Lamps Malfunction Indicator Lamp
Check Engine
If it illuminates when the engine is running
this indicates a malfunction. The On Board
Diagnostics system has detected a
malfunction of the vehicle emission control
system.
If it flashes, engine misfire may be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Avoid heavy acceleration and deceleration
and have your vehicle immediately
serviced. Powertrain Warning Lamp
If it illuminates when the engine is running
this indicates a malfunction. If it flashes
when you are driving, immediately reduce
the vehicle speed. Avoid heavy
acceleration and deceleration and have
your vehicle immediately serviced.
If both lamps illuminate when the engine
is running, stop your vehicle as soon as it
is safe to do so. Continuing to drive your
vehicle may cause reduced power or the
engine to stop. Switch the ignition off and
attempt to restart the engine. Have your
vehicle immediately checked. SWITCHING OFF THE ENGINE
Vehicles With a Turbocharger WARNING: Do not switch the
engine off when it is running at high
speed. If you do, the turbocharger will
continue running after the engine oil
pressure has dropped to zero. This will
lead to premature turbocharger bearing
wear.
Release the accelerator pedal. Wait until
the engine has reached idle speed and then
switch it off.
ENGINE BLOCK HEATER
(IF
EQUIPPED) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
Note: The heater is most effective when
outdoor temperatures are below
0°F
(-18°C).
