WARNING: Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See
Locating
the Fuel Filler Funnel (page 260).
Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.
When refueling the vehicle fuel tank from
a fuel container, do the following:
1. Fully open the fuel filler door. 2.
Fully insert the fuel filler funnel into the
fuel filler inlet.
3. Add fuel to your vehicle from the fuel container.
4. Remove the fuel filler funnel.
5. Fully close the fuel filler door.
6. Clean the fuel filler funnel and place it back in your vehicle or correctly dispose
of it. Note:
If your vehicle runs out of fuel add a
minimum of
1.3 gal (5 L) of fuel to restart
the engine.
Note: You may need to switch the ignition
from off to on several times after refueling
to allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note: Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.

Failure to perform active or manual
regeneration when instructed could result
in a clogged diesel particulate filter. If the
diesel particulate filter fills beyond the
regeneration threshold, your vehicle
disables the ability for active and manual
regeneration. This could result in
irreversible damage your vehicle Warranty
may not cover.
DIESEL PARTICULATE FILTER
REQUIREMENTS
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function.
If your journeys meet one of the following
conditions:
•
You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and observe
speed limits and road conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM. DIESEL PARTICULATE FILTER

temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. 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.
To avoid damaging the catalytic converter:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 486). •
Use the correct fuel.
See Fuel and
Refueling (page 255).
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.

BRAKES –
TROUBLESHOOTING
BRAKES – WARNING LAMPS
If the ABS indicator illuminates
when you are driving, this
indicates a malfunction. Your
vehicle continues to have normal braking
without the anti-lock braking system
function. See an authorized dealer.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to

brake is disengaged. If the parking brake
is disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer.
BRAKES – FREQUENTLY ASKED
QUESTIONS
Is it normal for my brakes to make
noise?
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding,
or continuous squeal sound is present,
the brake lining could be worn-out.
Have the system checked by an
authorized dealer. There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is this
normal?
Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.
Note: Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is normal as the
brakes wear and does not contribute to
brake noise. See Cleaning Wheels (page
535).

WHAT IS TRACTION CONTROL
The traction control system helps to avoid
drive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss of
traction can compromise steering control
and stability of the vehicle. The traction
control system applies the brakes to
individual wheels and when needed,
reduces engine power at the same time to
increase traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. The traction control system turns on each
time you switch the ignition on.
The button for the stability and traction
control system is on the instrument panel. Press and release the button to switch
traction control off. The stability control
system remains fully active, to switch it off,
press and hold the button for a few
seconds, then release.
When you switch traction control off, a
message and an illuminated icon appear
on the instrument cluster.
Press the switch again to turn the traction
control system back on to normal
operation.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Your vehicle may have MyKey restrictions
regarding this feature. See
What Is
MyKey (page 98).
TRACTION CONTROL
INDICATOR
Stability and Traction Control
Indicator If the indicator does not
illuminate when you switch the
ignition on, or remains on when
the engine is running, this indicates a

by an authorized dealer as soon as
possible. The traction control off indicator
illuminates when you switch the
traction control system off, or
when an alternative stability control mode
is selected that requires the traction
control off depending on the drive mode
selected.
