WARNING INDICATORS

Warning indicators are arranged within
the instrument panel.

There are two warning indicators, one red,
the other amber, located above the
message centre for primary and
secondary status of the warnings
displayed by the message centre.

RED warning indicators are for primary
warnings. A primary warning must be
investigated immediately by the driver or
a Jaguar Dealer.

AMBER warning indicators are for
secondary warnings when the driver must
take action and then report the fault to a
Jaguar Dealer at the earliest opportunity.

Other indicators within the instrument
panel indicate system status, such as
blue for high beam and green for direction
indicators, when in operation.

Lamp check

A lamp check is initiated when the ignition
is switched ON and lasts for three
seconds (except the air bag warning
indicator which will remain on for six
seconds). If any warning indicator
remains on after this period, investigate
the cause before driving.

Not all lamps are included in the lamp
check, for example, high beam
headlamps or direction indicators.

Low oil pressure (Red)

This illuminates with the
ignition switched ON and
should go out once the engine

is running.

If the indicator remains ON once the
engine has started or comes ON whilst
driving, loss of oil pressure is indicated.
STOP the engine immediately and
investigate the cause.

Do not restart the engine until the cause of
loss of oil pressure has been identified
and rectified.

First check the engine oil level,
see page 235.

Charge indicator (Red)

If the indicator comes ON when
the engine is running it
indicates that there is either a

battery voltage fault or an generator fault.

Turn OFF all electrical accessories, radio,
climate control, rear screen heater etc.
Try to use the minimum electrical load as
possible, such as power windows,
electric sunroof etc. Report the fault to a
Jaguar Dealer.

Seat belt (Red)

The warning indicator
illuminates when the ignition is
turned ON and:

• The driver’s seat belt is not fastened.
• A passenger is sitting in the front seat

and their seat belt is not fastened.

The indicator should go out when the
driver’s seat belt (and the front
passenger’s if the seat is occupied) is
fastened.

Note: The vehicle must be moving above
16 km/h (10 mph) for the indicator to
illuminate if the passenger seat belt is not
fastened.

Beltminder

The Beltminder feature is a supplemental
warning to the seat belt warning function.

This feature provides additional
reminders to the driver that the driver’s
and/or front passenger’s seat belt is
unbuckled by intermittently sounding a
chime and illuminating the seat belt
warning indicator in the instrument panel.

If the vehicle is moving above
16 km/h (10 mph) and one or both front
seats are occupied and a seat belt is not
fastened, a warning chime will be heard
and the indicator will flash.

The chime sound and the indicator
flashing will last for 10 seconds and then
repeat every 30 seconds for five minutes
or until the belts are fastened or the
vehicle stops.

If the warning indicator stays ON
continuously with the seat belt(s)
fastened, report the fault to a Jaguar
Dealer. It is safe to drive the vehicle with
the indicator ON continuously, provided
that the seat belt(s) is properly fastened.

Ensure that all occupants seat belts are
fastened before driving.

Note: If a heavy object is placed on the
front passenger seat it may activate the
Beltminder feature. It is recommended
that the object be placed in the luggage
compartment.

It is safe to drive the vehicle with the
indicator ON continuously, provided that
the seat belt(s) is properly fastened.
Ensure that all occupants seat belts are
fastened before driving.

Although not advisable, it is possible to
disable the Beltminder function. Please
see a Jaguar Dealer to disable or reinstate
this function.

Brake (Red)

This illuminates when:

• The ignition is ON and the Electric

Parking Brake (EPB) is ON.

• There is a fault with the EPB.
• The brake fluid is low.

If the indicator is ON and there are no
associated messages it means that the
EPB is applied.

If the indicator flashes, there is a fault with
the EPB system and the EPB cannot be
applied.

If the indicator is ON and the message
PARKBRAKE ON is displayed, it means
that the EPB is applied but the vehicle is
moving. Release the parkbrake or stop
the vehicle when it is safe to do so.

If the indicator is ON and the message
LOW BRAKE FLUID message with a RED
priority indicator is displayed on the
message centre, low brake fluid is
indicated. In this case, loss of braking in
one, or both, brake circuits may be
imminent.

!

WARNING:

If the message LOW BRAKE FLUID is
displayed, DO NOT drive the vehicle
until the fault is rectified. Consult a
Jaguar Dealer immediately.

Engine malfunction (Amber)

This indicator comes on when
the ignition is on and remains
on until the engine is started.

If the indicator comes on when the engine
is running then there is an engine
malfunction.

Specialised diagnostic equipment is
required to repair such faults. Report the
fault to a Jaguar Dealer.

The vehicle may go to limp home mode,
with the possibility of reduced engine
performance. Drive the vehicle with
caution.

Anti-lock Braking System (ABS)
(Amber)

If a fault has been detected in
the Anti-lock Braking System
(ABS) or the electric EPB

system, this indicator will illuminate.

A warning message will appear with this
indicator to indicate either ABS fault or
EPB fault.

The brake system will continue to function
normally, but without ABS braking.

Should the indicator come on or stay on
after the bulb check cycle, stop the
vehicle at the first opportunity, turn the
engine OFF and then restart.

If the ABS indicator comes on again, the
vehicle should be driven to a Jaguar
Dealer at the earliest opportunity.

!

WARNING:

If the ABS and brake warning
indicators are ON at the same time, DO
NOT drive the vehicle until the fault is
rectified. Consult a Jaguar Dealer
immediately.
