4-4 On the Road
Engine Temperature (E)
Drive at moderate road and engine
speeds until normal operating
temperature is reached. This is indicated
when the pointer is between the
blue (cold) segment and the red (hot)
segment.
The engine operating temperature will
vary with changes in weather and engine
load. The engine temperature may rise in
some circumstances, such as:
• Idling for long periods in slow moving traffic.
• Driving up a long hill in hot weather.
• Driving slowly or stopping after driving at high speed.
• Towing a trailer or caravan.!WARNING:
1. The radiator cooling fans may continue to run after the ignition
has been switched off but will
automatically switch off when the
engine has cooled sufficiently.
2. It is unsafe to run the engine in an overheated condition.
3. Do not remove the coolant reservoir filler cap while the
engine is hot. If it is essential, then
protect your hands against
escaping steam. SLOWLY turn the
cap anti-clockwise to allow the
steam pressure to escape
completely before removing the
cap. Should the pointer move into the red
segment (
H) of the coolant gauge, stop
the vehicle as soon as it is safely possible,
turn off the engine and open the hood to
allow the engine to cool.

Warning Lights
Warning lights are arranged within the
instrument cluster.
There are two warning lights, 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 lights are for primary
warnings. A primary warning must be
investigated immediately by the driver or
a Jaguar Retailer.
‘AMBER’ warning lights are for secondary
warnings when the driver must take
action and then report the fault to a
Retailer at the earliest opportunity.
Other lights within the instrument cluster
indicate system status, such as blue for
main 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 (excepting the air bag
warning light which will remain on for
6seconds). Ifany wa
rning light remains
on after this period, investigate the cause
before driving.
Note: Not all lamps are included in the
lamp check, for example main beam
headlights or direction indicators.
Low Oil Pressure (RED)
This lights up with the ignition
switched ON and should go
out once the engine is running.
If the light 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.
Caution: Do not restart the engine
until the cause of loss of oil pressure
has been identified and rectified.
First check the engine oil level,
seepage7-6.

4-6 On the Road
Charge Indicator (RED)
This lights up when the ignition
is switched ON and should go
out when the engine is
running.
If the light stays ON when the engine is
running it indicates that there is either a
battery voltage fault or a 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
Retailer.
Seat Belt (RED)
The warning lamp lights when
the ignition is 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 light 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
10 mph (16 km/h) for the lamp to
illuminate if the passeng er seat belt is not
fastened.
Beltminder
The Beltminder feature is a supplemental
warning to the seat be lt 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 light in the instrument cluster. If the vehicle is moving above 10 mph
(16 km/h) and one or both front seats are
occupied and a seat belt is not fastened,
a warning chime will be heard and the
light will flash.
The chime sound and the light 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 light stays ON steady with
the seat belt(s) fastened, report the fault
to a Jaguar Retailer. It is safe to drive the
vehicle with the light ON steady,
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 or reinstate the Beltminder
function. Please see a Jaguar Retailer.
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.

Brake (RED)
Lights up when:
• The ignition is ON and the parkbrake is ON.
• There is a fault with the parkbrake.
• The brake fluid is low.
If the light is ON and there are no
associated messages it means that the
parkbrake is applied.
If the light flashes, th ere is a fault with the

System (ABS) (AMBER)
If a fault has been detected in
the anti-lock brake
system (ABS) or the electric
parkbrake system, this light will
illuminate.
A warning message will appear with this
light to indicate either ABS fault or
parkbrake fault.
The brake system will continue to
function normally, but without ABS
braking.
Should the light come on or stay on after
the bulb check cycle, stop the vehicle at
