BRAKE PRECAUTIONS
WARNING: Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or
driving from standing water to dry the
brakes.
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and travel further.
Maintain pressure on the brake pedal. BRAKE OVER ACCELERATOR
- RAPTOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Note:
Certain drive modes can disable
brake over accelerator for off-road driving.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.

CHECKING THE BRAKE FLUID
WARNING: Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the MIN and the MAX marks on the
reservoir.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications.

Specifications (page 574).

use your vehicle. Your vehicle lets you know when an oil
change is due by displaying a message in
the information display.

vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.When to Expect the OIL CHANGE REQUIRED Message
