BRAKE ASSIST SYSTEM (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
ABS. Applying the brakes very quickly results in the
best BAS assistance. To receive the benefit of the
system, you must apply continuous braking pressure
during the stopping sequence, (do not “pump” the
brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
WARNING!
BAS cannot prevent the natural laws of
ph
ysics from acting on the vehicle, nor
can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped ve-
hicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the
user's safety or the safety of others. TRACTION CONTROL SYSTEM (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration
and stability. A feature of the TCS functions similar to a
limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more
engine torque to be applied to the wheel that is not
spinning. This feature remains active even if TCS and
ESC are in the “Partial Off ” mode. Refer to “Electronic
Stability Control (ESC)” for further information.
ELECTRONIC ROLL MITIGATION (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and the
speed of the vehicle. When ERM determines that the
rate of change of the steering wheel angle and vehicle's
speed are sufficient to potentially cause wheel lift, it
then applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to

NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are
warm [usually after 2 to 5 km of driving]. Because the
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Using the AutoStick
®shift control, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive. ALL WHEEL DRIVE (AWD) (for
versions/markets, where
provided)
This feature provides on-demand All-Wheel Drive
(AWD). The system is automatic with no driver inputs
or additional driving skills required. Under normal
driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,
power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will
be sent to the rear in a pre-emptive effort to improve
vehicle launch and performance characteristics.
All wheels must have the same size and
type tires. Unequal tire sizes must not be
used. Unequal tire size may cause failure
of the power transfer unit .

NOTE:
 For vehicles so equipped, do not attempt to install acenter cap or wheel cover on the compact spare.
 Refer to “Compact Spare Tire” and to “Limited-Use Spare” under “Tires — General Information” in
“Technical Specifications” for additional warnings,
cautions, and information about the spare tire, its
use, and operation.
7. Install the wheel nuts with the cone-shaped end of the nut toward the wheel. Lightly tighten the wheel
nuts.
WARNING!
To avoid the risk of forcing the vehicle
of
f the jack, do not tighten the wheel
nuts fully until the vehicle has been lowered.
Failure to follow this warning may result in per-
sonal injury.
8. Lower the vehicle by turning the jack screw coun- terclockwise with the jack handle.
9. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until
each nut has been tightened twice. The correct
tightness of each lug nut is 130 N·m. If in doubt
about the correct tightness, have them checked with a torque wrench by you authorized dealer or
service station.
10. Lower the jack to its fully closed position.
11. Place the deflated (flat) tire in the cargo area. Do
not stow the deflated tire in the spare tire
stowage location. Have the deflated (flat) tire
repaired or replaced as soon as possible.
12. To stow the winch cable and retainer, fit the assembled jack-handle over the winch drive nut.
Rotate the jack-handle assembly clockwise until
you hear the winch mechanism click three times. It
cannot be over tightened.
13. Stow the jack-handle and jack. Remove the wheel blocks from the vehicle and release the park brake.
14. Check the tire pressure as soon as possible. Adjust the tire pressure as required.
ROAD TIRE INSTALLATION
Vehicles Equipped With Wheel Covers
1. Mount the road tire on the axle.
2.
To ease the installation process for steel wheels with
wheel covers, install two lug nuts on the mounting
studs which are on each side of the valve stem. Install
the lug nuts with the cone shaped end of the nut
toward the wheel. Lightly tighten the lug nuts.

3. Align the valve notch in the wheel cover with the valve stem on the wheel. Install the cover by hand, snapping the cover over the two lug nuts. Do not
use a hammer or excessive force to install the cover.
4. Install the remaining lug nuts with the cone shaped end of the nut toward the wheel. Lightly tighten the
lug nuts.

7. After 40 km check the lug nut torque with a torque wrench to ensure that all lug nuts are properly
seated against the wheel.

where provided)
Small punctures up to 6 mm in the tire tread can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT
can be used in outside temperatures down to approxi-
mately ­20°C.
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 160 km with a maximum
speed of 88 km/h.
TIREFIT Storage
The TIREFIT kit is located in the trunk.
