G

WARNING

When jacking up the vehicle, only use a

suitable jack. Observe the manufacturer’s

safety instructions.
The jack must be designed for jacking up

this vehicle at the jack take-up brackets

built into both sides of the vehicle.
The jack is intended only for lifting the

vehicle briefly for wheel changes. It is not

suited for performing maintenance work

under the vehicle. To help avoid personal

injury, use the jack only to lift the vehicle

during a wheel change.
Never get beneath the vehicle while it is

supported by the jack. Keep hands and feet

away from the area under the lifted vehicle.

Always lower the vehicle onto sufficient

capacity jackstands before working under

the vehicle.
Always firmly engage the parking brake and

block the wheels with wheel chocks or other

sizeable objects before raising the vehi-

cle with the jack. Do not release the parking

brake while the vehicle is raised.
Make sure the ground on which the vehicle

is standing and where you place the jack is

solid, level and not slippery. If necessary,

use a large underlay. On slippery surfaces,

such as tiled floors, you should use a non-

slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects

to support the jack. Otherwise the jack may

not be able to achieve its load-bearing

capacity if it is not at its full height.
The jack must always be vertical when in

use. Always try to use the jack on level sur-

face. If you do not position the jack cor-

rectly, the vehicle can fall off the jack and

seriously or fatally injure you or others.

of whether the high-voltage battery is

charged or not. Jump starting will not help

to start the drive system if the high-volt-

age battery is drained. The high-voltage

battery must then be charged.
The drive system can be started with jumper

cables and the fully charged battery of

another vehicle or an equivalent starter

pack.
Observe the following:

R

Do not start the drive system if the bat-

tery is frozen. Let the battery thaw out

first.

R

Only jump start from batteries with the

same voltage rating (12 V). Jump starting

with a more powerful battery could dam-

age the vehicle’s electrical system. Such

damage will not be covered by the smart

Limited Warranty.

R

Only use jumper cables with sufficient

cross-section and insulated terminal

clamps.

R

Should the battery be drained com-

pletely, let the donating power source

charge the vehicle for several minutes

before reattempting the starting proc-

ess.

About towing

This section offers information on towing

methods for breakdown situations and

emergency towing.

Recommended towing method - Break-

down situation

!

To prevent damage during transport, do

not tie down the vehicle by its chassis or

suspension parts — use only wheel straps

to position and hold down the vehicle.
Improper tie down on a flatbed carrier

truck or trailer can damage suspension

parts and body panels.

smart recommends that the vehicle be

transported with all wheels off the ground

using a flatbed carrier truck or appropri-

ate wheel lift/dolly equipment.
Always have your vehicle transported:

R

when the N warning lamp for the high-

voltage system lights up in the instru-

ment cluster

R

when the

Do not tow (away)

WARNING

With the drive system inactive, there is no

power assistance for the brake and steering

systems. In this case, it is important to

keep in mind that a considerably higher

degree of effort is necessary to brake and

steer the vehicle. Adapt your driving

accordingly.

!

The vehicle may be towed only for dis-

tances up to 30 miles (50 km) and at a

speed not to exceed 30 mph (50 km/h).
Otherwise, the electric drive or the

high-voltage system could be damaged.

!

Do not tow other vehicles.

Otherwise, the drive system or compo-

nents of the high-voltage system could be

damaged.

!

Do not tow the vehicle with the front

axle raised. Doing so may cause serious

damage to the brake system which is not

covered by the smart Limited Warranty.

!

Before towing the vehicle observe the

following instructions:

R

Do not tow with sling-type equipment

attached to suspension parts. This may

cause damage to the supports if towing

on a bumpy road.

R

Towing the vehicle should only be done

using the properly installed towing

eye bolt. Never attach a tow cable, tow

rope, or tow rod to the vehicle chassis,

frame, or suspension parts.

!

Make sure the gear selector lever is in

neutral position N while towing the

vehicle. Doing otherwise may result in

significant drive train damage.

!

Towing the vehicle with a luggage rack*

mounted is not permissible. The vehicle

must not be towed by the luggage rack*.
